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： This invention is concerning a multibeam exposure scanning method and apparatus, and a method of manufacturing a printing plate. The problem to be solved is that angular small convex points are to be stably formed through multibeam exposure. The above problem is to be solved by a multibeam exposure scanning method for engraving the surface of a recording medium by simultaneously emitting beams to expose and scan the same scanning line two or more times. The multibeam exposure scanning method includes: exposing a first region with a first amount of light and exposing a second region with a second amount of light in a single scanning operation, the first region being adjacent to a target planar shape to be left on the exposure surface of the recording medium, the second region surrounding the first region; and, in at least one of a second exposure and scanning operation and succeeding exposure and scanning operations, exposing and scanning the second region with a larger amount of light than the amount of light used in the first exposure and scanning operation.

摘要： A light beam deflector for recording an image at a recording medium, at which a light beam modulated in accordance with image information passes through an incidence face of a cubic prism which is driven to rotate, the light beam deflector reflecting the light beam at a reflection surface, emitting the light beam through an emission face, and deflecting and scanning the light beam. An astigmatic difference correction surface is structured at at least one of the light beam incidence face and emission face of the cubic prism. The astigmatic difference correction surface is set with an inclination angle and inclination direction that are suitable for correcting astigmatism which arises due to the light beam passing through the incidence face, being reflected at the reflection surface and passing through the emission face.

摘要： The present invention provides an inner drum exposure device. Based on image signals from two light sources, two laser beams, which are each made independent, modulated, and projected, are polarized and integrated with a polarized light beam splitter, and then made into right-handed and left-handed circularly polarized light and projected towards a scanning optical system. This right-handed and left-handed circularly polarized light incident from the light source side optical system are converted to two linearly polarized laser beams that cross each other with a quarter wavelength plate arranged on the optical path of the scanning optical system. After this, the two laser beams converted with the quarter wavelength plate into linearly polarized light that cross each other are ejected, each from differing positions such that the primary rays of the projected beams are parallel, with a uniaxial crystal.

摘要： A multi-beam exposure apparatus of the present invention includes a two-dimensional light modulator which is configured to project plural exposure beam spots onto an exposure surface, the plural exposure beam spots being arranged in parallel with the scanning direction while two-dimensionally arrayed; and a pixel block shifting member which divides the plural beam spots into plural blocks in the scanning direction and projects the plural exposure beam spots onto the exposure surface by shifting a relative position between the blocks in a direction orthogonal to a scanning direction, and thereby the scan-exposing of a space between the exposure beam spots in the direction orthogonal to the scanning direction is performed with the exposure beam spot of another block. According to the multi-beam exposure apparatus, the number of dots which can simultaneously be exposed in the direction orthogonal to the scanning direction can be increased.
