  • Patent number: 5315460
    Abstract: A tape running guide and tape loading mechanism for a magnetic tape recording and reproducing apparatus including a tape guiding system having, at a tape supply side, at least a first movable slanted pin and a first movable tape height regulating guide roller for deriving a tape from an open space of a magnetic tape cassette and winding the tape on a cylindrical drum, a second slanted pin and a second tape height regulating guide roller and third movable guide pin for winding the tape on the second slanted pin. At a tape returning side, a fourth movable slanted pin and a fourth movable tape height regulating guide roller for deriving the magnetic tape from the open space of the tape cassette and winding the magnetic tape on the cylindrical drum a fifth movable slanted pin and a pinch roller which are to be derived from the open space of the tape cassette and a capstan in arranged outside the open space.

  • Patent number: 5278707
    Abstract: A plurality of tape guides are moved to wind a magnetic tape on a rotatable cylinder when the magnetic tape is to be loaded. An auxiliary guide mounted on a chassis of a magnetic recording and/or reproducing apparatus in position is made to touch the magnetic tape during a period for which the magnetic tape is being loaded, but it does not touch the magnetic tape when the magnetic tape has been loaded. The auxiliary guide can be protruded toward the magnetic tape from between the tape guides moving to touch the magnetic tape during the period for which the magnetic tape is being loaded so that the magnetic tape can be kept to a predetermined span.

  • Patent number: 5124854
    Abstract: A slide type cassette loading apparatus includes a loading section for receiving a tape cassette to move the same between an inlet/outlet position and a reference position for loading, and a movable chassis for sliding the cassette, located in the reference position, to a recording/reproducing position while carrying the cassette on the movable chassis. The loading section is of a double structure type which has an outer cassette holder pivotable relative to the movable chassis and an inner cassette holder supported to the outer cassette holder. The inner cassette holder is mounted on the outer cassette holder so as to make a pivotal movement together with the outer cassette holder and be movable in slide directions of the cassette, and is operatively coupled to the movable chassis so as to be movable together with the movable chassis.

  • Patent number: 5065264
    Abstract: A magnetic recording/reproducing apparatus has a chassis, a rotary cylinder mounted on the chassis, and at least one guide base movably disposed around the rotary cylinder. The guide base is provided with a guide member for drawing out a magnetic tape from a tape cassette. The guide member draws out the magnetic tape from the tape cassette, as the guide base is being moved, and winds the magnetic tape around the rotary cylinder so that a predetermined tape passage is defined. The magnetic recording/reproducing apparatus further has a capstan mechanism for driving the magnetic tape to run the same. The capstan mechanism is arranged on the same side of the chassis on which the rotary cylinder is disposed, and has a capstan downwards extending toward the chassis to come into direct contact with the magnetic tape.
