200530050__ V. Description of the invention ⑹ B ----- Figure 4 shows the __thinking diagram of the invention with a paper separation and reversing device. The printer 100 includes a casing 30, a paper separation and reversing device 10, and a driving device (not shown), wherein the paper separation and reversing device 10 and the driving system are respectively disposed in the casing 30. The paper separation and reversing device i 〇 is used for the conveying direction of objects such as sheets. It should be noted that the present invention mainly proposes improvements for the paper separation and reversing device 10 of the printer, and for convenience and clarity of explanation, it is wider than other devices of the printer that are omitted from the drawing. FIG. 5A shows a schematic diagram of the combination of the paper separating and reversing device 10 of the printer of the present invention, and FIG. 5B shows the paper separating and reversing device 10 of the printer of the present invention: disassembly is not intended. As can be seen from Figures 5A and 5B, the paper separation and reversing device 10 includes a frame Φ 25, an ejection mechanism 11 and first and second paper separation elements (f ⑽ 廿 second duplex uni t) 1 3, 14 〇 The first and one paper separating elements 1 3 and 1 4 include first and second switching arms 15 and 16 respectively. The frame 25 includes at least two holes 251 and 252. The holes 251 and 252 respectively correspond to the first and second switching arms 15 and 16. When combined, the first and second switching arms 5 and 6 are rotatable. The method is arranged in the holes 251 and 252, so that the first and second paper separating elements 13 and 14 are fixed on the frame 25. The ejection mechanism n is composed of a push rod 21 and a convex wheel 22, and is located on the same side as the first and second switching arms 15, 16 on the frame 25. In addition, it can be seen in the combination diagram of FIG. 5A that 5 on the first switching arm abuts on the top 2 1 4 of the push rod 21. The putter 21 includes a slot 2 11 and at least

〇535-A20360TWF (Nl); F〇3095; YUCHIA.ptd Page 10 2005200550 V. Description of the invention (7) A chute 212, wherein the slot 211 is used for inserting the second part of the second tiller element 14 Switching arm 16. The first and second paper separating elements 13, 14 are configured by the first and second switching arms 15, 16 and the ejection mechanism n and are movably arranged on the frame 25 to form an inlet 12 and an outlet 17, 18, 19 of the three choices. As mentioned above, the paper enters the separation and reversing device from the entrance 丨 2, and the printed paper can be output to one of the exits 17, 18, and 19-the output direction, as shown in Figures 6A-1 to 6C-2. As shown. The cam 22 is connected to the bottom 215 of the push rod 21, and the connecting portion 221 of the cam 22 is connected to a driver (not shown). The driver drives the cam 22 to rotate, so that the push rod 21 stays at three different height positions. (As shown in Figures 6A-1 and 6A-2 and 6B-2) and the first one), the second position is the first and third positions (the first separation element is the reference position (the 6A -1, 6A-2 Figure wheel 22 and putter 21 are not necessarily the starting position at the lowest position, so they are not limited to three positions. The upper part, and the first, therefore, the putter 21 can be shown in a first position), a second position (as shown in FIG. 6B), a three position (as shown in FIGS. 6C-1 and 6C-2 (see FIG. 6B -1, 6B-2) The height is between 6C-1, 6C-2), and if the first position is compared to the second and third positions, the first) is the lowest, which is the first The position is when it is convex. It should be noted that the first position can be transformed from the second position to the first position. As shown in Figures 6A-1 and 6A-2, at the time 'in this example In the first position, the second protruding part 16 of the preset position 1 6 1 is located in the slot 2 11

200530050

The protruding portion 151 abuts on the top 2 14 of the pusher 21, so that the first paper separating elements 13, 14 are located at the first and second sinking positions, respectively: when ^ is above the first paper separating element 丨 3 As the surface passes, the forward direction of the paper is shown by two-way arrows. As shown in Figures 6B-1 and 6B-2, when the cam 22 rotates, the pusher moves up to the second position. 'Push rod 2 1 pushes the first switching arm. The first protruding portion 151 is rotated, and the first switching arm 15 is connected to the first paper separation 7G piece 1 3, so that the first paper separation element i 3 is located in the first upward position and the second switching arm 16 is protruded secondly. The portion 161 is located in the middle of the slot 2i i. At this time, the second paper separating element 14 is also located in the second upward position, and the first paper separating element 13 is attached to each other. The paper separating element 14 passes below, and the advance path of the paper is shown by an arrow in the B direction. When the cam 22 continues to rotate and the push rod 21 continues to move upward to the third position, the second protruding portion 161 of the first switching arm 16 is located at the lowermost part of the slot 211, so that the first separating element 13 is tilted upward and the second separating sheet The element 14 sinks, and the paper passes between the first paper separating element 13 and the second paper separating element 14. The paper advance path is shown by the arrow in the C direction.

^ Furthermore, the housing 30 of the present invention has an extension portion 31, and the extension portion 31 extends toward the inside of the housing 30, and is on the push rod? !! With slide = 212 and a positioning element 40 (for example, a screw), the positioning element 40 passes through the chute 2 1 2 to connect the push rod 21 and the extension 3 1 so that the push cup 2 1 It can only move in the direction in which the chute 2 1 2 extends. In other words, this design allows the push rod 21 to move only in a direction perpendicular to the axis of the switching arms 5 and 6

200530050 Five 'Explanation (9) to prevent the putter 21 from shifting. In summary, the driving device in the printer is used to drive the projection and the push rod 21 connected to the cam 22 pushes the upper and lower separation sheets through the two switching arms 15 and ^ 丄 151 and 161. The components 13, 14 are respectively turned by 2 large fixed angles, and stay at the corresponding positions, tilt up or sink, and switch between the current / knife reversing components between the three paper output directions. As can be seen from the above description, the present invention provides a paper separation and reversing method. With one page-out mechanism, it can realize the advancement in three directions, only two of which achieve the same purpose as the conventional technology of paper separation. In the present invention, the direction of the printer's paper after the setting is as follows: The knife paper has low manufacturing cost. It is easier and easier to install from 讦, and the installation is also related to the size of the slot and the distance between the push rod 2 丨. Therefore, the size, the angle and length of the switching arm, and the size of the cam. Although the slot is not limited, although the present invention has been described with several preferred implementations to limit the present invention, anyone skilled in the art can still do two things within the spirit and scope of ', but it is not Departure from the protection scope of the present invention shall be subject to the appended claims, retouching, and retouching. Therefore, the scope of the patent scope of the present invention shall prevail. Page 13 〇535-A20360TlVF (Nl); F03095; YUCHIA.
