Because the viewing angle of the camera is α>0, a side surface of the component is imaged. Based on the image data of the component, an index value specifying a size of the side surface of the component is calculated. Then, in a case in which the calculated index value matches a set value, it is determined that it is possible to hold the component. In other words, in a case in which there is a certain distance between multiple components, from imaging a side surface of the component, if an index value that specifies the size of the side surface of the component matches the set value, it is determined that it is possible to hold the component. ## Claims ### Claim 1 A component supply system for a component mounter, configured to supply components on a stage in a scattered state, the component supply system comprising: a holding tool configured to hold the component scattered on the stage, the holding tool attached to a frame section; an imaging device configured to image a target component from above that is a holding target of the holding tool, the imaging device including a camera; and an individual control device, including: a first calculating section, configured to calculate an index value that specifies a size of a side surface of the target component based on an image data of the target component captured by the imaging device; a second calculating section, configured to calculate a set value based on a position deviation of the target object calculated from multiple image data captured by the imaging device; a third calculating section, configured to calculate a shape of an upper surface of the target component based on the image data of the target component captured by the imaging device; a first determining section configured to determine whether the index value calculated by the first calculating section matches a set value; and a control section configured to control movement of the holding tool such that the target component held by the holding tool when the first determining section determines that the index value matches the set value; and an overall control device connected to the holding tool, the imaging device, and the individual control device. ### Claim 2 (depends on 1) The component supply system according to claim 1, wherein the set value is calculated based on a parallax that arises due to a deviation in a main light beam at a position of the target component on the stage and a light axis of the imaging device. ### Claim 3 (depends on 1) The component supply system according to claim 1, wherein the individual control device further includes a creation section configured to create multiple imaging data in accordance with multiple images captured by the imaging device of a given target component at different heights, and the second calculating section is configured to calculate the set value based on a position deviation of the target component from the multiple image data created by the creation section. ### Claim 4 (depends on 1) A component supply system according to claim 1, wherein the individual control device further includes a second determining section configured to determine whether the shape of the upper surface of the target component calculated by the third calculating section matches a preset shape, and the control section is configured to control movement of the holding tool when the first determining section determines that the index value matches the set value and the second determining section determines that the shape of the upper surface of the target component matches the preset shape.
