Abstract
The invention discloses a double-sided scanning flatbed scanner comprising a main scanning device (1) and a transmission mechanism. The double-sided scanning flatbed scanner is characterized in that the main scanning device (1) and a second scanning device (2) are respectively positioned on the upper side and the lower side of a manuscript to simultaneously scan the front side and the back side of the manuscript; the second scanning device (2) is installed inside a cover plate (3); the cover plate (3) can rotate by taking a sliding rail (4) as an axis; meanwhile, the second scanning device (2) also rotates along the cover plate (3). The double-sided scanning tablet scanner can be used for carrying out high-precision double-sided scanning on various bills, identity documents and the like and is practical and simple.
Description
Technical field
The present invention relates to a kind of flat bed scanner, particularly can disposablely finish the scanner of duplex scanning.
Background technology
The step of existing flatbed scanner scan image is: at first the original copy face down with desire scanning is layered on the glass plate of scanner, and original copy can be literal contribution or drawing photo; Start scanner then, the movable light source that is installed in scanner inside begins scan manuscript.In order evenly to illuminate contribution, the scanner light source is a strip, and along the inswept whole original copy of y direction; The light that shines on the original copy passes a very narrow slit after reflection, formation is along the light belt of x direction, change light belt into analog electronic signal by photo-electric conversion element, this signal is changed into digital electronic signal by the A/D converter again, at last data is sent to computer.Scanner is whenever swept the image information that delegation just obtains original copy x direction delegation, along with along the moving of y direction, progressively forms the full figure of original copy in computer-internal.
Existing flatbed scanner is general only to carry out single-sweep to original copy, and this also meets most application demand.But then need the positive and negative of scan manuscript simultaneously, for example various bills, all kinds of identity documents or the like for some specific application scenarios.
The equipment that can support duplex scanning is also arranged in the existing equipment, but these equipment are autoamtic paper feeding formula scanner, from aspect analysis-by-synthesis such as scanning accuracy, contour size of the unit(s), simplicities of operation, its Design and Features can not satisfy the existing application demand.
Summary of the invention
Purpose of the present invention then is at above-mentioned the deficiencies in the prior art, for satisfying the application demand of duplex scanning, has designed a kind of disposable scanner of finishing duplex scanning.
Purpose of the present invention can realize by following measure: the present invention has increased by one second scanner 2 in scanner.The Master Scanner 1 and second scanner 2 lay respectively at the both sides up and down of original copy, the tow sides of while scan manuscript, and second scanner 2 is installed in cover plate 3 inside.
Beneficial effect of the present invention is:
Transform by covering plate structure, in flatbed scanner, realize the disposable duplex scanning of finishing flatbed scanner.This equipment is simple and practical, owing to kept the design of cover plate, that original copy can keep is smooth, scanning accuracy is guaranteed, and flatbed scanner is simple in structure, makes the pattern of duplex scanning to use widely.
Description of drawings
Fig. 1 is a structure principle chart of the present invention.
Among the figure: 1, Master Scanner; 2, second scanner; 3, cover plate; 4, rail plate; 5, guide rail; 6, connector; 7, transparent plate; 8, hinge; 9, housing; Shadow positions is an original copy.For ease of describing, omitted in the front view cover plate 3 has been reached the wherein mark of associated components.
Embodiment
Rely on the basic general knowledge of this area below, in conjunction with the accompanying drawings the present invention be further described:
Duplex scanning flatbed scanner of the present invention, the Master Scanner 1 and second scanner 2 are driven by same rail plate 4, and the Master Scanner 1 and second scanner 2 lay respectively at the both sides up and down of original copy, simultaneously the tow sides of scan manuscript.In scanning process, Master Scanner (1) and second scanner (2) are done synchronously along the direction of rail plate (4) and are moved back and forth, and it is unanimous between the higher and lower levels that both scanning positions keep.
At cover plate 3 internal fixation two parallel guide rails 5 are installed, guide rail 5 installation directions are parallel with rail plate 4, the two ends of second scanner 2 are enclosed within on two guide rails 5, by connector 6 second scanner 2 is fixedly connected with Master Scanner 1 then, so just make second scanner 2 to link, reciprocatingly move in the Y direction with Master Scanner 1.
One end of second scanner 2 is enclosed within rail plate 4, and the other end is enclosed within on the guide rail 5, and guide rail 5 is installed in cover plate 2 inside, and installation direction is parallel with rail plate 4.Such second scanner 2 can only slide or along with the rotation of cover plate 3 serve as spool to do rotation with rail plate 4 along the Y direction along with rail plate 4.Guide rail 5 can make second scanner 2 more accurately steady along the slip of Y direction.
The times of exercise that lifts and depress of considering cover plate 2 is more frequent, and second scanner 2 that is installed in cover plate 2 inside for assurance can steady in a long-termly move, and that cover plate is designed is lighter, durable as far as possible, and concrete measure is as follows:
1, for the application of duplex scanning, the required precision of scanning reverse side image generally can be lower than positive image, and therefore the photo-electric conversion element that uses in second scanner 2 can be CCD photo-electric conversion element or lighter CIS photo-electric conversion element.
2, the amplitude that rotatablely moves of restriction cover plate 3, the amplitude that cover plate 3 is done rotation can be set at less than 90 degree: minimum angles is that 0 degree (promptly pushing down the state that original copy scans), maximum angle are spent (as 45 degree, 60 degree etc. less than 90, shown in the accompanying drawing frame of broken lines, promptly lift the state that cover plate is changed original copy).
3, can cover plate 3 be fixed on the housing 9 with the hinge 8 that has damping or latching characteristics, in order to improve the stability that cover plate 3 rotates.
More than each embodiment be not to concrete restriction of the present invention, do not breaking away from claims restricted portion of the present invention, can make all concrete modifications to this device.
