Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an X-ray sheet film receive magazine into which photographed sheet films are sequentially fed, stacked and stored.

First, a high-speed film changer in which this X-ray sheet film receive magazine is used will be explained using FIG.

1 is a high-speed film changer body, 2 is a supply magazine for storing unshot film 3, and 4 is a high-speed film changer body.
5 is a receiving magazine for storing the photographed film 7; 6 is a film entry port; 8 to 13 are rollers for feeding the film;
14a and 14b are guide plates for guiding the film, and 15a and 15b are intensifying screens.

The unphotographed films 3 stored in the supply magazine 2 in FIG. 1 are passed one by one through the film outlet 4 by a mechanism not shown, and are sandwiched between rollers 8 and 9. The rollers 8 to 13 are rotated in the direction of the arrow in FIG. 1 by a mechanism not shown, and the film is sent between the intensifying screens 15a and 15b.

The intensifying screens 15a and 15b are brought into close contact with each other with the film sandwiched therebetween by a mechanism not shown, and a photograph is taken here.

When the photographing is completed, the intensifying screens 15a and 15b are opened, the photographed film is held between the rollers 11 and 12, and is stored in the receive magazine 5 through the film entrance 6 by the rotation of the rollers. There are two types of high-speed film changers, as shown in FIG. 1, in which the intensifying screen surface is placed perpendicular to the floor to take pictures, and in other cases the intensifying screen surface is placed horizontally on the floor to take pictures.

Next, a conventional receive magazine will be explained using FIG. 2.

In FIG. 2, reference numeral 16 indicates a floor surface of a film storage section in which photographed films are stacked and stored, and reference numerals 17 and 18 indicate film stoppers provided at the rear end and front end of the magazine, respectively.

When the photographed film passes between the rollers 11 and 13 and is stored in the receive magazine, the film is fed at high speed, so that the film hits the film stopper 17 at the rear end of the receive magazine and rebounds. At this time, depending on the surrounding environmental conditions and the properties of the film, the rebounded film may fly out of the receive magazine, or the rebounded film may act as a resistance to the entry of the next film, causing it to fall behind the next film. A phenomenon may occur where the end does not fit into the receive magazine.

The present invention has been made in view of this point. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a receive magazine in which exposed X-ray sheet films can be stacked smoothly.

The present invention will be explained below using FIG. Third
In the figure, 19 is a lever that is rotatably attached to a shaft 20, and 21 is attached to the tip of the lever 19, and it rotates freely in the direction of the arrow in the figure, but does not rotate in the opposite direction. It is a roller made of many materials. For example, a known one-way clutch is interposed between the roller 21 and the shaft. 22 is a leaf spring for pressing the lever 19 in the sheet film stacking direction. Further, the distance from the center of the roller 21 to the film stopper 18 is approximately the same as the length of the film.

Consider the case where the receive magazine shown in FIG. 3 is used in the high-speed film autochanger shown in FIG. 1.

Since the roller 21 freely rotates in the direction of the arrow in the figure, that is, in the direction in which the film enters, when the film is sent by the rollers 11 and 13 and enters the receive magazine from the entry port 6, the leading edge of the film is below the roller 21. Pass through and proceed to film stopper 17. At this point, the film tries to rebound, but since the roller 21 does not rotate in the opposite direction, this acts as a brake and stops. If the brake force is insufficient and the bicycle still bounces, the leaf spring 22 can be strengthened and the pressure of the roller 21 can be adjusted appropriately. Furthermore, even if strong resistance is generated between the film and the floor of the receive magazine or the film already stored in the receive magazine when the film enters the receive magazine due to the surrounding environmental conditions or the properties of the film, the roller 11 ,1
If the rollers 11 and 13 are positioned so that the rear end of the film that has left the film stopper 3 falls into the receive magazine, the distance between the center of the roller 21 and the film stopper 18 will be equal to the length of the film, as described above. Since the film is set at the same level as the roller 21, the film that enters the receive magazine is always bitten by the roller 21. In this way, once the film stored in the receive magazine is prevented from moving within the receive magazine, when the next film enters, it will not exert a force that pushes the next film back. There is no. However, only the topmost film needs to be fixed in the receive magazine; even if the films stacked below move, it will not affect the entry of the next film. Therefore, it does not need to be fixed.

Now, when developing photographed film stored in the receive magazine in an automatic processor, you can take out the film one by one by hand and develop it in the automatic processor, or you can use an automatic processor like the system shown in Figure 4. Take out the film one by one and insert it into an automatic processor.

In Fig. 4, 23 is an automatic developing machine, 24 to 27 are rollers for feeding the film, 28 is an auto feeder, 29 is a suction cup that attracts the film, and 30 is a supporter that supports the receive magazine and blocks light from the outside world. be.

In FIG. 4, after the receive magazine containing photographed film is inserted into the supporter 30 and the lid of the supporter is closed, the film entrance of the receive magazine is opened by means not shown.

Next, a suction cup 29 is moved by a mechanism (not shown) built into the auto feeder 28, and picks up the photographed films stored in the receive magazine one by one and feeds them into the automatic developing machine. When suctioning film with a suction cup, in order to reliably feed each film one by one into the automatic developing machine, the suction cup must always suction a certain part of the film, and therefore the film must be aligned in the receive magazine. If you set the receive magazine as shown in Figure 4, the film in the receive magazine will slide down under its own weight and the tip will end at the film stopper 18.
It's close to, and it's all right. If the film does not fall under its own weight due to stickiness, etc., before setting the receive magazine in the supporter,
Simply shake the magazine slightly with the film stopper 18 facing down. By the way, when the receive magazine shown in FIG. 3 is used in the above system, as mentioned above, the roller 21 provided in the receive magazine presses the film so that it does not slide toward the entrance. Even if the receive magazine is set as shown in FIG. 4, the leading edge of the film is not aligned with the film stopper 18, which causes poor suction. Further, since the roller 21 acts as a resistance, this also causes poor suction and scratches on the film.

Even if the film is taken out one by one by hand without using the system shown in FIG. 4, the roller 21 will still act as resistance and the film will be scratched.

In order to solve the above-mentioned disadvantages, the receive magazine according to the present invention shown in FIGS. 5 and 6 has the following features:
It has means for releasing the pressure of the roller 21 against the floor surface 16. In FIG. 5, 31 is a projection provided on the lever 19, 32 is a shaft rotatably attached to the upright side of the film storage section, 33 is attached to the shaft 32, and the tip thereof is attached to the projection 31. This is a plate material that engages with the shaft 32 and causes the lever 19 to swing as the shaft 32 rotates.

FIG. 6 is a perspective view of the AA cross section of FIG. 5 viewed diagonally from above, 34 is a lever attached to the shaft 32, 35 is a push button whose tip is protruding outside the magazine; 35 is pushed in the direction of the arrow in FIG. 6, the lever 34 is pushed and the shaft 32 rotates in the direction of the arrow.
is lifted, and the pressing force of the roller 21 against the floor surface 16 is released.

The receive magazine shown in Figures 5 and 6,
When used in the system shown in FIG. 4, when the lid of the supporter 30 is closed,
A projection is provided that automatically pushes the push button 35 of the receive magazine.

This allows roller 2 in the receive magazine to
1 is released, the roller 21 does not interfere with the film feeding operation of the suction cup 29. Further, when taking out the film by hand, it is sufficient to do so while pressing the above-mentioned push button. Although two rollers 21 are provided in FIG. 6, even just one roller has a considerable effect.
It is also clear that more than two may be provided.

As described above, if the receive magazine according to the present invention is used in the high-speed film changer shown in FIG. 1, the film can be inserted into the receive magazine reliably and there will be no film feeding errors. Furthermore, when developing the photographed film stored in the receive magazine using the system shown in Figure 4, or when taking the film out of the receive magazine by hand and inserting it into an automatic processor, the film on the roller By releasing the bias in the stacking direction, there is no possibility of scratches on the film.
