Description

DETAILED DESCRIPTION OF THE INVENTION The FiX-ray film imaging apparatus of the present invention, especially a large number of X! !
An I & storage system in which sheet film is loaded into a magazine at a time, the films are sequentially transferred one by one to a photographing stage, where they are photographed, and then removed from the photographing stage. For each body part, photographic record information such as the patient's name and date of photographing is always imprinted in the appropriate area outside the effective area of the XG image according to each size or body part without overlapping with the X4I image. This invention relates to an X-film photographing device that can be used.

In recent years, with the aim of saving labor, ``a large number of X-ray films are loaded into a magazine at once, the films are transferred one by one to the imaging stage, and after the X@photograph is taken, the films are removed from the imaging stage. X-ray film changers have become popular.

First, a conventional example will be explained using FIGS. 1 to 4.

Figure 1 shows a system using a film changer for chest imaging, Figure 2 is a cross-sectional view of the film changer, Figure 3 is a detailed view of a part of it, and Figure 4 shows the positional relationship of recorded information on films of different sizes. FIG.

31dXi in the figure! tube, 2 is the subject, 3Fi film changer, 4 is a stand supporting the film changer, and 5.6 is the first . Second size film, 7.8
are the first images that have not yet been photographed. A supply magazine 9 stores a second size of film, a receive magazine 9 collects photographed film, and IO stores photographed film.

A rectangular opening suitable for this purpose is provided. 11°11'
is a suction cup connected to an absorption pump (not shown).

The moving mechanism reciprocates between the illustrated position and the inside of the magazine. 122~] 2e#'i, rotating rollers that have the function of sandwiching and moving the film between them.

Reference numeral 13 denotes a guide plate that guides the film along the transport path. 14 is a front intensifying screen which is fixed to an X-ray transparent fixing plate 14' as shown in FIG. 3, and 15 is a rear intensifying screen which is fixed to a fixing plate 15' which is movable back and forth. . The intensifying screens 14 and 15 emit fluorescent light upon X1fs irradiation. 16 is a film stopper that supports the lower end of the sheet film, and 17 is a film scraping lever that has the function of scraping off the sheet film after shooting. 18 is a rotating roller, and 19 is a guide plate. A record card with the 20Fi test subject's name, photographing date, etc. written on it is inserted into the card holder 21 having a slit. 22 is a box-shaped part/material, inside which the record card #I is inserted. 23. Photograph the shadow gj! of the recording card illuminated by the lamp at an appropriate magnification. Film F on the stage.
A mirror 24 and a lens 25 are supported to be formed thereon. 26 is a lead plate attached to the fixed plate 14';
To prevent X-rays from being irradiated onto the area on the film where information is imprinted on the recording card. The film area where the lead plate 26 is set is not exposed to X-rays because it is not irradiated with X-rays.

Here, the effect of film feeding is as follows.

The suction cups 11 and 11' are sucked by a pump (not shown), and pick up the unphotographed films 5 or 6 one by one and sandwich them between the rollers 12a and 12b.

The rollers 12C, 12d, and 12eU rotate, and the film is transferred between the intensifying screens 14 and 15, and is stopped by a stopper (16).
．． Film from 15 companies is stuck in place, and the photo is taken in this state. By the way, at the same time as shooting
emits light, and the information on the recording card 20 is reflected by the mirror 24 in the direction of the film F, and is imaged onto the film F at an appropriate magnification by the lens 25.

After photographing is completed, the intensifying screens 14, 15 are opened again and the film stopper 16 is retracted in the direction of the arrow in the figure. Next, the scraper lever 17 moves in the direction of the arrow in the figure to nip the film between the rollers 1-8. The rollers 18 are rotating and transport the film into the receiving machine/9.

By the way, in the case of chest radiographs, the cabinet uses large-angle size (35
4J11X354111) and large country size (2790X
Since 354 mm (354 mm) films are often used, it is convenient for the film changer 3 to use large-angle and large-size films, for example.

Here, since the large four sizes are often used vertically, it is desirable to set the film on the film changer 3 vertically as well. Historically, due to the physique of the subject, it is desirable that the film be set in the center of the apparatus. That is, it is preferable to set it at the position indicated by the two-dot chain line in FIG.

On the other hand, it is desirable that the information on the recording card be imprinted at a position on the film that does not interfere with the photographed image of X@, and for example, the upper corner, such as position A in FIG. 4, is preferable.

By the way, in this case, if the film is large size, it will be in the upper right corner of the film and will not interfere with the entire X-ray image, but
L1 for films of different sizes, e.g. large-angle size.
The information on the recording card will be imprinted at a position that is inward by the difference in width between the large-4 size and large-angle size films, and in some cases may interfere with the X-ray image.

In addition, it may be desirable to imprint information on the recording card at different positions depending on different areas to be imaged. For example, if it is desirable to imprint the information on the recording card at the bottom center of the film for a certain area to be photographed, this may be discussed.

In view of the above points, the present invention provides an X-ray film camera in which the position where the photographed film information is recorded can be changed without overlapping with the X-ray image. ).
