Claim One:
1. A component placing head having a plurality of component holding members for releasably holding components which members are arranged in a row, and being capable of placing on a circuit board the plurality of components held by the component holding members, the component placing head comprising: a first component image-pickup unit capable of capturing images of the components held by the component holding members from a direction along central axes of the component holding members; a second component image-pickup unit capable of capturing images of the components held by the component holding members from a direction generally orthogonal to the central axes of the component holding members and to a direction of the arrangement of the component holding members; supporting members for supporting the first component image-pickup unit and the second component image-pickup unit so as to allow movement thereof in the direction of the arrangement of the component holding members; a moving device for moving the first component image-pickup unit and the second component image-pickup unit in the direction of the arrangement of the component holding members between the component holding members arranged at both ends of the row; and a control unit that causes the first component image-pickup unit and the second component image-pickup unit to sequentially capture the images of the components held by the component holding members while moving the first component image-pickup unit and the second component image-pickup unit by the moving device in the direction of the arrangement of the component holding members and that is capable of recognizing holding postures of the components on the component holding members on basis of the images of the components captured by the first component image-pickup unit and the images of the components captured by the second component image-pickup unit, wherein the components can be placed on the circuit board on basis of the holding postures of the components recognized by the control unit.
