    Abstract: A tape cassette having a plug for preventing erasure by mistake which may be inserted to make engagement with a recess provided in a peripheral surface of a cassette. The plug has a pair of insertion legs which extend from the ends of a mistake inhibiting web, and engagement portions for engaging mating engagement portions in the engagement recess. The plug may be inserted into the engagement recess from the web side or from the ends of the insertion legs as selected by the user, and the insertion legs will slide along surfaces of the cassette to fill said engagement recess. Different indications may be provided in window openings contiguous to the engagement recess in the cassette proper, according to whether the plug has been inserted from the web side or from the insertion legs, so that the user may know whether the tape cassette is recording correctly or incorrectly.

    Abstract: 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.

    Abstract: In a tape cassette having a cassette casing constituted by upper and lower, substantially rectangular halves which are secured together in mating relation for enclosing a pair of reel hubs rotatably mounted in side-by-side relation and a magnetic tape wound on the hubs and being guided therebetween in a path extending along one side of the casing; each of the upper and lower casing halves includes an opaque frame having a substantially large window opening therein and a window member of transparent resin closing the window opening of the respective opaque frame and being secured to the latter adjacent the peripheries of the window opening and window member, respectively, and projections formed integrally with the window member of at least one of the casing halves and each extending therefrom in the direction toward the interior of the casing for resisting inward removal of the respective window member from the window opening of the respective frame, and thereby maintaining the strength and rigidity of the cassette casing while permitting the use of window members of increased size for improved viewing of the tape and reel hubs within the casing.

    Abstract: PCT No. PCT/JP84/00400 Sec. 371 Date Apr. 4, 1985 Sec. 102(e) Date Apr. 4, 1985 PCT Filed Aug. 10, 1984 PCT Pub. No. WO85/00919 PCT Pub. Date Feb. 28, 1985.A tape cassette for a recording and reproducing apparatus, for example, a video tape recorder, has: a cassette housing which passes a tape housed therein along an opening in the front surface thereof; a front cover pivotally attached to the cassette housing such as to cover the front side of the passed tape; a rear cover pivotally attached to the front cover such as to cover the rear side of the passed tape; a pin to be guided and provided on the rear cover; and a guide groove provided on the cassette housing such as to guide the pin. When the front cover is pivoted in the cover-opening direction, the pin is guided along the guide groove, whereby the rear cover, together with the front cover, is pivoted in the cover-opening direction while the lower end portion of the rear cover is being pivoted with respect to the front cover so as to separate to the rear of the front cover. In the tape cassette, the front surface of the lower end portion of the rear cover has a slanted surface which is slanted backwardly from its lower end towad its upper end, and further, this slanted surface is set such that, in a state wherein the front and rear covers are closed, the slanted surface is located at a position where an upper corner portion of the slanted surface is substantially flush with the lower back surface of the front cover or a position where the upper corner portion is rearward of the lower back surface of the front cover. By thus setting the slanted surface, when the rear cover is closed, the upper corner portion of the front surface of the rear cover is allowed to move such as to greatly separate to the rear of the magnetic tape, thereby making it possible to prevent the magnetic tape from being caught and damaged by the upper corner portion of the rear cover.

    Abstract: A tape cassette having a lid (5) pivotally supported at two side walls of the cassette housing (1) so as to open or close a tape withdrawing mouth (4) has a lid lock member (9) for locking said lid at a closed position. Upon use, the tape cassette is loaded on a recording and/or reproducing apparatus having an optical tape end sensing device formed of a light emitting element and a light receiving element. The lid lock member includes a light leading cover or tunnel piece (19) which coincides with a light path which extends from the light emitting element to the light receiving element. This tape cassette also has an opening (11) formed through its side walls so as to communicate with the light path, wherein an outer end portion of the tunnel piece is inserted into the opening portion.
