Abstract

PURPOSE:To reduce the number of connectors and the number of pins and to miniaturize equipment by switching the role of respective pins of a connector in accordance with the type of connected acoustic equipment. CONSTITUTION:In accordance with the equipment connected to the connector 11 of a tape deck, a signal inputted and outputted through respective pins PA1-PA13 is switched. When a tuner and an amplifier are connected to a deck, selectors S1-S13 are set to an (a) side, the PA1-PA3 become the signal input terminal from a tuner, PA4-PA8 become a terminal for a control signal between a microcomputer 23 of the deck and the microcomputer of the turner and PA9-PA13 go to the output terminal and control terminal to the amplifier. When the S1-S13 are switched to a (b) side or a (c) side, respectively, PA1-PA5 and PA9-PA13 become the output terminal and control terminal to respective amplifiers PA1-PA3 and PA12 and PA13 become a key signal input terminal, PA4-PA8 go to the terminal for a control signal between the microcomputer 23 and the microcomputer of an adapter for home and PA9-PA11 become the output terminal to the amplifier.
