Hereinafter, the internal configuration of the media storage box 40 will be described in detail.

FIG. 3 is a view schematically showing a media storage box according to an embodiment of the present invention, and FIG. 4 is a view showing a state in which a support plate of the media storage box of FIG.

3 and 4, the media storage 40 according to an embodiment of the present invention includes a frame 41, an integrated space 42 in which the medium M is accommodated, And may include a media entrance 43.

The media access port 43 may be formed at the upper end of the frame 41. The medium M may be introduced into the accumulating space 42 formed inside the frame 41 through the medium entry / exit port 43. The medium M accumulated in the accumulation space 42 can be drawn out to the outside through the medium access port 43.

The media storage box 40 may further include a feed roller 120 for the introduction or withdrawal of the medium M. The feed roller 120 may be rotatably connected to the frame 41.

The media storage box 40 may further include a support plate 151 provided in the accumulation space 42. The medium M accommodated in the accumulation space 42 may be seated on the support plate 151.

The support plate 151 can be moved up and down by a driving unit. Specifically, the support plate 151 may be moved so as to be disposed close to the media access port 43 when preparing the media M through the media access port 43.

The position of the support plate 151 can be adjusted according to the amount of the medium M accumulated when the medium M is introduced through the media entrance 43. Specifically, as the amount of the medium M accumulated on the support plate 151 increases, the support plate 151 descends to secure the capacity of the accumulation space 42.

The media storage box 40 is provided with a number measuring sensor (not shown) for measuring the number of media M to be introduced into the accumulating space 42, (Not shown) that can be used to control the temperature of the liquid.

The integration confirmation sensor is provided at a predetermined height in the integration space 42. When the integration confirmation sensor is obscured by the medium M, the integration confirmation sensor recognizes that the medium is integrated in the support plate 151 . The control unit may lower the support plate 151 so that the medium M accumulated on the support plate 151 does not cover the integration confirmation sensor. Accordingly, even if the medium M is continuously drawn, the support plate 151 is lowered to correspond thereto, so that the medium M accumulated on the support plate 151 is maintained not to exceed the height of the integration confirmation sensor .

When the medium M is drawn into the accumulation space 42, the accumulation of the medium M can be recognized by the accumulation confirmation sensor at the same time that the introduction of the medium M is detected by the counting sensor, The support plate 151 can be controlled to be lowered.

The support plate 151 can be moved in units of one step. The support plate 151 can be controlled to move 0.05 mm per step. Therefore, when the thickness of one sheet of the medium M is 0.2 mm, the support plate 151 can be controlled to move by four steps and move by the thickness of the medium M. The number of steps in which the support plate 151 is moved by the introduction of the medium M can be stored in a memory or the like.

Meanwhile, the amount of movement of the support plate 151 can be predicted according to the amount of the medium M measured by the counting sensor.

For example, if the thickness of the introduced medium M is about 0.15 mm, it can be predicted that the support plate 151 moves by three steps per medium M so as to move by the thickness of the medium M. In addition, when the number of the introduced media M is 100, the total thickness of the introduced media M is 15 mm, so that the support plate 151 can be predicted to move by 300 steps.

Meanwhile, the number-of-sheets measuring sensor can measure the length of the introduced medium M to correct the predicted movement amount of the support plate 151. For example, when the length of the introduced medium M is longer than 150% of the set medium M, the movement amount of the support plate 151 can be predicted to be twice the set movement amount.

Since the actual movement amount of the support plate 151 is determined by whether or not the medium M is detected by the integration confirmation sensor, the actual movement amount of the support plate 151 and the actual movement amount of the support plate 151 predicted by the number- A deviation may occur in the movement amount. That is, when the pile of the medium M accumulated on the support plate 151 is inflated, the support plate 151 may descend beyond the movement amount predicted by the number of the introduced media M.

Therefore, the control unit can measure the degree of swelling of the dummy of the medium M by comparing the movement amount of the support plate 151 predicted according to the number of the introduced media M with the actual movement amount of the support plate 151.

The media storage box 40 may further include a pick-up roller 140 for picking up and discharging the medium M accommodated in the accumulation space 42. The pickup roller 140 rotates and rubs against the medium M so that the medium M can be drawn out after the support plate 151 rises to the pickup roller 140 side when the medium M is taken out.

Also, even when the medium M is not pulled out, when the medium M is accumulated by a predetermined amount or more, the support plate 151 can be raised and pressurized the medium M. Thus, the pile of swollen medium (M) can be compressed by the air layer formed between the plurality of media (M).

Hereinafter, a control method of the medium storage box 40 for media (M) compression will be described with reference to flowcharts.

5 is a flowchart showing a control method of a media storage box for compressing a medium integrated therein.

First, when the medium M is introduced through the media entrance 43, the number of media M drawn through the sensor provided in the media storage 40 and the amount of movement of the support plate 151 are measured (S2).

As the height of the medium M accumulated on the support plate 151 increases, the support plate 151 moves downward as the height of the medium M accumulates on the medium M, do. The control unit for controlling the media storage box 40 may determine whether the media M is compressed and the compression time of the media M based on the number of the introduced media M and the movement amount of the support plate 151 (S3).

More specifically, when the amount of movement of the support plate 151 is larger than the amount of movement of the support plate 151 predicted by the number of the introduced media M, the control unit forms an air layer between the plurality of media M It is judged to be swollen. If it is determined that the stack of media M formed by a plurality of media M is swollen, the control unit may instruct the support plate 151 to compress the media M.

The movement amount of the support plate 151 predicted by the number of the introduced media M can be stored in advance in the memory.

The compression time of the medium M can be determined based on the degree of swelling of the medium M. For example, it is possible to control the compression time to increase as the size of the pile of the medium (M) increases. Therefore, the compression time can be longer as the deviation between the movement amount of the support plate 151 and the movement amount of the actual support plate 151 predicted by the number of the introduced media M becomes larger.

The degree to which the pile of the medium M is swollen can be determined by using the difference between the movement amount of the support plate 151 predicted by the number of the introduced media M and the actual movement amount of the support plate 151 . That is, the control unit may increase the compression time of the medium M by determining that the difference between the predicted movement amount of the support plate 151 and the actual movement amount is larger, and the degree of swelling of the medium M is greater.

Specifically, when the actual movement amount of the support plate 151 exceeds the predicted movement amount, the compression time of the medium M can be increased by the time multiplied by the number of steps in which the actual movement amount exceeds the predetermined amount.

For example, the compression time of the medium M may be increased by one second every time the actual movement amount of the support plate 151 exceeds one step than the predicted movement amount. In this case, when the actual movement amount of the support plate 151 exceeds 10 steps than the predicted movement amount, the compression time of the medium M can be increased by 10 seconds. The control unit controls the support plate 151 to move to compress the medium M (S4). When the compression time has elapsed, the controller moves the support plate 151 to control the compression of the medium M to be released (S5).

On the other hand, even when the medium M is being compressed, when the medium M pull-in or pull-out command is input, it is possible to release the compression and control the medium M to be pulled in or pulled out. Further, even when the power of the financial instrument 1 is turned off, the compression by the support plate 151 can be controlled to be released.

Hereinafter, a control method in the case where a plurality of media storage boxes 40 for storing only the same kind of medium M will be described in the financial instrument 1 of the present invention. In the case of the media storage box having the same type of the medium M to be stored in the plurality of media storage boxes 40, it is referred to as the same kind of media storage box. Here, the type of the medium M means the denomination of the banknote when the medium M is a banknote, and the same kind may mean that the denomination of the banknote is the same.

When the medium M is drawn through the media input / output unit 13, the controller selects any of the plurality of media storage boxes 40 to which the medium M is to be loaded.

At this time, the controller selects a medium storage box 40 not being compressed by the support plate 151 among the plurality of media storage boxes 40, and draws the medium M. In other words, among the plurality of media storage boxes 40 of the same type, the media storage box 40 being compressed may stop the introduction of the medium M until the compression time has elapsed and the compression is released.

If all the media storage boxes 40 are being compressed when the medium M is introduced through the media input / output unit 13, the media storage box 40 having a short remaining compression time is selected and decompressed, M). As another example, a method of controlling to select the media storage box 40 having a set compression time is also possible.

The control unit also selects any of the plurality of media storage boxes 40 to which the medium M is to be withdrawn when the media M is taken out through the media input /

At this time, the controller selects a medium storage box 40 not being compressed by the support plate 151 among the plurality of media storage boxes 40, and draws out the medium M. That is, the withdrawal of the medium M may be stopped until the compression time of the media storage box 40 is being compressed and the compression is canceled.

If all the media storage boxes 40 are being compressed, the media storage box 40 having a short remaining compression time may be selected and temporarily uncompressed, and then the media M may be retrieved. As another example, a method of controlling to select the media storage box 40 having a long compression time is also possible.

Therefore, when the medium M is pulled out after temporarily releasing the compression during the compression, the compression can be performed again for the remaining compression time after the completion of the withdrawal of the medium M. At this time, as the medium M decreases, the compression time can also be reduced. For example, if half of the media M integrated during compression is drawn out, the compression time can also be reduced by half.

Hereinafter, a description will be given of a control method in a case where a plurality of media storage boxes 40 are provided in the financial device 1 of the present invention, but each of the media storage boxes 40 stores different kinds of media M do.

When the medium M is primarily drawn through the media input / output unit 13, the introduced medium M is introduced into one of the plurality of media storage boxes 40. This is referred to as a first media storage.

Next, when the medium M to be secondarily introduced through the medium input / output part 13 is a medium M different from the medium M which is primarily drawn in, M are led into a media storage box of the plurality of media storage boxes 40 other than the first media storage box. This is referred to as a second media storage. In this case, the first media storage box can decompress the medium (M) that is first drawn during the set compression time, and then decompress the media.

On the other hand, when the medium M that is secondarily introduced through the medium input / output unit 13 is the same type of medium M as the medium M that is primarily drawn in, Is introduced into the first media storage box. If the first media storage box is primarily compressing the media (M), the first media storage box temporarily releases the compression and draws in the secondary media (M). Since the first medium storage box temporarily uncompresses the medium M while the medium M is primarily inserted, the first and second media storage boxes are temporarily uncompressed during the compression of the medium M, And compresses the second-introduced medium (M). Here, if it is determined that the secondarily introduced medium is swollen, the media (M) compression time may be added according to the degree of swelling.

As described above, the support plate 151 compresses the medium M by determining the compression time according to the degree of swelling of the medium M, and releases the compression of the medium M when the determined compression time has elapsed. Hereinafter, the case where the compression by the support plate 151 is released when the compression time has not elapsed will be described.

First, the compression of the medium M by the support plate 151 can be released in the transaction preparation operation or the transaction end operation of the financial instrument 1.

In addition, if the idle time of the financial instrument 1 is maintained for a predetermined time or longer, the compression of the medium M can be released. The predetermined time may be approximately 1 minute, but is not limited thereto, and may be changed according to the setting of the user.

In addition, the medium M can be decompressed through a use termination command before the power source of the financial instrument 1 is turned off.

Thus, the medium M can be prevented from being excessively compressed by releasing the compression of the medium M by the support plate 151 at a certain point in time.

As described above, according to the medium storage box 40 of the present invention, the degree of bulging of the integrated medium M is determined, and the compression state and the compression time are determined and compressed using the support plate 151, can do. Thus, not only the amount of accumulation of the medium M can be increased, but also the phenomenon that the medium M is bent due to excessive compression can be prevented.
