DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray film supply magazine and an X-ray film storage magazine mounted on an X-ray fluoroscopy apparatus or an X-ray fluoroscopy table (hereinafter referred to as an X-ray fluoroscopy table). In particular, the present invention relates to a film magazine for an X-ray fluoroscopy table, which prevents a trouble in a photographing operation.

[0002]

2. Description of the Related Art FIG. 7 is a side view of an X-ray fluoroscopic table viewed from the body axis direction of a subject. A base 1 is installed on the floor, and a table support frame 2 is attached to the base 1, and is supported so as to be rotatable about an axis parallel to the paper surface.

[0003] The table 4 is supported by the support frame 2,
The subject 5 is placed and can be moved in a direction perpendicular to the paper surface. A cassette-type X-ray radiographing device 6 is attached below the table. In this X-ray photography system,
A supply magazine 11 for storing about 50 to 100 unphotographed X-ray films in a stacked state and a storage magazine 16 for storing photographed films are incorporated. Also, there is an image intensifier 7 and X-rays from the X-ray tube device 3
It is provided at the radiation center of the line, and in a normal state, a fluoroscopic observation is performed by the television camera 8 and a television monitor (not shown).

Referring to FIG. 8, an outline of the X-ray flash apparatus 6 will be described. The X-ray copying machine 6 sets a plurality of unphotographed films in the supply magazine 11, takes out one film by the suction pad 12, is guided by the film guide 13 a by the conveyance roller 15 a, and is conveyed to the film holder 14.
When the X-ray irradiation button is pressed, the film holder 14 moves to the photographing position, and X-ray irradiation is performed.
The sheet is discharged by a film transport roller 15b photographed from the printer and guided by a film guide 13b and stored in a storage magazine 16.

FIG. 6 is a perspective view of a supply magazine 11 or a storage magazine 16 (hereinafter, simply referred to as a magazine) used in the above-described rapid-moving apparatus. In the figure, reference numeral 23 denotes a magazine cover. When loading the film, the dark room is illuminated, and the lid lock lever 26 is pushed up in the direction E while the lid opening / closing lever 31 is lightly pushed down. Opens in the opening direction. Next, darken the dark room. The unphotographed film is taken out of the case, and a predetermined number (for example, 50 to 100)
Are loaded into the supply magazine. Next, the opening / closing lever 31
Gently, and push in the direction from arrow B to full. Thereby, the lid 23 is closed. At this time, it is confirmed that the lid opening / closing lever 31 is securely hooked on the lid lock lever 26. Next, the supply magazine is pushed into the rapid-moving apparatus by grasping the handle 24 of the magazine by hand.
The guide groove 50 provided in the camera 1 is fitted and guided by a guide rail provided in the rapid-moving apparatus.

When the supply magazine 11 is to be taken out of the rapid-release apparatus, when the user presses the mounting release button 40, the leading ends of the mounting levers 41 and 42 projecting to the left and right of the magazine retract.
The engagement with the quick-release device is released, and the magazine can be taken out. A similar configuration is employed for the storage magazine.

[0007]

In the above-mentioned prior art, the lid opening / closing lever 31 of the X-ray film supply magazine and the storage magazine, and the lock release push button 40 for mounting the magazine to the rapid-moving apparatus are exposed to the outside of the rapid-moving apparatus. Therefore, there is a possibility that the cover of the magazine may be opened or the magazine may be detached when it comes into contact with an external object, for example, the hand or foot of the operator of the rapid-release device. An object of the present invention is to solve the above problems.
