As shown in FIG. 2, the medical bed 10 is provided with a mounting portion 12 into which the cassette holder 1 is inserted below the bed portion 11 where the patient lies. FIG. 5 is a view showing the mounting portion 12 by raising the bed portion 11 toward the bed frame 10. As shown in FIG. 5, the mounting portion 12 is provided with a guide rail 15 extending in parallel in the insertion direction 6 of the cartridge holder 1. The guide rail 15 has an L-shaped cross-sectional shape and is fixed to the bed frame 10, and a pair is disposed on both sides of the bed.

As shown in Fig. 1, the cassette holder 1 is formed such that the holder body 2 is provided with vertical wall surfaces 2a, 2b, 2c, and 2d on the four sides of the rectangular bottom plate, and the sheet cassette can be fitted and received in the holder. A space surrounded by the vertical wall surfaces 2a, 2b, 2c, and 2d. A detachable outer casing 3 is provided at one end portion (rear end portion of the insertion direction 6) in the longitudinal direction of the sheet retaining seat 1, and a fixing means such as a rod and a connecting rod to be described later is provided in the outer casing 3. . One side surface of the outer casing 3 serves as a side 2a of the fitting piece.

In the two sides of the shoe body 2 of the film holder 1 which are parallel to the insertion direction 6, a central mark 4 for confirming the position of the film holder 1 at the bed is provided. Further, two rollers 5 are provided on the two sides of the socket body 2 parallel to the insertion direction 6, and the rollers 5 are arranged to be rotatable about a rotation axis perpendicular to the insertion direction 6. The roller 5 is formed to be rotated on the bottom surface of the L-shape while being guided by the L-shaped façade of the guide rail 15. As a result, the roller 5 of the cassette holder 1 is guided by the guide rail 15 and is rotated by the guide rail 15 so as to be movable along the guide rail 15 in the insertion direction 6.

As shown in Fig. 1, in the rear end portion of the insertion pocket 6 in the insertion direction 6, the socket fixing means of this embodiment is provided in the region where the outer casing 3 is disposed. In other words, at both end portions in the lateral direction of the socket main body 2 (both end portions perpendicular to the insertion direction 6), the fixing rods 21, 31 and the rotation are arranged to protrude outward from the socket main body 2, respectively. Rods 22, 32 and stops 24, 34. As shown in FIGS. 3 and 4, the fixing bars 21, 31 are fixed to the socket body 2 with their longitudinal directions perpendicular to the insertion direction 6. The rotary levers 22, 32 are rotatably supported by the rotary shafts 23, 33, respectively, which are disposed perpendicular to the socket body 2 in the axial direction thereof. The stoppers 24, 34 are similarly rotatably supported by the rotary shafts 23, 33, respectively, and the rotary levers 22, 32 and the stoppers 24, 34 are respectively fixed to be fixed to each other, and have an integral configuration. Therefore, the rotating levers 22, 32 and the stoppers 24, 34 are rotated about the same direction while centering on the rotating shafts 23, 33. Contact portions 25, 35 are provided at the front ends of the respective stoppers 24, 34. When the stoppers 24, 34 are rotated toward the outside, the contact portions 25, 35 are in contact with the guide rail 15, by the contact portions 25, 35 and the guide rails. 15 The frictional force of the sheet holder 1 can be locked to the guide rail 15. The surfaces of the contact portions 25, 35 are covered with a rubber-based material to improve the frictional force with the guide rail 15. By doing so, the locking force between the cassette holder 1 and the guide rail 15 can be increased, that is, the braking force can be increased.

As shown in FIG. 6, the rotating shaft 23 of the rotating lever 22 on one side rotatably supports the connecting piece 26 in addition to the rotating lever 22 and the stopper 24, and the connecting piece 26 is coupled to the rotating lever 22 And the stoppers 24 are fixed integrally, and are simultaneously rotated in the same direction. Further, a coupling piece 36 is also fixed at the center of the stopper 34 on the other side. Between the front end portion of the connecting piece 36 and the end portion of the connecting piece 26 separated from the rotating shaft 23, the connecting rod 41 rotatably connects the connecting pieces 26 and 36. By doing so, the stopper 24 and the stopper 34 can be rotated in conjunction. That is, when the stopper 24 is rotated toward the direction in which the contact portion 25 contacts the guide rail 15, the stopper 34 is also rotated toward the direction in which the contact portion 35 contacts the guide rail 15, and when the stopper member 24 is in contact with it. When the portion 25 is rotated in the direction in which the guide rails 15 are separated, the stopper 34 also rotates toward the direction in which the contact portions 35 are separated from the guide rails 15.

Further, as shown in FIGS. 3, 4, and 6, the compression spring 27 is urged in a direction in which the stopper 24 is pressed toward the guide rail 15. As a result, the contact portions 25, 35 of the stoppers 24, 34 are often in contact with the guide rails 15.

Next, the operation of the cartridge holder and the medical bed of the present embodiment configured as described above will be described. First, as shown in FIG. 2, the cassette holder 1 in which the unused sheet bundle is accommodated is inserted into the lower portion of the bed portion 11 of the bed 10. Inside the loading section 12. At this time, as shown in Fig. 5, the roller 5 of the cassette holder 1 is guided to the elevation of the L-shaped cross section of the guide rail 15, and is rotated on the horizontal portion of the bottom surface. In this manner, the cassette holder 1 is guided by the guide rail 15 until it is inserted into the mounting portion 12 below the bed portion 11. When the sheet holder 1 is inserted, the operator moves the sheet holder 1 while holding the fixing rod 21 and the rotating rod 22. As a result, by holding the fixing rod 21 and the rotating rod 22, that is, as shown in FIG. 3, the contact portion 25 of the stopper 24 becomes separated from the guide rail 15. Further, as long as the fixing rod 21 and the rotating rod 22 disposed on one side of the cassette holder 1 are held, the fixing rod 31 and the rotating rod 32 disposed on the other side of the cassette holder 1 are also transmitted through the connecting rod 41. At the same time, the contact portion 35 of the stopper 34 is also separated from the guide rail 15. As a result, when the cassette holder 1 is moved, the fixing rod 21 and the rotating rod 22 are held first, and the contact portions 25, 35 of the stoppers 24, 34 are separated from the guide rail 15. Further, it is of course also possible to hold the fixing rod 21 and the rotating rod 32 instead of holding the fixing rod 21 and the rotating rod 22.

When the cassette holder 1 is inserted into a predetermined mounting position, the fixing rod 21 and the rotating rod 22 are released. In this way, as shown in FIG. 4, by the elastic force of the compression spring 27, the stopper 24 is rotated in the direction in which the contact portion 25 contacts the guide rail 15, and the connecting rod 41 is used, and the stopper on the other side is used. 34 also rotates in a direction in which its contact portion 35 comes into contact with the guide rail 15. By doing so, the contact portions 25, 35 of the stoppers 24, 34 are in contact with the guide rail 15, and the contact portions 25, 35 are pressed against the guide rail 15 by the compression spring 27, so that the friction between the contact portions 25, 35 and the guide rail 15 is utilized. The force generates a braking force in the cassette holder 1 and stops at a predetermined mounting position. So whether it is bed movement Or vibration, the position of the cassette holder 1 does not change. Further, even if the bed portion of the bed is rotated by the extension operation of the bed, the foot side is upward, or the head side is upward, and the cassette holder 1 does not move.

By arranging the guide rail 15 in advance over the entire length of the bed portion 11 of the bed, the cassette holder 1 can be attached to any position of the bed portion 11, and X-ray photography can be performed on the entire body of the patient.

Further, in the above-described embodiment, the rod, the stopper, and the like are provided at the rear end portion of the stack holder 1, but the positions of these members may be arbitrarily set in the cassette holder 1 depending on the condition of the bed structure or the like. Any location.
