And a second roller 41 corresponding to the first roller u and extending from the opening 27 to the outside of the bottom plate 23, a second gear 42 axially coupled to the side of the second roller 41, Contrary to the second gear 42 and axially coupled to the other side of the second roller 41, the convex tube 43 and a shaft hole 44 which is disposed in the axial direction and penetrates. The convex tube 43 is permeable to the side plate 21 of the swing arm unit 20 and extends to the outside of the side plate 21. In the present embodiment, the transmission element 5G is an idler that is drawn in the middle portion of the swing arm unit 2G and is sprayed between the first and second gears 12 and 42. Therefore, the transmission member 50 may be any mechanism that can transmit the power of the drive shaft member 10 to the pickup shaft member 4G, for example, a belt. The first gear unit 60 has a linkage shaft member 61 which is rotatably shafted in the hole 44 of the paper take-up shaft member 40, and two of which are respectively fixed at the two ends of the linkage pumping member 6 and located at the swing arm The load-claw 62 on the outer side of the unit 20 and the overload-protecting elastic element disposed between the paper take-up shaft member 40 and the interlocking shaft member 61 8 200821169 = the home piece 61 has a positioning beam opposite to the convex tube 43 The "claws 62" each have a positioning end portion 621 fixed to the interlocking shaft member 61, ???, the oscillating end portion 622 of the positioning end portion 621 is oppositely disposed, and a locating end portion extends to the oscillating material 622 and facing the blocking surface 623 of the direction X, the overload protection elastic member 63 is a coil spring, and the opposite ends are respectively frictionally bundled on the convex tube 43 and the positioning sleeve 6 ι. 3, FIG. 5 and FIG. 6 shows a paper-drawing diagram, when the drive shaft member 1 is driven to rotate in one direction (clockwise direction as shown in FIG. 6), the first roller is driven. U and the first gear are rotated to generate frictional friction between the retaining edge 311 and the side plate by the friction member 30, The frictional damping is converted into a torsion force, and the swinging portion 25 of the swing arm unit 20 is pivoted with the pivotal portion 24 as a pivoting center, and the pick-up shaft member 40 is also slid along with the drive shaft member. Rotating clockwise' and utilizing the two ends of the overload protection elastic member 63 and the flange 43 疋f sleeve 611 to generate a friction band, the rotational power of the paper take-up shaft member is transmitted through the overload protection elastic member 63 Linking the shaft member 61 and the pawl 62 to the stopping unit 6〇, and causing the claws 62 to swing to a paper stop position (see FIG. 6), and when the claws 62 are in the paper blocking position, The end edges of the swinging end portions 622 of the claws 62 are abutted on the paper feed tray ιι, and the bottom edge of the second roller 41 of the paper take-up shaft member 40 forms a maximum height with the paper feed tray 11 H, and the angle 623 between the blocking surface 623 of the claw 62 and the paper feed tray 110 is about 53 degrees, and the maximum height H is used for the user to easily place the paper on the paper feed tray 11 And using the angle 0 between the stop surface 623 and the paper feed tray 11〇, the front end of the paper can be tilted 9 200821169 — Shape, that is, a slight distance between the paper and the paper, the mouth effectively reduces the incidence of multiple feeds. Figure 3 and Figure 7 shows a schematic diagram of the paper take-up action when the drive shaft When the driving is rotated in the counterclockwise direction, the first roller is driven to rotate the first gear 12, and the friction member 3 〇 is abutted between the retaining edge and the side plate 21 to generate frictional damping. And the frictional damping is converted into a force, which causes the swinging portion 25 of the swing arm unit 2 to pivot downward with the pivotal portion _ 24 as a pivoting center, and the second roller 41 is pressed down. On the paper, the second and a rollers 41 and u are simultaneously rotated to complete the paper take-up operation. At this time, the power of the paper take-up shaft member 4〇 is transmitted to the interlocking shaft member 61 and the claws 62 through the overload protection elastic member 63, and the claws 62 can be swung by the paper stop position. In the collapsed position, when the pawls are in the stowed position, the swinging end portion 622 of the pawl 62 abuts against the drive shaft member 10. Although the driving shaft member 10 is continuously driven to rotate, since the arc retaining claws 62 have been restrained from being locked on the driving shaft member 1〇, the setting of the overload protecting elastic member 63 is caused by the torque overload. The paper take-up shaft member 4 is idling with respect to the interlocking shaft member 61, and the paper can be continuously taken. Therefore, the paper feeding device of the present invention has the functions of facilitating paper feeding and automatic paper picking', and when placing paper, it is not necessary to forcefully press the paper feeding tray 5' as conventionally and the front end of the paper receives the claws. The blocking of 62 can produce the effect of accurate positioning 'and the angle between the stop surface of the claws 62 and the paper feed tray Π0 can make the front end of the paper form a slope, which can effectively reduce the incidence of multiple sheets. . 10 200821169 The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple scope of the invention and the content of the invention. Both effect changes and modifications are still within the scope of the invention patent.
