This pressure plate 7 is provided with a copying window 7A for exposing the LCD recording portion 3D to the back surface of the film. Further, a fitting claw 7B that is detachably fitted to a fitting portion 6F provided on the pressure plate spring 6 is provided. Here, FIG. 2 shows the positional relationship between the pressure plate 7, the date module 3 and the film F, and the light from the projection lamp 8 is reflected by the mirror 9.
LCD that works as a light valve according to date information
By being exposed to the back side of the film F via the imprinting section 3D, imprinting of the date, time, etc. is made on a part of the image taken by the taking lens.

Therefore, in such a structure, after the pressure plate spring 6 is attached to the inner cover 4 by caulking, the inner cover 4 is attached to the inner surface of the back cover 1 by a screw so as to sandwich the date module 3. As a result, the date module 3 is incorporated. In this assembled state, the LCD display section of the date module 3 and the imprinting sections 3C and 3D are fitted into the display window 1D and the through hole 4D and positioned. As shown in FIG. 3, the inspection of the date module 3 incorporated on the inner surface side of the back cover 1 is performed from the inner surface side of the back cover 1 from the inner surface side of the exposure hole 6A of the pressure plate spring 6, the exposed cutout portion 6B, and the inner cover 4. This is performed by inserting the inspection pin P through the exposure hole 4A and bringing it into contact with the inspection input contact for input.

Therefore, the date module 3 can be smoothly inspected without damaging or soiling the outer surface side of the back cover 1 forming the external appearance of the camera body. Further, the pressure plate spring 6 side is also provided with an exposure hole 6A and an exposure notch 6B so that the date module 3 can be assembled and inspected with the pressure plate spring 6 attached to the inner cover 4. It is not affected by the troubles that occur during the installation (in this case, the caulking is defective, but in the case of screwing, the screw hole is damaged, etc.). If the inner cover 4 to which the pressure plate spring 6 is not attached and the date module 3 is assembled and inspected, if caulking failure occurs during the subsequent attachment of the pressure plate spring 6, the inner cover 4 is replaced and the date module 3 is replaced. It becomes necessary to re-inspect, and the defect rate increases accordingly.

By assembling and supporting the pressure plate 7 with the pressure plate spring 6 after the inspection, the assembly is completed, and the inspection input contact 3B exposed to the outside is covered with the pressure plate 7 and blinded. Therefore, the erroneous operation by the user can be prevented. In this embodiment, the input contact 3 for inspection is used.
Although not all B is exposed to the outside through the exposure hole 4A of the inner cover 4, all B may be exposed. In short, the number of the exposure holes 4A provided in the inner cover 4 may be determined as needed. For example, when the functions used by the date module 3 are different depending on the camera model, if the number of the exposure holes 4A provided in the inner cover 4 is determined for each model, incorrect input will not be made during the inspection. .

FIG. 4 shows, for example, five input contacts SR, M, S among the inspection input contacts 3B of the date module 3.
The case where the exposure hole 4A of the inner cover 4 is provided so that only 1, S2 and VDD are used (exposed) is shown. First, when the inspection pin inputs (ON) to the input contact SR, the system is reset and the date. When the module 3 is turned on, the year, month, and day are set to 87.1.1, for example. Next, input pin S for inspection
When R and M are turned on, all lights are turned on, and it is confirmed that the LCD display unit and the imprinting units 3C and 3D are turned on. When the input contact M is turned on once, the date mode is selected, and when the input contact S1 is turned on in that state,
The correction position can be switched whether to change the month or the day, and the operation of the correction can be confirmed by turning on the input contact S2. Further, when the input contact M is turned on again, the time is set, and when the input contact S1 is turned on in that state, the correction position can be switched to change the hour, minute, or second, and the input contact S2 can be changed. When it is ON, the operation of the correction can be confirmed. Further, when the input contact M is turned on again, the date imprinting is not performed, and the state is confirmed. In this case, date change button 2
Input contact 3A having the same function as input contacts M, S1, S2
Shall face each other. As other input contacts for inspection, for example, adjustment of the imprinting time required depending on the sensitivity of the film used, test input of the imprinting trigger,
In some cases, when two LCD imprinting sections are provided corresponding to standard photography and panoramic photography, switching confirmation of the imprinting section or activation of function check of the date module itself is performed.

[0016]

As described above, according to the present invention, when the date module is installed on the inner surface of the back cover of the camera body,
The test input contacts provided on the date module are exposed to the outside so that the built-in date module can be inspected from the inner side of the back cover, so the outer side of the back cover, which is the external appearance of the camera body at the time of inspection, is damaged. There is no risk of soiling. Also, because the input contact necessary for inspection is exposed to the outside, the inspection can be performed smoothly,
The time required for the inspection can also be shortened.
