Rotary input apparatus
First Claim
1. A rotary input apparatus, comprising:
- a wheel having an insertion hole in a center thereof and having a wheel light transmission portion formed along an edge thereof;
a center key inserted into the insertion hole and having a center light transmission portion formed along an edge thereof;
a magnet joined to a surface of the wheel to co-operate with the wheel and magnetized to have alternating N- and S-poles;
a detection element positioned to face the magnet and configured to detect a rotation of the magnet;
a light emission part configured to diffuse light to the exterior through the wheel and the center key;
a printed circuit board having the detection element and the light emission part mounted thereon;
a base having the printed circuit board secured to a surface thereof; and
a holder joined to the base and interposed between the wheel and the base to rotatably support the wheel.

Abstract
A rotary input apparatus is disclosed. With a rotary input apparatus comprising a wheel in the center of which is formed an insertion hole and along the edge of which is formed in a wheel light transmission portion; a center key, inserted into the insertion hole, along the edge of which is formed a center light transmission portion; a magnet, joined to a surface of the wheel to co-operate with the wheel, which is magnetized to have alternating N- and S-poles; a detection element, positioned facing the magnet, which detects the rotation of the magnet; a light emission part, which diffuses light to the exterior through the wheel and the center key; a printed circuit board, on which are mounted the detection element and the light emission part; a base having the printed circuit board secured to its surface; and a holder joined to the base and interposed between the wheel and the base to rotatably support the wheel, the wheel and center key are illuminated by a light emission part, to provide improved convenience and greater aesthetic value.
