Abstract
A sheet guiding device guides sheets which are to be fed out to a device for processing the sheets. The sheet guiding device includes a sheet loading unit on which the sheets are loaded, a pair of restriction members for contacting a side edge of the sheets loaded on the sheet loading unit to restrict a position of the sheets, and a support unit for supporting the restriction members such that the restriction members are movable obliquely relative to a direction in which the sheets are fed.
Claims19
A sheet guiding device for guiding a sheet to be fed to means for processing the sheet, said device comprising:
- sheet loading means on which a sheet is loaded, the sheet having one of a plurality of predetermined sizes;
- a pair of restriction members for contacting side edges of a sheet loaded on said sheet loading means, thereby restricting a position of the sheet;
- linking means for linking movement of one of said restriction members to movement of the other of said restriction members, said linking means including a pair of pinions which are in mesh with each other, and a pair of racks respectively engaging said pair of restriction members, each of said racks being in mesh with one of said pinions, said linking means linking said restriction members such that a distance between said restriction members varies;
- and
- support means for supporting said pair of restriction members such that each said restriction member is movable in a line obliquely relative to a direction in which the sheet is to be fed, wherein said support means moves said restriction members such that each said restriction member is brought into contact with a substantially center portion of a side of the sheet away from ends of the sheet without regard to which of the plurality of predetermined sizes corresponds to the size of the sheet.
