LASER TRANSFER DEVICE

PROBLEM TO BE SOLVED: To provide a laser transfer device capable of enhancing precision of matching between the light convergence height of a laser beam and the height of a transfer material thin film on the reverse surface of a transfer plate when introducing an automatic focusing technique. SOLUTION: The laser transfer device is equipped with a light convergence point height positioning means of expecting it to be judged that an electronic camera is put in focus while causing the laser light convergence point height to approach the transfer plate supported by a transfer head through a light convergence point height adjusting mechanism, and stopping the approaching operation of the laser light convergence point when obtaining the judgment indicating that the electronic camera is put in focus to position a laser light convergence point on the transfer thin film on the reverse surface of the transfer plate, and it is judged whether the electronic camera is put in focus based upon an image of a focusing mark displayed on the transfer plate so as to clearly be discriminated from the transfer material thin film.
