    摘要: In a rotary head drum of a recording/reproduction apparatus, for smoothly holding a magnetic tape over a guide step provided on a lower drum to guide the magnetic tape, part of a chamfer formed in the guide step is formed as a large chamfer in which a chamfered amount is larger than that of the remaining part of the chamfer. With the provision of the large chamfer, even if the lower edge of the magnetic tape deviates from the guide step when the tape is wound over or unwound from the drum, damages of the magnetic tape can be prevented. Therefore, the position and attitude control of tape withdrawing members can be greatly simplified and the magnetic tape can always run stably while being restricted in its position by the guide step. In the process of machining a tape running surface on the drum, by increasing the feed distance of a blade in the part of the chamfer where the large chamfer is to be formed by chamfering the guide step with a large chamfered amount, in comparison with the feed distance set in the remaining part of the chamfer, the large chamfer and the small chamfer can be both machined at the same time, resulting in simplified machining steps.

    摘要: A magnetic tape guide mechanism for a magnetic recording/reproducing apparatus which includes a base having a large-inner-diameter hole with a larger inner diameter than a shaft hole, and a resilient synthetic resin member located in the large-inner-diameter hole and surrounding the shaft of a tape guide. As a result, a horizontally extended threaded hole and fixing screw conventionally required are eliminated and the overall construction is simplified. Moreover, the adjustment work is facilitated and the overall production cost of the components are substantially reduced.

    摘要: A magnetic recording and reproducing apparatus including a reel drive system having a first transmitting path for high-speed magnetic tape feed, and a second transmitting path for constant-speed magnetic tape feed. The first transmitting path includes a drive pulley for driving a pair of magnetic tape reels through oscillating idler means which is supported on a support shaft located on a bisector perpendicular to the center of the pair of magnetic tape reels to directly transmit the rotation of a reversible motor to the drive pulley. The second transmitting path transmits the rotation of the reversible motor through a slip mechanism to obtain a predetermined output torque. One of the two transmitting path is selected for each operation mode as switching of the operation modes is effected.

    摘要: In a magnetic recording and reproduction apparatus, for simplifying the structure of a fixing device of an audio-control head and for decreasing the number of adjustment procedures, a synthetic resin part formed of a plate member is molded of a resin integrally with a shaft part extending in a through hole in a base and with a fixed part provided on the opposite surface of the base to the surface of the base on which the plate member is provided, so that the synthetic resin part can be rotated around the through hole; an audio-control head is provided on a head plate, which is pressed toward the base by a spring fitted on a spring fixing screw; and three adjustment screws include screw parts which support the head plate, and cylindrical parts which abut against the surface of the base through holes bored through the synthetic resin part. Positioning of the audio-control head in a moving direction of a magnetic tape is effected by an adjustment jig between a notch on the synthetic resin part and a projection part on the base. Two of the adjustment screws are located on a straight line passing the center of the through hole in the base and the center of a control head, which positions are on the front and rear sides of the control head. Mainly, the height of the audio-control head is adjusted by one of the adjustment screws, the inclination angle .theta. is adjusted by another adjustment screw, and the azimuth angle is adjusted by the other one.

    摘要: A cleaning device for cleaning a rotary magnetic head of a magnetic recording and reproducing device includes a cleaning member which is movable into and out of contact with the rotating magnetic head. The cleaning device is activated through the operation of a manually operable button and under the control of an electronic control device. The cleaning member is automatically brought into contact with the magnetic head to clean the same. The operation of the cleaning device is carried out in association with an operation of a tape loading mechanism of the magnetic recording and reproducing device. The vertical position of the cleaning member is changed when it is contacted with the magnetic head, so that the portion of the cleaning member to be contacted with the magnetic head is changed.

    摘要: A light-emitting element and light-receiving elements are embedded upright in a single printed wiring board for cooperating with one another in detecting the leader tape portion of a magnetic tape. Such a printed wiring board is fixed to a chassis by means of which a magnetic tape cassette is held in position. This arrangement enables a reduction in the number of leads and connectors, and hence greatly decreases the number of connections to the body of a magnetic recording and reproducing apparatus, thereby improving its adaptability with respect to automated assembly.
