At least both sides of the recording medium (10) are sandwiched by means of the drive roller (14) and the pinch roller (34), and the recording medium (10) is carried onto the drafting member (12) by the rotation of the drive roller (14). The recording head (22) reciprocatingly shifts in a direction perpendicular to the carrying direction of the recording medium (10) on the drafting position of the drafting member (12). The suction force is generated by the suction device (36) in a predetermined range of the drafting member and surrounding the drafting member (12), and the recording medium (10) is attracted to the drafting member (12). The unevenness guide unit (19) having the suction holes is formed on the drafting member (12), and the recording medium (10) is adsorbed to the unevenness guide unit (19) by means of the suction force of the suction device (36). The unevenness guide unit (19) 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 (10) and concave grooves that are adjacent to the convex stripes, and the floating of the recording medium (10) over the drafting member (12) is prevented by the mutual operation of the suction forces of the unevenness guide unit (19) and the suction device (36).
An inkjet printer, which printer sandwiches at least both sides of a recording medium by means of a drive roller and a pinch roller, and the recording medium is carried to a paper guide at the lower stream side from the upper stream side of a drafting member through the drafting member, and the recording is carried out by means of a recording head on the recording medium at a drafting position of the drafting member, an improved inkjet printer wherein a suction device is provided for generating a suction force in order to force the recording medium to contact a support surface of the drafting member in a print range, and suction holes that communicate with the suction device and an unevenness guide unit are provided on the drafting member.
An inkjet printer, which sandwiches the drive roller and the pinch roller and carries the recording medium to the paper guide at the lower stream side from the upper stream side of the drafting member through the drafting member by the rotation of the drive roller, and performs the recording on the recording medium over the drafting member by means of the recording head, an improved inkjet printer, wherein a suction device is provided for generating a suction force that forces the recording medium to contact with the support surface in a print range of the drafting member, and an unevenness guide unit including a plurality of convex portions arranged in a row is provided on the drafting member or the paper guide that is adjacent to the drafting member, and suction holes that communicate with the suction device are formed on the upper surfaces of the convex portions, and the lower surface of the recording medium is caused to contact tightly on the upper surfaces of the convex portions by means of the suction force of the suction device.
An inkjet printer for printing on a recording medium, comprising:
