Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a paper feeding device, and more particularly to a paper feeding device having a paper stopper. [Prior Art] Traditionally, when a user wants to scan a large amount of paper, it must be placed in the scanner to be scanned in a page-by-page manner, thereby wasting a lot of valuable time and human resources. In view of the fact that most of the current scanners are equipped with a paper feeding device, the user only needs to place the paper on the paper feeding path of the paper feeding device, and the paper feeding device drives a dragging device above the paper feeding channel. The paper take-up module feeds the stacked sheets into the broom, thus automatically completing a stack of dozens of pages of paper scanning. In order to ensure that the user can correctly place the paper on the paper feed path, the conventional paper feeding device is provided with a _ paper stopper under the paper take-up module for pushing the paper into the user. When feeding the paper path, the paper is positioned at the leading edge of the paper to position the paper below the paper take-up module, and the user feels that the paper has been placed. When the paper feeding device drives the paper take-up module to perform the paper picking operation, the paper stopper is removed to allow the paper to smoothly enter the inside of the paper feed path. 5 1290098 The first figure shows a perspective view of a paper take-up module and — which are conventionally arranged in the paper feeding device. The paper stopper 12 is rotatably disposed under the paper take-up module u. The paper take-up module u includes a dust-receiving portion (1), and the paper-stopper 12 includes a tilting portion (2) and a paper stopper portion 122. . When the paper take-up module u_to_prepared, the paper-stopping portion 122 of the member 12 is in a standing state, so that the paper can be pushed against the leading edge of the paper. When the paper taking operation is lowered to the paper take-up position and the paper picking operation is performed, the pressing portion (1) of the paper take-up module 11 is also lowered to press the inclined portion 12 of the paper picking member, thereby causing the paper carrying portion 122. The rotation is generated and lowered to the lower side of the paper feed passage, after which the paper is freely passed through the top end of the inclined portion 121 without being blocked. The paper stopper 12 of the above conventional paper feeding device has the following problem, that is, when the user puts the f paper into the paper feed passage, since the paper stopper portion 122 of the paper stopper 12 can only abut against the bottom paper, Therefore, the paper on the top layer is directly contacted and pressed down to the inclined portion 121 of the paper stopper 12, so that the paper stopper 122 has been lowered to the lower side of the paper feed passage and the paper is lost when the paper picking operation has not been performed. . SUMMARY OF THE INVENTION An object of the present invention is to provide a paper feeding device and to provide a paper stopper that can be engaged with a paper take-up arm to appropriately prevent paper from entering the inside of the paper feed passage or allowing paper to enter the inside of the paper feed passage. 6 1290098 The present invention provides a paper feeding device, comprising: a casing, the casing includes a paper feeding passage for carrying paper; and a paper removing arm pivotally disposed above the paper feeding passage and movable to a a first position or a second position and the pick-up arm comprises a bump; and a paper stop, the paper stop is located below the paper feed passage, the paper stop comprises a pivoting portion and a paper stop, and the paper stop The portion includes a hook; # wherein, when the pick-up arm is moved to the first position, the bump is located on the swing path of the hook to restrict the swing of the paper-making portion, and when the pick-up arm is moved to the second position At this time, the bump is moved to the lower side of the hook to allow the paper stop to swing freely. Preferably, the paper stopper further includes a load portion, the load portion and the paper collision portion are respectively disposed at both ends of the drag portion, and the moment at which the load portion is applied to the pivot portion is greater than the moment at which the paper stopper portion applies the pivot portion. 10 1 The father of the paper, the paper feeding device further includes a torsion spring disposed on the paper feeding portion. [Embodiment] The second figure is the invention. The preferred embodiment of the paper feeding device 2 includes a casing 20, a paper take-up module 21, and a paper-stopper, and a channel 2,1 The group 21 carrying the user's desired broom is pivoted above the mineral paper channel 2〇1 for performing an appearance view of the paper take-up. Feed paper loading 22. The paper S of the casing 20 is wrapped. The paper take-up mold feeds the paper S into the inside of the paper feeding unit. The paper take-up module 21 includes a pick-up arm 211 and a drive member 212', wherein the pick-up arm 211 includes a pick-up roller 211A and a separation roller 211B (t^ reference to the third A-picture), and the drive shaft 212 passes through the pickup arm 211 and is sleeved on the separation roller 2 . When the paper feeding device 2 has not been subjected to the picking operation or the paper feeding device 2 has completed the paper taking operation, the pickup arm 211 is driven by the driving shaft 212 to be lifted to a pre-injury pickup position, and when the paper feeding is performed When the apparatus 2 performs a paper picking operation > the paper picking arm 211 is driven by the horse moving shaft 212 to be lowered to a paper take-up position, and the paper take-up roller 2iia directly contacts the top surface of the paper S to perform a paper picking operation. According to the second figure, the paper raising member 22 is pivotally disposed under the paper feeding passage 2〇1 and has an opening groove 202 (refer to the fourth a coffee, the paper take-up arm of the Langer pickup module 21) When the 211 is raised to the preliminary paper take-up position, the paper-producing member 22 is kept in a standing state to prevent the paper s from entering the inside of the paper feed passage 201, and when the paper take-up arm 211 of the paper take-up module 21 is lowered to the pickup position When the paper-producing member 22 is free to swing to allow the paper s to pass through the paper stopper 22 and enter the inside of the paper feed passage 2〇1. The second A_ and the third b_ display the paper take-up module 21 and the viewing member r A perspective view, thereby explaining how the paper-producing member 22 is kept in a standing state when the paper-removing arm 211 of the paper take-up module 21 is raised to the preparatory position, and when the paper-removing arm 211 of the paper-removing module 2 is lowered When the aging is set, how the viewing member 22 recovers from the __.
