A platform and an image reading device move in opposite directions at the same time. Faster scanning speed. Device and side B. Background of the invention + There are many types of transmission structures known as desktop scanning benefits, but the transmission type structure. As shown in Figure 丨% > It is a known platform scanner. The document is placed on the file platform v ^ ^ 10, and an image reading device 13 is driven by a transmission U, driven by Bu Huaimin and Taijin Ma Jian. The image of the document is read step by step. The other is a paper-feeding image scanning device, as shown in Figure 2. The image reading device 21 is fixed in the machine α 22 'and the document 23 is in the paper feeding device (not shown in the figure). (Picture) Driven by the thorns and the ground, k gradually feeds into the machine 22 »As the file gradually passes through the upper part of the image reading device 21, you will be able to read the image of the file by the image reading device 21 .The above two types of extrusion furnaces & ^ Sou Ye also have a unidirectional transmission structure Mainly, that is, there is only one type of machine broadcast at the same time, and the & m 1 is reverting in the early direction, so the scanning speed is also limited by the speed of the motor's one-way traffic from α, which is difficult to break through. Speed, the conventional imager is often improved by software or hardware. For example, 'high image compression and decompression speed' can increase the speed of image transmission to the computer.

Description of the invention () The transmission mechanism inside the scanner shortens the scanning time. However, 'the software solution must be coordinated by the scanner manufacturer and driver developer, and the compression / decompression rate is often higher than the speed of image transmission.' Therefore, the bottleneck of scanning obsession lies in the speed of computer transmission, and Uncompressed / decompressed fast. In addition to replacing the low-speed motor with a high-speed motor, in addition to high cost, the speed of the high-speed motor is still not as fast as the image reading device can read the image of the document. Therefore, how to improve the scanning speed and shorten the scanning time is the direction of the joint efforts of the scanner industry => 5-2 The purpose and summary of the invention In order to break through the known technical bottleneck, the main purpose of the present invention is to propose a file platform An image scanning device that moves simultaneously with the image reading device in order to increase the scanning speed. Another object of the present invention is to improve the scanning efficiency of an image by utilizing the mature stepper motor control technology. Based on the above-mentioned object, the present invention proposes a scanning device that utilizes a file platform and an image reading device to move in opposite directions at the same time. Its operating principle is to use two transmission mechanisms in reverse motion to drive the file platform and image reading device at the same time. As a result of the reverse relative motion, the distance that the image reading device moves will not be greater than one-half the original distance, and the image of the finished document can be read, so the scanning speed can be increased by at least twice. The device of the present invention includes: a document platform for carrying documents.

Since the driving element is connected to the image reading device 34, the driving element 352 of the image reading device may be a belt or a cable. 43 4 The motor 333 that drives the document platform 32 and the motor 353 that drives the image reading service rate drive the roller sets 332 and 352 in the opposite direction, and the Dongwentai 32 and the image reading shaker 34 move in parallel and in the opposite directiona When the scanner is built, the image reading device 34 is located at the initial point p and is at the top of the file contention. When scanning is started, the image reading device 34 moves toward the B-side work document platform 32 at the same time in the direction a. Because it is a relatively automatic, Λ. ^ System, when the image reading device is moved to the q point, the technology file 'top image reading has been completed. The distance between p and q in the case of motor 333 and another motor 353 is not greater than the length of the document platform 32—half ^ In other words, the speed of scanning the document can be at least doubled. Of course, in practical application, the transmission structure of the present invention has many possible changes, as long as the transmission directions thereof are opposite. The mechanism 'shown in Fig. 4 is another embodiment of the present invention. The document platform 41 shown in Fig. 4A is located above the machine 40 * and is supported by a pair of support shafts 42a '42b. The document platform 41 is connected to a pair of lead screws 45a, 45b to reciprocate back and forth as the lead screws 4 5a, 4 5b rotate. The lead screw 4 5 a is connected to the roller 46 a.
