Abstract

PURPOSE: To perform multiple exposure photographing effectively by providing a switch for setting multiple exposure times and a display device.
CONSTITUTION: A display device is connected via display decoder 116 to a subtraction counter 117 which is connected with a release switch 108 via flip-flop circuit 113, etc. Also, a digital switch 118 for setting multiple exposure times is connected thereto. Then, when the weight of exposure of each time in the desired exposure times and multiple exposure is set in the switch 118 and variable resistance 132 and the switch 108 is turned ON, then the set contents are set in the subtraction counter 117 and are displayed in the display device 115. Also, power supply to a shutter drive coil 114 is accomplished, by which the shutter is opened. Thence, if the second exposure is set in the variable resistance 132 and the operations are done similarly, the second exposure is accomplished and the display contents of the subtraction counter 117 and display device 115 are subtracted.
