PROBLEM TO BE SOLVED: To provide a feeding mechanism of sheet, with a reduced area occupied by a hopper on an apparatus capable preventing jamming when taking out sheets such as envelopes from the hopper and feeding the envelopes to the next process and to provide an one-unit type feeder having the feeding mechanism. SOLUTION: A hopper portion 2 is constituted to set envelopes 3 to be stacked therein, and a bottom portion 22 of the hopper portion 2 has an opening 23 of a predetermined size for forcibly pulling out the envelopes 3 downward therefrom. For pulling out the envelopes, air suction portions 41 is disposed at an elevator portion 4 to suck and pull out the envelopes 3 when the elevator portion 4 is lowered. Carrier belts 9 are disposed to be parallel with each other on both sides of the elevator portion 4 in a lowering direction of the elevator portion 4. When the elevator portion 4 is lowered, the carrier belts 9 forcibly separate the envelopes 3 from each other. The above mechanisms, and a control unit 13 or an air pump 14 or the like are equipped in one movable casing.
