Claims

[Claim for Utility Model Registration] When the power switch is turned on and the playback button is pressed, the playback button is held mechanically, which turns on the play switch and energizes the tape drive motor and the recording/playback circuit, causing the tape drive motor and recording/playback circuit to be energized. In a tape recorder configured so that when the tape reaches its final end, the playback button automatically returns and the play switch turns off. a series circuit connected in parallel to the output and consisting of a play switch, a tape drive motor, and a switching element;
The switch includes a recording/reproducing circuit connected in parallel to the output of the DC power supply circuit via a power switch, and a drive circuit that closes the switching element when the power switch is turned on. A tape recorder characterized by maintaining a closed circuit state until the circuit is turned off.
