Filed: 1983-06-07
Abstract: PURPOSE:To reduce the consumption of a battery by holding a receiving circuit in a holding state with an external light which a photodetector of the receiving circuit of a remote control device set to a camera receives. CONSTITUTION:When an external light is made incident to a photodetector SP during holding, a capacitor 1 is charged up to the output voltage of the photodetector SP, and a transistor TR Q1 is made conductive, and a TR Q2 is cut off. When the light of an operation command signal is made incident to the photodetector SP, the output of the photodetector SP is increased quickly, and the TR Q2 is made conductive, and therefore, a TR Q11 is made conductive to supply power to a control circuit C, and a TR Q12 is made conductive to hold the TR Q11 in the conduction state. Consequently, the consumption of a battery E is reduced because the receiver consumes hardly the current during holding.
