Abstract
A sensor unit includes an edge detection sensor and an illumination device. The edge detection sensor is disposed in a conveying path of a recording medium and detects a recording medium edge position in a width direction perpendicular to a conveying direction. The illumination device is disposed to face the edge detection sensor in the conveying path and emits light toward the edge detection sensor. The illumination device includes a light source and a diffuser. The light source emits light. The diffuser diffuses the light from the light source and suppresses luminance unevenness.
