Abstract
In a palette movement in which a palette (24) which holds a tray (6) whose components are used up is moved from a palette carrying part (27) where the palette (24) was carried for the exchange with a new tray (6) to a palette accommodating part (23), the accommodating address of the return destination is specified based on a readout result of a palette identification mark of a palette information readout sensor (32) and palette accommodating data which are stored in advance. Therefore, even if the components in two or more palettes (24) are used up in the same period, the palettes (24) can be returned to the palette accommodating parts (23) corresponding to the specified accommodating addresses of the return destinations.
