PURPOSE:To avoid the strain, folding, clogging, etc. of the thin paper by providing a free roller on a feed roller. CONSTITUTION:A sensor mechanism 4 is set into a housing, and feed rollers 7 and 8 are set at front and rear parts of a sensor reading position at the center of the bottom surface of the mechanism 4. Then free rollers 13 and 15 are provided on the rollers 7 and 8 respectively. The roller 7 is revolved at a slightly lower speed then the roller 8. The difference of speed between these rollers 7 and 8 is controlled to prevent previously the strain, bending, folding, etc. of the thin paper 3. |
