Abstract
An image sensor unit includes a frame storing a linear illuminator that linearly illuminates a document, a rod lens array is used to form an image of light reflected from the document irradiated by the linear illuminator, and a printed circuit board on which a light-receiving sensor that converts light whose image has been formed by the rod lens array into an electrical signal is mounted. In the frame, a lens storage compartment, a linear illuminator storage compartment, and the linear illuminator are adjacently arranged substantially in parallel to each other in a longitudinal direction, with an inter-compartment portion formed in the frame interposed therebetween. At least one pin insertion opening is formed that extends from an inner wall of the lens storage compartment opposing the inter-compartment portion into an outside of the frame and through which a pressing pin is inserted, and in the inter-compartment portion, a face defining the lens storage compartment is formed as a vertical reference face with which a side plate of the rod lens array is brought into close contact for fixing. A notch used for applying an adhesive to the side plate of the rod lens array is disposed co…
