Abstract:
Provided is an ink supply cartridge for a printhead assembly having a printhead integrated circuit (IC) and a guide assembly for guiding ink to the IC. The ink supply cartridge includes a first U-shaped top portion defining side walls, and a second base portion for complementarily receiving the first portion so that the side walls define elongate ink reservoirs together with the base portion. The base portion includes an end portion defining a series of air inlets with convoluted winding channels leading to the ink reservoirs, said channels hydrophobically treated to prevent ink escaping from the channels.
Abstract:
An image reading device according to one aspect of the invention comprises: a conveying unit configured to convey a recording medium; a first transmissive portion having a first surface that allows the recording medium to pass the first surface; a second transmissive portion having a second surface on which a recording medium is allowed to be placed; an image reading unit comprising a line sensor extending in a first direction and movable on a second path, the second path continuously extending below the first transmissive portion and the second transmissive portion; and a driver configured to move the image reading unit on the second path. A relative distance between the line sensor and the first surface changes in the second path below the first transmissive portion. The recording medium can be read at positions having the relative distances different one another.
Abstract:
According to an aspect of the invention, there is provided an image reading apparatus including: a first plate including a stationary document reading region; an image reader configured to scan a document on the first plate; a carriage supporting the image reader in a state that the carriage keeps the image reader predetermined distance from the first plate; and a guiding member that makes the image reader move downwardly by contacting an edge of the first plate.
Abstract:
An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.
Abstract:
A height adjustment structure for an image-scanning device. The scanning device has a guiding rod, an optical system and a document panel. The guiding rod and the document panel are fixed relative to each other. The optical system includes a box body and an axial rod bearer that can slide along into the guiding rod. The height adjustment structure includes a first positioning section and a second positioning section. The first positioning section is attached to one side of the box body and the second positioning section is attached to one side the axial rod bearer that faces the first positioning section. The first positioning section and the second positioning section has hooking mechanism, screwing mechanism or teeth-meshing mechanism for fixing the box body relative to the axial rod bearer and hence setting the distance from the box body to the document panel.
Abstract:
An image reader includes a casing, a contact glass plate, a contact image sensor, and a sliding mechanism; wherein the contact image sensor has a housing, a light source attached to the housing so as to face the contact glass plate, a plurality of light receiving elements attached to the housing so as to face the contact glass plate and aligned in parallel in a longitudinal direction of the housing, and a bearing formed integral to the housing at a position below a lower surface of the housing; and the sliding mechanism includes a guide shaft provided on the casing and extending in a short direction of the housing and inserted through the bearing, and an urging member elastically which urges the guide shaft toward the contact glass plate so that the housing is pressed against the contact glass plate.
Abstract:
A printer assembly includes an ink supply mechanism that incorporates a printhead. A platen is operatively connected to the ink supply mechanism. A capping mechanism is mounted on the platen and has an elongate capping arm for moving towards the printhead into a capped position and away from the printhead into an uncapped position. A biasing arrangement biases the capping arm into the uncapped position. A moving arrangement moves the capping arm into the capped position.
Abstract:
A printhead assembly for a camera system that includes an ink reservoir assembly that is mountable on the chassis of the camera system and defines at least three ink reservoirs in which differently colored inks are received. The ink reservoir assembly defines an outlet. A guide assembly is positioned in the ink reservoir assembly to define three discrete ink paths that open at the outlet. A printhead integrated circuit is positioned in the outlet to span the printing path. The printhead integrated circuit defines three sets of inlet apertures, each set of inlet apertures being aligned with a respective ink path.
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:
An image reading apparatus includes a line light source having a light guide plate and red-, green-, and blue-LEDs, for a light transmitting original, and a contact image sensor unit for detecting light from the line light source. The light transmitting original is arranged between the line light source and the contact image sensor unit. The light transmitting original is read by moving the line light source and the contact image sensor unit relative to the light transmitting original. The line light source is moved interlockingly with the contact image sensor unit by the attraction between a magnet provided at both ends of the line light source in the longitudinal direction thereof and a magnet provided at both ends of the contact image sensor unit in the longitudinal direction thereof.
