<p>Two first follower rollers (A: A1, A2), two first follower rollers (B: B1, B2), and one first follower roller (C) are arranged relative to a single first transportation roller (4). The first follower rollers (A1, A2, B1, B2, C) are rotatably supported at a downstream side end section of holding sections (8a-8e). The holding sections (8a-8e) are arranged in the main scan direction, pivotably supported by supporting shafts (81). The holding sections (8a-8e) and the supporting shafts (81) are assembled together with springs (9) (to be hereinafter mentioned) to form a holder (8) as a single component and then fixed to a main frame (1) by the supporting shafts (8). One end of each spring (9) is fixed to the intermediate section of a holding section (8a-8e) of the holder (8). The other end of the spring (9) is fixed to the frame (1).</p> |
