PURPOSE:To easily change connections of a line by providing a fixed terminal part which enables an insertion terminal part which has a lens and a prism for bending light at right angles to be interposed between two opposite lenses. CONSTITUTION:The insertion terminal part 2 which has the lens 3 and the prism 4 for bending the light passing through the lens 3 by 90 deg. and the fixed terminal part 1 which inserts the two opposite lenses 3a and 3b and insertion terminal par 2 are provided. When the insertion terminal part 1 is interposed between the two opposite lenses 3a and 3b from the insertion part 15 of the fixed terminal part 15, a light beam path which passes through the lens 3 of the insertion terminal part 2 is formed at right angles to a light beam path passing through the two lenses 3a and 3b. Consequently, the light beam path 13 which is connected halfway freely can easily be formed be using plural fixed terminal parts 1. |
