摘要： Regardless of a relative installation position error between a light source and a photosensitive material, or of a deviation from a properly preset value of rotation speed of a photosensitive material, images are obtained with minimum loss of image quality and excellent reproducibility. The number m of light-emitting elements to make up a unit and the distance between adjacent pixels formed on the photosensitive surface are adjusted such that the width of the pixel groups is ⅓ mm or less, which is a period that the periodic image noise is not recognized as stripes.

摘要： Laser elements are arranged in two dimensions in an elongated region which is longer in the horizontal direction than in the vertical direction, wherein n laser elements are arranged in the horizontal direction, while m laser elements in the vertical direction, where n>m. The anode wiring extends to a direction which is inclined to the horizontal direction and the cathode wiring extends to another direction inclined to the horizontal direction, thereby the anode wiring and the cathode wiring crossing with each other. The anodes of m laser elements in maximum arranged in the direction of the anode wiring are connected to an anode wire, while the cathodes of m laser elements in maximum arranged in the cathode wiring are connected to a cathode wire. Accordingly, even if the array is longer in the horizontal direction and a large number of laser elements are aligned in the horizontal direction, the wiring resistance and electrostatic capacitance of each wire forming the oblique matrix wiring can be small and the operation delay of the laser element can also be small.

摘要： A plurality of lasers (having openings 170) are formed at predetermined positions at equal intervals on at least two main scanning lines on a semiconductor substrate 100. The lasers have each a predetermined beam diameter and take different positions in the main scanning direction, thereby providing a two-dimensional surface emitting laser array emitting laser beams through a lens system to form a pixel line with no gap on the main scanning line of an image formation face moving in the sub-scanning direction. The two-dimensional surface emission laser array is used to provide a laser beam scanner, a laser beam recorder, and a laser beam recording method.

摘要： Incident signal beam pulses are transmitted by an on-state region, and an optical path for the signal beam pulses is spatially switched in an optical switch. Signal beam pulses transmitted by the on-state region of the optical switch are detected at a pixel corresponding to a transmitting region of a photo-detector equipped with a plurality of pixels. A timing computation unit acquires position information of a pixel at which a predetermined signal beam pulse has been detected, on the basis of a result of the detection conducted by the photo-detector, and computes timing of arrival of a predetermined signal beam pulse at the optical switch on the basis of the position information of the pixel and time when a region corresponding to the pixel is brought to an on-state.
