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.
