<p>PROBLEM TO BE SOLVED: To secure brake precision, to miniaturize a device and to reduce a cost by stopping rotation of a middle gear fixing its rotary central shaft, engaged with a tape feeding gear held rotatably and made movably and transmitting drive force with a stop member. SOLUTION: A tape take-up idler gear 16 always engaged with an R round- stop gear 17 integrally formed with a tape feeding reel shaft 7b and fixing its rotary central shaft is provided, and the rotation of the RA gear 16 is stopped by a brake mechanism constituting with a brake lever 20, etc. At this time, the turning amount of the brake lever 20 is reduced than brake operation for the R round-stop gear 17 since the rotary central shaft of the RA gear 16 is fixed, and a space required for a movable member constituting the brake mechanism is reduced. Further, by engaging the engagement pawl part 20b of the brake lever 20 with the RA gear 16, the brake precision is secured precisely.</p> |
