Although the conventional cassette-less copying apparatus is constructed as described above, it requires many parts to construct the apparatus, leading to an increase in cost. In particular, there are many parts such as rollers and guides for transporting the film, and a plurality of motors and their control devices are required to drive the rollers, resulting in a large cost allocation for means for transporting the film. Originally, in order to satisfy the functions necessary for a snapshot device, it is sufficient to have a supply magazine, a storage magazine, a holder, and a name printer if necessary, and a means for transporting the film is not necessarily a necessary function. Furthermore, in order to transport the film, the curvature of the guide must be several tens of R from the point of view of reliability, which makes it difficult to arrange the device compactly, and there is also the problem that the device itself becomes large. Additionally, the mechanism is complicated and maintenance is difficult. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems by providing an X-ray cassette-less copying apparatus that can be simplified and reduced in cost by reducing the number of parts.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a supply magazine in which unexposed X-ray films are stacked, and an X-ray film for taking out the X-ray films from the supply magazine.
In a cassette-less snapshot device having a radiation film ejection means, a holder for holding the extracted X-ray film between a pair of plates to which an intensifying screen is attached, and a storage magazine for storing the photographed X-ray film, means for tilting the pair of plates toward the supply magazine when the holder inserts an unexposed X-ray film taken out from the supply magazine into the holder; This is achieved by having one of the means for tilting the pair of plates toward the storage magazine.

[0009]

[Operation] By configuring the snapshot device as described above,
When inserting film into the holder, the holder is tilted towards the supply magazine. Accordingly, when the film is taken out from the supply magazine by the film take-out means, the distance to the holder is shortened, so that the film can be inserted into the holder using the smallest film transport means. Furthermore, when ejecting the film from the holder, the holder tilts toward the storage magazine. As a result, the distance between the holder and the storage magazine is shortened, and the film can be stored in the storage magazine with the minimum amount of film conveyance means, as in the case of inserting the film into the holder. Note that the tilting operation of the holder accompanying the insertion and ejection of the film should be performed for either insertion or ejection, if either the supply or storage magazine can be placed near the holder. Can be done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. 1 is a diagram showing the internal configuration of a snapshot device according to a first embodiment of the present invention, FIG. 2 is a perspective view illustrating a positioning mechanism of the tilting means of the holder, FIG. 3 is a front view of FIG. 2, and FIG. FIG. 2 is a sectional view schematically showing the internal configuration of a snapshot device according to a second embodiment of the invention.

A first embodiment of the present invention will be described below. This first embodiment is suitable when the difference in level between the holder 10 and the supply magazine 7 is large, as shown in FIG. In FIG. 1, a supply magazine 7 and a storage magazine 8 are detachably attached to a case 9, as in FIG. 6. Reference numeral 21 denotes a suction pad, which takes out unphotographed films F from the supply magazine 7 one by one using a known drive mechanism (not shown), moves them in the direction shown by arrow G, and bites them into conveyance rollers 70 and 71. let them get involved.

The holder 10 includes plate members 31 and 32 to which intensifying screens (not shown) are attached, a hinge 49 that rotatably supports these plate members, and a support member 5 that supports the hinge 49.
9, a stopper 57 fixed to the support member 59 and regulating the rotation of the plate members 31 and 32 by the hinge 49, and a force applied in a direction to bring the plate member 32 into close contact with the plate member 31 and to bring both plate members into contact with the stopper 57. a plate spring 58 that gives a
54, a support member 56 that guides these rollers 50, 51, 53, 54 and guides the holder 10 in the X direction, and bearings 39, 40 attached to the support member 56. It is supported by the case 9 by guide members 11a and 11b that guide it in the direction.

Reference numeral 64 is a hook attached to the plate member 32. One end of this hook 64 is in contact with a roller attached to the tip of a lever 60 that is rotatably supported by the case 9.
1 is supported, and a lever 62 is rotatably supported at the other end of this lever 61. A motor 63 is fixed to the other end of this lever 62. As a result, when the motor 63 is rotated by a control device (not shown), the lever 62 rotates, and accordingly, the lever 60, that is, the holder 10, is rotated in the direction indicated by the arrow B via the lever 61.

FIGS. 2 and 3 are a perspective view and a front view illustrating the positioning mechanism when the holder 10 rotates in the direction indicated by arrow B. In FIG. 2, 31 and 32 are the plate members explained in FIG. A part of the side surface of this plate member 31 is bent into an L shape, and a hole 83 is made there. Reference numerals 81 and 82 indicate electromagnetic movable lock pins, and the pins are moved in the directions of arrows Q and R by a control device (not shown). These movable lock pins are attached to a member 80 fixed to the case 9, and determine the stopping position of the holder 10 when it is tilted in the directions shown by arrows B and C.

To explain in detail, when the rotation of the motor 63 is controlled and the holder 10 is moved from position J to position K or L in the directions shown by arrows B and C, lock pins 81 and 82 are inserted into holes 83. A pin is inserted to fix the plate member 31. The position J is the set position when moving from the shooting standby position to the shooting position, the position K is the stop position when inserting the film F into the holder 10, and the position L is the ejection position of the film F from the holder 10. It is. After that, the motor 63
rotates a little further, releases the close contact between the plate members 31 and 32, and facilitates the loading and unloading of the film F. Note that when the holder 10 is tilted with the film F inserted into the holder 10, the holder 10 is controlled to move in the direction indicated by arrow A, that is, the X direction, and to move in the rotating direction. Then, film F, rollers 70, 71 and roller 7
2, 73 to prevent interference.

To summarize the above, first, the motor 63 is controlled to tilt the holder 10 and stop it at the K position. After stopping, the plate member 31 is fixed by the lock pin 81, the motor 63 is further rotated to create a gap between the plate members 31 and 32, and the film F is inserted into the holder 10. Thereafter, the holder 10 retreats in the direction of arrow A, tilts in the direction of arrow D (these may be done at the same time), and returns to the set position. After photographing, the film F in the holder 10 is caught between the rollers 72 and 73 and stopped at the L position by controlling the movement in the direction of the arrow A and the movement in the direction of the arrow B. After stopping, the plate member 31 is fixed with the lock pin 82, and the motor 6 is
3 to release the close contact between the plate members 31 and 32. Then, the film F is stored in the storage magazine 8 by rotating the rollers 72, 73, 75, and 76. After that, the holder 10 retreats in the direction of arrow A, tilts in the direction of arrow C, and
The next unshot film is stored at the K position and the camera returns to the J position. Note that while the film F is being transported, the patient's name, age, etc. are imprinted onto the film F using a name printer. This sequence is continuously shot on film.

Next, a second embodiment will be explained using FIG. 4. The second embodiment shown in FIG. 4 is different from the first embodiment in that the mounting position of the supply magazine 7 is brought closer to the set position of the holder 10 (reducing the level difference), and the film F is placed in the holder 10 at the set position. The other difference is that the suction pad is directly inserted into the rollers 90 and 91, but the other features are the same. In this way, if the position of the supply magazine 7 can be brought closer to the set position of the holder 10, the number of stopping positions for tilting the holder 10 will be reduced, making it possible to simplify the arrangement. Note that even if the positional relationship between the supply magazine and the storage magazine is reversed in this second embodiment, the number of stopping positions of the holder 10 will be reduced, making it possible to simplify the structure.

As described above, according to the embodiment of the present invention, a means for tilting the holder 10 is newly added, but the number of rollers and guides for conveyance can be significantly reduced compared to the conventional method. This makes it possible to reduce the overall number of parts, thereby lowering costs. Furthermore, Figure 7
Since there is no need for a path to reverse the film as shown in the example shown in Figure 2, the supply magazine and the storage magazine are moved upwards, so the vertical dimension can be suppressed and the device can be made compact. Since the transport distance of the film F is shortened, it can be expected that transport troubles will be reduced and maintenance will become easier.
