Description of the invention (() The present invention relates to an automatic level adjustment device, and in particular to an automatic level adjustment device applied to a scanner. The scanner is One of the most common computer peripherals at present. For common platform scanners, W generally includes a charge-coupled device (CCD) and a scanning transmission mechanism, usually driven by a stepping motor. CCD It can be directly mounted on the scanning transmission mechanism and scanned directly; or the CCD can be fixed, and the scanning light is transmitted to the CCD through the optical lens group through a group optical lens structure on the scanning transmission mechanism for scanning. And, CCD—read the line image data of one scanning line (Scanning Line, also called Horizontal Line), which is composed of multiple pixels, and its resolution is based on the sensor in the CCD ( Sensor) density. It is generally referred to as Horizontal Resolution or Optical Resolution. As for the vertical direction The scanning is achieved by the scanning transmission mechanism driving the CCD or optical lens group, and the resolution is related to the stepping angle of the stepping motor and the accuracy of the scanning transmission mechanism. It is generally referred to as vertical resolution (Vertical Resolution) '' Or Motor Resolution. By scanning in a vertical direction, multiple line image data can be combined to form a complete image data. As the quality requirements for images are becoming higher and higher today, that is, the resolution of the scanner The degree of demand is also getting higher and higher. If the level of the scanner is not good, it will affect the resolution of the image or cause problems with autofocus. It is really worth the loss. Therefore, the requirements for the level of the scanner during the scanning process are not only An important indicator of scanner quality is also an important lesson to improve the resolution. 3 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling out this page) • I nn n- * ·-一 el 'I n 1 ^ 1 1 ^ 1 I n I · Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 472479 A7 B7 611 ltwf.doc / 008 In fact, during the scanning, in addition to the normal scanning trajectory between the scanning transmission mechanism and the scanned object, there will usually be some relative fine movements, which may be due to the poor level of the scanner. It affects the accuracy of the mechanism itself, or it is caused by vibration. However, the errors caused by these small movements ^ are also important reasons that affect the quality and resolution of the scanner. If the relative movement is too large, it may even cause broken lines in the scanned image. (Smearing), Pixelize, Jitter, etc. Therefore, an object of the present invention is to provide an automatic leveling device that can be applied to the leveling of scanner products. Not only can prevent the poor level of the scanner from affecting the accuracy and image resolution of the mechanism itself. It also solves problems such as autofocus errors and greatly improves the quality of the scanner. In order to achieve the above and other objects of the present invention, an automatic level adjustment device is proposed, which includes: a trigger factor, a plurality of feet, a plurality of contact pads, and an automatic control system. When the scanning device is at an oblique angle, the triggering factor will touch the contact pad because the sliding component force is greater than the static friction force and starts to slide or roll. At this time, the trigger switch located in the automatic control system is turned on and the control of the motor is started to adjust the foot stand to be extended or shortened to ensure the levelness of the scanner. In order to make the above and other objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is described below in detail with the accompanying drawings as follows: Brief description of the drawings: FIG. 1A Figure 1B shows an automatic level 4 according to the present invention (please read Note 3 on the back before filling out this page) Order --------- Line _ Employee Cooperatives, Intellectual Property Bureau, Ministry of Economic Affairs The paper size for printing is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) 472479 611 ltwf.doc / 008 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5.

The level of itself, so that the charge-coupled element will not be out of focus, resulting in blurred graphics. Therefore, an automatic leveling device 100 is installed above the surface of the scanner, which can be used to adjust the foot 102 to ensure the level of the scanner 104. As shown in FIG. 1B, an enlarged detailed view of the automatic level adjustment device 100 is shown. On the surface of the automatic level adjustment device 100, the trigger factor 108 of the device, such as mercury or a metal ball, can be a good conductor for sliding or rolling. When the scanner 100 is tilted to an inclination angle, the trigger factor is triggered. When the sliding component force of 108 is greater than the static friction force, it starts to slide or roll. There are four sets of contact pads 106 around the automatic level adjustment device 100, each corresponding to four feet 102. When the contact pads 106 are in contact with the trigger factor 108, they can be electrically connected and output a signal to the automatic control system to determine the feet. The base 102 is extended or shortened. The shape of the contact pad can be several square metal pads or long metal pads. The purpose is to prevent the trigger factor from sliding or rolling to the edge of the automatic leveling device 100, but it cannot detect that the trigger factor 108 has been touched.
