Abstract: A component mounter comprises first and second imaging systems, and a mounting head configured to hold a component by a nozzle. The first and second imaging systems irradiate light of first and second wavelengths, respectively, toward a working position to illuminate the nozzle located at the working position. The nozzle is imaged by the first and second imaging systems, respectively, that receive light having the first and second wavelengths, respectively, transmitted through first and second optical filters, respectively, after being irradiated on the working position. The first and second optical filters thus prevent light having wavelengths different from the first and second wavelengths from reaching the first and second imaging devices. Therefore, the nozzle can be imaged more precisely, since the influence of light different from the illumination light having the first and second wavelengths is suppressed by the first and second optical filters.

Abstract: A substrate working device includes a working unit that performs work on a substrate on which a component is mounted, an imager capable of imaging a correction mark for position correction, and a mark projector that projects the correction mark. The correction mark includes a first correction mark and a second correction mark. The mark projector projects the first correction mark to a first height and projects the second correction mark to a second height.

Abstract: A plurality of nozzles are arranged at intervals of a center-to-center distance along a circumferential orbit around the predetermined rotation axis integrally. The nozzle that is positioned at the working position is changed by rotating the plurality of nozzles around the predetermined rotation axis. At that time, regardless of the manner in which the nozzle positioned at the working position is changed, the nozzle approaching the working position, and the nozzle moving away from the working position, move within an imaging target range having a width smaller than twice the center-to-center distance with the working position as the center along the circumferential orbit. Then, a camera images the nozzle which is moving within the imaging target range. Thus, it is not necessary to temporarily stop the nozzle for imaging, and as a result, imaging of the nozzles is performed efficiently.

Abstract: A component mounter comprises a mounting head that holds a plurality of nozzles. Two imaging positions are provided for the circumferential orbit along which the nozzles of the mounting head are arranged. While the nozzles are rotated continuously about the rotation axis, an operation of imaging the nozzles located at the imaging positions is performed for each of the imaging positions. Therefore, in a period when the nozzles rotate by an angle not larger than a predetermined angle around the rotation axis formed by the interval between the two imaging positions adjacent to each other along the circumferential orbit, imaging of the nozzles can be completed by locating each of the nozzles at one of the two imaging positions. As a result, it becomes possible to image the plurality of nozzles of the mounting head efficiently.
