[Problems to be solved by the invention]
However, none of the above prior arts is a device for notifying the theft itself, but for preventing the occurrence of the theft, and operates under a predetermined condition when the cash register operator leaves the holding place. Therefore, even in a situation where theft has not occurred, an alarm will be issued in a situation close to theft, which will help prevent theft, but if the theft occurs It was not possible to distinguish between a notification that informs the user that there was a warning and a notification that notified other situations.
[0006]
In other words, in the former of the above prior arts, when the light of the light emitting element is incident on the phototransistor in a situation where the drawer is open, a sound is emitted, even if the monitoring by the operator is sufficient. However, when the operator instantly leaves the post, a sound is emitted. Further, when the operator does not leave the holding place, it does not function for the act of stealing the eyes of the operator and opening the drawer and extracting money from this, and even in the latter conventional technique, It did not function when the alert state was released. Further, if the cash register drawer is opened by an intruder on a holiday or at night, or the entire cash register is taken out by the intruder, no action can be taken.
[0007]
The present invention has been made in view of the above points, and has as its object to notify, during the opening hours, that money is stolen while the operator is distracted, It is an object of the present invention to provide an anti-theft device which can notify when opening a drawer or moving a cash register during a closed time such as a holiday or at night.
[0008]
[Means for Solving the Problems]
Therefore, the present invention provides a cash register including a cash storage unit and a register main body, wherein an alarm device main body installed in the cash storage unit, a vibration sensor built in the alarm device main body, and a connection to the vibration sensor. And a notification signal output means operated by the controller, and a notification means operated by a notification signal output from the notification signal output means. Is what you do.
[0009]
In this case, the alarm device main body may be mounted on the side surface of the frame constituting the money storage unit, mounted on the surface of the drawer, or mounted inside the drawer.
[0010]
In the above, the notification signal output means may include a notification sound generation circuit and an external output circuit, and may be configured to connect different types of notification means to the notification sound generation circuit and the external output circuit. Further, an alarm device that emits an alarm sound can be used as the alarm unit connected to the alarm sound generation circuit, and a transmitter that notifies an alarm state through a telephone line can be used as the alarm unit connected to the external output circuit. It can be.
[0011]
In addition, the controller is provided with a holding circuit that holds the state of the signal of the vibration sensor that has sensed the vibration, so that the alarm state can be notified even after the vibration is stopped. As the vibration sensor, a vibration sensor having a moving conductor that moves by vibration can be used. In this case, when the moving conductor moves, the vibration can be sensed by making the electrodes conductive. Further, a vibration sensor having a piezoelectric element can be used. In this case, the vibration can be sensed by the electromotive force generated when the piezoelectric element receives the distortion.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, as shown in FIG. 1, an alarm device 4 is installed in a drawer 3 of a cash storage unit 2 of a cash register 1, in which a vibration sensor and a vibration sensor are provided. A notifying means for issuing an alarm when detected is provided. The vibration sensor has a structure in which a spherical moving conductor is disposed between the electrodes, and the moving conductor that moves by vibration conducts between the electrodes.When the vibration sensor is operated, power can be supplied, and when the vibration sensor is not operated, By stopping the power supply, ON / OFF of the alarm device 4 can be operated. A battery is built in as a power supply necessary for supplying these powers. The alarm device main body constituting the outside of the alarm device 4 is provided with an adhesive means such as an adhesive, and includes a frame (not shown) which constitutes the cash storage unit 2 in addition to the surface of the drawer 3 of the cash register 1. (The part where the drawer 3 is stored).
[0013]
As shown in FIG. 2A, the alarm device 4 is configured so that a notification signal output unit 7 is activated by a signal output from a controller 6 connected to the vibration sensor 5. When an output signal generated from the vibration sensor 5 is input to the controller for more than a predetermined time, the controller 6 determines that the drawer 3 has been opened and activates the notification signal output means 7. The notification signal output means 7 is configured by a notification sound generation circuit 71, and the notification signal generation circuit 71 is connected to the notification means 8 configured by an amplification circuit 81 and an alarm device 82. The notification means 8 can output a notification sound generated by the notification sound generation circuit 71 from the alarm device 82. The notification signal output means 7 includes an external output circuit 72 different from the notification sound generation circuit 71. If an alarm lamp is connected to the external output circuit 72, the alarm signal is output from the controller 6. It is possible to turn on an alarm lamp by a signal, and if an automatic transmission device is connected, it is possible to transmit notification information through a telephone line by outputting the signal.
[0014]
Further, as shown in FIG. 2B, when the vibration sensor detects the vibration, the controller 6 recognizes the signal as an alarm state, and is provided with a holding circuit 61 for holding the alarm state. Even after a transition from a state where vibration is detected to a state where vibration is not detected, output of a signal to the notification signal output means 7 is continued as an alarm state until the holding circuit 61 is reset. The holding circuit 61 can be reset by stopping and re-supplying power by operating a switch of the power supply circuit. The power supply circuit is connected to a battery built in the alarm device 4 and does not use an external power supply. By providing an LED for indicating the remaining capacity of the built-in battery in the case of the alarm device 4, it is also possible to appropriately check the charging time or replacement time.
[0015]
Here, the cash storage unit 2 of the general cash register 1 has a configuration in which the drawer 3 is slidably moved and stored. A spring (not shown) for urging the drawer 3 in the opening direction is provided inside the money storage unit 2, and a not-shown lock for locking a part of the drawer 3 in a closed state is provided. A stop member is provided. Therefore, the drawer 3 can be stored by sliding the drawer 3 against the urging force of the spring, and the drawer 3 can be maintained in the stored state by the locking of the locking member. When the drawer 3 is opened, the lock by the locking member is released, and the drawer 3 slides by the bias of the spring. Note that a magnetic attachment method using a magnet is adopted as the locking member, and there is a mechanism for moving the magnet as a mechanism for releasing the magnetic attachment. The operation for releasing the locking of the locking member is performed by the ten keys 12 of the register main body 11. Further, on the opening side of the money storage unit 2 and the back side of the drawer 3, there is provided a stopping means that can be brought into contact with each other. Position).
[0016]
The opening of the drawer 3 is caused by the slide by the urging of the spring after the lock by the locking member is released, so that a time loss occurs until the drawer 3 is completely opened. In addition, the speed of the drawer 3 stopped in the retracted state immediately after the slide is started is very low, but the drawer 3 that slides is forcibly stopped at a predetermined open position after increasing the acceleration. It is made to do.
[0017]
In the present embodiment, as described above, the alarm device 4 is installed in the drawer 3 of the cash storage unit 2 in the cash register 1. This has the above-described structural features of the cash register 1. To make the most of it. That is, as shown in FIG. 1, when the alarm device 4 is installed in the drawer 3 of the money storage unit 2, the drawer 3 starts to slide, and the alarm device 4 attached to the drawer 3 and the inside thereof are displayed. While the main body portion of the vibration sensor 5 provided moves together with the drawer 3, the moving conductor built in the vibration sensor 5 moves backward inside the vibration sensor 5 by inertia force. . Due to the movement of the moving conductor, the electrodes inside the vibration sensor are electrically connected, the vibration sensor senses the vibration, and the notification means 8 operates before the drawer 3 is fully opened.
[0018]
Furthermore, as described above, since the drawer 3 is forcibly stopped after increasing the acceleration by the urging force of the spring, it receives a large impact. Therefore, even if the moving conductor of the vibration sensor 5 immediately after the opening of the drawer 3 does not move sufficiently and the vibration sensor 5 cannot detect the vibration, the vibration sensor 5 is stopped again by the impact when the slide of the drawer 3 stops. Is given an opportunity to detect vibration. In addition, even if this kind of impact is mitigated and the vibration sensor 5 does not detect the shock, the open drawer 3 is in an unstable state in which only one side is supported, so that the money is stolen. By touching the drawer 3 at the same time, the drawer 3 easily vibrates, and this vibration gives an opportunity for sensing by the three-time vibration sensor 5.
[0019]
As described above, since the alarm device 4 is attached to the drawer 3, it is possible to obtain the opportunity to detect vibration many times. When a signal indicating vibration is transmitted, the vibration state is maintained, so that the notification means operates continuously, and it is possible to report the unauthorized opening and stealing of the drawer 3. is there.
[0020]
Further, when the alarm device 4 is mounted on the side surface of the frame constituting the money storage unit 2, in order to open the drawer 3, it is necessary to release the locking by the above-described locking member. Since the operation for releasing the locking member is performed on the inner wall surface of the money storage unit 2, the notifying means 8 can be operated by sensing the vibration generated at this time. Further, as in the case where the alarm device 4 is attached to the drawer 3, vibration occurs when the slide of the drawer 3 stops and when money is taken out from the inside of the drawer 3. The opportunity to sense is given three times.
[0021]
The vibration transmitted to the alarm device 4 is expected to be different between the case where the alarm device 4 is mounted on the frame of the money storage unit 2 and the case where the alarm device 4 is provided on the drawer 3. Therefore, in the alarm device of the present embodiment, the operating conditions of the notification means and the like can be adjusted according to the time when the signal output from the vibration sensor 5 is input to the controller 6. That is, when the alarm device 4 is installed in the frame of the money storage unit 2, it is determined that the drawer 3 is opened in a state where the signal input time from the vibration sensor 5 is relatively short, and the alarm device 4 is installed in the drawer 3. In this case, it is determined that the drawer 3 has been opened when the signal input time from the vibration sensor 5 is relatively long.
[0022]
Since the present embodiment is configured as described above, when an operator is present near the cash register 1 and the alarm device 4 is activated, for example, when the operator distracts the attention from the cash register 1, When the thief tries to steal cash stored in the cash register, the thief must open the drawer 3 by operating the numeric keypad 12 or the like. However, the state of the drawer 3 which has started sliding for opening is sensed by the vibration sensor 5. If the notification by the notification means 8 is started based on the signal from the vibration sensor 5, even if the drawer 3 can be opened, it is difficult to steal cash.
[0023]
In addition, when the drawer 3 moves, the vibration sensor 5 senses the movement, and the notification sound or other notification by the notification means 8 allows the operator to know that the drawer 3 is open. Becomes possible. In addition, when the drawer 3 starts operating at the same time as the slide starts, the notification means 8 emits a notification sound or the like before the drawer 3 is still completely open, and the notification sound or the like attempts to steal. Even if the drawer 3 is opened, it can be expected that the thief will give up stealing the money even if the drawer 3 is opened.
[0024]
Also, at night, when the intruding thief opens the drawer 3, it is natural that the notification means 8 is activated, and the notification connected to the external output circuit 72 simultaneously with the operation of the notification means 8. By means, it is possible to notify the owner, the police company or the police station in charge. Further, depending on the intruder, the cash register 1 may be stolen without opening the drawer 3 at the place where the cash register 1 is installed. However, in order to move the cash register 1, the cash storage unit is required. The drawers 3 accommodated in the storage 2 are simultaneously moved. Even in such a case, the vibration sensor 5 is vibrated, and the notification means 8 and the like are activated. In this case, when the entire cash register 1 is stolen, the cable for supplying power to the cash register 1 is pulled out from the outlet. The prevention device 4 has a configuration in which a battery is incorporated.
[0025]
Further, the present embodiment is not limited to a defense device against an intruder or the like from the outside, but can be used to defend against embezzlement inside. That is, when many persons use the same cash register, even if the cash stored in the cash storage unit is lost, it is not clear whether the cause is theft, change fraud, or embezzlement. By using the anti-theft device 4 of this embodiment, in addition to the theft prevention, embezzlement can also be prevented. In this configuration, one anti-theft device 4 is assigned to one operator for a plurality of operators, and the switch operation of these devices 4 can be operated with different keys. Even if the cash register 1 is the same, since the alarm device 4 installed in the drawer 3 is different, if an inside person operates the cash register 1 outside the time in charge of the operator, the alarm device 4 is activated. That would be. By using such a device, even if the alarm device 4 is not activated, the insider can hesitate to embezzle, so that a crime can be prevented beforehand. Becomes possible.
[0026]
Although the present embodiment is as described above, various modes can be adopted without departing from the spirit of the present invention. For example, as the vibration sensor 5, various types of vibration sensors can be considered. In addition to the configuration in which the moving conductor in the above-described embodiment is turned on to make it conductive and a signal is generated by this conduction, a vibration sensor using a piezoelectric element is used. It is possible to do. As is well known, a piezoelectric element generates an electromotive force when it receives a strain.Therefore, a weight that applies a strain to the piezoelectric element is provided, and an inertial force or the like is applied to the weight to cause the piezoelectric element to generate an electromotive force. A vibration sensor configured to generate the vibration can be used. This type of vibration sensor can also detect the inertial force due to the start of sliding of the drawer 3 in the above-described embodiment, so that the same effect as in the above-described embodiment can be obtained.
[0027]
Further, the alarm device 4 in the above embodiment is configured to switch between the operating state and the release thereof depending on the presence or absence of power supply from the power supply circuit. However, the switching can also be performed by conducting and disconnecting other circuits. It is possible. These switches can be easily operated by providing a switch on the main body of the alarm device 4. If the switch is operated using a key possessed by an operator, the switch can be operated by other operators. The user cannot stop the operation of the notification means 8. Further, in addition to the method of performing the switch operation mechanically, it is also possible to adopt a configuration in which the switch operation is performed wirelessly. In this case, it is possible to simplify the labor of the switch operation by the operator.
[0028]
Further, it is also possible to adopt a configuration in which the alarm device 4 of the above embodiment is mounted inside the drawer 3. In this case, it is necessary to provide a time lag from when the switch for activating the alarm device 4 is turned on to when the device actually operates. That is, since the drawer 3 is closed after the alarm device 4 installed inside the drawer 3 is operated, the vibration caused by the closing is detected by the vibration sensor 5 and the notification means 8 is prevented from operating. It is. To be precise, even if the alarm device 4 is installed on the side surface of the money storage unit 2 or on the surface of the drawer 3, it is configured not to operate for several seconds after the device is turned on. is there. This is to prevent the alarm device 4 from being activated by the vibration generated by the switch operation.
[0029]
The configuration in which the alarm device 4 is installed inside the drawer 3 as described above is used exclusively for a store where people are unmanned, such as at night or on holidays, or for theft prevention when the cash register 1 is not used for a long time. That is, when the cash register 1 is frequently used during business hours, a dedicated operator is often in charge of only operating the cash register, the possibility of theft being extremely low, and setting of the alarm device. This is because the release is laborious, so that the theft only needs to be prevented during the night or on holidays when the dedicated operator does not operate the cash register. In the case where the alarm device 4 is provided inside the drawer 3, since the installation of the alarm device 4 cannot be seen from outside the cash register, when an insider other than the operator in charge attempts to embezzle the alarm device 4, Because he does not notice the existence of such a crime, such a crime can be found.
[0030]
【The invention's effect】
As described above, according to the present invention, in a situation where the operator does not operate the cash register, the alarm device is activated, whereby the vibration of the drawer caused by opening the drawer is sensed, and the illegal opening of the drawer is detected. Can be informed. This notification means that at least a person other than the operator in charge of operating the cash register has opened the drawer, so that it clearly responds to a suspicious activity, so that notification irrelevant to the theft may be made. Absent. Further, not only the intruder from outside but also other operators and related persons can activate the notification means by opening the illegal drawer, so that embezzlement by an inside related person can be suppressed.
[0031]
Further, even in an unmanned state such as a holiday or nighttime, the opening of the drawer or the movement of the cash register body activates the notification means, which contributes to the prevention of theft outside business hours.
