  • Patent number: 5486958
    Abstract: A video cassette tape recorder capable of driving various functional parks by a single loading motor, thereby obtaining a light, thin, simple and compact construction and reducing the manufacture cost. A construction is provided in which a single loading motor drives a rotation head drum mounted on a rear portion of a base plate, an actuating plate mounted on a bottom surface of the base plate to linearly laterally move between a supply reel and a take-up reel both mounted on a front portion of the base plate, a pinch drive assembly disposed on one side of the take-up reel and adapted to drive the pinch roller, and a front loading housing.

  • Patent number: 5472151
    Abstract: A fast winding device for a video cassette tape recorder capable of achieving a fast winding operation at both of tape loading and unloading states by use of a fast winding plate having an extension to which a FF/REW gear is mounted. The device includes an actuating plate mounted on a lower surface of a base plate to move linearly laterally, the actuating plate having a first fast winding actuating groove and a second fast winding actuating groove, a fast winding mode plate disposed between the base plate and the actuating plate to move laterally linearly, a fast return spring for returning the fast winding mode plate to an original position, a FF/REW gear rotatably mounted to an extension of the fast winding mode plate and directly engaged with an idler mechanism, a spring for resiliently supporting a lock lever mounted to the fast winding mode plate, and a ratchet mounted to the fast winding mode plate and adapted to release a locking state of the lock lever.

  • Patent number: 5434726
    Abstract: A tape running device of a video cassette recorder. This device comprises a capstan shaft, an arm pinch having both a tape guider and a rotatable pinch roller, a holder provided under the arm pinch in order to elevate, lower and rotate the arm pinch, a gear pinch engaging with the holder for guiding the elevating and lowering motion of the holder, a guide plate engaging with the holder for causing the holder to be vertically elevated and lowered, a take-up arm rotatably mounted on the main plate and having a shaft for pulling the tape out of a tape cassette, and a connection gear gearing into both the gear pinch and the take-up arm in order to transmit the rotational force of a drive motor to them and rotating the holder in order to rotate the arm pinch toward the capstan shaft. The tape is run under the condition that its nonmagnetic surface is wrapped about both the tape guider and the pinch roller.
