摘要:
In a contact type image sensor including an illumination section including a light source and light guide to illuminate a document, an image sensing element for converting an optical image of the document into an electrical signal, a cylindrical rod lens for forming an optical image on the image sensing element, and a frame for integrally holding the illumination section, image sensing element, and cylindrical rod lens, the light guide has undergone antireflection treatment on a surface thereof on the document side.
摘要:
The present invention relates to an image reading apparatus which has first reading means for reading image information on one side of an original document; second reading means for reading image information on the other side of the original document; image processing means for processing the image information read by the first reading means and the second reading means; and switching means for switching, to either of the first reading means and the second reading means, an input source of the image information to be transmitted to the image processing means.
摘要:
The present invention relates to an image forming apparatus comprising: an exposing means and a developing means. The developing means comprises a plurality of developing devices, a rotating member rotatable while supporting the plurality of the developing devices, and a driving means for the rotation drive of the rotating member for selectively moving the plurality of the developing devices to the developing position such that the driving means transmits driving force to the rotating member via a gear at a drive transmitting position. An angle θe(°) formed by a straight line linking the rotation center of the rotating member and the drive transmitting position and the tangent of the image bearing member at an exposing position in the image bearing member moving direction satisfies the following relationship with the premise that an pressure angle of the gear is α(°) and the image bearing member rotating direction is positive:−α≦θe≦α.

An image reading apparatus includes an image reading unit having an image reader for reading an image; a first original carriage for carrying an original and for reading an original image in contact with the image reading unit, while moving; a second original carriage for carrying an original and for reading an original image in contact with the image reading unit while in a stationary state; a stay provided between the first original carriage and the second original carriage; an urging device for urging the image reading unit toward the first original carriage or toward the second original carriage; a guide portion, provided outside an image reading region, for guiding the image reading unit away from the stay when the image reading unit moves between the first original carriage and the second original carriage; and a member to be slidably guided relative to the guide when the image reading unit moves between the first original carriage and the second original carriage, the member to the guided being disposed at a balanced position in a moving direction of the image reading unit and being substantially in line contact with the guide portion.
摘要:
An image printing apparatus is provided with a plurality of support legs having height-adjusting screws for providing a substantially horizontal support on an inclined installation surface, whereby a flow path is formed to exchanged atmosphere and heat through a gap formed between a lower surface portion and an installation surface.

An engraving processing apparatus includes a laser engraving unit configured to perform engraving processing for forming a recessed portion on a sheet by irradiating a laser beam onto the sheet, and a controller configured to control an engraving processing operation of the laser engraving unit.
摘要:
A sheet processing apparatus configured to bind a sheet bundle includes a folding portion configured to fold the sheet bundle, a sheet processing portion provided upstream of the folding portion and configured to form a groove at a fold position of at least one sheet of the sheet bundle, and a controller configured to control an operation of the sheet processing portion. The controller controls an operation of the sheet processing portion such that a width of a groove formed on a sheet located on an outer side of the folded sheet bundle is larger than that of a groove formed on a sheet located on an inner side of the folded sheet bundle.
摘要:
Provided is an image forming apparatus capable of mounting an internal unit in a main body chassis thereof, in which a position of a sheet conveying portion for conveying a sheet to the internal unit, with respect to the internal unit is adjusted by a first adjustment portion, and a position of a sheet discharge portion which discharges the sheet having an image formed thereon, with respect to the internal unit is adjusted by a second adjustment portion.
