It is also possible to replace the riveting with the E-ring and its + then 'for the operation of the above-mentioned original dust-proof plate opening device 15 201209299 First, as shown in FIGS. 3 and 8 , in a transaction machine 1 such as a relative photocopier The state in which the main body la is closed to the original (four) plywood 18 is such that the original ply 18 is pressed against the contact glass lb by its weight, and in the case of a thin original, the thin original is pressed against the contact glass lb. Further, when the original plywood opening device 1A is closed, particularly as shown in Fig. 8, the slider casing 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 assembling member 2. In order to open the original pressure plate 18 from the closed state, the handle is placed on the current side of the original pressure plate 18 (shown in FIG. As shown in Fig. 4 and Fig. 9, the document pressing plate 18 is horizontally raised with respect to the contact glass lb by the selection operation means S, and the hand is placed on the handle portion 8b of the current side. When rising upward, the upper arm member 6 and the lower arm member 7 are cooperatively operated by the support member 8 and the connecting arms 12 and 12 constituting the connecting mechanism L· of the elevating mechanism R. Therefore, the supporting member 8 is in contact with the glass lb level. When the ground is raised, the original platen 18 which is provided on the support member 8 is also raised in the horizontal state, and the hand is placed on the current side of the original pressure plate 18 to rise upwards as shown in FIG. 8 and FIG. The arms 12 and 12 are raised while rotating in the right direction via the rollers j 7 and 17 of the first guide grooves 2g and 2g of the guide grooves 2, 2 1 of the component 2, and the upper arm member <5 and lower arm member are raised. 7 turn to the right in the figure, thereby The support member 8 is rotated in the left direction by the first lifting shaft 13 and the second lifting shaft 14, whereby the original pressing plate 18 is in contact with the glass lb 16 201209299 at the maintenance level as shown in FIGS. 4 and 9 . Then, when the weight of the original plate 18 is balanced, the position elastic means 5, the original pressing plate 18 is released from the hand, and the horizontal pressing state is maintained. The first plate 18 is raised to the horizontal state to the horizontal state. At a certain height, the intersecting portions 2j, 2j'g, 2g& U of the second guide grooves 2h and 2h in which the rollers 17 and 17 of the first guide grooves 2g and 2g are fitted are finished in the horizontal_upward operation. The slabs of the slabs and the slabs of the slabs of the slabs of the slabs of the slabs of the slabs of the original slabs of the original slabs The upper arm member 6 is allowed to rotate in the right direction. Therefore, = 'the height at which the plate is maintained at the horizontal state is rotated together with the support member 8, as shown in Figs. 5 and 10, the original splicing plate 18 and the branch member 8 are simultaneously The car is opened by the lever 10 as a pivot. So - come, elastic The hand=force acts on the support member 8 by the slider housing 4, so that the original: does not feel its weight and is opened, and the elastic means 5 balances the weight of the pressure plate 18 even if the hand is released from the original 'pressure 5 plate 18, it will not fall naturally and close. The rotation torque of the dust-receiving board 18 is balanced by the elastic force of the specific opening angle, so even if the hand is left away from the original, it will not be used naturally. At the angle, the original can be placed or replaced with the contact glass lb. At the beginning, the original overlap plate 8 can be held by the hand of the side of the 2012 201200, and the original can be replaced with the other hand. When the original is placed on the contact glass lb, or the original is photocopied and the original is removed from the contact glass lb, and the original dust is removed by hand to reverse the front portion 18b of the front side, by the connection mechanism The L lifting mechanism R does not move the rollers 17, 17 in the second guiding groove, and rotates in the opposite direction in the second direction, and the original dusting plate 18 is closed to the original horizontal state by the opening mechanism K. As shown in Fig. 4 and Fig. 9, when returning to the horizontal state at the time of ascending, this time, the elevating mechanism R operates the original platen 8 to be closed with respect to the contact glass 1b in the horizontal state. Therefore, as shown in FIG. 4 and FIG. 9, when the contact glass lfc) is to be photocopied, 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 being slanted. The incoming wind is in contact with the thin original to cause 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 lb_original pressing plate 18 The original platen is closed horizontally, so that 'there is no need to reverse the original dustboard as the conventional technique resists the elastic force of the elastic means', so that it is unnecessary to use unnecessary force, thereby improving the operability, and does not need to The contact glass exerts an unnecessary pressure on the contact glass. Fig. 12 shows a state in which the original pressing plate ι8 is not opened, and even if the original pressing plate 18 is opened, the rear portion of the original pressing plate 18 is protruded toward the rear of the transaction machine 1. Therefore, the transaction machine is set to the wall. When you can omit the space in the back. 18 201209299 As explained above, the original plywood of the present invention opens the photocopier, and prints it as * (4) the original plywood of the (4) dereliction of duty or occupational scales, 2 the heart-printing function has other list machines, faxes It is also useful as a business machine to which the original plywood opening device of the present invention is applied, such as a retracting device for a document pressing plate of a transaction machine of a machine or a scanner, and the like.
