Of course, it is also possible to replace the riveting and use the E-ring and other locking rings.

Next, the operation of the document pressing plate opening device 1A will be described.

First, as shown in Figures 3 and 8, in a transaction machine such as a photocopier The state in which the machine main body 1a of the machine 1 closes the original pressing plate 18 is such that the original pressing plate 18 is pressed against the contact glass 1b with its weight, and in the case of a thin original, the thin original is pressed against the contact glass 1b. on. Further, when the original plate opening device 1A is closed, particularly as shown in Fig. 8, the slider housing 4, the upper arm member 6, the lower arm member 7, and the supporting member 8 are in a state of being overlapped with each other with respect to the assembly member 2.

Next, in order to open the original pressure-bonding plate 18 from the closed state, the hand is placed on the handle portion 18b (shown in FIG. 1) on the current side of the original pressure-sensitive adhesive plate 18 to raise it upward, firstly ascending and descending. The mechanism R is operated by the selection operation means S, and as shown in FIGS. 4 and 9, the original pressing plate 18 is horizontally raised with respect to the contact glass 1b.

In other words, when the hand is placed on the handle portion 18b of the current side to rise upward, the support member 8 and the link arms 12 and 12, the upper arm member 6 and the lower arm member 7 of the link mechanism L constituting the lift mechanism R are used. Since the supporting member 8 is horizontally raised with respect to the contact glass 1b, the original pressing plate 18 provided on the supporting member 8 is also raised in a horizontal state. That is, when the hand is placed on the current side of the original pressing plate 18 to rise upward, as shown in FIGS. 8 and 9, the connecting arms 12 and 12 are first inserted into the guide grooves 2i, 2i of the assembling member 2. The rollers 17 and 17 of the guide grooves 2g and 2g are raised while rotating in the right direction, and the upper arm member 6 and the lower arm member 7 are rotated in the right direction in the drawing, whereby the support member 8 is moved by the first lifting shaft When the rod 13 and the second elevating shaft 14 are rotated in the left direction, as shown in FIGS. 4 and 9, the document pressing plate 18 is raised in a horizontally maintained state with respect to the contact glass 1b. Next, the elastic means 5 at a specific rising position When the weight of the original pressing plate 18 is balanced, even if the original pressing plate 18 is separated from the hand, it does not naturally fall, and the horizontal opening state can be maintained.

When the original pressing plate 18 is raised to a certain height in a horizontal state, the rollers 17 and 17 fitted into the first guide grooves 2g and 2g reach the intersections 2j and 2j of the first guide grooves 2g and 2g and the second guide grooves 2h and 2h. At this time, the rising operation of the original pressing plate 18 in the horizontal state ends.

In this horizontally rising state, when the current side of the original pressure plate 18 is further raised upward, the system opening mechanism K is operated by the selection operation means S. That is, the upper arm member 6 receives the force for rotating in the right direction with the spindle shaft 10 as the fulcrum, and the rollers 17 and 17 are fitted into the second guide grooves 2h and 2h of the guide grooves 2i and 2i, and the upper arm member 6 is allowed to rotate in the right direction. Therefore, the original pressing plate 18 is maintained at a horizontal level and rotated together with the supporting member 8. As shown in Figs. 5 and 10, the original pressing plate 18 and the supporting member 8 are simultaneously rotated by the main shaft 10 as a fulcrum. As a result, the elastic force of the elastic means 5 acts on the supporting member 8 by the slider housing 4, so that the original pressing plate 18 does not feel its weight and is opened, and the elastic force of the elastic means 5 is balanced with the weight of the original pressing plate 18. At this time, even if the original pressure plate 18 is released from the hand, it does not naturally fall and close.

Therefore, the rotational moment of the original pressing plate 18 is balanced with the elastic force of the elastic means 5 at a specific opening angle range, and therefore, even if the hand is separated from the original pressing plate 18, the opening angle can be naturally dropped, and the contact glass 1b can be used with both hands. Load or replace the original.

In the beginning, the original pressing plate 18 can be kept open with one hand and the original can be replaced with the other hand.

When the original is placed on the contact glass 1b, or the original is photocopied to be removed from the contact glass 1b, and the handle portion 18b on the current side of the original pressing plate 18 is pressed downward by hand, the lifting mechanism R is connected by the mechanism L does not operate, and the rollers 17, 17 are rotated in the opposite directions in the second guide grooves 2h, 2h, and the original pressing plate 18 is closed to the original horizontal state by the opening mechanism K. As shown in FIGS. 4 and 9, when returning to the horizontal state at the time of ascending, the elevating mechanism R is operated this time, and the document pressing plate 18 is closed with respect to the contact glass 1b in a horizontal state.

Therefore, as shown in FIGS. 4 and 9, when there is a thin original to be photocopied on the contact glass 1b, even if the original pressing plate 18 is closed, the original pressing plate 18 is closed in a horizontal state, thereby preventing the oblique side from coming. The wind is in contact with the thin original to produce a positional shift.

On the other hand, in the case where the original is a thick original G as thick as a book, the original pressing plate 18 is in a horizontal state and is in a raised state, and the thick original G is placed on the contact glass 1b to close the original pressing plate 18. When the original pressing plate 18 is closed horizontally, it is not necessary to reverse the original pressing plate as the conventional technique resists the elastic force of the elastic means, so that unnecessary force is not required, thereby improving the operability, and it is not necessary Applying unnecessary pressure on the contact glass.

12 is a view showing a state in which the original pressing plate 18 is further opened, and even if the original pressing plate 18 is opened in this way, the rear portion of the original pressing plate 18 does not need to protrude toward the rear of the transaction machine 1, and therefore, when the transaction machine is set to the wall, Omit the space at the back.

As described above, the original plywood opening device of the present invention is used as Open the original platen of a business machine such as a photocopier, a printing machine, or a list machine, or an opening device of an original press plate of a so-called multifunction machine having various functions such as a list machine, a facsimile machine, a scanner, and the like. It is also suitably used as a transaction machine to which the original plywood opening device of the present invention is applied.
