Problems solved by technology

Thus, for the adhesive material used to bond the ends of the mirror, it is necessary to use a relatively soft adhesive material that allows thermal expansion or contraction of the mirror, but it may be difficult to rigidly bond the mirror

Embodiment Construction

[0048] Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0049] A first embodiment of the present invention is an optical scanning device having a plurality of pre-scanning optical systems consisting of light sources emitting light beams, collimating lenses for converting divergent light beams emitted by the light sources into substantially parallel light beams, and Aperture to trim the light beam, and a cylindrical lens for linear imaging of the light beam in the main scanning direction, the optical scanning device is provided with a deflection section for deflecting the light beams from a plurality of pre-scanning optical systems in the main scanning direction (deflector), and single or multiple imaging lens groups respectively used to image the deflected light beams from the pre-scanning optical system on the scanning surface of an optical housing, wherein there are provided for reflecting and guiding each l...

Abstract

The invention provides an optical scanner for scanning object using irradiating light through at least one mirror irradiating object with a first end and second end attached on the shell using light generated from light source, wherein the first end of at least one mirror is movably supported by shell and the second end of at least one mirror is bonded to the shell.

Description

technical field [0001] The present invention relates to an optical scanning device, an image forming device, a mirror, a casing, a mirror attachment method, a mirror arrangement adjustment device, and a mirror arrangement adjustment method. Background technique [0002] For color image forming apparatuses such as laser printers, digital copiers, and laser FAXs, polygon mirrors for deflecting scanning beams from a light source and forming regular polygons are provided, and for imaging the scanning beams deflected by the polygon mirrors on the surface of a photoconductor The optical components (scanning lens and mirror), and the photosensor set outside the effective exposure area on the side where scanning starts, to determine the starting position of writing. [0003] In these color image forming apparatuses, it is necessary to overlap a plurality of colors when forming a color image. A method for overlaying an image with a plurality of colors on one photoconductor and a met...
