<p>PURPOSE:To make it needless to hold always a solenoid in a turning-on state by providing a mechanical lock mechansim in the tape recorder where the electromagnetic force of the solenoid, etc., is utilized to move a sub-chassis equipped with a head, etc., to the play-state position. CONSTITUTION:When solenoid 23 is excited temporarily, side part 22d of hole 22c of sub-chassis shift lever 22 is pressed to rotate lever 22 in the clockwise direction, and sub-chassis 18 whose stop is released by the insertion of a cassette is moved to the play position. Simultaneously, lock plate 24 is moved to the left by pin 22b of lever 22, inclined part 24b of play lock plate 24, etc., and play lock release plate 27 is rotated. When the solenoid is demagnetized under this state, lever 27 whose stop is released by solenoid pin 23b is rotated by the elastic force of spring 25, and protrusion part 27b is linked with pin 24d of lock plate 24 to stop lever 22 through lock plate 24, and sub-chassis 18 becomes a reproducing state also after excitation break of solenoid 23.</p> |
