摘要： An improved disc cassette having a shutter-closeable aperture, wherein the shutter is moved against the force of a confined coil compression spring into an aperture-open condition and is there latched by a transversely deflectable latch pawl normally biased into latching position and operable by manual pinching of the cassette to release the pawl to permit the spring to return the shutter to the aperture-closed position.

摘要： A tape cassette for use with a cassette adapter in a video tape recorder (VTR) of the type including a reel driving device, includes a housing; a supply reel rotatably positioned within the housing; a take-up reel rotatably positioned about a fixed axis of rotation within the housing and including a lower flange having a periphery; and an engaging device formed by gear teeth on the periphery of the lower flange, or a first gear rotatably positioned about the fixed axis of rotation adjacent the lower flange and having a periphery and gear teeth formed on its periphery; the reel driving device including a rotatable second gear having gear teeth for engaging with the gear teeth of the engaging device through an opening in the housing to rotate the take-up reel, or a cassette adapter positioned within the apparatus for housing the cassette and having a drive gear with gear teeth for engaging with the gear teeth of the engaging device through the opening in the housing and a drive shaft for engaging with the drive gear to control the latter to rotate the take-up reel. The cassette also includes a lid pivotally mounted to the front of the housing and a lid lock device for preventing pivotal movement of the lid to its open position when the cassette is not positioned within the VTR.

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 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.
