PURPOSE:To print a resist at a time when a printed board is manufactured accurately by a method wherein a work charged onto an aligning stage is temporarily fixed and stopped, positional displacement with the position of printing is detected and adjusted, the work is attracted to a carrying-in table, printing is conducted at the position of printing, the table is retreated while leaving the work, and the work is carried out by an carrying-out table. CONSTITUTION:When a work W is charged into an aligner 70, the work is stopped by the front-rear section positioning mechanisms of a spare aligner 30, and set onto the top faces of left and right aligning stages 72 and a carrying-in table 165. Positioning marks on the work are projected onto a monitor TV by cameras 76, and displacement with the position of printing is detected, and adjusted by the aligning stages 72. The work is attracted and lifted by the carrying-in table 165, and made to travel between printing stages 243 divided into two, and printing is conducted. The rear end section of the work is elevated after printing and the carrying-in table is retreated, a carrying-out table 195 is positioned to the lower section of the work while being synchronized with the retreat of the carrying-in table, and the work is lifted and carried out. The movement of the cameras 76 is measured by the number of step pulses of a motor as a moving means. |
