摘要:
本发明既可削减用于接收遥控信号的受光元件的功耗又可削减用于控制受光元件的微型计算机的功耗. The present invention can reduce power consumption for receiving the remote control signal light-receiving element can be used to reduce power consumption of the microcomputer control of the light-receiving element. 本发明的微型计算机(10)由驱动电路(11),取样/检测电路(12),计时器(13),系统时钟生成电路(14),CPU(15),ROM(16),RAM(17)构成. The microcomputer of the present invention (10) by a driving circuit (11), the sampling / detection circuit (12), a timer (13), the system clock generation circuit (14), CPU (15), ROM (16), RAM (17 ) form. CPU(15)通过驱动电路(11)使P沟道型MOS晶体管(22)截止来停止对受光元件(21)的电源供给,并且,将微型计算机(10)仅在规定时间设定为待机状态. CPU (15) through the drive circuit (11) so that P-channel type MOS transistor (22) off to stop power supply to the light-receiving element (21) and the microcomputer (10) only for a predetermined time is set to standby . 在微型计算机(10)的待机状态被解除时,通过驱动电路(11)使P沟道型MOS晶体管(22)导通来开始进行对受光元件(21)的电源供给. When the microcomputer (10) standby state is released by the drive circuit (11) so that P-channel type MOS transistor (22) is turned to the start of the subject (21) of the optical component power supply.
