Description of the Invention: [Technical Field] The present invention relates to a paper-stopping structure, and more particularly to a movable paper-feeding structure for sorting the leading edge of a paper in a cattle feeding mechanism. [Prior Art], the automatic paper feeding function is a basic configuration function of the multi-machine, such as a fax machine, a photocopying machine, or a scanner, etc., having an automatic document feeding mechanism (ADF) Inside, used to feed the paper in the "hidden" into the machine body. When the fed paper is transferred between two predetermined positions, it is transferred from the paper storage slot to the inside of the transaction machine for the next - When the step is processed, the automatic document feeding mechanism usually uses the paper baffle _ to complete the positioning and the action of the paper. See the figure - shown in the figure, which is the mechanical type disclosed in US Patent No. 6, 557 '848 Β 2 The paper cassette structure is used to control the paper into an automatic paper feeding mechanism, and includes a shaft 35a, a motor that rotates the shaft 35a (not shown), a cam structure 32a, and a paper stopper. The arm 3la, and an elastic engagement state 33a. The cam structure 32a includes a first protrusion 321a and a second protrusion 322a, and the cam structure 32a is rotated by the shaft 35a to rotate the first protrusion 321a and the second protrusion 322a; The force point 3· (as shown in the figure), the force point 3 moves the paper stopper arm 31a upward according to the rotation of the first protrusion 321a; the elastic clutch 33a is the paper stopper arm 31a. When the upward movement is performed, the paper stopper arm 31& is engaged with the card 2 in the paper feeding position, and the elastic engagement device 33a is displaced according to the top of the rotation of the second projection 'a, thereby causing the paper stopper arm 3la to be disengaged from the elastic force to be stuck in 1291446. And move down and be in the - blocking position. However, as mentioned above, the above components: the complexity of the components is not only the cost of making components, but also: taking into account the two-to-two hybrid _ combination tolerances, and each component has its own assembly Different, you need to first locate each other to confirm the combination [can not be completed in the same step - in the step; in addition, due to the increase in the combination of variables, the looseness of the --piece will cause structural failure, increase the trouble and long South Maintenance costs. Ming 爹 第 Α Α Α Β Β Β 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾 台湾The shaft IV is rotated to extend over the socket W1, and a torque limiting device 152b is disposed on the other end of the shaft 15Gb; the torque limiting device 152b includes first and second plates 152P1, 152P2 and An elastic member 152S, wherein the elastic member 152S is in contact with the shaft 15〇b by the second plate 152P2, and is pressed against the gear i5〇G by the first plate 152P1. The support plate i5b_2 is an approximately L-shaped plate, and one of the cams 151 is pressed against the baffle 15b-2, and the plurality of papers p can be aligned and positioned by the side of the baffle 15b-2. . The baffle 15b-2 is partially accommodated in the two guiding slots l8b of the base h-2, and the baffle 15b-2 is accommodated by the positioning holes 1〇8H of the two guiding slots to receive the baffle 15b-2 The lower end can be extended into the positioning hole 108JJ, so that the baffle 15b-2 can align and position the plurality of sheets P. As described in the second prior art, since the paper retaining device 15b is provided with the cam 15b-1 and the baffle 15b-2 on both sides, the second conventional baffle 15b-2 is integrally formed by the span 1291446. The way of presenting the paper from top to bottom is still limited; however, the device still has its limitations in practical applications, and the integrally formed baffle 15b-2 is easily deformed to cause a warped state, and the one side is inclined to cause the two sides to be equal and lose The function of the two baffles 15b-2 at the same time is to complete the paper; in addition, a plurality of gear devices 10' need to be disposed between the two baffles 15b-2, in fact, the two broadcast plates Mb-〗 are not symmetrically arranged, and the swing arms are more A long baffle l5b-2 is more likely to be loosened due to the leverage effect, which consumes maintenance costs. The reason is that the inventors have felt the above-mentioned deficiency, and have devoted themselves to research and cooperation with the use of academics and the convenience of carrying characteristics, and finally proposed a present invention which is rational in design and effective in improving the above-mentioned defects. SUMMARY OF THE INVENTION The main object of the present invention is to provide a movable paper support structure which is applied to an automatic document feeding mechanism and which has the function of conveying paper and finishing the leading edge of the paper to avoid paper jam. The second-purpose of the present invention is to provide a movable paper name for the automatic document feeding mechanism, which is linked to the transaction machine; no additional production or power supply is required to increase the cost of the structure. It is possible to provide a kind of movable paper-loading mechanism in the automatic document feeding mechanism, which is achieved by using a simple mechanism to achieve less r-type and achievable domain, and to reduce the assembly structure, ί:: self-moving: Yes, for a movable type of crepe paper knot, money structure, #, can avoid deformation and produce two ends 1291446 10 and fail; the connecting rod 3 and the draft roller rod 2 are provided to enable the connecting rod 3 to be rowed (four) the wheel rod 2, j The fixed friction time connecting rod 3 and the drafting roller rod 2 can be relatively rotated: the connecting rod 3 is restricted by the wheel rod 2 as the main:: All components of the moving paper blocking structure are rolled by the magazine == machine Not only can the first-in-one component of the first-known component be avoided, but the t-time line is lost, and the number of the connecting rods 3 of the movable paper-feeding structure can be avoided: the two are not integrally formed. Ways to complete the production, can avoid the problem of the two sides are not equal, and the related results caused by the shell effect Off phenomenon. The mobile paper-blocking structure of the Department can avoid the human factors such as different operating habits when the paper is pre-loaded ==, so that each time the paper: resident, ", the position is not the same, the paper may be made If it is slipped over, I, money, or unable to separate paper, it will be invalid. * It will only avoid the inconvenience to the user. This will reduce the maintenance burden caused by the above situation. Point: From the previous knowledge, the hybrid structure of the present invention It has the following advantages: 1. It is true that the financial outlook and the finishing of the paper front edge are free of secrets; 2) The use of the motor for the internal paper feed of the machine, the helmet must be additionally produced or matched with the moving reading to improve the cost; ^ 3. With a simple mechanism to achieve, reduce costs, assembly steps are reduced and modular applications, to reduce the labor time spent on assembly; and 4. Can avoid deformation and warping caused by loosening. 12 1291446 Limitation (4) μ material The recording of the present invention is feasible, and therefore it is not the case within the six. Therefore, the use of the specification of the present invention and the transformation of the internal structure of the invention are included in the scope of the invention.
