Therefore, the media carrier 130 can be transferred to each withdrawal unit, thereby supplying the paper medium P held in the media carrier 130 to the withdrawal unit.

Meanwhile, the reject medium transfer unit 160 transfers the paper medium P whose abnormality is detected when the paper medium P is transferred through the medium transfer unit 120 to the recovery medium storage unit 170 to be described later. Do it. As shown in FIG. 1, the reject medium transfer unit 160 may include a plurality of rollers and a belt to transfer the rejected paper medium P to the recovery medium storage unit 170.

Meanwhile, the recovery medium storage unit 170 of the present embodiment is rejected while being transported along the paper carriers P or the media transfer unit 120 which have been withdrawn from the withdrawal unit, but the reject medium transfer unit 160. It serves to recover the paper medium (P) to be transported through.

In other words, the recovery medium storage unit 170 is unreceived and retracted by the customer, the paper medium (P), and the abnormally discharged and rejected paper from the media storage cassette 110 to the media transfer unit 120 It is a cassette type storage unit for storing the media (P).

Meanwhile, the media storage cassette 110 according to the present embodiment is a portion for storing the paper medium P, and as shown in detail in FIGS. 2 and 3, a storage case in which a plurality of paper media P is stored. 111 and a pressurizing portion 115 which is mounted to be movable inside the storage case 111 to press the plurality of paper media P in the stacking direction from which the paper media P is discharged, and a pressurizing portion. A signal transmitting and receiving unit 180 provided at 115 to transmit and receive a predetermined signal, and spaced apart from the bottom of the storage case 111 along the moving direction of the pressing unit 115, and transmitted from the signal transmitting and receiving unit 180. Reflected by a plurality of unit reflection members (185a, 185b, 185c, 185d) to detect the remaining amount of the paper medium (P) stored in the storage case 111 by transmitting the reflected to the signal transmission and reception unit 180 Part 185 is included.

In addition to the above configuration, the medium storage cassette 110 according to the present embodiment supports the front end portion of the paper medium P which is attached to the front end region in the storage case 111 and pressed by the pressing portion 115. The support part 118 may further include a guide part 117 that guides the movement path of the paper medium P.

Referring to these configurations, first, the storage case 111 plays a role of storing the paper medium P as described above. The paper medium P may be cash such as bills, checks, gift certificates and tickets.

This storage case 111 is shielded by the cover 112. However, the storage case 111 and the cover 112 has a locking structure so that only an authorized operator can open or shield the cover 112 from the storage case 111.

Meanwhile, as shown in FIGS. 2 and 3, the pressing unit 115 is mounted inside the storage case 111 to be movable in the direction in which the paper medium P is stacked. The pressing unit 115 has its own power source (not shown) and may linearly move from the inside of the front case 111 to the front or the rear by a driving force generated from the power source.

The front plate of the pressing unit 115 is provided with a flat plate-shaped plate 116, the plate 116 is formed to have a wide left and right width to press the paper medium (P) as a whole.

On the other hand, the signal transmitting and receiving unit 180 is disposed to be exposed to the lower surface of the pressing unit 115. The signal transceiver 180 of the present embodiment may be provided as an optical sensor 180 that transmits and receives light. The optical sensor 180 continuously emits light when the pressing unit 115 supports and presses the paper medium P, thereby allowing the remaining amount of the paper medium P to be detected. This will be described in detail when the reflector 185 is described.

However, in the present embodiment, the optical sensor 180 for transmitting and receiving light is applied as the signal transmitting and receiving unit 180, but is not limited thereto, and the signal transmitting and receiving unit 180 is another sensing sensor such as an infrared sensor. Naturally, it can be prepared.

2 and 3, the plurality of unit reflecting members 185a are spaced at equal intervals along the moving path of the signal transmitting and receiving unit 180 on the bottom surface of the storage case 111 as illustrated in FIGS. 2 and 3. 185b, 185c, and 185d).

That is, the reflection unit 185 is not provided continuously, but is provided discontinuously. Therefore, when the signal transmission and reception unit 180 passes through the upper portion of the reflector 185, the signal is transmitted and received when passing through an area including the unit reflection members 185a, 185b, 185c, and 185d. Signals are not transmitted or received when passing between the regions where 185a, 185b, 185c, and 185d are not disposed, that is, between unit reflective members 185a, 185b, 185c, and 185d.

Accordingly, the number of times that the signal transmitting and receiving unit 180 passes through an area in which the plurality of unit reflection members 185a, 185b, 185c, and 185d are formed, and an area between the plurality of unit reflection members 185a, 185b, 185c, and 185d. The remaining amount of the paper medium P stored in the storage case 111 may be detected step by step based on the number of times passed. Here, as the number of areas where the unit reflecting members 185a, 185b, 185c, and 185d are formed and the number of areas where the unit reflecting members 185a, 185b, 185c, and 185d are not formed increase, the remaining amount of the paper medium P increases. Decreases, so appropriate action can be taken.

For example, with the movement of the pressing unit 115, the signal transmitting and receiving unit 180 is located at the rear end of the unit reflector members 185a, 185b, 185c, and 185d and the unit reflection member 185a located in front of it. In the case of passing through the member 185b, the signal transceiving unit passes through the area where the plurality of unit reflection members 185a, 185b, 185c, and 185d are formed two times, and the unit reflection members 185a, 185b, 185c, and 185d. The number of passes through an area where) is not arranged is one.

Therefore, the remaining amount of the paper medium P stored in the storage case 111 can be accurately detected based on the detection result, and the filling operation of the paper medium P can be executed at an appropriate time. In this case, the number of times in which the plurality of unit reflection members 185a, 185b, 185c, and 185d is formed, and the region in which the plurality of unit reflection members 185a, 185b, 185c, and 185d are not formed, pass through the signal transceiver 180. The remaining amount of the paper medium P corresponding to the number of times is a preset value on a control unit (not shown) for controlling the operation of the media storage cassette 110, and based on this value, the remaining amount of the paper medium P is determined. It can detect in stages and precisely.

As such, when the signal transceiving unit 180 and the plurality of unit reflecting members 185a, 185b, 185c, and 185d of the reflecting unit 185 interact with each other in a stepwise manner, and information about this is displayed on the outside, the operator may press a paper. The remaining amount of the medium P can be estimated more accurately, and thus an operation such as refilling the paper medium P can be performed.

Each unit reflecting member 185a, 185b, 185c, 185d of the reflecting unit 185 is provided with a reflecting plate having a predetermined reflectance but having the same reflectance. Therefore, the light transmitted from the signal transceiver 180 provided by the optical sensor 180 may be reflected and transmitted back to the signal transceiver 180.

In addition, the plurality of unit reflection members 185a, 185b, 185c, and 185d may be formed in the reflector accommodating space 186 recessed inward from the bottom of the storage case 111, as illustrated in FIGS. 4 and 5. Spaced at equal intervals. Accordingly, when the paper medium P is transported along the bottom surface of the storage case 111, interference between the paper medium P and the reflector 185 may be prevented from occurring. The transfer operation and the interaction between the signal transmission and reception unit 180 and the reflection unit 185 may be smoothly performed.

Meanwhile, as described above, in order to externally display the stepwise interaction between the signal transceiving unit 180 and the plurality of unit reflecting members 185a, 185b, 185c, and 185d of the reflecting unit 185, a medium storage cassette. A display unit (not shown) may be provided at an outer region of the 110.

Although not shown, the display unit may be provided on a monitor (not shown) of the financial automation device 100 so as to be recognized by an external user.

In addition, the support part 118 serves to support the paper medium P, which is in contact with the paper medium P at the frontmost position of the plurality of paper media P stacked in a plurality, and is pressed by the pressing unit 115 as a whole. Do it. The support part 118 may be equipped with a slip member (not shown) to prevent the paper medium (P) from slipping, so that the paper medium (P) at the leading end does not slip to the media feeder (120). It can be transferred smoothly.

Meanwhile, as illustrated in FIGS. 2 and 3, the guide part 117 is detachably coupled to the bottom surfaces of both sides of the storage case 111. Therefore, the position of the guide part 117 can be adjusted to the left and right directions according to the size of the paper medium P. As a result, the paper medium P moves forward by the pressing unit 115. Ensures smooth transfer without disturbance.

Hereinafter, a method of detecting the remaining amount of the paper medium P applied to the media storage cassette 110 having such a configuration will be described with reference to FIGS. 4 to 6. 6 is a flowchart of a method of detecting a remaining amount of a paper medium applied to a cassette for storing media according to an embodiment of the present invention.

First, after the cover 112 is opened from the storage case 111, a plurality of paper media P are stored between the support part 118 and the pressing part 115 (S100). In this case, the pressing unit 115 may be moved to be positioned at the rearmost side of the storage case 111, and thus a large amount of paper medium P may be filled in the storage case 111.

Thereafter, after the storage case 111 is shielded by the cover 112, the cassette 110 for storing media is inserted into the cassette storage space 110S of the financial automation device 100. Then, the transfer paths of the storage case 111 and the medium transfer unit 120 are connected so that the paper medium P of the storage case 111 may be transferred to the medium transfer unit 120.

Then, when the paper medium (P) is discharged from the storage case 111 by withdrawal, etc., the pressing unit 115 moves in the discharge direction of the paper medium (P) and presses the paper medium (P) to the front side (S200). ).

At this time, the signal transmitting and receiving unit 180 mounted on the pressing unit 115 is continuously driven to detect the remaining amount of the paper medium (P) stored in the storage case 111 step by step (S300).

In more detail, when the signal transceiver 180 is shown in FIG. 4, when the reflector 185 is located in an unformed region, the signal is not received, and thus the signal transceiver 180 is reflected from the signal transceiver 180. The interaction of the part 185 is not made. In this case, since the remaining amount of the paper medium P stored in the storage case 111 is larger than the preset residual amount reference value, no further action is taken in this case.

However, when the signal transceiver 180 is located on the reflector 185, as shown in FIG. 5, an interaction between the signal transceiver 180 and the reflector 185 may occur. Information may be displayed on the display unit (S400). For example, when the signal transceiver 180 is located on the unit reflective member 185b located second from the rear of the plurality of unit reflective members 185a, 185b, 185c, and 185d, the signal transceiver 180 may be Areas where the unit reflection members 185a, 185b, 185c, and 185d are formed twice, and where the unit reflection members 185a, 185b, 185c, and 185d are not formed (unit reflection members 185a, 185b, 185c, and 185d). 1), and a signal indicating a residual amount corresponding to the same may be displayed on the display unit.

In this case, since the remaining amount of the paper medium P stored in the storage case 111 is less than the preset residual amount reference value, the operator who handles the medium storage cassette 110 takes measures such as refilling the paper medium P. FIG. Can be (S500).

As described above, according to the present exemplary embodiment, the remaining amount of the paper medium P stored in the storage case 111 can be detected, but the remaining amount of the paper medium P can be detected step by step, so that the paper medium P can be detected. The paper medium P can be refilled before it is emptied, which has the advantage of further improving the reliability of the withdrawal operation for the customer.

On the other hand, with reference to the accompanying drawings will be described a media storage cassette according to another embodiment of the present invention. However, the same descriptions as those described in the media storage cassette according to the exemplary embodiment will be omitted.

As shown in these figures, the reflecting portion 285 according to the present embodiment includes a plurality of unit reflecting members 285a, 285b, 285c, and 285d, and each unit reflecting member 285a, 285b, 285c, 285d) has different reflectances.

Accordingly, the signal transceiver 280 may detect the remaining amount of the paper medium P by changing the reflectance while passing through the plurality of unit reflection members 285a, 285b, 285c, and 285d. Therefore, the time at which the signal transmitted from the signal transceiver 280 reaches the signal transceiver 280 again varies due to the difference in reflectance between the unit reflection members 285a, 285b, 285c, and 285d. The remaining amount of the paper medium P can be detected step by step.

In addition, the display unit displays the result of mutual transmission and reception between the signal transmission and reception unit 280 and the reflection unit 285 so that an operator or the like operating the cassette for storing the medium may gradually determine the remaining amount of the paper medium P stored in the cassette for storing the medium. Make it understandable.

As described above, according to another embodiment of the present invention, the signal transmitting and receiving unit 280 interacts with the plurality of unit reflecting members 285a, 285b, 285c, and 285d having different reflectances in a stepwise manner, The remaining amount can be detected step by step, and thus there is an advantage that the paper medium P can be refilled before the paper medium P is empty.

In the above-described embodiments, the role of transmitting a signal and the role of receiving a signal are described above by an integrated signal transmitting / receiving unit, but the present invention is not limited thereto, and the transmitting unit transmitting the signal and the receiving unit receiving the signal are separate. Naturally, the signal transmission and reception unit may be provided on the pressing unit.

In addition, in the above-described embodiment, the unit reflecting members having the same reflectance are arranged at equal intervals, and in another embodiment, the unit reflecting members having the different reflectances are disposed at the same distance.
