[Embodiment] In order to explain the technical contents, structural features, objects and effects of the present invention in detail, the embodiments are described below in detail with reference to the drawings. Referring to the third figure, the paper taking mechanism i having the paper stopper device includes the upper cover 10, the paper picking 2G, the paper separation roller 3, the roller frame 4G, the bottom wall 5G, and the paper feeding device 60, "mouth" ; read the fourth figure '1G inside the convex cover __ on the parallel holding plate 11 holding part, a retaining hole U1 is formed on the holding part u, and the retaining part ^ is provided with a plate-like limiting part 12. A pair of flat pivoting portions 13 are protruded from the upper cover 10 below the holding portion u, and a receiving space is formed between the two pivoting portions 13! 4. Referring to the fifth figure, the roller frame 4 has a side wall, and the side wall includes a left side wall 41 and a right side wall 42. The left side soil 41 and the right side wall 42 are correspondingly provided with two parallel rotating shafts and a short rotating shaft. A paper separation roller 3 is fixed on the rotating shaft 43, and a paper take-up roller is fixed on the short rotating shaft 44. := 7 % Μ The paper take-up roller and the knife and the roller 30 are pressed against the roller frame 4 inward. Referring to the second and sixth figures, the pickup device 60 includes a paper stopper 61 and an abutting block 62. Block · μ曰▲ " W 61 ^ The Ministry of Finance expands outward = there is a connecting portion 6丨丨, the opposite sides of the connecting portion 611 are large ^ into two clamping axes 612. The front end of the connecting portion 611 extends upwardly by the M3180ii limiting arm 613, and the limiting arm 6i3 can block the limiting portion 12 of the upper cover 1Q. The rear end of the connection 4 611 extends downward to form a sowing arm 614. The paper stopping arm 614 forms a resisting portion 615 near the upper end of the left side wall 41-side, and a bottom notch 616 is formed through the bottom end of the paper carrying arm 614. The abutting block 62 is convexly or fixedly attached to the left side wall 41 of the roller frame (9) and has a cylindrical shape. Referring to the third to sixth figures, the belt 21 is simultaneously sleeved on the take-up roller 20 of the short-rotating shaft 44 and the paper-distributing roller 3 fixed on the long-axis 43 and then rotated _ #43 And the short miscellaneous 44 _ bribe is disposed in the left frame 41 and the right side wall 42 of the roller frame, and then the roller frame 4 〇 is received in the accommodating space 14 of the upper cover 1 ,, and the long rotating shaft 43 is pivotally connected to the upper cover 10 In the planting part 13. The paper feeding device 6 is disposed on the side of the roller frame 40 and adjacent to the left side wall 41. The two positioning shafts 612 are respectively connected to the two lids ill of the upper cover 1 , and the pick-up member 61 can be rotated and abutted around the positioning shaft 612 . The block 62 abuts against the upper end of the paper stopper arm 614 of the paper support member 61. Finally, the assembly of the paper take-up machine (1) having the paper stopper device can be completed by attaching the upper cover to the bottom wall 50. Lu 4 refers to the seventh figure. When the paper pick-up mechanism 1 does not take paper, the pick-up paper roller 2 is located above the paper and is spaced, and the distance of the paper is 2 - the distance of the paper 2 is blocked by the paper-piercing arm 614. The paper mechanism 1 is 'at this time', the paper stopper 61 is in a natural vertical state, and the abutment 4 615 of the paper stopper arm 614 is abutted by the abutment block 62 and cannot rotate clockwise, and the limit arm is in abutment by the limiting portion 12 and cannot Anticlockwise rotation. Continued, please refer to the first and ninth figures. When taking the _ _ 1 side _ paper signal, the motor (not shown) _ long shaft 43 _ needle _, the paper separation roller 3 on the shaft 43 is also followed When the hour hand rotates, the friction roller between the paper separation roller 3〇 and the belt ^ generates M318011, which causes the belt 21 to rotate clockwise, and the friction between the belt 2i and the pickup roller 20 drives the pickup roller 2 to rotate clockwise. . Since the take-up roller 20 and the separation roller 30 both press the roller frame 4 inwardly, frictional force is generated between the two rollers and the roller frame 40, so that the roller frame 4 is rotated downward around the long shaft 43 and The pickup roller 20 presses the paper 2 . At the same time, since the roller frame 4 turns downward, the abutting block 62 provided on the left side wall 41 also moves downward and passes through the notch 616 of the blocking member 61 (refer to the sixth figure) and is located at the paper stopping arm. Before 614, there is no longer any resistance between the abutment block 62 and the abutment portion 615 of the sowing arm 614. At this time, since the skin b is pressed against the paper 2 and rotated clockwise, the friction generated between the belt 21 and the paper 2 takes the paper 2 into the pickup mechanism 1, and the paper stopper arm 614 is wound under the pushing of the paper 2. When the positioning shaft 612 is rotated backward to the bottom end of the paper stopper arm 614 on the paper 2, the paper 2 can pass through the separation roller 3 () without entering the paper take-up mechanism ι. On the contrary, when the paper picking mechanism 1 stops picking up the paper, the motor instantaneously reverses and drives the long rotating shaft 43 to rotate counterclockwise instantaneously. Then the paper separating roller 3 rotates counterclockwise and drives the belt 21 to rotate counterclockwise, and the belt 21 is again The paper take-up roller 20 is rotated counterclockwise. Since both the Changna 43 and the short rotating shaft 44 press the roller frame 40 inward, the separation roller 30 and the roller 2G are reversely transferred to each other. With 2 ^ 4 43 43 object to the field, paralysis 20 and paper TO above the paper 2 - the distance, the paper stopper arm (10) in front of the action of its own gravity, @ 612 (four) needle rotation, in the process of abut the block 62 from the paper stopper arm 614 Γ 616 (please refer to the sixth figure) and located behind the paper urging arm 614, the 擒 615 615 'limit (10) blocking the upper cover, M318011, read the eighth figure ' At this time, the paper stopper 61 is In the natural vertical state, the paper 2 is blocked by the paper stopper arm 614 outside the pickup mechanism 1. As described above, the paper take-up mechanism 1 having the paper stopper device of the present invention uses the resisting fit of the paper stopper 61 and the abutting block 62 to achieve the paper blocking effect, and the abutting block 62 can be taken from the pick-up member 61 when the paper is taken. When the notch 616 passes through, the paper stopper 61 and the abutting block 62 do not need to be press-fitted, so that the paper stopper 61 and the abutting block 62 can be easily engaged, so that the paper taking is smooth, and the entire paper taking mechanism 1 can work normally.
