A feeding apparatus for material sheets, comprising:a hopper having a hopper outlet opening upward or downward and storing material sheets vertically stacked in layers toward the hopper outlet; a sucking member capable of moving into and out of said hopper through the hopper outlet and adapted to attract and deliver a leading material sheet which faces the hopper outlet as said sucking member moves into and out of said hopper; support members for restraining escaping of the material sheets in said hopper at side edges of the material sheets; rows of stoppers formed on said support members, supporting the side edges of the material sheets stacked in said hopper, and securing a gap between the leading material sheet to be delivered by means of said sucking member through the hopper outlet and the next material sheet immediately adjacent to the leading material sheet; introduction passages formed between said individual stoppers of said stopper rows and capable of introducing the outside air into the gap during the delivery by means of said sucking member; and restrainer members formed individually on said stoppers and adapted to restrain escaping of the overlying material sheet when the material sheet is delivered and caused to slip out of the hopper outlet by means of said sucking member.
