Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an X-ray film processing device for taking out a photographed X-ray film from an X-ray film cassette and inputting ID information and the like.

[Background technology] An X-ray film cassette containing exposed X-ray film is inserted into an X-ray film processing device, and the lid is automatically opened while the X-ray film is shielded from external light. is taken out.

The taken-out X-ray film is placed upright on a holding roller, and ID information such as photographic information is exposed on one side of the film, and then sent to a developing device.

However, care has been taken to ensure that the X-ray film, when stored in the film cassette, comes into close contact with an intensifying screen pasted inside the cassette to reduce blurring of the image. Therefore, when the lid of the cassette is opened, the cassette sticks to the intensifying screen attached to the neck and is temporarily held up, then falls down after a while.

When it falls, it may be deviated from its normal position, so if you take it out and stand it up on the holding roller, I=D
When information is exposed, the ID recording section may shift and become closer to the center of the X-ray film, or conversely, all the information in the ID recording section may not be recorded.

[Measures of the Invention] Taking the above-mentioned facts into consideration, the object of the present invention is to obtain an X-ray film processing device that can accurately record ID information even if the X-ray film is misaligned.

[Summary of the Invention] In the X-ray film processing device related to the unreleased LJJ, while the X-ray film taken out from the cassette is placed on the holding roller and rotated in the extrusion direction of the X-ray film by the driving means, By moving the X-ray film to a predetermined position by means of a convergence means, the X-ray film can be quickly and precisely positioned in the width direction while eliminating the X-ray film from getting caught in the holding roller.

[Embodiment of the Invention] FIG. 1 shows an X-ray film processing apparatus according to the present embodiment, in which an X-ray film cassette 12 containing photographed X-ray film 10 is placed on a guide 14. ing. The cassette 12 is inserted into the processing apparatus from an unillustrated position, driven in the direction of the arrow, and then stopped in the state shown in FIG. 1, and this state flj is defined as the film take-out position.

A lid opening arm 16 is pivotally supported on the [,] side of the cassette 12 at the film removal position, and a suction cup 18 attached to the tip can suction the lid 12A of the cassette 12 with negative pressure. .

The lid opening arm 16 is rotated by being driven by a motor (not shown).

Further, in front of the cassette 12 at the film ejecting position (to the left in FIG. 1), a film ejecting arm 20 is attached to a shaft 22.
A suction cup 24 hangs down from the tip. This suction cup 24 is always maintained in a vertical position so that it can suction the X-ray film 10 in the cassette 12 with negative pressure.

A pair of take-out rollers 26 are disposed at the bottom of the film take-out arm 20, and the taken-out X-ray film l
It has a configuration in which O is held and sent out.

A guide (not shown) is provided behind these carry-out rollers 26 to guide the X-ray film in the ":" direction and hold it between the pair of holding rollers 28.

As shown in FIG. 2.3, these holding rollers 28 are connected to the output shaft of a motor 30 via gears 32, 34, so that they receive the rotational force of the motor 30. Therefore, these holding rollers 28 can make the fed X-ray film 10 stand upright on these holding rollers 28. In this example, the X-ray film lo
is installed vertically, and a guide 36 is provided to maintain this vertical state as necessary.

At the top of these holding rollers 28, width adjustment means 40, 42 are provided corresponding to both ends of the rollers.

In the width adjusting means 40, a guide plate 44 and a shaft rod 46 are guided by a linear movement opening parallel to the longitudinal direction of the holding roller 28, and correspond to the side surface of the X-ray film 10 that is set upright. This bushing rod 46 receives the force of the tension coil spring 48 in the direction of moving away from the X-ray film 1o.

Further, the end of the bushing rod 46 on the opposite side from the x&a film IO is in contact with an eccentric cam 52 having a rotating shaft 50 pivotally supported on the guide plate 44.

This eccentric cam 52 is connected to the output shaft of a motor 54. Therefore, as the motor 54 rotates, the tip of the bushing rod 46 can move the X-ray film lO toward the left in FIG. 2.3.

In the width shifting means 42, a bushing plate 56 shifts the width of the X-ray film 10 in a direction opposite to the width shifting means 40 in correspondence with the other side surface of the X-ray film 10.

A bracket 57 attached to the bushing plate 56 is guided by a guide bar 58 extending parallel to the longitudinal direction of the holding roller 28 to move. Further, this bracket 57 is secured by a screw 64 to a portion of a timing chain 62 that is wound around a pair of sprocket wheels 60. One of the sprocket wheels 60 is connected to the output shaft of a motor 66.

X-ray film placed upright on the holding roller 28] 0 is the third
The position indicated by the imaginary line in the figure is a reference position, and whether or not the X-ray film 10 is placed at this reference position is detected by a pair of photosensors 68 corresponding to the sides of the X-ray film 10. Further, ID information 72 is exposed onto the X-ray film 10 at this reference position from a light projection device 70 shown in FIG.

As shown in Figure fJS1, a pair of feed rollers 74 are disposed on the opposite side of the film take-out arm 20, and feed new, unused X-ray film from a magazine (not shown) to the cassette 12.

Next, the operation of this embodiment will be explained.

When the film 2A of the X-ray film cassette 12 is suctioned by the suction cup 18 and opened by rotation of the opening arm 16, the film take-out arm 20 suctions and lifts the exposed X-ray film 10 with the suction cup 124, and transfers it to the unloading roller. Send it to 26 rooms. In this case, when the cassette 112A is opened, the X-ray film that is temporarily lifted in close contact with the lid 12A falls into the cassette 12 and is then sucked by the suction cup 24. There is a high possibility that

The X-ray film lO with this positional shift is sent from the carry-out roller to the holding roller 28, and the tail end is transferred to the holding roller 28.
Even in the upright state in which the parts are in contact with each other, a positional shift in the width direction also occurs.

Therefore, the smoothing means 40, 42 are the butsch rod 46,
The bushing plate 56 is driven and moved in the width direction until the X-ray film 10 reaches the reference position shown in FIGS. 2.3 and is detected by the photosensor 68. During this width adjustment, the holding roller 28 is rotated by the motor 30 in a direction that pushes the X-ray film IO upward. Therefore, when moving towards the width
The end of the line film IO will not get between the holding rollers 28 and interfere with the width adjustment operation.

There are various width dimensions of the X-ray film lO, but since the convergence means 42 has a large stroke with the bushing plate 56 being guided by the guide bar 58, it can be used with any size of X-ray film. Even if there is, it is a sure way to bring people together.

When the X-ray film lO reaches the reference position, the light projecting device 70
ID information 72 is recorded. X-ray film lO
has already reached the reference position, the ID information 72 is recorded at a reliable position, and there is no possibility that it will overlap with other photographed parts or that part of the ID information will be missing due to positional deviation.

After recording the ID information, the X-ray film lo is sent to a developing device (not shown), a new X-ray film is loaded into the cassette 12, and after the lid 12A is closed, the cassette 12 is taken out from the processing device. .

[Effects of the Invention] As explained above, in the X-ray film processing apparatus of the present invention, while rotating the holding roller in the extrusion direction of the X-ray film with the X-ray film standing up on the holding roller ff, Since the width adjustment means performs the adjustment, information can be reliably recorded even if the X-ray film is shifted in the width direction.
