A cassette tape deck for use with a tape cassette having a magnetic tape wound on reels in a casing, which is designed to record signals on the tape or reproduce them therefrom based upon loading of the cassette, and in which at least one guide pin having slidably mounted thereon a sliding member biased toward the upper end of the guide pin and the sliding member has formed therein a groove or aperture extending perpendicular to the sliding direction thereof and has associated therewith a movable member biased toward the guide pin, whereby when the cassette has been loaded on the tape deck at a predetermined position, the groove or aperture of the sliding member receives the movable member to detect the loading of the cassette at the predetermined position and actuation of tape driving means is allowed based upon the detection of the loading of the cassette; in which left and right braking members attached to a lever associated with left and right actuating levers for urging left and right pinch rollers into rotary contact with left and right capstans with the tape being gripped therebetween respectively and for pressing the magnetic head against the tape is selectively brought into contact with left and right wheels mounted on left and right reel shafts, whereby the tape is driven across the magnetic head while being subjected to required back tension; and in which the tape is driven to the right (or left) under such conditions that left and right pinch rollers are held in rotary contact with left and right capstans with the tape being gripped therebetween respectively and the contact pressure of the left (or right) pinch roller to the left (or right) capstan is held lower than that of the right (or left) pinch roller to the right (or left) capstan, whereby the tape is driven across the magnetic head while being subjected to required back tension.

A mode setting device for establishing various driving modes in a magnetic tape driving apparatus, comprises a cam member, and a cam guide member guided by the cam member to be shifted between a plurality of positions. And a brake member and a pinch roller are located in positions corresponding to a plurality of magnetic tape driving modes as the cam guide member is shifted between the plurality of positions.
A new cassette tape player is provided. It comprises a cassette holder, an actuator arm pivotally disposed within the chassis, a slide plate which moves with the rotation of the actuator arm, a hook plate to lock the slide plate at a locking position, and a cassette positioning lever to rotate upon completion of actuator arm to ensure that the cassette received in the cassette holder is properly positioned. The hook plate is also provided with means for damping a shock inflicted thereon.
A dual capstan tape transport mechanism having a magnetic tape trained along a path for movement successively between an upstream capstan and pressure roller, past record and play heads, and between a downstream capstan and pressure roller. A motor drives the downstream capstan directly and drives the upstream capstan indirectly, and slightly slower, through an overrunning clutch. Separate solenoids move the pressure rollers to press the tape against the respective capstans. The mechanism is selectible to play either an improved dual capstan type cartridge with both capstans, or to play a conventional single capstan type cartridge with the downstream capstan alone. Tape guide posts, aligning the tape and providing wrap around the heads, and a shield engageable with the backside of the tape opposite the play head, are movable with the upstream pressure roller through openings in the housing of the dual capstan cartridge.
A brake device for a VCR rapidly stopping the rotation of the supply reel and the take-up reel and reducing the number of brake shafts and brake springs. The brake device includes a supply reel soft brake and a supply reel main brake which are rotatably mounted on a common shaft at a side of the supply reel for braking the supply reel. A take-up reel soft brake and a take-up reel main brake are rotatably mounted on a common shaft at a side of the take-up reel for braking the take-up reel. The brake device further includes a pair of brake springs. One of the brake springs is mounted on the common shaft at the side of the supply reel and biases the supply reel brakes in opposed directions in order to make these supply reel brakes come into close contact with the supply reel. The other spring is mounted on the common shaft at the side of the take-up reel and biases the take-up reel brakes in opposed directions in order to make the take-up reel brakes come into close contact with the take-up reel.
A tape guide device which is used in a magnetic tape driving apparatus employing a tape cassette, comprises a tape guide to touch two longitudinal edges of a magnetic tape in the tape cassette, thereby preventing transverse movement of the magnetic tape, when a fast-forward or fast rewinding mode is established in the magnetic tape driving apparatus.
