Abstract: 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.

Abstract: A reel flange for a tape reel in a tape recording system which has an annularly-shaped projecting portion which merges into a recessed annularly-shaped control portion. A plurality of inwardly-directed rib members extend inwardly from the projecting portion into the recessed central portion to aid in the alignment of the reel flanges when stacked during manufacture. Openings in the recessed control portion receive mating pins located on a cylindrical projecting portion intermediate the flanges of the reel to secure the flange to the projection portion. The flange further defines a stacking-pin receiving opening with an alignment lug. The thickness of the projecting portion of the reel flange may also decrease with increasing radial distance from its center.

Abstract: In a video tape cassette having upper and define a substantially rectangular housing with an opening extending along a side thereof between end walls of the housing for containing reels having tape wound thereon and guided between the reels in a run extending across the opening, and a lid structure which is pivotally mounted on the housing for movement by a coil spring from an open position exposing the tape run to a closed position in which the lid structure covers the tape run; the assembling of the tape cassette is facilitated by providing anchors on the lid structure by which the coil spring is initially or tentatively located during the mounting of the lid structure on one the housing portions, whereupon the coil spring is transferred into engagement with an anchor on that one housing portion in preparation for assembling of the latter with the other housing portion.

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.

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: 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 cas

Abstract: In a tape cassette with a housing including top and bottom walls having respective pairs of spaced apart openings aligned with each other, a pair of hubs disposed rotatably within the housing between the walls and being accessible through the respective aligned openings for selectively driving the hubs of the cassette, and a magnetic tape wound on a cylindrical circumferential surface of an outer peripheral portion of each of the hubs; each of the hubs includes an annular rib radially inward from the outer peripheral portion and projecting axially beyond opposite flanks of the outer peripheral portion of the hub so as to extend rotatably around annular flanges directed axially inward from the respective aligned openings of the housing walls, and a pair of lubricating sheets are disposed against the inner surfaces of the housing walls and each have a pair of ridges or beads projecting therefrom and a pair of holes located between the ridges and through which the annular flanges on the adjacent wall extend with
