Abstract:
A scanning device includes a scanner body, a scanning unit, a lens unit, a sensing unit, and a fastening unit. The scanner body has a bottom surface that is formed with two slots. 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:
An LED module is mounted on a case frame by fitting three pins formed at a concave portion of the case frame, into holes in the LED module corresponding to the pins. A light-guide plate is fitted into the case frame formed integrally with a bottom cover in a descending direction. The light-guide plate is fixed by a hook provided for the case frame. A space between the light-guide plate and the LED module is prevented by pressing the light-guide plate to the LED module with a pressing spring. Since the light-guide plate is fitted into the case frame in the descending direction and a light scattering sheet is adhered to an outer end surface of the case frame in the descending direction, it is not necessary to reverse the worked product and so the number and time of working processes can be saved.
Abstract:
A mounting structure for an inverter circuit board for a light source lamp of an image reader in which mounting means for mounting the inverter circuit board for a light source lamp of an image reader onto a carriage is located to be operated from the direction in which the carriage moves in one embodiment. The inverter circuit and heat dissipation plate are removably mounted to an end of the full rate carriage. In another embodiment, the circuit board is mounted to the top for access from above the carriage.
Abstract:
Semiconductor chips, such as photosensor arrays in a full-width scanner, are mounted on printed wiring boards. The printed wiring boards are in turn mounted on a second layer of printed wiring board material. The two layers of printed wiring board material are attached so that the seams between adjacent printed wiring boards in each layer alternate in a brick-like fashion. This structure enables arrays of semiconductor chips to be constructed in relatively long lengths, with minimal risk of damage caused by thermal stresses.

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 image forming optical element is provided, in which an incident unit having a first lens face to which a light beam output from an original document (object) is input, an output unit having a second lens face outputting the light beam, and a bent unit connecting the incident unit and the output unit at an angle are integrally formed into a transparent medium. The bent unit has a reflection face reflecting the incident light beam input to the first lens face and guiding the light beam to the second lens face. The incident light beam is collected at any of the incident unit, the bent unit, and the output unit to form an intermediate image of the object, and the intermediate image is formed on the output side of the second lens face to form an erection image of the object.
Abstract:
An image reading device includes a light source; a light guiding member; an imaging optical system that reflects the light, which faces a first direction from the object, in a second direction intersecting the first direction by a reflective plane disposed in the first direction of the object, that makes the light, which is reflected by the reflective plane, converge toward the second direction by an emission portion disposed in the second direction of the reflective plane, and that images an erect equal-magnification image of the object in the second direction of the emission portion; and an optical sensor that is disposed in the second direction of the emission portion of the imaging optical system, and detects the erect equal-magnification image that is imaged by the imaging optical system, in which the light guiding member is disposed at an object side of the emission portion in the first direction.
