The projection lens 3
An exposure stage 5 composed of horizontal adsorption plates 4A and 4B is arranged above the exposure stage 5.
A movable arm 7 supported by the body 1 by a base shaft 6 and capable of raising and lowering is located at the lower part of one side of the movable arm 7, and guide plates 8A, 8B and a guide roller 9 are supported by the movable arm 7. The movable arm 7 is placed in the position shown by the imaginary line when the photosensitive sheet x is fed or discharged, and therefore the guide plate 8^,
A passage for the photosensitive sheet x is formed between the guide roller 8B and the suction plates 4A and 4B. Also,
When taking an image with the cathode ray tube 2, the movable arm 7 is brought down to the position shown by the solid line and retreated out of the screen of the taking lens 3. In this case, the photosensitive sheet x is placed in the vacuum box toa.
, suction play due to vacuum pressure applied to ton) 4
It is adsorbed and held on the surfaces of A and 4B.

Photosensitive sheets x in a supply magazine 12 mounted on a supply stand 11 on the upper side of the machine body 1 are taken out one by one into a supply path 14 by a vacuum suction head 13. (Said adsorption play)
Supply path 1 formed horizontally adjacent to 4A and 4B
4 is constituted by a plurality of pairs of reversible roller groups 15A and 15B, and a reversible feed roller IB is located between the suction plates 4A and 4B in the same horizontal plane as these plates, By this rotation of the feed roller 1B, the photosensitive sheet x is taken into the exposure stage 5 and removed from the same stage.

Further, an inclined take-out belt device M17 is located below the supply path 14, and the exposed photosensitive sheet X is collected by the take-out belt device 17 into a collection magazine 18 located below the supply magazine 12. . That is, the extraction bell l
``!m1tt?'' has a stretchable endless belt 21 stretched between a drive roller 19 and a driven roller 20, and an auxiliary roller 22 facing the intake port 18a of the collection magazine 18 is attached to the drive roller 18. The driven roller 20
The upper movable shaft 23 supporting the can be moved up and down by an electromagnetic solenoid or other up and down movement mechanism (not shown).
When the photosensitive sheet X is supplied from the supply magazine 12 toward the exposure stage 5, the upper movable shaft 23 is placed in the lowered position shown by the solid line, and the exposed photosensitive sheet X is collected into the collection magazine during the day. At this time, the upper movable shaft 23 is placed in the raised position shown by the imaginary line, the driven roller 20 is intervened in the supply path 14, and the endless upper belt 21 is driven in the direction of the arrow.

By the way, in an image capturing device with such a structure,
X-ray film with sizes such as 14" x 17" (cut in half), 14" x 14" (large angle), and 14" When the photosensitive sheet (photosensitive sheet) X stored in
, and it may become impossible to accommodate the subsequent collection magazine 18. For this reason, conventionally, a collection magazine is designed for the largest size photosensitive sheet to be used so that it can accommodate photosensitive sheets x of any of these sizes, and the intake port of the collection magazine 18 is In such a way that the side end 18b is lower, the rear end of the photosensitive sea) Either the collection magazines 1B are always aligned with the intake side end 18b, or a dedicated collection magazine 1B for each size is used to prevent the preceding collection magazine 1B and the subsequent collection magazine IB from colliding with each other.

However, although the former measure has the advantage of being able to store a large number of collection magazines 18 in a stacked manner,
The collection magazine 18 is tilted to the ejector belt device 1 for installation.
7, which tends to make the overall configuration of the image capturing device difficult. Also, according to the latter measures.

On the other hand, the direction of the take-out belt device 17 becomes more flexible, but when storing a large number of collection magazines 18 in a stacked manner, it is difficult to secure a storage space because a plurality of types of collection magazines 18 of different sizes are mixed together. .

1. Object of the Invention 1. An object of the present invention is to take into consideration the problem of the collection magazine of the conventional image capturing device as explained above, and to provide a method in which the width direction dimensions of the photosensitive sheets used are the same as described above. In view of the facts, one collection magazine can be used for multiple sizes of photosensitive sheets, and the subsequent photosensitive sheets will not collide with the rear end of the previously stored photosensitive sheets, making it difficult to store them. It's about getting the structure.

1. Structure of the Invention - To achieve this object, 1. the present invention captures an image displayed on a display device such as a cathode ray tube on a photosensitive sheet such as an X-ray film, and collects this photosensitive sheet into a collection magazine. In the photographing device, a stopper capable of blocking the front end of the photosensitive sheet to be collected is housed inside the collection magazine main body, which is manufactured to a size that can accommodate the maximum photosensitive sheet used, and can be used at position tA. It is proposed that a small-sized photosensitive sheet be held by a stopper whose position is adjusted according to the size of the photosensitive sheet.

One Embodiment - Details of an embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The first drawing is a cross-sectional view of the first embodiment of the present invention, and the collection magazine 18A in the first illustrated example has lengthwise dimensions and a width that can accommodate the largest size of photosensitive sheet X used in an image capturing device. The collection magazine main body 18c is manufactured in the direction dimension (perpendicular to the plane of the paper in FIG. 1), and the rear end 18b of the collection magazine main body 18c has an intake port for receiving the photosensitive sheet (X) from the take-out belt device 17. 18a is formed. This intake port 18a can be covered with an opening/closing lid 18d in order to prevent the photosensitive sheet (X) contained therein from being exposed, just as in the conventional case.

The bottom wall 18e of the collection magazine main body 18c is
A plurality of positioning holes 23 are formed that are aligned in the width direction of the collection magazine 18A, and a stopper bin 24 (shown as a stopper bin 24) is inserted into the positioning hole 23 corresponding to the size of the photosensitive sheet x to be stored in the collection magazine 18A. By inserting and fixing, a specific photosensitive sheet x can be stored in the collection magazine 18A.

Since the recovery magazine 18A according to the first embodiment has the above-described structure, if the positioning hole 23 is formed at a position corresponding to the size of the photosensitive sheets X to be accommodated, the previously accommodated photosensitive sheets This can prevent the photosensitive sheet x from becoming an obstacle and making it impossible to accommodate the subsequent photosensitive sheet X. That is, the size of the X-ray film used as a photosensitive sheet or
14" x 17# (half cut), 14" x 14" (large angle),
Since the size is 14"Xll" (large size), the width direction dimensions of these photosensitive sheets x are all the same, and only the length direction dimensions are different, so the positions according to these length direction dimensions are If the positioning hole 23 is formed, the leading end of the photosensitive sheet x fed by the take-out belt device 17 can be stopped by the stopper bin 24, so that the preceding photosensitive sheet x stored in the collection magazine 18A can be It stops in a state where it is locked by the stopper bin 24 as shown in FIG. Therefore, when the subsequent photosensitive sheet X is fed into the collection magazine 18A, the rear end surface of the previous photosensitive sheet 2 is the leading edge of the subsequent photosensitive sheet x! 1 can be prevented from colliding and becoming difficult to accommodate. In addition, in order to correspond to the size of the photosensitive sheet X accommodated in the illustrated example structure, the stopper bin 24
There is no need to point out that it is only necessary to replace the holder with another positioning hole 23. Of course, in the collection magazine 18A of the present invention, one collection magazine 18A can accommodate all sizes of photosensitive sheets) Since it is possible to prepare a plurality of collection magazines 18A having the same size, storage and transportation become easy.

Figure i2 is a sectional view corresponding to Figure 1 of the second embodiment of the present invention, and the same reference numerals are given to the same structural parts as in Figure 1. The feature of the second embodiment is that a stopper 24A having an "L"-shaped cross section is used in the collection magazine 18B instead of the stopper bin 24 described above, and the photosensitive sheet (X) taken in from the intake port 18a by this stopper 24A is to stop. Since this stopper 24A is replaced and fixed in the positioning hole 23A depending on the size of the photosensitive sheet x used, it is possible to obtain the same effect as described with reference to FIG. 1.

It goes without saying that the invention is not limited to the above-mentioned embodiments, and that the scope of the present invention also includes a stopper whose position can be adjusted by external operation.

-Effects of the Invention- As is clear from the above explanation, according to the present invention, the photosensitive sheet stored earlier in the collection magazine does not become an obstacle and make it difficult to store the subsequent photosensitive sheet. Since a plurality of collection magazines having exactly the same external dimensions can be used, storage and transportation are facilitated.
