AUDIO DEVICE
Document Type and Number:
Japanese Patent JPS5916184
Kind Code:
A
Abstract:
PURPOSE:To switch modes of an amplifier and a tape recorder to record input and output recording running respectively if a record player is operated when the tape recorder is in the recording holding state, by connecting a switching control means of the record player, a switching control means of the tape recorder, and a switching control means of the amlifier through an auxiliary switching control circuit. CONSTITUTION:When a switch 15 for recording of a tape recorder 10 is depressed to set the recording holding state, a conductive transistor (TR) 54 becomes nonconductive and TRs 56 and 58 are held in the conduction state because a recording display terminal 26 is connected to the earth. Next, when a switch 4 for start of a record player 1 is depressed to set the reproducing state, electric power is supplied to a diode 51 because a fall signal terminal 7 is connected to the earth, and a selecting circuit 36 is switched to record input by a switching control circuit 50, and simultaneously, the TR56 is made conductive, and a switch 17 for reproducing on the tape recorder 10 set to the recording holding state is turned on, and the tape recorder starts recording running.
