Guide apparatus for biaxial shifting motion and uniaxial turning motion

A guide apparatus for biaxial shifting motion and uniaxial turning motion, which comprises:

• a biaxial shifting motion guide mechanism for supporting a second member so as to be movable relative to a first member in a constant posture state along biaxial lines intersecting at right angles with each other;
• and
• a pivot supporting mechanism disposed on said biaxial shifting motion guide mechanism at an opposite side of said first member, for pivotably supporting said second member, wherein:
• said biaxial shifting motion guide mechanism comprises a first guide rail secured to said first member, a first movable block connected through a plurality of rolling members to said first guide rail so as to be movable, a second guide rail secured to said first movable block so as to intersect said first guide rail and a second movable block movably connected through a plurality of rolling members to said second guide rail;
• and
• said pivot supporting mechanism comprises a first ring and a second ring, said first ring being secured to said second movable block and said second ring being coupled through a plurality of rolling members with said first ring so as to be rotatable relative thereto and being secured to said second member.

An apparatus for biaxial shifting motion and unaxial turning motion, which comprises:

• a base;
• a table;
• a biaxial shifting motion guide mechanism for supporting said table so as to be movable relative to said base in a constant posture state along biaxial lines intersecting at right angles with each other;
• and
• a pivot supporting mechanism disposed on said biaxial shifting motion guide mechanism at an opposite side of said base, for pivotably supporting said table, wherein:
• said biaxial shifting motion guide mechanism comprises a first guild rail secured to said base, a movable block connected through a plurality of rolling members to said first guide rail so as to be movable and a second guide rail connected through a plurality of rolling members to said movable block so as to be movable in a direction intersecting said first guide rail;
• and
• said pivot supporting mechanism comprises a first ring and a second ring, said first ring being secured to said second guide rail and said second ring being coupled through a plurality of rolling members with said first ring so as to be rotatable relative thereto and being secured to said table.
