Zusammenfassung:	PURPOSE:To obtain the exchanger of laser masks for making which allows the automatic exchange of the masks for marking, can continuously execute marking operations on products varying in markings and have no errors in the masks for marking to be set. CONSTITUTION:A mask holder 1 having a sensor 11 which is disposed in correspondence to a laser beam source 8 and confirms the kinds of the masks to be set, a mask magazine 2 which houses the plural masks of different kinds, and a position detecting means 3 which detects the position of the mask to be set among the plural masks to be housed in this mask magazine 2 are provided. A moving means 4 which moves the mask magazine 2 up to the position where the mask to be set corresponds to the mask holder 1 by the detection signal of the position detecting means 3 and the mask to be set is mounted in the mask holder 1 and a mask clip 5 which returns and houses the set mask to the mask magazine 2 after the end of the marking are provided.
