Abstract: A component mounting device is configured to mount, on a substrate, an electronic component having a functional unit. The component mounting device includes a component supply mechanism, a recognition unit, a component mounting mechanism, and a holding position determination unit. The component supply mechanism supplies the electronic component. The recognition unit recognizes a position of the functional unit. The component mounting mechanism holds the electronic component supplied from the component supply mechanism and mounts the electronic component on the substrate. The holding position determination unit determines a holding position of the electronic component by the component mounting mechanism based on the position of the functional unit recognized by the recognition unit.

Abstract: A light emitting component mounting method for holding a light emitting component with a light emitter by a mounting head and mounting the light emitting component on a board is provided. The method includes energizing the light emitter to emit a light, measuring a luminance distribution of the light emitter and detecting a position of a luminance distribution center in the light emitter based on the measured luminance distribution.

Abstract: A light emitting component mounter includes a luminance distribution measurer, a head moving mechanism, and a component mounting processor. The luminance distribution measurer causes the light to emit a light and measures a luminance distribution of a light emitter and detects a position of a luminance distribution center in the light emitter based on the measured luminance distribution. The head moving mechanism moves a mounting head. The component mounting processor controls the head moving mechanism based on the position detected by the luminance distribution measure.

Abstract: A component mounter includes: a nozzle having a nozzle main body and a reflecting part provided behind the nozzle main body and reflecting light from the front, the nozzle main body including a greatest outer periphery section provided to a front section of the nozzle main body, and the greatest outer periphery section of an outer periphery of the nozzle main body provided in front on the reflecting part; a first illuminating unit provided in front of the reflecting part and illuminating the reflecting part from the front with light; and an imaging unit provided in front of the nozzle and capturing the greatest outer periphery section positioned in front of the nozzle main body, using the light from the first illuminating light and reflected off the reflecting part.
