<p>PURPOSE:To provide a winding roller which accurately grasps the forward end of a recording paper for winding, in a device to record an image through reciprocation of a recording paper to a recording position a plurality of times. CONSTITUTION:A device having a hollow cylinder body 11 having a slit opening 11c and a cam 13 to grasp a recording paper 1 arranged therein in a manner to press the recording paper against the inner surface of the hollow cylinder body 11 is used as a winding roller 10. The outer surface of the hollow cylinder body is formed such that the frictional force of a central part is increased to a value higher than those of two end parts. This constitution more firmly fixes the central part of a recording paper than the two ends thereof when the forward end of the recording paper 1 is grasped by the cam 13 to wind it around the outer periphery of the hollow cylinder body 11 and corrects the posture of the recording paper to an accurate state by applying a tension thereon for winding even when the recording paper is in a skew state.</p> |
