Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film loading device, and more particularly to a film loading device configured to be able to load a film package containing a plurality of sheet films into an image recording device or the like in a bright room. .

-In, X for subjects such as the human body! Radiographic film taken using this method is used for medical diagnosis and other purposes. Conventionally, when taking radiographic images using such an X-ray film, the X-ray film is loaded into a radiation imaging device in a light-shielded state, and the emulsion surface of this film is directly irradiated with X-rays. The image of the subject is recorded.

Incidentally, recently, a radiation image recording and reproducing system that uses a stimulable phosphor (exhaustible phosphor) to obtain a radiographic image of a subject has been developed and is becoming popular. Here, a stimulable phosphor refers to a stimulable phosphor that, when irradiated with radiation (X-rays, α-rays, β-rays, γ-rays, electron beams, ultraviolet rays, etc.), stores a portion of this radiation energy and later excites it with visible light, etc. A phosphor that generates stimulated luminescence according to the energy stored when irradiated with light.

The radiation image recording and reproducing system described above uses this stimulable phosphor, and records radiation image information of the human body, etc.
Recording is performed on a sheet having a layer made of a stimulable phosphor, and the stimulable phosphor sheet is scanned with excitation light such as a laser beam to generate stimulated luminescence, and the resulting stimulated luminescence is photoelectrically processed. An image signal is obtained by reading the image signal, and based on this image signal, it is output as a visible image to a recording material such as a photographic light-sensitive material, a CRT, or the like.

Here, when recording an image on a recording material, an image recording device, for example, an image output laser printer device is employed. This device stores photographic film, which is a recording material, through a magazine, etc., takes out the film one by one using a sheet-fed mechanism such as a suction cup, and then uses electrical signals obtained from a stimulable phosphor sheet to The film is configured to be irradiated with a laser beam modulated by the laser beam to record a predetermined image. Therefore, the film on which the new image has been recorded is conveyed into an automatic developing device, undergoes a developing process, and then is stored at a predetermined location and used for medical diagnosis, etc., if necessary.

Incidentally, in the image output laser printer device, when loading the film into the device, the film must not be irradiated with external light, similar to the conventional radiation image capturing device described above. This is because it will be exposed to light. Therefore, when loading film into an image recording device, etc.,
There is an inconvenience that the process must be carried out in a darkroom.

Therefore, in order to improve operability, it is strongly desired to load the film in a bright room, and various bright room loading methods have been proposed to make this possible. An example of this bright room loading method is disclosed in Japanese Utility Model Application No. 56-7931. This is shown in FIG.

On the other hand, the flange portion 166 of the rod 162 constituting the guide means 160 similarly abuts against the wall surface portion 214, and the rack 16
8 is displaced in the direction of the arrow (■) with respect to the i mounting table 102. Therefore, the pinion 170 that meshes with the rack 168 rotates in the opposite direction to the arrow, and the 17th arm 172 and the second arm 174 move toward the moving table 132. It is positioned by swinging in the direction away from the center.

In this way, the mounting table 102 is housed in the main body 100, and the stopper means 60 is driven as described above in the first embodiment. 12 device 102 to this main body part 10
Fixed within 0. Then, the mounting table 102 and the main body part 100
If the end of the film package 108 exposed to the outside is pulled in the direction of arrow H through the gap 212 defined between the movable stage 13 on which the film package 108 is placed
2 is displaced in the direction of the arrow (■) against the tensile force of the spring 135, and is supported by coming into contact with the locking plate 120 (see FIG. 8).

In this case, as shown in FIG. 9, the protrusion 140 provided on the movable table 132 is displaced in the direction of the arrow
30 is removed from the protrusion 140, the stopper member 126 swings vertically downward about the fulcrum pin 124 and releases the pressing action on the film package 108. Further, as shown in the tenth concave, pinions 144a and 144b rotate in the direction of the arrow via rack parts 142a and 142b provided on the moving table 132, and the arm 14
6a and 146b engage with the cut end portion folded back on the upper side of the film package 108 and are oscillated to extend the cut end portion in the horizontal direction.

Then, when the film package 108 is pulled out in the direction of arrow 1, the sheet films F stacked and housed in the film package 108 remain on the moving table 132 by the respective rollers 210 and 138.

When the film packaging body 108 is guided by the respective rollers 207a to 207d and taken out to the outside, the movable table 132 is displaced in the direction of arrow G by the tensile force of the spring 135, and the rotary body 130 moves toward the protrusion. 140, the stopper member 126 is in the position shown by the solid line in FIG. As a result, the end of the sheet film F placed on the moving table 132 comes into contact with the stopper member 126 and is positioned.

Next, under the driving action of the single-fed mechanism 80, the plurality of sheet films F stacked on the moving stage 132 are attracted one by one and transported to an image recording mechanism (not shown).

It is easily understood that the S1 mounting table 102 can be provided with a shutter member in the same way as the mounting table 34 described above.

As described above, according to the present invention, a removable mounting table is provided in the apparatus main body, a package in which a plurality of sheet films are stacked and stored is loaded on the mounting table, and the mounting table is placed inside the apparatus main body. The package is configured to be opened after being stored in the package.

Therefore, unlike in the past, there is no need to use a dedicated magazine, so the film loading operation can be simplified at once. Moreover, the film loading operation can be easily carried out in a bright room, and it is possible to provide a film loading device with extremely good workability. Also, if you attach the shutter member to the mounting table,
Even if unexposed film remains in the mounting table, there is an advantage that the mounting table can be suitably shielded from light and removed from the apparatus to perform, for example, maintenance of the apparatus.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
