<p>PURPOSE:To make the operation of a reproducing button light and to make a mechanism small in size and light in weight by displacing a stroke from a position just before the press-contact between a pinching roller and the shaft of a capstan is started to a tape constant speed traveling position where it is finished with the aid of a power assist mechanism by a cam gear. CONSTITUTION:A range where a head substrate 62 is manually displaced is set from a stop state to a cue/review position where a magnetic head is merely brought into contact with a tape. Then, the stroke from the position just before the press-contact between the pinching roller and the shaft 2 of the capstan, which makes operating force heavy, is started to the tape constant speed traveling position where it is finished, is displaced by the power assist mechanism by the cam gear 8. Thus, the operation of the reproducing button is made light and the displacement quantity of the power assist operation by the cam gear 8 is reduced, besides. As the result, the mechanism is made small in size and light in weight.</p> |
