摘要： A laser beam of a constant intensity is generated by a semiconductor laser and applied to a thermosensitive recording medium. The density of a colored recorded area of the thermosensitive recording medium is detected by a densitometer, and shading correcting data for making the density of the colored recorded area constant based on the detected density are stored in a shading data memory. A controller reads the stored shading correcting data and controls the intensity of the laser beam generated by the semiconductor laser based on the shading correcting data for thereby compensating for variations in the level of an image signal due, for example, to intensity irregularities of the laser beam applied to the thermosensitive recording medium and irregularities of the speed at which the thermosensitive recording medium is scanned with the laser beam.

摘要： Image data representing one pixel line and supplied from a line memory are divided by a dividing circuit into three sets of image data which are stored in respective line memories. A switcher is controlled by a timing signal from a controller to successively supply the image data from the line memories to a thermal head driver. Based on the supplied image data, the thermal head driver enables a thermal head to record three lines on a thermosensitive recording medium. The thermosensitive recording medium now records thereon a high-quality image free of coarse image textures which has recorded image areas dispersed in one pixel interval in the direction in which the thermosensitive recording medium is fed.

摘要： A thermal recording apparatus capable of preventing in advance a thermo-sensitive recording medium or the apparatus from being excessively heated when the apparatus is defective in operation. When a failure in operation of a polygon mirror is detected by a scanning sensor, when a failure in operation of a motor is detected by an encoder or when jamming or the like of a thermo-sensitive recording medium S is detected by a pair of feed sensors, a controller outputs a malfunction signal to a solenoid. The solenoid, activated at all times, is de-activated by the malfunction signal thereby to cause the shielding plate to cut off a laser beam L. Thus, even if a failure in operation of the thermal recording apparatus is developed, the thermo-sensitive recording medium S and the thermal recording apparatus can be prevented from being excessively heated with the laser beam L.

摘要： A light beam is modulated in accordance with an image signal, which is made up of a series of image signal components representing an image recorded on a recording medium, and the modulated light beam is caused by a light beam scanning system, which includes a rotating polygon mirror, to two-dimensionally scan a recording material, the image being thereby reproduced on the recording material. The light beam modulated in accordance with image signal components of the image signal, which correspond to positions lying along each scanning line on the recording medium, is utilized to scan along a plurality of scanning lines on the recording material such that parts of adjacent scanning lines on the recording material may overlap one upon the other. The intensity of the light beam is changed each time the light beam scans along one of the plurality of the scanning lines on the recording material. Each scanning line composed of the plurality of the scanning lines on the recording material is thereby prevented from having an appearance which is not sharp and the sharpness of the image reproduced on the recording material is kept high.

摘要： In a radiation image read-out apparatus, a stimulable phosphor sheet, on which a radiation image has been stored, is exposed to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. The emitted light is photoelectrically detected and converted into an image signal representing the radiation image. An ultraviolet lamp is provided, which produces ultraviolet rays such that energy from the ultraviolet rays is approximately uniformly stored on a stimulate phosphor sheet. The image signal is corrected in accordance with information about the characteristics of shading. The information about the characteristics of shading is corrected in accordance with a signal detected from a stimulable phosphor sheet, on which the energy from the ultraviolet rays have been approximately uniformly stored.

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.

摘要： A scanning read-out apparatus comprises a device for detecting the scanning speed of a light beam and generating a scanning speed signal, and a device for calculation between a read-out signal detected by scanning of a read-out objective and the scanning speed signal and for generating a corrected read-out signal representing the result of the calculation. A coefficient for correction of the read-out signal is adjusted by forcibly fluctuating the scanning speed of the light beam on a read-out objective for correction coefficient adjustment, generating a correction signal by multiplying the scanning speed signal by an arbitrary coefficient, correcting the read-out signal by using the correction signal, extracting a signal of a noise component caused by the forcible fluctuation from the corrected read-out signal, finding the coefficient at which the extracted signal becomes the minimum, and using the coefficient thus found as the correction coefficient.
