摘要： In an image read-out method, image signals are obtained by scanning a material-to-be-scanned, which carries an image recording thereon and which is conveyed in a sub-scanning direction, by a light beam deflected by a rotating polygon mirror in a main scanning direction approximately normal to the sub-scanning direction, and photoelectrically detecting light, which carries the image and which is obtained from a portion scanned by the light beam, by a photodetector. The image signals each obtained in each of main scanning steps in a number obtained by a single turn of the rotating polygon mirror or turns thereof in a number equal to integral multiples of one are addition-processed to obtain an image signal over a single main scanning line.

摘要： A radiation image read-out and reproducing apparatus wherein radiation image read-out and reproduction are carried by use of the same scanning system in the same apparatus. The light beam scanning section includes a read-out main scanning means and a reproducing main scanning means. The light source as well as the light deflector of the read-out main scanning means are the same as the light source and light deflector of the reproducing main scanning means. Further, the means for conveying the stimulable phosphor sheet for read-out and for conveying the recording sheet for reproducing are common to each other. A beam diameter adjusting means adjusts the beam diameter of the light beam between a position on the stimulable phosphor sheet and a position on the recording sheet by moving the beam diameter adjusting means into or away from an optical path of the light beam depending upon whether the light beam scans the stimulable phosphor sheet or the recorded sheet. Also included is an automatic developing machine for carrying out development on the recording sheet carrying the radiation image reproduced thereon.

摘要： An image read-out and reproducing apparatus comprises an acousto-optic modulator, and a change-over device for guiding zero-order light and first-order light radiated by the acousto-optic modulator to a predetermined optical path. A deflector deflects a light beam to scan an image-recorded image information sheet or a recording sheet in a main scanning direction, and a sub-scanning device moves the image information sheet or the recording sheet normal to the main scanning direction. When the image information sheet is moved by the sub-scanning device, zero-order light is guided by the change-over device to the predetermined optical path and deflected to scan the image information sheet, thereby to carry out image read-out from the image information sheet. When the recording sheet is moved by the sub-scanning device, first-order light is guided by the change-over device to the predetermined optical path, modulated in accordance with image signals and deflected to scan the recording sheet, thereby to reproduce the image on the recording sheet.
