Abstract

PURPOSE:To prevent an IP from being damaged and also to reduce a driving load by providing a guide member guiding a recording sheet IP to the aperture of a containing magazine of a spot shorting device and a flexible member brought into contact with this guide member. CONSTITUTION:When a photographed IP 11 is sent to the upper part of an opening part 65a of a storing magazine 65 by a feeding mechanism art 63, a retaining plate 66 is pushed downward by the action of a pressing mechanism part 67, therefore, it works so as to push the IP 11 into the aperture 65a. In such a case, when the IP 11 guided by a guide member 71 and pushed downward is brought into contact with a flexible member 72, this flexible member 72 is bent easily, therefore, the IP 11 is further pushed in by the retaining plate 66, by which it is stored and laminated in the storing magazine 65 from the aperture 65a. In such a way, the damage of a recording sheet is prevented and also a driving load is reduced.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides an X-ray system that uses a stimulable phosphor sheet to create a pupil image transmitted by X-rays irradiated toward a subject for diagnosis. The present invention relates to radiation diagnostic equipment.

(Conventional technology) Certain types of phosphors are exposed to radiation (X-rays, α-rays, β-rays.

When irradiated with T-rays, ultraviolet rays, etc., some of this radiation energy is accumulated in the phosphor, and when the phosphor is then irradiated with excitation light such as visible light, the phosphor changes depending on the accumulated energy. Shows stimulated photoluminescence. A phosphor exhibiting such properties is called a stimulable phosphor.

Using this stimulable phosphor, radiation image information transmitted through the human body, etc. is recorded on a sheet of stimulable phosphor (hereinafter referred to as an imaging plate = IP), and this IP is scanned with excitation light to be stimulated. A method has been proposed in which an image is obtained by emitting light and reading out the stimulated luminescence photoelectrically. This I
P has the property of being able to be reused again and again after the recorded image is read out by performing readout irradiation for photostimulation after the radiation exposure, and is used in X-ray diagnostic equipment as a highly economical product. It is used.

When the IP'11 is pushed into the opening 65a of the storage magazine 65 by the holding plate 66, the flexible member 72
The IPll guided by the guide member 71 and the presser plate 66 move to bend downward about the point P as a fulcrum, as shown in FIG. The length of the flexible member 72 from the point P toward the inside of the accommodation magazine 65 is such that the end 72a does not come into contact with the stacked IPlls accommodated in the accommodation magazine 65, and the end 72a extends inward from the accommodation magazine 65. It is selected such that it can sufficiently reach the inside of the side plate 65G of 65. When the flexible member 72 is roughly bent upward, it should be bent to the extent that it does not contact the presser plate 66 which has returned to its normal upper position (the position shown in FIG. 2) after the pushing operation of the IPll is completed. The length L is chosen. The storage magazine 65 is attached to the magazine side plate 74a.
, 74b.

Next, the operation of this embodiment will be explained.

When the I-shaded IPll is fed into the upper part of the opening 65a of the storage magazine 65 by the feeding mechanism 63 in FIG. It acts like pushing towards.

At this time, when the IPll guided and pushed downward by the guide member 71 comes into contact with the flexible member 72, the flexible member 72 is easily bent, so that the IPll is pushed against the presser plate 66.
By roughly pushing them in, they are accommodated in the accommodation magazine 65 through the opening 65a and stacked. When the pressing operation of the presser plate 66 is completed, the pressing mechanism section 67 shown in FIG. 2 stops working (returns to the upper position).
Therefore, the presser plate 66 returns to its normal height position due to the biasing force of the spring 68 provided in advance.

At this time, the flexible member 72 is bent in a direction away from the storage magazine 65 by the presser plate 66, and then returns to the normal height position shown in FIG. 3 to be ready for the next IP storage operation.

According to the apparatus of this embodiment, even if the apparatus is tilted up and down over the range of 90' to -90 degrees for photographing purposes, the image-transferred IPll remains pushed into the guide member 71 while being pushed into the holding plate 66. After being guided by, the flexible member 72 is bent and accommodated in the accommodation magazine 65, so that it is accommodated smoothly. However, when the flexible member 72 is bent to the maximum, its position moves to the position 72' in FIG. 4, so that a flat surface continuous with the surface of the guide member 71 is formed. Since no step part is formed, IPII
The edges of the can be smoothly accommodated without damage. Furthermore, even if the IP is relatively heavy and rigid, the flexible member 72 is easily bent during storage, so the driving load on the holding plate 66 that presses the IPll can be extremely reduced. Therefore, the degree of freedom in device design can be improved, and the structure can be simplified.

[Effects of the Invention] As described above, according to the present invention, damage to the IP can be prevented because a guide member for guiding the IP and a flexible member in contact with the guide member are provided in the opening of the storage magazine. At the same time, the driving load can be reduced.
