プレコーダの電源回路。 A timer circuit that generates a timer output signal at a set time and generates different operating signals depending on whether the time is set or not, an opening/closing transistor that is turned on and off by the operating signal from the timer circuit, and the timer circuit. A control transistor controlled by a timer output signal generated at a set time or a switching transistor, a power supply and a radio
a first power transistor connected between the amplifier circuits and turned on by the control transistor; a second power transistor connected between the power supply and motor circuits and turned on by the control transistor; It consists of a changeover switch that supplies only one power supply transistor or the first power supply transistor and the second power supply transistor via a motor switch, and when the time is not set, the open/close transistor is turned off by the operation signal from the timer circuit, and the control transistor is always biased. Supplying current, turning on the first power transistor or the first power transistor and the second power transistor by operating the changeover switch and motor switch, and turning on the control transistor by the timer output signal from the timer circuit when setting the time. 1. A power supply circuit for a tape recorder with a radio, which turns on a first power transistor or a first power transistor and a second power transistor.
