Abstract

PURPOSE:To minimize the number of operations of an antenna, by elevating the antenna, only when both radio and radio/cassette operating signals are outputted from a switch circuit to an up/down control circuit. CONSTITUTION:An up/down control circuit 24 inputting a radio operation signal 100 and a radio cassette operation signal 102 is provided with a relay 38 elevating an antenna with the input of the signal 100 and a relay 40 falling down the antenna, and a relay driving circuit 52 driving the relay 40 outputs a relay driving signal only when the signal 102 is not inputted from a switch circuit 26 through the switching operation of a transistor 50. Switches 14 and 16 are interlocked with the operation of the relays 38 and 40 and the switches 14 and 16 are closed when contacts 46 and 48 are selected to the right position. Thus, only when both signals 100 and 102 are outputted at the same time to the circuit 24, the antenna is elevated and when the signals are not outputted at the same time, the antenna is fallen down.
