Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cassette holding mechanism of the cassette tray of the X-ray imaging table image receiving unit.

[0002]

[Prior art]

 FIG. 1 shows a stand-up X-ray imaging stand. Reference numeral 1 is a pillar, 2 is a guide rail provided on both side walls of the pillar, and 3 is an X-ray image receiving unit that moves up and down along the guide rail 2. 2 and 3 show a conventional cassette holding mechanism of a cassette tray. 2 and 3 show a state in which the cassette tray unit 4 is pulled out from the image receiving unit 3, and FIG. 2 shows a cassette holding mechanism of the cassette tray unit, and 5 and 6 show the cassette lower portion in the center of the cassette tray according to the cassette size. This is a hole for mounting the cassette support 7, which is provided in multiple stages according to the size of the cassette. Reference numerals 8 and 9 are holding plates for pressing the cassette 10 from both sides as shown in FIG. 3 so that the cassette 10 placed on the cassette support 7 is arranged at the center position of the cassette tray. Reference numeral 11 is a tightening lever for fixing the cassette 10 placed at the center of the cassette tray. Since the conventional cassette is mounted on the cassette tray with the structure described above, the cassette support can be repositioned so that cassettes of different cassette sizes can be accurately placed at the center position of the cassette tray. In addition, moving the holding plates on both sides of the cassette and tightening the tightening lever are complicated, and there is a drawback that the cassette may be dropped from the cassette tray during the operation.

[0003]

[Problems to be solved by the device]

 The present invention is to ensure that cassettes of different sizes can be securely held at the center position of the cassette tray of the X-ray imaging image receiving unit and that the operation can be performed easily and in a short time.

[0004]

[Means for Solving the Problems] A cassette tray in the image receiving unit is equipped with a slide board having a vertical guide groove, and a cassette receiver, a cassette guide plate having a cassette size corresponding hole, and a cassette receiver are provided on the slide board. A slide metal fitting and a leaf spring with a protrusion for moving and fixing to the cassette size corresponding hole of the cassette guide plate are installed, and two tension springs are stretched between the slide board and the cassette guide plate. Place the cassette on the cassette holder, and while pushing it downward, make sure that the cassette is fixedly ejected to the cassette tray by the force of the tension spring.

【Example】

 4 and 5 show an embodiment of the cassette holding mechanism of the present invention mounted on the cassette tray 12 in the image receiving section. FIG. 4 is a front view and FIG. 5 is a side view. In FIG. 4, a left half portion from the center line ab shows a cassette guide plate portion 17 which cuts a part 14 of the slide substrate 13 and has cassette size corresponding holes 15 and 16. FIG. 5 shows a cassette holder 19 with a push button 18 installed on the slide board 13, a cassette guide plate 17, and a slide metal fitting 20 for moving and fixing the cassette guide 19 to a position corresponding to the cassette size corresponding to the cassette guide plate 17. The side view of the leaf spring 21 with a protrusion is shown. In FIG. 4, reference numerals 22 and 23 denote two tension springs stretched between the slide substrate 13 and the cassette guide plate 17. Reference numeral 24 is a vertical guide groove formed along the center line of the cassette substrate 13. The cassette guide plate 17 is guided by this groove and can move up and down. The slide metal fitting 20 and the cassette holder 19 are connected via the shaft of the push button 18, and the shaft of this push button is fitted into the guide groove 24 of the cassette substrate 13 and the vertical guide groove 25 of the cassette guide plate 17. Therefore, the slide metal fitting 20 and the cassette holder 19 can be moved up and down along both grooves.

[0006]

[Explanation of device operation]

 Since the cassette holding mechanism according to the present invention is configured as described above, in order to install the cassette on the cassette tray, first pull out the cassette tray from the image receiving section and set the cassette receiver 19 according to the size of the cassette to be installed. In order to adjust the position, push the push button 18 provided on the cassette receiver to push out the protrusion of the leaf spring of the slide metal fitting 20 from the cassette size corresponding hole of the cassette guide plate 17 currently inserted, as shown in FIG. If the slide bracket 20 and the cassette holder 19 connected thereto are moved to the positions of the desired cassette size corresponding holes 15 and 16 of the cassette guide plate 17 and the pushing force of the cassette holder push button is returned, The protrusion of the leaf spring of the metal fitting is inserted into the hole corresponding to the desired cassette size of the cassette guide plate to receive the cassette receiver. To be fixed to the plate. In this way, the cassette receiver is positioned, the cassette 26 is placed on the cassette receiver 19 with its center aligned as shown in FIG. 7, and the cassette upper part is provided on the cassette tray while pushing downward. The cassette is fixed by the retaining metal fittings, and the tension of the two tension springs 22 and 23 stretched between the cassette guide plate 17 and the slide substrate 13 fixes the cassette.

[0007]

[Effect of device]

 The cassette holding mechanism of the present invention pulls out the cassette tray part from the image receiving part, pushes the push button of the cassette receiver and slides the cassette receiver to position the cassette receiver according to the size of the cassette, and then to position the cassette receiver. Since the cassette can be placed with its center aligned and fixed by the force of the spring while pushing it downwards, its operation is simpler and more reliable than the conventional cassette mounting method. In addition, when a cassette with a different cassette size is attached, the tension spring is stretched between the slide base plate and the cassette guide plate, so even if the position of the cassette receiver on the cassette guide plate is different. Since the force of the spring applied to the cassette does not change, fatigue of the spring due to the size change of the cassette is prevented and the spring life is extended. Also it has an averaging effect of the force during the cassette mounting.
