Hereinafter, the storage module will be described in detail.

2 is a transparent perspective view of a storage module according to one embodiment.

Referring to FIG. 2, the storage module 110 may include a body 260, a door 230, and a door open sensing device 200.

Inside the body 260, a medium can be housed. For example, cash can be received inside the main body 260.

Such a medium may be inserted into the main body 260 through the door 230 or out of the main body 260.

The media may be imported or exported by the media processing module, and may be inserted or exported by the administrator.

For example, the storage module 110 may further include an inlet through which a medium for depositing is introduced and an outlet through which a medium to be withdrawn flows out. The storage module 110 is connected to the outlet of the storage module 110, The Donny media can be transferred to the media processing module. In other words, media can be introduced into or out of the storage module 110 by the media processing module. On the other hand, the manager can open the door 230 and can input or eject the medium from the outside.

In the normal case, the administrator may open the door 230 of the storage module 110 and then store the media into the interior of the body 260.

On the other hand, in an abnormal case, the deodorant of the outside can open the door 230 of the storage module 110 and then take out the medium stored in the main body 260.

FIG. 2 shows a door open detection device 200 for providing information to allow an administrator to recognize an abnormal door open or a door open count.

The door open detection device 200 included in the storage module 110 can detect that the door 230 of the storage module 110 is opened. Then, the door opening sensing device 200 can transmit the sensing signal in a manner that allows the manager to recognize the sensing signal.

For example, the door opening sensing device 200 can transmit a signal indicating that the door 230 is opened to a manager using a voice signal or an optical signal. Alternatively, after the storage module 110 is installed in the financial device, a signal may be transmitted to the controller of the financial device so that the manager can identify or confirm the information about the number of open doors and / or the number of doors.

The door open detection device 200 may further include an alarm device such as a speaker or a light emitting diode (LED).

As another example, the door open sensing device 200 may transmit a sensing signal to the financial device indicating the opening of the door 230. The financial instrument which receives the detection signal can send an alarm signal to an administrator terminal (for example, a server or a portable communication apparatus) so that an administrator can recognize the opening of the door 230.

The storage module 110 or the door openness sensing device 200 may be connected to a financial instrument by a communication line to transmit the sensing signal to the financial instrument. For example, when the door open detection device 200 is attached to a financial instrument, it may be connected to the financial instrument through a communication line. Alternatively, the financial instrument and the storage module 110 or the door open sensing device 200 can transmit and receive sensing signals through wireless communication.

The detailed configuration of the door open detection device 200 functioning as a security device in the storage module 110 will be described in further detail.

Referring to FIG. 2, the door open sensing device 200 may include a control circuit 210, a sensor 220, a power storage device 240, a power supply 250, and the like.

The sensor 220 senses opening and closing of the door 230 to generate an opening and closing signal or change the state according to the opening and closing of the door 230.

As a specific example, the sensor 220 may be a switch. When the sensor 220 is a switch, the sensor 220 can change the state according to the opening and closing of the door 230.

For example, when the door 230 is opened, the sensor 220 is in the switch-close state, and when the door 230 is closed, the sensor 220 can be in the switch-open state.

At this time, the door 230 may be provided with a sensor operation unit for turning the sensor 220 on and off. The sensor operating part may protrude from the door 230 to correspond to the sensor position.

The control circuit 210 may sense opening / closing of the door 230 according to an opening / closing signal received from the sensor 220 or a state of the sensor 220.

The control circuit 210 may be powered by power from the power storage device 240 or the power supply 250.

The control circuit 210 can receive power from the financial instrument when the storage module 110 is attached to the financial instrument. The power supply device 250 is a device that transmits power supplied from a financial instrument to the control circuit 210.

The power supply 250 may include a power line connection terminal and may be connected to the power line of the financial instrument through the power line connection terminal.

The power supply device 250 may transmit the voltage supplied from the financial instrument directly to the control circuit 210 or may convert the voltage to be transmitted to the control circuit 210 itself.

For example, if the financial instrument receives 3.3 V power, the power supply 250 can transfer the 3.3 V power directly to the control circuit 210. When the financial instrument supplies 24 V of power, the power supply 250 may convert the 24 V voltage to the 3.3 V voltage and then transmit the converted power to the control circuit 210. For this power conversion, the power supply 250 may further include a DC / DC conversion circuit, and may further include a regulator.

The control circuitry 210 may provide power to the control circuitry 210 via its own power storage device 240 when the storage module 110 is removed from the financial instrument.

Of course, in some cases, even when the door openness sensing device 200 receives power from the financial device, the power can be supplied from the financial device to the control circuit 210.

3 is a configuration diagram of an example of a power supply unit for supplying power to the control circuit in the door openness sensing apparatus.

The door opening sensing device may include a power supply unit 300 for supplying a driving voltage Vdd to the control circuit 210. [ The power supply unit 300 may include a power storage unit 240, a power supply unit 250, a diode circuit 340, and the like.

The power storage device 240 may include the battery 330 and may supply the driving voltage Vdd to the control circuit 210. [

The power supply device 250 includes a power line connection terminal 310 and a power conversion circuit 320 and may convert external power supplied from a financial instrument to a driving voltage Vdd and supply the external power to the control circuit 210 have.

The power supply selection circuit 340 may include a first diode D1 and a second diode D2.

The anode of the first diode D1 is connected to the output portion of the power supply 250 and the cathode may be connected to the drive voltage Vdd input portion of the control circuit 210. [ The anode of the second diode D2 may be connected to the output portion of the power storage device 240 and the cathode may be connected to the driving voltage Vdd input portion of the control circuit 210. [

By this power supply selection circuit 340, the output of either the power storage device 240 or the power supply device 250 can be limited.

For example, when the output voltage of the power supply 250 is high, the drive voltage Vdd of the control circuit 210 is determined as the output voltage of the power supply 250, It may not be able to output power to the circuit 210.

Conversely, when the output voltage of the power storage device 240 is high, the power supply 250 may not be able to output power to the control circuit 210.

The output voltage of the power supply 250 may be higher than the output voltage of the power storage device 240 when the door open sensing device is connected to the financial device and the power supply device 250 receives power from the financial device. In this case, the power supplied from the financial instrument is transmitted to the control circuit 210, and the power storage device 240 does not transmit the power to the control circuit 210.

Conversely, if the door open sensing device is disconnected from the financial instrument, the power supply 250 will not output power, so the power storage device 240 alone will deliver power to the control circuit 210.

The power supply selection circuit 340 selects the supply of power between the power supply 250 and the power storage device 240 but the power supplied to the control circuit 210 flows again to the power supply 250 And functions to prevent a backlash which enters or slips into the power storage device 240.

Alternatively, when the power storage device is constituted by a battery and the power supply device 250 is supplied with power from the financial device, the power supply device 250 supplies power to the control circuit 210 and the power storage device 240 The power supply selection circuit 340 can be configured to charge the power supply selection circuit 340.

Meanwhile, when the door opening sensing device is separated from the financial device, the door opening sensing device needs to be powered by the battery 330 of the power storage device 240, so it needs to be driven with low power.

4 is a configuration diagram of a control circuit according to an embodiment.

4, the control circuit may include a controller 410, an open signal generating circuit 420, a switch circuit 430, a signal holding circuit 440, a reset circuit 450, and the like.

The open signal generating circuit 420 is operated by the switch circuit 430 to generate a door open signal Sopen.

One side of the open signal generating circuit 420 is connected to the first node N2 and receives the driving voltage Vdd through the first node N2.

The other side of the open signal generating circuit 420 is connected to the controller 410. The door open signal Sopen is transmitted to the controller 410 through the other side of the open signal generating circuit 420.

Another side of the open signal generating circuit 420 is connected to the second node N2 and connected to the switch circuit 430 through the second node N2.

The open signal generating circuit 420 recognizes an electrical state change (for example, a voltage change) formed in the second node N2 and generates a door open signal Sopen.

The electrical state of the second node (N2) is determined by the switch circuit (430).

The switch circuit 430 is turned on and off when the door is opened and closed. The switch circuit 430 includes at least one switch, which can be connected or short-circuited depending on opening and closing of the switch.

One side of the switch circuit 430 may be connected to the low voltage line and the other side may be connected to the second node N2.

The switch circuit 430 lowers or increases the voltage of the second node N2 according to opening and closing of the door.

For example, the switch circuit 430 may lower the voltage of the second node N2 to a voltage near the voltage of the low-voltage line and disconnect the voltage of the second node N2 from the low-voltage line, It is possible.

The signal holding circuit 440 is connected in parallel with the switch circuit 430 and receives the door open signal Sopen to maintain the door open signal Sopen.

When the door is opened, the state of the switch circuit 430 is changed to generate a door open signal Sopen. If the door is closed before the manager confirms the door, the door open signal Sopen can be released.

The signal holding circuit 440 is connected in parallel to the switch circuit 430 so that the door open signal Sopen can be maintained even if the state of the switch circuit 430 is changed.

One side of the signal holding circuit 440 may be connected to the low voltage line and the other side may be connected to the second node N2.

The switch circuit 430 changes the voltage of the second node N2 to a predetermined voltage (for example, a low voltage) when the door is opened. The signal holding circuit 440 controls the switch circuit 430) and the open signal generating circuit 420. The open-

The reset circuit 450 resets the signal holding circuit 440.

When the controller 410 generates the reset signal Sreset, the reset circuit 450 causes the signal holding circuit 440 to be reset.

When the signal holding circuit 440 is reset, the door open signal Sopen is not maintained. However, if the door is kept open, the door open signal Sopen may be continuously generated by the switch circuit 430 even if the signal holding circuit 440 is reset.

5 is a first exemplary circuit configuration diagram of the control circuit.

Referring to FIG. 5, the control circuit may include a controller 410, an open signal generating circuit 420, and a switch circuit 430.

The open signal generating circuit 420 may include a first transistor Q1, a first impedance Z1, a third impedance Z3 and a fourth impedance Z4.

The switch circuit 430 may include a second impedance Z2 and a switch SW.

The control circuit transmits the open / close signal Sdoor to the door of the storage module to the controller 410 using the first transistor Q1 and the sensor.

The sensor may comprise a switch SW that is opened or closed in response to opening and closing of the door. The switch (SW) is opened when the door of the storage module is closed, and the switch (SW) is closed when the door is opened.

The first transistor Q1 includes an emitter terminal, a base terminal, and a collector terminal.

A driving voltage (Vdd) is supplied to the emitter terminal of the first transistor (Q1). As described with reference to Fig. 3, such a driving voltage Vdd may be supplied from a power supply device or a power storage device.

The base terminal of the first transistor Q1 may be connected to the low voltage line. The low voltage line means a line having a voltage lower than the driving voltage Vdd. The low voltage line may be a ground line, but in some cases it may be a bus line having a voltage lower than the driving voltage Vdd.

The first transistor Q1 may be turned on when the base terminal is connected to the low voltage line. When the base terminal has a lower voltage than the emitter terminal, the transistor turned on is generally referred to as a PNP type transistor, and the first transistor Q1 may be a PNP type transistor.

The switch SW is located between the base terminal of the first transistor Q1 and the low voltage line and controls the connection of the base terminal and the low voltage line of the first transistor Q1. Specifically, the switch SW is opened / closed according to the opening / closing of the door of the storage module. When the door is closed, the connection between the base terminal of the first transistor Q1 and the low voltage line is released. The switch SW connects the base terminal of the first transistor Q1 and the low voltage line when the door is opened.

According to the operation of the switch SW, the first transistor Q1 is turned off when the door is closed, and turned on when the door is opened.

The voltage formed at each node in each state of the switch SW will be described with reference to Figs. 5 and 6. Fig.

FIG. 6 is a diagram showing the voltage state of each node when the switch is opened in FIG. 5, and FIG. 7 is a diagram showing a voltage state of each node when the switch is closed in FIG.

For convenience of explanation, the emitter terminal of the first transistor Q1 is referred to as a first node N1, the base terminal thereof is referred to as a second node N2, and the collector terminal thereof is referred to as a third node N3.

In Fig. 6, the switch SW is open. Thus, the connection between the second node N2 - the base terminal - of the first transistor Q1 and the low voltage line is released.

The first node N1-the emitter terminal-of the first transistor Q1 and the second node N2 may be coupled through a first impedance Z1, the connection between the second node N2 and the low voltage line The voltage of the first node N1 is directly transmitted to the second node N2 through the first impedance Z1.

The first node N1 has a logic high voltage by the driving voltage Vdd. Since the voltage of the first node N1 is transferred to the second node N2 as the switch SW is opened, the second node N2 also has a logic high voltage.

According to this operation, the logic high HIGH voltage is applied to the base terminal of the first transistor Q1, so that the first transistor Q1 is turned off.

The collector terminal of the first transistor Q1 and the low voltage line may be connected to the third impedance Z3. The first transistor Q1 may be turned on when the first transistor Q1 is turned off. When the third node N3 fails to transfer the voltage to the third node N3, the third node N3 has a logic low voltage due to the low voltage line.

The output of the third node N3 is transmitted to the controller 410. As a result, when the door is closed, the controller 410 receives a logic low voltage as the open / close signal Sdoor.

On the other hand, referring to FIG. 7, when the switch SW is closed, the switch SW is closed according to the opening of the door.

When the switch SW is closed, the low voltage line is connected to the second node N2, and the base terminal of the first transistor Q1 has a logic low voltage. At this time, in order to reduce excessive current flow between the second node N2 and the low voltage line, or to prevent an excessive voltage difference between the emitter terminal and the base terminal of the first transistor Q1, And a second impedance Z2 may be further placed between the switch SW and the low voltage line, or between the switch SW and the low voltage line.

When the first transistor Q1 is turned on according to the logic low voltage, a logic high voltage is formed at the third node N3 and the controller 410 outputs a voltage of logic high at the third node N3, Signal (Sdoor). At this time, a fourth impedance Z4 may further be placed between the third node N3 and the controller 410 to prevent excessive current or voltage from being supplied from the third node N3 to the controller 410 .

5 through 7, in the control circuit having such a structure, when the door is closed, since the first transistor Q1 is turned off, no power (signal) is transmitted to the controller 410, . In the control circuit having such a structure, only when the door is opened, the first transistor Q1 is turned on and consumes power, thereby reducing power consumption.

On the other hand, there is a case in which a logic high (HIGH) is required to be maintained as an opening / closing signal (Sdoor) even after the door is once opened and then closed again. For this case, the control circuit may further include a signal holding circuit.

Fig. 8 is a circuit diagram showing a circuit configuration in which a signal holding circuit is further added in Fig.

Referring to FIG. 8, the control circuit may further include a signal holding circuit 440.

The signal holding circuit 440 can maintain the voltage state of the open / close signal Sdoor by controlling the base terminal voltage of the first transistor Q1 by using the voltage of the third node N3.

For example, when the third node N3 transmits a logic HIGH voltage to the controller 410 as the opening / closing signal Sdoor as the door is opened, the signal holding circuit 440 controls the third node N3, The logic high voltage of the first transistor Q1 may be received to continuously maintain the turn-on state of the first transistor Q1.

Fig. 9 is a diagram showing the detailed configuration of Fig. 8 and the voltage state of each node when the switch is closed.

Referring to FIG. 9, the signal holding circuit 440 may include a second transistor Q2. One side of the second transistor Q2 is connected to the second node N2 and the other side is connected to the low voltage line, and the base terminal voltage can be interlocked with the voltage of the third node N3.

Specifically, the third impedance Z3 connecting the third node N3 and the low-voltage line is composed of two impedances Z5 and Z6, and the fifth node Z5 and the sixth impedance Z6 meet. The fourth node N4 and the base terminal of the second transistor Q2 may be connected.

In this structure, when the voltage level of the third node N3 is at a logic high level, the fourth node N4 is also at a logic high level according to the voltage distribution of the fifth impedance Z5 and the sixth impedance Z6. (HIGH) voltage. When the fourth node N4 indicates a logic high, the second transistor Q2 is turned on and the second node N2 is connected to the low voltage line. When the second node N2 is connected to the low voltage line, the first transistor Q1 can be kept turned on even when the switch SW is opened.

At this time, since the second transistor Q2 and the switch SW are connected in parallel to each other between the second node N2 and the low voltage line, the second transistor Q2 is connected to the first transistor Q1 And the low-voltage line.

8 and 9, one side of the second transistor Q2 is connected to the second node N2. However, according to an embodiment, one side of the second transistor Q2 is connected to the second impedance Z2 and the switch RTI ID = 0.0 > SW. ≪ / RTI >

On the other hand, the control circuit may further include a reset circuit for releasing the signal holding circuit 440 from continuously transmitting the logic high (HIGH).

FIG. 10 is a circuit diagram showing a circuit configuration in which a reset circuit is further added in FIG.

Referring to FIG. 10, the control circuit may further include a reset circuit 450.

The reset circuit 450 can reset the open / close signal maintenance by the second transistor Q2 by controlling the connection of the base terminal of the second transistor Q2 and the low voltage line.

One side of the reset circuit 450 may be connected to the base terminal of the second transistor Q2 and the other side may be connected to the low voltage line. The reset circuit 450 may or may not connect the base terminal of the second transistor Q2 to the low voltage line according to the reset signal Sreset received from the controller 410. [

Fig. 11 is a diagram showing the detailed configuration of Fig. 10 and the voltage state of each node when the switch is opened.

Referring to FIG. 11, the reset circuit 450 may include a third transistor Q3. One side of the third transistor Q3 may be connected to the base terminal-fourth node N4 of the second transistor Q2, and the other side may be connected to the low voltage line.

A reset signal Sreset may be applied to the base terminal of the third transistor Q3. A seventh impedance Z7 and an eighth impedance Z8 are positioned between the base terminal and the low voltage line of the third transistor Q3 and a contact node-fifth node N5, where the two impedances Z7 and Z8 meet, The reset signal Sreset can be transmitted.

When the reset signal Sreset indicates a logic high, the third transistor Q3 may be turned on and the fourth node N4 may be connected to the low voltage line. Accordingly, the fourth node N4 indicates a logic low (LOW), and the second transistor Q2 can be turned off.

When the second transistor Q2 is turned off, the second node N2 becomes logic high and the first transistor Q1 can be turned off.

Finally, the third node N3 becomes a logic low and the logic low voltage can be transferred to the open / close signal Sdoor in accordance with the turn-off of the first transistor Q1.

On the other hand, when the storage module is separated from the financial instrument, the power supply selection device can cut off power supplied from the power supply to the control circuit and supply power from the power storage device. At this time, the door open detection device may be reset by the reset circuit so that the door can be initialized in a closed state, and the door open detection device may not be operated until the door is opened. Thus, the power consumption can be minimized even when the storage module is not opened or opened while moving.

In one embodiment, the storage module may be mounted on a tray of a financial instrument. The storage module can be connected to the signal and / or the power source through the tray and the connector. The financial instrument may include a mounting sensing device for sensing the mounting and detachment of the storage module. For example, the mounting sensing device may be provided in the storage module and the financial device, respectively, so that when the storage module is detached from the tray, the storage module can be detached from the tray through at least one signal connection line of the connector provided in the storage module. When the storage module is detached from the tray, the storage module can detect the detachment from the mounting detection device and initialize the door opening detection device. Alternatively, the door open detection device can detect the storage module removal and initialize itself. Alternatively, the user can confirm or reset whether the opening / closing confirmation device of the storage module is opened or closed through the interface.

When the door of the storage module separated from the financial instrument is opened, the door opening sensor is turned on by the sensor switch to generate the door opening signal.

The door opening detection device keeps the door opening signal by the signal holding circuit after the door opening signal is generated. At this time, the signal holding circuit keeps the door open signal even if the state of the sensor switch is changed because the door is closed.

When a storage module separated from a financial instrument is mounted on a financial instrument, when a user inputs a command for confirming whether the door of the storage module is open or closed through the interface, the door open detection device transmits a door open signal to the control section . Also, the user can operate the reset circuit of the door opening detection device through the interface to initialize the door opening detection device.

The embodiment of the present invention has been described above. According to this embodiment, the storage module is able to drive a security device, for example a door opening sensor, at low power. The storage module may be stably attached to a financial device, and may be supplied with power from a power storage device such as a battery. The storage module must reliably operate the security device irrespective of detachment from the financial device. To do so, the security device needs to be operated with low power. The storage module according to an embodiment of the present invention operates only when the door is opened by the sensor, especially the switch, so that low power driving is possible.
