Abstract
PURPOSE: To make it possible to regularly feed sheets of paper one by one by selecting the coefficients of a friction of rotary friction member, a guide plate coming into contact with the leading end of the sheet of paper, and a friction plate with each sheets of paper to be in the relationship of the rotary body>friction plate> guide plate.
CONSTITUTION: The device is constituted in such a manner that when the coefficients of friction of a friction roller 10, a friction plate 14 and a guide plate 9 with sheets 7 of paper are represented by μ1, μ2, and μ3, and the coefficient μ4 between the sheets of paper, the relationship of μ1>μ2>μ3>μ4 is estabilished. By thus constituting the device, a frictional force is acted between the friction roller 10 and the lowermost sheet of paper, and it is acted most strongly on the lowermost sheet of paper. The sheet 7 of paper passes between the guide plate 9 and the friction roller 10 while being defined by the guide plate 9, and introduced between the friction plate 14 and the friction roller 10. In this case, since the coefficients of respective parts with the sheets of paper are in the predetermined relationship, only the sheet of paper which abuts against the roller 10 is delivered preferentially, and the sheets of paper of the second layer and thereafter are successively stopped. Thus, the double delivery is stsictly prevented.
