Field of the Invention The present invention relates to a paper feeding mechanism and an automatic paper feeding device using the same, and more particularly to a paper feeding mechanism having a blocking member and an automatic paper feeding device using the same. - [Prior Art] The supply tray of the conventional automatic paper feeding device can be designed to be inclined or horizontal. The slanted supply paper cassette can use gravity to achieve the paper feeding action, but takes up a considerable amount of space and does not meet the requirements of miniaturization. A horizontal or nearly horizontal supply of paper does not take up a significant amount of space, so it can meet the requirements of m', but it needs to be fed in with the paper feed mechanism. At present, the automatic paper feeding device on the market uses a pick-up roller that can be rotated up and down, and can be taken up. In order to effectively prevent multiple sheets from being fed into the paper feed path, a paper stopper mechanism is required to limit the position of the paper on the paper to prevent the paper from directly entering the paper feed path. This paper stopper mechanism needs to cooperate with the action of the pickup roller to perform the paper-blocking function of the field. The conventional paper stopper mechanism includes a rotary paper stopper mechanism, a telescopic paper stopper mechanism, and the like. The secrets of these paper-piercing mechanisms/70 pieces of raw β-paper are located on both sides of the pickup roller. The two paper-stopping elements also need to be interlocked, thus causing a large number of parts = a complicated connection method. The installation and disassembly of the pickup roller is complicated, which is not conducive to the repair and replacement of the pickup roller (4). Therefore, providing a paper feeding mechanism having a simple structure and an automatic paper feeding device using the same is the solution desired by the present invention. SUMMARY OF THE INVENTION Accordingly, the present invention provides a simple paper feeding mechanism and an automatic paper feeding device using the same. To achieve the above object, the present invention provides a paper feeding mechanism comprising a first body, a second body and a blocking member. A first-roller is mounted on the first body. The second body is pivotally connected to the first second roller. Blocking element (4) is connected to the first - the first: the body is directly driven. When the second body is rotated in a shape relative to the first body, the blocking member is rotated in a closed state with respect to the first body to prevent the paper from moving to a paper feeding position in contact with the first roller. When the body rotates into the m state relative to the first body, the blocking member 70 is rotated into the open state relative to the first body to allow the paper to move to the paper feeding position in contact with the first roller. The invention also provides an automatic A paper feeding device comprising a supply paper, a channel, a paper feeding mechanism and a paper feeding mechanism.

[Embodiment] The sound reproduction device is not based on the automatic paper feeding device of the preferred embodiment of the present invention: 2 to 4 are views showing two operational states of the paper feeding mechanism in accordance with the first embodiment of the present invention. - for: "As shown in Fig. 1, the automatic paper feeding device of the embodiment comprises a paper machine: 4 Γ 10, a paper feeding path 20, a paper feeding mechanism 3, etc. Further, the automatic paper feeding device may further comprise a Friction 蛰 Therefore, the automatic money device can be a file scanning device 'so it further includes a scanning module 60. The supply paper Π is horizontal or nearly horizontal for storing a medium sheet of paper 1 paper The channel 2 is formed in the automatic paper feed ... and is connected to the supply paper cassette 1 '. The paper feed mechanism 40 is used to feed the paper sheet s entering the paper feed path 2 to the paper feed passage 20. In this embodiment In the example, the paper feeding mechanism 4 is opposite to the rollers 41 and 42 and the other pair of rollers 43 and 44. The paper feeding mechanism 30 includes a first body 31.

The mouthpiece is again when the second body 33 is rotated with respect to the first body 31 into a single heart H piece 35 With respect to 帛f: the paper S is moved to the paper feed path 2. The entrance 21 is closed: 疋 The paper S is prevented from moving to the paper feed position PI of the first 'm wheel 32 as shown in Fig. 2, 35, the paper must be blocked The person 34 is lifted, and the blocking element is 'blocking element #35 relative to the first body η :: state when the second body 33 is opposite to the first body _ state to allow The population 9 1363736 moved to the paper feed path 2Q is to allow the paper S to move to the paper feed position pi in contact with the first roller 32, as shown in Fig. 4. That is, the blocking element when the second roller 34 is dropped; The blocking member 35 can be inserted into the guiding groove 331. Thus, as shown in FIGS. 2 to 4, the second body has a guiding groove 33 1 'one end of the blocking member 35 is inserted into the guiding groove 331, so that the blocking element 35 can be As the second body 33 rotates, the guide groove 331 is formed as a groove on the second body 33.
