Abstract
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.
