Meanwhile, the main board <NUM> may be connected to the financial device <NUM> to receive power therefrom. The main board <NUM> may be disposed outside or inside the medium storage box <NUM>. When the main board <NUM> is disposed outside the medium storage box <NUM>, the configuration of receiving the power from the financial device <NUM> may be simplified by detecting that the medium storage box <NUM> is mounted on the financial device <NUM>.

The medium storage box <NUM> may further include a sub-board <NUM> for storing the medium storage box information. The sub-board <NUM> may be disposed inside the medium storage box <NUM>.

The medium storage box <NUM> may include the door opening detection unit <NUM>. When the medium storage box <NUM> is mounted on the financial device <NUM>, the door opening detection unit <NUM> may receive power from the financial device <NUM>. In addition, when the medium storage box <NUM> is unmounted from the financial device <NUM>, the door opening detection unit <NUM> may receive power from a battery <NUM> provided in the medium storage box <NUM>. Therefore, even when the medium storage box <NUM> is unmounted from the financial device <NUM>, the door opening detection unit <NUM> may transmit door opening information indicating that the cassette door <NUM> is opened to a microcomputer <NUM>.

The sub-board <NUM> may further include a door opening counter <NUM> for counting the opening of the cassette door <NUM>. Whenever the cassette door <NUM> is opened, the door opening detection unit <NUM> may detect that the cassette door <NUM> is opened. And the door opening counter <NUM> may count the number of times the cassette door <NUM> is opened.

The sub-board <NUM> may further include the battery <NUM> capable of supplying another power to the medium storage box <NUM>. When the medium storage box <NUM> is unmounted from the financial device <NUM>, the battery <NUM> may supply power to the medium storage box <NUM>. In detail, when the medium storage box <NUM> is unmounted from the financial device <NUM>, the power supplied from the financial device <NUM> is cut off. Moreover, the medium storage box <NUM> may receive power from the battery <NUM>. The battery <NUM> may be provided in, as an example, a rechargeable secondary battery.

Meanwhile, the sub-board <NUM> may be provided with a power driving circuit <NUM> for controlling power supplied to the medium storage box <NUM>.

<FIG> is a circuit configuration diagram schematically illustrating a power driving circuit according to the embodiment.

Referring to <FIG>, the power driving circuit <NUM> may include a power source selection unit <NUM> for selecting one between the power input unit <NUM> and the battery <NUM> to supply power to the medium storage box <NUM>.

The power source selection unit <NUM> may include a first diode D1 and a second diode D2. An input terminal of the first diode D1 may be connected to the power input unit <NUM>. Moreover, an output terminal of the first diode D1 may be connected to a first node n1. An input terminal of the second diode D2 may be connected to the battery <NUM>. Moreover, an output terminal of the second diode D2 may be connected to the first node n1. Therefore, the power source selection unit <NUM> may select a power unit having a higher voltage among the power input unit <NUM> and the battery <NUM>, and may supply power of the selected power unit to the medium storage box <NUM>.

Meanwhile, the input terminals of the first and second diodes D1 and D2 may denote anode terminals of the first and second diodes D1 and D2. Further, the output terminals of the first and second diodes D1 and D2 may denote cathode terminals of the first and second diodes D1 and D2.

In the embodiment, a first voltage applied to the power input unit <NUM> from the main power unit <NUM> of the financial device is higher than a second voltage of the battery <NUM>.

When the medium storage box <NUM> is mounted on the financial device <NUM>, the power input unit <NUM> is connected to the main power unit <NUM> of the financial device <NUM>. And, since the first voltage applied to the power input unit <NUM> from the main power unit <NUM> of the financial device <NUM> is larger than the second voltage of the battery <NUM>, the medium storage box <NUM> may receive the voltage of the main power unit <NUM> through the power input unit <NUM>.

On the contrary, when the medium storage box <NUM> is unmounted from the financial device <NUM>, no power is applied to the power input unit <NUM>. Therefore, the medium storage box <NUM> may receive only the power of the battery <NUM> by the power source selection unit <NUM>.

The power source selection unit <NUM> may select the power supply between the power input unit <NUM> and the battery <NUM>, but the power source selection unit <NUM> may also function to prevent the power supplied to the medium storage box <NUM> from flowing back into the power input unit <NUM> or from flowing back into the battery <NUM>.

The power driving circuit <NUM> may further include a power output unit <NUM> connected to the first node n1. The power output unit <NUM> may output power selected from the power source selection unit <NUM>. The power output from the power output unit <NUM> may be supplied to the sub-board <NUM>. In addition, the power output from the power output unit <NUM> may be supplied to the door opening detection unit <NUM>, which is to be described later.

The power driving circuit <NUM> may further include a voltage distribution unit <NUM> for distributing the voltage of the battery <NUM>. The voltage distribution unit <NUM> may include a first resistor R1, a second resistor R2, and a third resistor R3. The first resistor R1 and the second resistor R2 may be connected in parallel so that the power of the battery <NUM> may be primarily distributed. A primarily distributed first voltage VR1 of the battery <NUM> may be input to the power source selection unit <NUM>. Meanwhile, the second resistor R2 and the third resistor R3 are connected in parallel so that a primarily distributed second voltage VR2 of the battery <NUM> may be secondarily distributed. The secondarily distributed voltage may be transmitted to the microcomputer <NUM>. Meanwhile, the voltage distribution unit <NUM> distributes the voltage of the battery <NUM> to supply a voltage according to the standard of the sub-board <NUM>.

The power driving circuit <NUM> may further include a transistor Q0 for amplifying an input signal and transmitting the amplified signal to an output terminal. The battery <NUM> and the door opening detection unit <NUM> may be connected to the transistor Q0. In detail, the transistor Q0 may include a collector terminal C, a base terminal B, and an emitter terminal E. The input terminal of the battery <NUM> may be connected to the collector terminal C of the transistor Q0. In addition, the door opening detection unit <NUM> may be connected to the base terminal B of the transistor Q0. In addition, a low voltage line may be connected to the emitter terminal E of the transistor Q0. The low voltage line may be understood as ground.

The transistor Q0 may transmit an open signal of the cassette door <NUM> to the microcomputer <NUM> by a switch operation. In detail, when the cassette door <NUM> is opened, an open signal having a logic high voltage may be input to the base terminal B of the transistor Q0. At this time, the transistor Q0 may be turned on by the open signal. Moreover, the collector terminal C and the emitter terminal E of the transistor Q0 may be connected to each other by the open signal. Accordingly, the power driving circuit <NUM> may be provided with a closed circuit through which the battery <NUM> may be discharged. The power of the battery <NUM> may be supplied to the microcomputer <NUM> and the power source selection unit <NUM>. At this time, when the power of the battery <NUM> is supplied to the microcomputer <NUM>, the microcomputer <NUM> recognizes that the cassette door <NUM> is opened. In other words, when the power of the battery <NUM> is supplied to the microcomputer <NUM>, the microcomputer <NUM> may recognize the supplied power of the battery <NUM> as an open signal.

As another example, when the cassette door <NUM> is opened, an open signal from the door opening detection unit <NUM> may be input to the base terminal B. In addition, the open signal may be amplified by the transistor Q0 and transmitted to the battery <NUM>. The input signal level of the door opening detection unit <NUM> may be amplified by the transistor Q0. Although the signal level input to the door opening detection unit <NUM> is small, the microcomputer <NUM> may detect more accurately the opening of the cassette door <NUM>.

Meanwhile, the transistor Q0 may desirably denote a bipolar junction transistor (BJT). However, in addition to the bipolar junction transistor, a metal oxide silicon field effect transistor (MOSFET) and a junction field effect transistor (JFET) may be applied to the transistor Q0.

Referring again to <FIG>, the sub-board <NUM> may further include the cassette memory <NUM> in which the medium storage box information may be stored. The medium storage box information may include at least one of information such as, whether the cassette door <NUM> is opened, the number of times of opening the cassette door <NUM>, and the period of time when the cassette door <NUM> is open. As an example, during transport for collecting a medium of the medium storage box <NUM>, when the cassette door <NUM> is open, the number of times the cassette door <NUM> is open may be counted, and the counted information may be stored in the cassette memory <NUM>.

The cassette memory <NUM> may include a non-volatile memory. Therefore, even if the power supplied to the cassette memory <NUM> is shut off, the information stored therein may be maintained.

The sub-board <NUM> may further include a timer <NUM> that may count the date and time. The timer <NUM> may continuously receive power from the battery <NUM> regardless of whether the cassette door <NUM> is opened or closed. Thus, the date and time at which the medium storage box <NUM> is mounted on or unmounted from the financial device <NUM> may be stored in the cassette memory <NUM>. Also, the date and time when the cassette door <NUM> is opened may be stored in the cassette memory <NUM>.

Accordingly, an administrator may confirm the time and date when the cassette door <NUM> is opened, and the time and date when the medium storage box <NUM> is mounted on or unmounted from the financial device <NUM>, thereby confirming whether or not a medium of the medium storage box <NUM> is taken out. In addition, there is an advantage that the administrator is able to confirm the taken-out time and date when a medium of the medium storage box <NUM> is taken out.

The medium storage box <NUM> may further include the microcomputer <NUM> for controlling the main board <NUM> and the sub-board <NUM>. The microcomputer <NUM> may be desirably disposed on the sub-board <NUM>. Therefore, the main board <NUM> is connected to the microcomputer <NUM> by the connection means <NUM>, so that the main board <NUM> may transmit the information of the main board <NUM> to the microcomputer <NUM>. Based on the information of the main board <NUM>, the microcomputer <NUM> may control the sub-board <NUM>, that is, one of the door opening detection unit <NUM>, the door opening counter <NUM>, the battery <NUM>, the charging unit <NUM>, the cassette memory <NUM>, and the timer <NUM>.

In addition, the microcomputer <NUM> may transmit the information stored in the cassette memory <NUM> to the financial device <NUM> when the medium storage box <NUM> is mounted on the financial device <NUM>.

Hereinafter, a control method of the financial device <NUM> will be described, wherein the financial device <NUM> is controlled according to the opening of the cassette door <NUM>.

<FIG> is a flowchart illustrating the operation of the medium storage box according to the embodiment.

Referring to <FIG> and <FIG>, the medium storage box <NUM> may be unmounted from the financial device <NUM> in step S1. As an example, if the media storage number that may be stored in the medium storage box <NUM> is exceeded, the medium storage box <NUM> may be unmounted from the financial device <NUM>. Alternatively, the medium storage box <NUM> may be unmounted from the financial device <NUM> in order to supplement the medium to the medium storage box <NUM>.

The microcomputer <NUM> may operate in a charging mode in a state where the medium storage box <NUM> is mounted on the financial device <NUM> in step S3. When the first detection unit <NUM> detect that the medium storage box <NUM> is mounted on the cassette supporter <NUM>, the main power unit <NUM> of the financial device <NUM> may be connected to the power input unit <NUM> of the medium storage box <NUM>. The main power unit <NUM> is connected to the power input unit <NUM> so that the power of the financial device <NUM> may be supplied to the medium storage box <NUM>.

The power supplied to the power input unit <NUM> may be selected by the power source selection unit <NUM> and transmitted to the power output unit <NUM> connected to the first node n1. As an example, when the medium storage box <NUM> is mounted on the financial device <NUM>, the power input unit <NUM> is connected to the main power unit <NUM>. The first voltage of the main power unit <NUM> of the financial device <NUM> is higher than the second voltage of the battery <NUM>, wherein the first voltage is supplied to the power input unit <NUM>. Accordingly, the medium storage box <NUM> may receive the power of the power input unit <NUM> by the power source selection unit <NUM>. At this time, the microcomputer <NUM> may control the voltage of the power input unit <NUM> to be supplied to the battery <NUM> through the charging unit <NUM>. Therefore, the battery <NUM> is charged.

When the microcomputer <NUM> operates in the charging mode, the consumed power of the battery <NUM> is charged. Accordingly, even if the medium storage box <NUM> is separated from the financial device <NUM> later, the medium storage box <NUM> may be stably operated.

In a state where the medium storage box <NUM> is unmounted from the financial device <NUM>, the microcomputer <NUM> may operate in a standby mode in step S5. The standby mode may mean that the power of the battery <NUM> is not connected to the microcomputer <NUM> and the cassette memory <NUM>. That is, if a signal is not inputted to the base terminal B of the transistor Q0 due to a characteristic of the transistor Q0, the collector terminal C may not be connected to the ground. Therefore, since the power of the battery <NUM> may not be transmitted to the microcomputer <NUM> of the sub-board <NUM>, the power consumption of the battery <NUM> may be minimized.

The microcomputer <NUM> may maintain the standby mode until detecting that the cassette door <NUM> is opened in steps S5 and S7.

When the door opening detection unit <NUM> detects that the cassette door <NUM> is opened in step S7, the microcomputer <NUM> may be operated in a driving mode in step S9. The door opening detection unit <NUM> may receive power from the battery <NUM>. Accordingly, the door opening detection unit <NUM> may detect that the cassette door <NUM> is opened.

The door opening detection unit <NUM> may detect that the cassette door <NUM> is opened. At this time, an open detection signal may be input to the base terminal B of the transistor Q0. The open detection signal may be, for example, an open signal having a logic high voltage.

When the open signal is inputted to the base terminal B of the transistor Q0, the collector terminal C and the emitter terminal E of the transistor Q0 may be shorted to each other. Moreover, the collector terminal C and the emitter terminal E of the transistor Q0 are connected to each other. Accordingly, the power driving circuit <NUM> may be provided with a closed circuit for supplying power from the battery <NUM>. Therefore, the power of the battery <NUM> may be transmitted to the microcomputer <NUM>. When the power of the battery <NUM> is supplied to the microcomputer <NUM>, the microcomputer <NUM> may recognize that the cassette door <NUM> is opened. In other words, when the power of the battery <NUM> is supplied to the microcomputer <NUM>, the microcomputer <NUM> may recognize the supplied power of the battery <NUM> as an open signal.

The microcomputer <NUM> may store the opening of the cassette door <NUM> in the cassette memory <NUM>. In addition, the microcomputer <NUM> refers to whether the cassette door <NUM> is open or not, which is stored in the cassette memory <NUM>, and the number of times the cassette door <NUM> is opened may be stored in the cassette memory <NUM>.

As an example, when the cassette door <NUM> is opened, the microcomputer <NUM> may receive the open signal by the door opening detection unit <NUM>. The microcomputer <NUM> may store the information that the cassette door <NUM> is opened in the cassette memory <NUM>. And, the door opening counter <NUM> may count the number of times the cassette door <NUM> is opened.

The number of times the cassette door <NUM> is opened may be stored in the cassette memory <NUM> by the door opening counter <NUM>. Further, the time at which the cassette door <NUM> is opened may be counted by the timer <NUM>, and the counted time may be stored in the cassette memory <NUM>.

When the cassette door <NUM> is closed, the microcomputer <NUM> may be switched to the standby mode. The power supplied to the microcomputer <NUM> and the cassette memory <NUM> may be shut off again when the microcomputer <NUM> is switched to the standby mode.

Since the microcomputer <NUM> is in the standby mode until the cassette door <NUM> is opened, the power of the battery <NUM> may be efficiently utilized. Furthermore, discharge of the battery <NUM> may be minimized even when the medium storage box <NUM> is transported for a long time.

The microcomputer <NUM> may be operated in the charging mode in step S13 when the medium storage box <NUM> is mounted on the financial device <NUM> in step S13. By charging the battery, it is possible to stably count the opening of the cassette door <NUM> even if the medium storage box <NUM> is unmounted from the financial device <NUM>. The microcomputer <NUM> is capable of storing the counted information in the cassette memory <NUM>. At least one of the information on which the cassette door <NUM> is opened and the counted number of times may be stored in the cassette memory <NUM> as medium storage box information.

The microcomputer <NUM> may transmit the medium storage box information stored in the cassette memory <NUM> to the main memory <NUM> in step S15 when the medium storage box <NUM> is mounted on the financial device <NUM> in step S13. The microcomputer <NUM> may transmit the medium storage box information stored in the cassette memory <NUM> to the main memory <NUM> via the first communication unit <NUM>. The medium storage box information transmitted to the main memory <NUM> may be displayed on the user interface <NUM> or displayed on another administrator apparatus. Therefore, when the medium storage box <NUM> is mounted on the financial device <NUM>, an administrator may confirm whether or not a medium is taken out of the medium storage box <NUM> using the medium storage box information. As an example, when an intruder takes out a medium forcibly from a medium storage box in transit, the administrator may confirm that the medium has been taken out from the medium storage box and may determine that the medium has been taken out from the intruder. In addition, there is an advantage that the administrator is able to confirm the taken-out time using the information when the cassette door <NUM> is opened.

Hereinafter, an example useful for understanding the invention will be described.

In the example, the same parts as those of the prior embodiment are omitted, and the differences are mainly described.

The power input unit <NUM> and the battery <NUM> may be connected to the first and second diodes D1 and D2, respectively. The power source selection unit <NUM> may select a power unit having a higher voltage among the power input unit <NUM> and the battery <NUM>, and may supply power of the selected power unit to the medium storage box <NUM>.

<FIG> is a configuration diagram of the sub-board according to the example.

Referring to <FIG>, a control circuit <NUM> of the door opening detection unit <NUM> may include an open signal generation circuit <NUM> for generating an open signal Sopen. When the cassette door <NUM> is opened, the open signal generation circuit <NUM> may generate an open signal Sopen. One side of the open signal generation circuit <NUM> is connected to a control circuit first node nc1. Further, the open signal generation circuit <NUM> may receive a driving voltage Vdd through the control circuit first node nc1. The driving voltage Vdd may be any one of the voltage of the financial device <NUM> and the voltage of the battery <NUM> selected by the power source selection unit <NUM>.

Another side of the open signal generation circuit <NUM> may be connected to a microcomputer <NUM>. The open signal Sopen may be transmitted to the microcomputer <NUM> through the other side of the open signal generation circuit <NUM>. When the open signal Sopen is transmitted to the microcomputer <NUM>, the microcomputer <NUM> may store information (or open information) in which the cassette door <NUM> is opened in a cassette memory <NUM> provided in the sub-board <NUM>. Moreover, when the medium storage box <NUM> is mounted on the financial device <NUM>, the information stored in the cassette memory <NUM> may be transmitted to the financial device <NUM>. In another example, the microcomputer <NUM> may have a function of a storage medium so as to store the opening information of the cassette door <NUM>.

Meanwhile, still another side of the open signal generation circuit <NUM> may be connected to a control circuit second node nc2. The control circuit second node nc2 may be connected to a switch circuit <NUM> operated on the basis of opening or closing of the cassette door <NUM>. The switch circuit <NUM> will be described later.

Meanwhile, the open signal generation circuit <NUM> may generate the open signal Sopen by recognizing an electrical state change (for example, a voltage change) formed in the control circuit second node nc2. The electrical state of the control circuit second node nc2 may be determined by the switch circuit (<NUM>).

The control circuit <NUM> may further include the switch circuit <NUM>. The switch circuit <NUM> may be connected to the door opening detection unit <NUM>. Then, based on whether the cassette door <NUM> is opened or closed, the switch circuit <NUM> may be turned on or off. In detail, the switch circuit <NUM> may include at least one switch connected to the door opening detection unit <NUM>. The switch SW may be opened or closed by the door opening detection unit <NUM>. The switch circuit <NUM> may be turned on or off according to the open or closed state of the switch SW.

One side of the switch circuit <NUM> may be connected to the low voltage line. The other side of the switch circuit <NUM> may be connected to the control circuit second node nc2. The switch circuit <NUM> may form the voltage of the control circuit second node nc2 to be low or high based on the opening or closing of the cassette door <NUM>. For example, the switch circuit <NUM> may form the voltage of the control circuit second node nc2 to be low near the voltage of the low voltage line, depending on the opening or closing of the cassette door <NUM>. In addition, the switch circuit <NUM> may separate the voltage of the control circuit second node nc2 from the low voltage line.

<FIG> is a first exemplary circuit configuration diagram of a control circuit of the door opening detection unit according to the example.

Referring to <FIG>, the control circuit <NUM> may include the open signal generation circuit <NUM> and the switch circuit <NUM>.

The open signal generation circuit <NUM> may include a first transistor Q1, a first impedance Z1, a second impedance Z2, a third impedance Z3, and a fourth impedance Z4.

The switch circuit <NUM> may include the second impedance Z2 and the switch SW. The switch SW may be opened or closed based on a signal generated by the door opening detection unit <NUM>. For example, the door opening detection unit <NUM> may detect that the cassette door <NUM> is opened. At this time, the door opening detection unit <NUM> may generate an open signal Sopen to close the switch SW. Conversely, the door opening detection unit <NUM> may detect that the cassette door <NUM> is closed. At this time, the door opening detection unit <NUM> may open the switch SW by generating a closing signal.

In summary, the control circuit <NUM> may transmit an open detection signal Sdoor for the cassette door <NUM> to the microcomputer <NUM> based on a signal generated by the door opening detection unit <NUM>.

The open signal generation circuit <NUM> may include a first transistor Q1 connected to the switch circuit <NUM> and transmitting an open detection signal Sdoor to the microcomputer <NUM>.

The first transistor Q1 may include an emitter terminal E, a base terminal B, and a collector terminal C. And, the first transistor Q1 may be a PNP type transistor which is turned on when the base terminal B of the first transistor Q1 has a lower voltage than the emitter terminal E.

A driving voltage Vdd may be supplied to the emitter terminal E of the first transistor Q1. As described above, the driving voltage Vdd may be applied from the financial device <NUM> or the battery <NUM>.

The base terminal (B) of the first transistor (Q1) may be connected to the low voltage line. The low voltage line may mean a line that has a lower voltage than the driving voltage Vdd. The low voltage line may be a ground line, but may be a bus line having a voltage lower than the driving voltage Vdd in some cases.

When the base terminal B of the first transistor Q1 is connected to the low voltage line, the first transistor Q1 may be turned on.

The switch SW may be disposed between the base terminal B of the first transistor Q1 and the low voltage line. And the switch SW may control the connection between the base terminal B of the first transistor Q1 and the low voltage line. Specifically, when the cassette door <NUM> is closed, the switch SW may be closed by the door opening detection unit <NUM>. Accordingly, the connection between the base terminal B of the first transistor Q1 and the low voltage line may be released. Conversely, when the cassette door <NUM> is opened, the switch SW may be opened by the door opening detection unit <NUM>. Accordingly, the base terminal B of the first transistor Q1 and the low voltage line may be connected.

In summary, according to the operation of the switch SW, when the cassette door <NUM> is opened, the first transistor Q1 is turned on. Conversely, when the cassette door <NUM> is closed, the first transistor Q1 is turned off.

The voltage formed at each node of the control circuit <NUM> based on each state of the switch SW will be described with reference to <FIG> and <FIG>.

Hereinafter, for convenience of explanation, the emitter terminal E of the first transistor Q1 is referred to as a control circuit first node nc1. The base terminal B of the first transistor Q1 is referred to as a control circuit second node nc2. The collector terminal C of the first transistor Q1 is referred to as a control circuit third node nc3.

<FIG> is a circuit diagram illustrating a voltage state of each node when the switch is opened in <FIG>. <FIG> is a circuit diagram illustrating a voltage state of each node when the switch is closed in <FIG>.

First, referring to <FIG>, the switch SW may be opened according to the closing of the cassette door <NUM>. Thus, the connection between the control circuit second node nc2 and the low voltage line may be released.

The control circuit first node nc1 and the control circuit second node nc2 may be connected through the first impedance Z1. Thus, when the connection between the control circuit second node nc2 and the low voltage line is released, the voltage of the control circuit first node nc1 may be directly transmitted to the second node nc2 through the first impedance Z1.

The control circuit first node nc1 may have a logic high voltage by the driving voltage Vdd. The voltage of the control circuit first node nc1 may be transferred as it is to the control circuit second node nc2 according to the opening of the switch SW. Accordingly, the control circuit second node nc2 may have a logic high voltage. Therefore, when a logic high voltage is applied to the base terminal B of the first transistor Q1, the first transistor Q1 may be turned off.

The control circuit third node nc3 and the low voltage line may be connected to the third impedance Z3. When the first transistor Q1 fails to transfer the voltage to the control circuit third node nc3 according to the turn-off of the first transistor Q1, the control circuit third node nc3 may have a logic low voltage by the low voltage line. The output of the control circuit third node nc3 may be transmitted to the microcomputer <NUM>. That is, when the cassette door <NUM> is closed, the microcomputer <NUM> receives the logic low voltage as an open detection signal Sdoor.

Meanwhile, referring to <FIG>, the switch SW may be closed by opening the cassette door <NUM>. Accordingly, the control circuit second node nc2 and the low voltage line may be connected.

When the control circuit second node nc2 and the low voltage line are connected, the base terminal B of the first transistor Q1 has a logic low voltage.

Meanwhile, a second impedance Z2 may be disposed between the control circuit second node nc2 and the switch SW. Alternatively, the second impedance Z2 may be disposed between the switch SW and the low voltage line. By the second impedance Z2, an excessive current flow between the control circuit second node nc2 and the low voltage line may be reduced. In addition, an excessive voltage difference between the emitter terminal E and the base terminal B of the first transistor Q1 may be prevented.

When the logic low voltage of the base terminal B of the first transistor Q1 is applied, the first transistor Q1 may be turned on. Therefore, a logic high voltage is formed in the control circuit third node nc3. Moreover, the microcomputer <NUM> may receive the logic high voltage as an open detection signal Sdoor. At this time, the open detection signal Sdoor of the logic high voltage may mean the open signal Sopen.

Meanwhile, in order to prevent an excessive current or voltage from being supplied from the control circuit third node nc3 to the microcomputer <NUM>, a fourth impedance Z4 may be further disposed between a control circuit fourth node nc4 and the microcomputer <NUM>.

As shown in <FIG>, when the cassette door <NUM> is closed, the first transistor Q1 of the control circuit <NUM> is turned off, so that power (signal) is not transmitted to the microcomputer <NUM>. That is, only when the cassette door <NUM> is opened from the cassette body <NUM>, the first transistor Q1 may be turned on to consume electric power. Therefore, there is an advantage that the power consumed by the financial device <NUM> or the battery <NUM> connected to the medium storage box <NUM> may be reduced.

<FIG> is a circuit diagram in which a signal holding circuit is added to <FIG>.

Referring to <FIG>, the control circuit <NUM> may further include a signal holding circuit <NUM> for continuously transmitting the open signal Sopen to the microcomputer <NUM>. The signal holding circuit <NUM> may be connected in parallel with the switch circuit <NUM>. In detail, one side of the signal holding circuit <NUM> may be connected to the low voltage line. Moreover, the other side of the signal holding circuit <NUM> may be connected to the control circuit second node nc2. When the cassette door <NUM> is opened from the cassette body <NUM>, the voltage of the control circuit second node nc2 may be changed to a set voltage (for example, a low voltage). At this time, the signal holding circuit <NUM> may maintain the voltage of the control circuit second node nc2 which is formed between the switch circuit <NUM> and the open signal generation circuit <NUM> when the cassette door <NUM> is opened. Unless a separate command is input from the microcomputer <NUM>, the voltage of the control circuit second node nc2 can be maintained so that the open signal Sopen is continuously generated. Accordingly, even when the cassette door <NUM> is closed without a separate command of the microcomputer <NUM>, the open signal Sopen may be prevented from being released.

The signal holding circuit <NUM> may control the voltage of the base terminal B of the first transistor Q1 by using the voltage of the control circuit third node nc3. Accordingly, the voltage state of the open detection signal Sdoor may be kept constant.

For example, the cassette door <NUM> may be opened from the cassette body <NUM>. At this time, the logic high voltage of the control circuit third node nc3may be transmitted to the microcomputer <NUM> as an open detection signal Sdoor. Moreover, the signal holding circuit <NUM> may receive the logic high voltage of the control circuit third node nc3 to continuously maintain the turn-on state of the first transistor Q1.

<FIG> is a circuit diagram illustrating a detailed configuration of <FIG> and the state of the voltage of each node when the switch is closed.

Referring to <FIG>, the signal holding circuit <NUM> may include a second transistor Q2. Moreover, the second transistor Q2 may include a collector terminal C, an emitter terminal E, and a base terminal B. The collector terminal C of the second transistor Q2 may be connected to the control circuit second node nc2. Moreover, the emitter terminal E of the second transistor Q2 may be connected to the low voltage line. The base terminal B of the second transistor Q2 may be interlocked with the voltage of the control circuit third node nc3.

Specifically, the control circuit third node nc3 and the third impedance Z3 connecting the low voltage line may be composed of two impedances Z5 and Z6. And the base terminal B of the second transistor Q2 may be connected to the control circuit fourth node nc4 where the fifth impedance Z5 and the sixth impedance Z6 meet.

When the control circuit third node nc3 indicates a logic high voltage, the control circuit fourth node nc4 may have a logic high voltage according to voltage distribution of the fifth impedance Z5 and the sixth impedance Z6. When the control circuit fourth node nc4 indicates a logic high voltage, the second transistor Q2 is turned on so that the control circuit second node nc2 and the low voltage line may be connected. Therefore, when the control circuit second node nc2 and the low voltage line are connected, the first transistor Q1 may be kept turned on even if the switch SW is opened.

At this time, the second transistor Q2 and the switch SW are connected in parallel to each other between the second node nc2 and the low voltage line. Therefore, even if the switch SW is opened, the second transistor Q2 may connect the base terminal B of the first transistor Q1 and the low voltage line.

In <FIG> and <FIG>, one side of the second transistor Q2 is shown connected to the control circuit second node nc2. However, depending on an example, one side of the second transistor Q2 may be connected to a contact node between the second impedance Z2 and the switch SW. The second transistor Q2 may be, as an example, an npn type transistor.

<FIG> is a circuit configuration diagram in which a reset circuit is further added in <FIG>.

Referring to <FIG>, the control circuit <NUM> may further include a reset circuit <NUM> for resetting the signal holding circuit <NUM>. When the microcomputer <NUM> generates a reset signal Sreset, the reset circuit <NUM> may reset the signal holding circuit <NUM>. When the signal holding circuit <NUM> is reset, the open signal Sopen is no longer maintained. However, if the cassette door <NUM> is kept open from the cassette body <NUM>, even if the signal holding circuit <NUM> is reset, the open signal Sopen may still be generated by the switch circuit <NUM>.

The reset circuit <NUM> controls the connection of the base terminal B of the second transistor Q2 and the low voltage line, so that the open detection signal Sdoor may be reset by the second transistor Q2.

One side of the reset circuit <NUM> may be connected to the base terminal B of the second transistor Q2. Moreover, the other side of the reset circuit <NUM> may be connected to the low voltage line. The reset circuit <NUM> may determine whether to connect the base terminal B of the second transistor Q2 and the low voltage line based on the reset signal Sreset received from the microcomputer <NUM>.

<FIG> is a circuit diagram illustrating a detailed configuration of <FIG> and a voltage state of each node when the switch is opened.

Referring to <FIG>, the reset circuit <NUM> may include a third transistor Q3. The third transistor Q3 may include a collector terminal C, an emitter terminal E, and a base terminal B. Moreover, the collector terminal C of the third transistor Q3 may be connected to the base terminal B of the second transistor Q2. In other words, the collector terminal C of the third transistor Q3 may be connected to the control circuit fourth node nc4.

The reset signal Sreset may be input to the base terminal B of the third transistor Q3. A seventh impedance Z7 and an eighth impedance Z8 may be placed between the base terminal B of the third transistor Q3 and the low voltage line. And the reset signal Sreset may be input from the microcomputer <NUM> to a control circuit fifth node nc5, which is a contact node where the seventh impedance Z7 and the eighth impedance Z8 meet.

When the voltage of the reset signal Sreset indicates a logic high, the third transistor Q3 may be turned on. At this time, the control circuit fourth node nc4 and the low voltage line may be connected to each other. Therefore, the control circuit fourth node nc4 may represent a logic low voltage (LOW). Moreover, the second transistor Q2 may be turned off.

When the second transistor Q2 is turned off, the control circuit second node nc2 may become logic high. Accordingly, the first transistor Q1 may be turned off.

In summary, a logic low voltage is transferred to the control circuit third node nc3 according to the turn-off of the first transistor Q1. Moreover, a logic low voltage may be transmitted to the microcomputer <NUM> as an open detection signal Sdoor.

Meanwhile, when the medium storage box <NUM> is unmounted from the financial device <NUM>, the power of the battery <NUM> may be supplied to the power output unit <NUM> by the power source selection unit <NUM>. At this time, the door opening detection unit <NUM> may be reset by the reset circuit <NUM>. In other words, the door opening detection unit <NUM> may be initialized by the reset circuit <NUM>. Therefore, the door opening detection unit <NUM> may not be operated until the cassette door <NUM> is opened from the cassette body <NUM>. Therefore, the power consumed by the battery <NUM> may be reduced even if the medium storage box <NUM> is not opened or opened during movement.
