If the paper is to be taken after the chest is finished, then the paper is taken and the two sheets of paper are scanned, which will cause the distance between the two papers to be too large: Reliance, so, in the combination of the money roller group and the paper feeding speed, it becomes a _ worthy of attention. Usually take the drive wheel speed of the paper roller group, the secret paper feed roller group parking wheel = take the paper slowly and Wei fast draft, and make the difference between the two speeds of the test 2 ^ == take c to send paper slowly will cause The paper roller group and the paper feed roller =:=: the next, so-to-speed two relative sliding, and such as the I take-up roller group between the parking wheels to form enemy μ, dream *,, the first fold, even lead to paper Tearing, so how to make the speed between the Kawasaki group interfere with each other, and it is an important technical issue to make her bad. Recognize Zhang in the know-how of technology _. The structure of the circle. Use 'U to design the drive wheel of the pickup roller set to a circular or semi-shaped part of the edge / _ 的 of the drive wheel when picking up the paper, the semi-circle of the drive wheel, ', used to contact the paper to take paper After the paper taking operation M308949 is completed, the paper is conveyed by the paper feed roller, and the sulfur parking wheel stops at the non-phase portion toward the paper. Therefore, when the paper feed roller group receives and conveys the paper, the drive wheel of the paper roller 2 is taken. Not in contact with paper. However, this design, because only half of the outer circumference of the wire can be used for paper feeding, so that the paper can transmit a limited distance, so you can only choose to increase the size of the driving wheel to increase the transmission (4), or reduce the paper take-up roller. ^ The lining between the paper feed roller sets, the sewing wheel _ paper feed record, resulting in design restrictions. The driving wheel of the paper take-up roller set designed by the front-loading roller is used to prevent the paper take-up roller group and the paper feed roller group from interfering with each other when the paper feed roller transports the paper. Bearing) or the elastic wire connecting the driving wheel and its power source, that is, the Qian Laida paper feeding roller _, the take-up roller group's active ^de = formation _ state, so that the paper take-up roller group and the paper feed roller group do not interfere with each other: This design has the disadvantages of complicated structure and difficult assembly. ^ ~ [New Content] _ In order to make the paper roll roller group do not interfere with each other, the pick-up roller reduction proposed by Xizhihua has the problems of complicated structure, no spare or limited. In view of the above problems, the purpose of the present invention is to propose a driving wheel transmission mechanism of a paper feeding device, which is simple in structure and easy to produce clothes, and can achieve the combination of the take-up, and the 'roller wheel set and the paper feed roller set. Will interfere with each other. In order to achieve the above object, the present invention proposes a drive wheel drive mechanism of a paper feeding device for driving a drive wheel provided on a shaft, which includes a drive sleeve bushing and a driven block. The M308949 transmission bushing is movably sleeved on the shaft, and has a notch at one end thereof, and a beveled edge is formed in the notch, and the beveled edge forms an inclination angle with the rotation axis. The coupling sleeve is also movably sleeved on the shaft and adjacent to the drive sleeve, the light sleeve has a first-one-way joint end and an actuating end, wherein the actuating end is inserted into the notch and It can be relied on the oblique domain, #带带_ 杂 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴 轴On one side of the recess, the coupling sleeve can be rotated by the rotation of the ## moving sleeve. The driven block is fixed on the shaft and has a second unidirectional light-bonding end, and corresponds to the first-one-way engaging end, and the first single-end end can be unidirectionally combined with the second single ^ The combination of the first one-way facing end is lightly coupled to the second one-way vehicle end in the first direction of rotation, and is separated from the second one-way coupling end in the second direction of rotation in the opposite direction. σ When the drive bushing rotates along the first rotation amount, it can be moved through the beveled edge _ the human car peak moves toward the driven block, so that the first one-way face is combined with the second one-way knowledge, and the light shaft is simultaneously The actuating end of the sleeve will abut against one side of the notch = the first direction of rotation, thereby driving the driven block and the tender turn. When the reading bribe stops rotating and the shaft is still rotated in the first-rotation direction, the rotation direction of the tap is greater than the transmission sleeve, and then the transmission shaft sleeve is rotated on the shaft (four) driven block in the second rotation direction. The first one-way light-closed end plate==_,_ alone, not with the transmission The new type of effect is that the present invention can be applied to the paper take-up roller M308949 group of a paper feeding device 'by means of the paper take-up roller set and the paper feed roller They will not interfere with each other. And this new _ for the conventional technology of the paper roller structure, she has the advantages of splicing and easy assembly. In order to further understand the objects, structures, features, and functions of the present invention, the embodiments are described in detail below. [Embodiment] The driving wheel transmission mechanism disclosed in the present invention is applied to a paper feeding device, and the paper feeding device can be, but is not limited to, a printer, a paper feeding scanner or a multifunction printer. Referring to "FIG. 1" and "FIG. 2", respectively, an external perspective view and a plan view of the present invention are shown. The paper feeding device has a first driving wheel and a first driving wheel 220 in parallel. The first driving wheel 21 () corresponds to the paper picking roller group of the feeding, and the second driving wheel 22 corresponds to the feeding The slave driven roller set, the second driving wheel 210 is used to grab the paper 700 from a paper take-up tray (not shown), and the second drive wheel 220 continues to transmit after the transfer. In general, the second driving wheel will rotate at a higher speed than the first wire wheel 21G, so that the front and rear two buttons form a fixed interval by the difference in rotational speed, and when the leading edge of the paper 700 reaches the second driving wheel 22, The power output to the first driving wheel 210 is stopped. The driving wheel transmission mechanism disclosed in the present invention is used for driving the first driving wheel 210. The first driving wheel 210 is rotated according to the rotation axis, and the first driving wheel is applied to the rotation axis X. To drive the first-active wheel to a pre-M308949 position, the drive wheel transmission mechanism includes a transmission bushing, a ♦ horse-sleeve bushing 5〇〇, and a k-moving block_. The details of the details of each component are as follows: Ming, and Figure 3 and Figure 4 show that the drive bushing 4 is movably sleeved on the shaft 300 for the drive bushing 400. One end forms a beveled edge 'the other end forms a follower portion with respect to the beveled edge 41〇. The beveled edge and the soft axis of the Lai axis - the slanting edge, the edge of the slanting edge of the slanting shaft sleeve 400 extends to form a first urging portion 421, and the beveled edge The axis Χ is toward the end of the drive bushing 400 and forms a second stop 422. A recess 420 is formed between the first stop portion 421 and the second stop portion 422, and the beveled edge 410 is just located in the recess 42. The driven portion 43A can be a gear for connecting to a first power source 92, such as a motor, to allow the transmission sleeve 400 to be driven by the first power source 920. The coupling sleeve 500 is movably sleeved on the shaft 3〇〇, and the coupling sleeve 5 has a first unidirectional coupling end 510 and a coincident end 520. The actuating end 520 forms a protruding block 521 corresponding to the first blocking portion 421, and the actuating end 520 is slidably contacted with the beveled edge 410 by the sliding block 521. When the drive sleeve 400 is rotated in a first rotation direction, the actuation end 520 is slidable relative to the beveled edge 410, and the coupling sleeve 500 is displaced along the rotation axis X away from the transmission sleeve 400, and the first stop block The 421 pushes against the sliding block 521 of the actuating end 520, so that the driving sleeve 400 can drive the coupling sleeve 500 to rotate. When the drive bushing 400 is rotated in one of the reverse directions of rotation, the coupling sleeve 5〇〇 is not pushed. The driven block 600 is fixedly disposed on the 300 shaft rod ′ and the driven block 600 has an M308949 two unidirectional coupling end 620 corresponding to the first unidirectional coupling end 51〇. The first unidirectional coupling end 510 is unidirectionally coupled to the second unidirectional coupling end 62 〇, and the coupling sleeve 500 is coupled to the driven block 6 〇〇 to drive the shaft 3 〇〇 to rotate. Further, the first unidirectional coupling end 510 is coupled to the second unidirectional coupling end 62() in the first rotational direction and out of the second unidirectional coupling end 620 in the first rotational direction of the reverse direction. Therefore, when the coupling sleeve 400 rotates in the first rotation direction, the coupling sleeve 5〇〇 can drive the driven block 6〇〇, and when the coupling sleeve 500 rotates in the second rotation direction, the coupling sleeve 5(8) Will not interlock with the slave _ block _. The coupling sleeve 500 is driven away from the transmission bushing 4 when the transmission car is rotated by the sleeve 4 in the first-rotation direction, and the first one-way end 510 is combined with the second one-way surface. The ends 62 are abutting each other and coupled to each other in the first rotational direction, as shown in "Fig. 4". Please refer to "Figure 5" for reference, and refer to "Figure 2" and "Figure 3" together. Fig. 5 shows the state in which the first driving wheel 21'' and the second driving wheel cooperate with each other. The first power source 920 supplies the driving force of the driven portion 43 to drive the driving sleeve 400 to rotate, and pushes the coupling sleeve 500 to couple the driven block 600, thereby rotating the first driving wheel 210. At this time, the sheet is conveyed by the first driving wheel 21 并 and toward the second driving wheel 220. When the leading edge of the paper 7 is detected by the parallel sensing element 800 and the second driving wheel 220, the second power source 94 输出 immediately outputs the power to drive the second driving wheel 22G to rotate, and the first power source 92 can also be stopped. 〇 Drive transmission bushing 4G0. In the paper feeding device, the second driving wheel 220 as the paper feeding function must have a speed greater than the speed of the first driving wheel of the paper picking function, or when the second driving wheel 22 is in contact with the paper 7 The first power source 92 is stopped. The state of M308949 at this time is that the first driving wheel 210 is driven by the paper 700 and rotates at a speed greater than the speed of the transmission sleeve 4〇〇. Therefore, the driven block _ is relative to the engaging sleeve 500 and the transmission sleeve 400. The second rotation direction is rotated. Therefore, the follower block _ will not be lightly coupled with the face bushing so that its rotational behavior does not interfere with the first power source 92〇, the drive bushing 400, and the face bushing 5〇〇. Therefore, the paper 7 can be fed into the paper feeding device at a speed greater than the paper take-up speed by the second power source 940 and the second driving wheel 22 。. Moreover, since the difference in the degree of continuity of the paper conveyed by the first driving wheel 210 and the second driving wheel 220 can also be transferred to the predetermined interval between the two counties. Although the new preferred embodiment of the present invention is as disclosed above, it is not intended to be limited to the new type of any familiar artisan, in the spirit and model of the new type; the slighter change and refinement' The scope of patent protection shall be subject to the definition of the scope of the patent application attached.
