Description

[Detailed Description of the Invention] This invention includes an automatic developing device for developing X-ray film that has already been photographed, which is rotatably mounted on a cassette telephoto copying device.
This invention relates to an X-ray fluoroscopic imaging table that performs imaging and development online.

By integrally connecting an X-ray fluoroscopy table and an automatic developing device,
The ability to automatically process the development of already shot cut film online will further promote labor savings and efficiency improvements in Xi fluoroscopy using a cassette-less quick-shooting device. There is a growing demand for a device that does this. However, in a conventional device that combines a cassette-less snapshot device and an automatic developing device, the fluoroscopic imaging table has to be raised and lowered in order to change the patient's body position when diagnosing the patient.
Alternatively, although the quick copying device is not in a fixed position due to movement of the quick copying device itself, the automatic developing device is usually placed in a fixed position such as on the floor due to its function and structure. For this reason, in the conventional connected devices mentioned above, photographed film could only be fed into the automatic developing device when the fluoroscopic photographing table was in a restricted position (generally in a horizontal position). This is inconvenient in that some of the above-mentioned feeding operations still require manual labor.

This invention has been made in view of the above-mentioned current situation, and is intended to eliminate the drawbacks of conventional devices.In other words, a cassette telephoto speed copying device is provided with a film feeding mechanism for sending out a cut film that has already been shot to the outside, An automatic developing device for receiving and developing the film is suspended so as to be rotatable, and the bed on which the subject is placed is raised, for example, by its own weight or by appropriate vertical restraint means. The present invention relates to an X-ray fluoroscopic photographing table characterized in that the automatic developing device is always kept in a vertical position regardless of the inclination of the photographic device when it is tilted. With this configuration, the photographed film can be fed into the automatic developing device in a vertical position in any posture or position of the photographic device, such as when the photographic device is tilted due to the raising and lowering of the bed on which the subject is placed, or when the position of the photographic device itself is moved. The aim is to provide a labor-saving, high-efficiency device that enables photography and development to be completed online.

The present invention will be explained in detail below with reference to the drawings.

FIG. 1 shows an X-ray fluoroscopic imaging table (1) according to an embodiment of the present invention.

Rotate and assume an inverted position.

The pillars (7) attached to the top plate (5) and the side support legs (7)
An X-ray tube device (8) is supported on the top, and this X-ray tube device (8) is movable in the longitudinal direction of the top plate (5), that is, in the arrow (C) with respect to the bed part (2). (Figure 6 is an example of this, moved to the left end) (dotted chain line σC)
is the central axis of the X-ray radiation cone. The support leg (7) aligns and supports the tube axis (9C) of the image tube (9) on the X-ray radiation cone center axis (XC) as shown in FIG.
The X-ray tube device (8) and the image tube (9) are integrated into one body. In addition, the top plate (5) has a top plate slide mechanism (5).
S) allows the bed portion (2) to be slid by a predetermined stroke in the longitudinal direction and the width direction. (7AX7A') is an arm extending from the support leg (7), and holds a cassette-less copying device 00 (indicated by a dotted line in FIG. 1), which will be described below. Between the above (7AX7A'), the cassette telephoto copying device 00 whose tip (10) is exposed penetrates through the support leg (7) and is provided with a cut film transport/receiver outer box (10B) on its back, and stands upright on its upper surface. The supply magazine 0]) is removably inserted. The outer box of the sending/receiving part above (
For example, a rod-shaped roller bearing (1) is provided as a rolling bearing at the end (10B), and the suspended automatic developing device 0, which is the main part of this invention, is connected to the gap C from the floor (3) through this.
) and is rotatably supported. The internal structure of the above-mentioned snapshot device θ will be explained with reference to FIG. The photographic cut film (Fl) in the supply magazine θ]) is guided (Fl) by a film ejecting mechanism a4 such as a suction cup.
and the standby position, that is, the top plate (
5) Film carriage αη located away from directly below
will be sent to. In this state, fluoroscopy is performed, and then the carriage αη is moved in the direction of the arrow (1), and the top plate (5) is moved.
After stopping at the imaging position directly below, X-rays are emitted and imaging is performed. When the photographing is completed, the film carriage CIη moves in the direction of the arrow (θ) and conveys the photographed cut film (F2) to the original standby position. Next, guide (g) (
g)・The above-mentioned automatic developing device@ The cut film falls inside due to its own weight.

In Figure 2, the bed part (2) is in a horizontal position, so the film (F2) falls flat as shown by the arrow (f), and the belt conveyor type (film transport mechanism) installed in the developing device α1 is used. (b) Fits horizontally on top. This conveyance mechanism (foundation)
An endless belt (c) is stretched between the drive pulley ( ) and the driven pulley (c), and the largest cut film used, such as a half-cut plate (14' x 17"), is placed horizontally in the longitudinal direction. It has a dimension α0 sufficient for , and its width (1
4" has a width slightly wider than 1), and transports the film α2) in the direction of arrow (g) by a motor (not shown). The arcuate guide plate @ is sent out in any posture from the snapshot device opening Qυ. The film α2) is transferred to the transport mechanism (
(e) onto the belt (c). This will be explained in detail when explaining FIG. 5. It goes without saying that the automatic developing device has a closed structure that prevents light from entering. (Foundation) is an automatic developing machine called a so-called continuous conveyance type.It is a device in which various processes such as developing, fixing, washing, and drying are carried out in which the film CH'2) is sequentially fed in the direction of the arrow. There is a reed, roller type, and other conveyance mechanism for each processing solution and cleaning water, but the internal structure is well known and is not shown, but in order to maintain the above-mentioned vertical posture, the processing solution etc. may leak. It performs its function in the same way as a stationary type. The film C after the above-mentioned processing is carried out to the outside through the discharge port. FIG. 6 is a diagram showing the effect of the device (1) according to the present invention, that is, when the bed section (2) is tilted, the automatic developing device α→ maintains a vertical posture. The automatic developing device α suspended from the end (ioz) via a bearing (a) maintains its vertical state as shown in the figure by its own weight. This is true regardless of the position of the X-ray tube support leg Q7) in the longitudinal direction of the bed section (2). The problem here is that the above-mentioned film feeding mechanism (a) of the quick copy device 01 is replaced by the film feeding mechanism (a) in the automatic developing device 0).
In contrast, the bed is tilted at the same angle as the tilt angle (α) of the bed (2).

Figure 4 is a diagram showing an example of a countermeasure against this problem, and is a cross-sectional view of the ■-■ cross section of Figure 2 viewed from the feeding direction of the film C, and the dashed-dotted circle (A) is the above-mentioned feeding mechanism. The attitude of the film α2) when it falls due to the rotation in (a) is shown. -1 is a side guide plate, and a part of the above-mentioned arcuate guide plate (to) is also shown in cross section. With this configuration, for example, when the bed part (2) is in an upright position, the film (F2) falls perpendicular to the upper horizontal plane of the belt (at the next instant C2').
It falls off the side guide plate as shown, and finally σ, +LJ
) on the belt horizontally. Although the film may turn inside out due to the above-mentioned twisting, this does not cause any problem in the developing process.

The above is an embodiment of the present invention, but it goes without saying that the present invention is not limited to the illustrations and descriptions. When the film carriage moves between the standby and photographing positions in the longitudinal direction of the top of the bed, the photographed film is fed from the photographing position to the automatic developing device via the film feeding mechanism. The same effect can be obtained if the quick-shooting device has a structure that is connected to its film advance mechanism, and the automatic developing device is rotatably attached to the quick-shooting device, regardless of its structure. It is fine as long as it is hanging down.

Furthermore, if the snapshot device and the automatic developing device are rotatably engaged, the light-shielding case shown in FIG. 2 is not required if the connecting portion is partitioned off by a wall to form a dark room. In the above embodiment, the self-weight of the automatic developing device is used as a restraining means in the vertical state, but this restraining means is not limited to self-weight; for example, a stopper member may be provided on the snapshot device, or a spring from the floor may Various methods can be considered, such as pulling the

Since the present invention is constructed as described above, it eliminates the drawbacks of conventional X-ray fluoroscopic imaging tables, and allows for the movement of the position of the snapshot device.
The photographed film can be reliably fed to the automatic developing device even when the quick-shooting device is in any position or posture, such as when the bed is up or down, and the time required for diagnosis can be shortened by making photography and developing completely online. This provided a convenient device.
