Problems solved by technology

[0012] However, this conventional laser navigation module does not have a separate illuminator and thus is inconvenient for users to use in dark locations
Although an illuminator can be separately equipped outside the laser navigation module, the separate illuminator cannot be easily installed in the laser navigation module because the laser navigation module is too small
In addition, even if the illuminator can be installed in the laser navigation module, it is still difficult to manufacture a laser navigation module that can uniformly transmit the light emitted by the illuminator to the outside of the laser navigation module.

Abstract

Disclosed herein is a laser navigation module. A light source emits a laser beam. A housing includes an IR window and a transparent or semitransparent part. The IR window transmits or reflects the laser beam emitted from the light source, and also interrupts transmission of external visible rays. The transparent or semitransparent part allows light emitted in the housing to be transmitted out of the housing. An illuminator is installed in the housing. A light diffusion unit transmits the light emitted from the illuminator to the housing. The light diffusion unit has a re-reflective layer on a portion thereof facing the illuminator.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2010-0093355, filed Sep. 27, 2010, entitled "Laser Navigation Module," the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a laser navigation module. Background technique [0004] Typically, a personal mobile communication terminal, such as a cellular phone or a smart phone, includes a user interface using keys. The keys include input buttons related to numbers, letters and directions. [0005] Recently, the commercialization of wireless Internet services such as WIBRO (Wireless Broadband) service has led to the development of personal mobile communication terminals using a windows operating system supporting GUI (Graphical User Interface). [0006] This means that an operating system supporting a GUI is used as a user interface of a personal mobile communication terminal. Therefor...
