A vertical correcting operation table structure used for clamping the panel forming printed circuit board consists of vertical bolster wall, correcting operation table fit vertically face to front surface of bolster wall, exposure plate set on window of the operation table. The correcting operation table is supported by several bolster components on the bolster wall and can move on the vertical surface. Each bolster component consists of ball foot wheel fixed on the bolster wall, which a ball in, a contact block fixed the correcting operation table, stretch spring force the surface of contactblock closing to the ball. The moving components are also fit between bolster wall and correction operation table, each of them consists of contact block on correcting operation table and servo wheelon bolster wall. The spring forces servo wheel close to the contact block. Pulse motor drives correcting operation table moving relative to the bolster wall.
