CONSTITUTION:For switching a tape travel direction by operating the switching lever 28 by a direction switch-operating lever 30, the switching lever 28 is operated at the prescribed hourly intervals when the direction switch-operating lever 30 is operated. In such a case, the shutting-off lever 38 is pressed by the direction switch-operating lever 30 and detached from the switching lever 28 before action. Consequently, the shutting-off lever does not turn, and the shutting-off action of a lock plate 42 is prevented. Thus, the shutting-off malfunction of the play lever 16 is cancelled when the tape travel direction is switched.</p> |
