For example, display of this cash processing machine The person in charge can be prompted by displaying a key return request on the device.

A key management system according to an embodiment of the present invention will be described below with reference to the drawings.
The key management system of the present embodiment is used in a store of a financial institution such as a bank. As shown in FIG. 1, a plurality of units installed in a space where only a clerk such as a management room is allowed to enter. A key management device 11 and a plurality of cash processing machines 12 used by a bank employee or customer for cash processing such as depositing, withdrawing or exchanging money are connected to each other via a LAN 13 which is a communication means so as to communicate with each other. Has been.

  As shown in FIG. 2, each of the plurality of key management devices 11 holds the key 10 in a detachable manner, and includes an operation unit 15 including a numeric keypad on which a person in charge can input a password or the like. 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 the identification information of the person in charge from the ID card, a number of key holders 19 that hold the corresponding keys 10 detachably, and prints necessary information on paper. A printer unit (output unit) 20 that can be used, a control unit (comparison / collation unit) 21 shown in FIG. 1 connected thereto, and a storage unit 22 that can exchange data with the control unit 21.

  As shown in FIG. 2, the key 10 has a key body 25 and a key holder 26 connected to the key body 25, and the key holder 26 stores individual key identification information for identifying the key from others. An ID chip (not shown) is embedded. The key 10 is an operation key mainly for switching on / off the main power supply of the cash processing machine 12, but is not an operation key of the cash processing machine 12, for example, for opening and closing a door that is opened when the cash cassette of the cash processing machine 12 is attached / detached. The key is also included.

  The key holding unit 19 of the key management device 11 includes a key holder mounting unit 30 that holds only the key holder 26 of one key 10 that corresponds one-on-one in a locked state, and a key holder mounting unit that constitutes the same key holding unit 19. It has the removal button 31 pressed when canceling the locked state of 30, and the lamp | ramp 32 which can be lighted and blinked. When the key holder 26 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 and the source key holder mounting unit 30 correspond to each other. The key holder 26 is locked by the key holder mounting portion 30. Further, the key holder mounting part 30 unlocks the key holder 26 when the removal button 31 is operated under the conditions approved by the control part 21.

  The storage unit 22 of the key management device 11 stores data related to taking out and returning 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 person-in-charge identification 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, in the case of ranking, for example, it is divided into a general job, a window job, a back job, a management job, etc., and key identification information of the key 10 that can be taken out is stored in association with each rank. . Further, when the key 10 that can be taken out is different for each person in charge even in the same rank, the key identification information that can be taken out is stored in association with each person identification information. Furthermore, key identification information of the key 10 that requires the approval of the senior manager is also stored.

  When the person in charge takes out the key 10, first, the card reader 18 scans the ID card 17 and inputs the password set for permission to take out the key 10 to the operation unit 15. Then, the card reader 18 transmits the person-in-charge identification information of the read ID card 17 and the input personal identification number to the control unit 21, and the control unit 21 collates with the master data stored in the storage unit 22. Thus, when the person-in-charge identification information and the personal identification number are appropriate, the lamp 32 of the key holding unit 19 holding the key 10 having the key identification information that can be taken out with respect to the person-in-charge identification information is turned on. Note that biometric authentication such as fingerprint authentication may be performed instead of the input of the password.

  When the takeout button 31 of the key holding unit 19 whose lamp 32 is lit is operated by the person in charge, the control unit 21 releases the lock state of the key holder mounting unit 30 of the key holding unit 19 and removes the key 10. The identification information of the person in charge of the ID card 17 read when the key 10 is taken out, the key identification information of the key 10, the take-out time (date and time) when the take-out 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 return time (date and time. Since the data has not been returned at this time, the data is blank). Then, the person in charge takes out the key 10 from the key holding unit 19 by releasing the locked state of the key holder mounting unit 30. As a matter of course, even when the takeout button 31 of the key holding unit 19 other than the lamp 32 turned on is operated, the control unit 21 releases the locked state of the key holder mounting unit 30 of the key holding unit 19. There is no.

  Further, when the person in charge returns the key 10, the key holder 26 of the key 10 is inserted into the key holder mounting part 30 of the one key holding part 19 corresponding one-to-one. Then, the control unit 21 reads the key identification information from the key holder 26 and locks the key 10 so that it cannot be taken out only when the key identification information corresponds to the key holding unit 19 on a one-to-one basis. At the same time, it is confirmed that the key 10 has been returned with the latest information on the return and return status data having the key identification information stored in the storage unit 22 indicating that the key 10 was being taken out. The information is rewritten to the holding information shown, and the locked time is written in the return time (date and time) that was left blank. When the key identification information read from the key holder 26 does not correspond to the key holding unit 19 to which the key identification information is attached, the control unit 21 notifies the user of the error by, for example, blinking the lamp 32 without locking the key holder 26. . Note that the key 10 may be locked by the key holder mounting unit 30 described above on the condition that the appropriate ID card 17 is scanned by the card reader 18 when returning.

  The control unit 21 of each key management apparatus 11 is configured so that the carry-out return status data regarding the take-out and return of the key 10 is always updated to the latest every time the key 10 is taken out and returned.

  Each of 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, and a cash processing mechanism unit 38 that performs cash processing. And a control unit 37 connected thereto. 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 are further installed in the headquarters of a financial institution outside the store. Is connected to the headquarters server and controls cash processing.

  The plurality of cash processing machines 12 can operate by attaching the key body 25 of one key 10 corresponding to each one to one to a key cylinder (not shown) and performing an ON operation. The key 10 cannot be turned on with the key 10 not to be operated, and the operation is impossible. Also, when taking out the internal cash cassette, the key body 25 of one key 10 corresponding one-to-one is mounted on a key cylinder (not shown) and is turned ON, so that the door (not shown) can be opened. ing.

  When the key body 25 of one corresponding key 10 is attached to the key cylinder and is turned ON, the control unit 37 of each cash processing machine 12 uses the key identification information of the key 10 and the use of the key 10. Use start time (date and time) when the key 10 is started, in-use information indicating that the key 10 is in use, and use end time (date and time when the key cylinder is turned OFF with the key 10. Therefore, the operation status data relating to the use of the key 10 is output to the plurality of key management apparatuses 11 via the LAN 13.

  The control unit 21 of each key management device 11 is input with operation status data from each cash processing machine 12 via the LAN 13 so that it can be updated at any time. That is, when the key identification information included in the operational status data input from each cash processing machine 12 via the LAN 13 is stored in the storage unit 22, that is, the control unit 21 should hold the key identification information. If it is the key identification information of the key 10, the operation status data is stored in the storage unit 22 in association with the latest take-out return status data stored in association with the key identification information. When the key identification information included in the input operational status data is not stored in the storage unit 22, the control unit 21 ignores it as irrelevant data.

  After that, when the key cylinder is turned off with the key 10 in the cash machine 12, the control unit 37 of the cash machine 12 indicates the key identification information of the key 10 and the non-use of the key 10 indicating that the key 10 is not in use. Use end time data related to the use of the key 10 including the in-use information and the use end time (date and time) when the key cylinder is turned off with the key 10 is sent to a plurality of key management apparatuses 11 via the LAN 13. Output. Then, in each key management device 11, when the control unit 37 stores the key identification information included in the input use end time data in the storage unit 22, that is, the key 10 that the key identification information itself should hold. The key 10 is in use in the operation status data stored in association with the latest carry-out return status data stored in association with the key identification information. The in-use information is rewritten to non-in-use information indicating that the key is not used, and the end-of-use time included in the end-of-use time data input this time is written to the storage unit 22 in the blank of the end-of-use time. Remember me. When the key identification information included in the input operational status data is not stored in the storage unit 22, the control unit 21 ignores it as irrelevant data.

  In each key management device 11, the control unit 21 takes out the identification information of the person in charge who took out the key 10, take-out return status data including the take-out time and the return time, and the key 10 in the cash processor 12 corresponding to the key 10. The operation status data related to use is compared and collated, and the display unit 16 displays and outputs the comparison and collation result. At this time, the control unit 21 arranges the comparison and collation results for each person identification information of the person in charge and for each identification key-specific information of the key 10 to be taken out. Thus, the second organizing mode displayed on the display unit 16 can be selectively switched. The display unit 16 includes a display screen (output unit) 16a for performing display, and a touch panel (switching operation unit) 16b attached on the display screen 16a. The control unit 21 includes a first display screen 16a. The display in the organization mode and the display in the second organization mode are switched by a touch operation on the touch panel 16b.

  Further, in each key management device 11, the control unit 21 determines the occupancy status of the key 10 from the comparison result of the carry-out return status data and the operation status data, the normal level of the use state and the use standby state, and the non-use. The abnormality level is classified into two types, and the abnormality level is further classified into two types, a warning level in a mild non-use state and a warning level in a severe non-use state, and is displayed on the display unit 16. Let

  For example, after the key 10 is taken out from the key management device 11, the cash processing is performed before a predetermined time that is predicted to start using the cash processing machine 12 corresponding to the key 10 on a one-to-one basis. When the use in the machine 12 is started, the control unit 21 determines that the occupation state of the key 10 is a normal level and causes the display unit 16 to display the fact. Further, for example, after the use of the key 10 in the cash processing machine 12 is finished, the key 10 is stored in the corresponding key management apparatus 11 before a predetermined time predicted to be returned to the corresponding key management apparatus 11 elapses. Even when it is returned, the control unit 21 determines that the occupation state of the key 10 is a normal level, and displays that fact on the display unit 16.

  On the other hand, after the key 10 has been taken out from the key management device 11, the control unit 21 has passed a predetermined time when it is predicted that use of the cash processor 12 corresponding to the key 10 will be started. If the use with the cash processing machine 12 is not started, it is determined that the occupancy status of the key 10 is an abnormal level, and that effect is displayed on the display unit 16. At this time, if there is a possibility that use in the cash processing machine 12 may not start even after a predetermined time has passed after taking out due to the relationship with other keys 10 taken out at the same time, a mild attention level And the display unit 16 displays that effect. On the other hand, if there is no possibility that the use with the cash processing machine 12 will not be started even after a predetermined time has passed after taking out the key 10 in relation to another key 10 taken out at the same time, the key 10 is occupied. The situation is determined to be a severe attention level, and the fact is displayed on the display unit 16.

  For the convenience of explanation, the specific control contents of the control unit 21 are a plurality of keys 10 as keys X1 to X6 for identification, a plurality of cash processors 12 as cash processors Y1 to Y6 for identification, and a plurality of keys. The key management device 11 will be described as Z1 and Z2 for identification. At this time, the key X1 is an operation key dedicated to the cash processor Y1, the key X2 is an operation key dedicated to the cash processor Y2, the key X3 is an operation key dedicated to the cash processor Y3, and the key X4 is a cash process. This is an operation key dedicated to the machine Y4, the key X5 is an operation key dedicated to the cash processing machine Y5, and the key X6 is an operation key dedicated to the cash processing machine Y6. The keys X1 to X6 are managed by the same key management device Z1.

  First, the control unit 21 of the key management device Z1 performs arrangement in the first arrangement mode in which the person-in-charge identification information is arranged and displays the result on the display screen 16a of the display unit 16 with reference to FIG. explain. 3A is a display example of the display screen 16a, and FIG. 3B is an explanatory diagram thereof.

  In the uppermost area of the display screen 16a of the key management device Z1, the person in charge who has the ID card 17 having the person-in-charge identification information A takes out one key X1 for the cash processing machine Y1 from the key management apparatus 11. A display example is displayed.

  The person in charge who has the ID card 17 having the person-in-charge identification information A scans the ID card 17 with the card reader of the key management device 11, and takes out the key X1 within the range of take-out authority from the key management device Z1 (t01). Time). Then, the control unit 21 of the key management device Z1 performs responsible person identification information A that is identification information of the responsible person, key identification information of the key X1, take-out time t01, and a holding key that indicates that the key X1 is being taken out. The storage unit 22 stores take-out return status data including out-going information and a blank return time.

  Next, when the cash processing machine Y1 is turned on with the key X1 and is activated (at time t02), the control unit 37 of the cash processing machine Y1 uses the key identification information of the key X1 and the use of this key X1. Operation status data related to the use of the key X1 including the use start time t02 at which the key X1 is started, the in-use information indicating that the key X1 is in use, and the use end time set to the blank, To the key management devices Z1 and Z2. Then, in the key management device Z1, since the key identification information is the key identification information of the key X1 to be held by itself, this operation is associated with the take-out return status data stored in association with the key identification information. The status data is stored in the storage unit 22.

  After that, when the cash processing machine Y1 is turned off with the key X1 at the end of the business or the like (at time t03), the control unit 37 of the cash processing machine Y1 does not use the key identification information of the key X1 and the key X1. End-use time data related to the use of the key X1 including the non-use information indicating that the cash processing machine Y1 is turned off with the key X1 and the key management device Z1 via the LAN 13. , Z2. Then, in the key management device Z1, since the key identification information included in the input use end time data is the key identification information of the key X1 to be held by itself, the operation stored in association with this key identification information In the status data, the in-use information indicating that the key X1 was in use is rewritten to non-in-use information indicating that the key X1 has not been used, and the use that has been entered this time in the blank for the end-of-use time The use end time t03 included in the end time data is written and stored in the storage unit 22.

  When the key X1 is returned to the key management device Z1 (at time t04), the control unit 21 of the key management device Z1 is taking out the key X1 with respect to the take-out return status data having the key identification information of the key X1. The taking-in information indicating that the key X1 has not been taken out is rewritten to the holding information indicating that the key X1 is not being taken out, and the return time t04 is written in the blank for the return time and stored in the storage unit 22.

  In the flow as described above, the control unit 21 of the key management device Z1 compares the carry-out return status data with the operation status data in real time, and displays the status up to that point on the display screen 16a in real time. Will do.

  At that time, the control unit 21 of the key management device Z1 classifies the occupancy status of the key X1 into two types of normal level and abnormal level based on the result of comparison and comparison between the carry-out return status data and the operation status data. Is displayed on the display screen 16 a of the display unit 16.

  That is, the control unit 21 of the management device Z1 takes out the key X1 from the time t01 when the key X1 is taken out from the key management device Z1 and the time t02 when the use of the cash processing machine Y1 is started. If the use at the cash processing machine Y1 has started before the predetermined time T01 that is expected to be used at the cash processing machine Y1 later (t02-t01 <T01), the key X1 is occupied. The situation is determined to be a normal level. The example shown in FIG. 3 is a case of a normal level, and there is no particular display of colored abnormal levels, which will be described later. That is, a state where there is no particular indication about the level represents a normal level.

  In addition, the control unit 21 of the management device Z1 manages the key after the use ends from the time t03 when the use of the key X1 in the cash processing machine Y1 is completed and the time t04 when the key X1 is returned to the key management device Z1. If the key has been returned to the key management device Z1 before the predetermined time T02 predicted to be returned to the device Z1 (t04-t03 <T02), it is determined that the occupation state of the key X1 is at a normal level. To do. The example shown in FIG. 3 is a case of a normal level, and the display screen 16a of the display unit 16 of the key management device Z1 does not particularly display a colored display at an abnormal level, which will be described later.

  In the second area from the top of the display screen 16a of the key management device Z1, the person in charge with the ID card 17 having the person-in-charge identification information B receives two keys for the cash processors Y2 and Y3 from the key management device Z1. A display example when the keys X2 and X3 are taken out is displayed.

  The person in charge having the ID card 17 having the person-in-charge identification information B scans the ID card 17 with the card reader 18 of the key management device Z1, and the keys X2 and X3 within the range of the take-out authority from the key management device Z1. Take out (at time t11). Then, the control unit 21 of the key management device Z1 is taking out the person-in-charge identification information B as the person-in-charge identification information, the key identification information of the keys X2 and X3, the take-out time t11, and the keys X2 and X3. The storage unit 22 stores take-out return status data including information indicating that this is in progress and a blank return time.

  Next, when the cash processing machine Y2 is turned on with the key X2 and activated (at time t12), the control unit 37 of the cash processing machine Y2 uses the key identification information of the key X2 and the use of this key X2.
