Description of the invention (1)-·. ------ ------------------------ TECHNICAL FIELD OF THE INVENTION The present invention relates to an image scanning device and a method for operating the same, and more particularly, to a device having Image scanning device with multiple power modules and its operation method. Prior art A scanner is a machine between a photocopier and a camera. In the past, because of the high price, it was almost a patent for some special workers such as art work. In recent years, due to the rapid advancement of computer technology, coupled with the price decline caused by the fierce competition in the scanner market, it has finally entered the mainstream of the personal computer world and become a major player in personal computer peripherals. Scanners can be divided into several forms according to their price or function, while general scanners can be roughly divided into palm-type scanners, paper-fed scanners, business card scanners, film scanners, and platform scanners. Wait. Among them, the flatbed scanner is similar to a glass platform, in which a document or pattern is placed on a flat glass, and then the sensor is moved to read the data. Because its structure is not too complicated, and its use is not difficult, coupled with its highly functional extensibility, it has become the mainstream of computer users with scanners. As for the power supply method of the scanner, almost all current scanners are provided by an external power source, such as a power adapter (P 0 W er adapter), or a rechargeable battery and a solar battery suitable for a handheld scanner. . Currently, a small number of scanners are powered by universal serial bus (USB) power. The advantage of using an external power supply is the power supply

Description of the invention (2) Stable, so when scanning documents or images, the scanning speed will be faster and the scanning time will be shorter; and The disadvantage is that it consumes more power. The advantage of using a universal serial bus power supply is that it saves power. This is because the universal serial bus power supply is provided by the computer host, so no additional external power is required, but the prerequisite is that the computer host must support the universal serial bus. However, the disadvantage is that the scanning power may be insufficient. When scanning documents or images, the scanning speed will be slower, and the scanning time will be longer, especially if other devices are connected to the universal serial bus. This will make the power supply for the scanner even more inadequate. As can be seen from the above, the method of providing the scanner power with an external power supply or a universal serial bus power supply has its own advantages and disadvantages. Therefore, if two or more power supply methods can be provided, it can be based on the needs in different environments. Choose the method that works best. However, there is currently no scanner that can provide more than two power supply methods. SUMMARY OF THE INVENTION ′ In view of this, the present invention provides an image scanning device with multiple power modules and an operation method thereof. Because the image scanning device of the present invention has a plurality of power supply modules, two or more power supply modes can be selected, so the most suitable method can be selected according to the needs in different environments. To achieve the above and other objectives, the present invention provides an image scanning device with multiple power modules. The image scanning device includes a plurality of power supply modules, multiple power checking circuits, an image scanning control circuit, and an image reading device. Among them, these power supply modules are connected to several power supply devices, and these power supply devices are used to provide this image scanning.
