CONSTITUTION:When the microphone unit 8 fitted to a part of the case 7 of the electronic instrument attachably/detachably is slid in the arrow B direction toward the outside of the case 7, a terminal 11 is disengaged from a jack 16 of the case 7 and the power supply circuit is interrupted and turned to the temporary stop status. On the other hand, connection terminal 17a, 17b arranged in the jack 16 fixed in the case 7 and connected to the microphone circuit in the electronic instrument through a lead wire 18 are contacted with microphone terminal 12a, 12b and the microphone is actuated. When power supply connection terminals 19a, 19b connected to the power supply circuit through a lead wire 20 are contacted with power supply terminals 13a, 13b, electric power is supplied to the electronic circuit.</p> |
