SHEET SEPARATOR, SHEET SUPPLY DEVICE AND SHEET PROCESSOR USING THIS SHEET SEPARATOR

PROBLEM TO BE SOLVED: To excellently separate the uppermost sheet from the second sheet and sheets thereafter, in regard to sheets loaded and stored in a sheet storage part. SOLUTION: This sheet separator separates the uppermost sheet from the second sheet and sheets thereafter stored in the sheet storage part 1 capable of loading and storing sheets, and has an air suction source 2 capable of sucking air, an air duct 3 forming an air flowing passage between the air suction source 2 and the vicinity of the uppermost sheet in the sheet storage part 1, and a regulating member 4 arranged in a sheet side end part of the air duct 3 and regulating a suction attitude of the uppermost sheet when sucking the air by the air suction source 2. The regulating member 4 has a suction part 5 sucking the sheet by contacting with the sheet when sucking the air by the air suction source 2, and at least a part of the suction part 5 has a variable part 5a displaced or deformed so that the peripheral end side of the uppermost sheet becomes obliquely upward more than an inside area.
