A vibration damping support mechanism for a recored data reproducing apparatus is provided which allows the apparatus to be installed in either a horizontal or vertical position without shifting the tensioning direction of damper springs. Each pair of the damping springs is mounted between a main reproducing unit and an outer casing. The two damper springs are arranged to extend in the thicknesswise and depthwise directions of the main reproducing unit respectively or arranged tilting at a predetermined angle. In the horizontal position, external vibrations are absorbed by the elastic action of one of the two damper springs and thus prevented from propagating directly to the main reproducing unit. Similarly in the vertical position, such external vibrations are absorbed by the elastic action of the other damper spring and prevented from propagating directly to the same. In another construction, a damper spring is mounted between a side panel of the main reproducing unit and a projection of each spring loaded arm rotatably mounted to the outer casing. The spring loaded arm rotates 90 degrees when is actuated by a shift lever pressed with each shift pin of a vertical mounting bracket, thus resetting its damper spring for corresponding to the horizontal or vertical position of the main reproducing unit.

A CD player has an inner casing, a plurality of magazines provided in the casing, each of the magazines storing a plurality of CDs, a lifting device, and a movable member or casing. The movable casing has a reproducing device, a loading device for loading one of the CDs on the reproducing device, and is adapted to be lifted by the lifting device. A lock plate is slidably provided on a wall of the movable casing. A lock device is provided to drive the lock plate to engage locking teeth on the inner casing for locking the lock plate to the wall of the inner casing to prevent vertical movements of the movable member while in a playing position.

The spring loaded arm rotates 90 degrees when is actuated by a shift lever pressed with each shift pin of a vertical mounting bracket, thus resetting its damper spring for corresponding to the horizontal or vertical position of the main reproducing unit. In a further construction, a connecting rod arranged extending at one end outward from the outer casing is used to rotate the spring loaded arm through 90 degrees upon coming into direct contact with e.g. the floor of a vehicle.

A threading device for a tape recorder installed in vehicle includes a pair of slide blocks which are provided with guide rollers for drawing a tape from a tape cassette and winding the tape on a cylinder head. One of the slide blocks is abutted against a guide groove, and a tension arm is abutted against the other slide block to thereby prevent the rattling of the slide blocks due to vibration produced during operation of the vehicle.

A tape cassette push-out device for a tape recorder includes a push-out mechanism for pushing the rear face of a tape cassette (A) thereby moving the cassette to a cassette insertion opening (2) of the recorder. Before the push-out mechanism is operated, a cassette box (7) for holding the cassette is first moved from a tape driving position to a position adjacent to the backside of the cassette insertion opening. After operation of the push-out mechanism, the mechanism is retractable away from the cassette.

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.

In a head rotation mechanism in an auto-reverse type tape player, the head rotation mechanism comprising a sector gear engaging with a cam gear provided on a head lead side of a rotary head; a boss extending in the direction opposite to the rotary head side of the sector gear and having a tapered foreend; and a link mechanism for rotating the head. The link mechanism is rocked by the cam gear and equipped with a U-shaped member engaging with the boss on the sector gear. The boss on the sector gear engages with the U-shaped member of the link mechanism for rotating the head only when the rotary head is located at a release position, and the boss is out of contact with the U-shaped member when the rotary head is located ahead of the release position, whereby a reversible rotation of the single cam gear is used to change a direction of the rotary head and move the head forward.
