<p>PURPOSE:To allow simplification of a mechanism and its miniaturization by making either of a fast feeding operation lever and a rewinding operation lever return to the nonoperational position when a forward/reverse switching means changes from the forward condition to the reverse condition. CONSTITUTION:When a right switching operation lever 10 is operated with pressure in the forward reproduction condition, the forward mode is switched to the reverse mode. In other words, when the direction switching operation lever 10 is operated with pressure, a cam lock arm 38 is rotated by the prescribed angle in the clock-wise direction around a supporting shaft 62 by a cam lock arm operation piece 37 of the operation lever 10. Thus, a right-side engaging piece 51b of a latch plate pin 51 is removed from the right-side engaging part, and it is guided to the rear part of an engagement guiding hole 55. An engaging lock protrusion 66 and an engaging protrusion 74a of the other are disengaged. A cam gear 59 is energized by the spring (not shown in the figure), it rotates in the counterclockwise direction, and it meshes with a driving gear 75. Thus, even a part without gear tooth 73b is rotated by the driving gear 75.</p> |
