In the first section 124, the lower conveyance path 124 may convey bills to and may receive bills from the safe 200 via interfaces 150 to 155 that provide bill conveyance paths. The interfaces 150 to 155 protrude downward from the lower surface of the handling unit 100. The interfaces 150 to 155 are inserted into respective openings (not shown) of the upper surface of the safe 200 and are directly or indirectly connected to cassettes and the like inside the safe 200. Referring to FIG. 1, the interfaces 151, 152, 154 and 155 may be directly connected to cassettes 210c, 210b, 210a and 230 inside the safe 200. The interfaces 150 and 153 may be connected to cassettes 220c, 220b and 220a inside the safe 200 via respective vertical conveyance units 240b and 240a.

One end of the second section 125 may be connected to the front end of the first section 124. A second switching gate 191 may be provided at the point where the first section 124 and the second section 125 are connected to each other. A bill conveyance path may be set by rotating the second switching gate 191 to switch the posture thereof. In the present embodiment, the second switching gate 191 is a three-way diverter. For example, in a first posture, the second switching gate 191 connects the first section 124 and the second section 125. In a second posture, the second switching gate 191 connects the second section 125 and the interface 155 which is connected to an abnormal bill storage cassette 230. In a third posture, the second switching gate 191 connects the first section 124 and the interface 155 which is connected to the abnormal bill storage cassette 230.

The other end, i.e., the front end of the second section 125 may be connected to the second vertical conveyance path 127 or the third section 126. To this end, a third switching gate 192 may be provided at the point where the second section 125, the second vertical conveyance path 127 and the third section 126 are converged. A bill conveyance path may be set by rotating the third switching gate 192 to switch the posture thereof. In the present embodiment, the third switching gate 192 is a three-way diverter. For example, in a first posture, the third switching gate 192 connects the second section 125 and the third section 126. In a second posture, the third switching gate 192 connects the second vertical conveyance path 127 and the third section 126. In a third posture, the third switching gate 192 connects the second vertical conveyance path 127 and the second section 125.

As described above, one end of the third section 126 may be connected to the second section 125 or the second vertical conveyance path 127. The other end of the third section 126 may be connected to a bill dispensing conveyance path 128 or a supplement/collection conveyance path 129. Although not shown in the drawings, a switching gate may be provided at the point where the third section 126, the bill dispensing conveyance path 128 and the supplement/collection conveyance path 129 are converged.

Both ends of the bill dispensing conveyance path 128 may be connected to the third section 126 of the lower conveyance path and the bill dispensing units 140 and 141. Both ends of the supplement/collection conveyance path 129 may respectively be connected to the third section 126 of the lower conveyance path and the removable cassette 300.

The handling unit 100 may include a discrimination device 130. For example, the discrimination device 130 may be provided on the upper conveyance path 122. The discrimination device 130 may discriminate the abnormality of bills, the type of bills and the like.

As described above, in the present embodiment, the bill dispensing units 140 and 141 may include a first bill dispensing port 140 and a second bill dispensing port 141. In the case of simultaneously using the first bill dispensing port 140 and the second bill dispensing port 141, bills having different characteristics may be discharged through the respective bill dispensing ports 140 and 141. For example, bills determined to be normal may be discharged through the first bill dispensing port 140. Bills determined to be abnormal may be discharged through the second bill dispensing port 141. As another example, among the abnormal bills to be dispensed, bills determined to be counterfeit bills may be discharged through the first bill dispensing port 140, and abnormal bills other than counterfeit bills may be discharged through the second bill dispensing port 141. Needless to say, counterfeit bills may be discharged through the second bill dispensing port 141.

As described above, the handling unit 100 may include not only the bill receiving unit 110 and the bill dispensing units 140 and 141 but also various other components such as the main conveyance unit 120 and the like. In order to perform the maintenance of internal components of the handling unit 100 and the removal of a jammed bill, the handling unit 100 may be designed to be relatively movable with respect to the safe 200.

As shown in the drawings, the safe 200 may be provided under the handling unit 100. The safe 200 may provide a space for storing bills and may protect bills from the access of an unauthorized person. A safe door 210 for selectively opening or closing the safe 200 may be provided on the front side of the safe 200.

A plurality of cassettes for storing different types of bills may be provided inside the safe 200. The cassettes may be provided in different sizes depending on the types of bills and the use frequency thereof. For example, in the case of the present embodiment, three large cassettes 210a, 210b and 210c for storing bills having a relatively high use frequency may be provided and three small cassettes 220a, 220b and 220c for storing bills having a relatively low use frequency may be provided under the large cassettes 210a, 210b and 210c. The bills stored in the large cassettes 210a, 210b and 210c are frequently used. Thus, the large cassettes 210a, 210b and 210c may be directly connected to the interfaces 151, 152 and 154 to shorten the conveyance time thereof. On the other hand, the bills stored in the small cassettes 220a, 220b and 220c are not frequently used. Thus, the small cassettes 220a, 220b and 220c are disposed under the large cassettes 210a, 210b and 210c and may be connected to the interfaces 150 and 153 via the vertical conveyance units 240a and 240b. This is a cassette arrangement structure provided in consideration of the limit when enlarging the safe 200 in the front-rear direction.

An abnormal bill storage cassette 230 for storing abnormal bills may be provided inside the safe 200. In the present embodiment, the abnormal bill storage cassette 230 is large in size and is positioned adjacent to the safe door 210.

The vertical conveyance units 240b and 240a may respectively connect the interfaces 150 and 153 and the small cassettes 220a, 220b and 220c disposed on the lower side. The vertical conveyance unit 240a may vertically extend between the cassettes spaced apart in the front-rear direction. In this sense, the vertical conveyance unit 240a may be referred to as a central conveyance part. In FIG. 1, the lower end of the central conveyance unit 240a may be connected to the two cassettes 220a and 220b. Thus, the central conveyance unit 240a may selectively supply bills to one of the cassettes 220a and 220b or may selectively receive bills from one of the cassettes 220a and 220b.

Although not shown in the drawings, the vertical conveyance units 240a and 240b may also be connected to the large cassettes 210a, 210b and 210c disposed on the upper side. For example, the vertical conveyance unit 240b at the rear side of the teller cash recycler 1 may be connected to not only the small cassettes 220c but also the large cassettes 210c.

As described above, the handling unit 100 may be moved relatively with respect to the safe 200 to protrude forward. Similarly, the cassettes existing inside the safe 200 may also be moved relatively with respect to safe 200 to protrude forward. For example, a cart (not shown) for accommodating a plurality of cassettes is provided inside the safe 200. When the safe door 210 is opened, the cart may be moved relatively with respect to the safe 200 to protrude forward. In this state, a user may perform a cassette replacement work, a bill collection work, a bill supplement work, a maintenance work, and the like.

If necessary, the removable cassette 300 may be mounted to the cassette mounting part 250 provided outside the safe door 210. When mounted to the cassette mounting part 250, the removable cassette 300 may be connected to the supplement/collection conveyance path 129 and, therefore, may be connected to the interior of the teller cash recycler 1.

Specifically, the removable cassette 300 mounted to the cassette mounting part 250 may be used for supplementing bills. For example, when there is a need to supplement specific bills to a specific cassette existing inside the safe 200, a user may put specific bills into the removable cassette 300 without operating the safe door 210 to open the safe 200 and may mount the removable cassette 300 to the cassette mounting part 250. The specific bills may be stored in the specific cassette inside the safe 200 via the supplement/collection conveyance path 129.

The removable cassette 300 may be used for collecting bills. For example, when there is a need to collect the bills stored in a specific cassette inside the safe 200, a user may mount the removable cassette 300 to the cassette mounting part 250 and then may cause the bills in the specific cassette to be conveyed to the removable cassette 300. The bills stored in the specific cassette may be put into the removable cassette 300 via the supplement/collection conveyance path 129. This enables the user to perform a bill collection work without operating the safe door 210 to open the safe 200.

If a certain bill is discriminated to be abnormal when dispending bills, such an abnormal bill may be conveyed to the removable cassette 300 rather than the bill dispensing units 140 and 141. This enables the user to easily check and collect an abnormal bill without operating the safe door 210 to open the safe 200 (This holds true in the case of receiving bills).

As described above, by providing the cassette mounting part 250 outside the safe door 210 so that, if necessary, the removable cassette 300 can be mounted to the cassette mounting part 250, a user can conveniently and easily perform various works without operating the safe door 210 to open the safe 200. In particular, it is not necessary to acquire an approval of an interested person of a bank in order to open the safe 200. This makes it possible to greatly improve the operation convenience of the teller cash recycler 1 and the user's accessibility.

Meanwhile, the teller cash recycler 1 according to the present embodiment may include a control unit (not shown). The control unit may refer to a component that governs all the bill conveyance and treatment operations performed in the teller cash recycler 1. For example, the control unit may control the operation of each of the conveyance units 120, 240a and 240b and may control the operation of each of the switching gates 190 to 192. Furthermore, the control unit may receive information on the characteristics of bills from the discrimination device 130. Based on the information, the control unit may control the operations of the internal components of the teller cash recycler 1 in a predetermined manner. In addition, the control unit may control the operations of the internal components of the teller cash recycler 1 in a preset manner to execute a command received from a user. The internal components of the teller cash recycler 1 may include the removable cassette 300. Thus, the control unit may govern the conveyance and treatment of bills related to the removable cassette 300.

FIG. 2 is a view showing an example of a state in which bills are received by the teller cash recycler 1 shown in FIG. 1. A bill receiving route is indicated by a thick solid line. A bill rejecting route is indicated by a dotted line.

Bills received through the bill receiving unit 110 may be conveyed into the teller cash recycler 1 along the upper conveyance path 122. At this time, the first switching gate 190 may have the first posture to connect the bill receiving unit 110 and the upper conveyance path 122. The bills may pass through the discrimination device 130 existing on the upper conveyance path 122. The discrimination device 130 may discriminate the abnormality of bills and the type of bills. If the bills are discriminated to be normal, the bills may be stored in the cassette conforming to the type of the bills. For example, as shown in FIG. 2, the bills may be stored in the small cassette 220c on the lower side after passing through the first vertical conveyance path 123 and the vertical conveyance part 240b. Alternatively, the bills may be stored on the small cassette 220b in the lower side after passing through the first vertical conveyance path 123, the lower conveyance path 124 and the vertical conveyance part 240a. Alternatively, the bills may be stored in the large cassette 210a on the upper side of the safe 200 after passing through the first vertical conveyance path 123 and the lower conveyance path 124. On the other hand, if the bills are discriminated to be abnormal, as indicated by the dotted line, the bills may be returned to a user through the first bill dispensing port 140 after passing through the first vertical conveyance path 123, the lower conveyance paths 124, 125 and 126 and the bill dispensing conveyance path 128. At this time, the second switching gate 191 may have the first posture to connect the first section 124 and the second section 125, and the third switching gate 192 may have the first posture to connect the second section 125 and the third section 126.

FIG. 3 is a view showing an example of a state in which bills are dispensed from the teller cash recycler 1 shown in FIG. 1. A bill dispensing route is indicated by a thick solid line. A bill rejecting route is indicated by a dotted line.

For example, the bills stored in the small cassette 220b on the lower side may be conveyed along the vertical conveyance part 240a, the lower conveyance path 124, the first vertical conveyance path 123 and the upper conveyance path 122. If the bills passing through the discrimination device 130 are discriminated to be normal, the bills may be discharged to the first bill dispensing port 140 through the second vertical conveyance path 127, the lower conveyance path 126 and the bill dispensing conveyance path 128. Furthermore, the bills stored in the small cassette 220c on the lower side may be conveyed along the vertical conveyance part 240b, the first vertical conveyance path 123 and the upper conveyance path 122. If the bills passing through the discrimination device 130 are discriminated to be normal, the bills may be discharged to the first bill dispensing port 140 through the second vertical conveyance path 127, the lower conveyance path 126 and the bill dispensing conveyance path 128. At this time, the first switching gate 190 may have the second posture to connect the upper conveyance path 122 and the second vertical conveyance path 127, and the third switching gate 192 may have the second posture to connect the second vertical conveyance path 127 and the third section 126. If the bills are discriminated to be abnormal, the bills may be conveyed along the second vertical conveyance path 127 and may be conveyed to the second section 125 rather than the third section 126. Thereafter, the bills may be stored in the abnormal bill storage cassette 230. At this time, the third switching gate 192 may have the third posture to connect the second vertical conveyance path 127 and the second section 125, and the second switching gate 191 may have the second posture to connect the second section 125 and the interface 155 connected to the abnormal bill storage cassette 230.

A user may load one or more types of bills in the removable cassette 300 and may mount the removable cassette 300 to the cassette mounting part 250. If a supplementing work is started, the bills may be conveyed from the removable cassette 300 along the supplement/collection conveyance path 129, the third section 126, the second vertical conveyance path 127 and the upper conveyance path 122. At this time, the third switching gate 192 may have the second posture to connect the second vertical conveyance path 127 and the third section 126, and the first switching gate 190 may have the second posture to connect the upper conveyance path 122 and the second vertical conveyance path 127. If the bills passing through the discrimination device 130 are determined to be normal, the bills may be stored in the cassette existing inside the safe 200 (e.g., the small cassettes 220b and 220c shown in FIG. 4). If the bills are discriminated to be abnormal, the bills may be discharged to the first bill dispensing port 140 through the first vertical conveyance path 123, the lower conveyance paths 124, 125 and 126 and the bill dispensing conveyance path 128. At this time, the second switching gate 191 may have the first posture to connect the first section 124 and the second section 125, and the third switching gate 192 may have the first posture to connect the second section 125 and the third section 126. In addition, if the bills are discriminated to be counterfeit bills, the counterfeit bills may be discharged to the second bill dispensing port 141. In this case, the abnormal bills other than the counterfeit bills may be discharged to the first bill dispensing port 140.

In addition, when the bills are discriminated to be abnormal, the operation of discharging the bills stored in the removable cassette 300 may be interrupted. After completing the treatment (e.g., dispensing) of the bills discriminated to be abnormal, the operation of discharging the bills stored in the removable cassette 300 may be resumed. Otherwise, the bills discriminated to be abnormal and the bills newly discharged from the removable cassette 300 may collide with each other in the third section 126 of the lower conveyance paths.

FIG. 5 is a view showing an example of a state in which bills are collected from the teller cash recycler 1 shown in FIG. 1. A bill collecting route is indicated by a thick solid line. A bill rejecting route is indicated by a dotted line.

A user may mount the removable cassette 300 to the cassette mounting part 250. If a collection work is started, the bills stored in the small cassette 220b on the lower side may be conveyed along the vertical conveyance unit 240a, the lower conveyance path 124, the first vertical conveyance path 123 and the upper conveyance path 122. The bills stored in the small cassette 220c on the lower side may be conveyed along the vertical conveyance unit 240b, the first vertical conveyance path 123 and the upper conveyance path 122. If the bills passing through the discrimination device 130 on the upper conveyance path 122 are discriminated to be normal, the bills may be collected to the removable cassette 300 through the second vertical conveyance path 127, the third section 126 and the supplement/collection conveyance path 129. At this time, the first switching gate 190 may have the second posture to connect the upper conveyance path 122 and the second vertical conveyance path 127. The third switching gate 192 may have the second posture to connect the second vertical conveyance path 127 and the third section 126.
