摘要： A magnetic recording/playback apparatus in which rotational torque from the drive shaft of a single motor is capable of being transmitted to a cassette loading mechanism and a tape loading mechanism includes a worm secured to the drive shaft and a worm wheel for being meshed freely with the worm, the worm wheel being provided with a toothless portion. The drive shaft is coupled to the cassette loading mechanism via the worm wheel. During operation of the tape loading mechanism by the drive shaft, the toothless portion of the worm wheel is brought into position opposite the worm wheel so that a driving force is no longer applied to the cassette loading mechanism. When a cassette is ejected, the toothless portion of the worm wheel is shifted after a tape loading operation, thereby re-­engaging the worm wheel and worm to actuate the cassette loading mechanism.

摘要翻译： 一种磁记录/重放装置，其中来自单个电动机的驱动轴的旋转扭矩能够传递到盒装载机构，并且带装载机构包括固定到驱动轴的蜗杆和用于与自动啮合的蜗轮， 蜗杆，蜗轮设有无齿部分。 驱动轴通过蜗轮联接到盒装载机构。 在通过驱动轴操作带子装载机构期间，蜗轮的无齿部分进入与蜗轮相对的位置，使得驱动力不再施加到盒装载机构。 当盒子被弹出时，蜗轮的无齿部分在带装载操作之后移动，从而重新接合蜗轮和蜗杆以致动盒装载机构。
