<p>PURPOSE:To stop quickly the rotation of a reel shaft when a head is separated from a tape, by separating a pair of gears, which constitute a clutch mechanism, from each other quickly when a head attaching member is moved backward. CONSTITUTION:The first moving member 25 is supported freely turnably on a shaft 24 of a substrate, and switching gears 26 and 27 are attached to this member 25. The second moving member 31 is provided freely turnably on a reel shaft 2b, and an idler gear 32 is attached to it. The clutch mechanism is constituted of gears 27 and 32, and the directions in which gears 27 and 32 are separated from each other intersect the line connecting centers of gears. When a head attaching part 5 is moved backward, the first and the second engaging parts 6 and 7 are engaged with moving members 25 and 31, and they are turned counterclockwise, and gears 27 and 32 are separated from each other quickly, and a driving motor 18 is stopped by a prescribed switch. Thus, the reel is stopped quickly when the head is moved backward.</p> |
