Description
Technical field
The invention belongs to scanning device field, be specifically related to after a kind of paper by required scanning puts into, the efficient scanner scanned to be carried out one by one.
Background technology
Scanner is that one utilizes photoelectric technology and digital processing technology, with scan mode, figure or image information is converted to the computer entry device of digital signal.Scanner has good scanning effect to page of text, drawing, by the middle of its scanning t test to character image process software, can remove the trouble of typewriting again from, and can modify to image very easily.Therefore scanner is widely used in office.
In existing office, when paper document is scanned, usually scan one by one; Scanner is opened, first is put into and scans, again by first taking-up after having scanned, second has been put into and scans, the like.Once scanning amount is comparatively large, then required sweep time is longer, takies human time also corresponding longer, reduces office efficiency.
Therefore, developing a kind of efficient scanner that can carry out rapid scanning one by one to more paper document is those skilled in the art institute urgent need to solve the problem.
Summary of the invention
For solving the problem, the invention discloses a kind of efficient scanner that can carry out rapid scanning one by one to more paper document.
In order to achieve the above object, the invention provides following technical scheme:
A kind of efficient scanner, comprises paper feed separator and scanning means; Paper feed separator comprises paper feed separating table, upper paper feed is separated wheel and lower paper feed is separated wheel; The upper surface of paper feed separating table is provided with groove; Lower paper feed is separated wheel and is connected in the groove of paper feed separating table by rotating shaft uniform rotation; And the axial restraint that lower paper feed is separated wheel is provided with lower driving wheel; Lower driving wheel is connected by chain, and wherein any one lower driving wheel is also connected with lower driving wheel motor; Upper paper feed is separated wheel and is horizontally placed on by connecting rod the top that lower paper feed is separated wheel; And the axial restraint that upper paper feed is separated wheel is provided with upper driving wheel; Upper driving wheel is connected by chain, and wherein any one upper driving wheel is also connected with upper driving wheel motor; Scanning means comprises scan table, scanning board and transducer; The upper surface that surface and the lower paper feed of scan table are separated wheel is mutually concordant; The surface of scan table is set to transparent, and the below on its surface is provided with lighting device; Transducer is fixed on scan table is separated wheel one end top near lower paper feed; Scanning board and elevating lever fix; Elevating lever is connected with transducer.
The invention provides a kind of efficient scanner, be made up of paper feed separator and scanning means.
Paper feed separator in the present invention is separated wheel by paper feed separating table, upper paper feed and lower paper feed separation wheel forms.The upper surface of paper feed separating table is provided with groove; Lower paper feed is separated wheel and is connected in the middle of groove by axis of rotation, and the axial restraint that lower paper feed is separated wheel has lower driving wheel, and lower driving wheel is connected by chain, and wherein any one lower driving wheel is also connected with lower driving wheel motor.This structure makes evenly distributed lower paper feed be separated wheel can under the drive of underdrive motor, and maintenance operates simultaneously.In the same manner, lower paper feed is separated wheel and is horizontally arranged in by connecting rod the top that lower paper feed is separated wheel, and is axially installed with upper driving wheel; Upper driving wheel is connected by chain, and wherein any one upper driving wheel is also connected with upper driving motor.This structure makes paper feed be separated wheel can under the drive of upper driving motor, and maintenance operates simultaneously.
If the rotating speed of upper driving motor to be adjusted to the rotating speed being greater than underdrive motor, to be then separated the translational speed of taking turns the top paper contacted with upper paper feed and will to be greater than and to be separated the translational speed of taking turns the bottom paper contacted with lower paper feed; Speed difference between top paper with bottom paper will impel top paper to be separated with bottom paper, the last paper to be scanned that just batch paper to be scanned can be split as individual.
Scanning means in the present invention is made up of scan table, scanning board and transducer.The upper surface that surface and the lower paper feed of scan table are separated wheel is mutually concordant, and the paper after making to be separated can arrive on the scan table of equal altitudes.The surface of scan table is set to transparent, and the below on its surface is provided with lighting device; Transducer is fixed on scan table is separated wheel one end top near lower paper feed; Scanning board and elevating lever fix; Elevating lever is connected with transducer.This structure makes when individual paper document arrives below transducer, and transducer can be responded to individual paper document on scan table surface, sends signal subsequently to elevating lever, and control elevating lever drives scanning board to move to paper document place and scans.
As preferably, upper driving wheel motor and lower driving wheel motor are servomotor, and are connected to servo drive; Servo drive is also connected with transducer.
Upper driving wheel motor in the present invention and lower driving wheel motor are all chosen as servomotor, and are connected with servo drive, and servo drive is connected with transducer.This is arranged so that the present invention can control the unlatching of paper feed, closedown and paper feeding speed by transducer.When first transducer detects the front end of individual paper document, and when the rear end of individual paper document being detected subsequently, by servo drive, servomotor cuts out, make the present invention have the sufficient time to scan individual paper document; Open servomotor more subsequently, carry out paper feed, scanning.
As preferably, scan table is also provided with the paper feed plate of arcuation near one end that lower paper feed is separated wheel; Paper feed plate is bent downwardly.
Because paper document is softer, paper document is exceeded time last lower paper feed is separated wheel can be bent downwardly, cause possibly cannot arriving on scan table, therefore one end place that the present invention is separated wheel at scan table near lower paper feed is provided with reclinate arcuation paper feed plate, make reclinate paper document can arrive on paper feed plate, add the paper feed effect of paper feed separator, make paper document can be pushed on scan table.
As preferably, upper paper feed is separated the surface that wheel and lower paper feed be separated wheel and is all enclosed with rubber ring.
The surface that the present invention is separated wheel and lower paper feed separation wheel at upper paper feed is all enclosed with rubber ring, paper feed separation wheel and lower paper feed is made to be separated wheel when rotating, larger frictional force can be produced, in drive paper feed be separated wheel and lower paper feed be separated paper document between wheel can stably forwards transportation, make the present invention more efficient when carrying out paper and being separated.
As preferably, transducer is light sensor.
Transducer in the present invention is chosen as light sensor; Light sensor can be responded to the illumination that the lighting device of scan table lower face produces.When there being scan table surface not have paper document, the illumination experienced is stronger; And when scan table surface have paper document by time, illumination is more weak, can judge that paper document arrives scan table surface condition thus.
The present invention is compared with existing scanner, and beneficial effect is: only paper document need be put into paper feed separator when (1) uses and just can complete and scan one by one, simple to operate; (2) scan efficiency is high, reduces the consumption of human resources, promotes office efficiency; (3) structure is simple, for ease of maintenaince.
