The first and second arcuate parts are symmetrical to each other and contact a paper. A pick-up housing supports the pick-up rubber, which are attached around the circumference thereof. A first shaft opening and a second shaft opening are formed opposite to each other in the pick-up housing and are eccentrically disposed with respect to a center of the pick-up housing. A pick-up shaft is engaged with one of the first shaft opening and the second shaft opening of the pick-up housing, and is capable of rotating. The pick-up shaft is engaged with the first shaft opening of the pick-up housing for the first arcuate part of the pick-up rubber to pick up a paper. The pick-up shaft is engaged with the second shaft opening of the pick-up housing for the second arcuate part of the pick-up rubber to pick up a paper.
