Claims

[Scope of utility model registration request]

In a reversing roller type automatic paper feeding device that works in cooperation with a feed roller and a reversing roller to sequentially pull out sheets of paper placed on a sheet loading table, starting from the lowest sheet, the leading end is formed of an elastic plate. , and its tip portion faces near the paper sheet insertion portion at the contact position with the feed roller and the reversing roller, and the tip portion is arranged so as to be able to approach and separate from the roller surface of the feed roller in a substantially perpendicular direction. A drive mechanism that moves the vapor support toward and away from the paper support in response to the rotation of a feed roller and a reversing roller, and moves the leading edge of the paper sheet that has reached the paper sheet insertion section to the leading edge of the paper support. An automatic paper feeder characterized in that the leading edge of the paper sheet is pressed intermittently against the nine surfaces of the feed row by means of an elastic plate.
