ABSTRACT:
A fast forward and reverse drive mechanism is disclosed, which comprises a fast drive link having a fast drive pin disposed at one end and supported rotatably by a pivot shaft at its center portion; a mode plate moving in the left and right directions; a fast forward drive lever and a reverse drive lever superposed on each other and locking the fast drive pin either at the forward side or the reverse side by pushing either one of the levers; two fast drive arms disposed rotatably at both sides of the fast drive link, each having a fast drive shaft at an extremity; guide holes formed at the left and right sides in the mode plate; the fast drive shaft being engaged through these guide holes with the mode plate so that the fast drive shaft moves left and right depending on left and right displacement of the mode plate; and guide holes, each of which consists of a press portion and a slide portion at its left and right sides, formed in the fast forward drive lever and the reverse drive lever, respectively, the guide holes of one of the levers, both at the left and right sides, having press portions at their inner side and slide portions at their outer side, the guide holes of the other having press portions and slide portions respectively at their outer and inner sides; said left and right fast drive shafts being inserted in these guide holes so that the fast drive shaft is located either at the press portions or the slide portions depending on displacement of the fast drive shaft in the left and right directions.
