Abstract:
A development device includes an imaging lens and light shielding walls. The imaging lens includes a body part having a constant diameter and both end parts arranged at both ends in an optical axial direction having diameters larger than the body part to capture a reflected light from a document onto an imaging part. The light shielding walls has a space with an interval larger than the diameter of the body part and smaller than the diameters of the both end parts, allowing the body part of the imaging lens to be arranged in the space, and shielding a light in the optical axial direction.

The fastening unit includes two first fastening members disposed respectively within the slots, and two second fastening members engaging respectively and threadably the first fastening members so as to fasten the sensing unit to the scanner body.
Abstract:
A light emitting device (1) includes a light emitting element (2), a substrate (3), a reflecting plate (4), and a screw member (5). The light emitting element is mounted in the substrate. The reflecting plate is arranged on the substrate. The screw member fixes the reflecting plate and the substrate to each other. The substrate includes a first surface (7), a second surface (8) on an opposite side of the first surface, and an applied part (11) on which the light emitting element is mounted. The reflecting plate includes a third surface (9) that comes into contact with the first surface, a fourth surface (10) on an opposite side of the third surface, and an opening portion (6). The opening portion penetrates the reflecting plate and opens on the third surface and the fourth surface. The opening portion has the shape such that an opening space on a side of the third surface of the reflecting plate is smaller than an opening space on a side of the fourth surface of the reflecting plate. The screw member penetrates the first surface of the substrate and the third surface of the reflecting plate from the second surface of the substrate towards an area in which the opening portion of the reflecting plate is not formed and to which the opening portion is near, whereby the screw member fixes the substrate and the reflecting plate to each other.
Abstract:
A lens module includes a non-cylinder lens and a clamping apparatus. The clamping apparatus includes a base, two side parts, and a top part. Two side parts are disposed on two ends of the base to form a containing trough for holding the lens. One end of the top part is connected to one side part and the other end is fixed on the other side part. Two screw holes on the top part allow two adjusting screws to be screwed into for pressing the lens. Two elastic devices provide the elasticity between the lens and the base and the relative height of two sides of the lens is adjusted by turning the two adjusting screws.
Abstract:
An optical reflection panel made of thermosetting plastic material as a substrate is disclosed. One surface of the substrate is coated with an adherent layer and then an optical reflecting layer is formed on the adherent layer as a reflecting surface for reflecting a light beam. The other surface of the substrate is formed with a reinforcing structure. The reinforcing structure serves to increase the mechanical strength of the optical reflection panel and control the deformation amount. The reinforcing structure includes a number of reinforcing ribs extending along the longitudinal axis of the optical reflection panel and a number of reinforcing ribs perpendicular to the longitudinal axis of the optical reflection panel.
Abstract:
An image sensor includes: a lens configured to focus light irradiated toward an object to be read and reflected by the object to be read; a sensor configured to receive light focused by the lens; a sensor board configured to mount thereon the sensor; a board retaining plate, having a casing attachment surface extending in the X direction and a sensor board attachment reference surface that is in contact with the +Y side of the sensor board and is formed in a side surface of the casing attachment surface, and configured to retain the sensor board; and a first casing configured to fix or retain the board retaining plate by fastening of a surface of the casing attachment surface.
Abstract:
A light guide for guiding light from multiple point sources arranged in a first direction (Y1) on a light source board includes a supporting unit including multiple supporting pieces provided to the light source board, arranged at regular intervals in the first direction (Y1), and a light guiding body continuous with the multiple supporting pieces and disposed downstream from the multiple point sources in a light emission direction (L). The light guiding body includes an incident surface, a light emission surface, multiple support ranges in which the supporting pieces are provided, and multiple light transmission ranges adjacent to the support ranges, respectively, in the first direction (Y1), to cause the light to exit the guiding body partly, and the multiple support ranges and the multiple light transmission ranges have substantially the same length in a second direction (X) perpendicular to the first direction (Y1).

Abstract:
An image-reading apparatus that optically reads an original, includes: an illuminating section that illuminates the original with light; an imaging unit that creates pixel data on the basis of reflected light reflected from the original; a moving unit that moves the illuminating section and the imaging unit relative to the original in steps of a fixed distance in a scanning direction that points from one end of the original toward another end of the original; an illumination mode controller that, for each unit step of movement out of one entire scanning movement in the scanning direction performed by the moving unit, controls the illuminating section so that the illuminating section is made to operate in each of a plurality of illumination modes.
