Abstract: A sheet feeding apparatus can perform appropriate separation corresponding to the type of sheet without an actuator which changes the separation action of a separation unit. For this purpose, a separation unit includes a first inclined part and a second inclined part, each having different inclination angles, and selects, in accordance with the type (stiffness, thickness, or the like) of sheet to be fed, either one of the first inclined part or the second inclined part as an inclined part used in separating sheets by lifting/lowering a tray, and separates sheets, so that appropriate separation can be performed in accordance with the type of sheet with a simple configuration.

Abstract: There is provided a sheet feeding apparatus which can perform appropriate separation corresponding to the type of a sheet without being newly provided with an actuator which changes the separation action of a separation unit. For this purpose, a separation unit 105 includes a first inclined part 105a-1 and a second inclined part 105a-2 each having different inclination angles, and selects, in accordance with the type (stiffness, thickness, or the like) of a sheet to feed, either one of the first inclined part 105a-1 or the second inclined part 105a-2 as an inclined part used in separating sheets by lifting/lowering a tray 101, and separates sheets, so that appropriate separation can be performed in accordance with the type of a sheet with a simple configuration.

Abstract: An inkjet recording apparatus includes a platen holding a recording medium at a position opposed to a recording head, a suction generating member for suctioning the recording medium to the platen, a first recessed portion provided at a region on the platen and connected with the suction generating member, where the region faces a scanning area of the recording head, and a second recessed portion provided at a position on the platen and connected with the suction generating member, where the second recessed portion is provided on the downstream side of a region opposed to the scanning area and provided at a position corresponding to an end portion of the recording medium to be conveyed.

Abstract: An inkjet recording apparatus includes a platen configured to support a recording medium at a position facing a recording head, a suction portion arranged at the platen and configured to suck the recording medium, an ink receiving portion arranged at the platen and configured to receive ink discharged on a region beyond an end of the recording medium, a negative pressure producing portion configured to produce a negative pressure to be applied to the suction portion and the ink receiving portion, and a communication portion causing the suction portion to communicate with the ink receiving portion at the outside of a conveyance region of the recording medium.

Abstract: An ink-jet recording apparatus includes a platen provided with a suction-collection section which sucks in and collects ink discharged deviating from an end portion of recording medium. The ink-jet recording apparatus includes a suction force generation unit for collecting ink configured to enable the suction collection section to generate a suction force, a collection flow path connecting the suction collection section to the suction force generation unit for collection, and a flow path control unit configured to vary an sectional area of the collection flow path. The sectional area of the collection flow path is varied according to an image forming time or a type of the recording medium.

Abstract: An ink jet printer includes a platen including an attraction portion for attracting a sheet and a sheet support surface in which an collection opening for collecting ink discharged outside the sheet is formed, a negative pressure generation mechanism configured to be used in common to generate a negative pressure to be supplied to each of the attraction portion and the collection opening, a first duct configured to connect the negative pressure generation mechanism and the attraction portion, a second duct configured to connect the negative pressure generation mechanism and the collection opening, and an adjustment mechanism configured to ununiformly change a negative pressure to be supplied to the attraction portion through the first duct and a negative pressure to be supplied to the collection opening through the second duct.
