The original plywood opening device and the transaction machine having the original plywood opening device.

In the original plywood opening device in the above-mentioned transaction machine, since the original plywood is provided with an automatic document feeding device and has a certain weight, it is necessary to use a compressible coil spring which can eliminate the weight when performing the opening operation. However, since the compression coil spring itself has a non-uniform elastic force, and the elastic force also changes with long-term use, it is necessary to add an elastic force adjustment means for adjusting the compression coil spring.

The above-described elastic force adjusting means is mainly described in the description of Japanese Patent Publication No. 2002-202640 and Japanese Patent Publication No. 2004-101620, which uses a tool such as a screwdriver to rotate the adjusting member in the axial direction of the elastic means. Adjust the effective length of the elastic means to achieve the purpose of adjusting the elastic force. Wherein, the adjusting element is in contact with one end of the elastic means.

Further, in the case where the original plywood opening device B shown in Fig. 1 is provided with the compression coil springs being arranged side by side, the elastic force adjusting means D to be mounted have different sizes, but the basic configuration is the same. In this case, even if a plurality of elastic force adjusting means are not provided for the respective compression coil springs, the effect of the present invention can be attained by using only one elastic force adjusting means. However, in general, a plurality of elastic adjustment means are correspondingly provided for each compression coil spring.

Hereinafter, the original plywood opening device A and the elastic force are applied to the above-described first embodiment. The effect of the adjustment means D is explained.

In a state where the original pressing plate 3 is closed with respect to the apparatus body 2, as shown in FIG. 6, the compression coil spring 14 as an elastic means is compressed to the limit between the first spring receiving member 11 and the second spring receiving member 12. In this state, since the rotational moment generated by the original pressing plate 3 around the first hinge pin 9 by the supporting member 8 is greater than the moment generated by the elastic force, the original pressing plate 3 is crimped to the contact glass of the apparatus body 2. 2a. In other words, when the original belongs to an original having a small thickness, the original is in a state of being pressed against the contact glass 2a.

Then, when the front side of the original pressing plate 3 is held upward by the hand, the weight of the original pressing plate 3 minus the elastic force of the compression coil spring 14 is initially felt, and as the opening progresses, the compression is performed as an elastic means. The torque generated by the elastic force of the coil spring 14 is gradually increased, and the operator can open the original pressure plate without feeling the original weight of the original pressure plate 3, as shown in FIG. 9, even before and after the opening angle of 30 degrees, even if The hand is released from the original pressing plate 3 because the torque generated by the elastic force of the compression coil spring 14 and the moment generated around the first hinge pin 9 are balanced with each other, and the hinge friction force (not shown) The multiplication effect allows the original platen to remain open without falling naturally. At this time, the elastic force of the compression coil spring 14 acts on the lifting member 13 by the adjusting member 19 and the actuating member 17, which is greater than the rotation of the lifting member 13 by the weight of the original pressing plate 3 around the second hinge pin 10. Torque, so the original plywood 3 does not naturally rotate and cause it to hang down. Therefore, the operator can easily place the original on the contact glass 2a with both hands, and after the photocopying is completed, the original pressing plate 3 is opened to take out the original.

Generally, the opening angle of the original pressing plate 3 is approximately between 30 degrees and 60 degrees. If the opening angle exceeds 60 degrees, the sliding of the first spring bearing member 11 is prevented, the cam portion 11b and the pressure receiving member 16 start to move away from each other, and the original pressing plate 3 is pushed up by hand. As shown in Fig. 11, the original platen 3 can be opened to a maximum opening angle of 90 degrees. At the maximum opening angle of the original platen 3 at the 90 degree angle, the rear end portion of the support member 8 abuts against the rear end portion of the assembly member 4, so that the original pressing plate 3 remains stationary. When the original pressing plate 3 opened at 90 degrees is closed, when the original pressing plate 3 is closed to 60 degrees, the cam portion 11b of the first spring receiving member 11 is pressed against the pressing member 16, and the elastic force of the compression coil spring 14 starts to function. When the original pressing plate 3 is pushed down by both hands, it is closed downward against the elastic force of the compression coil spring 14, and when the closing angle of 30 degrees is reached, the rotational force generated by the original pressing plate 3 around the first hinge pin 9 is generated. The moment is greater than the elastic force of the compression coil spring 14, at which time the hands are released from the original platen 3, and the original platen 3 is quietly closed by its own weight.

If the original is a book-thick thick original, the original pressing plate 3 is opened to a necessary angle, and then a thick original 20 is placed on the contact glass 2a, and the original pressing plate 3 is to be closed, and the rear of the original pressing plate 3 is first When the corner of the thick original 20 is touched, and further pushing is pushed down, as shown in FIG. 10, the original pressing plate 3 together with the lifting member 13 resists the elastic force of the compression coil spring 14 and the second hinge pin 10 The fulcrum is reversed, whereby the original pressing plate 3 can be slightly horizontally covered on the thick original 20. Through the foregoing mechanism, external light can be prevented from entering the device body 2 by the contact glass 2a, effectively preventing the problem that the photocopy is not clear.

Further, when the elevating member 13 is reversed, as described above, the elevating member 13 is reversed with the second hinge pin 10 as a fulcrum. At this time, the actuating member 17 with the second hinge pin 10 as a fulcrum reverses. The second spring retaining member 12, which in turn compresses the compression coil spring 14, is finished after the photocopying is completed, and after the hand is separated from the original plywood 3, the original plywood 3 is compressed by the coil spring 14 by the second spring retaining member 12 and the adjusting member 19 And the actuating member 17 rotates the lifting member 13 so that the original pressing plate 3 can be automatically or the operator can easily return to the original position with a minimum force, so that the lifting member 13 returns to the state of being coincident with the supporting member 8 before the reverse rotation. .

When the elastic force of the compression coil spring 14 is adjusted by the elastic force adjusting means D, as shown in FIG. 11, after the original pressure plate 3 is opened, the head of the hexagonal hand (not shown) is inserted into the hexagonal hole 18d and Rotation in one of the left and right directions, as shown in Fig. 8, allows the adjustment member 19 to move in the radial direction of the actuating member 17, so that the operator can easily adjust the elastic force of the compression coil spring 14 on the front side of the transaction machine 1. Among them, the hexagonal hole 18d is provided at the head portion 18a of the adjusting screw 18.
