Abstract
An optical mouse has a light emitting diode (LED) and a projecting lens located on a reflection path of the LED so as to project the light of the LED to the sensor. After the sensor picks up the signal from the LED, the signal is readily sent to the computer so as to simplify the structure and reduce the manufacturing cost of the optical mouse.
Claims19
A modulated optical mouse for a personal computer, the optical mouse comprising:
- a body having a predetermined space defined inside the body and having at least one lead securely provided inside the space and feet each electrically connected to one of the feet;
- at least one light emitting diode mounted inside the space to electrically connect with the lead, the light emitting diode being at a bottom of the body;
- and
- at least one sensor received in the space to electrically connect with the lead and to correspond to the reflective light from reflective surface (table surface) of light emitting diode.
