Claims

[Claims for Utility Model Registration] (1) A movable platen is movably supported on a fixed platen via a thrust bearing, and extends and contracts parallel to the fixed platen.
1 drive device and 1 that expands and contracts in the direction perpendicular to it
The driving devices are arranged so that the direction of expansion and contraction is parallel to each side of the movable platen, and each driving device and each side of the movable platen are arranged perpendicular to the direction of expansion and contraction of each driving device. A movable table that is connected via a guide, a bearing into which the guide is slidably fitted, and a rotating member which rotatably connects the bearing and the guide to a drive device or a movable platen. (2) The movable table according to claim (1), wherein the connecting portion of the drive device is arranged at the center of the side of the movable platen. (3) The movable platen is supported on the fixed platen via a thrust bearing, and a through hole is provided that passes vertically through the fixed platen and the movable platen, and when the movable platen moves through the through hole of the fixed platen at its maximum stroke. The movable table is formed by the projected shape of the movement locus drawn by the edge of the through-hole of the movable platen.
