DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus provided after recording information of a plurality of X-ray imaging means on a film, and provided downstream.
As an example, the present invention relates to an X-ray film processing apparatus for sending a photosensitive material to a sorter for receiving the photosensitive material .

[0002]

BACKGROUND OF THE INVENTION Advances in X-ray diagnostic technology have been largely due to the development of related equipment and systems. In it,
There is an X-ray imaging system using CT. X by CT
The image signal of the line image is input to the imager of the recording means,
In IMEAS, printouts are performed as images. Here is Imma,
The above-mentioned image signal is output to a photosensitive material as an optical image, and the type sorting technique after the process of visualizing is mainly connected to a plurality of X-ray imaging means to an imager, and after outputting as an image, each X-ray imaging means There is no practical example of a system that sorts each X-ray image and stores it in a sorter. Conventionally, even if a plurality of X-ray imaging means are connected to an imager, when the image is developed and discharged, the entire number is the same as an integrated unit. However, it was difficult to determine which X-ray imaging unit the image was obtained from, and the resulting film was inconvenient in management.

[0003] Although there are many embodiments of sorter technology in the copier industry at the same time, the lack of a sorter at the medical site has good reasons. In other words, there has been no demand for X-ray images to create and distribute a plurality of copies for a plurality of documents.

[0004] The image of the affected area photographed on the X-ray film is an important material to be judged by the doctor, and the subtle shading contributes to the judgment of the doctor. There was no copying of multiple copies. Therefore, the sorter itself was unnecessary.

[0005] In addition, in X-ray photography, an image for identifying a patient is always or simultaneously printed on an X-ray film, so that the finished film is sorted by a special sorter. It was not necessary, and the handling was such that the person in charge could see it by looking at the film.

In recent years, however, X-ray imaging by CT has been put into practical use, and the captured image is processed as an electric signal to display an image in real time or to input the image to an imager and record the imager. Output to a photosensitive material or the like, and in an output form as required, it greatly contributes to diagnosis.

In such X-ray imaging using CT, the number of images taken for the same patient or affected area is large, and the number of images, imaging method and conditions may be completely different depending on each diagnostic purpose. It is no longer possible to manage the uniform identification of patients, and it is difficult to manually sort out the output film by connecting a plurality of X-ray imaging means to an imager. On the other hand, it is reliable. There is a situation where stable sorter development cannot be made in time.

[0008]

SUMMARY OF THE INVENTION The present invention satisfies the needs of a sorter in view of the situation at the medical site as described above, and when a trouble occurs in the sorter, does not stop the upstream side. It is an object of the present invention to provide an X-ray film processing system capable of relieving a film by collectively discharging and collecting the film in an accumulation unit.

[0009]

To achieve the above object, according to the Invention The X-ray film processing apparatus of the invention, the photosensitive material is developed which records the X-ray image formed by the recording means connected to the X-ray imaging means Developing means for exhausting and discharging, and the developing means
Receiving and guiding the photosensitive material discharged from
Switching means having a swingable guide plate for changing the direction,
Receiving and transporting the photosensitive material from the switching means,
Sorting processing based on the designated information from the X-ray imaging means
And a sorter, wherein the guide plate is provided to the sorter.
The guide path is shut off, and the sensor discharges from the developing unit.
After receiving and temporarily storing the optical material, the guide plate is cut off.
Swing by the operation of the switching means, to open the guideway,
The sorter that passes the photosensitive material and is located on the downstream side in the transport direction.
At the same time, the switching means is operated in accordance with the jam detection output from the sorter, and the guide plate is locked at a predetermined position to thereby guide the guide path to the sorter.
By blocking to form a photosensitive material collecting section, whether the developing unit
And the photosensitive material to be al discharged as integrated in the light-sensitive material stacking unit, characterized the kite.

Further, in the X-ray film processing apparatus according to the present invention, the sorter provided downstream of the switching means may be arranged based on designated information from the X-ray imaging means or by an instruction means for performing an arbitrary operation. The photosensitive material from the switching means is received.

[0011]

[0012]

A plurality of X-ray imaging means are connected to an imager, which is a high-performance recording means, and are recorded on a photosensitive material having high image reproducibility, particularly an X-ray film, which is a silver halide photosensitive material, and are developed. The workability is greatly improved by sorting and storing the information in the sorter according to the designated information from each X-ray imaging means. However, troubles in the sorter may be caused by fluctuation factors such as the size of the X-ray film and curling. Since it is inevitable, a sorter is provided with jam detecting means, when the jam occurs, the use of the sorter is interrupted, the switching means is locked in a predetermined position, a photosensitive material accumulation section is formed, and the subsequent film is accumulated. The subsequent film is relieved in such a manner that the subsequent films are collectively collected.

The provision of the instructing means for arbitrarily operating the switching means enables the use of the photosensitive material accumulating section which accumulates at once even when a jam does not occur as described above. instead of sending those interrupt processing while suspended holding the sorter sorter bins, stop to the photosensitive material stacking unit, thereby contributing to easy extraction, remove the film that integrates this manner, release the indicating means Then, the sorter function is restored again, and the sorting can be continued.

The designation of the sorter bin and / or the designation of the photosensitive material stacking section is carried out based on the designation information from the connected X-ray imaging means in order to efficiently sort different X-ray films for each X-ray imaging means. Specifically,
A specific code symbol is assigned to each X-ray imaging unit, the code symbol is sent to the recording unit together with the imaging information, and recorded in a predetermined position on the photosensitive material with a bar code or other easily readable symbol, and the sorter is controlled. The symbol can be read by a reading means provided in the middle of the photosensitive material transporting path, and the bin of the sorter can be designated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a layout diagram showing the entire configuration of an X-ray film processing apparatus according to the present invention, FIG. 2 is a cross-sectional view showing in detail from switching means of the processing apparatus to a sorter, and FIG. FIG.

First, as shown in FIG. 1, a plurality of CTs (CT
_{1 to} CT _n ) are connected to one recording unit, i.e., an imager 2, and the photosensitive material F discharged from the imager 2 is inserted into a developing unit 3 such as an automatic developing machine connected immediately thereafter. Present
The photosensitive material F processed by the image unit 3 is downstream of the developing unit 3.
The direction is changed by the switching means 6 integrated with the sorter 5 which is an example of the receiving means of the apparatus provided in the apparatus, and falls with the rear end down, temporarily stopped by the stopper 9, and then retracted by the stopper 9. Then, the direction is changed by the pair of rollers 10 and 11 to be directed upward, sent to the sorter bin 7 and stored.

Next, the operation of the switching means 6 will be described in detail with reference to FIGS.

The photosensitive material F discharged by the discharge roller 4 of the developing means 3 advances in the direction of the arrow, and the leading end thereof is moved upward along the guide plate 6a of the switching means 6, and the rear end of the photosensitive material F leaves the holding of the discharge roller 4. When the guide plate 6a is moved from the position A to the position B by the operation of the switching means 6, the rear end of the photosensitive material F leaning on the guide plate 6a also moves, and the lower guide 8 and the wall are moved. 13 and falls on its own weight, falls by its own weight, abuts against the tip of the stopper 9 at the C position, and temporarily stops.

The stopper 9 is actuated by a solenoid from position C to position D and moves to release the photosensitive material. By contact with the stopper 9, the lower edge of the photosensitive material is adjusted horizontally, and the photosensitive material enters the next roller pair 10 in an orderly manner. Roller pair 10, 11
The photosensitive material F conveyed in the step (a) travels upward and moves to the sorter bin 7.
Each is stored.

The operation of the guide plate 6a of the switching means 6 is as follows.
The guide plate 6a is rotatable around the hinge 12 by rotating the cam 14 driven by a motor. In this embodiment, the guide plate 6a can be located at two positions A and B. The photosensitive material F discharged from the developing unit 3 at the position A is received, temporarily stored, and moved to the position B so that the photosensitive material is dropped from the rear end. With this configuration, by locking the guide plate 6a at the position A, the photosensitive materials sequentially discharged from the automatic developing machine 3 can be accumulated without being sorted. In this case, since the sorter function is not involved at all, even if there is a trouble in the sorter, there is no problem in stacking it in the photosensitive material stacking portion formed by the guide plate 6a. Therefore, when jam in the sorter is detected by jam detection means (not shown), the control means controls the guide plate 6a so as to lock the guide plate 6a at the position A. The processing can be completed and accumulated in the photosensitive material accumulation section without wasting the photosensitive material .

Next, as described above, the photosensitive material is dropped by its own weight from the rear end, and the lower edge is brought into contact with the stopper so that the photosensitive material is aligned, so that the subsequent conveyance is performed in order and the reliability of storage in the sorter bin is improved. Could be increased. Here, the present invention
In this case, the type of downstream device is irrelevant,
Receiving means accepts jam of recorded matter
Then, the present invention is similarly applied to various types of problems.
it can.

[0023]

Since the X-ray film processing apparatus of the present invention is constructed as described above, the workability is improved by controlling the sorter in accordance with the designated information from the plurality of X-ray imaging means to perform sorting. Even if there is a problem, there is a merit that the photosensitive material and the recording information in process on the upstream side are not wasted, and a merit of improving reliability that can be sent to the sorter bin with the posture adjusted. I can do it.
