<p>PROBLEM TO BE SOLVED: To provide a sheet material separation device which can use for a long term by one paper feed roller, by which the friction member of the paper feed roller used to the separation carrying of the sheet material can be replaced with a simple operation without replacing the paper feed roller. SOLUTION: A screw 10 is tightened with a tap 2a of a shaft 2 through a hole 1a-1 of the paper feed roller 1 fixed on the shaft 2. The screw 10 is removed (picture (a)) and the paper feed roller 1 is rotated in an arrow mark direction and also moved to a radial direction along a groove shape space L (picture (b)) and the screw 10 is tightened at the position where a hole 1b-1 is agreed with a tap 2a (picture (c)). Thus, the position between friction members A1 and A2 can be replaced.</p> |
