Abstract

The present invention discloses an optical pointing apparatus and a portable electronic apparatus with the same. The optical pointing apparatus has improved accuracy by preventing the inflow of external light and / or unnecessary light caused by scattered reflection into an optical sensor. In addition, the structure of the cover that forms a housing is improved in the optical pointing apparatus. The pointing apparatus comprises an infrared-ray source (IR source) that emits an infrared ray, a cover that includes a cover plate and a cover frame, an optical unit that is installed inside of the cover, an optical sensor that senses the infrared ray transmitted through the optical unit. The infrared ray emitted from the infrared-ray source penetrates through the cover plate to reach a target, and the cover frame supports the cover plate by being coupled with the cover plate. The infrared ray reflected from the target outside the cover plate is incident onto the optical unit. The cover plate includes: a base that is fixed to the cover frame, and a thin infrared-ray (IR) band-pass filter layer that is formed at one side of the base.

Description

technical field [0001] The present invention relates to an optical pointing device and a portable electronic device with the optical pointing device, in particular to an optical pointing device that can be used for a user interface of an electronic device such as a mobile terminal, and a portable electronic device with the optical pointing device. Background technique [0002] Generally, electronic devices such as mobile terminals, personal digital assistants (PDAs), etc. use keyboard-based user interfaces. [0003] More specifically, a general portable electronic device includes a keypad formed with a plurality of buttons for inputting numbers, characters or symbols, and thus the user can input specific data such as numbers, words, etc. to the portable electronic device or select a menu by pressing a button of the keypad. . [0004] Furthermore, the portable electronic device is provided with a display unit so that data input via the keypad and / or information corresponding...
