Abstract

PURPOSE:To make speeding up of engravement of lines easier and to shorten manufacturing time of a diffraction grating, by making a grating base plate or a tool moving stage to be a double structure, making such a constitution that gives continuous forwarding to the first part, and positional deviation against the first part to the second part by means of expansion and contraction of a piezoelectric element and controlling the amount of expansion and contraction of the piezoelectric element in such a way that the second part is apparently stopped when grooves are engraved. CONSTITUTION:A piezoelectric element 6 is fixed in such a way that it is held from both sides between a metal fitting 7 fixed on a moving stage 5 for a diffraction grating and a metal fitting 8 fixed on a base plate stage 4, and expanded and contracted in the groove distance forwarding direction. When no expansion and contraction exists, the base plate stage 4 integrally moves with the moving stage 5 for the diffraction grating. When the piezoelectric element 6 expands and contracts, the relative position of the base plate stage 4 to the moving stage 5 for the diffraction grating changes, and the position of the base plate stage 4 is given as the sum of a continuous forwarding by a forwarding screw 10 and a discontinuous forwarding accompanied with the expansion and contraction of the piezoelectric element 6. Therefore, if the continuous forwarding by the forwarding screw is compensated with the contraction of the piezoelectric element, the position of the base plate stage changes step by step and as the result, a successive forwarding for the groove distance is given to the base plate 3 for diffraction grating.
