摘要： An image reading apparatus includes a document platen on which a document is to be stacked, a pressing sheet having flexibility, a conveyance unit provided in a base member, an open portion provided in the base member and rotatable in a first direction with respect to the base member to open at least a part of the conveyance path, and a rotation member rotatable in the first direction with respect to the base member. The pressing sheet presses the document against the document platen. The conveyance unit forms a conveyance path within which the document is to be conveyed. The reading unit reads the document conveyed by the conveyance unit. The open portion retains one end of the pressing sheet in a longitudinal direction. The rotation member retains the other end of the pressing sheet in the longitudinal direction.

摘要： In a printing apparatus, a platen configured to support a sheet to be printed includes an ink receiver configured to receive ink discharged from a print head. The ink receiver includes a plurality of first ink grooves and a plurality of second ink grooves configured to guide the received ink, the second ink grooves having a tilt angle greater than that of the first ink grooves. The platen includes an absorber configured to absorb the ink received by the ink receiver, the absorber being arranged on a back side of the ink receiver.

摘要： An image reading apparatus comprises a moving unit on which a reading unit is mounted and which slides on a guide, and a driving unit mounted on the moving unit and includes a pinion gear meshing with a rack which extends in a scanning direction and is disposed between the pinion gear and the guide. A slide contact portion between the guide and the moving unit includes a first slide contact portion on the rack side and a second slide contact portion. The first slide contact portion includes a first surface being inclined so as to displace the moving unit toward the rack. The second slide contact portion includes a second surface preventing the moving unit from being displaced toward the rack.
