PURPOSE: An ultra slim optical joystick is provided to produce a prism integrally with a holder, thereby simplifying assembly components. CONSTITUTION: A light source(20) is mounted on a main board(64) through an SMT(Surface Mount Technology) process. A housing(30) is illuminated with an infrared light source. A subject is touched by the housing. A holder(40) includes a pair of reflecting members(42) to reflect light of the light source. An imaging lens(50) is between the reflecting members. A mask(55) prevents other lights among lights passing through the imaging lens. A light receiving unit(60) detects light passing through the mask. |
