An image sensor unit includes a light condenser that collects light from a reading target object; an image sensor that receives light and converts the light into an electric signal; an elongated housing that houses the light condenser and the image sensor; and an elongated rigid member attached to a side surface extending in the elongated direction of the housing. The side surface of the housing is provided with an attachment protrusion. The rigid member is provided with an attachment hole that penetrates from a surface facing the side surface of the housing to a non-facing surface on the opposite side, and the non-facing surface of the rigid member is provided with a concave. The attachment protrusion is inserted into the attachment hole, and a part of the attachment protrusion is fit into the concave.

An image sensor unit includes: a light source; a rod-shaped light guide; a light condenser that condenses light from an illuminated object; and a frame. The frame includes: a light guide housing chamber that houses the light guide; a light condenser housing chamber that houses the light condenser; and a partition wall provided between the light guide housing chamber and the light condenser housing chamber. The light guide includes: a light incident surface that receives light emitted by the light source; a light diffusing surface that diffuses the light entered from the light incident surface; and an abutment surface abutted to one side of the partition wall, which covers at least a part of the abutment surface of the light guide, where an incident angle to the abutment surface of the light directly reaching the abutment surface from the light diffusing surface is smaller than a critical angle.

A flexible circuit board 3a for mounting a light emitting element has base films 31a and 31b, a wiring pattern 32 formed on a surface of the base films 31a and 31b, and the cover films 33a and 33b that covers the base films 31a and 31b and the wiring pattern 32. At least one of the base film and the cover films 33a and 33b have a substrate 331 and 331a comprising a metal. The cover film 33a and 33b have such surface properties as to produce specular reflection or diffuse reflection of light or has substantially white reflecting films 36 and 333 on a surface of the cover film.

An image sensor using three-color, e.g., R, G, and B light-emitting elements assures a period in which all the three colors are turned on and periods in each of which one light-emitting element is turned off during a scan period per pixel, and integrates and measures amounts of light of the respective periods. An amount of light based on the OFF light-emitting element is calculated based on a difference between the amounts of light during the full light-ON period and each light-OFF period to define an amount of light of the light-emitting element, and light intensity information corresponding to each light-emitting element is obtained based on a total amount of light during the entire scan period per pixel, and the amount of light of each light-emitting element.
