摘要： A tape cassette which can be recorded and played back on both sides or in opposite directions has a lid having a pair of side arms pivotally mounted on lateral sides of a cassette casing for opening and closing a front opening in the cassette casing. The lid is normally held in a closed position by means of springs which normally urge pivot pins on the side arms toward a rear side of the cassette casing. The tape cassette also has protective plates integrally projecting in a forward direction from the lateral sides of the cassette casing in covering relation to the side arms, respectively. The protective plate protects the side arms against intentional or accidental engagement with a finger or a cassette recorder, thereby preventing the lid from being easily opened. The cassette recorder for use with the tape cassette includes abutments for engaging distal ends of the protective plates for accurately positioning the tape casette as inserted in the cassette recorder.

摘要翻译： 可以在两侧或相反方向上记录和回放的盒式磁带具有盖，其具有一对侧臂，该侧臂可枢转地安装在盒壳体的侧面上，用于打开和关闭盒壳体中的前开口。 盖子通常通过弹簧保持在关闭位置，弹簧通常沿侧臂的枢轴朝向盒壳体的后侧推动。 盒式磁带还具有分别从盒式磁带盒的侧面向前方整体地突出的保护板，其与侧臂相对地覆盖。 保护板防止侧臂与手指或盒式录像机有意或意外接合，从而防止盖容易打开。 用于带盒的盒式录像机包括用于接合保护板的远端的抵接件，用于将插入盒式录音机中的带盒精确地定位。
