Embodiment Construction

[0009] The technical solutions of the embodiments of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0010] A scanner generally includes a housing and a scanning processing device built in the housing. The upper surface of the housing is provided with a glass table for carrying the scanned image. The scanned image is placed upside down on the glass table, and the scanning processing device can scan the scanned image Scanned and imaged. figure 2 It is a schematic structural diagram of the scanning processing device in the scanner of the present invention, such as figure 2 As shown, the scan processing device 5 in the scanner provided by the present invention includes a major axis 1 and a linear CCD frame 2, wherein the linear CCD frame 2 is provided with a lens, a photoelectric sensor, a light source, etc. (not shown) for completing Scanning imaging of the scanned image; the long axis 1 is used t...

Abstract

The invention provides a scanner, which comprises a linear CCD frame used for scanning imagery and a prolate axis used for providing scanning stroke, wherein a first end of the linear CCD frame is set up on the prolate axis; the prolate axis is provided with a first bracket connected with a second end of the linear CCD frame and a second bracket connecting the linear CCD frame and the first bracket; and the linear CCD frame, the first bracket and the second bracket form a right-angled triangle structure which takes the first bracket as a hypotenuse. By applying the relative stabilization principle of the triangle, the invention adds the first bracket and the second bracket on the prolate axis of the scanner and leads the first bracket, the second bracket and the linear CCD frame to form atriangle by mutual connection so as to increase the stability of the linear CCD frame in the horizontal direction and reduce the scanning mechanical error caused by the vibration of the linear CCD frame, thus leading the scanning pattern image to be more clear and improving the scanning quality.

Description

technical field [0001] The invention relates to the technical field of image scanning, in particular to a scanner. Background technique [0002] With the popularization of office computer technology, scanners have gradually become an indispensable important equipment for people's offices. The application scanner can scan documents, photos, etc. into a computer-readable format for people to use. [0003] figure 1 It is a structural schematic diagram of a scanning processing device in an existing scanner. The main part of the scanner includes a housing on which a glass table is arranged to carry the scanned image, and a scanning processing device 5 is arranged inside the housing (only this part of the structure is shown in figure 1) ,Such as figure 1 As shown, a long axis guide structure 1 (hereinafter referred to as: long axis) is arranged along the horizontal direction of the scanner in the device, and a linear CCD frame 2 is arranged on the long axis 1, and the linear C...
