The film loading device 50 to which the magazine 10 according to the present embodiment is mounted is basically configured as described above, and the operation thereof will be described next.

The operation of simultaneously accommodating a plurality of unexposed films F in the magazine 10 in a bright room will be described. First, the lid 14 is opened, and the package 16 is loaded into the chamber 18 of the main body 12. A plurality of unexposed films F are accommodated in the package 16 in a light-shielded state. Package 16
Is mounted on the film stopper 22a and the light blocking member 20a and extends to the outside, and the other end 16b of the package 16 is also mounted on the film stopper 22b and the light blocking member 20b and extends to the outside. I do.

Next, the cover 14 is closed to shield the interior of the chamber 18 from the outside. In this case, one end 16a of the package 16 is meshed and locked by the light shielding members 20a and 20c, and the other end 16b is also meshed and locked by the light shielding members 20b and 20d.

Next, after cutting one end 16a of the package 16 with a cutter (not shown) and pulling the other end 16b outward, the package 16 becomes light-shielding members 20b and 20d.
As a result, the unexposed film F is pulled out from the opening 21 while being left in the chamber 18.

Therefore, the package 16 can be easily taken out without impairing the light shielding performance.

After the unexposed film F is stored in the magazine 10, the magazine 10 is mounted on a magazine mounting section 54 of the film loading device 50. In the magazine mounting portion 54, the shutter member 40 of the magazine 10
Is opened, the sheet body sheet feeding mechanism 64 is driven.

The unexposed film F is supplied to the guide plates 68a and 68b and the transport roller pair 70 side while a plurality of sheets are blocked.

Here, the magazine 10 is inclined with respect to the vertical direction, and the A side of the magazine 10 is disposed below. Therefore, even if another unexposed film F adjacent to the unexposed film F directly adsorbed to the suction disk 66 moves to a position where it engages with the groove 30 defined between the film stoppers 22a and 22c. The other unexposed film F can be prevented from falling into the groove 30 by the film stoppers 22a and 22c. This is because even if the unexposed film F is curled, it is a convex or concave curl and does not curl in a wavy manner. As a result, an unexposed film F caused by the sheet unit sheet mechanism 64 can be prevented from being defective, and the unexposed film F can be reliably and efficiently sent out to the cassette 62 side. . On the other hand, in the cassette mounting section 56, the cassette 62 is in a waiting state in an open state via the cassette opening / closing means 90. That is, the lid 62b of the cassette 62 is positioned and held on the cassette holding member 106 under the suction of the suction disk 108, and the locking member 104 is engaged with the main body 62a of the cassette 62. Then, the link piece 94 rotates under the driving action of the rotary drive source 92, and the opening / closing member 98 swings and displaces integrally with the cassette body 62a under the pulling action of the arm 96 that engages with the link piece 94. Is opened in a direction away from the lid 62b.

Here, when the opening / closing member 98 swings about the support pin 100 as a fulcrum, the locking member 104
8 and is moved to the left in FIG. 5 against the elastic force of the spring member 84. Then, when the opening / closing member 98 is stopped at a predetermined angular position, the opening 80 of the shutter 78 reaches a position corresponding to the film insertion port 76, and the unexposed film F is moved to the cassette body 62a via the pair of conveying rollers 70. And is fed between the cover and the lid 62b.

Next, the cassette main body 62a swings toward the lid 62b via the arm 96 under the driving action of the rotary drive source 92, and the cassette 62 is closed. For this reason, while the unexposed film F is housed in the cassette 62 in a light-shielded state, the shutter 78 is moved by the elastic force of the spring member 84,
In FIG. 5, the film insertion opening 76 is closed by moving to the right side. Therefore, the cassette 62 can be taken out of the cassette mounting section 56 by releasing the suction action of the suction plate 108 and opening the shutter 59. At this time, external light is not unnecessarily irradiated to the upper side of the housing 52, that is, the room in which the magazine 10 is loaded.

Cassette 6 loaded with unexposed film F
Reference numeral 2 is mounted on a radiation image capturing device (not shown) and used for capturing a radiation image of a desired subject.

As another embodiment, as shown in FIG. 6, the film stoppers 32a and 32b can be formed of tongue pieces which are formed in a flat bar shape from the main body 12 and the lid 14 and alternately project from each other. . According to this configuration, even if the magazine 10 is tilted, the unexposed film F stored in the chamber 18 can be prevented from falling from between the tongue-shaped film stoppers 32a and 32b.
