Abstract

PURPOSE:To surely fix a fitting member even if a hollow cylinder is made of a hard material by providing a fitting member equipped with plural radially extending nails whose top ends are positioned outside the inner of the hollow cylinder in a non-fitting condition and which can freely elastic-deform in a radial direction and engage with engaging parts. CONSTITUTION:The fitting member 15 has 12 nails 18 radially extending from a substrate 17. These nails are formed in such a way that their cross sections are almost trapezoidal, and can be freely elastic-deformed in the radial direction. Curved surface parts 19 are formed on the top end parts of the nails 18 so as to smoothly insert the nails into the hollow cylinder 14. The top end surfaces of the nails 18 are positioned outside the inner of the hollow cylinder 14 in a non-fitting condition without no load is applied, and are prevented from coming into contact with a side plate 11 when the core 13 rotates, so that, they are positioned inside the outer of the hollow cylinder 14. Thus, since the top ends of the nails 18 can be positioned outside the outer of the hollow cylinder 14, the pressing power of the nails 18 can be increased, and the fitting member can be surely fixed.

個所へ送り出していた。In order to load a rolled photosensitive strip into a hardware device such as a printer in a bright room in a phototypesetting device, etc., the rolled photosensitive strip is stored in a light-shielded container, and the photosensitive strip is This was done by loading the container into the printer, and then pulling out the photosensitive strip from the outlet and sending it to a predetermined location in the printer.

４に感光性帯材３が巻かれた巻芯５が遊嵌されている。Conventionally, as shown in FIG. 7, such a photosensitive strip container has a cylindrical body 1 provided with a side plate 2 that closes openings at both ends, and a photosensitive strip is placed inside the side plate 2. A core holder for rotatably supporting the core holder is formed with a portion 4, and a core 5 around which a photosensitive strip 3 is wound is loosely fitted into the core holder.

ことができなくなるものであった。In such a photosensitive strip container, since the winding core 5 is loosely fitted into the core holder of the side plate 4, the photosensitive strip 3 is suspended in the air, and the winding loosens due to vibration etc. during transportation. The resistance increases when pulling out the photosensitive strip 3 from the outlet.
This caused slips in printers, etc. Furthermore, if this drawing resistance becomes too large, it becomes impossible to draw out the photosensitive strip.

１−１２１８５２号公報）。Therefore, as shown in FIG. 8, the present applicant used a hollow cylindrical body 6 and a fitting member 8 having a protrusion 7 with a triangular cross section formed on the circumferential surface, and attached the protrusion 7 to the hollow cylindrical body 6. We have proposed a container in which the core is formed by being fixed together by press-fitting, and this fitting member 8 is fixed to the side plate during transportation and rotatable relative to the side plate during use (Japanese Patent Application Laid-Open No. -121852).
