Coupling device for radio set and small size tape recorder

摘要

A coupling device for detachably coupling a radio set and a miniature tape recorder includes a pocket formed in one lateral side of the radio set so as to be displaceable between a first and a second position. A group of terminals are provided in the pocket for an electrical connection with another group of terminals formed in the tape recorder so that the electrical circuits of the both units are connected together automatically when the recorder is mounted in the pocket, thereby enabling transfer of an electrical signal therebetween. The coupling device also includes a switch which is physically mounted on the recorder and which is responsive to an operation of a record/playback button, the switch being connected through the groups of terminals to act as a power switch in the electrical circuit of the radio set. Another switch is provided in the radio set and is responsive to a displacement of the pocket between the first and the second position to control the operation of a recording microphone which is internally housed within the recorder.
