The upper plate 31, the side plates 32, and the holding plate 33 constitute a housing portion 34 of a cam slider or an elastic means to be described later.

One end portion (rear end portion) of the side plates 32 of the support member 3 is provided with a second shaft hole 38 that is inserted through the second shaft 17 and is provided with recesses 35a, 35b so that the actuating member 18 described later is provided. And the connection means 9 of the connection mechanism 6 enters. The other end portion (front end portion) of the both side plates 32 is further provided with a shaft insertion hole 36 of the first shaft 15 . When the shaft insertion holes 36 of the side plates 32 of the support member 3 are brought together with the bearing holes 26a of the bearing members 26 of the side plates 22 of the assembly member 2, the shaft insertion holes 36 and the bearing members 26 are supported.

The elevating member 4 is configured such that even a thick original as thick as a book can be stably pressed against the upper surface of the machine body 11a by the original pressing plate 12, so that the upper surface of the thick original can be horizontally covered. The lifting member 4 is composed of an upper plate 41, two side plates 42 and an assembly plate 44 of the original pressing plate 12 to cover the supporting member 3 from the upper side, wherein the side plates 42 are perpendicular to the upper plate 41 from both end portions of the upper plate 41, respectively. The direction (also including a slight vertical direction) extends, and the assembly plate 44 is bent at right angles from the lower end side of the both side plates 42 outward. From the center of one end portion (rear end portion) of the lifting member 4 to the upper plate 41 The second shaft insertion hole 43 is provided at one side, and the other end of the second shaft insertion hole 43 and the side opposite to the upper plate 41 side are provided with an actuating element assembly for inserting the actuating member 18.

When the second shaft insertion hole 43 of the two side plates 42 of the lifting member 4 is brought together with the second shaft hole 38 of the side plates 32 of the support member 3, the second shaft 17 is inserted through the holes, thereby lifting the member 4 and the support member 3 are rotatably coupled to each other with the second shaft 17 as an axis. Moreover, if the actuating element is assembled to the side of the elevating element 4, it may not be pin-shaped. Further, in Fig. 5, the reference numeral 39 is a spacer.

In the embodiment, the elastic means 5 causes the original pressing plate 12 to rotate in a dynamic direction in the opening direction, and pushes the lifting element 4 in a direction overlapping the supporting member 3, and when the original pressing plate 12 is below an arbitrary rotation angle, The elastic force that pushes the original pressing plate 12 becomes smaller than the torque of the original pressing plate 12. Further, the opening direction of the present invention is such that the original pressing plate 12 is away from the contact glass 13 when the original pressing plate 12 is rotated. In the present invention, the closing direction is the direction opposite to the opening direction, and the original pressing plate 12 is brought close to the direction of the contact glass 13 when the original pressing plate is rotated. The angle of rotation of the present invention is the angle of the original platen 12 relative to the surface of the contact glass 13 above the machine body 11a. The arbitrary rotation angle in the present invention is an angle arbitrarily set by the urging force of the elastic means 5, for example, by the elastic means 5 such that the urging force for pushing the original pressing plate 12 is smaller than the angle of the torque of the original pressing plate 12.

The elastic means 5 is not particularly limited, and is, for example, a compression coil spring 53. The compression coil spring 53 is housed in the support member 3 and is elastically disposed between the actuating member 18 and the pressure receiving means 16. A spring bearing member 51 is provided between the compression coil spring 53 and the actuating member 18. The spring bearing member 51 has a receiving recess 51a of the elastic means 5, and a cam slider 52 is provided between the pressing means 16 of the compression coil spring 53. Further, as will be described later, the spring receiving member 51 may be omitted by arranging the top plate on the member of the supporting member 3. Further, the component symbol 52a is a housing portion of the elastic means 5.

The compression coil spring 53 is not particularly limited in number, and one or two or more may be used, and the compression coil spring 53 urges the spring bearing member 51 and the cam slider 52 toward the members away from each other. The compression coil spring 53 causes the original pressing plate 12 to rotate in the opening direction, and when the original pressing plate 12 is below a predetermined rotation angle (for example, 15 degrees (including about 15 degrees)), the elastic force of the original pressing plate 12 is generated. The force of the turning dynamic potential becomes smaller than the turning torque of the original pressing plate 12. Further, the compression coil spring 53 may be provided in two or three layers and overlapped in the radial direction and the axial direction.

The spring bearing member 51 and the cam slider 52 are formed in a cylindrical shape having a rectangular cross section and a bottom. When the spring receiving member 51 and the cam slider 52 are in the respective opening portions, when the receiving recessed portion 51a and the accommodating portion 52a are opposed to each other, the compression coil spring 53 is placed between the components, and each of them is capable of being capable of being placed between the components. It is accommodated in a state of being slidably fitted to the accommodating portion 34 of the support member 3. When the spring bearing member 51 and the cam slider 52 are slightly parallel to the bottom plate 21 of the assembly member 2 and the supporting member 3 (upper plate 31) (for example, when the original pressing plate 12 is in close contact with the contact glass 13 above the machine body 11a) (original plywood 12 is formed in the closed position)) in a length accommodated in the accommodating portion 34 of the support member 3.

The spring bearing member 51 is a member that pushes the actuating member 18 by the urging force of the compression coil spring 53, and pushes the original pressing plate 12 toward the opening direction when the supporting member 3 and the lifting member 4 are superposed and pushed. That is, the upper plate 41 of the elevating member 4 is brought into contact with or approaches the upper plate 31 of the support member 3 by the urging force of the compression coil spring 53. At this time, the upper plate 41 is preferably, for example, slightly parallel to the contact glass 13.

The outer surface of the bottom portion (sometimes referred to as the occluding portion) of the cam slider 52 is provided with an inclined cam portion 56 and is pressed against the pressure receiving means 16. When the original pressing plate 12 (refer to FIG. 3) at the closed position is rotated in the direction away from the contact glass 13 (upward) with the first rotating shaft 15 as the axis, the place where the pressing means 16 is pressed will be inclined from the projection 56a. The portion 56b is slid and moved slowly, and the cam slider 52 is slid by pressing the compression coil spring 53 in the support member 3 toward the rear end portion, and the compression coil spring 53 is slowly elongated.

The connecting mechanism 6 is disposed on both sides of the supporting member 3, and is composed of a first connecting arm 7, a second connecting arm 8, a connecting means 9, and a cam means 10, wherein the first connecting arm 7 is a pair and each end portion thereof The rotatable shaft is supported on both ends of the first shaft 15 , and the second connecting arm 8 is also a pair, and each end portion thereof is rotatably supported at both ends of the second shaft 17 , and the connecting means 9 is a pair. And connecting the pair of first connecting arms 7 and the movable ends of the pair of second connecting arms 8 , the cam means 10 is a pair, and the first cam element 19 and the cam slider 52 provided by the connecting means 9 The second cam member 54 provided on both sides is formed. Moreover, the connection mechanism 6 is a pair of first The connecting arm 7, the pair of second connecting arms 8, the pair of connecting means 9, and the pair of cam means 10 are constituted, but only one of them may be constituted. Further, the reference numeral 7b is a connecting hole of the connecting means 9, the reference numeral 8a is a washer, and the reference numerals 8b and 8c are connecting holes of the actuating element 18 and the connecting means 9.

The connecting means 9 connects the connecting rods 14 on the respective movable end sides of the first connecting arm 7 and the second connecting arm 8, and the deforming shaft portion 14a of the connecting rod 14 is inserted into and engaged with the deforming assembling hole 7a of the first connecting arm 7. At the same time, the deformed shaft portion 14a is inserted into and engaged with the deformation assembling hole 19a of the first cam member 19, and is further fixed by the fixing pin 19b.

Hereinafter, the operation and effect of the document puncture plate opening device of the present invention and the transaction machine to which the original plywood opening device is applied will be described.

As shown in FIG. 3, FIG. 6, and FIG. 9, when the document pressing plate 12 is closed and pressed against the contact glass 13 of the scanning portion of the machine body 11a, the original pressure plate 12 is subtracted from the weight of the original by the coil spring. A thin original (not shown) is pressed against the contact glass 13 by the force of the force of the dynamic force. Further, here, the document pressing plate 12 may be formed to have its own weight, and the original platen opening device 1A may be turned in a dynamic direction in the pressing direction. In this closed state, the elastic means 5 is in the maximum compression state. Further, the first cam element 19 and the second cam element 54 of the cam means 10 of the coupling mechanism 6 are in a state of being in contact with each other.

Then, in order to open the original pressing plate 12, when the handle portion 12a provided on the current side thereof is held in the opening direction by hand, the original pressing plate 12 and the lifting member 4 and the supporting member 3 are simultaneously opened by the original pressing plate. The first shaft 15 of 1A is opened for pivotal rotation. However, at this time, the support element The member 3 rotates in the opening direction with the first shaft 15 as a fulcrum, but the first link arm 7 and the second link arm 8 of the link mechanism 6 press the first cam member 19 against the cam slider 52. The two cam members 54 are configured to pull the lifting member 4 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. Therefore, the lifting member 4 is pivoted by the second rotating shaft 17 As a result of the rotation of the support member 3 in the opposite direction of rotation, as shown in Figs. 7, 10 and 11, the original press plate 12 assembled to the elevating member 4 is opened in the vertical direction with respect to the contact glass while being held horizontal. As shown in FIG. 7 and FIG. 11, the original platen 12 is opened in a horizontal state in this horizontal state, and the rotation angle of the support member 3 is 30 degrees. When the angle is exceeded, the cam member 10 of the joint mechanism 6 lifts the component 4 The direction of rotation is opposite to that of the previous one, and becomes coincident with the support member 3. Therefore, as shown in FIGS. 8 and 13, in the open position of 60 degrees, the original plywood 12 is then overlapped with the support member 3, and then The status is on. Therefore, in the fully open state shown in Fig. 1, the rear portion of the original pressing plate 12 does not have to protrude toward the rear of the machine body 11a. This feature is different from the invention of Patent Document 3.

Next, when the opened original document pressing plate 12 is closed, as shown in FIGS. 8 and 13, the closing angle is 60 degrees, and the lifting member 4 and the original pressing plate 12 are overlapped with the supporting member 3, and simultaneously with the supporting member 3 Turn and close. Next, when the closing angle is 60 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 FIGS. 7 and 10 As shown in FIG. 11, the original pressing plate 12 is reversed by the first connecting arm 7 and the second connecting arm 8 By this, the contact glass 13 is closed in the vertical direction while maintaining the horizontal state.

Therefore, the original pressing plate 12 is closed in a horizontal state with respect to the contact glass 13, and therefore, the offset with respect to the thin original on the contact glass 13 can be effectively prevented by the wind pressure.

Further, as shown in FIG. 7 and FIG. 11, the thick original D is thicker than the book, and is closed. Therefore, it is not necessary to cover the upper surface of the original pressing plate 12 horizontally compared to the conventional device. The elastic force against the elastic means 5 reverses the original pressing plate, so that it is unnecessary to apply unnecessary force to the contact glass 13 and the thick original D.

[Second embodiment]

Fig. 14 is a view showing another embodiment of the original plywood opening device. According to the illustration, a damper 101 of a conventional configuration is provided in the compression coil spring 100 of the original plate opening device 1C of the second embodiment. When the document pressing plate 12 is rotated in the closing direction, the damper device 101 touches only the front end of the piston rod 102 only below a certain rotation angle below the arbitrary rotation angle of the original pressing plate 12 (for example, about 10 degrees or less). The inner bottom portion of the cam slider 103 is connected to decelerate the closing speed of the original pressing plate 12 to prevent the original pressing plate from falling rapidly. The other configuration is the same as that of the first embodiment, and thus the description thereof is omitted. The damper device may be adapted to the embossed plate opening device of another configuration described in the specification of the present invention, in addition to the configuration shown in FIG.

The damper device 101 is, for example, an oil damper device or the like. This damper device 101 is only below a certain angle of the original platen 12 (for example, about 10 degrees or less), the rotation angle of the document pressing plate 12 can be reduced, and is not particularly limited. Further, the damper device 101 is preferably constituted by, for example, a cylinder 104 filled with silicone oil or the like and a piston rod which is pushed by exposing the cylinder 104 to a long length, but is not limited thereto. The damper device 101 of the second embodiment is an element of a conventional configuration, and thus detailed description thereof will be omitted.

Further, as another embodiment of the original plywood opening device, the elevating member is provided with an elastic means formed by a compression coil spring, or the elastic force of the elastic means may be disabled, and is surrounded by the second shaft. The torsion coil spring rotates in a direction that coincides with the support member.
