A mounting apparatus for collecting and mounting components, comprising: a tray member configured to move between an accommodating position and a collection position, the tray member having fiducial marks in multiple positions, the tray member being configured to accommodate components; a collection member for collecting components accommodated in the tray member ; an imaging section configured to capture an image of the fiducial marks ; and a control unit configured to execute a first mode of, at least when the tray member is first moved to the collection position, controlling the imaging section to capture an image of the fiducial marks and obtaining a correction value by which the collection position of a component is corrected based on the positions of the fiducial marks in the captured image, characterized in that the control unit is further configured to execute a second mode of, when the tray member is moved to the collection position, controlling the imaging section to capture an image of the fiducial marks and obtaining a correction value by which the collection position of a component is corrected based on the positions of the fiducial marks in the captured image, the correction value of the second mode being obtained more frequently than in the first mode, wherein the control unit is configured to shift the mode from the second mode to the first mode when the correction values obtained in the second mode are continuously within a predetermined permissible range, and/or the control unit is configured to shift the mode from the first mode to the second mode when the control unit obtains information on a positional deviation of a component collected by the collection member and the positional deviation is outside of a predetermined permissible range, and/or the control unit is configured to execute the first mode or the second mode based on a setting made by an operator. a tray member configured to move between an accommodating position and a collection position, the tray member having fiducial marks in multiple positions, the tray member being configured to accommodate components; a collection member for collecting components accommodated in the tray member ; an imaging section configured to capture an image of the fiducial marks ; and a control unit configured to execute a first mode of, at least when the tray member is first moved to the collection position, controlling the imaging section to capture an image of the fiducial marks and obtaining a correction value by which the collection position of a component is corrected based on the positions of the fiducial marks in the captured image, characterized in that the control unit is further configured to execute a second mode of, when the tray member is moved to the collection position, controlling the imaging section to capture an image of the fiducial marks and obtaining a correction value by which the collection position of a component is corrected based on the positions of the fiducial marks in the captured image, the correction value of the second mode being obtained more frequently than in the first mode, wherein the control unit is configured to shift the mode from the second mode to the first mode when the correction values obtained in the second mode are continuously within a predetermined permissible range, and/or the control unit is configured to shift the mode from the first mode to the second mode when the control unit obtains information on a positional deviation of a component collected by the collection member and the positional deviation is outside of a predetermined permissible range, and/or the control unit is configured to execute the first mode or the second mode based on a setting made by an operator. <EOS>
