PROBLEM TO BE SOLVED: To increase the moving amount of an X-Y table by performing the movement of the X-Y table to a position indicated in the next step of a mounting program when mounting operation is not performed by using a period which is capable of the X-Y table movement wherein mounting is not performed and the next period cable of X-Y table movement. SOLUTION: When mounting is not performed, the operation of an X-Y table is unnecessary during a mounting period, so that the mounting operation of the X-Y table in the next step of a mounting program is performed. First, the amount L1 that the X-Y table can move in the period capable of movement of the X-Y table is calculated from the operation speed of a rotating table and that of the X-Y table. Secondly, the amount L1 is compared with the amount L of movement of the mounting program, and the contents of L are transferred to L2 in the case of L<=L1. Movement of the amount L2 is performed during the period which is capable of X-Y table movement, and processing is ended. As a result, the moving amount of the X-Y table can be increased. |
