摘要: To separate sheets from a stack, for example being fed upwardly, two separating stages are provided: one stage is formed by driven third feed roller (28) located immediately above fixed element (30), rubber block. If, chance, should be fed, the then to second which includes (16) which, example, may drive roller, and first (20) therebeneath can freely rotate in feeding direction. It secured shaft one-way clutch, preventing reverse rotation. impart limited rotation (20), thereof rocked backwardly an eccentric (50, 52) coupled (18) drives entire apparatus. stack height-adjustable sensing deflection of upon engagement with topmost sheet controlling switching electric elevator motor, raising accordance sensed deflection.
