Abstract
A sheet attribution detection sensor device includes a light emission element configured to emit incident light to a paper sheet, a light receiving element configured to receive a specular reflection component of reflection light from the paper sheet of the incident light in order to specify a thickness of the paper sheet, and light receiving elements configured to receive a diffuse reflection component of the reflection light in order to specify one of surface roughness and color of the paper sheet.
Claims8
A sheet attribution detection sensor device including:
- a light emission element configured to emit incident light to a paper sheet;
- a first light receiving element configured to receive a specular reflection component of reflection light from the paper sheet of the incident light to specify a thickness of the paper sheet;
- and
- a second light receiving element configured to receive a diffuse reflection component of the reflection light to specify one of sheet surface roughness and paper sheet color.
