Description
The utility model relates to the automatic carriage of device of image scanning.
Existing paper advance mechanism is as shown in Figure 1: it has a contribution to be taken into roller set 1, a paper feed guide plate 2, one scan roller 3, a curved arc shape guide plate 4, an end guide plate 5, body guide plate 61,62, a light transmission piece 71, an Image sensor apparatus 7, a paper delivery guide plate 8 and a contribution to send roller set 9.Contribution is taken into roller set 1 to be made up of active roller 11, return idler 12, in order to manuscript to be scanned 10 is taken into by the relative rotation of active roller 11, return idler 12; Paper feed guide plate 2 is by last lateral paper guide 21, down lateral paper guide 22 is separated by one at interval and constitute a paper guide, and guiding is taken into the contribution that roller set 1 is sent into by contribution; Scanning roller 3 is positioned at paper feed guide plate 2 rear ends; Curved arc shape guide plate 4 overlays on the outer wheel face of scanning roller 4 and forms a curved arc shape and leads, and is scanned contribution with guiding and advances; Under scanning roller 4 end guide plate 5 is arranged, it comprises a top rake section 51, a horizontal section 52 and a rear-inclined section 53; Forward and backward angled section 51,53 is corresponding with body guide plate 61,62 respectively, the light transmission piece 71 and horizontal section 52 belows are separated by; The zone of horizontal section 52 belows is scanning area or claims the scanning window; The guide groove that forms between end guide plate 5, body guide plate 61,62 and the light transmission piece 71 can be scanned contribution in order to guiding and be passed through scanning area; Image sensor apparatus; The existing sensing element of employing also is positioned under the horizontal zone 52, is to be separated with light transmission piece 71, glass sheet 72 therebetween; Paper delivery guide plate 8 is made of upper and lower lateral paper guide 81,82, to draw scanned contribution; Paper delivery guide plate 8 rear ends are that contribution is sent roller set 9, and it is made up of active roller 91, return idler 92, in order to scanned contribution is rotated relatively by it and send; Scanning roller 3 peripheries have a plurality of auxiliary wheels 31,32,33, auxiliary wheel 31 is on 4 on paper feed guide plate 2 and curved arc shape guide plate, auxiliary wheel 32 is on 5 on curved arc shape guide plate 4 and end guide plate, auxiliary wheel 33 is on 8 on end guide plate 5 and paper delivery guide plate, and each auxiliary wheel wheel face all is attached to scanning roller 3 wheel faces.
Shown in Fig. 2-7: illustrate that there is the bad problem of quality of scanning in existing paper advance mechanism in the image scan practical operation.Fig. 2 when contribution 10 front ends are normal in auxiliary wheel 33 fashion, but when entering and scanning 3 on roller, because of contribution 10 must have tension force, could pass through, and causes irregularity, disturbing phenomenon as Fig. 3; Fig. 4 recovers normal again when contribution 10 is pressed from both sides toward paper feeding by auxiliary wheel 33 with scanning roller 3; Fig. 5 is when contribution 10 rear ends break away from auxiliary when rolling 32, still normal; But after contribution 10 rear ends break away from auxiliary wheel 32, because the paper rigidity, contribution 10 is changed to another path (dotted line) just disturbance occurs according to original route (solid line) as Fig. 6; Then break away from auxiliary wheel 32 as Fig. 7 contribution 10 and stablize normally again to body guide plate 61 walls, this phenomenon certainly will influence quality of scanning as not solving.
The purpose of this utility model just provides a kind of device of image scanning that is used for, and can prevent the rule equipment of the automatic sheet feeder scan-image disturbance of disturbance.
The purpose of this utility model is achieved in that the rule equipment of automatic sheet feeder scan-image disturbance, it comprises a paper feed guide plate, the one scan roller, one end guide plate, one Image sensor apparatus and a paper delivery guide plate, end guide plate is positioned under the scanning roller, it has a top rake section, one horizontal section and a rear-inclined section, and the zone of horizontal section below is promptly as a manuscript to be scanned during by this scanning area, scan the scanning area of this contribution by this Image sensor apparatus, it is characterized in that: the horizontal section bottom surface of this end guide plate is provided with a disturbance and advises positive mechanism, and this disturbance is advised positive mechanism and convexedly stretched in the horizontal zone below of end guide plate and have with pressure and press an attached height by this scanning area contribution.
Above-mentioned design, the setting of positive mechanism is advised in disturbance by this, and according to test, it is smooth-going stable that advancing of this contribution is able to, and reached the effect that prevents disturbance.
Below by accompanying drawing, embodiment the utility model is described further again.
