[0060] Hereinafter, with reference to FIGS. 1 to 14, a specific configuration of an automated teller machine 1 according to a first embodiment of the present disclosure will be described. A medium 2-1, such as a banknote, can be deposited into the automated teller machine 1. Further, a bundle of media 2 (see FIG. 9) in which multiple media 2-1 are stacked can be deposited into the automated teller machine 1. While separating the deposited bundled media 2 into individual sheets and transferring the individual sheets, the automated teller machine 1 can discriminate the media 2-1, and can classify and store the media 2-1 or return the media 2-1 to a user (not shown) based on the discrimination results. In addition, the automated teller machine 1 can transfer the stored media 2-1 for withdrawal by a user. The automated teller machine 1 may include a deposit and withdrawal unit 100, a discrimination unit 200, a storage unit 300, a medium replenishment unit 400, a conveyance path 500, a sheet transfer unit 600, and a controller 700.

[0061] Referring to FIGS. 2 and 3, a medium 2-1 such as banknotes can be deposited and withdrawn through the deposit and withdrawal unit 100. The deposit and withdrawal unit 100 may be configured so that, when media 2-1 are deposited, they can be deposited as a bundle of media 2 in which multiple media 2-1 are stacked. The bundle of media 2 may be deposited horizontally longitudinally in the deposit and withdrawal unit 100. In other words, the bundle of media 2 may be deposited horizontally along its longer longitudinal dimension in the deposit and withdrawal unit 100. The deposit and withdrawal unit 100 may have a first entry and exit port 100a and a second entry and exit port 100b. The first entry and exit port 100a may be a deposit-only port, and the bundle of media 2 may be deposited in the first entry and exit port 100a. The second entry and exit port 100b may be a withdrawal-only port, and a medium 2-1 may be withdrawn therethrough. The deposit and withdrawal unit 100 may include a push plate unit 110, a first pickup roller 120, a second pickup roller 130, a first lifting and lowering drive unit 140, a second lifting and lowering drive unit 150, a first medium detection sensor 160, a second medium detection sensor 170, a transfer assistance roller 180, and a friction member 190.

[0062] A bundle of media 2 may be placed on the push plate unit 110. The push plate unit 110 may extend in a deposit direction toward the discrimination unit 200. The bundle of media 2 may be placed on the push plate unit 110 by a user (not shown) through the first entry and exit port 100a. For example, the bundle of media 2 may be placed on an upper surface of the push plate unit 110. The push plate unit 110 may be raised and lowered by the second lifting and lowering drive unit 150.

[0063] The first pickup roller 120 can transfer the bundle of media 2 in the deposit direction when the bundle of media 2 is placed on the push plate unit 110. The first pickup roller 120 works together with the transfer assistance roller 180 to move the bundle of media 2 in the deposit direction. The first pickup roller 120 is disposed above the push plate unit 110 and can be raised and lowered by the first lifting and lowering drive unit 140. In addition, the first pickup roller 120 can be rotated by a roller rotation drive unit 650 included in the sheet transfer unit 600 to be described later. The first pickup roller 120 may be arranged closer to the first entry and exit port 100a than the second pickup roller 130. The second pickup roller 130 can transfer a medium 2-1 from the bundle of media 2 in the deposit direction. The second pickup roller 130 can transfer the medium 2-1 from the bundle of media 2 transferred in the deposit direction from the push plate unit 110 by the first pickup roller 120 in the deposit direction. The second pickup roller 130 may be disposed to be spaced apart from the first pickup roller 120 in the deposit direction. The second pickup roller 130 may be disposed farther from the first entry and exit port 100a than the first pickup roller 120. The second pickup roller 130 is disposed above the push plate unit 110 and can be raised and lowered by the second lifting and lowering drive unit 150. In addition, the second pickup roller 130 can be rotated by the roller rotation drive unit 650.

[0064] Referring to FIGS. 4 and 5, the first lifting and lowering drive unit 140 can lift and lower the first pickup roller 120. The first pickup roller 120 may not contact or may come into contact with the bundle of media 2 placed on the push plate unit 110 due to the lifting or lowering of the first pickup roller 120 by the first lifting and lowering drive unit 140. In other words, when the first pickup roller 120 is raised by the first lifting and lowering drive unit 140, the first pickup roller 120 may not come into contact with the bundle of media 2 placed on the push plate unit 110. In addition, when the first pickup roller 120 is lowered by the first lifting and lowering drive unit 140, the first pickup roller 120 may come into contact with the bundle of media 2 placed on the push plate unit 110. The first lifting and lowering drive unit 140 may be connected to the controller 700 and controlled by the controller 700. The first lifting and lowering drive unit 140 may include a first lifting and lowering support arm 141, a lifting and lowering link 142, and a link drive cylinder 143.

[0065] The first pickup roller 120 may be rotatably supported by one side of the first lifting and lowering support arm 141. In addition, the other side of the first lifting and lowering support arm 141 may be configured to be rotatable about a first arm rotation center. As the other side of the first lifting and lowering support arm 141 rotates about the first arm rotation center, the first pickup roller 120 may be raised/lowered. For example, the first arm rotation center may be the same as a rotation center CF of a feed roller 610 included in the sheet transfer unit 600, which will be described later. In other words, the other side of the first lifting and lowering support arm 141 may be rotatably disposed on a rotation shaft of the feed roller 610.

[0066] The lifting and lowering link 142 may be connected to the first lifting and lowering support arm 141. A plurality of lifting and lowering links 142 may be provided. In addition, the plurality of lifting and lowering links 142 are connected to each other, and any one of the plurality of lifting and lowering links 142 may be connected to the first lifting and lowering support arm 141. Further, another one of the plurality of lifting and lowering links 142 may be connected to the link drive cylinder 143.

[0067] The link drive cylinder 143 can drive the lifting and lowering link 142. By driving the lifting and lowering link 142 by the link drive cylinder 143, the other side of the first lifting and lowering support arm 141 can rotate about the first arm rotation center, and the first pickup roller 120 can be raised or lowered. The link drive cylinder 143 may be connected to the lifting and lowering link 142. A cylinder rod of the link drive cylinder 143 may be connected to the lifting and lowering link 142. In the case where a plurality of lifting and lowering links 142 are provided, the link drive cylinder 143 may be connected to one of the lifting and lowering links 142 except for the lifting and lowering link 142 connected to the first lifting and lowering support arm 141 among the plurality of lifting and lowering links 142. The link drive cylinder 143 may be connected to and controlled by the controller 700.

[0068] Referring to FIGS. 6 to 8, the second lifting and lowering drive unit 150 can lift and lower the second pickup roller 130. The second pickup roller 130 may not contact or may come into contact with the bundle of media 2 on the push plate unit 110 due to the lifting or lowering of the second pickup roller 130 by the second lifting and lowering drive unit 150. In other words, when the second pickup roller 130 is raised by the second lifting and lowering drive unit 150, the second pickup roller 130 may not come into contact with the bundle of media 2 placed on the push plate unit 110. In addition, when the second pickup roller 130 is lowered by the second lifting and lowering drive unit 150, the second pickup roller 130 can come into contact with the bundle of media 2 placed on the push plate unit 110. The second lifting and lowering drive unit 150 may be configured to raise/lower the push plate unit 110 while raising/lowering the second pickup roller 130. The lifting/lowering of the push plate unit 110 by the second lifting and lowering drive unit 150 can cause the push plate unit 110 to come closer to the first pickup roller 120 and the second pickup roller 130 or to move away from the first pickup roller 120 and the second pickup roller 130. The second lifting and lowering drive unit 150 may be connected to and controlled by the controller 700. The second lifting and lowering drive unit 150 may include a second lifting and lowering support arm 151, a lifting and lowering cam 152, a stopper 153, an arm lifting and lowering gear 154, a lifting and lowering drive motor 155, a torque limiter 156, a rack gear 157, a pinion gear 158, and a plate lifting and lowering gear 159.

[0069] The second pickup roller 130 may be rotatably supported by one side of the second lifting and lowering support arm 151. In addition, the other side of the second lifting and lowering support arm 151 may be configured to be rotatable about a second arm rotation center. As the other side of the second lifting and lowering support arm 151 rotates about the second arm rotation center, the second pickup roller 130 may be raised or lowered. For example, the second arm rotation center may be the same as the rotation center of the feed roller 610. In other words, the other side of the first lifting and lowering support arm 141 may be rotatably disposed on the rotation shaft of the feed roller 610.

[0070] The lifting and lowering cam 152 can lift and lower the second lifting and lowering support arm 151. The lifting and lowering cam 152 can be rotated, and the second lifting and lowering support arm 151 can be moved up or down depending on the rotational position of the lifting and lowering cam 152. The lifting and lowering cam 152 may have a stopper engagement portion 152-1 that moves along the stopper 153. In addition, the rotation range of the lifting and lowering cam 152 can be limited by the stopper 153 and the stopper engagement portion 152-1. In other words, the lifting and lowering cam 152 can be rotated within a predetermined rotation range.

[0071] The stopper 153 can limit the rotation range of the lifting and lowering cam 152. In other words, the stopper 153 can limit the lifting and lowering cam 152 to rotate within the predetermined rotation range. For example, the stopper 153 may have an arc shape and may be a groove into which the stopper engagement portion 152-1 of the lifting and lowering cam 152 can be inserted.

[0072] The arm lifting and lowering gear 154 can transmit rotational force of the lifting and lowering drive motor 155. A plurality of arm lifting and lowering gears 154 may be provided. The plurality of arm lifting and lowering gears 154 are meshed with each other, and one of the plurality of arm lifting and lowering gears 154 may be connected to the lifting and lowering cam 152 and another one may be connected to the lifting and lowering drive motor 155. One of the plurality of arm lifting and lowering gears 154 may be connected to a rotation shaft of the lifting and lowering cam 152 and another one may be connected to a rotation shaft of the lifting and lowering drive motor 155. In addition, any two of the plurality of arm lifting and lowering gears 154 that are not connected to the lifting and lowering cam 152 and the lifting and lowering drive motor 155 may be connected to the torque limiter 156.

[0073] The lifting and lowering drive motor 155 can provide rotational force. The lifting and lowering drive motor 155 can provide rotational force to rotate the lifting and lowering cam 152 so that the second lifting and lowering support arm 151 moves up or down. In addition, the lifting and lowering drive motor 155 can provide rotational force to rotate the pinion gear 158 so that the push plate unit 110 is raised or lowered. The lifting and lowering drive motor 155 may be connected to one of the plurality of arm lifting and lowering gears 154. The lifting and lowering drive motor 155 may be connected to one of the plurality of arm lifting and lowering gears 154 excluding the arm lifting and lowering gear 154 connected to the lifting and lowering cam 152 among the plurality of arm lifting and lowering gears 154. The ascending and descending drive motor 155 may be connected to and controlled by the controller 700.

[0074] The torque limiter 156 may be configured to allow the second lifting and lowering drive unit 150 to operate to raise the push plate unit 110 in a state where the lowering of the second pickup roller 130 has been completed, or to lower the second pickup roller 130 in a state where the lifting of the push plate unit 110 has been completed. In other words, the torque limiter 156 may allow the second lifting and lowering drive unit 150 to raise or lower the push plate unit 110 while raising or lowering the second pickup roller 130. In addition, even if the rotation range of the lifting and lowering cam 152 is limited by the stopper 153, the torque limiter 156 may allow the pinion gear 158 to rotate. The torque limiter 156 may be connected to any two of the plurality of arm lifting and lowering gears 154. Further, the torque limiter 156 may be connected to the plate lifting and lowering gear 159.

[0075] The rack gear 157 can work together with the pinion gear 158 to raise and lower the push plate unit 110. The rack gear 157 may be disposed on the push plate unit 110. The rack gear 157 may be disposed on the push plate unit 110 to extend in the lifting and lowering direction of the push plate unit 110.

[0076] The pinion gear 158 can work together with the rack gear 157 to raise and lower the push plate unit 110. The pinion gear 158 may be meshed with the rack gear 157 to move along the rack gear 157.

[0077] The plate lifting and lowering gear 159 can transmit the rotational force of the lifting and lowering drive motor 155 transmitted through the torque limiter 156 to the pinion gear 158. The plate lifting and lowering gear 159 may be connected to the pinion gear 158 and the torque limiter 156. The plate lifting and lowering gear 159 may be connected to a rotation shaft of the pinion gear 158.

[0078] Referring again to FIG. 3, the first medium detection sensor 160 can detect whether the bundle of media 2 has reached a region directly above the push plate unit 110. The first medium detection sensor 160 may be disposed on the push plate unit 110. The first medium detection sensor 160 may be positioned on the push plate unit 110 between the first pickup roller 120 and the second pickup roller 130. The first medium detection sensor 160 may be connected to the controller 700 and transmit information to indicate whether the bundle of media 2 has reached a region directly above the push plate unit 110 to the controller 700.

[0079] The second medium detection sensor 170 may be disposed to be spaced apart from the first medium detection sensor 160 in the deposit direction to detect the bundle of media 2. The second medium detection sensor 170 may be disposed on the push plate unit 110 to be spaced apart from the first medium detection sensor 160 in the deposit direction. In other words, the second medium detection sensor 170 may be disposed on the push plate unit 110 farther from the first entry and exit port 100a than the first medium detection sensor 160. In addition, the second medium detection sensor 170 may be disposed on the push plate unit 110 closer to the discrimination unit 200 than the first medium detection sensor 160. The second medium detection sensor 170 may be disposed on the push plate unit 110 to be spaced apart from the second pickup roller 130 in the deposit direction. The first medium detection sensor 160 may be connected to the controller 700 and transmit detection signals to the controller 700 when it detects the bundle of media 2.

[0080] The transfer assistance roller 180 can work together with the first pickup roller 120 to transfer the bundle of media 2 in the deposit direction. The transfer assistance roller 180 may be rotatably disposed below the first pickup roller 120 so as not to interfere with the lifting or lowering of the push plate unit 110.

[0081] The friction member 190 can apply frictional force to the lower medium 2-1 in the bundle of media 2 placed on the push plate unit 110. The friction member 190 may be disposed on the push plate unit 110 below the second pickup roller 130. In addition, the friction member 190 may be disposed on the push plate unit 110 between the first medium detection sensor 160 and the second medium detection sensor 170. By the frictional force applied by the friction member 190 to the lowermost medium 2-1 in the bundle of media 2 placed on the push plate unit 110, the lower medium 2-1 in the bundle of media 2 can be prevented from being dragged by the upper medium 2-1 that is moved in the deposit direction by the second pickup roller 130. In other words, even if the upper medium 2-1 of the bundle of media 2 is moved in the deposit direction by the second pickup roller 130, the lower medium 2-1 may not be moved in the deposit direction. At least a portion of the friction member 190, which comes into contact with the medium 2-1, is formed of a material with a friction coefficient greater than that of the medium 2-1, which allows it to apply friction to the lower medium 2-1 in the bundle of media 2 placed on the push plate unit 110.

[0082] Referring back to FIG. 1, the discrimination unit 200 can discriminate the medium 2-1.

[0121] The controller 700 can control the first lifting and lowering drive unit 140 and the second lifting and lowering drive unit 150 of the deposit and withdrawal unit 100 so that the first pickup roller 120 and the second pickup roller 130 operate together when the medium is transferred to the sheet transfer unit 600. When the first medium detection sensor 160 detects a bundle of media, the controller 700 can control the first lifting and lowering drive unit 140 to lower the first pickup roller 120 to contact the bundle of media, and when the second medium detection sensor 170 detects the bundle of media, the controller 700 can control the second lifting and lowering drive unit 150 to lower the second pickup roller 130 to contact the bundle of media.

[0122] The controller 700 can control the first lifting and lowering drive unit 140 and the second lifting and lowering drive unit 150 so that the first pickup roller 120 and the second pickup roller 130 respectively contact a front portion and a rear portion of a medium at two points when the medium is transferred to a position where the sheet transfer unit 600 is located. When the medium is transferred to the position where the sheet transfer unit 600 is located, the medium is transferred while the first pickup roller 120 and the second pickup roller 130 respectively contact the front and rear portions of the medium, so that intermittent twisting phenomenon of the medium can be prevented in advance.

[0123] Hereinafter, the operation and effects of the automated teller machine according to the second embodiment of the present disclosure will be described.

[0124] Referring to FIG. 20, when a bundle of media 2 is placed on the push plate unit 110 of the deposit and withdrawal unit 100 through the first entry and exit port 100a of the deposit and withdrawal unit 100, the first medium detection sensor 160 can detect the bundle of media 2 and transmit a detection signal for the bundle of media 2 to the controller 700.

[0125] Referring to FIG. 21, when the bundle of media 2 is detected by the first medium detection sensor 160, the controller 700 can control the link drive cylinder 143 of the first lifting and lowering drive unit 140 to lower the first pickup roller 120 to come into contact with the bundle of media 2. In addition, the controller 700 can control the roller rotation drive unit 630 to rotate the first pickup roller 120. The controller 700 can control the roller rotation drive motor 652 of the roller rotation drive unit 630 to rotate the first pickup roller 120. By controlling the roller rotation drive motor 652, the second pickup roller 130 and the feed roller 610 can also rotate together with the first pickup roller 120.

[0126] Referring to FIG. 22, due to the rotation of the first pickup roller 120, the bundle of media 2 placed on the push plate unit 110 can be transferred in the deposit direction by the first pickup roller 120 and the transfer assistance roller 180. When the bundle of media 2 is moved by a predetermined distance on the push plate unit 110 by the first pickup roller 120 and the transfer assistance roller 180, the second medium detection sensor 170 can detect the bundle of media 2 and transmit a detection signal for the bundle of media 2 to the controller 700. When the bundle of media 2 is detected by the first medium detection sensor 160, the controller 700 can control the lifting and lowering drive motor 155 of the second lifting and lowering drive unit 150 to lower the second pickup roller 130 to contact the bundle of media 2, and to raise the push plate unit 110. In this case, the height of the top sheet of the bundle of media 2 becomes aligned with the gap between the feed roller 610 and the gate roller 620 of the sheet transfer unit 600. In addition, the controller 700 can control the link drive cylinder 143 of the first lifting and lowering drive unit 140 to raise the first pickup roller 120 to be separated from the bundle of media 2.

[0127] Referring to FIG. 23, the controller 700 can control the link drive cylinder 143 of the first lifting and lowering drive unit 140 to lower and lift the first pickup roller 120 to repeatedly contact and separate from the bundle of media 2. The controller 700 can control the link drive cylinder 143 of the first lifting and lowering drive unit 140 to lower and lift the first pickup roller 120 repeatedly as many times as the number of media 2-1 of the bundle of media 2. For example, when the number of media 2-1 of the bundle of media 2 is 50, the controller 700 can repeat the descending and ascending operation of the first pickup roller 120 50 times. When the first pickup roller 120 and the second pickup roller 130 contact the front and rear portions of the medium at two points, and the medium is transferred to the sheet transfer unit 600, the single sheet of medium 2-1 can be fed between the feed roller 610 and the gate roller 620 of the sheet transfer unit 600. The medium 2-1 fed between the feed roller 610 and the gate roller 620 can be transferred to the discrimination unit 200 in the deposit direction by passing between the feed roller 610 and the gate roller 620. The transfer of the medium 2-1 from the bundle of media 2 to the discrimination unit 200 can be performed until all the media 2-1 of the bundle of media 2 are transferred to the discrimination unit 200 as the push plate unit 110 is gradually raised.

[0128] As described above, according to the present disclosure, it is possible to prevent intermittent twisting of the medium in advance by having the first pickup roller and the second pickup roller contact the front and rear portions of the medium at two points when the medium is transferred to the position where the sheet transfer unit is located. In addition, according to the present disclosure, there is provided a relatively simple configuration for separating bundled media in which multiple media such as banknotes are stacked and transferring them as individual sheets.

[0129] While the present disclosure has been shown and described with respect to the preferred embodiments, the scope of the present disclosure does not limited to the particular embodiments described, and those skilled in the art may variously change and substitute components within the scope of the present disclosure, which also belong to the scope of the present disclosure.
