PROBLEM TO BE SOLVED: To provide a printing agent filling apparatus for preventing printing failure by preventing the generation of air bubbles caused by the mixing of air with a printing agent and capable of performing good reciprocating printing. SOLUTION: A frame 5 is moved in a forward squeezing direction F by a drive mechanism not shown in the drawing. Whereupon, a pair of squeegee blades 1 and 2 are slid and moved on the surface of a screen plate mask 52 while respectively held to about 60°in the attack angleθ1 with the surface of the screen plate mask 52 and the squeegee blade 2 rubs a photosensitive resin 50 in the through-holes 52a of the screen plate mask 52. Then, the movement of the frame 5 is stopped at the completion position of forward printing and, since rearward printing is performed thereafter, the attack angle is reversed as shown by the two-dot broken line in the drawing without separating a pair of the squeegee blades 1 and 2 from the surface of the screen plate mask 52. By this constitution, the mixing of air with the photosensitive resin 50 is not generated and printing failure can be prevented. COPYRIGHT: (C)2003,JPO
