IMAGE FORMING APPARATUS Russian patent published in 2019 - IPC B41J2/447 

FIELD: image forming devices.

SUBSTANCE: device contains many semiconductor chips, each of which contains many laser-emitting elements located in a two-dimensional main matrix with M rows and N columns. Elements in each row are spaced at regular intervals A_r, and elements in each column are located at regular intervals a_s. Microcircuits are mounted on a support in such a way that each pair of microcircuits, which are located next to each other in a given direction along the Y axis, transverse to the direction along the X axis, is displaced relative to each other in the direction along the X axis, and, with continuous activation, the emitted laser beams of two microcircuits of this pair conduct on the imaging surface a set of parallel lines that extend in the X direction and are located essentially at equal intervals in the Y direction. In addition to M lines and N columns of the elements of the main matrix, each chip contains at least one additional column on each side of the main matrix, each column contains at least one capable of selectively activating a laser-emitting element, made with the ability to compensate for any bias in the Y-axis direction in the relative arrangement of adjacent chips on the support.

EFFECT: device for imaging is proposed for projecting separately controlled laser beams onto an imaging surface that is movable relative to the device in a given direction along the X axis.
