Hereinafter, referring to the flowchart of FIG.
The operation of the MCPU 26 on the camera body will be described in detail.
When a power supply (battery) is loaded into the camera body, the MCPU 2
6 starts operation, and this routine “MCPU main” is called.

First, at step S1, the MCPU 26
Determines whether the PWSW 36 of the camera is on. Here, when the PWSW 36 is turned on, the processing after step S4 is executed, and when the PWSW 36 is turned off, the processing after step S2 is executed. In step S2, a subroutine "communication", which will be described in detail later, is called, and communication with the SCPU 46 is performed.

Then, in step S3, standby processing 1 is performed.

This standby processing 1 is a so-called MCPU 2
Before stopping the operation of No. 6, the MCPU 26 sets conditions for restarting the operation after the stop. In the standby process 1, the operation is set to start when the power switch PWSW 36 is turned on. And MC
The operation of the PU 26 is stopped. When the standby is released, the subroutine "MCPU main" is executed again from the beginning.

On the other hand, in step S4, the taking lens (not shown) is extended from the retracted position (not shown) to the wide position. Next, at step S5, the timer 1 built in the MCPU 26 starts counting. This timer 1
Is a counter that counts up every predetermined time. The counter value is cleared to 0 (reset), and the counter starts. Then, in step S6, the main capacitor (not shown) included in the flash circuit 28 is charged.

Subsequently, in step S7, the line MRM
If the signal level at 42 is detected and the operation device has been removed, the processing from step S8 is performed, and if not, the processing from step S10 is performed.

That is, in step S8, the remote control light-receiving circuit 29 is turned on, and is in a state of waiting for a remote control signal. Then, in step S9, a remote control signal receiving process is performed. Here, when the remote control signal is received, the process branches to the exposure process in step S13 and subsequent steps according to the determination in step S22.

On the other hand, in step S10, the remote control light receiving circuit 29 is turned off, and the state of waiting for reception of the remote control signal is released. Then, in step S11, a subroutine "communication" described later in detail is called, and communication with the SCPU 46 is performed.

Subsequently, in step S12, it is determined whether or not the 1RSW 39 is turned on by pressing the release button 2. Here, when the 1RSW 39 is turned off, the determination in step S22 is executed,
If it is turned on, the processing of step S13 and subsequent steps is executed.

In step S13, a subject brightness value is obtained from the photometry circuit 30.

Then, in step S14, the AF circuit 6
The distance to the subject is obtained based on the signal input through the camera 2 and the driving amount data of the photographing lens for driving the photographing lens to the in-focus position is calculated. The focus adjustment is performed by controlling the motor 33 based on the driving amount.

Next, in step S15, step S
Based on the subject brightness value obtained in step 13 and the film sensitivity detected by a film sensitivity detection circuit (not shown),
The shutter opening time at which the proper exposure is obtained is calculated by a known technique.

In step S16, it is determined whether a remote control signal has been received. Here, if it is determined that the remote control has been received, steps S20 and subsequent steps are executed, and if it is determined that the remote control has not been received, the determination of step S17 is executed.

In step S17, the WRSW 50 is connected to the camera via the communication cable 8 while the operating device is connected to the camera.
Is turned on. Here, WRSW50
If it is determined that is turned on, step S20 and subsequent steps are executed. If it is determined that it is turned off, step S1 is performed.
The judgment of 8 is executed.

In step S18, it is determined whether or not the 2RSW 40, which is turned on in conjunction with the deep pressing operation of the release button 2, is turned on. Here, if it is determined that the 2RSW 40 is turned on, steps S20 and subsequent steps are executed, and if it is determined that the 2RSW 40 is turned off, step S19 is performed.
Is determined.

In step S19, it is determined whether 1RSW 39 is on. Here, if it is determined that the switch is on, step S18 is executed again, and if it is determined that the switch is off, the process jumps to step S5.

In the following step S20, the above step S
Exposure is performed on a film (not shown) based on the 15 exposure calculation results. Then, in step S21, the film feed motor 63 is driven to wind up the film by one frame. Then, the frame number counter incorporated in the MCPU 26 is incremented, and the process jumps to step S5.

On the other hand, in step S22, it is determined whether or not a remote control signal has been received from the operating device in step S9. Here, when the remote control signal is received, the photographing sequence from step S13 is executed, and when not received, the determination in step S23 is executed.

In step S23, while the operating device is connected to the camera body via the communication cable 8, the W
It is determined whether the RSW 50 has been turned on. Where W
If it is determined that the RSW 50 has been turned on, step S1
The photographing sequence of 3 or less is executed, and if it is determined that it is not turned on, the judgment of step S24 is executed.

In the following step S24, it is determined whether or not either ZUSW 37 or ZDSW 38 has been turned on. Here, if it is determined that any of them is turned on, step S25 is executed, and if it is determined that they are not turned on, the judgment of step S26 is executed.

That is, in step S25, the zoom motor 24 is driven to change the focal length of the photographing lens, and the process jumps to step S5.

In step S26, it is determined whether or not BKSW 35 has changed. Here, if it is determined that the BKSW 35 has changed, step S27 is performed, and if it is determined that the BKSW 35 has not changed, the determination of step S28 is performed.

In the following step S27, a process associated with opening and closing the back cover is executed. If the back cover is closed, the film feed motor 63 is driven to wind up the film, the frame number counter built in the MCPU 26 is set to the first frame, and the process jumps to step S5. Conversely, if the back cover has been opened, the frame number counter built in the MCPU 26 is cleared to 0, and the process jumps to step S5.

In step S28, it is determined whether the power switch 1 of the camera is on. Here, if the power switch 1 is turned on, step S29
Is determined, and if it is off, the processing of step S2 and subsequent steps is performed.

In the following step S29, the timer 1 overflows when a predetermined time elapses after the counting of the timer 1 is started. It is determined whether or not the timer 1 has overflowed.
If the processing does not overflow, the processing from step S7 is repeated. This is because when the operation switch such as the power switch 1 is not operated even after the predetermined time elapses, the MCP
This is for putting U26 in a standby state.

In step S30, a subroutine "communication", which will be described in detail later, is called, and communication with the SCPU 46 is performed.

In the following step S31, a standby process 2 is performed.

This standby processing 2 is performed before stopping the operation of the MCPU 26 and after stopping the operation as in step S3.
The CPU 26 sets conditions for restarting the operation. In the standby process 2, the operation is set to start by a change of a switch linked to the operation button. That is, when the operation button on the operation device is pressed and a start signal is generated through the line STAN, When the zoom or release button is pressed, the power switch 1 or the back cover switch 5 changes. Then, the operation of the MCPU 26 is stopped. When the standby is released, the subroutine "MCPU main" is executed from the beginning.

Next, the operation of the SCPU 46 on the operation device side will be described with reference to the flowchart of FIG. When a power supply (battery) is loaded into the operation device, the SCPU 46 starts operating, and the main routine “SCPU main” is called.

In step S32, a process associated with an operation on the operation device is performed.

That is, when the STSW 48 is pressed, the strobe mode is sequentially changed, and the display changes from "auto mode" (no display) to "red-eye mode" (segment 18) → "strobe flash mode" (segment 19) → "segment". The display is scrolled in the order of “flash stall mode” (segment 19) → “night scene shooting mode” (segment 20) → “auto mode” (no display). The state of this mode is SCP
