Abstract

PURPOSE:To make it possible to allow the title apparatus to correspond to a recording medium in each of various photographing directions, by detecting the photographing direction of a radiation recording medium and converting the same to a predetermined direction on the basis of the detection output. CONSTITUTION:When the radiation image converting panel (IP)2 in the take-up magazine 4a mounted to an insert port A receives the input of a signal for selecting the magazine 4a, a radiation recording medium is taken out onto the IP panel 15 one at a time by a suction cup 5. After the outtake is completed, the suction cup 5 returns to the initial position and the IP tray 15 is rotated by 90 deg. to right by a rotary driving motor 17 and stopped by a limit switch. Subsequently, a IP guide panel 9 advances through a rack 20 and a pinion 21 to push the rear end of IP2 which is, in turn, subjected to positional determination straightly at the contact part of a roller pair 6. IP2 is detected by a photoelectric detector S and the feed rollers 6 and a belt 7 are driven by the detection signal thereof to be fed to a reading part. Because IP subject images in different directions stored in magazines 4a, 4b, 4c are also fed to the reading part in a difinite direction, the correspondence to many kinds of take-up magazines is enabled.

are attached to the MAFl, taken out one by one by the suction cup 5, and conveyed to the image reading section 8 via the conveyance roller 6 and belt 7 by a drive system (not shown). In the image reading section 8,
Laser light 10 transmitted from laser tube 9 passes through lens 1
1. The image information is converted into light by scanning the IPa via the vibrating mirror 12, and converted into an electrical signal by the photomultiply A7-14 via the light guide 13. The converted electrical signal is sent to the A/ The signal is D-converted and input to the image processing control section, and further D/A converted by the image recording section, and image information is recorded on the CR film while controlling the laser beam using this input signal.

In recent years, as the OR system diagnostic method has been established, the cassette method, similar to the X-ray film, has made it possible to evaluate multiple sheets at once to save labor and shorten the diagnosis time. The emergence of an xm snapshot device exclusively for SPs has become desirable.

Furthermore, in sheet film X-ray speed photography devices, the direction of the object and the direction of the object image in the pickup magazine vary widely depending on the device, as shown in FIGS. 2 to 5.

That is, in the case of the nozzleless X-ray copying apparatus 30 shown in FIG.
It is stored in the state shown in Fig. 2<b). In addition, in the case of the Karetsuteres X-ray rapid imaging system @30 shown in FIG. 3(a), the device in FIG.
is stored in the opposite direction. Furthermore, as shown in FIGS. 4 and 5, the subject PAP observed on the film 31 stored in the pickup magazines 4b and 4C by the X-ray copying apparatus 34 and 35 having different configurations cannot be turned upside down. However, the shooting directions are different.

[Problems with the background technology] However, unlike the conventional film method, in the OR system diagnostic method, when recording the image information of the photographed [P] on a CR film or displaying it on a CRT display, the output image is Since it is desired that the image be in a constant direction, an IP transport system is provided so that the direction of the IP stored in the take-up magazine and the direction of the subject image are stored in a constant direction regardless of the X-ray speed copying device. , it was necessary to contribute to shortening and simplifying the image processing time in the OR system.

Therefore, the IP transport direction from the MAF to the image reading unit is limited as shown in Figure 6, which makes the IP transport system of the cassetteless X-ray copying device complicated, making the device larger and heavier. Since compatibility with the IP transport method and the pick-up magazine is limited to one type, other cassettes
There was a problem that it lacked versatility and application to line speedgraphs.

[Object of the invention] The present invention eliminates the above drawbacks and provides a simple IPwi
It is an object of the present invention to provide a recording medium conveying device that is capable of handling recording media in various photographing directions by providing a horizontal conveyor 1a.

[Summary of the Invention] In order to achieve this object, the present invention accumulates a plurality of radiographic image recording media each having a different patient exposure direction, each of which has been line-imaged by radiographic apparatuses in different imaging conditions, and A recording medium conveyance device that sequentially conveys image information recorded on a recording medium to an image reading section that reads the image information includes a detection means for detecting the photographing direction of the radiation image recording medium, and a detection means for detecting the imaging direction of the radiation image recording medium, and a detection means for detecting the radiographic image based on the output of the detection means. The apparatus is characterized in that it includes a changing means for changing the conveyance direction of the recording medium, and changes the imaging direction of the radiographic image recording medium to a predetermined value.

[Embodiment 1 of the Invention Figure 7.8 shows a principle embodiment of the IP transport system in the MAF of the present invention.

In the diagram, △ and B are tick-up magazine insertion slots, 2.3
is X a Vn shadowed rP, 4a, 4b, 4c are 2nd ~
As shown in Figure 5, there is a tray containing the IP of the subject image, a pick-up magazine, 5.5 is the suction cup, 6.7 is the roller and belt for transporting the IP, 15 is the IP to which the gear 16 is fixed.
The I-ray 17 is a drive motor for rotating the IP upper tray 5 left and right, and gears 17-18 are fixed to the tip thereof. 19 is an IP guide plate to which the rack 20 is fixed;
21 is a pinion that reciprocates the IP guide plate 19 back and forth by a motor (not shown). In addition, reed switches are installed in insertion slots A and B for pickup magazines 4a14b and 4C.
A magnet is attached to each, making it possible to recognize which tick-up magazine is attached, and
The left and right rotation motor 17 of the I-ray 15 is controlled by mounting signals from the pickup magazines 4a and 4b.

Further, a tick-up magazine 4a or 4b can be attached to the insertion opening A of the MAF, and a tick-up magazine 40 can be attached to the insertion opening B of the MAF.

The operation of the present invention will be explained using FIG. When the magazine 4a selection signal is input, the IP2s in the pick-up magazine 4a loaded into the insertion slot are taken out one by one onto the IP upper tray 5 by the suction cup 5. After the removal is completed, the suction cup 5 returns to the initial position, and the IP upper tray 5 is rotated 90 degrees to the right by the rotary drive Tanabata 17 and stopped by a limit switch (not shown).

After that, one IP guide plate behind the IPt-ray 15 is attached to the rack 20. Proceed through the pinion 21 and move forward from IP1 to Ray 1.
Push the rear end of IP2 on 5 and position IP2 straight at the contact part of the pair of conveying rollers 6.

At this time, it is obvious that reliable conveyance without slippage is required by appropriately selecting the roller material, pressure, etc.

The positioned IP2 is detected by a photoelectric detector S provided on the W1 transport roller 6, and the transport roller 6 and belt 7 are driven by the detection signal and transported to the reading section.

When the pickup magazine 4b is inserted, the IPI-ray 15 is similarly rotated 90 degrees to the left by the magazine 4b selection signal, and is transported to the reading section in the same manner as described above.

, Also, the tick-up magazine 4C installed in the insertion slot B
In response to the selection signal of the magazine 4C, the IP3 is taken out one by one by a separately driven suction cup 5-, transferred to the conveyance belt 7, and conveyed to the reading section.

Therefore, as shown in the flow of IP within the MAF in Fig. 9, the IP subject images stored in the pick-up magazines 4a, 4b, and 4G in different directions are also conveyed to the reading section in a fixed direction by the above-mentioned conveyance. , compatible with many types of take-up magazines.

Although the above explanation is about a single size IP, 2,
It goes without saying that it is possible to apply the above technology to a tick-up magazine containing three types of IPs of different sizes.

FIG. 10 shows another embodiment, and FIG. 11 is a side view thereof. C in the figure is a tick-up magazine insertion opening, and the tick-up magazine 4a can be inserted by interposing an adapter (not shown) or the like.

Both 4b and 4C can be installed. 5 is a suction cup, 22 is a conveyance diagonal belt, 23 is a guide belt, 24
2 is a reference guide plate, and 25 is an eccentric pulley.

The guide belt 23 is P in the case of a large size IP.
The structure is such that it rotates in the direction of arrow Q around a point to widen the width of the IP passage.

The terminal pulley 25 of the upper oblique belt 22 rotates eccentrically, and the gap between the upper and lower oblique belts varies in the range of 0.4 to 2 m11, so the comparison is made within the gap of the oblique belt i-. Appropriate conveying force can be obtained by freely adjusting the IP force direction.

Further, in the guide bells 1 to 23, as in the previous embodiment, the pick-up magazine and the insertion slot C are rotated in the arrow direction or [direction] by a magnetic sensor.

The operation of this embodiment will be explained using FIGS. 12, 13, and 14.

When the pick-up magazine 4a is installed, the IP contacts the guide belt 23 rotating in the D direction, and the skew belt 2
2 and is rotated and transferred to the reference guide plate 24 side. (Fig. 12) When the pick-up magazine 4b is installed, the IP contacts the guide belt 23 which reverses in the E direction, is changed direction by the vibration force of the IP, and is transferred to the reference guide plate 24 side. . (FIG. 13) When the pick-up magazine 4C is installed, the guide belt 23 rotates in the same direction as in FIG. 12.

At this time, the IP
is transported in the direction in which it was taken out by the suction cup, with almost no effect of the guide belt 23. (FIG. 14) Therefore, as in the previous embodiment, the pick-up magazine 4a,
Object images P stored in 4b and 4c in different directions can also be conveyed to the reading section in a fixed direction.

[Effects of the Invention] As described above, the recording medium conveying device of the present invention not only shortens the processing time and simplifies the processing technology for correcting the output image direction in the image processing unit, but also enables IP exclusive use. There is no need to provide a transport system for correcting the IP force direction within the cassette telegraph X-ray imaging device, and conventional technology can be followed.
The dedicated cassette-less X-ray photographic device is small, lightweight, and simple, and can be easily adapted to many types of devices.
