Abstract
A sensor unit includes a first housing constituting a first conveying face of a sheet conveying passage, a second housing constituting a second conveying face arranged opposite the first conveying face with a predetermined gap, an edge detection sensor detecting a side edge along the sheet conveying direction, and a gap adjuster supporting the first housing movably in a direction in which the size of the gap increases. When, with the first housing arranged at the first position, a sheet with a thickness greater than a reference value passes through the sheet conveying passage, the first housing moves in the direction in which the size of the gap increases as the sheet enters the sheet conveying passage, to allow the passage of the sheet.
