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.

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 scanning head comprises a support member (2) for supporting the head in pressing contact with a platen (26). The support member has lower strength portions (A) spaced longitudinally of the head, and higher strength portions (B) 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 (27) 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 contact image sensor (CIS) (201) is incorporated into a drive belt (203) attached to the length of the CIS, resulting in a more compact scanning mechanism and in lighter and smaller scanning devices. The CIS (201) is forced to traverse the document by a drive mechanism (235) that pulls the entire belt and CIS across the document while maintaining the tension necessary to keep the document in the narrow depth of focus. This mechanism provides a uniform force on the CIS, reducing the possibility of yawing motion, and keeps the document in focus through the tension on the drive belt. The combined CIS and transport mechanism power requirements can be supplied by standard computer interfaces. The mechanism also hides the internal workings of the scanner behind a drive belt (203) that is the size of the platen window (301). The drive belt can either be printed with instructions or markings to indicate document placement, or left blank.
Abstract:
A sheet conveying apparatus and an original reading apparatus according to the present invention can reduce a load of a drive system for rotating a convey rotary member and can be made compact. The apparatus comprises an original convey roller 1 rotatably supported by a frame 5, and a CS holder 3 rockably held by a CS holder rotation shaft 3a regulated (in a thickness-wise direction of an original) by a CS holder rotation shaft holding portion 5a of the frame 5 and adapted to hold a CS 2 in a confronting relation to the original convey roller 1. The CS 2 is urged against the original convey roller 1 by an urging spring 4.
Abstract:
La présente invention concerne un scanner de tout type de documents, utilisant une rangée de capteurs optiques, dont l'axe de lecture est en lecture directe sur le document (15) sans aucun contact sur une surface, comprenant un système de détection automatique du parallélisme du document (15) introduit, un rouleau d'entraînement dudit document (15) ; la rangée de capteurs (12) ayant l'angle réglable autour du rouleau d'entraînement, ce qui permet de régler l'angle d'introduction dudit document. Le présent système permet, en outre, une force d'introduction nulle des documents.
Abstract:
A process for fabricating a full width scanning or printing array (3) in which plural smaller scanning or printing chips (5) are bonded end-to-end onto an glass substrate (10) using a photocurable adhesive to form a subassembly (4), following which the subassembly is inverted and joined to a second substrate (6) having a conductive surface (8) using a conductive heat activated adhesive.
Abstract:
A raster scanner (10) with laser (15) for generating a scanning beam (25) and compact, folded optical system for transmitting the beam to the object to be scanned. The optical system includes a modulator (27) for modulating the beam in accordance with video image signals and a rotatable polygon (35) for scanning the beam across the object to be scanned. The laser is supported at one end in a part-spherical bearing (58), permitting pivoting of the laser about a point (P) coincident with the optical axis (0) of the scanner, and at the other end by screw type adjustors (81) which are used to ad- justably displace the laser about the pivot point and so align the axis of the laser beam with the optical axis of the scanner. Scanner operating circuits are provided including a circuit enabling one or both of the scan detectors to serve as a light meter when aligning the laser.
