Description of the Invention: [Technical Field] The present invention relates to a power saving device, and more particularly to a power saving device suitable for a wireless mouse. [Prior Art] The general wireless mouse uses the internal battery to provide the power required for its operation. Since the battery power is extremely limited, the wireless mouse has the function of power saving mode to provide more power saving effect. . As shown in Figure 当, when the wireless mouse does not move for a while, the microprocessor 9 will go to sleep and turn off most of the power to bring the wireless mouse into power save mode. Then, to determine whether the wireless mouse is moved again, the microprocessor 90 in the wireless mouse is waking up intermittently to drive the illumination unit 9 i to 15 92 (=D) to emit - the light source 'light source is reflected in the light sensing On the unit %, the light sensing unit 93 converts the light number into an electronic signal to determine whether the mouse moves according to the movement of the mouse, and wakes up the wireless mouse; otherwise, it enters the power saving mode. (4) The method is to reduce the loss of the electric society, and the wake-up action of stretching is not really a complete power-saving mode. In addition, 'Women Huamin Shili Announcement f 56232峨"; it is mainly when the wireless mouse is not used = the bean production:: method causes the wireless mouse internal vibration sensor short circuit, signaling to wake up the wireless slip The mouse, which in turn improves the intermittent measurement, the wireless mouse can turn off all power-consuming power, and only with the micro-power supply. However, as shown in Figure 2, when the wireless mouse is idle, the position of the water sensor π 处 尸 丄 丄 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 并不 位置Xianmiao Temple „ ^ φ ^ -V * . Induction of the open circuit and the wireless mouse does not consume electricity when entering the electric mode, but also ^ ^ ^, this will cause the vibration induction in the position B 'short circuit and make the wireless slip When the mouse enters the electric power mode, it still consumes power, which results in more power consumption than in use. ^ Cry 廿 &, also +, thus knowing 'Because this vibration induces σ. Asia cannot be guaranteed at all times For an open circuit # & (4) state, therefore, when the wireless mouse is not used for a period of time, such I line ^ φ ^ . ^ D„ ... line, enter a power saving mode, and the vibration induced state is just a short circuit The makeup can be 丨4_ 峪 state, the power will be consumed through this short circuit, and the wireless mouse can not achieve the purpose of power saving. 10 It can be seen that the power-saving design of the conventional wireless mouse still has many defects and needs to be improved. SUMMARY OF THE INVENTION The main object of the present invention is to provide a wireless mouse power saving device '俾 enables the wireless mouse to be unused - to actually enter the power saving mode after a period of time' without intermittent testing of the wireless Whether the mouse moves to save maximum power consumption. Another object of the present invention is to provide a wireless mouse power saving device that ensures that the wireless mouse's power saving device can operate effectively. According to a feature of the present invention, a wireless mouse power saving device is provided. The wireless mouse has a microprocessor, the microprocessor has two wake-up pins, and the wireless mouse can enter a power saving mode to save The power is consumed, and the microprocessor can have at least one wake-up pin as a trigger source, so that when it is triggered, the wireless mouse will be woken up in the power saving mode, the power saving device package 20 t-fourth The conductive plate unit is formed into a quadrilateral shape, and the two adjacent portions are not in contact, and the first and third conductive plate units are oppositely disposed, and both are connected to a preset potential, and the second and fourth conductive plate units are opposite to each other. The device is respectively connected to the second wake-up pin of the microprocessor; and a mobile = body unit is movably disposed within the quadrilateral, and can be connected to the adjacent conductive plate unit at most And the two conductive plate units are turned on, and when the wireless mouse is moved, the moving conductor unit can contact two adjacent four conductive plate units, and the wake-up pin as a trigger source is triggered by the preset potential. [Embodiment] The present invention relates to a power saving device for a wireless mouse. First, please refer to FIG. 3 for a schematic diagram of an embodiment of the present invention. In Fig. 3, the wireless mouse set is provided with a microprocessor 3 and a power saving device 4. Microprocessor 3 has two wake-up pins 15, 31. The power saving device 4 has first to fourth conductive plate units 41, 42, 43, 44, and a moving conductor unit 45. The first to fourth conductive plate units 41, 42, 43, 44 form a quadrilateral, and the two adjacent sides are not in contact with each other, wherein the first and third conductive plate units 41, 43 are oppositely disposed, and are connected to For example, the preset potential of the ground potential, the second and fourth conductive plate units 2 〇 42, 44 are also oppositely disposed 'and connected to the second wake-up pins 31, 32 of the microprocessor 3, respectively. The moving conductor unit 45 is movably disposed within the quadrilateral and can simultaneously contact at least two adjacent conductive plate units 41, 42, 43, 44 to turn on the two conductive plate units 41, 42, 43, 44. In the present embodiment, the moving conductor unit 45 can be a metal ball. The quadrilateral of the first component is a square 5 10 . FIG. 4 is a flow chart showing the operation of the power saving device of the wireless mouse of the embodiment, and referring to FIG. 3 , when the wireless mouse is idle for a period of time, Before entering the power saving mode, it is first determined whether the wake-up pins 31, 32 are connected to the ground potential (step S〇5). If one of the wake-up pins is connected to the ground potential, the microprocessor 3 sets another wake-up connection (four) as the trigger source (step S1?, if the two wake-up pins 31, 32 are not connected to the ground potential, then micro The processor 3 sets the two wake-up pins 31, 32 as trigger sources (step si5), after which the mouse enters the power-saving mode (step coffee). When the user moves the pay-line mouse again, the transfer body unit 45 will be free (four) or rolling due to force, and will touch adjacent two conductive plate units 41, 42, 43, 44, which will connect at least one wake-up pin 31, 32 as a trigger source to the preset power That is, since the wake-up pins 31, 32 are triggered by the preset 15 bits (step S25), the mouse is woken up from the power saving mode (step S30). 20 to the fourth conductive plate units 41, 42, 43 In this way, an embodiment of the present invention can provide a wireless mouse power saving device, which can enable the wireless mouse to enter the power saving mode after being used for a period of time without intermittent testing of the wireless mouse. Whether it is moving, thus saving the maximum power consumption. In addition, because the wireless mouse is idle Regardless of whether the moving conductor unit 45 contacts the conductive plate units 41, 42, 43, 44, no power consumption is caused, so that the power saving device of the wireless mouse can be effectively operated. In the foregoing embodiment of the present invention, In order to simplify the description, the preset potential is explained by the ground potential (GND). Therefore, the internal wake-up pin of the microprocessor is preset to a high voltage. Of course, the external 8 1324316 resistor can be added externally (pull-high). Resistor) to ensure that the voltage level of the wake-up pin is kept at a high voltage. Similarly, the preset potential can also be set to - system positive voltage (VCC), therefore, the microprocessor wake-up pin must be set to a low inside. Voltage, of course, can also be externally added with a grounding resistor (puU_1〇w resist〇r), 5 to ensure that the voltage level of the wake-up pin is maintained at the ground voltage, and the microprocessor and the wake-up pin are triggered by a positive voltage. It is to be understood that those skilled in the art can understand and implement it. The above embodiments are merely examples for convenience of explanation, and the scope of the rights of the present invention is from the scope of patent application.
