Abstract:
PROBLEM TO BE SOLVED: To more effectively strip various media from a belt in an apparatus useful for printing. SOLUTION: The apparatus useful for printing includes a roll 244 including an outer surface 248; a roll 220 including an outer surface 222; the belt 210 including an inner surface 214 and an outer surface 212; a first nip 202 formed by contact between the inner surface 214 of the belt 210 and the outer surface 222 and contact between the outer surface 212 of the belt 210 and the outer surface 248; and a stripping mechanism having a stripping member 296. The stripping member 296 can be positioned to the first nip 202 so as to vary a pressure applied by the outer surface 212 of the belt 210 against the outer surface 248 downstream from the first nip. The media are stripped from the outer surface of the belt 210 after exiting from the first nip 202. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a sheet feeder capable of changing inclination of a sheet support tray on which a sheet stack is placed. SOLUTION: A sheet support tray 210 on which a sheet stack is placed is supported by two tray elevators 220, 230. Each of the tray elevators can independently make the sheet support tray 210 ascend and descend to consequently change inclination of the tray 210. It is possible to provide a paper feeder capable of corresponding to ream weight of various paper sheets, types and curls by controlling the height and the position of the stack.
