CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims priority under 35 USC 119 from Japanese Patent Application No. 2020-089543 filed May 22, 2020.

BACKGROUND

i) Technical Field

The present disclosure relates to a reading device, an output apparatus, and an image forming apparatus.

ii) Related Art

Japanese Unexamined Patent Application Publication No. 2010-130444 describes a reading device including a second emission unit that emits light for receiving a portion of a specularly reflected light component from a document. The light emitted from the second emission unit is incident on the document at an angle that is not 0 degrees with respect to a reflection angle of a principal ray of specularly reflected light guided toward a light guiding unit.

SUMMARY

A light directing unit may be provided to direct light toward a reading region, and a light guiding unit may be provided to guide light reflected by the reading region. When the relative position between these units is even slightly shifted upon reception of specularly reflected light, the image quality will be changed.

Aspects of non-limiting embodiments of the present disclosure relate to facilitation of positioning of reflecting units that reflect light before and after the light reaches a reading region.

Aspects of certain non-limiting embodiments of the present disclosure overcome the above disadvantages and/or other disadvantages not described above. However, aspects of the non-limiting embodiments are not required to overcome the disadvantages described above, and aspects of the non-limiting embodiments of the present disclosure may not overcome any of the disadvantages described above.

According to an aspect of the present disclosure, there is provided a reading device including an emission unit that emits light; a first reflecting unit having a first reflecting surface that reflects the light emitted by the emission unit toward a document; a second reflecting unit having a second reflecting surface that reflects the light reflected by the first reflecting unit and specularly reflected by the document; a first support unit that supports the first reflecting unit and the second reflecting unit and fixes a relative position and a relative orientation between the first reflecting surface and the second reflecting surface; and a second support unit that supports the first support unit such that at least one of a position and an orientation of the first support unit is adjustable.
