Claims
- 1. An adjustable radiation image recording and read-out apparatus comprising:
- (i) a plurality of independently controlled circulation and conveyance means for conveying at least one stimulable phosphor sheet (2) for recording a radiation image thereon along a predetermined circulation path, each of said circulation and conveyance means including means for frictionally supporting said sheet in vertical and horizontal positions to facilitate the transfer of said sheet from one of said plurality of circulation and conveyance means to another one of said circulation and conveyance means;
- (ii) an image recording means (5) having radiation source means, and object support member, at least one of said independently controlled circulation and conveyance means positioned in said circulation path for temporarily holding a sheet in alignment with said source and object support member for recording a radiation transmission image of an object on said stimulable phosphor sheet by directing radiation through said object to said sheet, and transfer means (9) for moving said at least one circulation and conveyance means toward and away from said object support member for adjusting the distance between said object support member and said at least one circulation and conveyance means and returning said at least one circulation and conveyance means to said circulation path;
- (iii) an image read-out means (6) having at least another of said independently controlled circulation and conveyance means positioned on said circulation path and consisting of a stimulating ray source (62) for emitting stimulating rays for scanning said stimulable phosphor sheet carrying said radiation image stored thereon in said image recording means, and a photoelectric read-out device (63) for detecting light emitted from said stimulable phosphor sheet scanned with said stimulating rays to obtain an electric image signal; and
- (iv) an erasing means (7) having at least another of said independently controlled circulation and conveyance means for, prior to the next image recording on said stimulable phosphor sheet for which the image read-out has been conducted in said image read-out section, having said stimulable phosphor sheet release the radiation energy remaining on said stimulable phosphor sheet.
- 2. An apparatus as defined in claim 1 wherein said transfer means comprises a pair of upper and lower externally threaded screws (91) enclosed horizontally within a lead case (53); a pair of internally threaded members (92) threaded on said screws respectively and supporting said at least one circulation and conveyance means therebetween, and a pair of motors (93) for rotating the screws, wherein the rotation of screws (91) adjusts the position of said at least one circulation and conveyance means with respect to the object support member (51).
- 3. An apparatus as defined in claim 1 wherein said at least one circulation and conveyance means comprises a belt conveyor (52a) and retaining rollers (52b) for pressing the phosphor sheet onto the belt conveyor.
