装置。[Claims for Utility Model Registration] In a document reading device that focuses reflected light from an illuminated document on an image sensor such as a CCD via an imaging lens and reads the image, a holding member to which the image sensor is fixed is attached to the lens. An adjustment mechanism is provided that includes an eccentric member that adjusts the image sensor in the Y-axis direction while facing the block, and an elastic pressing member that presses the holding member against the lens block, and the lens block is set on the main body support part. An image sensor adjustment device characterized in that the lens block is provided with an adjustment mechanism that fixes the lens block to a positioning receiving portion so as to be adjustable in the Z-axis direction.

Claims

[Scope of utility model registration request]

In a document reading device that focuses reflected light from an illuminated document on an image sensor such as a CCD via an imaging lens and reads the image, a holding member to which the image sensor is fixed is placed so that the image sensor faces the lens block. X, Y while
An adjustment mechanism including an eccentric member for axial adjustment and an elastic pressing member for pressing the holding member against the lens block is provided, and the lens block can be freely adjusted in the Z-axis direction with respect to a positioning receiving part set on the main body support part. An image sensor adjustment device characterized in that an adjustment mechanism for fixing the lens block is provided on the lens block.
