Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material loading magazine configured to load a plurality of photosensitive materials in a light chamber.

[0002]

2. Description of the Related Art For example, a cassette is used when photographing a radiation image of a subject such as a human body on a photosensitive material such as a film. In recent years, the work of loading the film into the cassette has been performed in a bright room. ing.

According to this conventional technique, a magazine containing a plurality of unexposed films in a light-shielded state is mounted in the film loading device. Then, when a cassette is inserted into the film loading device, only one unexposed film in the magazine is taken out by a sheet-fed mechanism including a suction plate and the like and automatically loaded into the cassette. The cassette loaded with the unexposed film is taken out from the film loading device and subjected to a predetermined radiation imaging operation. Further, such a film supply magazine for an image capturing apparatus as described in JP-A-64-44433, JP-A-1-105926, JP-A-1-105927, JP-A-1-98530, etc. can also be used. A chamber loaded magazine is used.

By the way, in this case, the work of loading a plurality of unexposed films in the magazine is performed in a light chamber, and substantially, the package in which the plurality of unexposed films are stored in a light-shielded state. A method is known in which, after loading the package into a magazine, one end of the package is cut and only the package is pulled out.

This is illustrated in FIG. 7, a main body 2a constituting the magazine 2 is loaded with a package 4 containing an unexposed film F in a light-shielded state. Next, the lid body 2b is closed to expose the one end portion 4a of the packaging body 4 to the outside from the guide portion 6 formed between the lid body 2b and the main body 2a. Next, after one end 4a of the package 4 is cut by a cutter, the other end (not shown) of the package 4 is pulled in the direction of the arrow, and only the package 4 is taken out to the outside.
The unexposed film F remains in the magazine 2. Here, the guide portion 6 is a portion through which the package 4 to be pulled out is guided and passes, and the slit-shaped groove portion 6 a opening to the outside of the magazine 2 and the first portion facing the inside of the magazine 2.
It is composed of a groove portion 6b and a second groove portion 6c which communicates with the groove portion 6a and the first groove portion 6b.

[0006]

However, in the above-mentioned prior art, as is clear from FIG. 7, the first groove portion 6b of the guide portion 6 of the magazine 2 is substantially unexposed film F.
Are formed in parallel with the stacking direction. Therefore, when the magazine 2 is tilted and attached to the film loading device and the unexposed film F in the magazine 2 is to be conveyed to the cassette, another unexposed film F adjacent to the unexposed film F that is directly taken out. In many cases, F falls into the first groove portion 6b and the film single-wafer operation becomes impossible. Therefore, it is pointed out that the film supply operation to the cassette cannot be efficiently performed.

The present invention has been made to solve the above-mentioned problems, and it is possible to reliably perform the work of supplying the photosensitive material without dropping the photosensitive material in the groove portion defined in the magazine. It is an object to provide a possible magazine for loading photosensitive material.

[0008]

In order to achieve the above object, the present invention stores a light-shielding body in which a plurality of light-sensitive materials are laminated in a light-shielding state in a magazine and then closes the magazine. In a photosensitive material loading magazine in which one end of the light shield is incised and the other end of the light shield is pulled out from the magazine body to load only the photosensitive material into the magazine, the magazine includes a body and a lid. And a non-linear light-shielding body pulling-out opening extending in a direction orthogonal to the direction of pulling out the light-shielding body is provided on one end side of the magazine.

[0009]

In the above construction, when the light shield is housed in the main body of the magazine and the lid is closed, one end of the light shield is exposed from the magazine to the outside. Therefore, when this one end is cut by an arbitrary means and the other end is pulled out from the magazine, only the photosensitive material is laminated and remains in the magazine.

Therefore, when this magazine is obliquely arranged in the radiographic image capturing apparatus and is to be used for radiographic image capturing, the stacked photosensitive materials do not enter the non-linear opening and the lower end side is aligned. The state is maintained, and the single-wafer operation is performed reliably and efficiently.

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 causes the shutter 7 to move.
The locking portion 82 of No. 8 is engaged with this, and this is moved to the left side in FIG. 5 against the elastic force of the spring member 84. Then, when the opening / closing member 98 is stopped at a predetermined angle position, the opening 80 of the shutter 78 reaches the position corresponding to the film insertion opening 76, and the unexposed film F is transferred to the cassette body 62a via the transport roller pair 70. It is dropped and fed between the cover and the lid 62b.

Then, the cassette body 62a is swung toward the lid 62b side through the arm 96 under the driving action of the rotary drive source 92, and the cassette 62 is closed. Therefore, while the unexposed film F is housed in the cassette 62 in a light-shielded state, the shutter 78 is urged by the elastic force of the spring member 84.
In FIG. 5, the film insertion port 76 is closed by moving to the right side. Therefore, the cassette 62 can be taken out from the cassette mounting portion 56 by releasing the suction action of the suction disk 108 and opening the shutter 59. At that time, outside 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
2 is loaded into a radiographic image capturing apparatus (not shown) and used for capturing a radiographic image of a desired subject.

Further, as another embodiment, as shown in FIG. 6, the film stoppers 32a and 32b can be constituted by tongue pieces which are formed in a flat bar shape so as to alternately project from the main body 12 and the lid body 14. . According to this structure, even if the magazine 10 is tilted, it is possible to prevent the unexposed film F stored in the chamber 18 from dropping from between the tongue-shaped film stoppers 32a and 32b.
