Abstract
An illuminating apparatus includes a columnar light guide, a board having a light source fastened on one surface thereof, and a holder. The holder is formed with a through-hole into which an end of the light guide in the columnar center axis direction is fitted to hold the light guide, and a catch that catches and holds the board with the light source facing the end surface of the light guide in the columnar center axis direction in the through-hole.
Claims4
An illuminating apparatus comprising:
- a casing;
- a columnar light guide retained in the casing;
- a board including a light source fastened on one surface thereof;
- and
- a holder having,
- a through-hole into which an end of the light guide in a columnar center axis direction is fitted to hold the light guide, said light source facing an end face of the light guide in the columnar center axis direction, the through-hole optically passing all the way through a first surface of the holder and a second surface opposite to the first surface of the holder, the through-hole transmitting light from the light source to the light guide,
- a protruding pin extending from the holder along the columnar center axis direction and that is fitted into a hole of the board, including the light source and
- a fitting claw that holds the board along a short direction of the casing.
