The SLA 4 is positioned to a reference face 3f at a left side 3g of the SLA holder 3. A projection 3b is formed on a lower part of the left side 3g of the SLA holder 3. A lower groove 2b is formed on a bottom face of the base section 2. When the SLA holder 3 is loaded to the base section 2, the projection 3b is inserted to the lower groove 2b so that the SLA holder 3 is positioned to the base section 2.</p> |
