PURPOSE:To enable a uniform flat condition to be maintained over the entire part of paper size, by providing a sucker body at a lower position of a plurality of string members stretched between guide members. CONSTITUTION:The string member 3 are wound around and stretched between a pair of roller form guide members 1, 2, and a vacuum-type sucker body 4 is provided at a lower part of the string members 3. At an outside part of each of pulleys 13, 14, a connecting body 18 is engaged to a shaft part 11 through screws so that the connecting body 18 and the shaft part 11 are rotated as one body, and the side surface of the connecting body 18 is friction coupled to the side surface of each of the pulleys 13, 14. Therefore, when a motor 10 is rotated, the tension on the stringer member 3 stretched between the guide members 1, 2 is maintained to be constant. When printing on a paper 8, the paper 8 is placed on the stringer member 3, whereby the paper 8 is attached by the suction generated by the sucker body 4, is maintained accurately at the placed position, and accurate positioning is achieved even when the string members are repeatedly reciprocated. In addition, the paper 8 is maintained in a uniform flat condition on the stringer members 3, and an ink is jetted from a printing head 9 to perform printing. |
