    • A cassette tape loading and ejecting mechanism in a tape player for playing back tapes using a driving force of a main motor. The mechanism includes a sun gear provided in part of a mechanism for transmitting the driving force of the main motor. A stationary ring gear is arranged coaxially with the sun gear. A carrier is mounted on a shaft coaxially with the sun gear and is engaged by friction with the sun gear. A planet gear supported by the carrier engages the sun gear and the ring gear. A slot-in type tape cassette holder is driven by the forward and reverse rotation of the carrier for loading and ejecting tape cassettes. The planet gear engages the ring gear when the main gear when the main motor rotates forwardly and the carrier is caused to turn forwardly whereby the planet gear is positioned opposite to an untoothed portion of the ring gear after a tape cassette is loaded and the carrier then stops to allow the playback of the tape continuously. The planet gear again engages the ring gear when the main motor rotates reversely and the carrier turns reversely to cause the tape cassette to be ejected.
    • 一种用于使用主电动机的驱动力回放带的磁带播放机中的盒式磁带装载和排出机构。 该机构包括设置在用于传递主电动机的驱动力的机构的一部分中的太阳齿轮。 固定环形齿轮与太阳齿轮同轴设置。 载体与太阳齿轮同轴地安装在轴上,并通过与太阳齿轮的摩擦接合。 由承载件支撑的行星齿轮啮合太阳齿轮和环形齿轮。 插入式带盒保持器由用于装载和弹出盒式磁带的托架的正向和反向旋转驱动。 当主电机向前旋转并使托架向前转动时,行星齿轮与主齿轮接合,由此行星齿轮在装入带盒后位于环形齿轮的未旋转部分的相对位置,然后载体 停止以连续播放磁带。 当主电机反向旋转时,行星齿轮再次啮合齿圈,并且载体反向转动,导致磁带被弹出。
