PURPOSE:To permit the stable exfoliation by improving the close attached performance of a finger onto a copying drum by arranging an elastic-body supporting shaft for supporting the finger, in turnable ways for an installation body. CONSTITUTION:When, at the position where a supporting shaft 11 is deflected by an angle theta, a finger 10 is pressed onto a copying drum 9, an elastic repulsive force corresponding to the deflection angle theta is applied onto the finger 10, and also when an L-shaped metal fitting 15 is deflected in the direction of arrow G, the close attaching of the finger 10 onto the drum 9 free from gap is compensated. For the deflection in the direction of revolution of the supporting shaft 11 on the L-shaped metal fitting 15, namely in the direction of arrow I, the finger 10 is always kept at a constant posture angle by the turn of a fixed and slidable part 12 in the opposite direction to that of deflection, and a gap is not formed between the drum 9, and the perfect close attached state is maintained. Therefore, the finger 10 can be closely attached onto the drum 9 for the deflection in any direction, and the stable exfoliation of form-sheet 8 is permitted. |
