摘要： Elastic cushion sheets are interposed between the side faces of the tape convolutions and respective halves of the casing of a magnetic tape magazine. The cushion sheets are held on the inner face of the halves by the engagement between a pair of holes provided through each of the cushion sheets and a pair of projections formed integrally on each of the halves. The outer diameter of the projections is slightly smaller than the inner diameter of the holes. The projections are initially formed to extend vertically from each half of the casing, and at least one of them on each half of the casing is made to incline with respect to the vertical after the cushion sheet is put thereon with the holes thereof engaged with the projections. The free end of each inclined projection is moved laterally beyond the edge of the associated hole. The cushion sheet is prevented from falling from the half of the casing even if the half is inverted with the inner face thereof directed downwardly as in assembling the tape magazine, whereby assembly is facilitated.

摘要： Elastic cushion sheets are interposed between friction sheets and the inner walls of the casing of a tape magazine to press the side faces of the tape convolutions. By the pressure of the elastic cushion sheets exerted on the side faces of the tape convolutions, the edges of the tape are effectively aligned in the convolutions.

摘要： Guide bars are positioned to define the center of a magnetic recording medium by contacting the inner circumference of a circular hole of the magnetic recording medium. Through holes are positioned in a medium grasping portion of a lower hub at equal distances from the center of the lower hub. The guide bars are inserted into the through holes of the lower hub and engaged with the inner circumference of the circular hole of the magnetic recording medium mounted on the lower hub. The end portions of the guide bars are then pushed by an upper hub to which a double-faced adhesive member is secured, thereby moving said guide bars away from the surface of the magnetic recording medium and securing the double-faced adhesive member to the magnetic recording medium and the lower hub.

摘要： In a magnetic disk cartridge, a guide member is positioned on a lower half of the cartridge. The guide member has a guide surface standing face to face with a part of a guide groove extending in the surface of the lower half. The guide surface restrains upward movement of a link member coupled with shutter members for magnetic head insertion apertures of the cartridge after the lower side edge portion of the link member is fitted to the guide groove of the lower half when the cartridge is assembled. To prevent the aperture opening movement of the link member, a lock member or a stop wall portion is positioned at a side wall portion of the cartridge.

摘要： A cassette tape having a reduced amount of movement of the tape in the widthwise direction of the tape. A U-shaped shield plate is disposed between and behind guide poles which protrude on both sides of a magnetic head inserting hole. The shield plate has two end portions shaped so as to form a pair of substantially semicylindrically curved pieces extending in the widthwise direction of the shield plate. Each pair is fitted around a corresponding one of the guide poles. A cutout is formed between the curved pieces having a width slightly greater than the width of the magnetic tape, thereby forming a tape running path with the curved pieces.

摘要： A magnetic tape cassette is provided with a pair of rotatable reels each having an upper and lower flange formed with suitable gear teeth. A braking assembly is comprised of first and second ratchet pawls pivotally mounted on a support member which is slidably mounted on the housing of the cassette. The first ratchet pawls are spring biased into engagement with one of the flanges of each reel and are adapted to be pivoted upon insertion of a brake release lever into the cassette. The second ratchet pawl engages the other flange of each reel when the support member is in a first position and is disengaged therefrom when the support member is in a second position.
