Title:
LATERAL AND LONGITUDINAL MOVEMENT AND ROTATION SUPPORTING MECHANISM OF STAGE
Document Type and Number:
Japanese Patent JP2940663
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a lateral and longitudinal movement and rotation supporting mechanism of a light weight and a low cost, by forming a supporting unit making the inner side support plate side and the outer side support plate side as the installing part, and installing plural supporting units between a support board and a stage.
SOLUTION: While the installing part 10 of the inner side support plate 5 is installed to the frame of a support board 1, the outer side support plate 6a at the upper side is installed to the frame of a stage 2, so as to support the stage 2 on the support board 1. Although the stage 2 is limited by the moving strokes of the supporting units 3, the stage 2 is supported to the support board 1 allowable to move freely, that is, to move laterally and longitudinally, and to rotate, to the support board 1, by balls 8 held to holding members 7. At least the stage 2 is formed in a frame shape, a window 4a is formed at the center, and the window 4a is made in a through space not disturbed by the supporting units 3 and the like.
