摘要： In a disk cartridge in which a sheet-like recording medium is fixed to the periphery of a circular center plate which has an approximately square center hole and an almost rectangular eccentric driving hole, and a cartridge rotatably accommodating the sheet-like recording medium and including an upper half and a lower half having a turntable insertion hole in which the circular center plate is loosely fitted; the sheet-like recording medium is positioned in the cartridge by restricting the movement of the circular center plate at the central portion thereof, so that the diameter of the circular center plate can be substantially decreased and aberration of tracking or the like during recording or reproducing is avoided as much as possible.

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.
摘要翻译：带盒设置有用作卷轴锁定释放元件的滑块，并且可沿着由导轨限定的路径沿着前后方向在盒的后部附近移动。引导槽形成在盒的下侧，与滑动件的引导件对准。滑块具有通过引导件中的细长开口延伸到引导槽中的向下突出部。向下的突出部被内置于重放单元中的突起抵靠，并且被容纳在引导槽中，用于在插入到重放单元或VTR期间引导盒。因此，盒的插入导致盒引导突起移动用于释放磁带卷轴的滑块。

摘要： A reel on which a web, such as magnetic tape, is to wound is formed of molded synthetic resin and comprises a generally cylindrical hollow reel hub, a circular flange at one end of the hub and integrally formed therewith, and a rib portion generally closing off the other end of the reel hub. A circular sub-flange is thermally welded to the rib portion at that end of the reel hub, for instance, by an ultrasonic welding technique. In order to prevent the reel hub, in which the synthetic resin material may have undergone a dimensional change after welding, from causing undulations in an edge of the tape wound on it, the reel hub is provided with a thin cylindrical portion at the same end of the hub as the rib portion. The top of the cylindrical portion is separated from the sub-flange. The thin cylindrical portion can be defined by an annular recess in the end of the hub. In one arrangement, an annular cut-out is provided contiguous with the annular recess and the cut-out receives a mating projection on the sub-flange.

摘要： A reel includes a pair of segments which are demountable from each other and one of which is moulded integrally with a flange, while the other segment includes a segmental inner member and a segmental outer member which are connected by a pair of connecting members at their ends. The outer member is prevented from deforming polygonally by providing a sectorial space between the inner member and the outer member, with a clearance between the inner member or the outer member and the adjacent rib which extends almost across the sectorial space.

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.
