Abstract
A prism/lens array () in the present invention is a grass prism having an approximately 45 degrees tapered part. A plurality of lenses () are provided side by side on the front surface of the prism/lens array (). A pair of protrusions () are formed on both sides of lenses () on the surface on which the lenses () are provided. The protrusions () are formed in the top-bottom direction of the prism/lens array () and roughly V-shaped cross sections. Grooves () are provided in an inside surface of a prism-securing part (), in areas corresponding to the protrusions (). The grooves () are shaped such that the protrusions () can fit into the grooves; for example, the grooves could have roughly V-shaped cross sections.
