Is connected to a remaining amount detecting unit 34 as remaining amount detecting means.
The output side of the remaining amount detection unit 34 is connected to a CPU control unit 33, and the CPU control unit 33 is connected to the L
The ED 35 is turned on and off. L
The ED 35 generates a pre-alarm and is mounted at a position visible from the outside of the apparatus. This LED
A spare battery 36 supplies power to 35.

Next, the operation and use of the medium storage device will be described. The CPU control unit 33 monitors whether there is any fraud using the security sensor 28 and the key sensor 29. When the theft is detected, the CPU control unit 33 provides a control signal to the alarm output unit 30 to sound a buzzer or stain a banknote.
In a normal state, the security sensor 28, the key sensor 29, and C
The voltage for driving the PU control unit 33 is low, and the power consumption is very small. As a method of further reducing power consumption, a method of intermittently monitoring the security sensor 28 and the key sensor 29 can be considered. However, the voltage of the battery 31 gradually decreases. That is, the remaining battery power decreases.

FIG. 7 is a diagram showing the output voltage of the battery 31 in FIG. When the power supply voltage output from the battery 31 decreases and becomes lower than the minimum drive voltage 37 of the alarm output unit 30, the alarm output unit 30 does not function. Therefore, when the medium storage device 20 is stolen, it is possible to escape the alarm by being left for a long time. Further, there is a possibility that the voltage may be reduced during storage in a warehouse or as a spare.

The remaining amount detecting section 34 detects the output voltage of the battery 31 and supplies it to the CPU control section 33. CPU controller 33
Is set to a pre-alarm generation voltage 38 in which the power supply voltage of the battery 31 is set to a level higher than the minimum drive voltage 37. When the output voltage of the battery 31 becomes the pre-alarm generation voltage 38, Activate 36,

[Second Embodiment] FIG. 8 shows a second embodiment of the present invention.
FIG. 3 is a circuit diagram illustrating a security circuit of the medium storage device according to the first embodiment, in which components common to those in FIG. 1 illustrating the first embodiment are denoted by common reference numerals. This medium storage device 40
Is provided with a non-lock switch 41 inside the box, and changes the LED 35 of the first embodiment to the LED 42. Other configurations are the same as those of the first embodiment. The switch 41 is for causing the LED 42 to emit light only when operated. The LED 42 is installed inside the medium storage device 40, and emits light to a person who operates the switch 41 to generate a pre-alarm.

Next, the operation of the medium storage device shown in FIG. 8 will be described. In the above-described first embodiment, the LED 35 emits light unconditionally when the power supply voltage output from the battery 31 decreases. However, the LED 35 is left unattended at a place where the apparatus is installed for a long time, or shipment is extended and stored in a warehouse. When the maintenance period is extended or the storage is performed for a long period of time for maintenance, a pre-alarm may occur without the maintenance staff noticing. In this case, the power supply voltage of the batteries 31 and 36 decreases, and finally the alarm output unit 3
0 may be activated.

However, in the medium storage device 40, since the switch 41 is provided, for example, when the switch is depressed when the maintenance staff stores the bill, the output voltage of the battery 31 becomes the pre-alarm generation voltage 38. In the case, L
The ED 42 emits light. Therefore, a pre-alarm occurs only when a maintenance person or the like is present, and a pre-alarm does not occur in a storage location such as a factory without being noticed.

As described above, in the second embodiment,
Since the switch 41 is provided, the occurrence of the pre-alarm is limited to a case where a maintenance person is present. Therefore, the battery 36
You can extend the life of the device. In addition, since the switch 41 is installed inside the apparatus, even if an attempt is made to act illegally, it cannot be operated and the deterrent effect is not spoiled. Further, since the switch 41 is a non-lock switch, it is possible to prevent a maintenance person or the like from forgetting to turn off the switch 41. Further, since the LED 42 is also provided inside the apparatus, information is leaked only to maintenance personnel, and therefore, the anti-theft property is excellent. Further, if there is an abnormality in the circuit, it is possible to check the operation by turning off the light, turning on the light during the pre-alarm, blinking and using the light properly in the normal state.

[Third Embodiment] A medium storage device according to a third embodiment of the present invention has the same configuration as that of the first embodiment. However, based on the output information of the security sensor 28, the key sensor 29, and the remaining amount detection unit 34, the CPU control unit 33
Function as open / closed state detection means for detecting the open / closed state of the
The output information causes the LED 35 to emit light. In the medium storage device of the first embodiment, as described in the second embodiment, the LED 35 emits light unconditionally when the power supply voltage output from the battery 31 decreases. If a person is left unattended, or a shipment is extended and stored in a warehouse for a long time, or stored for a long period of time for maintenance, a pre-alarm may occur without the maintenance staff noticing. In this case, battery 3
There is a possibility that the power supply voltage of the power supply 6 decreases and the alarm output unit 30 is finally activated.

However, in the medium storage device of the third embodiment, the CPU control unit 33 allows the maintenance staff or the like to perform the maintenance of the bills and the storage of the bills by the maintenance person based on the information from the security sensor 28 and the key sensor 29 in a regular manner. Is opened, and at this time, if the voltage detected by the remaining amount detection unit 34 is, for example, equal to or higher than a predetermined voltage value, the LED 35 emits light for a certain period of time. Blinks for a certain period of time. In this way, not only can the remaining ticks of the battery 31 be generated, but also the failure of the LED 35 and the circuit can be checked. Further, similarly to the second embodiment, a pre-alarm does not occur without being noticed in a storage place such as a factory.

As described above, in the third embodiment,
The CPU control unit 33 controls the security sensor 28, the key sensor 29,
Since the LED 35 is caused to emit light based on the output information of the remaining amount detection unit 34, a pre-alarm is generated only when a maintenance person is present. Therefore, the life of the battery 36 can be extended. In addition, even if a maintenance person or the like does not operate the switch 41 consciously as in the second embodiment, the battery 3 can be used.
It is possible to perform the remaining amount check of 1. In addition,
Even if the light emission state of the LED 35 is overlooked, the remaining amount can be checked only by opening and closing the door 24 again, so that the operability is excellent.

[Fourth Embodiment] FIG. 9 shows a fourth embodiment of the present invention.
FIG. 3 is a circuit diagram of a security circuit of the medium storage device according to the first embodiment, in which components common to those in FIG. 1 according to the first embodiment are denoted by common reference numerals. This medium storage device 50
Is a changeover switch such as a dip switch 5
1 is provided. The switch 51 is connected to the
0, and is connected between the battery 31 and the input terminal of the CPU control unit 33 so that the voltage of the battery 31 is input to the CPU control unit 33 when turned on.
The configuration of other parts of the medium storage device 50 is the same as that of the first embodiment.

Next, the operation of the medium storage device 50 will be described. When the switch 51 is turned off and the voltage of the battery 31 is not input, the CPU control unit 33 does not generate a pre-alarm and does not activate the alarm output unit 30. For this reason, the switch 51 is set to the off-state when it is stored in a warehouse or the like before shipment or when it is set in the automatic teller machine as a spare.

For example, a staff member turns on the switch 51 when shipping the medium storage device 50, and a maintenance person or the like during actual operation. The switch 51 that is turned on transmits the output voltage of the battery 31 to the input terminal of the CPU control unit 33. In this state, the CPU control unit 33 operates in the same manner as in the first embodiment. At the time of actual operation, the maintenance staff always checks the settings. Therefore, even if the power supply voltage of the battery 31 drops during storage, a pre-alarm is noticed, so that the battery 31 can be replaced.

As described above, in the fourth embodiment,
The medium storage device of the first embodiment has a
1 to generate a pre-alarm and activate the alarm output unit 30 by turning on and off the switch 51;
It is possible to select and set not to perform. This prevents an alarm from being erroneously raised at the time of storage in a factory warehouse or the like, so that the same effect as in the first embodiment can be achieved only during actual operation. In addition, since the switch 51 is arranged inside the medium storage device 50, a person who tries to perform some kind of injustice cannot be distinguished and does not impair the deterrent effect of crime.

[Fifth Embodiment] In the medium storage device of the first embodiment described above, only one set of the security sensor 28 and the key sensor 29 for detecting a crime is incorporated.
In the fifth embodiment of the present invention, a plurality of security sensors 28 and key sensors 29 are provided, respectively, and the other configuration is the same as that of the first embodiment. And the CPU control unit 33
When an abnormality is detected by only one of the security sensor 28 and the key sensor 29, the LED 35 is illuminated so that the alarm output unit 30 is not driven.
Alternatively, the alarm output unit 30 only when the detection is performed by the key sensor 29
To drive.

In the first embodiment, it is sufficient to start the alarm output unit 30 upon detecting a crime. However, for example, when assembling at a factory, there is a risk that the sensors 28 and 29 may malfunction by mistake. However, in the medium storage device of the fifth embodiment, the security sensor 28 and the key sensor 29 are provided in a plurality of systems, respectively. Therefore, even if one system detects a crime by mistake, the alarm output unit 30 is activated. Instead, the pre-alarm is notified by causing the LED 35 to emit light by the spare battery 36. When attempting destruction or fraud, the destruction is continued until the final target banknote can be obtained. Therefore, the alarm output unit 30 is activated only when a crime is detected by the security sensors 28 or the key sensors 29 of a plurality of systems. .

As described above, in the fifth embodiment,
A plurality of security sensors 28 and a plurality of key sensors 29 are provided, and the alarm output unit 30 is activated only when a crime is detected by the plurality of security sensors 28 or the key sensors 29. Alarm output unit 30
In addition to reducing the risk of starting the assembly, the burden on the assembly operator can be reduced and the reliability can be improved.

[Sixth Embodiment] The basic configuration of a medium storage device according to a sixth embodiment of the present invention is the same as that of the first embodiment. Is stored, and the alarm output unit 30 is activated in response to a change in the state of the medium storage device. When replenishing or collecting banknotes in the media storage device, use a key to stop the anti-theft function, but use an auto-lock mechanism to improve the workability of maintenance staff etc. Is thought enough. In the automatic lock mechanism, the key comes out of the keyhole after the lock is released, and when the door 24 is closed, the lock can be performed without using the key.

Normal maintenance personnel attach a key to the waist, remove the key only when necessary, and use it, or keep various types of keys, so they are often stored using a key box. Therefore, if an automatic lock mechanism is provided, the key is returned to the waist or the key box immediately after unlocking, thereby leading to prevention of loss.
In addition, when collecting and replenishing banknotes to a plurality of medium storage devices at a time in a warehouse or a storage place, a plurality of these medium storage devices are arranged and unlocked. For the same model,
In many cases, the same key can be used, and work efficiency is good if it is separated from those who open, refill, and lock. In this case, if an automatic lock mechanism is provided, the door 24 may be closed from the end, which is simple. In the auto lock mechanism, a locked state is set internally when the key is pulled out.

FIG. 10 is a flowchart for determining the activation of the alarm output unit. In the first embodiment which does not consider the auto-lock mechanism, when the destruction sensor 28a or the door sensor 28b detects the destruction or opening of the door 24 in a state where the key is locked, the alarm output unit 30 sets the CPU in accordance with FIG. It is activated by the control unit 33. When the automatic lock mechanism is provided, the state is the same as the state where the door 24 is opened in the locked state, and the alarm output unit 30 is activated. On the other hand, in the sixth embodiment, C
The PU control unit 33 stores the state change of the medium storage device,
The configuration is such that the alarm output unit 30 is activated according to a change in the state of the medium storage device.

FIG. 11 is a diagram showing a start-up sequence of the alarm output unit 30 according to the sixth embodiment of the present invention. For example, as shown in FIG.
When the lock is unlocked and the door 24 is opened when the lock 4 is closed, the normal operation is continued when the destruction sensor 28a indicates normal, and when the destruction sensor 28a indicates abnormal The LED 35 emits light to indicate the failure of the destruction sensor 28a. Even when the door 24 is closed, the normal operation is continued when the destruction sensor 28a indicates normal, and when the destruction sensor 28a indicates abnormal, LE is used.
D35 emits light to indicate the failure of the destruction sensor 28a. In the past, when the lock is locked and the door 24 is closed, when the door 24 is suddenly opened or when the destruction sensor 28a indicates an abnormality, the alarm output unit 30 is activated.

As described above, in the sixth embodiment,
The CPU control unit 33 stores the state change of the medium storage device and activates the alarm output unit 30 according to the state change of the medium storage device. Therefore, the CPU control unit 33 can be equipped with an automatic lock mechanism. And security can be improved.

The present invention is not limited to the above embodiment, but can be variously modified. For example, there are the following modifications. (1) In the first to sixth embodiments, the medium storage device that is set in the automatic teller machine and stores banknotes has been described. Is also good. Further, the present invention can be applied to a case where the device is not set in another device such as a safe. (2) The destruction sensor 28a is not limited to a meandering conductive pattern as shown in FIG. 6, but may be a vibration sensor, for example.
