ULTRA SLIM OPTICAL JOYSTICK

摘要

PURPOSE: An ultra slim optical joystick is provided to enable mass production and prevent the occurrence of defective products by simplifying the fabrication process of a housing. CONSTITUTION: A housing(60) is illuminated by a light source which emits an infrared ray and contacts a subject. A holder(70) is coupled to the housing to be prepared in an acceptance space. An imaging member is installed at a holder and collects the light reflected from the subject. An image sensor(90) detects the light collected through the imaging member, and an external light shielding material is printed on the portion except some portion on the upper plane of the housing through which the infrared ray is transmitted. An anti-scratch coating material is coated on the external light shielding material.
