Abstract
A transfer pathway of a mounting headin a component-mounting round during which the mounting headmoves back and forth between a component feeding unitand a substrate conveyance mechanismis derived by a transfer pathway calculation unitfor each component-mounting round from mounting program data. A focusing processing unitcontrols an optical system focusing mechanism, thereby matching a focusing point of a line sensor cameraachieved during imaging operation to the transfer pathway of the mounting headbased on data pertaining to the derived transfer pathway. Further, an optical system zooming mechanismadjusts an imaging range according to the focusing point. Accordingly, even when a long substrateis taken as an object, it is possible to detect with high precision whether or not a component exists on the pickup nozzleof the mounting head
