摘要： In an auto-exchanger disc apparatus, both a disc cartridge for stocking plural discs and a pickup cartridge having a pickup are provided with common recesses, and a cartridge stocking unit is formed with a projection which is engaged with the recesses, whereby the cartridges can be exchanged for each other and mounted on the disc apparatus. Therefore, the extension and maintenance of the cartridges can be facilitated. When a double-side reproducing operation is performed, the pickup cartridge is turned upside down and then mounted on the disc apparatus, whereby the double-side reproduction can be surely performed by the disc inverting means. Further, disc inclining means is provided to prevent a disc being returned from the disc feeder to the disc cartridge from abutting against the disc cartridge. The disc inclining means and the disc inverting means may be integrally constructed by the same member to reduce the cost. Still further, a cleaning member is provided to some or all of the rollers for feeding the disc to perform a disc cleaning operation as well as a disc feeding operation, thereby preventing dust from being attached to the disc.

摘要： A tape running guide and tape loading mechanism for magnetic tape recording and reproducing device allows a cylinder drum carrying magnetic heads to minimize its size by employing a three-dimensional loading system is employed in which a level of tape fed to a cylinder drum is made high and that of the tape leaving the cylinder drum is made low. A tape guide system includes, in the tape supply side, at least a first, movable slanted pin and a first, movable tape height regulation guide roller for deriving the tape from an open space of a magnetic tape cassette and winding the tape on the cylinder drum, a second slanted pin and a second tape height regulation guide roller and a third, movable guide pin for winding the tape on the second slanted pin are provided and, in the tape returning side, a fourth, movable slanted pin and a fourth, movable tape height regulation guide roller for deriving the magnetic tape from the open space of the tape cassette and winding the magnetic tape on the cylinder 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 arranged outside the open space. These movable tape guide members are movable on a common area in time-shared manner to thereby make the loading mechanism compact.

摘要： A slide type cassette loading apparatus includes a loading section (20) for receiving a tape cassette (31) to move the same between an inlet/outlet position and a reference position for loading, and a movable chassis (3) 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 (20) is of a double structure type which has an outer cassette holder (5) pivotable relative to the movable chassis (3) and an inner cassette holder (4) supported to the outer cassette holder (5). The inner cassette holder (4) is mounted on the outer cassette holder (5) so as to make a pivotal movement together with the outer cassette holder (5) and be movable in slide directions of the cassette (31), and is operatively coupled to the movable chassis (3) so as to be movable together with the movable chassis (3).
