ABSTRACT:
A paper sheet stripper device of the type used in a paper sheet dispenser, such as a bank note dispenser, in which sheets of paper are sucked by a suction head assembly one by one and passed to a conveyer assembly by the swinging action of the suction head assembly. The improvement proposed is the use of a vacuum source for generating a constant reduced pressure for sucking operation, instead of the conventionally used vacuum source which fluctuates between positive and negative pressures. A valve is interposed between the suction head assembly and the vacuum source so that the suction head assembly communicates with the vacuum source only when the suction head assembly is swung from a sucking position at which it engages with a lower portion of the first sheet of a bundle of paper sheets to a take-up position at which the sucked paper sheet is passed to the conveyer assembly.
