Description

[Detailed description of the invention] This invention is an X-ray photographing device that connects a cassette-less type photographing device and an automatic developing device in order to automatically supply film during X-ray photography and develop the film after photography. It is related to.

This type of X-ray imaging device can automatically perform everything from supplying film to development during X-ray photography without requiring any human intervention, so it is advantageous in that it saves labor and can obtain X-ray photographs in a short time. It is.

However, if a transport problem occurs during maintenance or inspection such as replacing the developer of the automatic processor, or during the transport route of the photographed film from the photographing device to the automatic processor, the X-ray imaging function may of course be stopped. However, this had the inconvenience of affecting the patient's treatment and doctor's diagnosis.

This invention solves the above-mentioned problems. In an X-ray imaging device that connects a cassette-less imaging device and an automatic developing device, the exposed film is taken out on the transport path for the exposed film from the imaging device to the automatic developing device. A receive magazine can be loaded therein, and in the event of a problem with the automatic developing device or the film transport path leading thereto, the photographed film from the cassetteless photographing device can be stored in the magazine.

The drawings will be explained below. In Figure 1, 1
is a dark box for a cassette-type photographing device in which the film changer unit, etc. is housed, and also serves as a table holding frame. 2 is a table on which a subject is placed, 3 is a subject, 4 and 5 are film magazines that store unphotographed films attached to dark box 1, 6 is a film suction conveyance unit, 7 is a feed roller, and 8 is an intensifier. Paper-equipped film carrier,
Reference numeral 9 denotes a delivery roller, 10 a film conveyance section for an automatic processor, 11 an automatic processor, and 12 a receive magazine for storing photographed film, which is removably engaged with the dark box 1 via a fastening mechanism (not shown). When installed in the dark box 1, the film insertion opening 10' is located in the film transport path from the feed roller 9 to the film transport section 10 for an automatic processor.

Figure 2 is a detailed view of the 15th circle in Figure 1.
Reference numeral 13 denotes a magazine holding frame which is provided in a continuous manner with the insertion opening 1' of the receive magazine 12 formed on the side wall of the dark box 1, and which guides the insertion of the receive magazine 12 into the dark box 1 and holds it during installation. ,1
4 is a light-shielding lid that also serves as a guide plate for the film.
In the embodiment, the light-shielding lid 14 has its lower end pivotally attached to the dark box, and is biased counterclockwise by a biasing mechanism such as a spring (not shown). Therefore, when the receive magazine 12 is not installed (inserted) in the dark box 1, the light-shielding lid 14 is in the solid line position in FIG. 13' is closed to shield the dark box 1 from light, and when the receive magazine 12 is installed (inserted) into the dark box 1, the contact of the receiving magazine 12 resists the biasing force of the biasing mechanism and moves along the second chain double-dashed line. Rotate into position.

Next, to explain the situation in which the film moves in the dark box 1 during X-ray photography, the sheet film (unexposed film) stacked in the supply magazines 4 and 5 is sucked by the film suction conveyor 6. and reaches the feed roller 7. Depending on the selected film size at this time, either film 4 or 5 is attracted and moved. The film that has passed through the feed roller 7 is
A carriage 8 equipped with an intensifying screen is reached, which, depending on the film size, moves to the respective irradiation center and receives the X-ray irradiation. Next, the back surface 14' of the light-shielding lid 14 passes through the feed roller 9.
The film is guided to a film conveying section 10 for an automatic developing machine, and further enters an automatic developing machine 11 where it is developed.

If the automatic processor cannot be used for maintenance or inspection such as replacing the developer, or if there is a problem in the film transport path between the feed roller 9 of the photographing device (dark box) 1 and the automatic processor 11. When this occurs, the receive magazine 12 is inserted into the insertion slot 1' and mounted and held in the dark box 1 via the magazine holding frame 13. At this time, the film insertion opening 12' of the receive magazine 12 is located on the film transport path from the photographing device to the automatic developing device. As a result, the photographed film fed out from the feeding roller 9 is stored in the receive magazine 12, so that photography can be continued without any hindrance. In this case,
After shooting, the receive magazine 12 is placed on the magazine holding stand 1
3 and the photographed film stored therein is developed in the conventional manner. When the receive magazine 12 is not set, the insertion opening 1' is closed with a light-shielding lid 14 attached as shown by the solid line in FIG. I will guide you through the films up to Part 10.

With this invention, when a trouble occurs in the automatic processing machine direct connection system, it can be diagnosed and
The photographing work can be continued without interruption and without any hindrance to the work. Further, the present invention has very great practical effects, such as being able to inspect, adjust, or use only the photographing device without using the film transport section for an automatic developing machine or an automatic developing machine.
