Abstract
A camera power source control device comprises a press switch and a mechanical start switch. The press switch is disposed on one circuit located between the camera power source and a zoom cylinder control motor such that the circuit is connected at the time when the press switch is pressed, thereby driving the control motor to extract the zoom cylinder to locate at a predetermined position. The circuit is disconnected when the press switch is not pressed. The mechanical start switch is disposed on other circuit located between the camera power source and the zoom cylinder control motor and is formed of a first contact electric piece and a second contact electric piece, which are separated from each other at the time when the zoom cylinder is retracted to a closed position. The two contact electric pieces are in contact with each other at the time when the zoom cylinder is extracted to locate at a standby position.
