Patent ID: 7564693

Claim:
A power saving wake-up device for wireless mouse, the wireless mouse having a microprocessor with two wake-up pins, such that when the wireless mouse enters in a power saving mode to save power consumption and subsequently at least one wake-up pin used as a trigger source by the microprocessor is triggered, the wireless mouse in the power saving mode is waked up, the device comprising: first to fourth conductive plates, which form a quadrilateral with separated adjacent laterals, wherein the first and the third conductive plates are opposite to each other and both connected to a predetermined voltage level, and the second and the fourth conductive plates are opposite to each other and connected to the respective wake-up pins of the microprocessor; and a movable conductor, which is movably implemented in the quadrilateral and concurrently contacts with at most two adjacent conductive plates to thereby conduct the two conductive plates, such that when the wireless mouse is moved to cause the movable conductor to contact with the two conductive plates, the wake-up pin used as the trigger source by the microprocessor is triggered by the predetermined voltage level.
