1. Field of the Invention
The present invention relates to a digital camera, and in particular,
to a digital camera in which a communication section which outputs
image data to an external device is provided, and to a method of
recycling a digital camera.
2. Description of the Related Art
At present, digital cameras with an infrared communication function
which can perform data communication with an external device, such
as a computer or the like, by using infrared radiation, have been
used.
As disclosed in Japanese Patent Application Laid-Open (JP-A) No.
9-149315, when an image which was photographed is transmitted to
a personal computer or the like as digital data, it is not necessary
to connect the digital camera and a personal computer with a predetermined
cable, and the image data is transmitted and received through a
communication section provided at the digital camera, by using infrared
radiation.
However, despite the fact that the communication section is not
needed during photographing, it is a portion of the body of the
digital camera and is therefore exposed at the exterior of the digital
camera. Therefore, there are cases in which the user touches the
communication section and fingerprints are formed on the communication
section, or dust or the like adheres to the communication section.
Moreover, there is a problem in that, if the digital camera is hit
against an object, while it is being carried, the communication
section will be damaged and image data cannot be taken out normally
from the communication section.
SUMMARY OF THE INVENTION
Accordingly, in order to solve the above-described problems, an
object of the present invention is to provide a digital camera in
which, by covering a communication section of the digital camera
with a protecting means or cover, the communication section can
be protected and the image data can be taken out normally. Moreover,
the present invention relates to a method of recycling a digital
camera in which, after image data is taken out from a communication
section of a digital camera, by covering the communication section
once again with the protecting means, the digital camera can be
used again.
A first aspect of the present invention is a method of recycling
a digital camera comprising: a communication section which outputs
image data to an external device; and protecting means which covers
the communication section and which is removed at times when the
image data is output, wherein, after the protecting means is removed
and the image data is taken out from the communication section,
the communication section is once again covered by the protecting
means.
In accordance with this structure, after the protecting means is
removed and the image data is taken out from the communication section,
by covering the communication section once again with the protecting
means so as to return the digital camera to its original state,
the digital camera can be recycled easily. As a result, the costs
of the digital camera, such as the manufacturing cost, can be reduced.
A second aspect of the present invention is a digital camera comprising
a communication section which outputs image data to an external
device, and protecting means or a protecting cover which covers
the communication section and is removed at times when the image
data is output.
In accordance with this structure, by covering the communication
section, which outputs the image data to an external device, with
the protecting means or cover, the communication section can be
protected. Therefore, the user can be prevented from touching the
communication section, and the communication section will not be
dirtied or damaged. Moreover, when data communication with an external
device is carried out, if the protecting means is removed, accurate
image data can be taken out from the communication section.
In the present invention, the protecting means preferably covers
the communication section and charging terminals for charging a
power source.
In accordance with this structure, by covering, with the protecting
means or cover, the communication section and the terminals for
charging the power source, the charging terminals are not dirtied
or damaged. Therefore, the function of the charging terminals can
be maintained.
In the present invention, the protecting means is preferably elastic.
In accordance with this structure, the protecting means is elastic.
Therefore, even if the communication section is hit by an object
from the exterior, due to the elasticity of the protecting means,
the communication section can be reliably protected.
In the present invention, the protecting means is preferably a
protective film which wraps up the communication section and the
charging terminals.
In accordance with this structure, the protecting means is a protection
film which wraps up the communication section and the charging terminals.
Therefore, the protection film cannot be removed inadvertently,
and the communication section and the charging terminals can be
better protected.
The present invention may further comprise indicating means for
indicating that the protecting means was removed.
In accordance with this structure, because the indicating means
is provided at the digital camera, it can easily be recognized that
the protecting means has been removed. Accordingly, in particular,
reliability of the data which is stored inside the digital camera,
for example, whether or not the data has been read-out or rewritten
arbitrarily can be confirmed easily.
In the present invention, the indicating means is preferably a
"seal broken" mark which is exposed when the protecting
means is removed.
In accordance with this structure, because the "seal broken"
mark is exposed when the protecting means is peeled off, it is easy
to confirm the reliability of the image data. Moreover, at regular
times, the "seal broken" mark is not exposed at the exterior
of the digital camera. Therefore, degrees of freedom in designing
of the digital camera can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
A digital camera relating to an embodiment of the present invention
will be described hereinafter with reference to the accompanying
drawings. FIGS. 1A and 1B are exterior structural views which show
the exterior of the digital camera.
As illustrated in FIG. 1A, a digital camera 10 of the present embodiment
is formed of a camera body 12 which photographs a subject and stores
image data, and an infrared communication device 14 which performs
data communication with an external device (not illustrated) such
as a computer on the basis of the stored image data.
The contour of the camera body 12 is formed in the shape of a box.
A photographing lens 16 is provided at the front surface of the
camera body 12 at a position somewhat toward the right (in FIG.
1A) of the center. Moreover, a guide rail 18 is formed in the top
surface of the camera body 12. As illustrated in FIG. 1B, a lens
cover 20 which protects the photographing lens 16 slides along this
guide rail 18 in the direction of A and in the direction opposite
thereto. Further, by opening and dosing the lens cover 20, a power
switch is turned ON/OFF. Therefore, the lens cover 20 also serves
as a power switch.
Further, a shutter button 22 is provided in the top surface of
the camera body 12. By pressing the shutter button 22, image data
is stored in a memory 24 (see FIG. 4) which will be described later.
Moreover, in the upper side of the front face of the camera body
12, an optical finder 26 is provided. Next to the optical finder
26 (in the present embodiment, at the right side of the optical
finder 26), a flash 28 which emits supplementary light is provided.
As shown in FIG. 2, the infrared communication device 14 is formed
integrally with the camera body 12, and, in the same way as the
camera body 12, is formed in the shape of a box. In the front face
of the infrared communication device 14, a window 30, which serves
as a communication section which sends image data stored in the
memory 24 to a computer, is provided. Moreover, charging terminals
32 for charging a power source are provided beneath the window 30.
As shown in FIG. 3, a "seal broken" mark 34, which is
a sticker on which the words "seal broken" have been printed,
is firmly adhered to the bottom surface of the infrared communication
device 14. Further, although not illustrated, the words "seal
broken" may be directly marked on a portion of the infrared
communication device 14 of the digital camera 10.
As illustrated in FIGS. 1A, 1B and 2, a protective film 36 (the
portion indicated by hatching in FIGS. 1A, 1B and 2), which integrally
covers the "seal broken" mark 34, the window 30 and the
charging terminals 32, is wrapped around the outer side of the infrared
communication device 14. The protection film 36 closely contacts
and is firmly attached to the outer side of the infrared communication
device 14, so as to wrap up the window 30 and the charging terminals
32. Also, paper may be used in place of the protection film 36.
The protection film 36 is formed of polypropylene and is elastic.
Thus, the protective film 36 functions as a cushion which effectively
protects the window 30, and further, if the protective film 36 become
caught on an object, it is difficult for it to be peeled off without
the user's knowledge.
As described above, by covering the window 30 with the protection
film 36, fingerprints, dust, and the like do not adhere to the window
30, the window 30 can be prevented from being damaged, and the function
of the infrared communication device 14 can be maintained. Further,
by covering the charging terminals 32 for charging the power source,
it is also possible to maintain the function of the charging terminals
32.
Further, by covering the "seal broken" mark 34 (indicating
means), once the protection film 36 is removed, the "seal broken"
mark 34 printed "seal broken" will be exposed. Therefore,
in particular, in a case in which the digital camera 10 is lost,
it can be ascertained whether or not internal data was read or written
arbitrarily by strangers, and the reliability of the internal data
can be confirmed easily.
Moreover, at regular times (at times when the protection film 36
is attached), the "seal broken" mark 34 is not exposed
at the surface (body) of the digital camera 10, and is first exposed
when the protection film 36 is removed. Therefore, the degrees of
freedom in design of the digital camera 10 can be improved.
Further, the "seal broken" mark 34 does not necessarily
have to be provided at the bottom surface of the infrared communication
device 14. Provided that the "seal broken" mark 34 is
covered by the protective film 36, the "seal broken" mark
34 may be provided at the top surface or a side surface of the infrared
communication device 14. Further, even if the "seal broken"
mark 34 is not covered by the protective film 36, for example, instead
of a "seal broken" mark 34, a mark on which the words
"protective film attached" or the like are printed may
be firmly adhered to the side of the camera main body 12, or the
words "protective film attached" may be marked on the
body of the digital camera 10. In this way as well, the fact that
the protection film 36 was initially fixed to the window 30 of the
infrared communication device 14 can be indicated and ascertained
easily.
Next, on the basis of the block diagram shown in FIG. 4, the internal
structure of the digital camera of the present embodiment will be
described. As illustrated in FIG. 4, the digital camera 10 comprises
the photographing lens 16 which photographs a subject; the flash
28 which irradiate the subject with additional light; a shutter/aperture
mechanism 40; a driving circuit 42 which outputs driving signals
to an image pick-up device 44; the image pick-up device 44 (CCD)
which outputs image signals; an analog signal processing circuit
46 serving as a signal processing section; an A/D converting section
48 which converts analog signals to digital signals; a digital signal
processing circuit 50; the memory 24 which stores image signals
as image data; a CPU 52 which controls the entire digital camera
10; the infrared communication device 14 which performs data communication;
a shutter switch 54; a lens cover switch 56; a secondary battery
58 which is a power source; and the charging terminals 32 for charging
the power source.
Further, a laser printer section 60 and an output section including
a processor section 62 are provided at the exterior of the infrared
communication device 14. The laser printer section 60 records an
image onto a photographic printing paper on the basis of the image
data transmitted from the infrared communication device 14. The
processor section 62 carries out various processings such as color
development and the like on the photographic printing paper onto
which an image has been recorded by the laser printer section 60.
Next, operation of the digital camera of the present embodiment
will be described.
When the lens cover 20 is opened, the required power is supplied
from the secondary battery 58 to respective sections of the digital
camera 10 represented by blocks in the block diagram of FIG. 4.
Then, at times when the degree of illumination is low, the flash
38 is used to provide supplementary light. When a shutter switch
54 is pressed, the reflected light which is reflected from the subject
is incident on the photographing lens 16 and the shutter/aperture
mechanism 40, and is focalized on the image pick-up device 44. Here,
the shutter of the shutter/aperture mechanism 40 is a mechanical
shutter and prevents light from hitting and smears from being generated
when a signal is read from the pick-up device 44. Moreover, the
aperture of the shutter/aperture mechanism 40 is formed by the electronic
shutter of the image pick-up device 44 and a mechanical shutter,
and controls the amount of exposure to light on the image pick-up
device 44.
Then, the image pick-up device 44 is driven by a photographing
device driver (not illustrated) at a timing generated by a timing
generating circuit (not illustrated), and outputs an image signal
which is image data. Further, depending on the driving voltage conditions
of the image pick-up device 44, the photographing device driver
may be unnecessary.
After the image signal is subjected to signal processing at the
analog signal processing section 46, at the A/D converting section
48, the image signal is converted to a digital signal. At a digital
signal processing section 50, the signal is again subjected to signal
processing and is stored in the memory 24. Further, when the image
data is compressed and stored, compression is carried out at the
digital signal processing section 50 or at the CPU 52.
Next, when the image data stored in the memory 24 is to be taken
out, the protection film 36 adhered to the infrared communication
device 14 and covering the window 30 is removed. Thereafter, due
to a driving instruction from the CPU 52, the image data stored
in the memory 24 is illuminated as infrared light from the window
30 toward an external device, such as a computer or the like (not
shown). In addition to the transmission of image data to an external
device such as a computer being carried out through the window 30
controlled by the CPU 52, the reading of maintenance data, the reading
of settings and the like are also carried out through the window
30.
Thereafter, if the communication of data to an external computer
is completed, the image data stored in the memory 24 is deleted.
Then, in the same way as the initial digital camera 10 illustrated
in FIGS. 1A and 1B and 2, once again, the protection film 36 is
affixed to the infrared communication device 14 so as to cover the
window 30, and recycling of the digital camera 10 is performed.
As described above, by affixing the protection film 36 and reusing
(recycling) the digital camera 10 which was used once, a reduction
in manufacturing costs and the like can be realized.
Further, as an alternative example of the digital camera 10 of
the above-described embodiment, charging may be performed by non-contact-type
electromagnetic induction, instead of by contact charging by use
of the charging terminals 32.
In this alternative example, there is no need to form the charging
terminals 32 on the body of the digital camera, and thus no need
to cover charging terminals with the protection film 36.
According to the present invention, by covering the communication
section with a protecting means, the communication section can be
protected easily. Therefore, the communication section can be prevented
from being touched by the user, and is not dirtied nor damaged.
As a result, when data communication with an external device is
performed, accurate image data can be taken out from the communication
section.
Further, after removing the protecting means to take out the image
data from the communication section, by covering the communication
section once again with the protecting means so as to set the digital
camera in its original state by recycling method of the present
invention, the digital camera can be recycled easily. As a result,
a reduction in cost can be realized. |
