<p>PURPOSE:To improve the fast forward/rewind performance of a cassette tape recorder by providing a collar having a lock member slidably to a reel rotary shaft to energize the rotary shaft in the axial direction via a sleeve with pressure applied to the collar. CONSTITUTION:A reel collar 25 having a lock member 27 is fitted to a reel rotary shaft 19 with a play via a coil spring 26, and a reel sleeve 23 having a structure similar to the collar 25 is fitted to the lower part of the collar 25 with a play. While the fast forward and rewind operators are provided to a front cabinet. When the fast forward operator is pressed in a reproduction mode shown in the figure, the collar 25 and the sleeve 23 are shifted toward the axial direction. Thus the member 27 is locked by a hook lever 28. At the same time, gears 22 and 30 are disengaged from each other and gears 22 and 31 are engaged with each other to secure a fast forward mode. In this case, the shaft 19 is protruded by a space A and the fast forward mode is confirmed. In such a way, the fast forward/rewind performance is improved for a cassette tape recorder.</p> |
