DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for taking pictures and the like.

[0002]

2. Description of the Related Art At the time of manufacturing a camera, Japanese Patent Application Laid-Open No. 58-18 / 1983
As described in Japanese Patent Application Laid-Open No. 9619, initial data (reference value) relating to photographing such as exposure, photometry or focus adjustment is PR.
It is written in the OM or the like, and enables proper shooting of the camera. To write the initial data, an external device for data input is connected to a terminal provided in a film cartridge storage room or the like of the camera, predetermined external data is output from the external device, and the data is written to a PROM or the like built in the camera. Done by typing.

[0003]

However, the above-described camera initial data writing technique has the following problems.

For example, as a camera, Japanese Patent Application Laid-Open No. 7-244
As described in JP-A-330, there has been proposed an apparatus having a main body having a photographing function and a separate product detachable from the main body. The separate product functions as a remote control or the like. In such a camera, when each of the main body and the separate product has a memory such as an EEPROM,
It is necessary to write the initial data to the memories of the main unit and the separate product. For this reason, it is conceivable to provide a data input terminal on each of the camera body and the separate product, and to write initial data into each of the main body and the separate product through each terminal during camera manufacture. However, the writing of such initial data is performed by a normal camera (camera consisting of the main body only).
This requires about twice as much time and labor as the writing operation, and further requires an apparatus and a jig for writing separately for the camera body and a separate product.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a camera capable of efficiently writing initial data with simple equipment.

[0006]

In order to achieve the above object, a camera according to the present invention comprises a main body having a photographing lens, a photographing function, and a built-in memory for storing initial data relating to photographing. , Which can be attached to and detached from the position that covers the front of the taking lens, and can be attached and detached to positions other than the position that covers the front of the taking lens. A lens cover that functions as a means and has a built-in memory for storing initial data, an input terminal provided on at least one of the main body and the lens cover for inputting initial data from an external device, And communication means for transmitting the initial data to one of the main body and the lens cover.

In the camera according to the present invention, the communication means transmits and receives data between the main body and the lens cover when the lens cover is attached to a position other than the position covering the front surface of the taking lens. Characterized in that:

According to these inventions, at the time of manufacturing,
By using the communication means, it is possible to write the initial data to both the camera body and the lens cover by simply inputting the initial data to either of them. Therefore, it is not necessary to input initial data individually to the main body and the lens cover. Initial data can be written to both sides. Therefore, the cost of the manufacturing equipment can be reduced. Further, since the initial data can be written to the main body and the lens cover at the same time, the work of writing the initial data to each of the main body and the lens cover can be efficiently performed.

It has substantially the same cross-sectional shape as that of the first embodiment, and has four pins 302 projecting from the upper end surface thereof. The pins 302 are configured to come into contact with the terminals 57a to 57d in the cartridge storage chamber 54 when the jig 301 is inserted into the cartridge storage chamber 54. The jig 301 is connected to a driver 303.
The driver 303 is for amplifying a signal that is data. In addition, the driver 303 includes an external device 304
It is connected to the. The external device 304 stores initial data to be input to the main body 10 and the card 60, and can appropriately output the initial data. As the external device 304, for example, a personal computer is used.

[0071]

As described above, according to the present invention, the following effects can be obtained.

At the time of manufacturing, by using communication means, initial data can be written to either the camera body or the lens cover by simply inputting the initial data to either of them. For this reason, it is not necessary to input initial data individually to the main body and the lens cover, and if there is one external device or jig capable of inputting the initial data to one of the main body and the lens cover, the main body and the lens cover are not required. Initial data can be written to both sides. Therefore, the cost of the manufacturing equipment can be reduced.

Since the initial data can be written to the main body and the lens cover at the same time, the work of writing the initial data to each of the main body and the lens cover can be efficiently performed.
