Abstract: A reading apparatus includes a reading unit and a movement-restriction unit that restricts a movement of the reading unit. The reading unit includes a reading portion for reading an image, a holding portion that holds the reading portion. The holding portion has a first surface. The reading unit further includes a sliding portion that moves in contact with the movement-restriction unit. The sliding portion has a second surface facing the first surface. A first region is provided between the first surface of the holding portion and the second surface of the sliding portion so as to form a predetermined gap.

Abstract: An image scanning apparatus includes: a platen; scanning unit configured to scan an image from the document placed on the platen; and document retaining parts provided at positions corresponding to at least two sides of the platen and configured to prevent the document from curling away from the platen.

Abstract: A medium mounting device includes a medium mounting portion for placing a medium in a stacked state in a first direction, and a medium regulating portion arranged to be rotatable relative to the medium mounting portion. The medium regulating portion is arranged to regulate an edge portion of the medium when the medium regulating portion is in a rising state relative to the medium mounting portion. The medium regulating portion in the rising state is arranged to abut against the medium to rotate and retreat when the medium is taken out in a second direction different from the first direction.
