Abstract
PURPOSE: To control the copying of the groove on the rear side easily and adequately by providing a pair of interposing materials consisting of materials differing from base metals and of mutually different materials to the groove on the rear side of the base metals and detecting the intrinsic X-rays generating from the interposing materials.
CONSTITUTION: A pair of interposing materials 5, 6 are set near the groove 2b on the rear side of the groove 2 of base metals 1, and respectively different materials are used for these three. An X-ray detector 7 is disposed on the rear side of the base metals 1, and is so set that the X-rays detected by a slit 8 are sligned in one direction and are conducted to a crystal 9, and that the X-rays genetrating from the material 5 enters a counter tube 10 and the X-rays from the material 6 enters a counter tube 11. When an electron beam A is irradiated from an electron gun 4, it is irradiated to either of the materials 5, 6 when it is not correctly irradiated to the groove 2a, then the X-rays intrinsic to the materials 5, 6 are genetrated and are detected by either of the tubes 10, 11. According to the deflection of the beam A, bases 3 are operated to move the base metals 1, whereby the copying control is accomplished.
