Description

scanning system

technical field

The utility model relates to a file scanning system, in particular to a scanning system capable of directly scanning bound files. Its roof-shaped load-bearing structure can effectively eliminate the height difference between the binding of the page number of the scanned object and the scanning plane, thereby obtaining a normal , Undistorted, undistorted scanned images.

Background technique

The key components of a scanner or scanning system mainly include image sensing components, light sources (cold cathode tubes or LED array tubes), color filters, lens groups, combined motors, combined power supplies, etc. The method is that a light source first irradiates the light on the manuscript to be scanned, and the light reflected from the manuscript is projected along the optical axis through the lens group and the color filter, and then by a CCD (Charge-Coupled Device, Charge-Coupled Device) component) to receive the sensing component.

Because the darker areas on the paper reflect less light, and the brighter areas reflect more light, and the CCD can detect different intensities of light reflected from different areas on the image, so the CCD converts the reflected light waves into digital data, using 1 It is represented by a combination of numbers and 0 (called a bit, which is a binary value). Finally, the scanning software that controls the operation of the scanner reads the data and reassembles the microcomputer image file.

The scanners or scanning systems used in the prior art can meet the scanning applications in most cases. However, when scanning bound documents, such as books and magazines, the bound edges of such documents cannot be flattened with the scanning window. As a result, the intensity of light sensed on the document is inconsistent, resulting in distortion of the scanning effect.

Therefore, in order to make the scanning surface of the book or magazine flat and completely face down on the scanning window to complete the scanning operation, and to ensure that the surface of the paper is completely in contact with the surface of the platform, it is known that the book or magazine The binding part of the paper is removed, and then the area to be scanned is fixed on the glass platform to solve the above-mentioned problem of scanning distortion; in addition, another method is to add a precise scanning software system, through the calculation of the software, the original scanning The instrument can effectively scan books and magazines, and even three-dimensional (3D) objects, such as flowers or toys; known methods usually use a long focal length depth scanner, so that the text in the central part of the book can also be printed clearly, or The original diagonal setting function and the curved top cover are adopted to improve the scanning quality of bound books, so that the scanned image will not be shifted or bent.

Although the above-mentioned various methods all can solve the defects produced when scanning and binding books in the prior art, the above-mentioned methods have the following disadvantages:

1. Removing the binding part of a book or magazine often destroys the original integrity or aesthetics of the book or magazine.

2. Using a more accurate scanning software system or a long-focus depth scanner will increase the cost of the scanning operation, and the image needs to be processed through another software system, which will waste operating time and cannot meet the needs of fast scanning .

Contents of the invention

The main purpose of the utility model is to provide a scanning system, which can directly scan bound books or magazines without removing the binding, and does not need to use scanning software to achieve the purpose of fast scanning.

A pair of scanning windows are arranged side by side on the upper surface of the casing. The outer edges of the pair of scanning windows are covered by frame edges, and the inner edges of the pair of scanning windows are surrounded by a support frame to jointly form a scanning document platform.

In order to achieve the above purpose, the scanning system of the present invention also includes the following other technical features,

The photosensitive scanning device provides a light source with a U-shaped structure;

The upper surface of each scanning window is higher than the upper surface of the supporting frame;

A pair of positioning slots are provided on both sides of the support frame, wherein each scanning window is provided with a downwardly inclined plane or a stepped shape to fit into the positioning slots;

Each positioning groove includes an upper edge portion and a lower edge portion, the upper edge portion has a downwardly inclined plane, and the lower edge portion has a horizontal plane to form the positioning groove.

Through the above structure, the file scanning system of the present invention can directly scan the bound books and magazines without avoiding the removal of books and magazines, and it is not necessary to use scanning software to operate. Effectively eliminate the height difference between the page binding of the scanned object and the scanning plane, and then obtain a normal, undistorted, and undistorted scanned image. At the same time, the scanning process is simple and fast, and no additional scanning cost will be added.

Other technical features and implementability of the scanning system will be further described below in conjunction with the accompanying drawings and specific embodiments of the present invention.

Detailed ways

Please refer to Fig. 1, Fig. 2A and Fig. 2B. Fig. 1 is a schematic diagram of the three-dimensional appearance of the utility model. The scanning system of the present utility model includes at least one roof-shaped casing 3, which is provided with a pair of photosensitive scanning devices 31 inside, and a pair of scanning windows 34 are arranged on the roof-shaped casing 3, and the pair of scanning windows 34 form a document platform The pair of photosensitive scanning devices 31, which are arranged under the document platform 34, during the scanning operation, the projected document passes through the photosensitive image medium to form a latent image; the outer edge of each scanning window 34 is inlaid with a border 33', and its A supporting frame 33 is inlaid between the intersection of the two scanning windows 34 on the inner edge, wherein the upper surfaces of the two scanning windows 34 are substantially equal to or higher than the height of the supporting frame 33, therefore, during the scanning operation, the scanned document, especially The edge portion of the book or document can be placed in the position of the support frame 33, so that the entire surfaces of the two pages of the book or document can be completely attached to the two surfaces of the side-by-side scanning window 34 at the same time, so that accurate scanning or copying can be obtained.

As shown in Figure 2B and Figure 2C, the scanning system further includes a pair of positioning grooves 331 arranged on both sides of the support frame 33, the support frame 33 can be an aluminum extruded support frame or a support frame made of plastic materials, Each scanning window 34 has a downwardly inclined plane 341 or a stepped shape 342 embedded in the positioning groove 331. Each positioning groove 331 includes an upper edge portion 332 and a lower edge portion 333, wherein the upper edge portion 332 has a downwardly inclined plane. 334 corresponds to a downwardly inclined plane 341 of the scanning window or a stepped surface 336 corresponds to a stepped shape 342 of the scanning window, and the lower edge portion 333 has a horizontal plane 335 to form the positioning groove 331 .

Please refer to FIG. 3 , which shows that the photosensitive scanning device 31 of the present invention provides a light source 32 with a U-shaped structure. Compared with the traditional photosensitive scanner utilizing a light source with a linear structure, the light source 32 with a U-shaped structure can effectively Shorten the distance between the scanning area of the photosensitive scanning device 31 and the roof-shaped housing 3, so that the utility model can effectively shorten the width of the photosensitive scanning device 31, and the scanning window 34 is an exposure glass.
