A scanner comprising:
- a medium which is conveyed in a first direction along a conveying path;
- an image read unit disposed extending in a second direction perpendicular to the first direction in a plane including the medium;
- a first light emitting unit that emits first light to the image read unit, the first light emitting unit being disposed along an opposite side to the image read unit relative to the conveying path and located upstream from the image read unit in a conveyance direction of the medium;
- and
- a detection unit that detects a length of the medium in the second direction, based on a variation in intensity of the first light received by the image read unit in the second direction.
