Abstract:
A document reading apparatus includes a sensor configured to receive light from a document, an imaging lens configured to form an image of light from the document on the sensor, a first holding member to which the imaging lens is fixed, and a second holding member to which the sensor is fixed, wherein the first holding member and the second holding member are fixed using an adhesive and solder.
Abstract:
An optical system, used for scanning, forms an image using reflective optical surfaces. The system may be telecentric, and may form an image that is reduced in size as compared with the scanned original. Several image-forming optical channels may be combined to form a page-wide scanning array.
Abstract:
An optical scanning device includes a plurality of converging lenses and a plurality of supporting members. Each supporting member supports a corresponding one of the converging lenses. Moreover, the converging lenses are arranged so as to be out of alignment with one another in a main-scanning direction and are arranged in a row in a sub-scanning direction in such a manner that no converging lens interferes with supporting members that support other converging lenses.
Abstract:
A technique is provided which can improve optical characteristics by suppressing the occurrence of an error in attachment of a rotary deflector that deflects a light flux from a light source and scans it in a main scanning direction. There are provided a rotary deflector that deflects the light flux from the light source and scans it in the main scanning direction, an imaging optical system that images the light flux scanned by the rotary deflector onto a specified scanning object, a support part that supports the rotary deflector rotatably, and a positioning part that comes in contact with the support part at plural contact positions and positions the support part, in which a shortest distance between the plural contact positions in an optical axis direction of the imaging optical system is longer than a shortest distance between the plural contact positions in the main scanning direction.
Abstract:
To provide an optical scanning apparatus which is strong against an external stress while suppressing an increase in the number of parts, an inserting portion 6 into which a laser light source unit 1 can be inserted is provided for a frame member 5. In a state where the laser light source unit 1 has been inserted into the inserting portion 6, the laser light source unit 1 and the inserting portion 6 of the frame member 5 are interference-fitted in two positions (front edge side fitting portion 4a and front edge side contact portion 6a; root side fitting portion 4b and root side contact portion 6b) which are away from each other in an optical axial direction.

Abstract:
An image sensor including: light guides for irradiating light onto an irradiated object; a lens that focuses reflected light that was reflected by the irradiated object; a sensor that receives the reflected light that was focused by the lens; and a housing. The housing houses or holds the light guides, the lens, and the sensor, and is formed by integrating a housing metal portion and a housing resin portion.

Abstract:
Warpage and twist of a solid-state image sensing apparatus is controlled, thereby preventing displacement occurring to the solid-state image sensing apparatus when it is mounted on a printed circuit board. The solid-state image sensing apparatus comprises a plurality of outer leads, and the outer leads each comprises a horizontal portion protruding in the horizontal direction from a side face of a package body for encasing a solid-state image sensing chip therein, an end portion extending in a direction orthogonal to the horizontal portion, and disposed directly below the horizontal portion, a mid portion positioned between the horizontal portion, and the end portion, a first bend formed between the horizontal portion, and the mid portion, and a second bend formed between the mid portion, and the end portion.
Abstract:
In a color marking assembly, a series of ROS units are aligned above a photoconductive surface. These units have inboard and outboard mounts connecting them to this assembly. The inboard mounts are attached to a first side of the ROS, and the outboard mounts are attached to a second side of the ROS unit.The inboard mount is an elongated bar extending beyond the height of the ROS unit. This elongated bar has hinged portions on both its top and bottom connections to the ROS unit. The outboard mount has a ball bearing or sphere configuration. This configuration and the inboard mount enable the ROS unit to be easily deskewed when required.
