Abstract (en)

[origin: EP1975735A1] A sheet supplying device (LT) which supplies a sheet (P), including: a sheet supplying tray (31) which stacks a bundle of sheets; a first air blowing section (40) which blows air against a side of the bundle of sheets stacked on the sheet supplying tray (31); a second air blowing section (50) which blows air from downstream of the bundle of sheets in a sheet conveyance direction, onto a leading section of the sheets; a vacuum conveyance section (60) which vacuums an uppermost sheet of the bundle of sheets and conveys the sheets one by one; a shielding member (45) which shields air blown from the first air blowing section (40); a vacuum detection sensor (PS1) which detects that a sheet has been vacuumed by the vacuum conveyance section (60); and a control section which controls the shielding member (45) to open so that air generated by the first air blowing section (40) is blown to the bundle of sheets.
