IPC: G03B17/02
Filed: 1986-04-19
Abstract: PURPOSE:To prevent batteries from being wasted by judging that a power source is left on forgetfully when camera operation is not performed at all within a constant time and turning off the power source automatically. CONSTITUTION:When a main switch 10 is turned on and a capacitor is charged up to a specific potential, a transistor (TR) 13 turns on and a switching circuit 15 enters an ON state to feed electricity from a battery 14 to a control circuit 30, etc. If the camera is left as it is with the switch 10 ON, the output terminal D of a counter 22 goes up to an H level a specific time later unless the camera is mounted on a tripod and camera operation is performed within the specific time. When the terminal D goes up to the H level, a nonuse signal is inputted to the control circuit 30 through an OR circuit 41. Consequently, respective mechanisms of the camera are set in an unuse state. A delay circuit 16, on the other hand, delays the nonuse signal by the time for which the camera is placed in the unuse state and sends the signal to the circuit 15. Consequently, the circuit 15 turns on respective electric circuits connected to a power line L.
