    • A video cassette with two reels which are arranged in plane-parallel fashion for winding and unwinding a magnetic tape and with a locking mechanism consisting of a pivotal two-armed pawl for each reel which can be slipped on a support. One lever arm engages in a toothed reel flange in the inoperative position of the cassette and the other lever arm rests on the disengaging component of a vertically rotatable release lever. The locking mechanism also includes moulded pre-tensioning arms, the deflection points of the pre-tensioning arms rigid with the housing at the support lie close to the rotational axis of the pawl.
    • 具有两个卷盘的盒式录像带,其以平行平行的方式布置,用于卷绕和展开磁带,并且具有锁定机构,该锁定机构由每个卷轴上的可枢转的双臂爪构成,该棘爪可以滑动在支撑件上。 一个杠杆臂在磁带的非工作位置处接合齿形卷轴法兰,另一个杠杆臂搁置在可垂直旋转的释放杆的分离部件上。 锁定机构还包括模制的预张紧臂,预拉伸臂的刚性与支撑件处的壳体的偏转点靠近棘爪的旋转轴线。
