摘要： In an optical disc fabricating apparatus, when the disc substrate is lowered from the tip of a disc inserting portion at a center pin down to a disc supporting portion, a disc urging portion of an alignment lever is pressed by a disc substrate, to be thus pushed in toward an inner periphery and a sheet urging portion is pushed out toward an outer periphery, so as to press the inner peripheral surface of a cover sheet so that both of the cover sheet and the disc substrate are urged in an alignment direction. Thus, it is possible to eliminate play generated between the inner peripheral surface of the cover sheet and the outer peripheral surface of a sheet inserting portion and play generated between the inner peripheral surface of the disc substrate and the outer peripheral surface of the disc inserting portion.

摘要： In a process for producing a magnetic disk cartridge by welding two cassette shell halves for constituting a cassette shell of a magnetic disk cartridge to each other, a first fitting part is formed on an inner side of one of the two cassette shell halves. The first fitting part serves to adjust the position of the one cassette shell half with respect to the position of the other cassette shell half. A second fitting part is formed on an inner side of the other cassette shell half, which second fitting part is to be fitted to the first fitting part in order to adjust the position of the other cassette shell half with respect to the position of the one cassette shell half. Projections for ultrasonic welding are formed on a fitting surface of at least either one of the first and fitting parts. While the first and second fitting parts are being fitted to each other, energy of ultrasonic welding is concentrated upon the projections for ultrasonic welding, and the two cassette shell halves are thereby welded to each other.

摘要： A magnetic disc cartridge includes a casing formed by upper and lower shells bonded together. A magnetic disc is supported for rotation in the casing and includes a recording area and a non-recording area around the recording area. A pair of liners are fixed respectively to the inner surfaces of the upper and lower shells to be opposed to the upper and lower surfaces of the disc. Each of the upper and lower shells is provided with at least one protrusion projecting toward the disk from a portion of the inner surface which is outside the portion of the shell opposed to the recording area of the magnetic disc and is opposed to at least a part of the non-recording area of the magnetic disc, whereby the liners on the respective shells are shifted toward the disk from the inner surfaces of the shells by the protrusions.

摘要： A magnetic disk cartridge has a cassette shell made of first and second cassette shell halves formed with pairs of holes for insertion of rivets. The rivets include a flange, elastically deformable bulged portions having tapered surfaces at their distal ends and sloped provisional retaining surfaces at their proximal ends. The cassette shell halves are provisionally assembled by inserting the rivets into the insertion holes from the side of the first cassette shell half to bring the sloped provisional retaining surfaces into engagement with sloped engagement surfaces in the rivet insertion holes of the second cassette shell half. The provisionally assembled cassette shell halves can be easily disassembled if necessary.

摘要： One of cassette shell halves has a cylindrical body protruding toward the other cassette shell half. The cylindrical body has a rivet press-fit hole and is constituted of elastic engagement pieces. The other cassette shell half has an opening for rivet insertion formed in an outer surface, and an engagement piece receiving hole, which communicates from the opening for rivet insertion to the inner surface of the other cassette shell half and has a tapered inner wall surface having the diameter increasing from an end, that stands facing the one cassette shell half, toward the opening for rivet insertion. When the elastic engagement pieces have been inserted into the engagement piece receiving hole, the elastic engagement pieces are brought into pressure contact with the tapered surface of the engagement piece receiving hole by a rivet, which is press-fitted through the opening for rivet insertion and into the rivet press-fit hole, and the cassette shell halves are thus temporarily assembled to each other.

摘要： When assembling a magnetic disk cartridge, a liner material strip having a plurality of circular openings arranged in a row at predetermined intervals is fed intermittently in the direction of the row of the openings and cut to predetermined lengths in synchronization with the intermittent feed to predetermined lengths, whereby liners each having a circular opening is formed. A locator pin which is smaller in diameter than the opening and has an arcuate locating side wall portion the radius of curvature of which is substantially equal to that of the opening is inserted into the frontmost one of the openings with the locating side wall portion opposed to the front edge of the frontmost one of the openings when the liner material strip is stopped. Then the liner material strip is pulled in the direction opposite to the direction of the intermittent feed of the liner material strip so that the front edge of the opening is brought into contact with the locating side wall portion of the locator pin, and the leading end portion of the liner material strip is cut to the predetermined length with the front edge of the opening kept in contact with the locating side wall portion of the locator pin, thereby forming each of the liners.

摘要： In disk cartridge production, in order to enhance adhesion between a disk-shaped center hub provided with a center hole and a tacky ring formed of ring-shaped double sided adhesive tape material, when the tacky ring adhered on a base film is attached to a lower surface of the center hub before attaching the center hub to a central portion of a disk via the tacky ring, the base film is supported from the rear side by an elastic ring pad. The elastic ring pad has an outer diameter which is smaller than the outer diameter of the center hub but larger than the outer diameter of the tacky ring and an inner diameter which is larger than the inner diameter of the center hole of the center hub but smaller than the inner diameter of the tacky ring.
