Next, a method for manufacturing a pull tab for a recording apparatus according to the present embodiment will be described with reference to FIG.
In this method for manufacturing a pull tab for a recording apparatus, the first laminated sheet 124 is attached to an unwinder, and the one side release sheet is peeled off by the release roller 151 and the take-up winder 154 along the cuts of the release sheet 112. FIG. 17B, which is a cross-sectional view taken along the line XVIb-XVIb, is a cross-sectional view of the first laminated sheet 124 after peeling one side of the release sheet.

  On the other hand, the second laminated sheet 145 applied to the unwinder passes through the guide roller 153 and then passes through the pressure roller 158. At this time, the first laminated sheet 124 and the second laminated sheet 145 are sandwiched by the pressure contact force of the pressure roller 158, and the adhesive sheet 113 exposed about half on the first laminated sheet 124 is separated from the second laminated sheet 145. Glue. The first laminated sheet 124 and the second laminated sheet 145 are laminated as shown in the XVId-XVId arrow sectional view of FIG. From above, the base sheet 141, the adhesive sheet 143 and the release sheet 142 in the second laminated sheet, the release sheet 112, the adhesive sheet 113 and the base sheet 111 in the first laminated sheet.

Next, perforations and punching are performed on the center portion of the fed sheet. The perforation processing unit 160 is a step for perforating the fed sheet, and the punching unit 161 is a punching step for punching.
FIG. 18 is a conceptual diagram for explaining such a process. FIG. 18A is a conceptual plan view showing a portion to be perforated, and FIG. 18B is a sectional view thereof. FIG. 18C is a conceptual plan view showing a portion to be punched, and FIG. 18D is a sectional view thereof.
First, the perforation processing unit 160 will be described.
The perforation is perforated so as to correspond to one bent portion of the base sheet 141. As shown in FIG. 18A, the second laminated sheet has a dotted line 167 indicating the edge of the release sheet and a dotted line 168 indicating one bent portion. A dotted line indicating one bent portion corresponds to a portion that is branched off from the first laminated sheet when the recording device pull tab is attached to the storage medium.

An arbitrary perforation 164 is drilled at an arbitrary location on the dotted line 168 and punched in the next step. As shown in FIG. 18B, the perforation is perforated by a press 171 that moves up and down.
When the perforation is formed, it becomes easy to bend along the side surface of the storage medium when the recording device pull tab is affixed to the storage medium, so that excessive slack can be prevented.
Next, the punching part 161 will be described.
In the punching process, punching is performed as shown in FIG. 18C in accordance with the desired size of the pull tab for the recording apparatus that is the final product. In the punching process, as shown in FIG. 18 (d), the punching is cut at an arbitrary position by a press 172 that moves up and down. The cut section is the recording device pull tab 170 shown in FIG.

  The present invention can be used as a pull tab for a recording apparatus in which a recording apparatus such as an HDD, an SSD, or a storage medium incorporated in an electronic processing apparatus such as a personal computer can be easily removed.
