Abstract
Abstract A radiation image read-out and reproducing apparatus comprises a section for feeding a stimulable phosphor sheet carrying a radiation image stored thereon, a section for feeding a recording sheet, a section for photoelectrically reading ID information, and a light beam scanning section. The light beam scanning section comprises a read-out main scanning system for scanning a light beam in a main scanning direction on the stimulable phosphor sheet, a reproducing main scanning system for scanning a light beam in a main scanning direction on the recording sheet, and a sub-scanning system for moving the stimulable phosphor sheet and the recording sheet in a sub-scanning direction, thereby to read out a radiation image from a stimulable phosphor sheet and to reproduce a radiation image and ID information on a recording sheet by modulating the light beam in the reproducing main scanning system in accordance with a radiation image read out and information detected by the ID information reading section.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
385 words
A radiation image read-out and reproducing apparatus comprising: (i) a stimulable phosphor sheet feeding section for housing a stimulable phosphor sheet carrying a radiation image stored theron, and feeding out said housed stimulable phosphor sheet, (ii) a recording sheet feeding section for housing recording sheets and feeding out said housed recording sheets one by one, (iii) an information reading section for holding an information recording means, which carries photoelectrically readable information different from said radiation image and represented by characters, or the like, and provided with an information reading means for photoelectrically reading said information, (iv) a light beam scanning section provided with a read-out main scanning means for deflecting a light beam with a light deflector and scanning said light beam in a main scannning direction across a stimulable phosphor sheet, a reproducing main scanning means for deflecting a light beam with a light deflector and scanning said light beam in the main scanning direction across a recording sheet, and a sub-scanning means for causing said stimulable phosphor sheet and said recording sheet, respectively, to be scanned in a sub-scanning direction by moving the sheets in a direction approximately perpendicular to said main scanning direction, wherein read-out of a radiation image is carried out by causing a stimulable phosphor sheet to emit light carrying information about said radiation image when exposed to the light beam in said read-out main scanning means and detecting the emitted light by use of a light detection means, and a radiation image thus read out and information detected by said information reading means are reproduced together on a recording sheet by modulating the light beam in said reproducing main scanning means in accordance with said radiation image thus read out and said information detected by said information reading means, (v) a stimulable phosphor sheet conveyance means for receiving a stimulable phosphor sheet fed out of said stimulable phosphor sheet feeding section, conveying said stimulable phosphor sheet to said light beam scanning section, and thereafter conveying said stimulable phosphor sheet out of said light beam scanning section, and (vi) a recording sheet conveyance means for receiving a recording sheet fed out of said recording sheet feeding section, conveying said recording sheet to said light beam scanning section, and thereafter conveying said recording sheet out of said light beam scanning section.
Claim 2
Dependent Claim
385 words
A radiation image read-out and reproducing apparatus comprising: (i) a stimulable phosphor sheet feeding section for housing a stimulable phosphor sheet carrying a radiation image stored theron, and feeding out said housed stimulable phosphor sheet, (ii) a recording sheet feeding section for housing recording sheets and feeding out said housed recording sheets one by one, (iii) an information reading section for holding an information recording means, which carries photoelectrically readable information different from said radiation image and represented by characters, or the like, and provided with an information reading means for photoelectrically reading said information, (iv) a light beam scanning section provided with a read-out main scanning means for deflecting a light beam with a light deflector and scanning said light beam in a main scannning direction across a stimulable phosphor sheet, a reproducing main scanning means for deflecting a light beam with a light deflector and scanning said light beam in the main scanning direction across a recording sheet, and a sub-scanning means for causing said stimulable phosphor sheet and said recording sheet, respectively, to be scanned in a sub-scanning direction by moving the sheets in a direction approximately perpendicular to said main scanning direction, wherein read-out of a radiation image is carried out by causing a stimulable phosphor sheet to emit light carrying information about said radiation image when exposed to the light beam in said read-out main scanning means and detecting the emitted light by use of a light detection means, and a radiation image thus read out and information detected by said information reading means are reproduced together on a recording sheet by modulating the light beam in said reproducing main scanning means in accordance with said radiation image thus read out and said information detected by said information reading means, (v) a stimulable phosphor sheet conveyance means for receiving a stimulable phosphor sheet fed out of said stimulable phosphor sheet feeding section, conveying said stimulable phosphor sheet to said light beam scanning section, and thereafter conveying said stimulable phosphor sheet out of said light beam scanning section, and (vi) a recording sheet conveyance means for receiving a recording sheet fed out of said recording sheet feeding section, conveying said recording sheet to said light beam scanning section, and thereafter conveying said recording sheet out of said light beam scanning section.
Claim 3
Dependent Claim
