摘要： In a flexible magnetic disc apparatus having a disc drive unit including a spindle with a cylindrical peripheral surface terminating at an upper margin thereof and a seating surface provided on the disc drive unit in a plane normal to the central rotary axis of the cylindrical peripheral surface, and a record disc including a flexible magnetic disc member, a reinforcing core member secured to the disc member at the center thereof and having an aperture for receiving the spindle and a reference surface engageable with the seating surface to limit the extension of the spindle through the aperture, spindle positioning projections extending into the aperture for engagement with the spindle therein and a resilient member extending into the aperture for pressing the spindle therein against the positioning projections; the top edges of the spindle positioning projections are located in respect to the reference surface so that, when the record disc is mounted on the disc drive unit with the reference surface engaging the seating surface, the cylindrical peripheral surface of the spindle always extends above the top edges of the positioning projections, not withstanding the standard dimensional tolerances, for ensuring that the positioning projections will accurately center the flexible magnetic disc member relative to the rotary axis.

摘要： A tape cassette is provided with a slider serving as a reel lock releasing element and which is movable in the front-to-rear direction near the rear of the cassette, along a path defined by a guide. A guide groove is formed in the underside of the cassette in alignment with the guide for the slider. The slider has a downward projection extending into the guide groove through an elongated opening in the guide. The downward projection is abutted by a projection built into the playback unit, and which is received in the guide groove for guiding the cassette during its insertion into the playback unit or VTR. Therefore, insertion of the cassette causes the cassette guiding projection to displace the slider for releasing the tape reels.

摘要： A flexible disc cassette is provided with a shutter which is capable of opening/closing a head access hole and a pad insertion hole respectively formed in upper and lower halves thereof. A V-shaped torsion spring is used as the spring for biasing the shutter in the closed position. The lengths of the linear arm portions integrally formed with both sides of the coiled portion of the spring are approximately the same. Both tips of the arm portions are bent at approximately 90.degree. so as to form the L-shaped hooks which has the same length and which extend in the opposite directions along the height of the coiled portion. The L-shaped hooks are stopped by the shutter and the cassette case.

摘要： A magnetic tape cassette is provided with a reel brake and a tape-protecting lid. The tape-protecting lid has side plates extending parallel to the side walls of the cassette casing and pivoted on the side walls. The reel brake mechanism comprises a brake plate free to move between a braking position and a brake-release position and normally biased toward the braking position. One of the reel brake plate and the side wall of the casing is provided with means for maintaining interengagement between the reel brake plate and the side wall so as to ensure cooperation therebetween for automatic brake release in response to opening of the tape-protecting lid.

摘要： A magnetic tape cassette includes a casing with a substantially straight side along which a peripheral wall has an opening for access to magnetic tape contained in the casing between its top and bottom walls which have edge portions projecting beyond the peripheral wall along the straight side, and a lid member having an elongated plate portion dimensioned to extend along the straight side of the casing and to fit closely between the projecting edge portions and ears projecting from opposite ends of the plate portion for disposition against respective end portions of the peripheral wall. Pivot pins are loosely received in respective, preferably triangular, apertures for connecting the ears of the lid member with the casing to permit pivoting of the lid member and its bodily displacement relative to the casing in directions at right angles to the pivoting axis. Thus, the lid member is movable, by a combination of the pivoting and bodily displacement thereof, between a closed position in which the plate portion is between the projecting edge portions at the straight side of the casing for closing the opening therein and an opened position in which the plate portion of the lid is disposed at the outside of the top or bottom wall of the casing adjacent the respective edge portion. Coil springs are connected between the casing and lid member of pivotally urging the latter to a neutral pivoted position in which the plate portion is centered between the projecting edge portions and bodily urging the lid member, in its neutral pivoted position, toward the straight side of the peripheral wall of the casing.
