<p>PROBLEM TO BE SOLVED: To make the device miniature and thin structure by simplifying an automatic stopping mechanism. SOLUTION: This device is equipped with a reel driving mechanism part for rotationally driving a take-up side reel base 7 and a supply side reel base 8, a reproducing operation lever, a fast forward operation lever 33 and a rewinding operation lever 34 to be performed by a push-in operation, a lever lock slider 38 for locking these operation levers under their push-in state, a torsion coil spring 125 to be rotated integrally with the take-up side reel base 7 and a cam gear 22 with a cam part 22c and an engagement projected part 22d to be rotated by the reel driving mechanism. Then, the device is equipped with a shut-off lever 37 provided freely oscillatably and having a cam arm part 128 to be abutted against the cam part 22c of the cam gear 22 and also engaged with the engagement projected part 22d, an oscillating operation part 127 to be oscillated by the torsion coil spring 125 and an operation part 129 for operating the lever lock slider 38 to move.</p> |
