PURPOSE:To prevent a friction roller from contacting with printing sheet which is engaged on a platen at one side by forming a stopper on an arm, and making the end face of a stop screw which is mounted on a frame via a gap oppose against the stopper. CONSTITUTION:When the position of a friction roller 2 is not disposed equally at a distance from the left and right arms 1a such as when the width of a printing sheet 11 is narrow, a deflection of a roller shaft 2a occurs, thereby moving the arm 1a toward an arrow F. A stopper 5 prevents the roller shaft 2a from deflecting further in contact with the end face of the screw 6, and preventing the roller 2 from contacting at one side. |
