PURPOSE:To make a special signal means on the power supply device side unnecessary by using the output of a brake circuit on the power supply device side as a signal which transmits whether the power supply device side is set for continuous photographing or one-frame photographing. CONSTITUTION:When a release button is depressed in the state, where film idle feeding is terminated, to close a release switch S1 for the purpose of performing one-frame photographing, a motor starts the rotation for shutter release, and a movable reflective mirror rises, and a camera switch S2 is switched to the side of an up terminal up. Then, the output of an inverter N3 attains to low-level, and the output of an NAND gate A15 is returned to the high level. Then, the output of an NAND gate A17 attains to low-level, and the output of an inverter N32 becomes high-level, and power supply to the motor is broken, and the brake circuit is operated for a certain time to stop the rotation of the motor. A motor switch S6 is switched to the side of a winding terminal (a) approximately simultaneously with the rise of the movable reflective mirror, and the output of an NAND gate A14 becomes high-level. |
