<p>PURPOSE:To have stable sheet feeding by furnishing a frictional separation member at its sheet contacting surface with a hole or a groove as stretching in the direction across the sheet feeding. CONSTITUTION:A W-groove 4 consisting of two continued V's is provided at the sheet contacting surface of a frictional separation pad 2. When sheets 3 are accommodated at a sheet accommodating lever 6, they are pressed to a suction roller 1 by a spring 8. When this suction roller 1 rotates, the sheets 3 are paid off toward the frictional separation pad 2. This pad 2 does not feed the lower situated sheet of eventually double fed sheets due to friction with sheet 3, and only the upper one of the sheets is sucked. At this time, the under surface of the sheet is squeezed by the abovementioned W-groove 4 to get rid of starch etc., which will drop into the groove 4. Therefore, no starch etc. will exist between the sheet and pad 2 to prevent drop of the friction force between the two, which should achieve stable separated feeding of sheets.</p> |
