Zusammenfassung:	PURPOSE:To uniform pressure applied to a core and to reduce the deformation and destruction of a mold by forming at least either of a light incidence part and a light projection part into a circular projecting part. CONSTITUTION:A pentagonal prsim 1 has the circular projecting part as a projection surface 2 for light. This circular projecting part may be provided with the incidence part for light and both incidence and projection surfaces may be formed in circular projecting parts. Thus, the circular projecting part is made into a pressure part of the core, which is made circular to uniform the pressure applied to the core, reducing the deformation and destruction of the mold.
