Electric power supply control device for camera |
摘要 |
The power supply in a camera is connected to the camera control section only through a normally-off switch which is rendered conductive only when a switch is operated requesting that as camera control function be performed. The power supply is connected to the function request switches at all times, but only in a high impedance state so that there is substantially no power consumption when the camera is not actually operating.
