Abstract:
Device for exposing a peripheral area of a film circuit board by transporting the film circuit board in a transport direction and irradiating a resist on a peripheral area of the film circuit board with exposure light from a light irradiation means, the device comprising:means for determining the location of an edge of the film circuit board including an optical detector having a light projection section for transmitting a sensor light to the film circuit board and a light receiving part for receiving the sensor light from said light projection section; a controller for moving the film circuit board so that the resist on the peripheral area of the film circuit board is irradiated with exposure light, moving of the film circuit board being based upon data received from said means for determining; gas discharge means for discharging a gas on the peripheral area in a manner for flattening and maintaining said film circuit board planar, said gas being discharged on the peripheral area as the peripheral area is irradiated with exposure light; and a carrier for supporting the film circuit board, said carrier being composed of a material adapted to transmit sensor light to a bottom surface of the peripheral area.
