Abstract

PURPOSE:To perform high-accuracy printing free of misregistering, bleeding or the like, by a construction wherein a printing bed is moved in the moving direction of a squeegee by a distance corresponding to the elongation of a screen. CONSTITUTION:The motive power of a motor 17 is transmitted to a speed reduction gear 19 by a driving belt 18, and a squeegee 15 is moved in a fixed direction by a chain 20, whereby an ink 16 on a screen 14 fitted to a frame 13 is pushed out onto a body 12 to be printed. To compensate for an elongation of the screen 14 generated at this time, a belt 23 provided separately from the driving belt 18 is driven by the motor 17, and with a speed reduction by a speed reducing gear 21, a printing bed 11 is moved by a distance corresponding to the elongation of the screen 14 in the direction of elongation, through a gear 22 and a rack 25. As a result, even when the screen is elongated due to the movement of the squeegee 15, the elongation is absorbed by the movement of the printing bed 11, so that normal printing can be performed.
