Abstract
PURPOSE: To stabilize the pushing down force of a paper feeding roll to the change in the quantity of forms paper by providing a supporting projection at the vicinity of the gravity position of the forms on the lower part of the forms support plate.
CONSTITUTION: The support projection 16 is provided on the forms support plate 4. Suppose that the force in which the lifting roller 7 pushes up the forms support plate 4 by the force of a spring is P1' are the force in which the paper feeding roller 5 applies to the paper surface of the forms 1 at right angles is P2' and P1 and P2 when the support projection 16 is not provided, respectively. Where, the following two expressions are established by moment balance: P2=P1-G1.L1/t1, and P2'= P1'-G1.t2/t3 Suppose that the accumulated thicknesses T of these forms are used as the lateral axis, the change in P2' is more reduced than P2 change. In other words, the pushing down force of the paper feeding roll 5 can be stabilized to the change of the quantity of forms, and a number of paper feeding events do not occur even when the number of forms are reduced.
