<p>PURPOSE:To prevent an automatic stopping mechanism from operating unnecessarily by providing an automatic stopping mechanism assembly which returns an operating member to a stop position by the power of a motor on detecting the run stop of a tape. CONSTITUTION:When a tape comes to its end and right reel turntable 31 stops, a detection lever 180 returns to a solid-line position by being released from the pressure of a friction plate 608. Consequently, the projection 603 of a cam wheel 601 rotates to engage with a pin 181a, and the detection lever 180 moves to an upper part in the figure to rotate a selector lever part 293 clockwise through a lever 190 and a spring. Then, a small gear 802 meshes with a large gear 213, and a resetting gear 200 with which the lower small gear 211 of a gear 210 and a gear 221 are engaged is rotated counterclockwise. Consequently, the pin 222 of the resetting gear 220 while rotating engaged with a lock plate 11, which is moved to left to reset a prescribed operation element in a locked state to its original stop state, thus completing automatic stopping operation entirely.</p> |
