Next, a waste cassette 130 is installed at the rear end of the case 100 to determine whether banknotes are stored. The bill cassette 130 is detachably installed in the case 100.

In addition, adjacent to the bill cassette 130, a bill separator 140 is provided for separating the bills one by one and forcibly transferring them. The bill separating unit 140 is driven by receiving the power of the drive motor 110 selectively. Herein, the configuration for selectively receiving the power of the driving motor 110 is not the gist of the present invention, and thus detailed description thereof will be omitted.

The bill separation unit 140 is provided with a pickup roller 142 for taking out the bills of the bill cassette 130 one by one. In the pickup roller 142, a rubber section is formed in a predetermined section to take out a bill from the bill cassette 130 using friction with the bill, and the remaining section is formed of a smooth surface. A guide 143 for guiding the bills picked up by the pickup roller 142 extends from the pickup roller 142 toward the transfer roller 144 to be described below.

Then, the transfer roller 144 for transferring the bill picked up by the pickup roller 142 is selectively driven by the clutch drive gear 128 is rotated by the driving force of the drive motor 110. A rubber section for conveying the rollers by friction with banknotes is also formed in the feed roller 144, and the remaining sections are formed in a smooth surface.

Separation roller 146 is installed in close contact with the feed roller 144. The separation roller 146 is rotated in the same direction as the transfer roller 144 to separate the overlapped conveyed from the bill conveyed by the feed roller 144.

A driving pulley 145 is coaxially installed on the feed roller 144 for rotation in the same direction of the feed roller 144 and the separation roller 146, and the driven pulley 147 is also coaxial to the separation roller 146. ) Is installed, and the pulleys 145 and 147 are connected to the belt 145v.

The transfer guide 149 having a predetermined curvature guides the banknotes passed between the transfer roller 144 and the separation roller 146 to the banknote transfer path described below.

A plurality of pairs of feed rollers are installed to transfer the bills guided by the feed guide 149.

First, the first feed roller pairs 150 and 150 'are installed side by side so as to be driven by the third driving gear 126. In this case, the first feed roller 150 is driven by the third drive gear 126 and the first feed roller 150 'corresponding to the first feed roller 150 is rotated by friction with the first feed roller 150.

The second feed roller pairs 152 and 152 'are arranged side by side on the upper portions of the first feed roller pairs 150 and 150' to be driven by the second driving gear 122. In addition, the third feed roller pairs 154 and 154 'are installed side by side so as to be driven by the first driving gear 121. Here too, power transfer is achieved by friction between the feed roller pairs 152, 152 ', 154, 154'.

The feed roller pairs 150, 150 ', 152, 152', 154, 154 'are installed to form a straight path. In this case, along the straight paths formed by the transfer roller pairs 150 and 150 ', 152 and 152' and 154 and 154 ', the transfer guide plates 155 are installed at both sides to guide the transfer of bills.

Here, the rotation detecting sensor 151 for detecting the rotation state of the drive motor 110 is installed adjacent to the first feed roller 150. The rotation sensor 151 detects the rotation of the rotation wheel 150w coaxially installed in the first transfer roller 150 to detect the rotation state of the drive motor 110.

As described above, a configuration for transferring the banknotes transferred along the straight path to the customer payout port 170 or the collection box 180 is transmitted. The driving force for switching the conveying path of the banknote conveyed along the straight path is provided by the solenoid 160. The diverter 162 is connected to the drive plate 161 of the solenoid 160. The diverter 162 has a front end portion installed at the end of the straight path to switch the path in which the bill is moved by the driving of the solenoid 160. To this end, first and second guide surfaces 162a and 162b are formed at both ends of the diverter 162 in both directions. Reference numeral 163 denotes a detection sensor for detecting an initial operation of the solenoid 160.

Meanwhile, the discharge roller 164 and the recovery roller (164) and the recovery roller (164) correspond to the third pair of transport rollers 154 and 154 'for transporting the banknotes whose transport path is determined by the diverter 162 after being transported along the straight path. 166 is installed. The release roller 164 cooperates with the third transfer roller 154 to deliver the bill to the customer payout 170. The collection roller 166 cooperates with the third transfer roller 154 ′ to transfer the bill to the collection box 180. Here, the discharge roller 164 and the recovery roller 166 are driven by friction with the third pair of transport rollers 154 and 154 ', respectively.

Next, the ejection sensor for detecting the bill is discharged from the customer payout 170 to count the number of bills released, and provides a signal for driving the bill separating unit 140 for the next bill release operation ( 172 is installed at the customer payout 170 side.

The recovery path is provided with a recovery sensor 182 that detects the collection of the bill and provides a signal for driving the bill separation unit 140 for the next bill release operation.

Next, in the straight path, the thickness of the transfer sensor 180 which detects the thickness of the banknotes to be transferred and the preparation sensor 190 for providing various signals required for driving the banknotes is transferred to the collection box 180. The detection sensor 192 is provided. The preparation sensor 190 detects that the bill is transferred by the first feed roller pairs (150, 150 ') to prepare for the operation of the thickness detection sensor 192, and accordingly driving and driving the solenoid 160 It provides a signal for driving stop of the banknote separator 140.

It will be described below that the embodiment of the present invention having the configuration as described above is operated.

When the discharge command of the banknote is given, the drive motor 110 is rotated to provide power. Then, the pick-up roller 142 of the bill separating unit 140 received the driving force of the driving motor 110 is rotated to pick up the bills inside the bill box 130 one by one. And, the pick-up roller 142 The bill picked up by) is guided along the guide 143 and transferred to the transfer roller 144.

The bills are transported by the rotation of the transport roller 144, and the bills overlapped and transported by the separation roller 146 rotating in the same direction as the transport roller 144 are separated. At this time, the separated bill is guided to the guide 143 by a mechanism (not shown). Since the mechanism for guiding the separated banknote in the guide 143 is already known, its detailed description is omitted. In this way, the paper money remaining in the guide 143 is transported and discharged by the feed roller 144 at the next bill release command.

Meanwhile, the banknotes normally transferred are guided by the transfer guide 149 through the transfer roller 144 and the separation roller 146 by the continuous rotation of the transfer roller 144, and the front end portion thereof is guided by the first transfer roller pair. Is passed between 150 and 150 '. And bills are started to be transferred along the straight path by the first feed roller pair 150, 150 '.

At this time. When the tip portion of the bill passing through the first feed roller pair 150, 150 ′ is detected by the preparation sensor 190, the preparation sensor 190 issues an operation preparation command of the thickness detection sensor 192, and the bill The power transmitted to the separation unit 140 is blocked. Therefore, the banknote separation unit 140 is no longer operated so that no further banknotes are ejected from the banknote cassette 130.

Then, when the bill is continuously transferred, the thickness detection sensor 192 detects the thickness of the bill and detects that two sheets are overlapped and transferred. That is, by detecting the thickness difference between the case where one sheet is transferred and the two sheets are overlapped, only one sheet is normally transferred.

Next, after passing through the thickness detecting sensor 192, the banknotes are transferred by the second feed roller pairs 152 and 152 'and the third feed roller pairs 154 and 154'. And when the bill is transferred by the transfer roller pair as described above, the transfer guide plate 155 is a linear movement of the bill.

In addition, when it is determined that one bill is conveyed by the thickness sensor 192, the bill conveyed by the third feed roller pairs 154 and 154 'is left in an initial state without operating the solenoid 160. The first guide surface 162a of the diverter 162 is guided to the customer payout 170 by the discharge roller 164 and the third transfer roller 154.

At this time, the eject sensor 172 detects the release of the bill, counts the number of bills released, and provides a signal for detecting the completion of the bill to allow the bill separator 140 to be operated again.

On the other hand, when it is determined in the thickness sensor 192 that the multiple bills are overlapped and transmitted or is determined to be a bad bill, the solenoid 160 is operated by the detection signal so that the diverter 162 shows FIG. 2. The paper money is guided to the second guide surface 162b by being rotated in the clockwise direction, and the paper money is collected by the third conveying roller 154 'and the collecting roller 166 into the collecting box 180.

At this time, the collection sensor 182 detects the number of bills to provide a signal to the bill separating unit 140 to perform the following operation.

After the bills are released or recovered in this manner, the above operation is repeated, and the bills are ejected as many times as desired.

On the other hand, Figure 4 shows another embodiment of the present invention. The configuration of this embodiment is the same as the above embodiment, but only the customer payout 170 is installed at the lower end of the case 100. This is a mechanism installed inside the case 100 to turn over. Therefore, it has the same configuration and operation as the embodiment of FIG. 2, but only a straight line transfer path of the banknote is made from top to bottom. Therefore, the function and operation description of each part is not much.

It is possible to discharge the bottom of the banknote by this configuration, and the transfer of the banknote is possible because the transfer path is a straight path and a plurality of rollers are used. Particularly, the banknote separated from the banknote separator is forced by the feed roller 144. It is possible to be transferred to the straight path as possible.

Although the present invention having the configuration as described above has been described with an automatic banknote dispenser as an example, the present invention is not limited thereto and may be applied to a ticket vending machine for the release of various tickets.

Banknote dispenser according to the present invention as described in detail above to integrate the components and to be driven by a single drive motor it is possible to reduce the size of the banknote dispenser as a whole.

And the whole structure is installed inside one case, and the path for the transfer of banknotes is straightened as a whole, and rollers are used for the transfer. When the mechanism is installed upside down, the release position of banknotes can be freely selected. It can meet the needs.

And the path for the transfer of bills is straightened, so that the occurrence of jams during bill transfer is greatly reduced, and since only one driving motor is used as a whole, the structure is simplified and thus manufacturing cost can be lowered.
