ーダーの制御回路。 A tape recorder with a radio that has a built-in radio receiving circuit and uses a battery as a power source includes a timer circuit operated by a clock battery provided separately from the battery, and an output signal of the timer circuit. A trigger transistor that becomes conductive for a short time when the trigger transistor is turned on, and a power supply that is reversed to a conductive state by the conduction of the trigger transistor and supplies power from the battery to the radio receiving circuit and tape recorder circuit when it is in the conductive state. a transistor; a holding transistor that becomes conductive by inverting the power supply transistor to a conductive state and maintains the power supply transistor in a conductive state;
an operating circuit that is operated by the output signal of the timer circuit and outputs a switching signal to put the tape recorder in a recording mode; and an operating circuit that is connected to control the operation of the holding transistor and that detects the end of the magnetic tape. and a control transistor that becomes conductive and inverts the holding transistor to a non-conductive state during the accompanying return operation to the stopped state, and inverts the power supply transistor to a non-conductive state by inverting the holding transistor to the non-conductive state. 1. A control circuit for a tape recorder with a radio, characterized in that the power supply to the radio receiving circuit and the tape recorder circuit is cut off.
