摘要： A printer for executing recording onto media, comprising a head and a rotary encoder, wherein the head and the media are moved relatively. In the relative movement between the head and the media, the media may be moved relative to the immobile head, or the head may be moved relative to the immobile media. The rotary encoder outputs pulses corresponding to relative positions between the head and the media. The head starts recording onto the media based on the pulses output by the rotary encoder. When the pulses from the rotary encoder have not been output within a predetermined period of time, the printer starts recording onto the media based on a lapse of the predetermined period of time.

摘要： An optical writing apparatus including a semiconductor laser having plural light emitting elements and a single light-receiving element and plural semiconductor laser drive controlling devices. The plural light emitting elements in the semiconductor laser array are driven such that an optical writing operation at a same time per each of plural lines is performed. A commonly used LD drive controlling circuit drives the LD array. An output timing-determining device outputs a switch changing-over signal to either one of respective changing-over switches in a changing-over switch circuit. After an operational delay time of the changing-over switch elapses, an APC signal is output to an APC control section of the LD drive controlling circuit connected to a negative feedback loop formed by a changing-over operation of the changing-over switch circuit. After the completion of the APC operation, the outputting of the switch changing-over signal to the changing-over switch is stopped.

摘要： The printing plate has a carrier layer, a photopolymer layer and a laser-sensitive layer, in particular, a flexographic printing plate for direct laser exposure. The laser-sensitive layer is firstly selectively removed in a laser exposure unit with a laser beam that is moved relative to the printing plate, and the printing plate is subsequently irradiated with UV light at least on the side of the selectively removed laser-sensitive layer. This prevents washing out of the photopolymer layer under the removed regions of the laser-sensitive layer during subsequent developing of the printing plate. Time required for the partial removal of the laser-sensitive layer and the irradiation with UV light and to lower the space requirement and investment costs, different regions of the plate are irradiated with laser beam and with the UV light simultaneously in the laser exposure unit.

摘要： An optical scanning device which performs an exposing operation with respect to a photosensitive material such as a printing sheet, etc., by scanning with laser beams in respective colors modulated according to image data is arranged so as to modulate light beams in respective colors projected from respective light sources of a red LD, a green-color SHG laser unit and a blue-color SHG laser unit by AOMs according to image data. Then, the clock frequency control section adjusts an exposure scanning clock for each of the AOM drivers for driving these AOMs individually. It is therefore possible to suppress an aberration in color caused by a shift in light beams in respective colors which are to be projected onto the same target position.

摘要： A multibeam light source for use in information recording, including a semiconductor laser array provided with a plurality of light emitting points in a single package, in which the plurality of light emitting points are positioned in linear relationship to one another and have an equidistant pitch so as to respectively emit laser beams to be simultaneously scanned over a recording substrate. The position of the semiconductor laser array is adjustable so as to satisfy the relation nullnulltannull1null1/(nnull1)null, where the angle null is defined by two straight lines, the one drawn perpendicular to the primary scanning direction on an image recording substrate and the other drawn through respective centers of the first and n-th laser beam spots formed on the image recording substrate by projecting laser beams emitted respectively from the plurality of light emitting points. As a result, increases in the speed and the density of the information recording are achieved through the formation of suitable laser beam diameters on the recording substrates. Also, excellent recorded images are achieved without visually recognized phase differences between laser beam spots.

摘要： A plate-making method is capable of recording a sharp image on a photosensitive plate, and is applicable to a process operation executed in a light room, while adverse influences caused by laser flares can be hardly received. Ultra-short pulse laser light emitted from a Ti:Al2O3 laser light source is modulated by an AOM (acousto-optic modulating element). The modulated laser light is focused by a collective lens onto a high-sensitive photopolymer layer of a photosensitive plate-making material. The focused ultra-short pulse laser light may cause a photopolymerization reaction in a laser-light-irradiated portion of the high-sensitive photopolymer layer by way of a multiple photon absorption phenomenon, so as to form a hardened portion.

摘要： An object substrate that contains a markingly effective amount of a radiation sensitive marking material such as titanium dioxide is subjected to a patterned pulsed beam of coherent energy having a level of flux density that is at least sufficient to cause the radiation sensitive marking material to change color without degrading the object substrate. The pulsed beam of coherent energy derives its pattern from the instantaneous configuration of individual mirrors on the face of a digital mirror device (DMD) as the energy is reflected from that mirror face. The level of flux intensity at the mirror face is less than the level at which the DMD is at risk of damage or disruption. The level of flux intensity at the object substrate to be marked is sufficient to cause the titanium dioxide to change color, and substantially above the level at which the DMD is at substantial risk of damage or disruption. To accommodate these inconsistent requirements, the cross-section or footprint of a typical pulsed beam of coherent energy is expanded before and condensed after impinging on the mirror face of the DMD. Typically, pulses of coherent energy are serially generated in rapid succession, for example, by a laser, and each pulse possesses a level of flux density that is substantially above the level at which a DMD is at substantial risk of damage or disruption. This permits a DMD to be used to define instantaneously variable patterns or images with which object substrates are marked.

摘要： An image forming apparatus illuminates a pixel formation member with optical energy according to image data specifying a value for each pixel in the image. Some of the optical energy emitted to form a pixel is distributed over surrounding pixels; similarly, a pixel may receive peripheral optical energy that was emitted to form surrounding pixels. The amount of peripheral optical energy thus received is calculated, and the amount of optical energy emitted to form the pixel is adjusted to compensate for the peripheral optical energy, so that the total optical energy received by the pixel has the intended value. Image irregularities are thereby avoided, even if the image formation apparatus employs multiple light-emitting elements with different energy emission distributions.
