    • A mode selecting assembly for a recording and/or reproducing apparatus includes at least one operating member, which is displaced to change the apparatus over to an operating mode. The operating member is displaced by the revolution of an operating gear having a toothless portion and the operating gear is driven by a pinion. The engagement of the operating gear with the pinion is triggered by a trigger member responsive to the depression of a corresponding operating push button. The operating gear is prevented from further rotation after the establishment of the selected operating mode by a locking member when the selected operating push-button is continuously depressed. The mode selecting assembly further includes timed recording capability wherein the pinion in engagement with the end of the toothed portion of the operating gear maintains the trigger means in an inactive state to place the apparatus in a preparing mode for timed recording. At the preset time, the preparing mode is released by a releasing member and the operating gear is rotated to its original inoperative position where the toothless portion faces the pinion to disengage the operating gear from the pinion.
    • 用于记录和/或再现装置的模式选择组件包括至少一个操作构件,其被移动以将装置改变为操作模式。 操作构件通过具有无齿部分的操作齿轮的旋转而移位,并且操作齿轮由小齿轮驱动。 操作齿轮与小齿轮的接合由响应于对应的操作按钮的按下的触发构件触发。 当所选择的操作按钮被连续按压时,通过锁定构件建立所选择的操作模式后,防止操作齿轮进一步旋转。 模式选择组件还包括定时记录能力,其中与操作齿轮的齿形部分的端部接合的小齿轮将触发装置保持在非活动状态,以将装置置于用于定时记录的准备模式。 在预设时间,通过释放构件释放准备模式,并且操作齿轮旋转到其无齿部分面向小齿轮的原始非工作位置,从而将操作齿轮与小齿轮分离。
