Abstract
Provided is a sheet feeding device having a sheet surface detecting mechanism installed to be movable up and down between adjacent adsorption conveyance belts, and detects a position of the top surface of the sheet by a sheet surface detecting memberthat moves upward higher than the adsorbing surface of an adsorption conveyance belt. The position of the lower surface of the sheet surface detecting memberbeing pushed up by the blown upward sheet is regulated such that the difference in height between the adsorbing surface of the adsorption conveyance beltand the lower surface of the sheet surface detecting memberis smaller than the difference in a height direction between the adsorbing surface of the adsorption conveyance beltand the upper surface of a separation nozzle by a sensor abutting portionthat regulates upward movement of the sheet surface detecting member
