Abstract

PURPOSE:To make a combination of two prisms unnecessary and to produce it at a low cost by forming a prism having shape obtained by combining two prisms possessing two reflective surfaces in one body with plastics in a prism where an inverted image changes to a normal image. CONSTITUTION:A prism body 8 has two reflective surfaces 9, 10 forming a right angle with each other, light transmissive surfaces 11 opposing to the reflective surface 9 with an angle of 45 deg., two reflective surfaces 12, 13 forming a right angle with each other and a light transmissive surface 14 opposing to a reflective surface 13 with an angle 45 deg.. Further reflective surfaces 10, 12 oppose to each other with an angle of 45 deg.. The prism body 8 is formed in a body entirely by light transmissive plastic. At the time a gate is formed on the surfaces 15-22 not employed optically and after the forming the reflective surfaces 9, 10, 12, 13 are polished.
