The actuating device 100 of described automatic sheet feeder also includes by driving the drive gear set 50 that motor 90 drives, one first gear train 70,1 second gear train 60 and one the 3rd gear train 80 driven by drive gear set 50.
Described drive gear set 50 is in pickup roller group 10 and goes out between paper roller group 30 and by driving motor 90 to drive.Specifically, drive gear set 50 includes driving gear 51 and one first feed belt 52 being connected to drive motor 90.Drive gear set 50 is used for driving the first gear train the 70, second gear train 60 and the 3rd gear train 80.
Second gear train 60 includes being respectively sleeved at paper delivery roller shaft 32 or paper pushing roller axle 22 and contrary the first one-way transmission gear 61 and the second one-way transmission gear 64 of rotation direction, and the first one-way transmission gear 61 and the second one-way transmission gear 64 are all the roller shaft of unidirectional drive paper delivery in the same direction 32 or paper pushing roller axle 22.Specifically, second gear train 60 also includes one first travelling gear 62 and the second travelling gear 63 engaged with the first travelling gear 62, first one-way transmission gear 61 engages the first travelling gear 62, first travelling gear 62 engages the second travelling gear 63, and the second travelling gear 63 engages the second one-way transmission gear 64.First feed belt 52 is connected to drive between gear 51 and the first one-way transmission gear 61.Second gear train 60 is arranged at paper pushing roller axle 22 one end.
Described first gear train 70 is used for driving pickup roller group 10, and when drive gear set 50 rotation direction difference, the first gear train 70 drives pickup roller group 10 to produce different rotation directions.Specifically, first gear train 70 include one first take paper travelling gear 71, take with first paper travelling gear 71 engage and fixing with pickup roller group 10 be connected second take paper travelling gear 72 and one second feed belt 73, the second feed belt 73 is connected to first and takes between paper travelling gear 71 and the first one-way transmission gear 61.Second takes paper travelling gear 72 is fixedly connected on comber axle 15.
Described 3rd gear train 80 connects paper delivery roller shaft 32 and paper pushing roller axle 22 and transmits driving torque.3rd gear train 80 includes that the 3rd travelling gear 81, being fixedly connected on paper pushing roller axle 22 other end is fixedly connected on the 4th travelling gear 82 and the 3rd feed belt 83 being connected between the 3rd travelling gear 81 and the 4th travelling gear 82 of paper delivery roller shaft 32 one end.
Drive the motor 90 can two-way drive drive gear set 50, when drive gear set 50 rotation direction difference, first gear train 70 drives pickup roller group 10 to produce different rotation directions, and first one-way transmission gear the 61, second one-way transmission gear 64 drives paper delivery roller shaft 32 or paper pushing roller axle 22 to turn in the same direction respectively.
The motion flow that the actuating device 100 of this utility model automatic sheet feeder and automatic sheet feeder carry out single-sweep is as follows:
When automatic sheet feeder starts action, contribution is positioned in feeding box 41.Driving motor 90 to rotate forward drives driving gear 51 to rotate forward, gear 51 is driven to drive the first ratchet 61 to rotate forward by the first driving belt 52, first one-way transmission gear 61 drives first to take paper travelling gear 71 by the second feed belt 73 again and rotates forward, take paper travelling gear 71 by first to engage second and take paper travelling gear 72, first takes paper travelling gear 71 drives second to take paper travelling gear 72 to invert, thus drive pickup roller group 10 to press for 41 times towards feeding box, and paper-feed 11 and comber 13 is driven to invert and sent in paper feed channel 42 by contribution.Simultaneously, first one-way transmission gear 61 drives paper pushing roller 21 to rotate forward thus is continued to be fed into by contribution and in scan channel 43 be scanned contribution and the contribution after scanning is sent into paper delivery passage 44, the first one-way transmission gear 61 and the second travelling gear 63 is engaged by the first travelling gear 62, first one-way transmission gear 61 drives the second travelling gear 63 to rotate forward, thus drive the second one-way transmission gear 64 to invert, being one-directional rotation gear by the second one-way transmission gear 64, the second one-way transmission gear 64 cannot drive paper pushing roller axle 22 to rotate；First one-way transmission gear 61 drives paper pushing roller axle 22 to rotate forward thus drives the 3rd travelling gear 81 to rotate forward, by the 3rd feed belt 83,3rd travelling gear 81 drives the 4th travelling gear 82 to rotate forward, 4th travelling gear 82 drives paper delivery roller shaft 32 thus drives out paper roller 31 to rotate forward, going out paper roller 31 and continue to send contribution paper delivery passage 44, contribution has scanned.
When user wants to cancel contribution scanning, press the cancel key on automatic sheet feeder, driving motor 90 reversion to drive drives gear 51 to invert, gear 51 is driven to drive the first ratchet 61 to invert, first one-way transmission gear 61 drives first to take paper travelling gear 71 by the second feed belt 73 and inverts, first takes paper travelling gear 71 drives second to take paper travelling gear 72 to rotate forward, thus drives pickup roller group 10 upwards to raise, and will not push down contribution.Now, because the first one-way transmission gear 61 belongs to one-directional rotation gear, paper pushing roller axle 22 can not be driven to rotate, first one-way transmission gear 61 drives the second one-way transmission gear 64 to rotate forward by the first travelling gear 62 and the second travelling gear 63, second one-way transmission gear 64 drives paper pushing roller axle 22 to rotate forward, paper pushing roller 21 rotates forward thus contribution is sent into scan channel 43, and paper pushing roller axle 22 drives the 3rd travelling gear 81 to rotate forward and driven the 4th travelling gear 82 to rotate forward by the 3rd feed belt 83 thus continued contribution to send paper delivery passage 44 again.
In sum, the actuating device 100 of this utility model automatic sheet feeder can be simultaneously driven pickup roller group 10, paper pushing roller group 20 by a driving motor 90 and be gone out paper roller group 30, motor 90 is driven to drive motor 90 to invert when rotating forward or cancel scanning when no matter scanning, drive motor 90 all can drive paper pushing roller 21 and go out paper roller 31 and rotate in one direction, i.e. rotate forward the direction that contribution is sent automatic sheet feeder, thus user need not uncap and makees paper eliminating action and decrease cost when cancelling scanning motion.
