うな性質を示す蛍光体を蓄積性蛍光体と言う。[Technical background of the invention and its problems 1 Certain types of phosphors contain radiation (XI!it, alpha rays, beta rays,
When irradiated with γ-rays, ultraviolet rays, etc., part of the energy of this radiation is accumulated in the phosphor, and then when the phosphor is irradiated with excitation light such as visible light111, depending on the accumulated energy, , the phosphor exhibits stimulated luminescence. A phosphor exhibiting such properties is called a stimulable phosphor.

性の良い画像を得る方法が提案されている。Using this stimulable phosphor, radiation image information of the human body, etc. is recorded on a sheet of stimulable phosphor, which is scanned with excitation light to cause stimulated luminescence, and this stimulated luminescence is photoelectrically generated. A method has been proposed that reads out an image signal and processes this image signal to obtain an image suitable for diagnosis.

使用することが、経済的である。This final image may be reproduced as a hard copy or on a CRT. In such a radiation image recording and reproducing method, a stimulable phosphor sheet (strictly speaking, it can take various forms such as a panel shape or a drum shape, but it is generally referred to as (hereinafter referred to as "sheet") is economical to use repeatedly.

がある。If sufficient excitation light is irradiated during readout, the accumulated radiation energy caused by the recorded radiographic image information should disappear, but in reality, only excitation light irradiated during readout will Complete deletion is not possible. Therefore, when the phosphor sheet is used repeatedly, there is a problem in that the forward photographed image remains and becomes noise in the next photographed image.

を伝達出来ない等の問題が有った。On the other hand, since the stimulable phosphor contains a small amount of radioactive isotopes such as Ra'P K, the stimulable phosphor sheet will be damaged by radiation from these radioactive isotopes even if left alone. , which accumulates radiant energy, which also causes noise. Energy is also stored by environmental radiation such as cosmic rays and X-rays from other xIla sources. The radiant energy (hereinafter referred to as "fog") that accumulates while the camera is left unused also becomes noise in the next photographed image, so this fog must also be erased before photographing. In addition, in recent years, as radiographic image information recording systems have been established, many images can be taken at once, similar to radiographic film, in order to save labor and shorten diagnosis time from the cassette method. In radiographic diagnosis, the emergence of a cassette-less radiography apparatus for stimulable phosphor sheets has become essential. Furthermore, by arranging the light emitting means within the display device, there is a problem in that the photographed stimulable phosphor sheet is excited and correct image information cannot be transmitted.

is vacuum-adsorbed by the take-out arm 9,
The first one is taken out. When the leading edge of the sheet 3 taken out reaches the light-emitting body 10, the light-emitting body 10 is synchronized to emit light. It receives light irradiation by passing through.The light irradiation energy at this time is
Approximately 100,000 x seconds are required, and the light shielding door 15 is closed until the light irradiation is completed, and the photographed sheet 5 is not affected by the light shielding 1i14. The sheet 3 on which the light irradiation has been completed is transported by the belt 12 along the guide 13 toward the light-shielding door 15 . The path length from the light emitter 10 to the light-shielding door 15 is a large-sized sheet (354an
354 mr) It goes without saying that it is longer. When the leading edge of the sheet 3 that has been irradiated with light is detected by a photoelectric detector (not shown) in front of the light-shielding door, the light-shielding door 15 is activated via a solenoid, etc., and the sheet 3 is placed on standby at the radiographic position by belts 16 and 17. The light shielding door 15 is then transferred to the holding frame 18, which is also detected by a photoelectric detector (not shown), thereby closing the light-shielding door 15. The holding frame 18 is moved to the radiography position to perform radiography, and returns to the radiography position again, and the direction change belt 17a and o-ra 17b of the sheet after radiography have been moved downward. , transported along the storage belt 19 and stored in the pickup magazine.

As a means for taking out the stimulable phosphor sheets 3 one by one from the frontage part 8 of the magazine 2 attached to the side part 6, a vacuum suction type take-out arm 9 was used, but this has the same effect. Needless to say, it may be replaced with any type of product. Furthermore, although the above embodiment relates to a radiographic imaging device for sheets of a single size, even for sheets of different sizes, the pick-up magazine can be configured to allow sheets of different sizes to coexist, and the feed magazine mounting section is It is obvious that the present invention can also be applied to a radiographic rapid photography apparatus for sheets of multiple sizes by providing a plurality of sheets or by having a configuration in which the feed magazine can be removed for each required imaging size.
