PURPOSE:To increase the working efficiency and precision by installing a screw shaft and a transfer shaft equipped with a positioning piece, a lever and a screw piece and allowing said screw shaft and the screw piece to be freely engaged and disengaged by the turn the lever, and allowing the positioning piece to be adjusted through one-touch operation. CONSTITUTION:A positioning apparatus 1 serves for positioning each frame member F1-F4 of a panel and is arranged along two side edges (a) and (b) having the corner part C1 of a working boad T. When a lever 6 is sprung-up by 90 deg., the engagement between a screw piece 7 and a screw shaft 3 is released, and therefore a transfer shaft 2 can be adjusted freely by the lever 6. When the screw piece 7 is engaged with the screw shaft 3 by pushing-down the lever 6, adjusted to the scales m1 and m2 formed onto the top plate 12 of the working board T, the longitudinal movement of the transfer shaft 2 is restricted. Therefore, after a positioning piece 5 is position-adjusted to every screw pitch, each frame member F3, F4 is position-adjusted with respect to other frame members F1 and F2 arranged onto the respective receiving plates 13 and 14, by each apparatus 1. |
