當自動送紙器２００開始動作時，卡片從自動送紙器２００前端進入。驅動馬達８０正轉通過第一齒輪組５０帶動出紙滾輪３１反轉從而搬送卡片由自動送紙器２００前方開始進入，此時，第一單向傳動齒輪４１處於脫離嚙合的狀態，因此，第一單向傳動齒輪４１不會帶動送紙滾輪軸２２轉動，第二離合齒輪７２被壓伸彈簧７４壓住，故亦不會轉動，故不會帶動第二單向傳動齒輪４２。出紙滾輪軸３２反轉帶動第六傳動齒輪５７反轉從而帶動第一離合齒輪７１正轉，此時由於第一接觸凸部７１１沒有和斜面７３１接觸，因此第一接觸凸部７１１不能推抵單向離合器齒輪７３ ，從而第一離合齒輪７１正向空轉，而不會帶動第二離合齒輪７２轉動，卡片由出紙滾輪軸３２繼續帶動向後進入至送紙滾輪２１處。此時，第一離合齒輪７１仍處於空轉位移內，送紙滾輪軸２２仍不會轉動，而出紙滾輪軸３２繼續帶動卡片向後移動，卡片出現打滑現象，使卡片的後端緣推抵送紙滾輪２１，從而達到矯正卡片歪斜的作用。第一離合齒輪７１空轉位移結束後，第一離合齒輪７１的第一接觸凸部７１１開始推抵單向離合器齒輪７３的斜面７３１，從而帶動第二離合齒輪７２正轉，第二離合齒輪７２嚙合第二單向齒輪４２反轉，帶動送紙滾輪軸２２反轉，帶動第一單向齒輪４１反向空轉，即第一單向齒輪４１反轉時處於空轉狀態，送紙滾輪２１帶動卡片繼續向後搬送直至卡片的後端離開送紙滾輪２１時，驅動馬達８０停止正轉，送紙滾輪軸２２停止反轉。然後，驅動馬達８０開始反轉，通過第一傳動齒輪組５０帶動送紙滾輪２１及出紙滾輪３１正轉從而搬送卡片進行掃描直至掃面完成後從前方排出。When the automatic document feeder 200 starts to operate, the card enters from the front end of the automatic paper feeder 200. The driving motor 80 rotates forward through the first gear set 50 to drive the paper discharge roller 31 to reverse, so that the transport card is started from the front of the automatic paper feeder 200. At this time, the first one-way transmission gear 41 is in a disengaged state, and therefore, the first The one-way transmission gear 41 does not drive the paper feed roller shaft 22 to rotate, and the second clutch gear 72 is pressed by the compression spring 74, so that it does not rotate, so the second one-way transmission gear 42 is not driven. The paper feed roller shaft 32 reversely drives the sixth transmission gear 57 to reverse and drives the first clutch gear 71 to rotate forward. At this time, since the first contact protrusion 711 is not in contact with the slope 731, the first contact protrusion 711 cannot be pushed. The one-way clutch gear 73, so that the first clutch gear 71 is idling forward, does not drive the second clutch gear 72 to rotate, and the card is continuously driven by the paper discharge roller shaft 32 to enter the paper feed roller 21. At this time, the first clutch gear 71 is still in the idle displacement, the paper feed roller shaft 22 still does not rotate, and the paper discharge roller shaft 32 continues to drive the card to move backward, and the card appears to slip, so that the rear end edge of the card is pushed forward. The paper roller 21 is used to correct the skew of the card. After the idle displacement of the first clutch gear 71 is completed, the first contact convex portion 711 of the first clutch gear 71 starts to push against the inclined surface 731 of the one-way clutch gear 73, thereby driving the second clutch gear 72 to rotate forward, and the second clutch gear 72 meshing. The second one-way gear 42 is reversed to drive the paper feed roller shaft 22 to reverse, and the first one-way gear 41 is reversely idling, that is, the first one-way gear 41 is in an idling state when the reverse direction is reversed, and the paper feed roller 21 drives the card to continue. When the conveyance is continued backward until the rear end of the card leaves the paper feed roller 21, the drive motor 80 stops the forward rotation, and the paper feed roller shaft 22 stops the reverse rotation. Then, the drive motor 80 starts to reverse, and the paper feed roller 21 and the paper discharge roller 31 are rotated forward by the first transmission gear set 50 to carry the card for scanning until the scanning surface is completed and discharged from the front.
如上所述，本創作傳動裝置１００藉由第一單向齒輪４１套設於送紙滾輪軸２２一端，第一單向齒輪４１正向單轉，反轉時為空轉，第五傳動齒輪５６固定套設於送紙滾輪軸２２的另一端，第二單向齒輪４２套設與送紙滾輪軸２２的另一端；單向離合器７０設於出紙滾輪軸３２和送紙滾輪軸２２之間，第一離合齒輪７１和固定套設於出紙滾輪軸３２另一端的第六傳動齒輪５７嚙合，第二離合齒輪６２和套設於送紙滾輪軸２２另一端的第二單向齒輪４２嚙合；第一單向齒輪４１單向正轉，反轉是為空轉，第二單向齒輪４２單向反轉，正轉是為空轉。As described above, the present transmission device 100 is sleeved on one end of the paper feed roller shaft 22 by the first one-way gear 41, the first one-way gear 41 is forwardly rotated, the reverse rotation is idle, and the fifth transmission gear 56 is fixed. The other end of the paper feed roller shaft 22 is sleeved on the other end of the paper feed roller shaft 22; the one-way clutch 70 is disposed between the paper discharge roller shaft 32 and the paper feed roller shaft 22, The first clutch gear 71 meshes with the sixth transmission gear 57 fixedly disposed at the other end of the paper discharge roller shaft 32, and the second clutch gear 62 meshes with the second one-way gear 42 sleeved at the other end of the paper feed roller shaft 22; The first one-way gear 41 rotates in one direction, the reverse rotation is idling, the second one-way gear 42 is unidirectionally reversed, and the forward rotation is idling.
因此，驅動馬達８０反轉時，通過第一齒輪組５０傳動，第一單向齒輪４１正轉帶動送紙滾輪２１正轉，出紙滾輪３１正轉，而第五傳動齒輪通過第二齒輪組６０傳動取紙滾輪組１０正轉，亦即送紙滾輪２１正轉，出紙滾輪３１正轉，取紙滾輪組１０正轉，稿紙順利通過掃描。Therefore, when the drive motor 80 is reversed, it is driven by the first gear set 50, the first one-way gear 41 rotates forward to drive the paper feed roller 21 to rotate forward, the paper discharge roller 31 rotates forward, and the fifth transmission gear passes through the second gear set. 60 drive paper take-up roller group 10 rotates forward, that is, the paper feed roller 21 rotates forward, the paper discharge roller 31 rotates forward, the paper take-up roller group 10 rotates forward, and the manuscript paper passes through the scan smoothly.
而當驅動馬達８０正轉時，通過第一齒輪組５０傳動，第一單向齒輪４１反向空轉而不能帶動送紙滾輪２１反轉，出紙滾輪３１反轉，且通過第二齒輪組６０傳動單向離合器７０中的第一離合齒輪７１正轉，將卡片帶入，卡片傳送到靜止不動的送紙滾輪２１處，卡片的後端緣推抵送紙滾輪２１，從而達到矯正卡片歪斜的作用，第一離合齒輪７１正轉完設定距離後，第一離合齒輪７１的第一接觸凸部７１１推抵單向離合器齒輪７３的斜面７３１，而使單向離合器齒輪７３與第二離合齒輪７２嚙合而帶動第二離合齒輪７２正轉，帶動第二單向齒輪４２反轉，帶動送紙滾輪軸２２反轉，帶動第一單向齒輪４１反向空轉，即第一單向齒輪４１反轉時處於空轉狀態，送紙滾輪２１和出紙滾輪３１反轉將卡片搬送至卡片的後端離開送紙滾輪２１時，驅動馬達停止正轉。然後，驅動馬達８０開始反轉，通過第一傳動齒輪組５０帶動送紙滾輪２１及出紙滾輪３１正轉從而搬送卡片進行掃描直至掃面完成後從前方排出。此外，本創作自動送紙器２００的傳動裝置１００一個驅動馬達８０可同時驅動取紙滾輪組１０、送紙滾輪組２０及出紙滾輪組３０，避免使用多個驅動馬達控制，從而節省了成本。When the driving motor 80 rotates forward, the first one-way gear 41 is reversely idling by the first gear set 50, and the paper feed roller 21 cannot be reversed, the paper discharge roller 31 is reversed, and passes through the second gear set 60. The first clutch gear 71 of the transmission one-way clutch 70 rotates forward, the card is brought in, the card is conveyed to the stationary paper feed roller 21, and the rear end edge of the card is pushed against the paper feed roller 21, thereby correcting the skew of the card. After the first clutch gear 71 is rotated by the set distance, the first contact protrusion 711 of the first clutch gear 71 pushes against the inclined surface 731 of the one-way clutch gear 73, and the one-way clutch gear 73 and the second clutch gear 72 are engaged. Engagement causes the second clutch gear 72 to rotate forward, and the second one-way gear 42 is reversed to drive the paper feed roller shaft 22 to reverse, and the first one-way gear 41 is reversely idling, that is, the first one-way gear 41 is reversed. When the idling state is reached, the paper feed roller 21 and the paper discharge roller 31 reversely convey the card to the rear end of the card and leave the paper feed roller 21, and the drive motor stops. Forward. Then, the drive motor 80 starts to reverse, and the paper feed roller 21 and the paper discharge roller 31 are rotated forward by the first transmission gear set 50 to carry the card for scanning until the scanning surface is completed and discharged from the front. In addition, the drive unit 100 of the automatic paper feeder 200 of the present invention can drive the pickup roller set 10, the paper feed roller set 20, and the paper discharge roller set 30 at the same time, thereby avoiding the use of a plurality of drive motor controls, thereby saving cost.
