摘要： An image recording apparatus modulates a laser beam based on an image signal and a reference clock, and then controls a polygon mirror to irradiate the laser beam on a surface of a photosensitive material. A reference clock generating circuit generates a reference clock having a frequency in proportion to a main scanning speed of a beam spot which is changed during each scanning due to a characteristic of an f.multidot..theta. lens. The reference clock generating circuit includes a line memory which has a bit per address and stores a relationship between an incident angle .theta. of the laser beam on the f.multidot..theta. lens and an image height of the whole valid scanning area, an address counter for designating the addresses serially at a fixed speed so that the data stored in the line memory can be read out address by address serially from a starting point to a finishing point of the valid scanning area, a waveform shaping circuit for generating a clock pulse from the bit data from the line memory, and a multiplying circuit for multiplying a frequency of the clock pulse by an integer of no less than 2.

摘要： A table made of a planar member has a suction groove for sucking and holding a recording medium on a surface thereof. A part of the sucking groove is perforated to form a suction hole. The suction hole is connected to a vacuum pump. The table includes three position determining pins that are in contact with two mutually orthogonal sides of a recording medium. The position determining pins are configured to ascend and descend by driving of an air cylinder between a descending position in which an upper end of the position determining pins is lower than a surface of the table and a position determining position in which the upper end of the position determining pins is higher than the surface of the recording medium mounted on the table. It is therefore made possible to provide an image recording apparatus capable of executing highly accurate image recording by preventing deformation of the recording medium.

摘要： A light beam passing through a first image-forming system is deflected by a deflector. The deflected light impinges upon a second image-forming system which comprises a scanning lens and an anamorphic lens. The scanning lens and the anamorphic lens are disposed in this order from the deflector side. The light beam passing through the anamorphic lens is finally focused on a surface to be scanned with no curvature of field.

摘要： In an optical beam scanning apparatus in which an optical beam from a light source impinges upon a deflecting system and a deflected optical beam from said deflecting system scans a surface-to-be-scanned through a scanning lens in a main scanning direction, with a curvature of image surface correction method of the present invention, curvature of image surface is reduced without improving the surface accuracy of the scanning lens. A lens holder (14) is freely movable on an optical base (3) along a guide (15). When an adjustment screw (16) is manipulated, the lens holder (14) is moved so that a collimator lens (12) is moved along an optical axis (OA) and positioned. As the collimator lens (12) is moved, the degree of parallel of an optical beam which is emitted toward a galvanometer (30) is changed and the shape of an image surface is adjusted, so that the image surface is positioned within the depth of focus of the optical beam scanning apparatus over an entire scanning range. Hence, it is possible to perform drawing with an excellent image quality.

摘要： A first image-forming system includes first and second lens systems which are disposed from a light source to a deflector respectively. The first lens system has a positive power along a second direction so as to converge a diverging light beam from the light source onto the deflector with respect to the second direction. With respect to a first direction being perpendicular to the second direction, the first lens system has zero or a negative power while the second lens system has a positive power so that the focal point of the first image-forming system is located at the light source. Thus, a collimated light beam in the first direction from the first image-forming system is directed to the deflector.

摘要： An image recording apparatus includes a scanning part for recording a plurality of unit images individually on a plurality of recording media, the plurality of unit images being to be superimposed on each other to form a single objective image. The scanning part causes the plurality of unit images to be in different positions. Defects appear in different positions of the plurality of unit images, and are prevented from coinciding with each other in the objective image.
