ABSTRACT:
A coupling device comprises a pair of coupling channels formed in the both lateral sides of a compact cassette tape recorder, and a pair of rails formed on a part of a radio set for engagement with the channels, allowing the cassette tape recorder to be detachably coupled with the radio set. When not coupled, apertures provided in the tape recorder for connection terminals are covered by a coverplate, which uncovers these apertures by a sliding movement as the tape recorder is coupled with the radio set, thus enabling an electrical connection with the latter. The compact tape recorder can be detachably coupled with an accessory unit such as a tuner, a microphone pre-amplifier or the like by a single mounting threaded stud.
