Description
Technical field
The present invention relates to a kind of paper feedback scanning device, relate in particular to a kind of paper feedback scanning device that utilizes the paper feed power source to do and proofread and correct.
Background technology
When the paper feeding scanner of earliest period is made color or gamma correction, utilize correction paper before scanning, to be fed to the correction foundation that scans in the scanner as standard color or brightness earlier.Yet, proofread and correct paper and lose easily and very not hommization of correcting mode.
In another way, the single scanning line that the scan module of scanner only scans the correction paper that is positioned at scanner inside is used as the correction foundation of standard color or brightness.Yet when this scan line was tarnished, the correction of standard color or brightness foundation was with inaccurate.
In another way, utilize to be different from the motor that drives the paper feed module and gear train and to cooperate the detector of proofreading and correct the position of paper in order to detecting to scan to proofread and correct on the paper multi-strip scanning line with correction foundation as standard color or brightness.When needs are made timing, motor is just changeing correcting sheet is brought into the scope of scanning window.Then, behind scanning multi-strip scanning line, utilize the position of detector detecting correcting sheet, and the counter-rotating of control motor, correcting sheet moved apart the scope of scanning window and to get back to initial position.
In this correcting mode, need motor, gear train, the detector of one group of special use and the control circuit of being correlated with etc., and have more than the number of parts and the high shortcoming of cost.
Summary of the invention
Therefore, one object of the present invention is to provide a kind of paper feedback scanning device that utilizes the paper feed power source to do and proofread and correct, and to reduce the number of motor and control circuit, saves cost.
For reaching above-mentioned purpose, the invention provides a kind of paper feedback scanning device that utilizes the paper feed power source to do and proofread and correct, it comprises scan module, paper feed module, driver module, correcting sheet mobile module and correcting sheet.Scan module is used to the scanning area scanning document, and the paper feed module is passed through scanning area in order to feed documents.Driver module is in order to drive paper feed module and correcting sheet mobile module.Correcting sheet is driven by the correcting sheet mobile module, and can be fed anteposition in scanning area at file, when file just begins to be fed, move apart scanning area gradually so that on the scan module scanning correcting sheet multi-strip scanning line and be fed to that scanning area moved apart scanning area in the past fully so that scan module can be at scanning document subsequently for proofreading and correct usefulness in file.After this driver module counter-rotating, correcting sheet just can move back to scanning area.
Rely on above-mentioned paper feedback scanning device of the present invention, can reach and save cost, shortening correct scan time and dustproof effect.

Embodiment
Fig. 1 to 3 show according to the paper feedback scanning device of preferred embodiment of the present invention first to the three condition schematic diagram.As shown in Figures 1 to 3, the paper feedback scanning device that utilizes the paper feed power source to do and proofread and correct of the present invention comprises scan module 10, paper feed module 20, driver module 30, correcting sheet mobile module 40 and correcting sheet 50.Scan module 10 is arranged in scanning means immovably, in order at scanning area 12 scanning document P.Scan module 10 can comprise a kind of Charged Coupled Device (CCD) transducer or contact image sensor (CIS).Paper feed module 20 is passed through scanning area 12 in order to feed documents P.Usually, paper feed module 20 comprises paper-feed 21, divides the scraps of paper 22 and a plurality of roller 23 to 25.Driver module 30 comprises motor and gear train usually, in order to drive paper feed module 20.In the present embodiment, correcting sheet mobile module 40 is driven by driver module 30.Therefore, driver module 30 drives paper feed module 20 and correcting sheet mobile module 40 simultaneously.
Usually, scan module 10 only need be done the correction of standard color and brightness when the folded file of scanning one.Therefore, when scan module 10 in scanning during subsequent file, correcting sheet 50 continues to be positioned at position shown in Figure 3, after driver module 30 counter-rotatings, correcting sheet 50 just can move back to scanning area 12, returns to state shown in Figure 1.
In order to make correcting sheet 50 can have above-mentioned case of motion, correcting sheet mobile module 40 must have particular design.For example, can utilize friction pulley or ratchet to cooperate relevant mechanism to reach, also can use electromagnetic clutch to reach, be described as follows.
An example of the driver module of Fig. 4 displayed map 1 and correcting sheet mobile module.As shown in Figure 4, correcting sheet mobile module 40 comprises gear 41, and it is driven by the gear 31 of driver module 30.Gear 41 sees through and gets loose/and snap fastener (such as electromagnetic clutch) 42 drives the cylinder coaxial with it 43, and be wound with this correcting sheet 50 on the periphery of cylinder 43.By control get loose/snap fastener 42 so that gear 41 get loose/engage with cylinder 43, can be in order to making no longer shift calibrating sheet 50 of correcting sheet mobile module 40 after moving apart scanning area 12 fully at correcting sheet 50, and after driver module 30 counter-rotatings, make correcting sheet mobile module 40 reverse shift calibrating sheets 50.
In known technology, scanning means is when standby, and correcting sheet is positioned at outside the scanning area; When correct scan, correcting sheet is positioned at scanning area; When scanning document, correcting sheet is positioned at outside the scanning area.Above-mentioned scanning means of the present invention is when standby and correct scan, and correcting sheet is positioned at scanning area, and when scanning document, correcting sheet is positioned at outside the scanning area.With known technology comparatively speaking, the present invention has following advantage:
1. the present invention utilizes the power source that the power of driver module moves as correcting sheet, can save one group of motor, detector and relevant control circuit.
2. the present invention utilizes the paper arrival scanning area time in the past to carry out the action of correct scan, therefore can save the required time of correct scan.
3. correcting sheet of the present invention is positioned at scanning area when standby, therefore can avoid dust to enter scan module or be stained with sticking on the light path of scan module, uses to reach the dustproof effect.
The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to convenient explanation technology contents of the present invention, rather than with narrow sense of the present invention be limited to the foregoing description, in the situation that does not exceed spirit of the present invention and claim, the many variations of being done is implemented, and all belongs to the scope of the invention.
