摘要： A head-mounting plate is movable between a latched play position, a standby position and a withdrawn position. The plate is moved from the play to the standby positions when the end of the tape is reached or when an actuating rod is depressed slightly. The rod has a guide slot for unlatching the plate, and a switching surface for a tape transport drive switch. A pivotal member on the plate clears the drive switch when in a first pivotal position, and opens the switch during return of the plate to the standby position when in a center position. Upon re-depression and movement of the rod in a specific direction, a stop on the rod moves the member to the first pivotal position. After this re-depression the switch is closed during return movement of the rod in the opposite direction, and a servomechanism moves the head plate from the standby to the play positions.
摘要翻译：头部安装板可在锁定的游戏位置，待机位置和撤回位置之间移动。当磁带的末端到达时或当致动杆被轻微按下时，将板从播放件移动到待机位置。杆具有用于解锁板的引导槽和用于带传送驱动开关的切换表面。当板处于第一枢转位置时，板上的枢转构件清除驱动开关，并且当处于中心位置时将板返回待机位置时打开开关。当杆沿特定方向重新按压和移动时，杆上的止动件将构件移动到第一枢转位置。在这种重新按压之后，开关在杆的相反方向的返回运动期间关闭，并且伺服机构将头板从待机移动到游戏位置。
