Problems solved by technology

When the user wants to use the mouse, he will push the mouse with his hand, causing the mouse to move, causing the host to wake up. As far as the process of the wake-up function is concerned, the human body will first touch the mouse, and then move the mouse to generate X and Y axis movement
The traditional optical mouse only has a wake-up function, and cannot have a two-way switching mode function. In the normal operation mode, when the hand leaves the mouse, it cannot immediately enter the power-saving mode from the normal operation mode, and it is not easy to support the wake-up function in the power-saving mode. Disadvantages of battery saving

Embodiment Construction

[0025] figure 1 It is a schematic diagram of the optical mouse 10 of the present invention, which has normal operation and power-saving mode, buttons 12 and 14 are arranged on the casing, the mechanism wheel 16 is between the buttons 12 and 14, and the capacitive touch panel 18 is located between the optical buttons 12 and 14. on the hand-held part 20 of the mouse 10 . The capacitive touch panel 18 is a switching mode device of the optical mouse 10. When the user does not use the mouse 10, the hand leaves the capacitive touch panel 18, causing the capacitance value of the capacitive touch panel 18 to change, so that the mouse 10 changes from normal to normal. The operation mode enters the power-saving mode. When the user wants to move the mouse 10, the hand touches the capacitive touch panel 18, causing the capacitance value of the capacitive touch panel 18 to change, so that the mouse 10 returns to the normal operation mode from the power-saving mode The power saving mode of...

Abstract

A mode switching device for an optical mouse includes a capacitive touch panel embedded in the mouse casing and a microprocessor connected to the capacitive touch panel. When a hand touches or leaves the touch panel, a The capacitance change is received by the microprocessor to switch the mouse to different modes.

Description

technical field [0001] The invention relates to an optical mouse, in particular to an optical mouse mode switching device using a capacitive touch panel. Background technique [0002] Optical mouse uses light-emitting diode (LED) to provide light source, but the light-emitting diode consumes a lot of power. In order to save the power consumption of the mouse, the operation mode of the mouse is divided into normal operation and power-saving mode. Automatically enter power-saving mode from normal operation mode to reduce the frequency of optical mouse detection movement and reduce the number of detection times. After the mouse in the power-saving mode is triggered by the wake-up function, it returns to the normal operation mode from the power-saving mode. [0003] The traditional wake-up function achieves the purpose of waking up the mouse by triggering an input key. The improved wake-up function utilizes the light reflected from the operating surface of the mouse to be dete...
