Definitions

  • the present invention relates to a sheet guide apparatus which guides a conveyed sheet to a front lay.
  • the sheet is not always flat.
  • the front edge of the sheet may deform by, e.g., waving, warping, or curling. If the sheet deforms in this manner, it does not abut against a front lay but may ride over it.
  • a sheet guide apparatus of this type is provided with a sheet pressing device, downstream of a feedboard in a sheet convey direction, which straightens a deforming sheet fed onto the feedboard.
  • the sheet can be abutted against the front lay reliably, positioned by the front lay, and corrected from traveling skew, so that the sheet can be transferred to a sheet transfer device reliably.
  • the sheet pressing device is a sheet pressing plate.
  • the sheet pressing device guides a sheet within a wide range in a convey direction and a direction perpendicular to the convey direction. Hence, if the sheet is thin, deformation occurring in the thin sheet can be corrected. If the sheet is thick, when thick sheets are conveyed to overlap like scales, a preceding sheet may raise the sheet pressing plate, so that the next sheet that follows cannot be appropriately guided to the front lay. As the sheet and sheet pressing plate rub against each other, the sheet surface can be damaged easily. Particularly, when the sheet is a film or the like that can readily be damaged, this sheet pressing plate cannot be employed.
  • the guide member is a roller.
  • the roller presses a preceding sheet through point contact the next sheet that follows can be reliably guided to the front lay.
  • an impact generated upon abutment of the thin sheet against the front lay can form wrinkles in the sheet, and deformation occurring in the sheet cannot be corrected.
