Mounting apparatus, recognition device and recognition method for electronic component

A method of recognizing an electronic component in which image recognition of an electronic component is conducted by illuminating and reading an image of the electronic component held by a nozzle disposed on a mounting head by lighting means and by an image pickup device, said method comprising the steps of:

• a) illuminating the electronic component held by said nozzle disposed on the mounting head;
• and
• b) capturing an image of the electronic component by the image pickup device and recognizing the image of the electronic component;
• c) switching between reflection illumination for acquiring an image with the electronic component appearing as a light image and transillumination illumination for acquiring an image with the electronic component appearing as a dark image, by selecting the wavelength of light projected to:
• i) a first light reflector disposed on the mounting head and including an illuminating body which illuminates by absorbing light from a first light source, and a selectively transmitting body disposed on the illuminating body, which transmits light from said first light source and absorbs light from a second light source;
• and
• ii) a second light reflector disposed on said nozzle and including a transparent body which transmits light, an illuminating body disposed on the transparent body, which illuminates by absorbing light from said first light source, and a selectively transmitting body disposed on the illuminating body, which transmits light from said first light source and absorbs light from said second light source.
