The first axle tube 13 has a retaining edge 13ι . The swing arm unit 20 has two opposite side plates 21, two end plates 22 connected between the side plates 21, and a bottom plate 23 connected to a top edge of the side plates 21 and the end plates 22, through which the sides are The plate 212 and the shaft pivot portion 24 disposed on the drive shaft member 10, a swinging portion 25 disposed opposite the shaft pivot portion 24, and an intermediate portion between the shaft pivot portion 24 and the swing portion And 1302499 - an opening 27 formed in the bottom plate 23, the side plate 2i having a second shaft tube 211 opposite to the first shaft tube 13, the first roller extending from the opening 27 to the bottom plate 23 external. The friction member 30 is exemplified by a compression spring, and the two ends are respectively sleeved on the outside of the first and second shaft tubes n and 211 and abut against the curtain edge 131 of the first shaft tube 13 and the side plate 21. And the drive shaft member iq can be provided to generate frictional damping with respect to the swing arm unit 20. 5' is a cross-sectional view taken along line 5-5 of FIG. 3, the paper take-up shaft member 40 is parallel to the drive shaft member 1() and the shaft is disposed at the swing 25 _L ' of the swing arm unit 20. And a second roller 4ι 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, On the other hand, the second gear 42 is axially coupled to the other side of the second roller 41, and the convex tube μ and the shaft hole 44 are disposed in the axial direction. 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.

It is to be noted that the transmission element % may be any mechanism that can transmit the power of the drive shaft member U) to the pickup shaft member 4G, such as a belt. The paper-feeding unit 6A has a linkage shaft member 61 rotatably disposed in the shaft hole 44 of the paper-retracting shaft member 40, and two are respectively fixed at the two ends of the linkage shaft member and located at the swing arm unit. The outer pawl 62 of the 2G and the overload protection elastic element imaginary 1302499 disposed between the paper take-up shaft member 40 and the interlocking shaft member 61 have a positioning sleeve 611 opposite to the convex tube 43, One or two? Each of the positioning end portions (2) fixed to the interlocking shaft member 61 has an oppositely disposed swinging end portion (2) and a second end portion extending to the swinging end portion and facing the paper feed The second direction of the direction X: 623, the overload protection elastic element is a spiral spring, and the opposite two sides are respectively rubbed on the convex tube 43 and the positioning sleeve Mi. 2, FIG. 3, FIG. 5 and FIG. 6, when the 16-axis shaft member 1G is driven to rotate in the middle direction (clockwise direction as shown in FIG. 6), Driving the first roller u and the first gear to rotate 'with the friction member 3 〇 against the edge 311 and the side plate ^ to generate friction damping, the friction damping is converted into a torque, and the The swinging portion 25 of the swing arm unit 20 generates an upward b swing with the pivotal portion 24 as the center of rotation, and the paper take-up shaft member 4G also rotates clockwise with the driving sleeve member iq: and utilizes the overload protection The two end portions of the elastic member 63 and the convex tube 43 and the clamp sleeve 611 are frictionally sheathed, and the rotational power of the paper take-up shaft member 4q is transmitted to the stop unit 6 through the overload protection elastic member 63. The shaft member 61 and the pawl 62 are interlocked, and the pawls 62 can be swung to a paper stop position (see FIG. 6). When the pawls 62 are in the paper stop position, the swing ends of the claws 62 are engaged. The end edge of the portion 622 is abutted on the paper feed tray ιι, and the bottom edge of the second roller 41 of the paper take-up shaft member 40 and the paper feed tray 11 A maximum height H is formed between the turns, and the angle 623 between the stop faces 623 of the pawls 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, and the angle between the stop surface 623 and the paper feed tray 11 is 0, so that the front end of the paper is tilted. 1302499 It is slanted, that is, the paper is slightly pulled apart from the paper, which can effectively reduce the incidence of multiple feeds. As shown in FIG. 3 and FIG. 7 , when the driving shaft member 10 is driven to rotate counterclockwise, the first roller u and the first gear 12 are rotated, and the friction member is utilized. 3〇 abuts against the side edge 21 between the retaining edge 311 and the side plate 21 to generate frictional damping, and the frictional damping is converted into a torsion force, so that the swinging portion 25 of the swing arm unit 2 is pivoted with the shaft

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 up position, when the pawls 62 are in the stowed position, the swinging end portion 622 of the pawl 62 abuts against the drive shaft member 10. Although the drive shaft member 10 is continuously driven to rotate, since the claws 62 have been restrained from being locked on the drive shaft member 1 , the setting of the elastic protection elastic member 63 is utilized, and the torque is overloaded. 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 effects of facilitating paper feeding and automatic paper taking, and when the paper is placed, it is not necessary to forcefully press the paper feeding tray 5 as conventionally, and the leading end of the paper is subjected to the claws 62. The blocking can produce the effect of accurate positioning, and the angle between the blocking surface of the claws 62 and the paper feed tray 110 can make the front end of the paper form an inclined shape, which can effectively reduce the incidence of multiple sheets. 10 1302499 The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change of the patent application scope and the description of the invention is Modifications are still within the scope of the invention.
