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 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 method for fabricating a coplanar full width scanning array (40) from a plurality of relatively short scanning subunits (20) for reading and writing images. The subunits are fixedly mounted in an end-to-end relationship on a flat structural member (30) with the subunit surfaces containing the scanning elements (12) 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 (14) one or more keys (18, 38) on the subunit surface having the scanning elements and associated circuitry and positioning the keys into keyways (28, 39) produced from a photopatternable thick film layer (23) on a flat surface of an alignment fixture (24). A conformal adhesive (36) bonds the structural member to the assembled subunits to form the full width scanning array.

Abstract:
PROBLEM TO BE SOLVED: To reduce the pitch unevenness of scanning exposure due to the vibration at the mounting part of a scanner with a spring in an image forming apparatus having a scanning optical apparatus (scanner) 2. SOLUTION: The image forming apparatus provided with the scanning optical apparatus 2 which is mounted by being inserted substantially horizontally with respect to the body of the image forming apparatus has: a plate spring member 11 which energizes in substantially vertical direction the body of the image forming apparatus for fixing the scanning optical apparatus on the body of the image forming apparatus in a state that the scanning optical apparatus 2 is inserted in a predetermined insertion position of the body of the image forming apparatus, or the end part 10 provided on the scanning optical apparatus in the insertion direction of the scanning optical apparatus; and a cushion member 13 which pressurizes the body of the image forming apparatus and the scanning optical apparatus via the plate spring member 11.

Abstract:
PROBLEM TO BE SOLVED: To provide an image reading apparatus capable of mounting two linear image sensors on a contact image sensor module without upsizing an original platen. SOLUTION: The image reading apparatus includes: an original platen; a support member for supporting an end of the original platen in the subscanning direction from its lower part; a contact image sensor module that includes the first linear image sensor and the second linear image sensor whose length is shorter than that of the first linear image sensor and has a first projection extended in the subscanning direction and houses the second linear image sensor in the first projection; and a carrying means for carrying the contact image sensor module in the subscanning direction, and when the contact image sensor module is carried up to the end in the subscanning direction, the support member is contained in a space existing in the main scanning direction of the first projection.
