PROBLEM TO BE SOLVED: To provide an envelope feeding device used in a stencil printing machine capable of precluding a misfeed and wrinkling of a flap, in the case where stacked envelopes are fed one by one from the uppermost one. SOLUTION: The envelope feeding device is equipped with an envelope feeder table 21 capable of elevating and sinking on which envelopes with their flaps folded up are stacked and side guides 22 installed on the sides in the width direction perpendicularly intersecting the envelope transporting direction for restricting the sides of the stacked envelopes. The arrangement includes an air suction type transporting mechanism 25 installed over the feeder table 21 for transporting the uppermost one of the stacked envelopes pa by attracting through air sucking and a deterring member 23 which has a determent surface 23b located approximately on a level with the transporting undersurface 56a of the air suction type transporting mechanism 25 and is positioned in the rear about the transporting direction of the transporting mechanism 25. The stacked envelopes Pa are pinched by a constant pressure in the vertical direction between the transporting surface 56a of the transporting mechanism 25 and the determent surface 23b of the deterring member 23 and the feeder table 21 so that the envelopes Pa are held approximately in the horizontal attitude.
