A plurality of image-forming optical elements are disposed such that a part of a field-of-view region of one image-forming optical element overlaps a part of a field-of-view region of an image-forming optical element disposed adjacent to the one image-forming optical element, each of the image-forming optical elements includes: a lens for collecting light scattered by a reading object; an aperture stop for cutting off some of the light collected by the lens; a phase modulating element for modulating phase of light passing through the aperture stop; and a lens for allowing the light whose phase is modulated by the phase modulating element to form an image on an image-forming surface, and the phase modulating elements are loaded such that resolution characteristics of the phase modulating elements in an arrangement direction of the image-forming optical elements are the same among the image-forming optical elements.

Image reading apparatus

A laser output measuring apparatus in which an optical separator is disposed in a position that is rotated by a predetermined angle about an optical axis of a laser beam converged by a lens, and further rotated by a predetermined angle about the optical axis of the laser beam and a straight line perpendicular to an incident surface of the laser beam.

Laser output measuring apparatus

An image reading device including: concave first lens mirrors that are arranged in an array shape along a main scanning direction and that collimate scattered light reflected by an irradiated object and reflect the scattered light as a substantially parallel bundle of rays that are angled in a sub-scanning direction; planar mirrors that reflect light from the first lens mirrors; apertures that are arranged in an array shape and that allow light from the planar mirrors to pass through by way of openings that are arranged in an array shape and that are light-shielded therearound for selectively allowing light to pass through; concave second lens mirrors that are arranged in an array shape into which light from the apertures is incident and that reflect the light from the apertures as converged light; and light receivers that have light receiving areas on which light from the second lens mirrors is incident and that form images that correspond to light from the openings.

Image reading device

Included are a plurality of cylindrical holders having holes into which laser modules are fitted and fixed, respectively; a plate-like base that has a first surface, a second surface opposite to the first surface, and a plurality of through holes through which the laser beams from the plurality of laser modules fixed to the holder pass, the holders abutting against the first surface so as to connect the holes thereof to the through holes of the base, the second surface of the base being arranged with a plurality of lenses corresponding to the through holes; and adhesives applied to outer corners of abutment portions, at which the base and the LD holders abut against each other, for fixing the base and the LD holders to each other.

Light source device

Included are, a module fixing body having a plurality of mounting holes into which laser modules are fitted and accommodated, respectively; an electricity-supplying member having an end provided with electricity-supplying terminals, which are connected to electricity-receiving terminals of the laser module accommodated in the mounting hole; and a cooling member that cools each of the laser modules. A groove in which the electricity-supplying member is accommodated is formed in a surface of the module fixing body, and the cooling member is closely arranged on the surface of the module fixing body.

A cathode ray tube has a three-gun type electron gun. The electron gun includes a cathode, a G electrode, a G electrode aligned in line in this order, the G electrode and the G electrode having beam-passing holes formed therein. A supporting member supports the cathode in position. A GM electrode is added between the G and G electrodes and has a beam-passing hole smaller than the holes formed in the G electrode and the G electrode. The supporting member and the G electrode are formed with measurement holes. The G electrode may also be formed with a measurement hole therein. A measurement element is inserted through the measurement holes to measure a distance between the G electrode and the G electrode, and a distance between the GM electrode and the G electrode.
