Description of the invention (3) Directly using the bus power on the personal computer can sufficiently supply the current demand of this scanning device. Another object of the present invention is to provide a scanning device that saves the cost of a sensing element. According to the above-mentioned purpose, a color charge coupled element that replaces a general color scanning device with a black-and-white electric element is used. The light sources of each color of the array emit light in a time-sharing manner, so that a black-and-white charge-coupled element can also be used to scan a color document or picture. Because the cost of black and white charge-coupled devices is lower than that of color charge-coupled devices in the case of mass production, the scanning device of the light emitting diode array light source can achieve the purpose of saving energy and cost at the same time. In order to make the above-mentioned objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is given below and described in detail with the accompanying drawings as follows: For a preferred embodiment, please refer to FIG. 5, which depicts Shown is a perspective view of an optical machine of a scanning device of a light emitting diode array light source according to a preferred embodiment of the present invention. The light emitting diode array 503 is located in the light machine 501. When the document to be scanned starts to be scanned, the light emitting diode array 503 will emit light according to the light sources of different colors. This light-emitting diode array 503, in particular, uses a light-emitting diode (LED) array, because the power consumption of the light-emitting diode array is relatively small, which can reduce the power requirements of the scanning device without using Extra power supply. Please refer to FIG. 6, which is a perspective view of a scanning device of a light emitting diode array light source according to a preferred embodiment of the present invention.

Description of the invention (4) The output signal line 6 03 is used to connect a personal computer (not shown in the figure). The personal computer also provides a bus power to the scanning device via the signal line 6 0 3. In this way, in addition to saving energy, the cost of the power supply can also be saved, thereby reducing the packaging difficulties of the scanning device. Please refer to FIG. 7, which illustrates an optical path diagram of a scanning device of a light emitting diode array light source according to a preferred embodiment of the present invention. The scanning platform 703 is located above the casing 601, and the document to be scanned (not shown in the figure) is placed on the scanning platform 703.

In addition, the optical machine 501 also includes a black-and-white charge-coupled element 708 and a lens module 709. When starting to scan the document to be scanned, the light emitting diode array 5 0 3 will emit light according to the light sources of different colors in time and reflect by the scanning platform 7 0 3 to obtain an optical image, and then this red image is passed through the lens module 7 0 9 The green image and the blue image are in focus, and are received by the black and white charge-coupled element 7 0 7 and converted into a red image signal, a green image signal, and a blue image signal respectively. Therefore, although the black-and-white charge-coupled element 7 0 7 used in this scanning device can still scan a color document or picture, it can replace the color-charge-coupled element of a conventional scanning device. Moreover, in the case of mass production, the cost of the black and white charge handle element 707 is lower than that of the color charge handle element, which can save costs. [Effects of the Invention] The scanning device of the light emitting diode array type light source disclosed in the above embodiments of the present invention has the following advantages: 1. The light emitting diode array type light source scanning device uses the light emitting diode
