Description

Two-sided full-automatic inlet device

Technical field

The utility model relates to a kind of two-sided full-automatic inlet device, refer to especially a kind of when can be used for scanning double-side formula file, the action that file need not be refunded, speed is very fast, gets paper and puts paper full-automatic inlet device comparatively easily.

Background technology

Scanner has become one of basic outfit of many computing machine users gradually, no matter be that literal or figure can be put scanner into, allow computing machine verily according to reading into, the principle of scanner is very simple in fact, utilize the light shot file exactly, read then and reflect or light that transmission is come, just can obtain this image partly.In addition, the image that scanning is good also can read in image processing software to be repaired, if scanning is file, also can utilizes " character recognition software " that file is become archives and exist in the computing machine.

For scanning double-side formula file, existing on the market multiple two plane type image scanner arises at the historic moment, and as shown in Figure 1, is known " two plane type image scan mechanism ", comprises a paper-advance unit 10a; One paper extraction unit 11a is positioned at the same side of this paper-advance unit 10a; One scan district 12a, be file line inbound path 13a with connection this paper-advance unit 10a and this paper extraction unit 11a, reach this scanning area 12a and comprise a transparency window 14a, and direction control roller 15a, this direction control roller 15a is positioned at the relative side of this transparency window 14a; Single-revolution device 16a, have an input path and an outgoing route, connect scanning area 12a respectively, this input path is in order to the file that scan one side of guiding from this scanning area 12a, this outgoing route to another side, and guides file after this counter-rotating to this scanning area 12a in order to this file that has scanned one side that reverses; One induction installation 17a is positioned at the paper delivery end of this turning gear 16a, when withdrawing from this turning gear 16a at this document, transmit a direction control signal to this direction control roller 15a so that this direction control roller 15a with counter-rotation; An and image fetch device 18a, it is the outside that is positioned at this transparency window 14a, in order at this document progressively from this paper-advance unit 10a when this transparency window 14a, read the image of first of this document, and this document progressively self-rototing device 16a read the image of second of this document when this transparency window 14a.

Just, above-mentioned known two plane type scanning mechanism, its paper extraction unit 11a is positioned at the same side of paper-advance unit 10a, after file is imported by paper-advance unit 10a, need refund the paper extraction unit 11a output file of the same side, so the file fed distance is longer, needs the long time of cost just can finish scanning.

In addition, known two-sided scanning mechanism, its paper-advance unit 10a and paper extraction unit 11a are positioned at the same side, and be skewed or horizontal setting, when file is inserted paper-advance unit 10a and is exported paper extraction unit 11a to, because paper-advance unit and paper extraction unit design for levels, need move forward into paper apparatus and just can take out the file that lower floor's scanning is finished, make and get paper and put inconvenience of paper.

As from the foregoing, above-mentioned known two-sided scanning mechanism on reality is used, obviously has inconvenience and exists with defective, remains to be improved.

So the utility model people is thoughts on the property improved of above-mentioned defective, be that the spy concentrates on studies and cooperates theoretical utilization, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.

Summary of the invention

Main purpose of the present utility model provides a kind of two-sided full-automatic inlet device, file when making duplex scanning, the not action that need refund, the file delivery speed is more very fast than general two-sided scanning mechanism.

Another purpose of the present utility model provides a kind of two-sided full-automatic inlet device, when file is inserted the paper feed unit, can utilize gravity to align automatically; And the paper feed unit with get two sides that the paper unit is positioned at full-automatic inlet device, make get paper and put paper comparatively convenient.

In order to realize above-mentioned purpose, the utility model provides a kind of two-sided full-automatic inlet device, includes a paper feed unit; One gets the paper unit, and it is arranged at relative two sides with this paper feed unit; The one scan district, it has this paper feed unit of connection and this gets the file line inbound path of paper unit, and this document travel path is provided with a plurality of in order to file is delivered to the roller of getting the paper unit by the paper feed unit; And a leaf turner, it is arranged between this document travel path, can be driven switching position, in order to leader files page turning in this document travel path.

Aforesaid two-sided full-automatic inlet device, paper feed unit have one in order to hold first space of file to be scanned, are one to be and to erect the microscler space that shape is provided with, and the bottom is provided with a guide ramp in order to leader files input scan district.

Aforesaid two-sided full-automatic inlet device is got the paper unit and is had one in order to hold second space that file is finished in scanning, also is and erects the microscler space that shape is provided with.

Aforesaid two-sided full-automatic inlet device, the file line inbound path of scanning area is divided into one first section, one second section and one the 3rd section, leaf turner has one first guiding face and one second guiding face, first guiding face is connected between first section and second section, and second guiding face is connected between second section and the 3rd section.

Aforesaid two-sided full-automatic inlet device, described scanning area is provided with one first transparency window and one second transparency window, described first transparency window and second transparency window are positioned at the file line inbound path outside, are provided with first scanning position and second scanning position that berths for processing equipment with transparency window corresponding file travel path outer lower portion.
