Description of the invention () Background of the invention: The present invention is a multi-resolution image capture device, especially an image processing device that has two optical resolution yielding functions on M and uses non-lens movement Multi-resolution image reading device that switches the image reading mode. The image source of a general image reading device is a file, a photo, or a slideshow. The optical resolution and area available for a document, photo, or slide show differ. For example, when capturing general documents, it is most suitable to read images with a reading area of 210mm and a reading length of 297mm (that is, A4 size) and an optical resolution of 300DPI (dot per inch); and when reading photos , An image reading mode with a 4-inch capture width and a 6-inch read length and an optical resolution of 300 DPI is the most suitable; while when capturing a slideshow M or a small-area picture, the optical must be further improved The resolution is 1200 DPI, and the image will not appear rough after it is enlarged, but it only needs a grabbing area of about 24nun reading width and 36mm reading length. The image reading device, whether it is a sheet-feeding or flat-closing type, usually provides a fixed image reading wedge type for a single purpose. For example, most image capturing devices on the market dedicated to capturing general documents have A4 Size of the capture area and provides a lower optical resolution; while the image reading device designed for reading photos · provides a smaller capture area but has a higher optical resolution; and is designed for reading The image capture device that takes slides only provides a reading area of about 24 bands x 36 pm, but has the highest optical resolution. Therefore, when buying, users must first consider their use and what form they use. Image reading device, and if there are many different needs—2- ί Paper size applies to China B country car (CNS > A4 specification (2101 × 97 male D ~~ Α7 Β7 409229) gas: description of the invention () * It is necessary to purchase different types of image capture devices separately, which causes considerable inconvenience for users. To solve the problem of conventional image reading devices that have only a single optical resolution and lack of black, 'multi-resolution image reading devices have appeared in In the market, for example, the "multi-lens switching mechanism of the Republic of China Patent Bulletin No. 232398, and the" multi-lens switching device of the scanner "of the Republic of China Patent Bulletin No. 311712, a multi-resolution image capture is proposed. Device, this type of image reading device has multiple sets of lenses with different optical resolutions, using a single CCD (Charge Coupled Device) sensing element, and using a machine The above-mentioned lens is moved in such a way that the _ heads of different optical resolutions correspond to the CCD sensing elements, so as to achieve the purpose of changing different image reading modes. However, in addition to the conventional multi-resolution image capturing device, a plurality of different optical resolutions must be provided. In addition to the high-resolution lens, it is necessary to reserve a space for the lens to move when switching the optical resolution. M. Instead, a driving mechanism and a positioning device for driving the above lens are separately installed, so that it is used a lot. The volume is quite large; and because the lens is movable instead of fixed, its optical image is very susceptible to vibration, which reduces reliability and image quality. The inventors have been thinking hard and actively researching this in view of this. After adding years of experience in R & D of related products and continuous testing and improvement, the invention has finally been developed.

Description of the invention (1) After the surface 21 of the material 21 is obtained, the light 71 is reflected by the material 21 to be captured, and then transmitted to the lens group 50 through the mirror group 40. The aforementioned lens group 50 is composed of several lenses with different optical resolutions, and the optical output can be focused on the aforementioned sensing device 60 along the optical output plane to convert the optical output into an electronic signal output.

Description of the invention () Output plane 86 to form optical output 83 of the third optical resolution. As shown in FIGS. 9 and 10, when the present invention is in the highest optical resolution mode, the optical image of the data 21 to be read is reflected by the reflection lenses 41 and 42, and the light is transmitted into the lens 54 and then passed through the lens. 54 forms a fourth optical resolution optical output 84 along the second optical output plane 86. Since this image reading device uses linear sensing elements (Li n e ar type Charge Coup led Dev ice), the ancient texts only require image data. In order for the image reading device to capture the image of one side, it is necessary to use a driving device (not shown) to drive the data 21 to be captured or the image reading horizontal group 30 to move. Image data. Only the movement of the driving device that drives the data 21 to be captured or the movement of the image reading horizontal group 30 must be adjusted in accordance with the optical resolution of each lens. Μ makes the data 21 or the image to be captured horizontally. The distance between the group 30 and the pixels in various optical resolutions can be matched (for example, at 300 DPI, the distance between the data to be captured or the image reading module should be 1/300 inches) Therefore, the optical resolution of the lenses 51, 52, 53, 54 of the lens group 50 of the present invention can also be designed to adopt a simple integer ratio (for example, the ratio of 400 DPI, 600 DPI, 1200 DPI, and 2400 DPI, or It is a ratio of 300 DPI, 600 DPI, 1200 DPI, and 2400 DPI), and M simplifies the control of the driving device. The most important feature of the present invention is that the sensing device 60 has four sensing elements 61, 62, 63, and 64 respectively corresponding to the lenses 51, 52, 53, 54 of different light lift resolutions. The sensing elements 61, (32, 63, and 64) used in this embodiment are CCD light-cooking elements, which are capable of adapting the aforementioned light -10- paper size to the Chinese National Standard (CNS) A4 specification < 210 X 297 mm) (Please read the note on the back before filling out this page) 0 Pack _ Order printed by the Central Standards Bureau of the Ministry of Economic Affairs and Consumer Cooperatives printed 409229 A7 __________B7 V. Description of the invention () The academic output is converted into an electronic signal output. As shown in FIG. 3 to FIG. 10, the positions of the components 61, 62, 63, and 64 are aligned with the aforementioned lenses 51, 52 '53, 54 respectively, and only corresponding lenses can be received respectively. The light lift output passed. Therefore, by combining the sensing elements 61, 62, 63, and 64 with the lenses 51, 52, 53, and 54, the optical outputs 81, 82, 83, and 84 in the four different optical resolution modes can be converted into Electronic signal output in four different optical resolution modes. As shown in FIG. 16, in the control circuit of the present invention, an electronic signal output of at least one of the sensing elements 61, 62, 63, and 64 is controlled by a multiplexer 90 and transmitted to an image processing and control unit 91. The image processing and control unit 91 then sends the processed electronic signal _out to a computer (or other device) 92 for subsequent processing. In addition, the control circuit also includes a user interface unit 93 for the user to control the multi-resolution image reading device and switch the scanning mode. M and a driving system 94 are used to drive the image reading horizontal group. 3 0 or movement of pending data. The switching operation of the multiplexer 90 described above can be performed by the user through an instruction from the user interface unit 93 to cause the multiplexer 90 to switch, or a command can be issued from the computer 92M to control the multiplexer 90. Switching action. In addition, the control circuit design of the present invention can also change the multiplexer into a switch, and M is provided for the user to directly control the switching action of the electronic signal output of the sensing elements 61, 62, 63, and 64 with the switch. The design of the present invention is based on M. Since each lens 51, 52, 53, 54 of different optical resolution has a corresponding sensing element 61, 62, 63, 64; therefore, when switching the image speaking mode, Can be borrowed completely 11- This paper size applies to Chinese National Standard (CNS) A4 specifications (21〇 × 297 mm) (Please read the precautions on the back before filling out this page) Binding --------- ^- --1 .
