Abstract
At least both sides of the recording medium (,) are sandwiched by means of the drive roller (,) and the pinch roller (,), and the recording medium (,) is carried onto the drafting member (,) by the rotation of the drive roller (,). The recording head (,) reciprocatingly shifts in a direction perpendicular to the carrying direction of the recording medium (,) on the drafting position of the drafting member (,). The suction force is generated by the suction device (,) in a predetermined range of the drafting member and surrounding the drafting member (,), and the recording medium (,) is attracted to the drafting member (,). The unevenness guide unit (,) having the suction holes is formed on the drafting member (,), and the recording medium (,) is adsorbed to the unevenness guide unit (,) by means of the suction force of the suction device (,). The unevenness guide unit (,) comprises a plurality of convex stripes disposed in a row which extend in an X-axis direction in parallel with the carrying direction of the recording medium (,) and concave grooves that are adjacent to the convex stripes, and the floating of the recording medium (,) over the drafting member (,) is prevented by the mutual operation of the suction forces of the unevenness guide unit (,) and the suction device (,).
