Abstract: A cartridge locking mechanism for a tape player having a tunnel for receiving a tape cartridge, comprises a pivotally mounted arm having a projection extending into the tunnel in the path of a cartridge received therein. A torsion spring mounted for rotational and torsional movement adjacent the tunnel includes a first end extending outwardly therefrom for engagement with the actuator arm. The second end of the spring extends outwardly toward the cartridge receiving tunnel and includes a roller for receipt in a groove in a side wall of the cartridge. When inserted into the tunnel, the cartridge engages the projection, causing the actuator arm to rotate. Rotation of the arm in turn rotates the torsion spring, thereby to move the roller into the tunnel in engagement with the cartridge in the groove therein. Full insertion of the cartridge into the tunnel ''''twists'''' the torsion spring, providing a force at the roller directed against the tape cartridge to maintain the latter secured in the tunnel.

Abstract translation: 用于具有用于接收带盒的隧道的带式播放机的盒式锁定机构包括枢转安装的臂，其具有在容纳在其中的盒的路径中延伸到隧道中的突起。 安装用于邻近隧道的旋转和扭转运​​动的扭转弹簧包括从其向外延伸的第一端，用于与致动器臂接合。 弹簧的第二端朝向药筒接收通道向外延伸，并且包括用于容纳在药筒的侧壁中的凹槽中的辊。 当插入隧道时，盒与突起接合，致使执行器臂旋转。 臂的旋转又使扭簧旋转，从而将辊移动到通道中，与槽中的槽接合。 将盒子完全插入隧道中以“扭转”扭力弹簧，从而在辊子处提供力，以抵抗磁带盒以将其固定在隧道中。
