Abstract
A background replacement device of an image scanner belongs to the image scanning technical field, including a rack, a press board, a connecting block, a positioning pin, a junction plate, a slipper block, a floating spring, a positioning groove and a positioning spring; the press board is composed of a black background plate and a white background plate; the black background plate and the white background plate have the same structure, which are arranged in a relative location to the connecting block, one for upper side and one for lower side; the slipper block is arranged on the junction plate of the two end of the white background plate, and the floating spring is arranged into the slipper block, under the effect of the floating spring, the black background plate keeps a elastic contact with the outer surface of a scan head; the positioning pin is arranged on the outer end of the connecting block and also arranged within the positioning groove for providing positioning orientation for the upper and lower displacements of the positioning pin on the rack; the positioning spring is located outside the rack. The replacement method of the black background board and the white background board is as follows: toggling the positioning spring outside the two sides of the rack and taking out the whole press board; rotating the pressure board by 180 degrees and re-installing the press board to the original place, thus completing the replacement of the black background plate and the white background. The invention has the advantages of reasonable design, simple structure, easy manufacturing and convenient application.
Description
Technical field
The present invention relates to a kind of apparatus for replacing background of image scanning apparatus, belong to the image scanning technical field.
Background technology
In the image scanning apparatus such as conventional scanner, all-in-one machine,, need to change the scanning background color and reduce influence, to reach high quality image quality as much as possible to the image scanning quality for the paper of opening that satisfies unlike material and quality adapts to.For example: generally, use the black background look for the ease of the correction and the cutting of scan image; When scanning translucent or transparent manuscript, use the black background look generally can seem secretly, even scan image can't be discerned.For avoiding of the influence of back side information to scan image, need to use the white background look, make to form and produce whiter image, black background forms and produces black image when lowering scanning.This just needs the replaceable device of a kind of scanning background plate, makes the user realize changing the purpose of scanning background plate easily and efficiently.Yet there are no the patent application or the bibliographical information of the replaceable device of scanning background plate.
Summary of the invention
At the defective of prior art, the invention provides a kind of reasonable in design, simple in structure, apparatus for replacing background of making image scanning apparatus easy, easy to use.
A kind of apparatus for replacing background of image scanning apparatus comprises frame, pressboard, contiguous block, alignment pin, connecting plate, slide block, unsteady spring, location notch and back stop; Pressboard is made up of black background plate and white background board; Black background plate and white background board structure are identical, and positioned opposite is installed on the contiguous block up and down; Slide block is positioned on the connecting plate at white background board two ends, and a unsteady spring is set in the slide block, and black background plate and probe outer surface keep Elastic Contact under the effect of the spring that floats; Alignment pin is installed on the outer face of contiguous block, and is positioned at the location notch that positioning and guiding is provided for the upper and lower displacement of alignment pin on the frame; Back stop is positioned at the outside of frame.
Described black background plate and white background board structure are identical, and one guiding surface are all arranged going into the paper side.
The replacing method of black, the white background board of the apparatus for replacing background of image scanning apparatus is as follows: outwards stir the back stop in the outside, frame two ends, whole pressboard is taken out; After pressboard turned over turnback, reinstall reposition, back stop is located whole platen version, realizes the replacing of black, white background board.
In the use, the pressboard two ends keep Elastic Contact with the probe outer surface under the thrust of buoyancy spring, and can change up and down along with the variation of scanning paper sheet thickness, make paper be adjacent to image sensor surface all the time, thereby guarantee the scan image quality.
That the present invention has is reasonable in design, simple in structure, make characteristics easy, easy to use.
