Claims

[Scope of utility model registration request]

In an optical reading device that irradiates light onto an object to be read and receives light reflected by the object to be read, the object to be read is read,
A light source that irradiates light onto the object to be read, a solid-state scanning element that includes a row of microphoto sensors that receive light reflected by the object to be read, and a solid-state scanning element that reflects direct light from the light source and irradiates it onto the object to be read. An optical reading device comprising a mirror configured to equalize the amount of light reflected by the object to be read in the direction in which the micro photosensors of the solid-state scanning element are arranged.
