PROBLEM TO BE SOLVED: To improve mounting efficiency while taking into account a number N of times of stopping a substrate and substrate stop positions Xto Xso as to reduce a total tac time T.SOLUTION: The number N of times of stopping a substrate is successively computed (steps S11, S18 in Figure 6). Based on a mounting range in which an electronic component Ct can be mounted, a head unit 41 determines a stop position of a printed substrate W for each number N of times of stopping the substrate (sub routine S12 in Figure 7). For each computed number N of times of stopping the substrate, at each of the stop positions of the printed substrate W relating to the number N of times of stopping the substrate, a total tact time Trequired in the case where the electronic component Ct is mounted on the substrate W is computed (steps S14 to S16 in Figure 6). When a total tact time Tbased on a number N-1 of times of stopping the substrate just before increment is shorter, the number N of times of stopping the substrate just before increment is determined as an optimal number Nof times of stopping the substrate. |
