Abstract
A first-side reflected-light detector includes a first light-receiving unit that receives a first light emitted from a first light-emitting unit and reflected on a first side of a recording medium. A second-side reflected-light detector includes a second light-receiving unit that receives a second light emitted from a second light-emitting unit and reflected on a second side of the recording medium. The first-side reflected-light detector and the second-side reflected-light detector are arranged in such a manner that the first light-receiving unit is fixed at a position off from an extension line from the second light-emitting unit in an emitting direction of the second light, and the second light-receiving unit is fixed at a position off from an extension line from the first light-emitting unit in an emitting direction of the first light.
