<p>PURPOSE:To improve the reliability of a tape loading action by driving a brake releasing means with a reel driving motor and releasing an idler gear with an idler releasing member. CONSTITUTION:While a driving gear 1 is further rotated, an intermittent gear 2 is rotated one time and arrives at the intermittent position, a locked part 2a of the intermittent gear 2 is locked to a locking part 6b of a brake releasing lever, as the result, the intermittent gear 2 is energized to the intermittent position and a reel brake releasing action is completed. When a tape loading command is executed and a tape loading gear (not shown in the figure) is rotated, a kicking arm 18 is pulled in the left downward direction by this gear, as the result, an idler locking arm 12 is turned in the counter-clock-wise direction which is a releasing direction, a lock released idler releasing lever 13 is turned in the colck-wise direction with the energizing force of an idler releasing spring 15, an idler gear 16 is shifted at the central position and opened from a reel base 17L. Thus, since the releasing of a reel brake is executed by a reel driving motor, a tape loading driving system can be facilitated.</p> |
