Technical Description of the Invention The present invention relates to a paper guiding mechanism of a printing device, and particularly to a paper guiding or positioning by the design of an elastic body and a connecting rod. Organs [Prior Art] Printers, scanners, photocopiers, fax machines, and multifunction printers all include - pallets, a paper guide, and a feeder. The feeder is, for example, an automatic d〇cument. Feeder, ADF). The paper guiding device is slidable on the paper tray to fix the paper on the paper tray to facilitate the automatic paper feeder to feed the paper. As for the structural design of the conventional paper guiding device, a brief drawing will be described below. Please refer to FIG. 1 , which is a perspective view of a conventional printer. In the drawing, the printer 10 includes a paper tray 45 and a paper guiding device 15, and the paper guiding device 15 includes paper guides 20 and 30. The paper guide 30 is fixedly disposed on the paperboard 45. The paper guide 20 is disposed on the paperboard 45 so as to be slidable back and forth along the direction of the arrow 25 of the i-th image, and can be adjacent to or away from the paper guide. When the stack of sheets 4 is placed on the tray 45, one side of the stack 40 must contact the paper guides 3, • and the paper guide 20 will be forced to move in the direction of the arrow 25 of Fig. 1 to Contact the other side of the stack 40. Since there is no anti-slip device between the paper guide 2 and the paperboard 45, the paper guide 2 which has been in contact with the paper stack 40 is very easy to loosen, which makes the paper stack 40 easy to feed one by one by the printer. The phenomenon of paper skewing is affected, which affects the subsequent printing quality. In order to allow the paper guide to be positioned on the paperboard, some operators design a plurality of positioning holes on the paperboard so that the paper guide can be fixed to the positioning holes to define paper of a certain size, such as A5, A4 and B4. Wait. However, the way in which the paper guide plate is fastened to the clamp hole of the paperboard is limited to the TW1364PA 5 1247718. The size of the paper jammed does not allow the user to hold any size paper. In addition, the user must complete the action of the paper guide jamping the paper by inserting and removing the paperboard on the paperboard. Instead, the paperboard can not be freely moved on the paperboard, and the operation is troublesome. SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a paper guiding device. The paper guiding device can be easily slid or positioned on the paperboard by sandwiching the cup to greatly clamp the paper of any size, greatly improving the practicality of the paper guiding device.

The system is slidable on a pallet and the body has an opening. The baffle is disposed on the body. The link has a first end and a second end, the first end being disposed in the opening, and the link being disposed on the board in a manner movable to the first position and the second position. When the link is in the first position, the paper mechanism abuts the paperboard; when the link is in the second position, the paper guide mechanism can slide on the paperboard. <In accordance with still another object of the present invention, there is proposed a lithographic apparatus comprising a pallet Μ and a paper-making mechanism. The paper guiding mechanism is disposed on the paperboard, and the paper guiding mechanism includes a body, a seesaw and a connecting rod. The system can be slid onto the pallet and the body has an opening. The striker plate is disposed on the body. The connecting rod has a first end and a first opening, and the connecting rod is connected to move on the second to the second. Wherein, when the connecting rod is arranged in the position of 帛μ士弟-position, the paper guiding mechanism is abutted against the paper tray; and the paper guiding mechanism is slidable on the paperboard.

The top surface. The fixed cantilever 64 is spaced from the upright side 63 by a distance, and the second end 72b of the link 72 is movable between the upright side 63 and the fixed cantilever 64. The fixed cantilever 64 is used to limit the range of swing of the link 72 such that the link 72 is movable between the first position and the second position. Further, the manner in which the fixed cantilever is disposed is not limited thereto, and the fixed cantilever may be connected to the first protrusion 65 to be integrally formed. With such a design, a track is formed on the baffle for the second end 72b of the link 72 to move on the way. The paper guide mechanism 100 further includes a second protrusion 66 and an elastic body 67. Elastomers | 67 are for example springs or springs. The second protrusion 66 is disposed on the upright side surface 66 and spaced apart from the first protrusion 65, and the second protrusion 66 and the first protrusion 65 are located outside the two sides of the link 72, respectively. The two ends of the elastic body 67 are respectively connected to the second protrusion 66 and the link 72, and the elastic body 67 provides an elastic force to push the link 72 as the predetermined internal force. Fig. 4 is a cross-sectional view showing the printing device of Fig. 2 taken along the yz plane of the opening of the paperboard and viewed in the -X direction with the link in the first position. Referring to FIG. 4, when the link 72 is in the first position, the flipping plate 73 disposed at the first end 72a of the link 72 abuts the carrier 50, whereby the paper guiding mechanism 1 abuts. The paperboard 50 is positioned on the paperboard 50. At the same time, the elastic body 67 is in the first state to provide a force, and the connecting rod 72 is pushed by the force of the elastic body 67 so that the connecting rod 72 abuts against the first protrusion 65 and is located on the bottom surface of the flipping plate 73. The friction plate 74 is in close contact with the paperboard 50. The elastomer, 67 is a compression spring, and the first state of the elastomer 67 is preferably in a compressed state. It should be noted that the friction between the friction plate 74 and the paperboard 50 is sufficient for the paper guiding mechanism 100 to be positioned at any position of the paperboard 50 to achieve the anti-slip effect of the paper guiding mechanism 100. When the urging arm 71 is applied with a reverse external force TW1364PA 8 1247718 - which is greater than the force of the elastic body 67, the link 72 is swung to the second position in the direction of the arrow 101 of Fig. 4. Figure 5 is a plan view of the ζ-γ section of the paper guiding device which is not observed in the direction of the link in the second position. The link 72 will be remote from the first projection 65 and adjacent to the second projection 66. The elastomer 67 is further compressed while the friction linings are substantially detached from the pallet 50. At this point, the paper guide mechanism can be slid back and forth along the yoke direction on the pallet 50a. When the paper guiding mechanism i 〇〇 moves to a preset position, once the reverse external force originally applied to the urging arm 71 is removed, the link 72 returns to the first position as shown in FIG. 4, and the elastic body 67 is The second embodiment of the present invention is shown in FIG. In Fig. 6, the paper guiding mechanism 100a of the present embodiment differs from the paper guiding mechanism 1 of the first embodiment in the design of the elastic body and the second protrusion, and the labels of the other identical members continue to be used. In FIG. 6, the second protrusions 66a are disposed on the upright side 63, and the first protrusions 65 and the second protrusions 66a are located on the same side of the link 72, and The two protrusions 66a are farther from the link 72 than the first protrusions 65. The second body of the elastic body 67a The ends are respectively connected to the second protrusions 66a and the connecting rods 72.
