  • Publication number: 20100001956
    Abstract: Provided is a handheld terminal. The handheld terminal includes a case having a through-hole formed at one side thereof; and an optical module constituted by a circuit board in which a light source for irradiating light and a sensor for receiving the light are installed, a lens disposed at one side of the circuit board and inserted into the through-hole, and a support bracket disposed at the other side of the circuit board. Therefore, it is possible to uniformly maintain the height of the sensor for receiving light based on the thickness of the lens to maintain a certain depth of focus.

  • Patent number: 7609250
    Abstract: Provided are an optical module and an input apparatus having the same. The input apparatus includes the optical module having a circuit board provided with a light source and a sensor installed therein, a lens disposed at one side of the circuit board, and a support bracket disposed at the other side of the circuit board; and a main body having a through-hole at its one side and into which the lens of the optical module is inserted. Therefore, it is possible to uniformly maintain the height of the sensor for receiving light based on the thickness of the lens to maintain a certain depth of focus.

  • Publication number: 20070008284
    Abstract: Provided is a wired or wireless mouse, one of peripheral devices of a computer. The mouse is capable of installing a built-in microphone in the mouse without a design change of a mouse surface, outputting a voice signal from the microphone to a soundcard of a computer through a separate output line different from an output line of the mouse, removing noise generated when a voice signal is output during operation of the mouse, transmitting the voice signal to the computer through the microphone even while an application program is executed in the computer through the mouse, and improving sensitivity of the voice signal input into the computer.
