<p>PURPOSE:To make constitution simple and permit cue operation, etc. by detaining the cam or stopper of the mode change-over gears meshed with a capstan gear to trigger levers thereby setting the play or reset state. CONSTITUTION:A magnetic head 9 is fixed to a head base 7 and is slided forward and backward by a dumping plate 8. FD, FR trigger gears 21, 22 mesh with a capstan gear 15b, and FD, FR, cam gears 23, 24 mesh with these. When a lever 18 is operated by the play signal from the reset state that stoppers 26, 28 are held detained to trigger levers 18, 20, the gears 21, 23 revolve and in the place of a notched part 21a, they are strongly pulled by a spring SP3, then a cam 23a forces a cam block 8a upward, thereby allowing the head 9 to abut on the tape and cam 25 to be detained by the lever 18. When the lever 20 is operated in this play state, the cam 24a forces a base 7 downward by the operation similar to the above, thereby weakening the press-contact force of the head 9 and permitting cue operation, etc. Thereby, the constitution is made simple, and the cue operation etc. are made possible.</p> |
