The operation of the key storage device 1 in the present embodiment having the above configuration will be described with reference to the flowcharts shown in FIGS.

That is, when the CPU 71 operates according to the program stored in the ROM 72, first, at step S1, the presence / absence state inspection processing is executed. As shown in FIG. 11, the presence / absence state inspection process stores the first to thirty-third keys in each of the storage units 21a to 26e in the key storage device 1.
3 to determine whether the first to thirty key holders 53 are housed, thereby checking the presence / absence state of each key 33, and checking the result of the check with the first to thirtieth keys secured in the RAM 73. This is the routine for recording the current data.

In step S2, the first to thirtieth current data acquired in the presence / absence state inspection processing is
After the data is transferred to the first to thirtieth past data secured in the AM 73, a card taking process is executed (S3).

In the card loading process, as shown in FIG. 12, the process waits until the card body 17 is inserted into the storage port 18 of the card holder 19 (SC1). When the card body 17 is inserted, the card body 17 is automatically conveyed into the card holder 19 (a natural fall method is also possible) (SC2), and is held in the card holder 19 (SC2).
3) Return to the main processing and perform the door opening processing (S4).

In the door opening process, as shown in FIG.
After outputting an ID number read command from the antenna 183 of the non-contact read / write device 83 installed in the card holder 19 (SD1), the read / write data carrier 19 of the card body 17 accommodated in the card holder 19 is output.
The ID number output from 1 is acquired (SD2). As described above, by performing communication between the non-contact read / write device 83 and the read / write data carrier 191 of the card body 17 in the card holder 19,
The distance from the antenna 183 of the non-contact read / write device 83 to the read / write data carrier 119 can be kept constant. This makes it possible to reliably obtain the ID number.

Then, it is determined whether or not the ID number obtained in the step SD2 matches one of a plurality of ID numbers stored in the RAM 73 in advance (SD
3) If the acquired ID numbers do not match the plurality of ID numbers stored in the RAM, a beep is sounded (SD8), and "1" is set in the first error flag.
Is written (SD9), and the process returns to step S5 of the main process. On the other hand, when the password matches one of the stored ID numbers, this is set as a condition for releasing the locked state of the door 13, and the control waits until a password is input from the numeric keypad 15 (SD4). In addition, unlocking can be performed without using a password by setting or the like.

When a password is entered from the numeric keypad 15, the registered password corresponding to the ID number obtained from the card body 17 and stored in the RAM 73 is read (SD5). It is determined whether or not the number matches the password input from the ten key 15 (SD6). If they do not match, a beep is sounded (SD8), "1" is written in the first error flag (SD9), and the process returns to step S5 of the main processing. Unlocks the door 13 (SD7), and returns to step S5 of the main process.

As described above, the ID number obtained from the card body 17 matches one of the plurality of ID numbers stored in the RAM 73 in advance, and the personal identification number input from the ten key 15 is obtained. The locked state of the door 13 is released only when the registered password matches the registered password corresponding to the registered ID number, so that the key in the storage unit main body 11 can be taken out only by the owner of the card body 17. Can be restricted and security can be increased.

In step S5, it is determined whether the first error flag is "0", that is, whether there is no error in the door opening process. If there is an error, the flow branches to step S13. Then, the card body 17 in the card holder 19 is ejected from the card ejection port 20, all error flags are set to "0", and the process returns to step S2.
If the first error flag is "0", that is, if there is no error in the door closing process, the process waits until the door 13 is closed (S6). Then, the presence / absence state inspection process is performed (S7).

In this presence / absence state inspection process, as shown in FIG. 11, the second error flag secured in the RAM 73 is set to "0" (SB1), and the RAM 7
The N secured in No. 3 is set to “1” (SB2), a read command is output from the Nth antenna provided in the non-contact reader device 88 (SB3), and the key information is received by the Nth antenna It is determined whether or not it has been performed (SB4). If the key information is not received as a result of the determination, it is determined that the key holder is not housed in the housing section in which the N-th antenna is installed, and the N-th current data set in the RAM 73 is used. Then, "0" indicating that there is no corresponding key in the storage unit is written (SB5), and step SB11 is executed.
Move to. Also, in step SB4, when the key information is received, it is determined that any key holder of the storage unit in which the Nth antenna is installed is housed, and this key information is obtained. (SB6).

Then, it is determined whether or not the obtained key information matches the key number assigned to the Nth key (SB7). If the key information does not match, the key holder accommodated in the accommodating portion is attached. A beep sound indicating that the received key is different from the storage unit to which the key is to be returned is emitted from the speaker (SB8), the second error flag is set to "1" (SB9), and the main process is started. Step S
Return to 8. In this way, when a key is returned to an accommodation unit other than the assigned storage position, this can be notified by a beep sound, and it is necessary to return each managed key to the assigned storage position. Can be promoted. Therefore, in order to return each key to the assigned storage position, each key must be provided with a key ring having a different shape, and the storage unit main body 11 must be provided with a key holder insertion portion into which only the corresponding key ring can be inserted. Compared to the conventional method, for example, as in the present embodiment, each key is provided with a key holder having a built-in data carrier for storing key information, and a storage unit capable of storing each key ring is provided in a storage unit. For example, the storage position may be set in the main body 11 so that the storage position can be set freely.

If the key information coincides with the key number assigned to the N-th key in step SB7, it indicates that the N-th current data has a key. Is written (SB10). As described above, since "1" indicating that a key is present or "0" indicating that there is no key is written in the N-th current data, it is possible to manage a key take-out state and a key return state. it can.

Then, 1 is added to the N (SB11), and if the N is 30 or less, the process returns to the step SB3, and repeats the processes (SB3 to SB12) to repeat the first to 30th. While the presence / absence state of the key in all of the storage units 21a to 26e is stored in the first to thirty current data, and when the N exceeds 30,
It returns to step S8 of the main processing.

In step S8, it is determined whether or not the second error flag is "0", that is, whether or not there is an error in the presence / absence state checking process. If the key returned in the presence / absence state inspection process has been returned to a different storage unit, the process branches to step S6, and repeats steps S6 and S7 until the key is returned to the corresponding storage unit. , If there are no errors,
A comparison storage process is performed (S9).

In the comparison storing process, as shown in FIGS. 14 and 15, first, the third error flag secured in the RAM 73 is set to "0" (SE1), and the R
Write "1" to N secured in AM73 (SE
2) Nth current data storing the current test result;
It is determined whether or not the N-th past data that stores the previous inspection result does not match (SE3). If it is determined that there is no key, and the process branches to step SE11, if the values do not match, it is determined that the key assigned to the Nth storage unit has been taken out and the Nth current data is larger than the Nth past data. It is determined whether or not (SE4).

At this time, the N-th current data and the N-th past data are stored in the N-th storage unit when the N-th key is present.
1 "is stored, and" 0 "is stored when the N-th key is not present in the N-th accommodating unit, so that in the step SE4, the N-th current data is changed to the N-th current data. If the data is larger than the past data, that is, if the value has changed from “0” indicating the absence of the key to “1” indicating the presence of the key from the previous time, it is determined that the Nth key has been returned, and the real-time clock 86 And the return time, the ID number read from the card body 17,
The key information stored in the data carrier of the N-th key holder is stored in the RAM 73 together with the return time (SE5), and the flow shifts to the step SE11. Also,
If the Nth current data is smaller than the Nth past data,
That is, when the key has changed from “1” indicating the presence of the key to “0” indicating the absence of the key from the previous time, it can be determined that the N-th key has been taken out, and the key taken out is identified. can do. The use permission information stored in the RAM 73 for each ID number read from the card body 17, specifically, a key number that can be taken out with the ID number is stored in the RAM 73.
Then, it reads out (SE6) and determines whether or not the N-th key is usable (SE7).

If the result of this determination is that the key is not usable, that is, if a key other than the use permitted is taken out, a beep is sounded (SE8), and the third error flag is set to "1" (SE9). ), Step S1 of the main processing
Return to 0. As a result, it is possible to warn that a key other than the use permission is taken out.

If a usable key is taken out in step SE7, the current time indicated by the real-time clock 86 is taken as the take-out time, and the ID number read from the card body 17 is taken out. And the key information stored in the data carrier of the N-th key holder are stored in the RAM 73 together with the carry-out time (SE10), and the flow shifts to the step SE11.

In the step SE11, 1 is added to the N, and when the N is 30 or less, each of the steps SE is added.
3 to SE12 are repeated, and the first to thirtieth accommodation units 2 are repeated.
It is checked whether or not there is a change in the key take-out state and the return state of all the keys 1a to 26e and stored in the RAM 73, and when the N exceeds 30, the process returns to step S10 of the main processing (SE12). . As described above, the state of the insertion / removal of the key in each of the storage sections provided at the respective storage positions is determined by the ID number read from the card body 17, the key information stored in the data carrier of the key holder, Alternatively, since it can be stored in the RAM 73 as the return time, it is possible to manage when and by whom each key was taken out and returned.

In the step S10, it is determined whether or not the third error flag is "0", that is, whether or not a key other than the use permission has been taken out. 13 is locked (S11), and the information writing process is performed (S12).
The process branches to step S6, where the key other than the use permission taken out is returned to the original position, and the third error flag is set to "
Steps S6 to S10 are repeated until the value becomes "0".

Thus, not only is the beep sounded (the abnormal state signal may be output to the outside) until the key other than the use permission taken out is returned to the original correct position, Return of the card body 17 is also refused. As a result, the holder of the card body 17 cannot remove the card body 17, so that erroneous use of keys other than permission to use and further unauthorized use can be prevented.
Therefore, a key ring having a different shape corresponding to the number of keys to be managed is prepared, and a key ring insertion portion into which only the corresponding key ring can be inserted and a complicated mechanism such as a lock mechanism corresponding thereto are not provided, and the key ring is misused. In addition, an improper use can be prevented, and an improper use prevention device which can prevent improper use at a very low price can be obtained.

In the information writing process, as shown in FIG. 16, after a write command is output from the antenna 183 of the non-contact read / write device 83 installed in the card holder 19 (SF1), the comparison is performed. The key information recorded in the recording process and the take-out time or the return time are output as write data (SF2), and the read / write data carrier 19 of the card body 17 stored in the card holder 19 is output.
The process waits until the writing time required for writing to No. 1 has elapsed (SF3), and returns to step S13 of the main process. In this manner, the key information of the taken-out or returned key and the time taken out or returned can be stored as write data in the read / write data carrier 191 of the card body 17. This card body 1
It is possible to manage the use status of each key by the seven holders. Also, at this time, the writing process of the card body 17 to the read / write data carrier 191 is performed in the card holder 119, so that the process from the antenna 183 of the non-contact read / write device 83 to the read / write data carrier 191 is performed. Can be performed in a state where the distance is kept constant, and the writing of the write data can be performed more reliably than in the case where there is a risk that the holder of the card body 17 may move.

In step S13, the card body 17 accommodated in the card holder 19 is ejected from the card ejection port 20, and all error flags are set to "0" (S1).
4) Return to step S2, and repeat the processing from step S2 to step S14.

In this embodiment, the case where the object to be used is a key has been described as an example, but the present invention is not limited to this. Further, in the present embodiment, the storage medium is realized by a non-contact card, but is not limited to this, and may be an IC card, a magnetic card, or the like.

Further, the case where a beep sound is emitted when a key other than the use permission is taken out and this is reported has been described as an example. However, for example, the administrator is notified by communication using a communication line. You may report. Furthermore, each accommodation part 21a
LED is added to ２６26e, LED is blinked in conjunction with beep sound when returning wrong, or L when taking out is permitted.
The operability can be improved by turning on the ED.

As described above, in the misuse prevention apparatus according to the first aspect of the present invention, when the stored object is taken out of the storage unit main body, the storage medium on which the identification information is stored. Is stored in the storage means, and it is determined that the identification information stored in the storage medium matches one of the plurality of pieces of identification information stored in the information storage means. Therefore, it is possible to restrict taking-out of the used object in the storage unit main body by a person other than the storage medium holder, and to maintain security.

Then, when the door is opened and the object stored in the storage unit main body is taken out, the taken-out object is specified, and the used object is identified by use permission information. If the used object does not indicate permission to use, the ejection of the storage medium stored in the storage unit can be refused until the taken out used object is returned. As a result, the storage medium holder cannot remove the storage medium, so that erroneous use and unauthorized use of the stored object can be prevented.

Therefore, it is possible to prepare a key holder having a different shape corresponding to the number of objects to be managed, and to provide a key holder insertion portion into which only the corresponding key holder can be inserted and a complicated mechanism such as a lock mechanism corresponding thereto. Since misuse can be prevented, manufacturing or management costs can be suppressed, and a misuse prevention device that can prevent misuse at a very low price can be obtained.

Further, in the misuse prevention device according to the second aspect, an output step of outputting a read command to the data carrier of the card body when acquiring identification information from a data carrier built in the card body, The distance to the data carrier can be kept constant by performing the communication including the obtaining step of obtaining the identification information output in response to the read command in the accommodation unit. This makes it possible to reliably obtain the identification information.

Further, in the misuse prevention device according to the third aspect,
The object specified by the specifying unit can be stored as write information in the data carrier of the card body stored in the storage unit. As a result, it is possible to manage the usage status of the object used by the card holder and to exchange information with the usage status management device installed in a different place using the card as a medium, so that the There is no need for connection or laying work for that purpose. Further, by performing the writing process of the card body on the data carrier in the housing means, a series of writing operations can be performed while maintaining a constant distance to the data carrier. The write information can be stored more reliably than in a case where the holder may move.
