Abstract:
An optical unit assembly is provided with an optical system including an optical component for irradiating a target object with light and receiving the reflected light, a casing for accommodating the optical system, a supporting frame for supporting a part of the casing, and a height adjusting member having a supporting surface for supporting another part of the casing and placed between the supporting frame and the casing. The height adjusting mechanism is slidable between the supporting frame and the casing with a supported state of the casing by the supporting frame substantially maintained, and the supporting surface includes at least a first supporting surface set at a specified first height position and a second supporting surface set at a second height position different from the first height position.
Abstract:
Provided is an image reading apparatus including: an image reading sensor which reads an image from an original; and a mounting portion which mounts the image reading sensor, wherein the image reading sensor includes a positioning portion which is brought into contact with the mounting portion and adjusts the relative position of the image reading sensor with respect to the mounting portion; and a pressing portion which presses the positioning portion so as to bring the positioning portion into contact with the mounting portion.
Abstract:
An image sensor includes: a case that extends in a longitudinal direction; and a first positioning member that is disposed at one end portion in the longitudinal direction of the case, the first positioning member positioning the case in the longitudinal direction.
Abstract:
An image reading device capable of correctly reading an image on a document is provided without the need to increase the size of an upper cover, etc. of the device. A CIS (Contact Image Sensor) is supported by holders and support shafts to be movable toward the upper cover (rib) and is biased toward the rib by compression springs. In this configuration, the rib for holding the document is not required to be installed as a movable component and there is no need to provide a space for allowing the rib to move or providing the upper cover with a mechanism for allowing the rib to move, which can avoid the need to increase the size of the upper cover.
Abstract:
A handheld print-on-demand digital device. The device comprises a pagewidth inkjet printhead and a platen assembly operatively positioned relative to the printhead. The platen assembly comprises: a planar platen member for supporting print media; a print media transport roller located on a first side of the platen member for feeding print media past said printhead; and a cutting mechanism located on a second opposite side of the platen member for severing the print media. The cutting mechanism includes a transport assembly driven by a threaded rod. The transport assembly has a body for traversing across the print media and a cutting edge fixed to the body for severing the print media during a traverse of the body.
Abstract:
When a cover portion covers a document table, a document transporting unit is positioned relative to a reinforcing member in the horizontal direction so that the document transporting unit is movable in the vertical direction, and a first vertical positioning member comes into contact with the document table of a reading unit or the periphery thereof to position the document transporting unit in the vertical direction based on the position of the document table. A document height regulating member is positioned relative to the reinforcing member in the horizontal direction so as to be movable in the vertical direction, and a second vertical positioning member comes into contact with the document table to position a regulating member in the vertical direction based on the position of the document table.
Abstract:
A line-imaging lens condenses a light beam from a light-source unit in one direction to form a line image. An optical deflecting unit deflects the light beam passing through the line-imaging lens. An imaging optical unit images the light beam deflected by the optical deflecting unit in a spot shape on a scanning surface to be scanned. An adjusting unit adjusts a position of irradiation of the light beam from the light-source unit on the optical deflecting unit.
Abstract:
An apparatus and methods of use for adjusting a sliding guide rod for an imaging device of a flatbed scanner to improve scanner skew misalignment comprising an attachment member movably mounting the sliding guide rod at one end thereof to one side of the flatbed scanner so as to allow skew-adjusting movement of the sliding guide rod at an opposite end thereof relative to the flatbed scanner and a skew adjustment assembly attached to an opposite side of the flatbed scanner and movably coupling and supporting the opposite end of the sliding guide rod to the opposite side of the flatbed scanner and being actuatable to cause the sliding guide rod to undergo skew adjustment relative to the flatbed scanner to correct scanner skew misalignment of the imaging device. The skew adjustment assembly includes a skew adjustment bracket mounted to the opposite side of the flatbed scanner and movably coupled to and supporting the opposite end of the sliding guide rod to the opposite side of the flatbed scanner and a tension spring and a plurality of bracket locking fasteners coacting with the skew adjustment bracket and movably actuatable relative thereto to move the sliding guide rod to undergo the skew adjustment relative to the flatbed scanner.
Abstract:
An image capture and processing device includes an image sensor integrated circuit. A plurality of analogue-to-digital converters (ADC's) are connected to the image sensor integrated circuit to convert analogue signals generated by the image sensor integrated circuit into digital signals. Image processing circuitry is connected to the ADC's to carry out image processing operations on the digital signals. A print head interface is connected to the image processing circuitry to receive data from the image processing circuitry and to format that data correctly for a printhead.
Abstract:
In a line head, a plurality of light emitters are arrayed on a substrate in a first direction. Each of the light emitters is operable to emit a light beam. In a rod lens array, a plurality of rod lenses are arrayed in the first direction, and each of the rod lenses is adapted to focus the light beam emitted from an associated one of the light emitters onto a target surface. The substrate and the rod lens array are attached to a holder elongated in the first direction. Positioning members are provided at both end portions of the holder in the first direction. A relative position between the substrate and at least one of the positioning members is variable in a second direction perpendicular to the first direction.
