Zusammenfassung: | PURPOSE:To enable fine regulation, to enhance printing accuracy on a matter to be printed and to reduce a malfunction rate by providing a jig containing a foil strain gauge to the squeegee attachment part of a screen printer to associate an electric circuit for displaying strain difference of an elastic unit. CONSTITUTION:A platelike elastic unit 4 preferably has an elasticity and excellent recoiling strength. A foil strain gauge 5 having an elasticity for detecting a strain difference is bonded to the rear face of one end of the unit 4 near a contact with a squeegee, and the other end is clamped and bonded to a strain gauge holder block 6 made by a hard plastic and metal. Then, detected right and left strain electric outputs are amplified and digitally displayed as a strain difference. When a parallel regulating jig 7 is mounted on a squeegee attachment 1 to drive a squeegee 2 to print, the right and left strains of the squeegee 2 are detected by the jig 7, and the right and left strain difference is numerically measured by an electric circuit. Thereafter, when the squeegee 2 is not paralleled, it is so regulated by a parallel regulating screw 10 that its numeric value becomes nearly zero. |
