It is characterized by comprising warning means for giving a warning (for example, warning means 26 in the embodiment).

  According to the first aspect of the present invention, when an event that requires a key occurs in a cash machine, the key management information is used as a key take-out request signal from the cash machine as a key take-out request signal. The key management machine that outputs to the machine and receives the key take-out request signal determines the storage location of the key necessary for handling the event by the recognition means, and responds to the event stored in the determined storage location. By using the output means to output the necessary keys to be taken out from the storage location, the user, for example, the person in charge or the administrator, takes out the keys necessary for handling the event from the correct storage location according to the output output from the output means. Therefore, it is possible to prevent the wrong key from being taken out and to reliably perform the action for the event request.

  According to the second aspect of the present invention, when an event that requires a key occurs in a cash processing machine, key storage location information necessary for handling the event from the cash processing machine is used as a key take-out request signal for key management. In the key management machine to which the key take-out request signal is input, the output means outputs the instruction for taking out the key necessary for handling the event based on the storage place information. For example, the person in charge or the administrator can take out the key necessary for handling the event from the correct storage location according to the instruction output of the output means. All the treatments can be performed reliably.

For example, when a person or administrator who is not in charge of taking out the key logs in with a request that has nothing to do with the event request, the functions of the output means and lock control means are prevented from working. Therefore, there is an effect that it is possible to prevent a person in charge or a manager who is not in charge of taking out a key from taking out a key necessary for handling an event.

  According to the sixth aspect of the invention, in addition to the effect of the fourth aspect, the output unit is necessary for handling an event when, for example, outputting an instruction related to taking out a key necessary for handling the event. When a person in charge of taking out a key other than a valid key or an administrator logs in using the login means, the output means regulates the instruction output so that only keys other than those necessary for handling events can be taken out. Or, after the administrator logs out, the restriction on the instruction output can be released again, and the instruction output to the person in charge of taking out the key required for handling the event or the administrator can be performed. Hide the instruction output when taking out the key from the person in charge of taking out other keys other than the key required for handling the event or the administrator, and lock out the key required for handling the event. It can be inhibited by the control means. Therefore, it is possible to more surely prevent a key necessary for handling an event from being erroneously taken while allowing another key take-out person or administrator to take out another key.

  According to the seventh aspect of the present invention, in addition to the effect of any one of the first to sixth aspects, the second output means allows the key take-out person to have the access right. Key take-out instructions can be output via an information terminal such as a general-purpose console or a general-purpose PC or portable terminal. After taking out the key necessary for handling the event with the key management machine, it is possible to go to the cash processing machine where the event occurred. Therefore, after confirming the occurrence of an event with a cash machine, the key management machine takes out the key necessary for handling the event and then goes back to the cash machine to reduce the time required to start treatment. There is an effect that can.

  According to the eighth aspect of the present invention, in addition to the effect of the seventh aspect, after the processing of the event generated in the cash processing machine using the key necessary for handling the event is completed, the key is used as the key management machine. If the key is not returned after a certain period of time, a key return request signal can be sent to the information terminal of the person who took the key or the administrator. Therefore, it is possible to prevent the key from being forgotten and lost.

  According to the invention described in claim 9, in addition to the effect of claim 8, the time information from when the key take-out request signal is input to when the key treatment completion signal is input is stored in the storage means. The downtime of the processor can be centrally managed by the key manager.

  According to the invention described in claim 10, in addition to the effect of any one of claims 1 to 9, the key management machine does not recognize the key take-out request signal, for example, a business in which no event has occurred in the cash processing machine Event code from the input means when loading cash before starting, withdrawing cash cassettes after work completion, maintenance inspection, etc., or when the communication line between the cash processing machine and key management machine is bad Since the key corresponding to the event code can be taken out by inputting, there is an effect that the key can be strictly managed when no event occurs in the key manager.

  According to the eleventh aspect of the invention, in addition to the effect of any one of the first to tenth aspects, the event information of the cash processing machine that requires the key takeout is output in addition to the key takeout request signal. Thus, for example, when the output history of the event information and the key take-out request signal is left, it is possible to easily grasp the type of event relating to the key take-out and the take-out time.

  According to the invention described in claim 12, in addition to the effect of any one of claims 1 to 11, even if a predetermined time elapses after the key of the key management machine is taken out, the response action of the event in the cash processing machine is When it is not performed, a warning can be given by warning means to prevent unauthorized use such as key duplication.

A display unit 16 for displaying date and time, operation status, alarm information, guidance, and the like, and an ID card 17 prepared for each person in charge and storing individual person identification information for identification with others A card reader 18 that scans and reads person-in-charge identification information from the ID card 17, a number (1 to 18) of key holders 19 that hold the corresponding keys 10 in a one-to-one manner, and are necessary. 1, a control unit 21 shown in FIG. 1 connected thereto, a storage unit 22 capable of exchanging data with the control unit 21, a second output unit 23, Multiple key holders 19 Provided, a locking mechanism 24 for locking and releasing the removable key 10 to each of the key holding unit 19, and a speaker 25, and a warning means 26.

  The key 10 (see FIG. 2) has a key body 33 and a key holder 34 connected thereto, and the key holder 34 stores individual key identification information for identifying the key 10 from others. An ID chip (not shown) is embedded.

  The key holding unit 19 of the key management machine 11 is the same key holding unit 19 as the key holder mounting unit 30 that holds only the key holder 34 of one key 10 that corresponds one-to-one in a locked state by the respective locking mechanism 24. The key holder mounting portion 30 that constitutes the key holder mounting portion 30 has a removal button 31 that is pressed when the lock state is released, and a lamp 32 that can be turned on and blinked. When the key holder 34 is inserted, the key holder mounting unit 30 reads the key identification information and transmits it to the control unit 21. The control unit 21 corresponds to the case where the key identification information corresponds to the source key holder mounting unit 30. The key holder 34 is locked by the lock mechanism 24 of the key holder mounting portion 30. Moreover, the key holder mounting part 30 will release the lock | rock by the lock mechanism 24, if the removal button 31 is operated on the conditions which the control part 21 approved. In this way, the required key 10 can be attached and detached when taking out and returning.

  The key 10 is mainly configured and used with a cash machine 12 such as a counter machine, a sorting machine, a cashier, a money changer, and an ATM. The types of the keys 10 are roughly classified into three types: device keys (also called door keys), clerk keys (or manager keys), and cash keys (or officer keys). The usage rights according to the responsibilities of the person using 10 are ranked.

Here, the above-mentioned “device key” is a key 10 for unlocking the device door of the cash processing machine 12 and accessing a unit in the device, and generally operates the cash processing device 12. The key 10 that the person in charge has the right to use.
The “clerk key” is an operation of a rank with higher responsibility than the rank that is normally operated by the above-mentioned person in charge, for example, the operation mode of the cash processor 12 is changed to the administrator mode, and cash as transaction funds is funded. It is a key 10 used when performing operations such as replenishment and collection as a remuneration process with the original principal, and operations for changing the function settings and operation settings of the cash processing machine 12 main body, In general, the key 10 has a right to use by an intermediate manager (for example, a chief officer).
The “cash key” is a key 10 for unlocking a cash cassette door or the like in the cash processing machine 12 and accessing the cash stored therein. It is a key 10 that is used by a senior manager called. The higher-level person has the right to use the key 10 held by the lower-level person. More specifically, the intermediate administrator has the right to use the device key that the person in charge has the right to use. The administrator has the right to use the staff key that the intermediate manager has the right to use and the device key that the person in charge has the right to use.

  The storage unit 22 stores take-out return status data and the like related to take-out and return of the key 10. The storage unit 22 stores key identification information of the keys 10 held in a one-to-one correspondence with all the key holding units 19 and personal identification information that is ID information of all the ID cards 17 that can be handled. Further, key identification information of the key 10 that can be taken out by being ranked for each ID information is stored. Here, when ranking is performed, for example, as described above, according to the right to use the key 10, it is divided into a person in charge and a manager (for example, intermediate manager, senior manager, etc.) and can be taken out for each rank. The key identification information of the key 10 is stored in association with each other. Further, when the key 10 that can be taken out is different for each person in charge and manager even if they are of the same rank, key identification information that can be taken out is stored in association with each ID information of the person in charge or manager. . That is, by configuring the storage unit 22 as described above, the key management machine 11 can determine the specific key 10 corresponding to the ID information of a specific person in charge or the manager, The ID information of the person in charge or the manager corresponding to the key 10 can be determined.

  Further, the storage unit 22 stores setting information of a function for communicating with a plurality of cash processors 12, that is, a function for communicating with the cash processor 12 via the LAN 13. Since this communication function may be different for each of the plurality of cash processors 12, the setting information of the dedicated communication function is stored in the storage unit 22 of the plurality of key management machines 11. Here, as the setting of the communication function, for example, all the key management machines 11 can be set to be connected to a plurality of cash processing machines 12 via the LAN 13 and communicated individually, and one master serving as a master can be set. Only the key manager 11 is connected to the plurality of cash processors 12 via the LAN 13, and the other plurality of key managers 11 are set to be connected as slave coupling subordinate to the one key manager 11 serving as the master. it can.

  The display unit 16 includes a display screen 16a such as a liquid crystal and a touch panel 16b provided on the display screen. The display screen 16a can display guidance for operating the key management machine 11, taking out the key 10, information on the key 10, and the like based on a control command from the control unit 21. The touch panel 16b detects that the user has pressed the selection button when a selection button or the like is displayed on the display screen 16a.

The card reader 18 is for reading personal identification information recorded in the ID card 17 by scanning the ID card 17 distributed in advance to the person in charge or the administrator. By reading the personal identification information, the owner of the ID card 17 can be authenticated.
Following the reading operation of the personal identification information by the card reader 18, the operation unit 15 inputs a password set for permission to take out the key 10, or for example, a key take-out request to be described later to the key manager 11. It is composed of a keyboard or the like for inputting a predetermined event code when the signal does not reach. In addition, although it demonstrated that both the operation part 15 and the touchscreen 16b of the display part 16 were provided, it is not restricted to this, You may make it provide either one input means.

  The printer unit 20 prints out the content displayed on the display screen 16a of the display unit 16, and is controlled by the control unit 21 based on, for example, an operation input on the touch panel 16b.

  The second output means 23 stores the key 10 for a specific PC or portable terminal for which the person in charge of taking out the key 10 has access right, or for a specific PC or portable terminal for which the administrator has access right. A key return request signal including a data signal including location information and a message for prompting the return of the key 10 is transmitted.

The lock mechanism 24 is a mechanism that locks / unlocks the attachment / detachment of the key holder 34 in a state in which the key holder 34 is inserted into the key holder mounting portion 30, and the operation of the lock mechanism 24 is controlled by the lock control means 21c.
The speaker 25 outputs sound for guiding the key 10 to be taken out, and its operation is controlled by the control unit 21.
The warning unit 26 uses the speaker 25, the display unit 16, the second output unit 23, and the like to output a voice message or message when the control unit 21 determines that a warning is required for the person in charge or the administrator. A warning is given by display.

The control unit 21 includes a recognition unit 21a, a login unit 21b, and a lock control unit 21c.
When the key take-out request signal is input, the recognizing unit 21a determines a storage location of the key 10 necessary for handling an event based on the key identification information included in the key take-out request signal. More specifically, the storage location information stored in association with the key identification information that matches the key identification information included in the key take-out request signal by searching the storage information in the storage unit 22 is specified.

  When the card reader 18 scans the ID card 17 and a password is input by the operation unit 15, the login unit 21b stores the personal identification information of the read ID card 17 and the input password. When the personal identification information and the personal identification number are appropriate, the log-in is determined to be normal. Here, when the login unit 21b determines that the login is normal, the control unit 21 has the lamp 32 of the key holding unit 19 that holds the key 10 having the key identification information set to be able to be taken out with respect to the personal identification information. Control to turn on is performed. Note that biometric authentication such as fingerprint authentication or palm vein authentication may be combined in place of the input of the personal identification number by the operation means. Also, any configuration is acceptable as long as the individual authentication check functions, and the authentication method is not limited.

  The lock control means 21c controls the operation of the lock mechanism 24. When the person in charge or the administrator who is determined to be logged in normally operates the detach button 31 of the key holding unit 19 whose lamp 32 is lit, The key 10 can be removed by releasing the lock state of the key holder mounting portion 30 of the key holding portion 19. Thus, by releasing the locked state of the key holder mounting portion 30, the key holder 34 of the key 10 can be removed from the key holder mounting portion 30 corresponding to the removal button 31. As a matter of course, even when the removal button 31 of the key holding unit 19 other than the part where the lamp 32 is lit is operated, the control unit 21 releases the locked state of the key holder mounting unit 30 of the key holding unit 19. It is set not to.

  The control unit 21 further reads the ID information of the ID card 17 read when the key 10 is taken out, the key identification information of the taken out key 10, the take-out time (or date and time) when the removal button 31 is pressed, and the key 10 The storage unit 22 stores take-out return status data including information that is being taken out and indicating the return time or return date and time (which is blank when not returned).

  When the person in charge or the manager returns the key 10 and the key holder 34 of the key 10 is inserted into the key holder mounting portion 30 of one key holding portion 19 corresponding one-to-one, the control unit 21 returns to the key holder. The key identification information is read from 34, and it is determined whether or not the key identification information corresponds to the key holding unit 19 on a one-to-one basis. If the key identification information corresponds to the key holding unit 19, the lock control means 21c performs lock control so that the attached key 10 cannot be taken out, and the key 10 cannot be taken out.

  Further, when the key 10 is returned, the control unit 21 takes out that the key 10 is being taken out in the latest take-out return status data stored in the storage unit 22 and associated with the key identification information. The medium information is rewritten to the holding information indicating that the key 10 has been returned, and further, the locked time is set to the return time (or date and time) that was left blank. On the other hand, if the key identification information read from the key holder 34 does not correspond to the returned key holding unit 19, the control unit 21 does not lock the key holder 34 and makes an error by blinking the lamp 32 or the like. Control to notify is performed. Note that when the key 10 is returned, the key 10 may be locked by the key holder mounting unit 30 on condition that the appropriate ID card 17 is scanned by the card reader 18.

  In addition, the control unit 21 is set to update the carry-out return status data regarding the take-out and return of the key 10 to the latest data whenever the key 10 is taken-out and returned, and the carry-out return status data is updated. At that time, the history before the update is added each time so that the past use history before the update can be referred to, and the history is recorded.

  For example, when an event code set in advance for each predetermined event is input by the operation unit 15 when the key takeout request signal cannot be received due to, for example, a communication system trouble or the like, The same control as when a key take-out request signal is input is performed. The event code is stored in the storage unit 22 in advance, and key identification information of the key 10 necessary for handling an event is associated with each event code.

  As an example of the event code input by the operation unit 15, for example, any two-digit number from 00 to 99 can be used. More specifically, the event code for loading the cash into the cash cassette before the start of business is set to “01”, and the cash that was temporarily stored in the vault with the cash carried forward from the previous night The event code of the event that resets the cassette in the cash processing machine 12 before the start of business is set to “02”, and the cash remains in the cash for the purpose of storing it in the vault after carrying out the business. The event code of the event for taking out the cassette from the cash processor 12 is set to “03”, and the event code of the maintenance check work event of the cash processor 12 by the maintenance staff of the manufacturer of the cash processor 12 unrelated to the transaction is “10” is set. The event code is not limited to that described above, and any event code may be used as long as the event type can be identified.

  Further, the control unit 21 stores the time when the key 10 was taken out in the storage unit 22 and activates timer monitoring for a predetermined time in the control unit 21 so that the key 10 is used after the key 10 is taken out. When the timer monitoring times out after a predetermined time has passed without the key processing start signal indicating that the event processing has been started being input to the key manager 11, the warning means 26 issues a warning. Is set. The fact that the key treatment start signal is not input to the key management machine 11 even though the key 10 has been taken out in this way may be used for the purpose of unauthorized use, for example, duplication of the key 10. It is set to warn this.

  The plurality of cash processing machines 12 includes an operation unit 35 that is input by an operator, a display unit 36 that displays operation status, alarm information, guidance, and the like, a cash processing mechanism unit 38 that performs cash processing, And a control unit 37 connected to each other. The control units 37 of the plurality of cash processing machines 12 are used by being connected to the in-store server 40 installed in the store by the LAN 13, and further, the unillustrated headquarters installed in the headquarters of a financial institution outside the store. It is connected to the server and controls cash processing.

  In addition, as with the storage unit 22 of the key management machine 11 described above, the plurality of cash processing machines 12 are set with a communication function via the LAN 13 with the plurality of key management machines 11. In the storage section (not shown), communication function setting information dedicated to the cash processor 12 is stored in advance. The storage unit of the plurality of cash processing machines 12 stores communication settings with a plurality of key management machines 11 that are communication partners, and what kind of event occurs with respect to the various keys 10 used by the cash processing machine 12 itself. Which key 10 is required at the time of occurrence is stored in association with each other.

Next, notification of an event that requires the key 10 from the cash processing machine 12 to the key management machine 11 will be described.
When an event that requires a specific key 10 occurs during cash processing transactions such as depositing, withdrawing, and changing money individually, the plurality of cash processing machines 12 are keys of the key 10 that are necessary for handling the event. The identification information is transmitted as data to the key manager 11 via the LAN 13 as a key take-out request signal, and information is transmitted. Here, the above-mentioned “key identification information” is identification information inherently possessed by the key 10, for example, information composed of numbers and the like. As this key identification information, for example, a coded number such as a number assigned from the beginning in the manufacturing process of the key 10 can be used. Key identification information such as “KAXXX” and “KBXXX” is allocated to the cash key. When there is a key 10 that is not assigned a number, a specific code (for example, a three-digit decimal code) can be newly assigned. Further, not only the keys 10 that are not numbered but also a specific code (for example, a three-digit decimal code) is newly assigned to all the keys 10 including the key 10 that is numbered. May be.

  Here, as an event that requires the key 10 described above, for example, there is a full safe event that occurs during a deposit transaction at a counter. In the event of a full box safe, if the cash machine 12 is accessed using the device key and the cash key, the cash in the bulk safe is not withdrawn and the collective safe full state is not canceled, and subsequent deposits are made. There is a risk that transactions cannot be made. As another event, for example, there is an event in which the reject storage is full during a withdrawal transaction at a counter. This storage full event can only be used for subsequent withdrawal transactions unless the cash machine is used to access the counter to remove the cash in the reject storage and release the full state of the reject storage. There is. Furthermore, there is an event in which a cash stacker of a specific denomination becomes empty during a withdrawal transaction at a counter. In the event that the cash stacker is empty, there is a possibility that subsequent withdrawal transactions cannot be performed unless the cashier is replenished by accessing the counter using the attendant key and replenishing the cash stacker. In addition, there is a device abnormality event such as jam or mechanical lock during any transaction. When this event occurs, there is a possibility that no further transaction can be performed unless the counter is accessed using the device key and the device abnormality recovery process is not performed.

  In addition to the above-mentioned teller machine, various events also occur for the cashier machine 12 such as a cash machine, a money changer, and an ATM. As a measure for this event, a specific key 10 is used to deal with the cash machine 12. There is a case where it is necessary to access, and it is an event that requires the key 10 as in the case of the window machine described above. That is, the cash processing machine 12 has a mechanism in which one or more necessary keys 10 are required for each cash processing machine 12 and each event that occurs.

  The key management system 1 according to this embodiment has the above-described configuration. Next, the operation of the key management system 1 will be described. In the following description, among the plurality of key management machines 11 from No. 1 to No. n, the device key attached to the No. 1 key holder mounting part 30 of the No. 1 key holding part 19 and the No. 1 machine An event that requires a cash key attached to the No. 13 key holder attaching part 30 of the key holding part 19 of the key management machine 11 occurs in the teller machine that is the cash processing machine 12, and the above-mentioned necessary for handling this event. The case where the device key and the cash key are taken out from the key holding unit 19 of the first key management machine 11 and returned to the key holding unit 19 will be described as an example.

First, in a teller machine (hereinafter simply referred to as a cash processing machine 12), a key 10 (hereinafter referred to as a device key) attached to the first key holder attaching part 30 of the key holding part 19 of the key management machine 11 of the first machine. And an event that requires a key 10 (hereinafter simply referred to as a No. 13 key 10) that is a cash key mounted on the No. 13 key holder mounting portion 30. When it occurs, the control unit 37 of the cash processing machine 12 transmits a key take-out request signal including the key identification information of the first key 10 and the 13th key 10 to the plurality of key management machines 11.
When receiving the key takeout request signal output from the cash processing machine 12, the control unit 21 of the first key management machine 11 recognizes the key identification information included in the key takeout request signal by the recognition means 21a, and recognizes this recognition. The key identification information thus identified is identified as the key identification information that matches the key identification information of the key 10 mounted on the key holder mounting unit 30 of the key holding unit 19.

  Based on the identified key identification information, the recognizing means 21a of the control unit 21 uses the first key 10 (device key) mounted on the first key holder mounting unit 30 of the key holding unit 19 of the key management unit 11 of the first unit. ) And the thirteenth key 10 (cash key) mounted on the thirteenth key holder mounting portion 30 is recognized as the corresponding key 10.

  After that, the person in charge of taking out the key 10 necessary for handling the event or the administrator passes the ID card 17 through the card reader 18 relative to the key management machine 11 and sets the key 10 to be allowed to be taken out from the operation unit 15. When the entered personal identification number is input, the log-in means 21 b of the control unit 21 authenticates the owner of the ID card 17. When it is determined that the owner of the ID card 17 is a regular owner, the login unit 21b of the control unit 21 determines that the login is normal and sets the login state. Here, the login state means that the person in charge or the administrator of the key 10 that has a take-out request is in the state before the user has logged in, the state in which the user has taken out the key 10 after logging in, and the user has logged out. The state where the process was canceled for some reason and logged out, or the person in charge or the administrator logged in and took out the necessary key 10 and logged out again for the purpose of returning the key 10, etc. Not included.

  In the login state, the control unit 21 outputs guidance for taking out the first key 10 and the thirteenth key 10 to the display unit 16, the printer unit 20, and the speaker 25 as output means as an instruction output for taking out the key 10. Output. Here, the guidance for taking out the key 10 is the number of the key holder mounting portion 30 of the key 10 necessary for handling the event. For example, in the case of No. 1 and No. 13, “No. 1 and No. 13 keys are taken out. A message such as “Please” is displayed on the display screen 16 a of the display unit 16. In addition, although the case where the guidance for taking out the key 10 was performed when it was found that the owner of the ID card 17 was a regular owner, the person in charge of taking out the key 10 necessary for handling the event or the administrator is 1 The person in charge of taking out the key 10 necessary for handling the event or the administrator may confirm the guidance on the display unit 16 at a point opposite to the key management machine 11 of the machine. In this case, the guidance start timing is that the key manager 11 of the first machine receives the key take-out request signal from the cash processor 12, and then the person in charge of taking out the key 10 necessary for handling the event or the administrator What is necessary is just to be a time point when a predetermined time required to walk to the key management machine 11 and face each other has passed. Also, with regard to the end timing of the guidance, the guidance is ended when it is detected that the key 10 necessary for handling the event is removed from the key holder mounting portion 30 of the key management machine 11 of the first machine and taken out. It ’s fine. Further, the function for outputting the guidance may be restricted based on the login result by the login unit 21b, that is, the authority of the logged-in person.

  When a person in charge of taking out the key 10 necessary for handling an event or an administrator sequentially operates the detach button 31 of the first key holder mounting portion 30 and the detach button 31 of the thirteen key holder mounting portion 30 according to the above-described guidance, the control is performed. The part 21 releases the lock mechanism 24 of the number 1 key holder mounting part 30 and the lock mechanism 24 of the number 13 key holder mounting part 30 to make the number 1 key 10 and number 13 key 10 detachable. . At this time, the lock mechanism 24 of the key holding unit 19 that holds other keys 10 that are not required to be taken out is locked by the lock control means 21c even if the key 10 that can be taken out by the person in charge or the administrator right is held. Release control is not performed.

  When receiving the key take-out request signal from the cash processing machine 12, the control unit 21 of the key management machine 11 obtains the received time with reference to a clock (not shown) built in the key management machine 11. Then, this time is used as a log of the time when the event requiring the key 10 is generated in the cash processor 12 and the take-out of the key 10 necessary for handling this event is requested (this time is referred to as time A). The data is automatically stored in the storage unit 22.

  On the other hand, the person in charge of taking out the key 10 necessary for handling the event or the administrator takes out the first key 10 and the thirteenth key 10 from the key management machine 11, and the event that occurred in the cash processing machine 12 When the handling process is completed, the control unit 37 of the cash machine 12 transmits a key process completion signal indicating that the key process has been completed to the key management machine 11. When the key management machine 11 receives the key action completion signal, it determines that the event handling process has been completed, and the time at which the event handling process using the first key 10 and the 13th key 10 taken out has been completed. (This time is called time B) is obtained with reference to a built-in clock, and this time B is automatically stored in the storage unit 22 as a log.

  When the time A and the time B are obtained, the control unit 21 of the key management machine 11 calculates an elapsed time (hour minute second) between the time A and the time B. This calculation result is separately stored for each of the plurality of cash processing machines 12 and stored in the storage unit 22 as a log during a unique tabulation process in the key management machine 11. In the key management machine 11, the elapsed time (hour / minute / second) from the time A to the time B is set as an accurate pause time for each cash processing machine 12 and for each occurrence of an event that requires the key 10. It can be recorded, and the total number of events that occur on a daily or monthly basis can be calculated to calculate the total suspension time, allowing easy analysis of the suspension time for each cash processor 12 It becomes.

  Further, the key management machine 11 keeps the first key 10 and the 13th key 10 taken out even if a predetermined time has elapsed from the time B when the key processing completion signal is received from the cash processing machine 12. In the case where it is not returned to the predetermined key holder mounting portion 30, the second output means 23 causes the specific person or the portable terminal that the person in charge of taking out the key 10 has the access right, or the administrator owns the access right. A key return request signal including a message “return keys No. 1 and No. 13 of No. 1 key management machine” is transmitted to a specific PC or portable terminal. Here, the key return request signal is automatically distributed to the person in charge of taking out the key 10 or the administrator by e-mail or the like. The predetermined time from the time B is appropriately set by the administrator according to the device layout (operation status) such as the distance from the key management device 11 for each cash processing machine 12 and stored in the storage unit 22 in advance. It's time.

  On the other hand, when an event handling procedure is started by the key 10 taken out, the control unit 37 of the cash processing machine 12 transmits the start information to the key management device 11 as a key processing start signal. The transmission of the key treatment start signal is triggered by, for example, access to the cash processor 12 using the key 10 first, even when a plurality of keys 10 are taken out. For example, the first key 10 (device key) and the thirteenth key 10 (cash key) are taken out, and the door of the cash processing machine 12 is accessed using the first key 10 which is the device key. When the cash stacker unit is opened and the cash stacker unit is pulled out and then the cash stacker is accessed with the key No. 13, which is a cash key, the cash processor 12 is first accessed with the device key. A key treatment start signal is transmitted at the timing.

  The control unit 21 of the key manager 11 issues a warning by the warning means 26 when a predetermined time elapses without recognizing the key treatment start signal after the key 10 is taken out and the timer monitoring times out. Do. As for the warning by the warning means 26, a warning message may be displayed on the display unit 16 of the main body of the key management machine 11, or a large display unit of another unit provided as an option near the key management machine 11 is used. The warning message may be displayed in a large character display. Similarly, a separate voice guide unit may be provided as an option to output a warning message by voice. Further, the above-described second output means 23 may output a warning message to a predetermined senior manager's PC or portable terminal by e-mail or the like.

  On the other hand, when the key take-out request signal is not input in the key manager 11 and a predetermined event code is input from the operation unit 15, the control unit 21 stores an event code that matches the event code in the storage information in the storage unit 22. Search from. If there is an event code that matches the event code input by the operation unit 15, the key identification information stored in association with this event code is specified, and for example, the key take-out request signal described above can be received. In the same manner as described above, the key 10 necessary for handling the event is allowed to be taken out and other keys 10 are restricted from being taken out. That is, when any key 10 is taken out, the lock mechanism is not released unless the key take-out request signal is input or the event code is input from the operation unit 15, and the key 10 is not allowed to be taken out. . Also, even if an incorrect event code is input, the key 10 is not allowed to be taken out.

The control unit 21 of the key management machine 11 adds the event code as a condition for permitting the key 10 to be taken out by releasing the lock mechanism 24 by the lock control means 21c. When canceling, the time when the event code input operation was performed is stored in the storage unit 22 as the input operation log together with the input event code. Note that an event code input operation log can be stored in the storage unit 22 so that it can be referred to separately during the aggregation process.
In the operation of the key management system 1 described above, an example has been described in which the first key 10 and the thirteenth key 10 are necessary for handling an event. However, the first key 10 and the thirteenth key are described. This is not limited to events that require 10 and the same applies to other events that require other keys 10.
Moreover, although it showed by an example with the key management machine 11 of the 1st unit, and the cash processing machine 12 which is a counter machine, it is not restricted to this structure, About other several key management machines 11 and several cash processing machines 12 Is the same.

  Therefore, according to the key management system 1 of the above-described embodiment, when an event that requires the key 10 occurs in the cash processing machine 12, the key of the key 10 necessary for handling the event from the cash processing machine 12 The identification information is output to the key manager 11 as a key take-out request signal. In the key manager 11 to which the key take-out request signal is input, the storage location of the key 10 necessary for handling the event by the recognition means 21a of the control unit 21. The key management is performed by using the display unit 16, the printer unit 20, and the speaker 25, which are output means, to output an instruction for taking out the key 10 necessary for handling the event stored in the determined storage location. From the storage location of the machine 11, the person in charge of taking out the key 10 necessary for handling the event or the administrator can operate the display unit 16, the printer unit 20, and the speaker 25. It is possible to perform the taking out of the key 10 required for compliance events in accordance with the output, incorrect to prevent unauthorized removal of the key 10, it is possible to reliably perform treatment for the event request.

Further, as compared with the conventional system which is not found until the push button 31 of the key holding unit 19 of the key management device 11 is pressed, the guidance that can be felt through the eyes or ears by the display unit 16, the printer unit 20 and the speaker 25. By adopting, useless operation can be prevented and the key 10 can be taken out quickly.
Only the key 10 necessary for handling the event can be taken out by controlling the lock mechanism 24 by the lock control means 21c, and the key 10 that is not necessary for handling the event is not allowed to be taken out. It is possible to prevent the wrong key 10 from being taken out and to more reliably take action on the event request.

  Furthermore, the display unit 16, the printer unit 20, the speaker 25 (output unit), and the lock control unit 21c can be activated only when the person in charge of taking out the key 10 or the administrator is logged in using the login unit 21b. Therefore, for example, when a person or administrator who is not in charge of taking out the key 10 logs in with a request unrelated to the event request, the functions of the display unit 16, the printer unit 20, the speaker 25, and the lock control unit 21c. Therefore, it is possible to prevent a person other than the person in charge of taking out the key 10 or a person other than the manager from taking out the key 10 necessary for handling the event.

  Further, when the guidance of the key 10 necessary for handling the event is provided by the display unit 16, the printer unit 20, and the speaker 25, which are output means, other keys other than the key 10 necessary for handling the event When the 10 person in charge of taking out or the administrator logs in by the login means 21b, the guidance by the display unit 16, the printer unit 20 and the speaker 25 is regulated so that only the key 10 other than the key 10 necessary for handling the event can be taken out. After this person or administrator logs out, it is possible to cancel the restriction of instruction output again and provide guidance to the person in charge or administrator who takes out the key 10 necessary for the event. Guidance for taking out the necessary key 10 is provided with a key 10 other than the key 10 necessary for handling the event. Since the lock control means 21c can prohibit the taking out of the key 10 necessary for handling the event while hiding it from the taking out person in charge, the taking out person of the other key 10 is allowed to take out the other key 10, It is possible to more reliably prevent erroneously taking out the key 10 necessary for handling an event.

  Further, there are a plurality of keys 10 that can be taken out by the person-in-charge authority or the manager authority, and another key 10 that has the right to take out in spite of the fact that the above-described guidance is provided for the key 10 that is requested to be taken out. Even if the removal button 31 of the key holding unit 19 holding the key is pressed, the release of the lock mechanism corresponding to the removal button 31 is restricted, so that the key 10 necessary for handling the event is restricted. Thus, it is possible to prevent the wrong key 10 from being taken out by a person in charge of taking it out or a manager and to reliably carry out the taking out.

  Further, by the second output means 23, the person in charge of taking out the key 10 necessary for handling the event owns the access right, for example, a high-level operation console of the cash processing machine 12 or a general-use PC or portable terminal Since the guidance for taking out the key 10 can be performed via an information terminal such as the above, the person in charge of taking out the key 10 or the administrator looks at the information terminal and uses the key necessary for handling the event with the key manager 11. After taking 10 out, you can head to the cash machine 12 where the event occurred. As a result, events such as ATMs and money changers installed in the automatic machine corner away from the person in charge or manager's office In the case of occurrence, after confirming the occurrence of the event with the cash processing machine 12, the key management machine 11 takes out the key 10 necessary for handling the event and returns it to the cash processing machine 12 again. As compared with the case where buy, it is possible to reduce the time of treatment.

  Then, the key manager 11 stores in the storage unit 22 time information from when the key take-out request signal is input to when the key treatment completion signal is input, so that the suspension time for each cash processor 12 can be determined as a key. The management machine 11 can perform centralized management.

  In addition, after the handling of the event of the cash processing machine 12 is completed using the key 10 necessary for handling the event, the key 10 is not returned to the key management machine 11 even after a predetermined time has elapsed. Since the person in charge or the administrator who has taken out can be prompted to return the key 10, it is possible to prevent the key 10 from being forgotten to be returned.

  Further, the key management machine 11 does not recognize the key take-out request signal, the cash handling machine 12 does not generate an event, the cash is loaded before the start of business, the cash cassette is removed after the business is finished, the maintenance check, etc. When the communication line between the cash processing machine 12 and the key management machine 11 is malfunctioning, the key 10 corresponding to the event code can be obtained by inputting the event code from the operation unit 15 (input means). Since it can be taken out, it is possible to strictly manage the key 10 when no event occurs in the key manager 11.

  Further, even if a predetermined time elapses after the key 10 of the key management machine 11 is taken out, if the event handling procedure is not performed in the cash processing machine 12, a warning is issued by the warning means 26 and the key 10 is copied. Can be prevented from being illegally used.

  In the above-described embodiment, the case where a key take-out request signal including key identification information is transmitted from the cash processing machine 12 to the key management machine 11 is described. However, the present invention is not limited to this configuration. As an embodiment, instead of the key identification information of the key take-out request signal, the key take-out request signal includes the storage location information of the key 10 (the number of the key holding unit 19), and each cash processor 12 performs cash processing. Each key 10 dedicated to the machine 12 is attached to the key holder attachment part 30 of which key holding part 19 of which key management machine 11, that is, the storage location information of the key 10 is stored in each cash processing machine 12. A configuration stored in advance may be used.

  With this configuration, when an event requiring the key 10 occurs, each cash machine 12 identifies and specifies the storage location of the key 10 corresponding to the required key 10 in the control unit 37, Since the storage location of the key 10 is included as information data of the key removal request signal and transmitted to the key management device 11, each key management device 11 uses the recognition means 21a by receiving the key removal request signal. The storage location of the key 10 can be directly recognized, and the storage location of the key 10 can be guided by the output means even if the recognition unit 21a of the above-described embodiment is omitted. However, in this case, as a restriction condition, the location of the key holding unit 19 is not changed so that the location of the key 10 and the key holding unit 19 is in one-to-one correspondence. It is necessary to fix to the place of the holding part 19.

  Further, in the key management machine 11 of the above-described embodiment, the key 10 and the key holding unit 19 have a one-to-one correspondence for convenience. However, since the key identification information can be read from the key holder 34, it is necessary. Accordingly, the operation may be set so that the plurality of key holding units 19 can take out / return one key 10. In this operation setting, for example, the key holder 34 of which key 10 is attached to which key holding unit 19 is stored in the storage unit 22 every time the key 10 is attached, and the key holder 34 of the specific key 10 is stored. Even if the location of the key holding unit 19 to which is attached is changed, this is grasped. When the specific key 10 is taken out, the stored information in the storage unit 22 is searched for which key holding unit 19 is attached to the specific key 10, and the lamp 32 of the corresponding key holding unit 19 is turned on. The key 10 is returned to any key holding unit 19 as long as the key holding unit 19 managed by the key management machine 11 is returned when the specific key 10 is allowed to be turned on and the key 10 is returned. Even if it is, allow return and lock.

  Furthermore, in the above-described embodiment, the case where guidance is performed using the display unit 16, the printer unit 20, and the speaker 25 as output means has been described. However, any method that can provide guidance as instruction output for taking out the key 10 may be used. It is not limited to the configuration.

  Moreover, although the case where the number of the key holding unit 19 that is the storage location of the key 10 is displayed and voice-output by a message has been described, the name (name) of the type of the key 10 (for example, a device key, a cash key, etc.) In association with the name (name) of the key 10 attached to the attachment unit 30, the information is stored in the storage unit 22 in advance, and when performing the above-described guidance, the name (name) of the key 10 is associated with the associated key holding unit 19. It may be included in the message described above together with the number for display and voice output.

  Further, the case where the cash processing machine 12 transmits a key take-out request signal to the key management machine 11 has been described. However, the present invention is not limited to this. For example, it is necessary to take out the key 10 in addition to the key take-out request signal. You may make it output the event information of the cash machine 12 which became. The event information indicates detailed information of an event that requires the key 10 in each cash processor 12. That is, it shows detailed information such as whether the cash safe 12 is in a full safe state, a reject storage is full, or an apparatus abnormality occurs. In addition, by including this event information as encoded data in the key takeout request signal, the key manager 11 stores the time when the key takeout request signal is received and the event information in the storage unit 22, and performs aggregation processing. You can refer to it separately. In this way, the key management machine 11 counts the detailed information of the events that require the key 10 for each cash processing machine 12, for example, the above-described survey of the downtime for each cash processing machine 12 and the like. Therefore, it will be possible to expect an effect that enables more detailed analysis.
