<p>The present invention provides a paper separation machine, that can return the two pieces of paper touching with the pick up roller at the same time, when paper of mixing different sizes are feeded into the machine, and can prevent the machine performs inefficiently. The paper separation machine includes pick-up rollers 1, supply rollers 2 and separation rollers 3. And a few rows of paper detecting devices are installed along the paper moving direction A, each row of the paper ditecting device has three sensors mounted perpendicular to the line A and located at the center, left and right side of line A respectively. When the shielding order of the first row sensors is different to that of the second row sensors, the paper separation machine will decide that the feeded paper is abnormal and-return paper 10 to the feed-in port 9.</p> |
