The spring bearing member 51 is driven by the urging member 18 of the rotary spring 53, and supports The component 3 is a component that pushes the original scraping plate 12 in the opening direction when the pusher __ 丨 付 锊 锊 锊 3 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 4 压缩 压缩 压缩 压缩 压缩 压缩 压缩 压缩 压缩 压缩The upper plate 41 of the lifting element 4 is in contact with or close to the upper plate 31 of the member 3. At this time, the upper plate 41 is preferably, for example, slightly parallel to the contact glass 13. The bottom of the cam slider 52 (sometimes called The outer surface of the occlusion portion is provided with the inclined cam portion 56 and is pressed against the pressure receiving means 16. If the original hinge plate 12 (refer to FIG. 3) at the closed position is pivoted away from the contact glass π by the first rotating shaft 15 When the direction (upper) is rotated, the place where the pressure receiving means 16 is touched will be from the projection 56a to the inclined portion 56b. The sliding member 52 is slowly slid and moved, and the cam slider 52 is slid by pressing the compression screw magazine 53 in the branch member 3 toward the rear end portion, and the compression coil spring 53 is slowly elongated. The coupling mechanism 6 is disposed on the support member 3. On both sides, the first link 20 201138597 body 7 first-link arm 8, the middle first link arm 7 is a ^^^9 and a cam means H), the two ends of the shaft 15 and the flute f The rotatable shaft is supported by the movable portion of the first portion that is rotatably supported by the second brother, and each of the ends is paired, and the two connecting means 9 of the pair of first cores are connected to each of the movable ends. The cam hand and the first cam member of the second pair of arms that are the same pair. It is a pair and is composed of two cam elements; 4 provided by the connecting means 9. The first connecting arms 7 and _ provided on both side portions of the cam slider 52 are configured by the pair of the first wheel means 10, and are either (four)/connected. . The hand 1 and 9 and the pair of convex component symbols 7b are the f of the surnamed hand corpse 9, and only one can be used. Again, -,, D. 连结 〇 9 is a connecting hole, the symbol 8a is a washer, and C:: 8C is a connecting hole of the actuating element 18 and the connecting means 9. The material 9 is connected to the deforming shaft portion 14a of each of the connecting rods of the second connecting arm 8 and the second connecting arm 8 is inserted into the joint (four) - the deformed (four) hole &f; and simultaneously deformed and extracted. The deformation assembling hole 19a of the first cam member 19 is fixed by the fixing pin 19b. The following description will explain the effect of the original plywood opening device of the present invention and the transaction machine to which the original plywood opening device is applied. As shown in FIG. 3, FIG. 6, and FIG. 9, when the closed document overlapping plate 12 is pressed against the contact glass 13 of the scanning portion of the machine body 11a, the original dusting plate 12 is heavy (four) and the spiral is generated. Turning the thin manuscript (not shown) to the contact glass according to the force of the dynamic force. Also, here, it can be formed on the original plate ί2 plus its own weight and 21 201138597 The opening device ^ turns to a dynamic potential in the direction of pressing. In this closed sorrow, the elastic means 5 is in the largest contraction state. Further, the first cam member 19 and the member 54 of the cam means 1 () of the link mechanism 6 are in contact with each other. Then, in order to open the original pressing plate 12 and hold the handle portion 12a provided on the current side thereof in the opening direction, the original pressing plate η and the lifting member 4 and the supporting member 3 are simultaneously opened by the original pressing plate. The recognized first shaft 15 is opened for pivotal rotation. However, at this time, although the supporting member 3 is rotated in the opening direction with the first rotating shaft 15 as a fulcrum, the first connecting arm 7 and the second connecting arm 8 of the connecting mechanism 6 press the first cam member 19 against the cam slider. The second cam element 52 is provided, whereby the lifting element A is pulled in the opposite direction to the rotation direction of the supporting member 3 through the first connecting arm 7 and the second connecting arm 8, so that the lifting element 4 is A rotating shaft #17 is rotated as a pivot point in the opposite direction of the rotation direction of the bearing member 3. As shown in Fig. 7, Fig. 11, and Fig. 11, the original dusting board 12 assembled to the lifting member 4 is kept at a level relative to the contact glass. The state is opened in the vertical direction. As shown in FIG. 7 and FIG. u, the original plate 12 is opened in a vertical state in this horizontal state, and the rotation angle of the support member 3 is 3 degrees. When the angle is exceeded, the cam of the link mechanism 6 is used. The means 1 means that the direction of rotation of the lifting element 4 is opposite to that of the previous one and becomes coincident with the reading element 3. Therefore, as shown in FIGS. 8 and 13, the platen U is opened at 6 degrees, and then the lifting element 4 and the support are supported. Component 3 coincides with this state turned on. Therefore, In the fully open state shown in Fig. i, the rear portion of the original panel 12 does not have to protrude toward the rear of the machine body lu. This feature is different from the invention of the patent document 2011. The next step is to close the opened original document panel 12, As shown in Figs. 8 and 13, the closing angle of the lifting element 4 is such that the original pressing member 12 overlaps with the binding member 3, and is simultaneously rotated and closed with the supporting member 3. Then, if the closing member is closed, the closing member is closed. When the angle is 6 degrees, the second cam member 54 of the coupling mechanism 6 provided on one side of the cam slider 52 pushes the first cam member 19 downward, and thus, as shown in FIG. 7, FIG. 1 and FIG. The original pressing plate 12 reverses the elevating member* through the first connecting arm 7 and the second connecting arm 8, whereby the contact glass 13 is closed in the vertical direction while maintaining the horizontal state. Therefore, the original pressing plate 12 is in contact with the glass 13 The horizontal state is closed, and therefore, the deviation from the thin original on the contact glass 13 can be effectively prevented by the wind pressure. Further, 'as opposed to a book-like thick original as shown in FIG. 7 and FIG. Keeping a horizontal state and being closed, therefore, compared to the conventional technique The apparatus does not need to reverse the elastic force of the elastic means 5 to horizontally cover the upper surface of the original pressing plate 12, so that the original pressing plate is reversed, so that it is unnecessary to apply unnecessary force to the contact glass 13 and the thick original D. Fig. 14 is a view showing another embodiment of the opening mechanism of the original plywood. According to the drawing, the revolving coil spring 1 of the original plywood opening device (1) of the second embodiment is provided with a conventional structure. Damping device (dam (4) (8). When the document pressing plate 12 is rotated in the closing direction, the damper device 101 is only at a specific rotation angle below the arbitrary rotation angle of the original pressing plate 12 at 23 201138597 (for example, about 10 degrees or less), the piston rod (pist〇nr〇d) The front end of the 〇2 touches the inner bottom of the cam slider 103 to decelerate the closing speed of the original pressing plate 12, thereby preventing the original pressing plate from falling rapidly. The other configuration is the same as that of the first embodiment, and therefore the description thereof will be omitted. Damping device In addition to the configuration shown in the drawings, a document pressing plate opening device of another configuration which is described in the specification of the present invention can be applied. The damper device 101 is, for example, an oil damper device or the like. The damper device 101 is not limited to a specific angle of the document pressing plate 2 (for example, about 10 degrees or less), and the angle of rotation of the document pressing plate 12 can be lowered. Further, the damper device 101 is preferably constituted by, for example, a cylinder (filler) 4 such as a filler (suieQnc) il) and a piston rod r〇d) which is elongated by exposing the length of the a cylinder 104, but is not limited thereto. this. The damper device of the second embodiment is an element of a conventional configuration, and therefore detailed description thereof will be omitted. Further, as another embodiment of the original plywood opening device, the lifting element is added with an elastic means formed by a compression screw (four) spring, or the elastic force of the elastic means may not be used, and the elastic member is thinly wound around the second shaft. The twisting material turns into a dynamic potential in a direction coincident with the supporting member. Further, as a member, in the embodiment, the lock member between the side plates connecting the lifting members is disposed on the side of the lift A member, and there is no special embodiment of the embodiment. For example, the body of the second rotating shaft on the side of the second rotating shaft of the lifting element may be reinforced, or the end of the elastic means formed by a shape-reducing helical spring assembled on the top plate may also be supported. The top plate-side of the movable end side of the standard 70 piece. In this situation 24 201138597 turned to the trend. The composition of Xia Wei's square document is above. Therefore, it can be applied to the assembly of the original "plywood" of the transaction machine to the device body and is suitable for the original plywood opening device and the opening of the original plywood.
