Abstract
A scanner apparatus includes: a holder configured to hold a line sensor unit; a first spacer and a second spacer disposed on both sides of the line sensor unit in a longitudinal direction and configured to come into contact with the transparent plate; and a biasing unit configured to press the holder toward the transparent plate between the first spacer and the second spacer in the longitudinal direction. The line sensor unit and the holder are coupled together on both sides of the biasing unit in the longitudinal direction. A force applied to the holder by the biasing unit is transmitted from the holder through two coupling portions to the line sensor unit, thereby biasing the first spacer and the second spacer to the transparent plate.
