Abstract: A reel brake device in a recording and reproducing apparatus is operated by a tape loading mechanism. A cam portion is formed on any one side of at least one of a pair of loading gears employed for driving a pair of tape guide units which draw a tape from the cassette. The reel brake for braking the reels includes a friction member for braking the supply reel table and an operating portion which comes into contact with a cam surface and a cam protrusion surface of the cam portion selectively so that it may be driven. Under a tape unloading condition, the reel brake performs braking or releasing operation of the reels as the loading gear rotates in a predetermined direction. Driving of the reel brake by the existing loading gear without using any separate driving element, makes it possible to maintain the brake stroke, enhance the accuracy in operation, and reduce the number of elements constituting the supply reel brake device.

Abstract: An improved cable connecting apparatus between an audio control head and a main printed circuit board for a VCR capable of making it easy to connect between a loading motor and audio control head and a main printed circuit board, so that a more correct connection therebetween is obtained, according to an aspect of the present invention, which includes a main printed circuit board; a base plate; a printed circuit board attached to a loading motor mounted on the deck for driving a tape; an audio/control head mounted on the base plate for detecting/recording a predetermined signal; a signal transmitting member for connecting between the audio/control head and the printed circuit board; and a signal connecting member mounted in the printed circuit board for transmitting signals of the audio/control head and the loading motor to the main printed circuit board.

Abstract: A fast running mode conversion device for magnetic recording and reproducing apparatus. This device has a shaft supporter provided on the bottom surface of a base plate. An idler lifting lever for lifting or lowering an idler arm is pivotally mounted on the shaft supporter. A drive arm for driving the idler lifting lever is rotatably mounted on a shaft of the base plate. A biasing member coupled to the drive arm has a biasing lever for driving the idler lifting lever. The biasing lever extends toward the idler lifting lever. A function plate rectilinearly reciprocates by the rotating force of a cam gear, thus to turn the drive arm. The drive arm has an operating pin and the function plate has a pair of cam projections for cooperating with the operating pin when turning the drive arm.

Abstract: A jog device for magnetic recording and reproducing apparatus. The jog device temporarily rotates a clutch gear of the tape supply reel clutch during a mode conversion from a normal-direction reproducing mode into a reverse-direction reproducing mode. The jog device includes a clutch gear rotating unit, a rotating unit drive member, and a returning unit. The rotating unit includes a jog lever and a gear lever cooperating with the jog lever and selectively rotating the clutch gear. The drive member is a cam gear having a pinion gear gearing into and cooperating with a rack gear of a mode conversion function plate. The cam gear has a cam slot cooperating with a cam pin of the rotating unit. The returning unit includes a coiled torsion spring fitted over a shaft of the rotating unit and a pair of spring arm stoppers.

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.

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.
