Description of the invention (/) [Application range of the invention] The present invention is Patent Application No. 77105326 (Patent case number: 34146) Roller-driven optical color line scanning and imaging Addition of devices. It is about a color optical scanning and imaging module: in particular, it is about the structure of the imaging part in an optical scanner that uses color filters to achieve color optical scanning. The imaging module provided by the invention has the functions of further improving scanning efficiency and miniaturizing the mechanism. [Background of the invention]. Optical image scanner is an important input device for computer system. It can be used to input graphics and / or text images for processing by the computer system. Used in text recognition (OCR), image processing (Image Processing) technology, it is quite convenient. The principle of the optical image scanner is to use a charge-coupled device (CCD) with a row of image sensors to sense the image data recorded on the scanned medium (such as paper) line by line and output it in computer system. Since the charge-coupled device only senses the brightness of the image recorded on the medium, it is suitable for black-and-white processing of the image. If you need to engage in color processing, you can use, for example, three primary color filters to filter out the three primary color components of the scanned image, input them to a computer system, process them, and then combine them into a color image with three primary color components for processing. [Original invention] Republic of China Patent Application No. 7 7 1 0 5 3 2 6 is for the same applicant | Please refer to a "roller-driven optical color line scanning and imaging device". This invention is the original invention of this case. It uses a color filter wheel, which is placed in front of the lens of the image scanner, and the color image information on the medium is obtained by the rotation of the wheel.

Invention Description (2) Article 1 The figure shows a plan view of a color optical scanner as shown in Republic of China Patent Application No. 7 7 1 〇5 3 2 6. As shown in the figure, the scanner includes a media movement module and an imaging module. Media movement The module uses the movement of the medium (paper) or the imaging module to make relative movement between the scanned medium and the imaging module. The imaging module is used to read the data on the medium, including a light source (1). Separation wheel (2), a lens (7) and ―detector group (8). After the light emitted by the light source (1) reaches the media, the image components on the loaded media, after reflection, reach the separation wheel (2) After wearing the color filter-film (3) (4) (5) (6), only the color components of the color filter are saved, and after entering the lens (7), focusing, the photosensitive linear detection of the charge-coupled device is achieved Detector group (8). The output of the detector group (8) is the same as the content of the image, and an electronic signal is formed. The interface enters the computer system. The working principle of the above device is that when the scanning operation is performed, the scanner imaging module is driven by the media movement module to move relative to the scanned media. At the same time, the color separation The rotating wheel (2) rotates at a certain rate, so that the color filters of different colors sequentially pass in front of the lens (7), and the detector group (8) picks up image color components recorded on the media at different times, respectively. Figure 2 shows the front view of this scanner imaging module, Figure 3 is its plan view, Figure 4 is its right side view. In addition, Figure 5 (a) to (d) shows this scanner In the imaging module, a color filter passes through the lens (7) · and the detector group (8) exposure schematic diagram. [Original invention] As shown in the figure, the above-mentioned original scanner imaging module, although having The efficiency is improved, but there are still thousands of shortcomings in the application, which still need to be overcome. First, in this device, because the detector group is a group of linearly arranged detectors, the direction of travel of the color filter For the detector group, it moves laterally. When the wheel rotates, the detector group is partially exposed (Figure 5 (a)), and then (please read the notes before you write the book) Γ ·.

Description of the invention (3) and fully exposed (Figure 5 (b )) (Figure 5 (c)) and partial exposure (Figure 5 (d)); the exposure time of each detector in the detector group is not consistent, and it needs to wait for one moment of all exposures before driving the detection It accepts exposure. Therefore, it is time-consuming to control, and the increase of scanning speed is not completely satisfactory. Secondly, due to this setting tt ', the width of each color filter must be at least greater than the total length of the detector group, such a mechanism is not easy to increase the number of color filters contained in each wheel, nor can it achieve further rotation. The miniaturization of the wheel hinders the miniaturization of the machine. Furthermore, due to the above restrictions, the shape of the color filter is limited, which makes it difficult to cut or develop the production of the color filter. At the same time, there are only 4 color filters, but one of them is used for black and white scanning. The color filter is not installed, so that the center of gravity of the wheel cannot be located at the center (center of the wheel), and it is difficult to maintain stability when rotating. Finally, because the detectors must all be exposed at the same time, scanning takes time. If high-speed scanning is required, the motor needs to rotate at high speed, which will reduce the life of the mechanism. Therefore, how to manufacture a color optical scanner imaging module that saves material, reduces volume, is easy to construct, and increases the scanning speed has become the goal of unanimous efforts in the industry. [Object of the Invention] The object of the present invention is to provide a color optical scanner imaging module with higher efficiency and more compact mechanism based on the above Patent No. 7 7 1 0 5 3 2 6. The object of the present invention is also to provide an imaging module for a color optical scanner that enables the image scanner detector group to be exposed at the same time.

When the next color filter enters above the sensor group (8), the above action is repeated again. So again and again. [Effects of the invention] In this example, since the lower edge of the color filter (and the color filter window) is formed in a linear shape, each time a color filter passes through the sensor group (8), all sensors It was exposed at the same time, not the device as originally invented, which was successively exposed. In other words, the sensor can be exposed at the same time, while shading at the same time, the control and scanning of the device, the scanning effect, the effect is greatly improved. Moreover, due to the above design, the area of the color filter window required by the mechanism is greatly reduced, and the angle of each color filter window on the color separation wheel is greatly reduced compared with the original invention, so it can be added on the wheel The color filter window and color filter, so the rotation speed of the runner can be reduced by a ratio of 1 / η, extending the life of the mechanism. At the same time, the cutting and production of color filters have a simplified effect. In this example, 8 color filter windows are provided, so the color filter windows without a color filter are opposed to each other: in the case of 12 or 16 color filter windows, the same is true. As a result, since the filter windows without color filters are arranged symmetrically, the center of gravity of the runner is located at the center of the circle, so the operation is extremely stable and the stability of the device is improved. ^ In addition, when the light source (1) is a daylight lamp, the brightness on both sides of the light source is often insufficient: coupled with the lens (7) spotlight feature, the image data is loaded into the sensor group (8) The brightness of the light is brighter in the middle and darker on both sides, which can easily affect the quality of the scan. In this sinus example, a rectangular cover (! 2) is provided between the runner (2) and the lens (7). The light grid has a rectangular or elongated hole with two flanges (as shown in Figures 10 and 11) to reduce the brightness of the central part of the light under test and / or increase the two sides brightness. In other examples of the present invention, the color separation wheel (2) is not directly driven by the motor, but is driven by a belt and a pulley. This type of paper is used in the center of the motor rotation wheel. The standard is a standard (CNS) TM specification (210x297 g *) S1. 2. 20,000 Λ 6 Π6 V. Design description (?) , Can avoid limiting the size of the runner due to the size of the motor's further miniaturization. At the same time, this design can be used in the application of so-called flat-bed scanners, which can use the movement of the imaging module in the scanner to "drive the wheel" to save the installation of motors. In the so-called sheet_feed scanner, the power of the paper_sheet drive wheel can be used to drive the runner. In another example, the system uses gears to drive the runner, and similar effects can be obtained. · In the present invention, the motor can be charged by a DC motor or a stepping motor. During continuous color separation scanning, the continuous rotation of the rotating wheel is driven by a DC motor, and the primary color components can be scanned sequentially in sequence. However, if a stepping motor is used, the wheel can be fixed at each filter position of red, blue, green, or black / white / gray, and the images contained on all the media can be scanned once, respectively, and the so-called "fractional" scanning can be performed. The additional invention can be applied to sheet-feed type, flat-bed type or hand-held scanners, and excellent effects can be obtained. Furthermore, whether the scanner uses reflective scanning (such as scanning paper) or transmission scanning (such as scanning slides), the imaging module of the present invention can be used to perform color scanning. The above is the description of the embodiments of the present invention. It is not difficult for those who are accustomed to arts and crafts to learn the spirit of the present invention from the above description and make different changes. As long as it does not exceed the spirit of the present invention, it should fall within the scope of the present invention.
