PROBLEM TO BE SOLVED: To provide an NC circular table and an NC circular table system improved in practical usability and workability to unnecessitate return-to-origin work concerning the encoder of an absolute system using a backup battery. ;SOLUTION: Concerning the NC circular table which is used for an NC working device having an NC controller 1 and performs position detection with an encoder 3 of the absolute system, a backup battery 5 of the encoder 3 is arranged in a main body 4 of NC circular table. Since data such as original position or current position in the encoder 3 are held by the backup battery 5 arranged in the main body 4 of NC circular table, even when the main body 4 of NC circular table and the NC controller 1 are disconnected and connected again, it is not necessary to perform return-to-origin work and a work can be worked again by the main body 4 of NC circular table.;COPYRIGHT: (C)2000,JPO
