Abstract:
A scanning head comprises a support member for supporting the head in pressing contact with a platen. The support member has lower strength portions spaced longitudinally of the head, and higher strength portions alternate with the lower strength portions. The support member is easily bendable at the lower strength portions, and the higher strength portions are urged by springs toward the platen. Thus, the head can come into intimate pressing contact with the platen even if the surface flatness of the support member as a whole is not strictly realized.
Abstract:
A method for fabricating a coplanar full width scanning array from a plurality of relatively short scanning subunits for reading and writing images. The subunits are fixedly mounted in an end-to-end relationship on a flat structural member with the subunit surfaces containing the scanning elements all being coplanar even though at least some of the subunits have varying thickness. This is accomplished by forming from a photopatternable thick film layer one or more keys on the subunit surface having the scanning elements and associated circuitry and positioning the keys into keyways produced from a photopatternable thick film layer on a flat surface of an alignment fixture. A conformal adhesive bonds a structural member to the assembled subunits to form the full width scanning array.
Abstract:
A process for fabricating a full width scanning or printing array in which plural smaller scanning or printing chips are bonded end-to-end onto an glass substrate using a photocurable adhesive to form a subassembly, following which the subassembly is inverted and joined to a second substrate having a conductive surface using a conductive heat activated adhesive.
Abstract:
An image reading apparatus includes: a contact glass provided at an upper surface of a main body of the apparatus to set a manuscript thereon, an image sensor being positioned below the contact glass and having a reading surface on contact glass side for reading an image from the manuscript on the contact glass, a carriage supporting the image sensor accommodated in a sensor container formed to have a recess open to the contact glass side, a rail member slidably supporting the carriage, and a biasing member biasing the image sensor to the contact glass side via a biased portion adjacent to the reading surface of the image sensor. An upper end of the biasing member is positioned below the contact glass and above the lower surface of the image sensor.
Abstract:
An image reading apparatus includes: a contact glass setting a manuscript thereon; an image sensor extending in a first direction and having a reading surface which faces the contact glass for reading an image from the manuscript on the contact glass; a rail member extending inside the apparatus main body in a second direction perpendicular to the first direction; a carriage having a sensor container to contain the image sensor, a taper end portion formed in an end portion in the first direction to become smaller in height toward the end side, and an opening formed in the bottom of the sensor container on the taper end portion side; a biased portion adjacent to the reading surface of the image sensor in the second direction; and a biasing member biasing the image sensor toward the contact glass via the biased portion.
Abstract:
A movable carriage includes a mechanism configured to hold a sensor unit so as to allow the sensor unit to displace with respect to the carriage. The mechanism allows the sensor unit to displace with respect to the carriage in a rotational direction centering on a shaft parallel to a moving direction of the carriage and disposed above a reading area of the sensor unit, and in a vertical direction.
Abstract:
A scan bar assembly includes an illuminating unit including a first length; a photosensor array including a second length; and a first spacer member and a second spacer member, each of the first and second spacer members including: an inner side that is proximate the photosensor array; and an outer side that is distal to the photosensor array, wherein a distance between the inner side of the first spacer member and the inner side of the second spacer member is greater than the second length and less than the first length.
Abstract:
A digital camera includes an image capture assembly; a print media transport assembly; a pagewidth ink jet printhead; a roll of print media; an internal chassis serving as a frame on which the image capture assembly, the print media transport assembly, and the printhead are directly supported; and an external casing completely encasing therewithin the internal chassis. The external casing is openable, and the internal chassis together with the assemblies and printhead supported thereon are removable from the external casing. The internal chassis is provided as an integral frame configured with pre-molded fittings adapted to receive and support the assemblies and printhead.
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.
