It is controlled by a control signal /CPU0N supplied via the CPU0N.

In other words, this control signal /CPU0N is LOW.
When this happens, the regulator 78 becomes ENABLE and the microcomputer 75 starts operating.

In addition, in FIG. 6, 80 is the light receiving sensor output,
The microcomputer 75 detects this and identifies the code from the external remote controller.

That is, the microcomputer 75 detects the detection output of the sensor 77, identifies the code, and serially transmits control data based on the identified code to the camera body 1 via the serial communication line.

In this embodiment, the codes that can be identified by the microcomputer 75 are all codes that can be operated by the external remote control and correspond to various data input functions such as a photographing function, a playback function, and a date.

Furthermore, 81 to 83 are the camera body 1 and this power cover 2.
These serial communication lines are connected to the microcomputer 75 in the camera body 1, and these serial communication lines are formed by the connection cable 54 by inserting the connector 21 into the connector connection part of the camera body 1, and are connected to each of the film photographing apparatuses 2. Each control data corresponding to the output signal from the switch and the lighting detection signal is supplied to the camera body 1.

On the other hand, the camera body 1 operates the power cover 20 in response to the operation of each of the operation buttons 7 and 8 provided on the camera body 1 or in response to an output signal from the film photographing device 2.
A microcomputer 85 controls the operation of the camera 1 according to control signals supplied from the power supply coupler 20, and an S/P converts serial control data from the power coupler 20 into parallel data.

Note that 91 in FIG. 6 is a character generator, and the output code of this character generator 91 is for displaying characters, etc. on the monitor 4 (not shown).

Next, the operation of the photographing system configured as described above will be explained.

First, by attaching the power cover 20 of the interface adapter 5 to the battery box 19 of the camera body 1 and connecting the interface adapter 5 to the film photographing device 2 and the AC adapter 3, the AC
Power from the adapter 3 is supplied to the film photographing device 2 via the interface adapter 5, and the power cover 2 of the interface adapter S
0 to the camera body 1.

Further, the microcomputer 85 of the camera body 1 is activated by the lighting detection signal from the film photographing device 2.
The film photographing device 2 ignores commands from the operation buttons 7.8 and is supplied with power via the power converter 20.
It is set to accept and accept control signals from each of the switches 70 to 73.

Therefore, for example, the release switch 7 of the photographing device 2
Depending on the control signal from 0, the camera 1 takes a picture, whereas the release button 7 of the camera body 1
Shooting will not take place even if you operate .

That is, as described above, the camera l is connected to the power supply cover 20.
When the camera body 1 is connected to the film photographing device 2 via the camera body 1, the control signal /CPU0N of the microcomputer 85 in the camera body 1 is set to LOW.

As a result, the regulator 78 in the power coupler 20
becomes ENABLE, and the microcomputer 7 in this Kabra 20
5 becomes the operating state.

When controlling the operation of the camera body 1 in accordance with a control signal from the film photographing device 2, the microcomputer 75 of the power converter 20 reads the control signal transmitted from the photographing device 2 and performs a predetermined operation. The control data is encoded into control data, and this control data is serially transmitted to the S/P converter 86 of the camera body 1 via the serial communication line.

The microcomputer 85 of the camera body 1 takes in data from the S/P converter 86 and controls the camera body 1 based on this data.

On the other hand, when the operation button 7.8 of the camera body 1 is operated, the microcone-85 inside the camera body 1
does not accept commands from operating the operation buttons 7 and 8 and does not operate.

Note that when the negative/positive inversion switch 50 of the film photographing device 2 is in the negative state, the negative/positive inversion circuit in the camera 1 is activated to invert the imaging output to negative/positive.
In the case of a positive state, the carrier output is output as is.

In addition, the output video signal is recorded on the magnetic disk inside the camera body and played back on the external monitor. If you do not like the playback screen, you can temporarily record it on the magnetic disk by operating the erase button. erase that video signal.

Incidentally, in the above-described embodiment, the operation of the operation buttons 7 and 8 of the camera body 1 is prohibited in response to the lighting detection signal from the film photographing device 2. 1 operation button 7.8
It may be possible to prohibit not only the operation by the external remote controller detected by the power supply cover 20 but also the operation by the external remote control detected by the power supply cover 20.

As described above, in this embodiment, the operation button of the camera itself for the camera body 1 attached to the film photographing apparatus 2 is activated by the lighting detection signal that detects the lighting state of the fluorescent lamp 42 of the film photographing apparatus 2. 7.8 operations are now prohibited.

Therefore, when shooting camera film, it is no longer possible to operate the operation buttons 7 and 8 of the camera 1 to take pictures, etc.
It is possible to prevent photographing with the camera 1 turned off.

Further, the film photographing device 2 can accurately support the camera body l on the film mounting table 36, and is equipped with a light source (backlight) for transparent originals such as the camera film 24. , close-up photography of such films can be done extremely accurately and easily.

In the above-mentioned embodiment, operation using the operation buttons 7 and 8 of the camera 1 was prohibited at the stage when the fluorescent lamp 42 of the film photographing device 2 was turned on. The operation using the operation buttons 7.8 of the camera 1 may be prohibited at this stage.

Further, the height of the optical chamber 30 may be made variable depending on the subject other than the transparent original, and in that case, the light from the camera flash may be reflected instead of the fluorescent lamp 42. You may also do so.

(Effects of the Invention) According to the photographing device of the present invention as described above, close-up photography of camera film can be performed extremely easily and accurately.

Further, according to the photographing system of the present invention, when taking close-up photographs with the camera, the operation using the operation buttons of the camera itself is prohibited, and the operation is performed using the operation buttons of the film photographing device. It is possible to prevent the camera from shaking.
