Collation and welding of card component sheets can be performed in a simple facility. Plastic cards such as IC cards having substantially no distortion and twisting are provided. A round hole () and an ellipse hole () are formed at the corresponding positions in layered component sheets (to), and positioning pins () are inserted and passed through respective holes. Since at this occasion, the ellipse hole () has play relative to the positioning pin (), the distortion and twisting of each card component sheet can be adsorbed, and the appearance can be improved by avoiding printing dislocation and the like. It is also able to prevent mechanical strength from lowering due to residual stress.

Correction of card sheets in an aligned positional relationship

An attachment apparatus and method for attaching a disc protective sheet to at least one half of a magnetic disc cartridge body include a supporting mechanism that supports each half body section of the cartridge body. The apparatus and method also include a supply mechanism that provides disc protective sheets to the one half body section. Each protective sheet is punched from a web of material and includes a cutout that corresponds to an opening provided in the one half body section to expose part of a magnetic disc held within the body when assembled. Each protective sheet also includes a thermal fusible layer on an attachment surface opposite a surface that will face a disc when the cartridge body is assembled. Each protective sheet to be assembled is arranged so that the cutout and the opening in the one half body section corresponds to one another. A fusing mechanism has a shape that is slightly larger than that of the protective sheets and is positioned directly over the supporting mechanism. A one half body section including a sheet to be fused is positioned therebetween. The fusing mechanism presses the protective sheet and fuses the fusible layer to the one half body section to fixedly fuse the sheet to the body section. The supporting mechanism and fusing mechanism are moved toward one another to sandwich the one half body section and the protective sheet to be fused therebetween.

Attachment method for disc protective sheet

An attachment apparatus for disc protective sheet which is adapted for attaching disc protective sheet for protecting disc rotatably accommodated within a cartridge body formed by connecting or joining a pair of upper and lower halves with respect to the surface opposite to the disc of the half. This apparatus comprises a supporting mechanism for supporting halves constituting the cartridge body to which disc protective sheets are attached, a supply mechanism for supplying disc protective sheet to the half, the disc protective sheet being such that a cut portion larger than an opening portion provided at the half and facing a portion of the disc toward the external is provided and a thermal fusible layer is provided on the attachment surface of the surface opposite to the disc of the half in the state where the thermal fusible layer is opposed to the surface opposite to the disc of the half and the cut portion is caused to correspond to the opening portion, and a fusing mechanism having outer shape slightly larger than that of the disc protective sheet and disposed in a manner opposite to the supporting mechanism, the fusing mechanism serving to fuse the thermal fusible layer of the disc protective sheet delivered to the half to fixedly fuse the disc protective sheet onto the half. When the supporting mechanism is moved toward the fusing mechanism side so that the fusing mechanism and the supporting mechanism are relatively moved, the disc protective sheet is fixedly fused onto the surface opposite to the disc of the half by the fusing mechanism.

A polishing apparatus includes a lapping tape for polishing a surface of a magnetic disc, a tape supply unit for supplying the lapping tape, a varnisher roller for pressing the lapping tape onto the surface of the magnetic disc, and a pressing unit for pressing the lapping tape to the surface of the magnetic disc by way of the varnisher roller. The pressing unit is constituted by a swing lever having the varnisher roller at one end portion, and a balance adjusting unit. The balance adjusting unit sets the pressing force to zero by establishing the balance of the swing lever, and then breaks the balance so as to press the lapping tape to the surface of the magnetic disc by way of the varnisher roller with a desired pressing force.

A disc cartridge assembling apparatus in which a protuberance formed on the inner surface of one of cartridge halves of a thermoplastic resin making up a main cartridge body unit is passed through a through-hole formed in the other cartridge half in register with the protuberance, and in which the distal end of the protuberance is thermally deformed to interconnect the cartridge halves. The upper and lower cartridge halves are stacked together, with a protuberance formed on the upper cartridge half being passed through the through-hole formed in the upper cartridge half, and are held by a holding mechanism. In this state, the distal end of the protuberance is thermally deformed by a caulking head, heated by a heater, and which is provided with a recess in its surface adapted to compress against the protuberance. Then, as the caulking head is moved away from the thermally deformed protuberance, the caulking head and the protuberance are cooled by a cooling mechanism. This effectively shortens the caulking process since the thermal deformation of the protuberance until the solidification.

A method of printing on a container casing for containing recording media, such as tape-shaped or disc-shaped recording media, includes the step of forming an underlying layer by printing on the outer surface of the main casing member, forming a colored layer on the underlying layer by color printing based on the picture information, and forming a protective layer on the colored layer for protecting the colored layer. The protective layer has an opening for exposing its partial portion to the outside.

A cassette includes a cassette main member. The cassette main member has recessed and convexed surface regions on which color printing is formed. The color printing is formed by ejecting ink vertically downward from a series of three ink jet printing heads to form two printed layers and a third, protective layer. The first printed layer is a solid white base coating on which the second layer is printed. This second layer is full-color and is based on picture information. The third layer is formed over the full-color second layer and serves as a protective coating.

A container casing for containing recording media, such as tape-shaped or disc-shaped recording media, has an underlying layer, a colored layer and a protective layer. The underlying layer is formed by printing on the outer surface of the main casing member. The colored layer is formed on the underlying layer by color printing based on the picture information. The protective layer is formed on the colored layer for protecting the colored layer. The protective layer has an opening for exposing its partial portion to outside.
