<p>A cassette tape player includes a cassette carrying mechanism which conveys a cassette tape between the insertion position and the hold position of the player automatically, a mode selection lever which reciprocates depending on various operational modes, and a drive motor which drives the cassette carrying mechanism and the mode selection lever, a lock mechanism which selectively prevents the movement of the mode selection lever or the cassette carrying mechanism, and a planetary gear mechanism coupled between the drive motor and the mode selection lever and the cassette carrying mechanism. The planetary gear mechanism includes a sun gear rotated by the drive motor, a ring gear which steadily meshes with one of a first rack provided on the mode selection lever and a second rack provided on the cassette carrying mechanism, and a carrier which steadily meshes with another of the first rack and second rack. The lock mechanism selectively prevents the movement of the mode selection lever or the cassette carrying mechanism so that the driving force of the drive motor applied to the sun gear is released from only one of the ring gear and the carrier. The cassette tape player is capable of driving the cassette carrying mechanism and the mode selection lever reliably and enables the cassette tape player to be compact.</p> |
