Electronic component mounting apparatus and electronic component mounting method

An electronic component mounting apparatus comprising:

• a component supply unit configured to supply an electronic component;
• a holding unit configured to hold the electronic component supplied from the component supply unit;
• a movement mechanism unit configured to move the holding unit;
• a component imaging unit configured to image the electronic component that is held by the holding unit;
• a control unit configured to control an imaging form of the electronic component by the component imaging unit;
• and
• a component recognition unit configured to recognize the electronic components based on an image that is imaged by the component imaging unit,
• wherein the component imaging unit has at least three area cameras that include two imaging elements, a visual field of a first imaging element and a visual field of a second imaging element in the two imaging elements included in each of the area cameras are different from each other, and the respective visual fields of the first imaging element and the second imaging element are common to each other regardless of the area cameras,
• the control unit sets the imaging form of the component imaging unit to a first imaging mode or a second imaging mode, depending on sizes of the electronic component that are held by the holding unit,
• when the imaging form is set to the first imaging mode, the component recognition unit recognizes a first electronic component held by the holding unit based on an image that is imaged by the first imaging element of each of the area cameras, and recognizes a second electronic component that is held together with the first electronic component by the holding unit based on an image that is imaged by the second imaging element of each of the area cameras, and
• when the imaging form is set to the second imaging mode, the component recognition unit recognizes the electronic component that are held by the holding unit, based on an image in which the image that is imaged by the first imaging element of each of the area cameras is combined with the image that is imaged by the second imaging element of each of the area cameras.
