Abstract:
An image forming apparatus is provided. The image forming apparatus includes a latent image carrier on which a latent image is formed, a line head that exposes the latent image carrier, and a developing section that develops the latent image. The line head includes a substrate, a light emitting element disposed on the substrate in a first direction, and a wiring installed on the substrate so as to be withdrawn from one end of the substrate in a second direction perpendicular to or substantially perpendicular to the first direction. The one end is disposed to be the developing section side.
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:
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 reading apparatus includes a drive unit that is mounted on a carriage having an image reading sensor, which is moved with respect to an original, mounted thereon and moves the carriage. The drive unit includes: a motor; a gear train for transmitting rotation of the motor so as to move the carriage; an encoder sensor for reading a code wheel fixed to a rotary shaft of the motor; and a support member for holding the motor. The encoder sensor is urged against a part of the support member by a resilient member, to be thus fixed to the support member.
Abstract:
An image scanning device, an image forming apparatus including the image scanning device, and a method of controlling image quality in the image scanning device are provided. The image scanning device includes a document board on which documents to be scanned are placed, a scanning unit which is installed on a lower portion of the document board to be linearly reciprocated, and comprises a scanner including a light guide for irradiating light to the documents, and light emitting devices that are separated from both ends of the light guide and irradiate light, and an image sensor for receiving the light emitted from the scanning unit, wherein, loss of the light emitted from the light emitting devices is compensated for by increasing intensity of electric current supplied to the light emitting devices as a distance between the light emitting devices and the light guide increases.
Abstract:
A multi-beam luminous source apparatus, an optical scanning apparatus, and an image formation apparatus are disclosed. The multi-beam luminous source includes a first member for supporting a coupling lens and a second member for supporting a control substrate that supports a Vertical Cavity Surface Emitting Laser (VCSEL). The first member and the second member are joined with a screw at a reference plane that perpendicularly intersects an optical axis of the coupling lens. The second member includes a base member A for supporting the control substrate and a base member B that includes a branch mirror, a convergent lens, and an optical detection sensor.
