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, a variable member 4 arranged in a sheet side end part of the air duct 3, sucking to a peripheral edge part of the uppermost sheet when sucking the air by the air suction source 2 and deformed or displaced so that the sheet peripheral end side becomes obliquely upward more than an inside area in a sheet suction position, and a driving force applying means 5 for applying driving force to deformation or displacement of the variable member 4 in at least any of suction operation and a suction operation release by the variable member 4.
