Abstract
In an image recognition method, the image of a cream solderprinted on a rectangular electrodehaving a solder leveler formed is picked up and recognized to identify the cream solder. An illuminating unit having white light source partsW arranged in the radial oblique directions of 45° is used to apply white color illumination lights from a light applying direction in which an angle of θ1 formed by the light applying direction and a horizontal plane in a vertical plane is 45° or smaller and from a light applying direction in which an angle of θ3 formed by the light applying direction and the boundary of the electrodein a horizontal plane is 75° or smaller. Thus, regularly reflected lights from a solder leveler forming surfacewith a glossiness are not received by an upper camera to identify a solder surfaceand the solder leveler forming surfacewith good accuracy.
