<p>PURPOSE:To let sure automatic stopping be performed without malfunction by controlling the actuating member which releases the locking of an operating member and detects running and stopping by way of a rotating body which cooperates with a flywheel nonsynchronously. CONSTITUTION:An actuating member 18 is oscillated by the rest pin 17 which is contacted with the cam 15 of a rotating body 14 by being pressed by a rotating body 12 actuating cooperatively with a reel turntable 10 by way of a friction member 11. This causes a supporting member 19 to be turned, by which the stopping member 24 moving on the rotating track of the protrusive stopping part 22 of a flywheel 21 is oscillated. When the turntable 10 stops at the tape end, the lock member 30 of playback button is unlocked by an unlocking mumber 29, by which running stop state is set. The running stop is then detected and resetting to the initial condition of a stop detector by a resetting member 20 is accomplished with a slight delay. In this case, the wheel 21 and the rotating body 12 turn nonsynchronously at a non-integer ratio, whereby the effect of the minute oscillation deviations of the member 18 is eliminated.</p> |
