Abstract

PURPOSE:To simplify the constitution of a circuit and to reach a cost by selecting the mechanism of one side and, simultaneously, fixing the muting output of the control means of the mechanism of the other side at a low potential. CONSTITUTION:The constitution is made in which two sets of mechanisms 1 and 2 are operated by switching by means of a pair of operating switches 9 and 10, either set of the mechanisms 1 and 2 is operated, and simultaneously, they are controlled by control means 3 and 4 such as a microcomputer and a gate circuit exclusive-use for respective mechanisms. Consequently, the muting outputs of two pairs of the control means 3 and 4 can be combined through a diode and directly supplied to a transistor for muting a signal output. Namely, since the muting output of the side in which action is not selected is fixed at the low potential, the action is executed so as to control the muting only by the control means 3 and 4 of the operated side. Thus, the complexity of the circuit and the expensiveness of the cost can be prevented.
