Lens arrays of an image reading device in which lens bodies are arranged in a main scanning direction are connected with a gap therebetween. A plurality of first slit portions and a plurality of second slit portions are provided along the main scanning direction between the lens arrays and an image sensor. The first slit portion includes first light shielding plates that separate optical paths of light passed through the lens bodies. The second slit portion includes the first light shielding plates and a second light shielding plate that restricts an optical path of light passed through a lens body closest to the gap at a gap side. The position of the second light shielding plate in a direction along the optical path at the image sensor side is closer to the lens arrays than the first light shielding plates are.

Image reading device

A first lens body and a second lens body are fixed to, using an adhesive layer, a surface of a lens fixing plate determined by intersection of a straight line in an optical axis direction and a straight line in a longitudinal direction, such that the lens fixing plate in which a lens fixing plate opening is formed in a lateral direction overlaps, when viewed in the lateral direction, at least a portion of a junction at which the first lens body and the second lens body are bonded to each other. A first adjustment member is brought into contact with the first lens body via at least one hole into which the first adjustment member is inserted A second adjustment member is brought into contact with the second lens body via at least one hole and into which the second adjustment member is inserted.

Lens body bonding structure, image reading device, and method for bonding lens body

An image reading device includes a lens array including lenses arranged in a main scanning direction and forming an erect unmagnified optical system to converge light from a reading target, a holder holding the lens array, a light receiver to receive the light converged by the lenses, and slit units. Each slit unit includes three or more light shielding plates each separating an optical path of one lens from an optical path of another lens between the lens array and the light receiver, and side plates disposed on two sides of the light shielding plates in a direction intersecting the main scanning direction and connecting two adjacent light shielding plates. The slit units are arranged in the main scanning direction, and each two adjacent slit units are arranged with a space therebetween for one optical path of one lens.

Mounting bracket for image sensor

For an image sensor that is elongated in a main scanning direction, an image sensor mounting bracket is obtained that suppresses a warp of the image sensor due to the weight thereof. The image sensor mounting bracket includes a fastening element to be fastened to a lateral surface of the image sensor and a fastening element to be fastened to an attachment target object, the fastening element intersecting the image sensor-side fastening element. The fastening element has an image sensor fastening surface abutting the image sensor and having positioning pins, and the attachment target object fastening element has an attachment target object fastening surface abutting the attachment target object and having elongated through holes that elongate in a sub-scanning direction and are arranged in the main scanning direction and the sub-scanning direction.
