Abstract
A disk cartridge holding therein a disk which is centrally attached with a disk-shaped center hub via a tacky ring formed of ring-shaped double sided adhesive tape material is produced by: driving a base film with tacky rings being attached on an upper surface of the base film; feeding the base film such that at least one of the tacky rings is positioned at a hub-attaching position; at the hub-attaching position, temporarily attaching each center hub onto the base film via each tacky ring; and guiding the base film in a direction in which the base film is folded back about an apex of a wedge portion of a guide member provided with the wedge portion, such that the base film is caused to be peeled off from the tacky ring.
Claims8
An method of attaching a disk-shaped center hub of a disk cartridge to a rotary disk as an information recording medium, wherein the disk cartridge comprises the rotary disk;
- and a flat housing in which the rotary disk is rotatably held, and wherein the disk-shaped center hub is centrally attached to the rotary disk via a tacky ring formed of ring-shaped double sided adhesive tape material;
- the method comprising the steps of:
- (1) providing and arranging a plurality of the tacky rings on a strip-like carrying base film;
- (2) feeding the base film such that at least one of the tacky rings is positioned at a first hub-attaching position;
- (3) at the first hub-attaching position, temporarily attaching each center hub onto the base film via each tacky ring;
- (4) guiding the base film in a direction in which the base film is folded back such that the base film is caused to be peeled off from the tacky ring which has been attached to both an upper surface of the base film and a lower surface of the center hub;
- and
- (5) thereafter, at a second hub-attaching position, attaching the center hub onto the disk via the tacky ring which has been attached to the lower surface of the center hub.
An apparatus for attaching a disk-shaped center hub of a disk cartridge to a rotary disk as an information recording medium, wherein the disk cartridge comprises the rotary disk;
- and a flat housing in which the rotary disk is rotatably held, and wherein the disk-shaped center hub is centrally attached to the rotary disk via a tacky ring formed of ring-shaped double sided adhesive tape material;
- the apparatus comprising:
- base film driving means for driving and feeding a carrying base film with a plurality of the tacky rings being arranged on an upper surface of the base film, such that at least one of the tacky rings is positioned at a first hub-attaching position;
- first hub-attaching means for attaching at the first hub-attaching position the center hub to the base film via the tacky ring;
- guide means for guiding the base film in a direction in which the base film is folded back about an apex T of a wedge portion provided in the guide means, such that the base film is caused to be peeled off from the tacky ring which has been attached to both an upper surface of the base film and a lower surface of the center hub;
- and
- second hub-attaching means for attaching at a second hub-attaching position the center hub to the disk via the tacky ring which has been attached to the lower surface of the center hub.
