The present invention provides an image input apparatus. The image input apparatus includes a board having an image sensor; a supporting member having a first supporting portion and a second supporting portion; a first fastening member; and a second fastening member. The image input apparatus is characterized in that the board is rigidly secured on the first supporting portion of the supporting member with the first fastening member installed in the first supporting portion, and the board is movably supported on the second supporting portion of the supporting member by the second fastening member installed in the second supporting portion.
Abstract:
An optical unit including a lens unit including a lens and an optical element configured to receive a light beam focused by the lens, and a support member configured to support the lens unit. Cutouts are provided on joint surfaces of the lens unit and the support member, respectively, such that the cutouts on the joint surface of the lens unit match the cutouts on the joint surface of the support member. The cutouts are configured to accommodate a jig inserted thereinto and rotated to move the lens unit relative to the support member and adjust a position of the lens unit in a direction parallel to an optical axis of the lens.

PROBLEM TO BE SOLVED: To improve the quality of a contact image sensor unit by preventing deformation of a light guide.SOLUTION: The contact image sensor unit of this invention comprises: a light source 10 for lighting a document; a bar-shaped light guide 11 for guiding light from the light source 10 to the document; a rod lens array 12 which forms an image of reflected light from the document, on a photoelectric conversion element 13; a sensor substrate 14 having the photoelectric conversion element 13 boarded thereon; a frame 15 on which they are mounted and which has a positioning part 200 for mounting the light guide 11; and a holder 16 which detachably and slidably supports a part of the light guide 11 in the longitudinal direction and which is detachably mounted to the positioning part 200.
Abstract:
PROBLEM TO BE SOLVED: To provide a curvature adjusting mechanism capable of preventing color shift deterioration without changing an adjustment state of scanning line curvature against disturbance after the adjustment of the scanning line curvature by fixing the relative position relation between a mirror of the scanning line curvature adjusting mechanism and a holding means for the mirror in a main scanning direction. SOLUTION: The curvature adjustment unit including the mirror configured to reflect light deflected by an optical deflecting means deflecting light emitted from a light source in a predetermined direction, a holder means configured to hold the mirror, a support member provided to the holder means to hold the mirror, and a pressure means configured to flexibly deform a reflecting surface of the mirror in a normal direction relative to the reflecting surface is provided with a fixing means fixed to at least a portion of the mirror, configured to abut against at least a position of the holder means including the support member, the relative position between the mirror and holder means in the main scanning direction being fixed.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical unit capable of regulating a magnification by providing a cut-out part to allow a wide range regulation. SOLUTION: The cut-out parts 39, 44 having respectively small cut-out parts 39a, 44a are formed respectively in a lens holding member 33 and a lens unit holding member 34, a head part 45 of a jig is inserted into the small cut-out parts 39a, 44a, to be rotated along an arrow mark direction, and the lens holding member 33 and the lens unit holding member 34 are thereby moved relatively along an optical axis L direction. The relative moving direction between the lens holding member 33 and the lens unit holding member 34 can be changed by rotating the jig counterclockwise or by rotating the jig clockwise, according to this manner.

Abstract:
PROBLEM TO BE SOLVED: To provide an image scanner capable of suppressing image deterioration caused by temperature variation, without impeding productivity. SOLUTION: A substrate 22 having an image sensor 21 mounted thereon includes a round hole 22A and an oblong hole 22B. A bracket 23 includes a support section 23A having a screw hole 23C, and a support section 23B. When mounting the bracket 23 onto the substrate 22, first a screw 24 is screwed through the round hole 22A to the screw hole 23C, thereby fixes the substrate 22 onto the support section 23A. Next, a screw 25 is screwed through the oblong hole 22B to the screw hole 23C disposed on the support section 23B, and the substrate 22 is supported by the screw 25. COPYRIGHT: (C)2005,JPO&NCIPI
