摘要:
A tape cassette has a housing and a pressure pad apparatus mounted within the housing for bringing a magnetic tape into direct contact with a magnetic head. The pressure pad apparatus includes a pad, a spring joined to the pad for imparting a pushing force to the magnetic head, and a holding member mounted within the housing for holding the spring at two points spaced from each other. The effective length of the spring is greater than the distance between the two holding points of the holding member.

A tape cassette capable of being readily assembled irrespective of a lid for covering a tape being constituted by three lid member and effectively preventing disengagement of a support shaft of the lid from a bearing hold due to application of shock to the tape cassette. A lid including a front lid member for covering a front surface of a tape, an upper lid member for covering its upper surface and a rear lid member for covering its rear surface is arranged so as to be openable with respect to a casing, to thereby selectively expose the tape, wherein a connection between each two of the lid members is constituted by a diameter enlarged section of a support shaft of one of the lid members provided with a cutout and a shaft bearing hole of the other lid member formed with an opening smaller than the diameter enlarged section and substantially equal to or smaller than the cutout.
摘要:
A magnetic tape cassette capable of effectively preventing separation of a slider from a casing even when it is dropped or any external force is applied thereto, resulting in ensuring its safety and reliability. The magnetic case includes a casing constituted by an upper casing member and a lower casing member and a slider slidably mounted on the lower casing member. Each of side walls of the slider includes a lower portion opposite to an outer surface of a side wall of the lower casing member and an upper portion opposite to an inner surface of the side wall of the upper casing member. The cassette also includes a mechanism for preventing the slider from being disclocated from the casing. The mechanism may be provided by positioning the inner surface of the side wall of the upper casing member inwardly from the outer surface of the side wall of the lower casing member. Alternatively, it may be provided by positioning the inner surface outwardly from the outer surface through a slit defined therebetween and forming the upper portion of the side wall of the slider into a thickness larger than the slit.

A cartridge comprises a case consisting of upper and lower shells joined and containing a medium, a shutter which slides astride over one edge portion of the case to open or close a slot formed in the case to expose the medium partly, and a locking member which keeps the shutter in the closing position immovably. The locking member is normally, except when unlocked, exposed partly in a recess for the access of an unlocking member, so that a push of the exposed portion of the locking member disengages it from a projection formed on the inner side of the outer edge of the shutter. Confining structure is provided for confining the position of the exposed portion of the locking member always to the inside of the line extended from the end face of the shutter is provided between the exposed portion and the interior surface of the case.
摘要:
A cleaning disc cartridge capable of concurrently cleaning both a magnetic head of a magneto-optical disc apparatus and an optical lens thereof without causing any error in reading of a signal. A rotating disc is provided on one surface thereof opposite to a magnetic head of the apparatus with a head cleaning member and on the other surface thereof opposite to an objective lens of the apparatus with lens cleaning members. The rotating disc includes a disc body which is provided with an inventory region defined on an inner peripheral side of a lens cleaning member arrangement region, a reproduction-only region defined on an outer peripheral side of the lens cleaning member arrangement region, and an information recording and reproducing region outside the reproduction-only region.

摘要:
A casing for a magnetic tape cassette capable of effectively and precisely actuating a slider. The casing includes a casing body having an upper casing member and a lower casing member joined together. The slider is slidably mounted on the lower casing member so as to cover at least a part of a bottom and a side of the lower casing member. The upper casing member is provided at a rear portion of both sides thereof with holding members through which the casing is grasped. The holding members are separated or isolated from the slider, to assure smooth sliding movement of the slider. The casing body may be provided on both sides thereof with reliefs which serve to prevent the holding members from interfering with movement of the slider.
摘要:
A disc cartridge capable of ensuring its stable and positive operation without damaging a disc while satisfactorily producing a cleaning effect and maintaining adequate contact between the head of a cartridge operating unit and the disc. Each of a pair elastic members respectively mounted on the upper and lower inner surfaces of a casing forcibly presses a sheet-like liner situated between the elastic member and a disc against the disc through a projection portion having a predetermined length formed as part of the elastic member, resulting in the liner contacting the disc with a force at substantially a constant level for a long period of time.
