Abstract
PURPOSE: To eliminate the laboriousness of switch operations by connecting the electric circuit on the camera body side to a motor drive side power source by way of a changeover member at the closing of a motor drive device side power source switch.
CONSTITUTION: If an operating member 7 is set at the ON position in the case of performing photographing through automatic film winding by closing a switch 13, a switch piece 2a is pushed to close the power source switch 2 of a motor drive device 1. This also causes a changeover member 9 to be pushed against a spring 11 by its cam face 7a, causing the switch piece 4a to be pushed by the leading end thereof and to be detached from the switch piece 4b thereby opening the power source switch 4 of the camera body 3. As a result, the electric circuit 5 on the body 3 side is put in the working state through the member 9 and switch piece 4a by the power source 6 on the device 1 side, and the power source 12 of the body 3 side is cut off. Thereby, the laboriousness of the switch operation on the way of photographing is eliminated.
