Precision parallel translation system

A precision parallel translation system comprising:

• a base;
• a first pair of guide members parallel to each other spaced apart a predetermined distance on said base;
• first rough drive means for rough movement arranged on said base in parallel relation to said first pair of guide members, said first rough drive means being provided with a first moving member moving in a direction parallel to said first pair of guide members;
• a first table slidably supported on said first pair of guide members, said first table being provided with a first connecting member associated with said first moving member;
• first connecting means support by one of said first moving member and said first connecting member for connecting and disconnecting said first moving member to said first connecting member;
• first fine drive means for fine movement supported on a support member arranged for slidingly moving and fixedly secured relation to said base, said first fine drive means including a movable portion connected to said first table;
• a second pair of guide members parallel to each other spaced apart a predetermined distance on said first table, said second pair of guide members being located perpendicular to said first pair of guide members;
• second rough drive means for rough movement arranged on said first table and located parallel to said second pair of guide members, said second rough drive means being provided with a second moving member moving in a direction parallel to said second pair of guide members;
• a second table slidably supported on said pair of second guide members, said second table being provided with a second connecting member associated with said second moving member;
• second connecting means supported by one of said second moving member and said second connecting member for connecting and disconnnecting said second moving member to said second connecting member;
• and
• second fine drive means for fine movement supported on a support member arranged for slidingly moving and fixedly secured relation to said first table, said second fine drive means including a movable portion connected to said second table.
