摘要： In exposure means comprising, in combination, two shutter blades which also function as the aperture setting blades, a step-motor for displacing the shutter blades stepwise in response to the driving pulse or pulses, and a driving circuit for the step-motor. Slits are cut through the shutter blades so that the relative displacement between the shutter blades may be optically detected in order to control the stepwise rotation of the step-motor, thereby displacing the shutter blades to define the main aperture stepwise; and when the light from a subject reaches a predetermined level, detecting means causes the step-motor to reverse its rotation, thereby closing the shutter blades. The program-controlled shutter in accordance with the present invention is very simple in construction and is free from any erratic operations.

摘要： In response to the film drive control pulse signal generated when the shutter is closed, a switching circuit is turned ON to energize a film driving motor. When the film has been transported by a predetermined length, another control signal is generated to turn OFF the switching circuit. A control circuit is connected to a control circuit for controlling the shutter and to a circuit for controlling the motor in such a way that in response to the multi-exposure mode signal the control circuit will not energize the motor even when the pulse signal has been generated after the exposure. Thus the camera control device offers versatile multi-exposure operation.
