| 20110018800 | OPTICAL POINTING APPARATUS AND PORTABLE ELECTRONIC APPARATUS WITH THE SAME - An optical pointing device and a portable electronic device having the same, in which external noise light and/or noise light due to diffused reflection or the like is prevented from being introduced into an optical sensor enhancing precision of operation and providing a housing with improved structure. The device includes an infrared source; a cover having a cover plate transmitting infrared rays from the IR source for reaching a subject out of the cover plate and a cover frame that supports the cover plate; an optical unit in the cover and on which the infrared ray reflected from the subject is incident; and an optical sensor sensing the infrared ray incident thereon from the optical unit; the cover plate has a base coupled to the cover frame, and an IR band-pass filter layer provided on one side of the base. | 01-27-2011 |
| 20100194712 | OPTICAL POINTING DEVICE AND PORTABLE ELECTRONIC DEVICE HAVING THE SAME - Disclosed herein is an optical pointing device as a user interface for electronic devices such as communication terminals and the like. The optical pointing device includes a light receiving part, an optical unit transferring light to the light receiving part and including a reflection part disposed in an optical path, a frame body integrally formed with the reflection part to support the reflection part, a cover covering the frame body and having an interface surface, and a light source illuminating the cover. The optical pointing device reduces the number of components and permits convenient and easy assembly, thereby significantly improving productivity while reducing assembly defect. | 08-05-2010 |
| 20090184852 | Optical joystick and portable electronic device having the same - An optical joystick and portable electronic device having the same are disclosed, by which malfunctions of the optical joystick due to sunlight or external illumination light are prevented or minimized. Therefore, precision of the optical joystick can be enhanced. The optical joystick according to the present invention includes an infrared light source, a cover part having a contacting surface for a contact by a subject, a light-receiving part detecting the infrared ray, and an optical member provided on an light path of the infrared ray traveling from the cover part toward the light-receiving part, wherein the cover part comprises a cover base and an infrared ray pass layer blocking out external noisy light on a predetermined band and passing substantially a wavelength band of infrared rays. | 07-23-2009 |
