A transfer pathway of a mounting head 10 in a component-mounting round during which the mounting head 10 moves back and forth between a component feeding unit 4 and a substrate conveyance mechanism 2 is derived by a transfer pathway calculation unit 25 for each component-mounting round from mounting program data 21a. The base includes a plurality of upstanding ridges, with an opening being defined between each of the ridges. Extenders can be modeled so that, for example a particular bundle requires a handler for a particular configuration manifest entry; while a particular module provides handling of that manifest entry. The determination unit configures to determine a threshold value for binarizing each of the pixels by performing an inversion correction with respect to the temporary threshold value which is selected in the selection unit, on the basis of the gray level conversion parameter which is calculated in the parameter calculation unit. 92 gcm3, and the densities of the first and second polymers differ by at least 1%.
