[0004] These magazines are formed of various materials depending on the type, size and use of the photosensitive material to be stored. In general, the tubular body is often formed of a paper sheet material such as cardboard or paperboard, and the side plate is formed of a plastic resin from the viewpoint of imparting a certain degree of strength. FIG. 5 is an exploded perspective view of a general magazine, and FIG. 6 is a plan view of a side plate. Both open surfaces of the tubular body 1 made of paper are closed by side plates 2 made of resin. At this time, the end of the cylindrical body is fitted into the groove 6 provided in the side plate 2, and the ends of both end-face folded portions 11, 12 forming the slit-shaped outlet are also fitted into the groove 7, and further the cylindrical shape is formed. The magazine is completed by fixing the edge of the body to the groove 6 with an adhesive or the like. Here, the grooves 7 are provided at two upper and lower positions in consideration of the magazine assembling work (in order to use both the left and right sides when closing both the left and right open surfaces of the cylindrical body 1). The roll-shaped photosensitive material 3 housed in the magazine is rotatably supported by a bearing 5 provided integrally with the side plate 2, and is withdrawn from the slit-shaped outlet 4 for use.

As the tubular body 1, a rectangular tubular body formed by bending a single sheet of paper is usually used. Further, the cylindrical body 1 is integrally formed with a slit-shaped outlet (hereinafter, referred to as an outlet) 4 for the photosensitive material. The outlet 4 is formed by folding both end faces of the tubular body inward at least once. FIG. 7 shows a cross-sectional view of the cylindrical body. The upper end fold 11 for forming the outlet 4 is called an upper lip, and the lower end fold 12 is called a lower lip. Normally, the upper lip 11 is bent three times, and the third folding surface 11c is fixed to the upper surface 15 of the cylindrical body 1 with an adhesive or the like. The first folded surface 11a of the upper lip 11 is
And the slit-shaped outlet 4 are formed. FIG. 7a shows the lower lip 12 bent once, FIG.
b shows that the lower lip 12 is folded three times and the third folded surface 12
7c is fixed to the side surface 16 of the cylindrical body 1 with an adhesive or the like. FIG. 7c shows the lower lip 12 bent four times and the fourth folded surface 12d is bonded to the side surface 16 of the cylindrical body 1 with an adhesive. And so on.

As described above, both ends of the cylindrical body are fitted into the grooves 6 of the side plate 2 and fixed with an adhesive or the like. The ends of the upper lip 11 and the lower lip 12 constituting the drawer opening 4 are also fitted into the grooves 7 of the side plate 2. Therefore, the structure of the side plate 2 was complicated. 6, the side plate 2 is provided with a groove 6 into which the end of the cylindrical body is fitted and a groove 7 into which the ends of the upper lip 11 and the lower lip 12 are fitted.
As described above, if the structure of the side plate 2 is complicated, the inconvenience in the magazine assembling work, that is, the fitting between the end of the cylindrical body and the groove does not go smoothly, the workability is reduced, and in extreme cases, In some cases, there is a problem that the light-shielding property is deteriorated due to a failure in fitting.

As shown in FIGS. 7a, 7b and 7c, various types of structures of the outlet are employed. For example, an optimal structure is appropriately selected depending on conditions such as the type of the exposure apparatus, the size and the winding length of the photosensitive material stored in the magazine, and in some cases, several types of structures are employed. In such a case, it is necessary to provide a groove in the side plate in accordance with the structure of the outlet, and several types of side plates must be prepared according to the structure of the outlet, which is not preferable in terms of storage management and manufacturing cost.
