PURPOSE:To provide the two-shaft synchronous driving device which can drive two shafts synchronously with high accuracy by composing a correcting circuit of an integrator, a differentiator, and a fuzzy controller and performing PID arithmetic based upon a fuzzy rule. CONSTITUTION:The correcting circuit 31 consists of a subtracter 54 which subtracts a deviation signal B from a deviation counter 24 from a deviation signal A from a deviation counter 23, the integrator 52 and differentiator 53 which integrate and differentiate the result (A-B), and the fuzzy inference part 51 which inputs the (A-B) and integrated and differentiated values and outputs correction signals K1 and K2 corresponding to Y-axial motors 3 and 4. Driving means 27 and 28 for the motors are controlled according to the signals generated by adding the deviation signals A and B and correction signals K1 and K2 together. Therefore, the motor for one shaft is applied with a driving current which is corrected by more than the quantity based upon the deviation signals and the motor for the other shaft is applied with a driving current which is corrected by more than the quantity based upon the deviation signals to speedily secure the synchronous driving state.
