Abstract
The present invention relates to a movable corrector for a paper feeding scanner, which comprises a correcting sheet and a cam. The correcting sheet is used for a scanning module to scan an image on the correcting sheet for correction. The cam is driven to rotate by a motor and is used for driving the correcting sheet to move so as to enter or quit a scan window of the scanning module. The motor can make the correcting sheet quit the scan window when the motor does not need to rotate reversely.
Description
Technical field
The present invention relates to a kind of portable means for correcting of paper feeding scanner, particularly a kind of cam that utilizes drives the means for correcting of proofreading and correct the correcting sheet of usefulness for paper feeding scanner.
Background technology
Fig. 1 and 2 is a kind of means for correcting schematic diagram of existing paper feeding scanner.Shown in Fig. 1 and 2, in this means for correcting, motor 114 drives cylinder 112 rotations, is wound with correcting sheet 116 on the cylinder 112.By the clockwise direction or the anticlockwise rotation of cylinder 112, correcting sheet 116 can be pushed into scan module 110 belows, or correcting sheet 116 is moved apart scan module 110 belows.For fear of error accumulation, a detector 118 must be set, whether moved apart scan module 110 belows with detecting correcting sheet 116.
Therefore, traditional correcting mode, be to utilize a detector, reversing motor and gear train, to rotatablely move by thin slice (Mylar) correcting sheet and to convert rectilinear motion to, the scanning window that makes correcting sheet can move to scan module when needed carries out corrective action, retreats on one side behind to be corrected the finishing again.
Yet soft thin slice can't convert rectilinear motion stably exactly with rotatablely moving to.May cause correcting sheet alignment correction sheet correctly thus, thus the effect correction effect.In addition, utilize detector and motor that can two-way rotation to realize that correcting sheet " enters " the action complexity that reaches " withdrawing from " scanning window, and can't effectively reduce cost.
Summary of the invention
An object of the present invention is to provide a kind of cam that utilizes and drive the means for correcting of proofreading and correct the correcting sheet of usefulness for paper feeding scanner, wherein the motor in order to driving cam need not counter-rotating, can allow correcting sheet withdraw from the scanning window of scan module.
For achieving the above object, the invention provides a kind of portable means for correcting of paper feeding scanner, it comprises a correcting sheet and a cam.Correcting sheet uses the image that scans on it for the one scan module to use for proofreading and correct.Cam is rotated by a motor driven, in order to drive that correcting sheet moves and the one scan window that enters or withdraw from scan module.
Cam can be a kind of external form closed type (Form-closed) cam or a kind of external force closed type (Force-closed) cam.Correcting sheet can directly contact with cam, or be installed on one with driven member that cam directly contacts on, provide stable correction quality with this.

Embodiment
Fig. 3 and 4 is the portable means for correcting schematic diagram of paper feeding scanner in the first embodiment of the invention.As shown in Figure 3, the portable means for correcting of the paper feeding scanner of present embodiment comprises a correcting sheet 11 and a cam 12.Scan module 10 supplies to proofread and correct the image of usefulness on scanning correcting sheet 11.Present embodiment cam 12 is an eccentric wheel, and it is subjected to a motor 16 to drive rotation, in order to drive that correcting sheet 11 moves and the one scan window 30 that enters or withdraw from scan module 10.Correcting sheet 11 directly contacts with cam 12 as a driven member.Cam 12 is a kind of external force closed type (Force-closed) cams, so elasticity of demand assembly (such as spring) 13 is connected to correcting sheet 11 and scan module 10.Scan module 10 is actionless, when therefore correcting sheet 11 moves to the below (scanning window 30) of scan module 10, can elasticity of compression assembly 13 with storage power,, when correcting sheet 11 need withdraw from scanning window, provide to make correcting sheet 11 return to the restoring force of state shown in Figure 3 with this.
In other embodiments, cam 12 also can be a kind of external form closed type (Form-closed) cam, just need not elastic parts for this cam restoring force is provided.
For correcting sheet 11 can steadily be moved along single direction, this means for correcting can also comprise the moving direction that a guiding mechanism 15 comes bootstrap correction sheet 11.
Fig. 5 and 6 is the portable means for correcting schematic diagram of paper feeding scanner in the second embodiment of the invention.The present embodiment and first embodiment are similar, and difference is that elastic parts 14 is connected to a housing 20 of correcting sheet 11 and paper feeding scanner.Housing 20 all is actionless with scan module 10, so can be used to make elastic parts 14 to store and release energy, makes correcting sheet 11 enter or withdraw from the effect of scanning window with realization.
Fig. 7 and 8 is the portable means for correcting schematic diagram of paper feeding scanner in the third embodiment of the invention.The present embodiment and first embodiment are similar, and difference is that this means for correcting also comprises a driven member 21 that contacts with cam 12, and correcting sheet 22 is installed in the above.Elastic parts 23 is connected to driven member 21 and scan module 10.Usually correcting sheet is made by thin slice (Mylar) assembly, so can't provide enough intensity to resist the push-and-pull of elastic parts 23 and cam 12 sometimes.Guiding mechanism 25 is in order to the moving direction of guiding driven member 21, thus the moving direction of bootstrap correction sheet 22.
Fig. 9 and 10 is the schematic diagram of the portable means for correcting of paper feeding scanner in the fourth embodiment of the invention.Present embodiment and the 3rd embodiment are similar, and difference is that elastic parts 24 is connected to a housing 20 of driven member 21 and paper feeding scanner.
Therefore, the present invention utilizes cam to rotatablely move to be converted to rectilinear motion stably, obtains preferable calibration result thereby guarantee with this that correcting sheet can correctly be focused.For example, when cam rotates to 180 when spending from 0 degree, rotatablely moving of motor promptly is converted to rectilinear motion by cam, whereby correcting sheet pushed scanning window; When cam rotates to 360 when spending from 180 degree, the elastic restoring force by an elastic parts shifts out scanning window with correcting sheet.Therefore, motor need not to have reverse function, and this means for correcting need not to use detector to detect the position of correcting sheet.Thus, motor whenever circles (360 degree), can finish the action that correcting sheet is entered and withdraw from scanning window, and is all quite convenient in use and the design.In addition, the present invention need not to adopt soft thin slice, and can adopt the correcting sheet of hard, therefore can solve the unmanageable flexible shortcoming of thin slice in the prior art.
More than be preferred embodiment of the present invention and design, this preferred embodiment and design only illustrate, be not to be used to limit the scope of the invention, all with the technological means that is equal to or any distortion in the scope that claim was contained, all do not break away from interest field of the present invention and category thereof.
