Reading apparatus switching between first optical path and second optical path

A reading apparatus comprising:

• an light emitter that performs irradiation with light;
• a light receiver that receives light reflected from an object to be imaged;
• a first optical path in which specularly reflected light, which is obtained as light emitted by the light emitter is reflected from a first reflection surface so that a front surface of the object to be imaged in an irradiation region is irradiated with the reflected light, and the reflected light is specularly reflected from the front surface of the object to be imaged, is guided to the light receiver as a read image;
• a second optical path in which diffusely reflected light, which is obtained as the light emitted by the light emitter is reflected from a second reflection surface so that the front surface of the object to be imaged in the irradiation region is irradiated with the reflected light, and the reflected light is diffusely reflected from the front surface of the object to be imaged, is guided to the light receiver as a read image;
• and
• a switching section that switches between the first optical path and the second optical path by rotating the light emitter,
• wherein a part of the first optical path and the second optical path is reflected by a common mirror.
