The paper pick-up mechanism of the conventional automatic feeding device sets a clockwise torsion spring clutch (〇ne way duteh) on its take-up shaft and twists the clutch counterclockwise. When the paper take-up shaft is rotated by the driving force in the clockwise direction, the inner diameter of the twisting clutch is clockwise and the twisting side is generated, so that the frictional force with the recording is increased, and the increased friction is greater than the entire paper take-up. When the torque of the pick-up arm of the mechanism is rotated, the rotational power of the take-up shaft can be transmitted to the pickup arm via the clockwise twister, and then the pick-up is rotated clockwise to contact the paper. On the other hand, when the paper take-up shaft is rotated by the driving force in the counterclockwise direction, the torsion spring clutch moves away from the paper counterclockwise. The inner side is reduced and the m-side is generated, and the fine-grained driving is used to take the rotation. However, the friction mechanism of the inner surface of the torsion spring can be used to increase the frictional force of the inner surface of the torsion spring, and the torque of the paper-pulling arm can be adjusted. Lai Xianglu does not only make 'the manufacturing cost is relatively high, but the paper-feeding mechanism of different specifications must use different twisting degrees, which is quite troublesome. In addition, when the torsion spring is elastically fatigued, the cost of repairing is also higher; The aforementioned one way clutch is a one-way action, so two or more torsion spring clutches are required to achieve the function of bidirectional rotation of the pickup arm.

When the second ratchet engages the first ratchet and drives the first ratchet to rotate, the bump can be simultaneously pushed to make the delay gear Rotate, so as to drive the free end of the paper take-up to perform the paper take-up action. When the paper drives the separation roller to rotate, and at the same time drives the 1342833 to delay the rotation of the gear, since the rotation speed is greater than the rotation speed of the second ratchet, the bump of the gear can be delayed to push the first ratchet to rotate and disengage the second ratchet. The free end of the seat is rotated and reset. After the paper leaves the separation roller, the separation roller loses power and no longer drives the delay gear to rotate.

Here, since the force of the rotation of the first ratchet 4〇f delay gear 3〇 is greater than the force of the elastic member η branch paper take-up seat H), the free end (10) of the paper take-up seat 1 can be driven to rotate around the fixed end. The paper take-up reel 22 is lowered to contact the sheet 9 conveyed by the transfer wheel, and the sheet 9 is conveyed to the separation roller 21 via the pickup roller η. After the paper 9 is driven to the separation roller 21, the separation roller a is rotated by the displacement of the paper 9. Since the rotation speed of the second ratchet 50 is smaller than the rotation speed of the separation roller 21 by the paper 9, the second ratchet is called. 50, the rotation of the first ratchet 40 is no longer driven, and the paper holder 10 can be pushed by the elastic force of the elastic member u, so that the free end 1〇b of the paper take-up seat 1 is rotated and reset around the fixed end 1〇a, and Drive the pickup roller 22 to rise, that is, complete the pickup operation. [Pickup] Power and operation description: The gear 62Λ2/30 and the gear m integrated with the separation roller 21 constitute a return line, and The paper base 10 is a swing arm. The wheel train value e of this wheel train is Z52 Z2J2 7 1342833. P: the rotation speed of the separation roller 21; the rotation speed of the input gear 62; the rotation speed of the π paper take-up seat 10 (swing arm); Ζ62, Ζ52, 厶0, Ζ The number of teeth of the gears 62, 52, 30, and 212, respectively. • State 1: The input gear starts to rotate. At this time, due to the high friction coefficient caused by the contact roller 21 and the paper separation friction plate, the roller does not start to rotate and = 0, and the rotation speed α of the paper holder is taken. ® α 0-α «, —α e(ni -α) = -ο a(e -1) = ent e-1 The speed of the paper take-up is also taken from the paper holder in the same direction as the input gear. The rotation speed 1 is also started as shown in Fig. 2B. • State 2: Φ When the paper is taken successfully, the paper is driven by the pickup roller 22, and the leading edge of the paper enters the nip area between the separation roller and the separation sheet. Since the friction coefficient between the separation roller and the paper is smaller than the coefficient between the separation roller and the separation sheet, the restraint of the separation roller is reduced, so that the rotation β starts to start after the separation roller starts to rotate, and the paper holder is The rotation speed β becomes: nsp~a' e =-r η wide ae (Lnsp-a' a'(el) = eni-nsp 1342833 Also, when the separation roller starts to rotate, the rotation speed a' of the paper holder is smaller than The rotation speed a ^ of the separation roller in the static state before starting the paper picking is also the elastic element u can pull the paper take-up back to its original position when the paper separation roller starts to rotate, as shown in Fig. 2D.

When the first sprung, the first abutting surface buckle abuts against the second abutting surface 511 of the second ratchet 50, whereby the first ratchet 40 can be rotated by the second ratchet (four). When the paper 9 _ The separation roller 21 rotates, and since the rotation speed of the separation roller 21 by the paper 9 is greater than the rotation speed of the second ratchet, the tooth portion of the separation roller is changed. The driving delay gear 30 is rotated instead of rotating by the first ratchet gear ,. At this time, the bump 31 of the delay gear 30 abuts against the limiting groove 42 _ face of the first ratchet 4 (4), thereby driving the first ratchet 4 〇 Rotating, the first inclination of the first-ratchet 40 abuts against the second inclined surface 512' of the second ratchet 5〇 and the first inclined surface 412 moves along the second inclined surface M2 to make the first ratchet of the first ratchet 4〇 The second ratchet 第二 of the second ratchet 5G is engaged with the second ratchet wheel, so that the second ratchet material drives the first ratchet wheel (10) to rotate. When the paper 9 leaves the paper separation wheel and the paper separation wheel stops rotating, the second ratchet wheel 5〇 By rotating, "He is the same, H" I11 again abuts the second: the second abutment (four) of the ratchet 5G, and causes the second ratchet to drive the first =40 rotation. Therefore, the structure of the present invention can be surpassed Please refer to Figure 1, 笫国性* 私八B图 and 4C diagram, in the paper 9 has not been rotated 4〇"^21, the second ratchet 5〇 drives the first-ratchet rotation, and through the first The wall of the ratchet and the bit groove 42 pushes the bump 3 of the delay gear %, so that the delay gear 30 rotates with the rotation of the ratchet 4〇 of the 9 1342833, When the first ratchet 4G drives the delay gear 3G, the other wall surface of the bump limiting groove 42 maintains θ, the angle (as shown in Fig. 3A). When the paper 9 歼° * the paper wheel 2 丨 _, due to the minute 21 Qian Zhang 9 drives the rotation speed to be larger than the first ratchet 5G (10) surface, 嶋W. During the rotation of the object-driven gear 30, the bump 31 produces a θ2 angle circle on its left hand side due to its faster rotation speed. 'and gradually increase with the angle of its rotation 02 until the other side wall of the protrusion 31 abuts the limit groove 42 so that the twist is q, and the left side of the bump 与 and the limit groove produce a &; 角度 angle ( As shown in FIG. 3C, at this time, the bump 31 of the delay gear 3 抵 pushes against the wall surface of the limit groove 42 of the first ratchet * and the ratchet 4Q rotates until the paper 9 is separated from the separation roller η. The paper separation roller 21 is rotated. When the paper 9 leaves the separation roller 21, the separation roller 21 no longer drives the delay gear 30 to rotate, so that the stationary module is continuously driven to drive the second ratchet brother to rotate and drive the first ratchet 4 to rotate, so that the first The wall surface of the limiting groove 42 of the ratchet wheel 40 gradually approaches the bump 31 of the delay gear 30 until the wall surface of the limit groove is again abutted against the convex block 31 of the delay gear 3, and the first ratchet wheel 4 can be again Drive the delay gear % rotation. In the foregoing process, when the paper 9 passes through the separation roller 2, the left side of the projection 31 and the soil surface of the limiting groove 42 generate an e3 angle, and after the paper 9 leaves the separation roller 21, the angle of the & As for the time when the angle of Θ3 is gradually decreasing, the pickup roller 22 does not convey another paper 9 to the separation roller 21', so that the two sheets of paper 9 are opened at the time of conveyance to achieve a delay (deiay). The purpose. The present invention has three functions of picking, _ running, and delay by a relatively simple structure', which not only requires fewer components, but also has the advantages of low manufacturing cost. In addition, the present invention has a longer time for the first ratchet to disengage from the second ratchet 1342833 when the paper to be transported is larger, and the first ratchet and the second ratchet are disengaged for a shorter time when the paper to be transported is smaller. Regardless of the size of the paper to be conveyed, the transfer interval of the two sheets is equal without changing the size of the limit groove, thereby not only improving the convenience of use, but also preparing for different sizes during manufacture. With the _ first - ratchet, effectively increase the ease of preparation. Although the technology of the present invention has been described in the above preferred embodiments, it is not intended to limit the scope of the present invention. Any modifications and refinements made by the spirit of the present invention should be covered by the present invention. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 1342833 [Simple description of the drawings] Fig. 1A is a schematic view showing the appearance of the present invention.
