  The locking / unlocking device is a device that locks and unlocks the door with an electric actuator, and is controlled by a predetermined management control means. An identification code is assigned to the remote terminal device. And if the said management control means recognizes a user's identification code through a remote terminal device, based on this identification code, it controls a locking / unlocking device so that only the door of the cabinet permitted to the said user is unlocked. It is the composition to do.

  By the way, in the cabinet system as described above, for example, for the purpose of improving security, there is a case where it is requested to manage the usage history such as which cabinet each user has used. For this purpose, the management control means controls the locking and unlocking device so as to avoid simultaneous use by a plurality of people in the cabinet to be managed, in other words, one user can use only one cabinet. There is a need.

  As a prior art related to the invention of the present application, for example, there is one described in Patent Document 1.

  The microcomputer 34a includes a CPU 31a, a ROM 32a, a RAM 33a (storage means), and the like, and operates according to a program stored in the ROM 32a. The RAM 33a stores the management group information table shown in FIG. 4, the user information table shown in FIG. 5, the security level information table shown in FIG. 6, and the usage history in a rewritable manner. It functions as a storage unit of the means. The microcomputer 34 a of the master unit 30 a determines the availability of each cabinet 10 based on the status of each table and the switch 42 and sensor 44 of each cabinet 10, and the determination result is sent to the slave unit via the communication line 52. 30b. The contents of the management group information, the user-specific information table and the security level-specific information table, and operations based on these will be described in detail later.

  Further, as shown in FIG. 7, the above-mentioned RAM 33a stores hourly security level pattern tables for one day. Then, the master unit 30a updates the security level information table (see FIG. 6) based on the hourly security level pattern table. The contents of the hourly security level pattern table and the operation based thereon will be described in detail later.

  Further, the microcomputer 34 a is connected to the switch 42 and the sensor 44 through the input circuit unit 36. When the user operates the switch 42, a signal to the effect is provided to the microcomputer 34a through the input circuit unit 36. That is, the switch 42 functions as an input unit that receives an unlocking instruction. The sensor 44 is means for detecting the open / closed state of the door or the drawer. An open / close detection signal from the sensor 44 is given to the microcomputer 34a via the input circuit section 36.

  The microcomputer 34 a is connected to the solenoid 21 and the display unit 46 via the output circuit unit 37. Then, the solenoid 21 is driven through the output circuit unit 37 and the drive circuit to control the locking / unlocking device 20, and the display operation by the light emission of the display unit 46 is controlled. In addition, according to display operation control to the display part 46, the display of the cabinet 10 which can be mentioned later, an error display, etc. are made | formed.

  The power supply unit 48 is means for supplying power to the electrical components of each cabinet 10 including the master unit 30a and the like. FIG. 3 shows only a part of the power supply line.

<C3: Description of the part incorporating the slave unit 30b>
In each cabinet 10 other than the one in which the master unit 30a is incorporated, the slave unit 30b, the switch 42, the sensor 44, and the display unit 46 are incorporated, and the card reader 40 is incorporated as necessary.

When an operation signal from the switch 42 and a detection signal from the sensor 44 are input to the microcomputer 34 b through the input circuit unit 36, a signal corresponding to each input signal is transmitted from the communication circuit unit 35 through the communication line 52. It is transmitted to the microcomputer 34a of 30a. Further, a command relating to the locking operation or unlocking operation of each locking / unlocking device 20 is given from the microcomputer 34 a of the master unit 30 a to the microcomputer 34 b through the communication line 52 and the communication circuit unit 35. The microcomputer 34b controls operations of the locking / unlocking device 20, the display unit 46, and the like according to a command related to the locking operation or the unlocking operation.

  The card reader 40 is provided in at least one of the cabinets 10. That is, instead of providing the card reader 40 in the cabinet 10 incorporating the master unit 30a, the card reader 40 may be incorporated in the cabinet 10 incorporating the slave unit 30b. Further, the card reader 40 may be provided in the cabinet 10 incorporating the master unit 30a, and the card reader 40 may be provided in at least one of the cabinets 10 incorporating the slave unit 30b.

<C4: Description of management PC>
The management personal computer 50 is composed of a general personal computer, and is communicably connected to the master unit 30a via a communication line.

  Through the management personal computer 50, for example, the tables shown in FIGS. 4 to 6 can be set or changed.

  As for the table shown in FIG. 7, a table for one week is set and stored in the storage unit 51 (for example, a hard disk device) on the management personal computer 50 side, and one table is stored every day at a predetermined time (for example, midnight). The contents of the table for the day are given to the master unit 30a, and the table in the RAM 33a is rewritten. That is, the management personal computer 50 has a function as an updating unit that gives a command to update the security level pattern table for each time zone in a predetermined period (every day in the above example).

  Of course, for the table shown in FIG. 7, for example, the contents of the RAM 33a may be individually rewritten by a specific input operation or the like through the management personal computer 50 every predetermined period.

  Further, the management personal computer 50 also has a function of collecting the usage history stored in the RAM 33a at a predetermined timing and storing it in an internal storage means.

<C5: Contents of each table>
The management group information table shown in FIG. 4 is a table in which each cabinet 10 is associated with each card reader 40. In FIG. 4, it is shown as a table in which the assigned cabinet number is associated with the identification code of each card reader 40. The identification code of the card reader 40 is a code assigned to each card reader 40. The assigned cabinet number is information regarding whether or not each cabinet 10 is assigned, and each digit is associated with each cabinet 10. In the example shown in FIG. 4, the cabinet 10 corresponding to the first to third digits from the left is assigned to the card reader 40 (CR01), and the card reader 40 (CR02) is fourth from the left. And the cabinet 10 corresponding to the fifth digit is assigned. As will be described later, when the user is identified through the card reader (CR01), it can be used in the cabinet 10 corresponding to the first to third digits, and the user can be identified through the card reader 40 (CR02). When the determination is made, the cabinet 10 corresponding to the fourth and fifth digits can be used.

  Basically, it is assumed that each cabinet 10 is grouped so as not to overlap, and each group is associated with one or more card readers 40, and one person is assigned to each group. Only a mode in which the cabinet 10 can be used is assumed. This embodiment is also described based on that premise.

  However, an example in which each cabinet 10 is partially overlapped and grouped and each group is associated with one or more card readers 40 can be assumed. In this case, in order to specify a user and leave a history, it is preferable to control the cabinet 10 so that only one person can use it across a plurality of partially overlapping groups.

  The management group information table shown in FIG. 4 is appropriately rewritten through the input interface of the management personal computer 50, for example. That is, the association of each cabinet 10 with each card reader 40 can be changed as needed.

  The user-specific information table shown in FIG. 5 is a table in which a user ID, an accessible cabinet number, and a security level are associated with each card ID.

  The user ID is an identification code assigned to each user, and the user ID of the user is specified by referring to the user-specific information table based on the acquired card ID. Based on the identified user ID, usage histories and the like by each user described later are stored and managed.

  The accessible cabinet number is information regarding the availability of each cabinet 10. For example, each of the 12 digits “101100101101” shown in the second frame from the top in the third column from the left in FIG. 5 is associated with each of the 12 cabinets 10. Indicates whether or not the user can use (access). For example, “0” in each digit indicates that the digit is not usable (access is impossible), and “1” in each digit indicates that the digit is usable (accessible). For example, the cabinet 10 associated with the second, fifth, sixth, eighth, and eleventh digits from the left cannot be used for the user having the card ID “234769”. Cabinet 10 is defined as available.

  The security level represents the security level assigned to the user in this system. That is, in this system, a plurality of security levels are set. Here, for example, security levels of “1”, “2”, “3”, “4”, and “5” are set. For example, a security level “3” is associated with a user having a card ID “234769”. The contents of each security level are defined in the security level-specific information table described below.

  This table by user information is information in which an accessible cabinet number, which is the availability information of each cabinet 10, is associated with the card ID associated with each user, that is, the cabinet for each user. The information includes the availability information for each user that associates 10 availability information. The user-specific information table includes user level assignment information in which one of the security levels is associated with each user. Of course, these pieces of information may be stored as separate tables.

  Such a user-specific information table is set and changed via, for example, an input interface of the management personal computer 50.

  The security level-specific information table shown in FIG. 6 is a table in which an accessible cabinet number is associated with each security level.

  The accessible cabinet number is information regarding the availability of each cabinet 10. For example, twelve digits of “000000000000” shown in the second frame from the top in the right column of FIG. 6 are associated with twelve cabinets 10, respectively. Indicates whether it is possible.

  Here, the cabinets 10 that can be used sequentially from the security level “1” to “5” are increased, that is, the confidentiality is gradually reduced.

  For example, “0” in each digit indicates that the access is not possible (access is impossible), and “1” in each digit indicates that the access is possible. For example, at the security level “1”, all cabinets 10 are defined as unusable, and at the security level “2”, the cabinets 10 associated with the first, second, third, and twelfth digits from the left. Is defined as available and the others are defined as unavailable. At the security level “5”, the cabinets 10 associated with the first to ninth digits from the left are defined to be usable, and the cabinets 10 associated with the tenth to twelfth digits from the left are defined. Is defined as not required.

  In general, the plurality of security levels are ordered in a predetermined order. That is, each security level is defined so that the number of objects of the cabinet 10 that can be used in a predetermined order increases or decreases so that security becomes strict in the predetermined order. However, it does not necessarily have to be ordered according to security.

  This security level-specific information table includes security level-specific availability information that associates the availability of each cabinet 10 with a plurality of security levels.

  Such a security level-specific information table is appropriately set and changed as will be described later, for example, according to a time-specific security level pattern table.

  The hourly security level pattern table shown in FIG. 7 is a table in which a security level pattern is associated with a change time. The security level pattern is a pattern in which an accessible cabinet number is associated with each security level. In other words, the hourly security pattern table stores information (security level pattern information) on the availability of each cabinet 10 for each security level in which the availability of the storage means is associated with a plurality of security levels. It includes security level pattern information for each time zone associated with each zone. The time zone mentioned here may be a case in which the time zone is distinguished by day of the week, month, etc., in addition to the time in the 24 hours a day.

  In the example shown in FIG. 7, the pattern A is associated with the change time “0:00”, the pattern B is associated with the change time “6:00”, and the change time “12:00”. The pattern C is associated with the pattern, the pattern D is associated with the change time “13:00”, and the pattern E is associated with the change time “18:00”. For example, in pattern A, “000... 000” for security level “1”, “000... 000” for security level “2”, and “000 for security level“ 3 ”. ... 000, security level “4” is defined as “000... 001”, and security level “5” is defined as “010. In other words, the pattern A is associated with the time zone “0:00 to 6:00”, the pattern B is associated with the time zone “6:00 to 12:00”, and similarly “12: 0 to 00”. Patterns C, D, and E are associated with “13:00”, “13: 0 to 18:00”, and “18: 0 to 0:00”, respectively.

<D: Operation>
Hereinafter, the operation of the cabinet system will be described.

<D1: Operation of locking / unlocking>
FIG. 8 is a flowchart showing the operation of the cabinet system.

  First, when the user holds the ID card 18 over one of the card readers 40, the card reader 40 reads the card ID from the ID card 18.

  In step S1, the master unit 30a makes the card reader 40, which is the reading source, unreadable, and then proceeds to step S2. When a plurality of card readers 40 are associated with the same group, the card readers 40 belonging to the same group are similarly made unreadable (see, for example, card readers CR2 and CR3 in FIG. 12). .

  In step S2, the master unit 30a refers to the user-specific information table and determines whether or not the read card ID is registered. Here, if it is determined that the read card ID is registered, the process proceeds to step S3.

  In step S3, the cabinet 10 associated with the card reader 40 that has become the reading source is specified based on the identification information of the card reader 40 that has become the reading source and the management group information table (see FIG. 4).

  Subsequently, in step S4, the master unit 30a, based on the read card ID and the user-specific information table (see FIG. 5), the accessible cabinet number corresponding to the user (that is, the availability information of each cabinet). To decide.

  In subsequent step S5, the master unit 30a specifies the security level of the user based on the read card ID and the user-specific information table (see FIG. 5).

  Further, in step S6, the master unit 30a, based on the specified security level and the security level-specific information table (see FIG. 6), the accessible cabinet number corresponding to the security level (usability information on each cabinet). To decide.

  In the subsequent step S7, the master unit 30a is identified within the range of the cabinet 10 identified in step S3, the accessible cabinet number determined in step S4, and the identified cabinet number determined in step S6. Whether to use each cabinet 10 is finally determined based on both the accessible cabinet number corresponding to the security level.

  Here, for each specified cabinet 10, both the contents for determining availability of the cabinet 10 according to the user (step S <b> 4) and the contents for determining availability of the cabinet 10 according to the security level (step S <b> 6). Is finally determined that the corresponding cabinet 10 can be used.

  In other words, for each identified cabinet 10, the accessible cabinet number obtained in step S4 and the accessible cabinet number obtained in step S6 are ANDed for each digit to obtain the accessible cabinet number. This is the final decision. As a specific example, for each specified cabinet 10, the accessible cabinet number obtained in step S4 is “101100101101”, and the accessible cabinet number obtained in step S6 is “0000011111111”. The accessible cabinet number is “00000001101”. The specified cabinet 10 may be limited before or after the logical product operation.

  When it is determined in step S7 whether or not the specified cabinet 10 can be used, the process proceeds to step S8. In step S8, the master unit 30a determines whether there is a usable cabinet 10 based on the final determination content. If it is determined that there is no usable cabinet 10, the process proceeds to step S18, a card error is displayed on the display unit 46, and the process is terminated.

  On the other hand, if it is determined that there is a usable cabinet 10 in step S8, the process proceeds to step S9, and the unlocking / unlocking device 20 of the cabinet 10 that can be used in the following processing is made unlockable.

  That is, in step S9, the master unit 30a controls the display of the display unit 46 corresponding to the available cabinet 10 to display that it can be used. When a plurality of cabinets 10 are available, the fact that they are available is displayed on all the display units 46 corresponding to the available cabinets 10. Thus, the user can recognize all the available cabinets 10.

  Thereafter, the process proceeds to step S10, and the master unit 30a determines whether or not the switch 42 is operated. Until the switch 42 is operated, the process returns to step S9 to continue the operation of displaying the availability on the display unit 46.

  On the other hand, when the user operates the switch 42 of the cabinet 10 that can be used by the display unit 46 as a clue, it is determined in step S10 that the switch 42 is operated, and the process proceeds to step S11. In step S11, the master unit 30a performs the unlocking operation of the locking / unlocking device 20 of the cabinet 10 in which the switch 42 is operated. Thus, the user can use the cabinet 10 by opening the door or pulling out the drawer. In step S11, reception of operations for the other switches 42 is stopped. That is, for each cabinet 10 except the cabinet 10 unlocked in step S11, the operation reception of the switch 42 is stopped and the locked state is maintained. As a result, the user can selectively use only one of the specified cabinets 10.

  Next, in step S12, it is determined whether or not the use has ended based on the detection result of the sensor 44 or the like. For example, when it is determined that the door or the drawer is closed and the use is finished, the process proceeds to step S13. When the door or the drawer is closed and this state is detected by the sensor 44, the locking / unlocking device 20 performs a locking operation.

  In step S13, the master unit 30a stores the usage history in the RAM 33a. The usage history is information in which specific information, unlocking and locking times (starting and ending times of usage) of the used cabinet 10 are associated with information about the user determined by the card reader 40.

  Thereafter, the process proceeds to step S14, and the card reader 40 that is the reading source is returned to the readable state. In addition, other card readers 40 belonging to the same group are made readable as necessary. Then, the process ends.

  On the other hand, if it is determined in step S2 that the card ID is not registered, the process proceeds to step S15.

  In step S15, it is determined whether or not there is a lost registration. The presence / absence of lost registration is stored in advance in the RAM 33a, for example, and the presence / absence of lost registration is determined based on this prestored information. If it is determined in step S15 that there is a lost registration, the process proceeds to step S16. In step S16, notification is performed using a not-shown notifying means such as a buzzer. This prevents unauthorized use using the ID card 18 registered for loss.

  On the other hand, if it is determined in step S17 that there is no lost registration, the process proceeds to step S17. In step S17, card error processing is performed and the processing is terminated.

  During the above-described series of processing, when another user holds his / her ID card 18 over one of the other readable card readers 40, the card reader 40 moves from the ID card 18 to the card. Read the ID. And the process of said step S1-S18 is performed. That is, the series of processes in steps S1 to S18 are executed in parallel each time the card reader 40 in a readable state performs a card ID reading operation.

  Thereby, while managing the usage history of each user in units of groups of each cabinet 10 assigned to each card reader 40, a plurality of users can simultaneously use the cabinet system for each group.

<D1a: Modified example regarding determination of availability of cabinet>
In step S7, for each cabinet 10, the content of determining whether or not the cabinet 10 is available (step S4) according to the user and the content of determining whether or not the cabinet 10 is available according to the security level (step S6). If at least one of them is available, in other words, the accessible cabinet number obtained in each of steps S4 and S6 is logically ORed for each digit to obtain an accessible cabinet number. May be the final decision. In this case, for example, the cabinet 10 that cannot be used as judged from the accessible cabinet number for each user can be used depending on the time zone.

  Further, step S4 may be omitted. In this case, in step S7, the availability of each cabinet 10 is determined according to the contents determined in step S4, that is, the accessible cabinet number corresponding to the security level specified corresponding to the user.

  According to such a locking / unlocking operation, for example, when the importance of the contents stored in the cabinet 10 changes and the necessity of maintaining the confidentiality of the cabinet 10 changes, the usage for each user is changed. This can be dealt with by changing the setting of the accessible cabinet number (see FIG. 6) for each security level without changing the availability information. For example, when the necessity of maintaining confidentiality for a predetermined cabinet 10 becomes high, the setting is changed so that the corresponding cabinet 10 can be used only in the case of the highest security level 1.

  Here, since such a cabinet system is normally assumed to be used by a large number of users, it is used for a predetermined cabinet 10 rather than changing availability information for a predetermined cabinet 10 for each user. It is easier to change the availability information for each security level with fewer changes.

  For this reason, the availability of the cabinet 10 can be easily changed according to the importance change of the cabinet 10.

  In addition, an accessible cabinet number corresponding to the user is determined based on the read card ID and the user-specific information table (see FIG. 5), and the accessible cabinet number corresponding to the user is identified as described above. Since the availability of each cabinet 10 is finally determined based on both the accessible cabinet number corresponding to the security level, the availability of the storage means is determined in consideration of individual circumstances for the user. it can. For example, it is possible for the chief officer at the installation location of the system to make settings so that all cabinets 10 can be used regardless of the security level, or settings so that all cabinets 10 cannot be used regardless of the security level. is there.

  In this case, based on both the accessible cabinet number corresponding to the user and the accessible cabinet number corresponding to the specified security level, logical operation or the like is performed to determine whether each cabinet 10 can be used. Since the final decision has been made, for example, the amount of information stored in advance can be reduced rather than registering the availability of each cabinet 10 for each user for each security level. Then, the availability of each cabinet 10 can be finally determined by a quick search and a relatively simple calculation process. For this reason, the process from reading the card ID to unlocking can be processed relatively quickly. In addition, the amount of storage means such as RAM can be reduced.

<D1b: Modification regarding unlocking operation>
When returning to step S9 after step S10, the elapsed time from a predetermined reference time such as when the card ID is read or when display of the display unit 46 is started is checked, and if it is determined that the predetermined time has elapsed, The display on the unit 46 may be turned off, and the process related to unlocking may be terminated.

  In addition, after step S13, until the predetermined end condition is satisfied, the other switch 42 resumes the unlocking instruction reception and returns to step S8, and the unlocking operation of the other locking / unlocking device 20 can be performed. You may make it do. The predetermined end condition is determined based on, for example, whether or not an elapsed time has elapsed from a predetermined reference time such as when reading a card ID or starting display on the display unit 46, and the number of cabinets 10 used.

  Thereby, one user can use a plurality of cabinets one by one continuously.

  Further, after step S8, the unlocking / unlocking device 20 of the available cabinet 10 is unlocked without operating the switch 42, and the unlocking / unlocking device 20 of the other cabinet 10 in which one cabinet 10 is actually used. May be locked.

<D2a: Table Rewriting Operation>
In this cabinet system, the security level-specific information table shown in FIG. 6 can be rewritten according to the time zone. For example, when this cabinet system is installed in an office, the number of people is relatively high during daytime work, so the security is set moderately to improve convenience, while the number of people is relatively low at night and during lunch breaks. Therefore, security is more important than convenience, so that operation with strict security can be performed.

  FIG. 9 is a flowchart showing processing for rewriting the security level-specific information table.

  That is, the hourly security level pattern table shown in FIG. 7 is stored in the RAM 33a of the master unit 30a. As shown in step S31, the master unit 30a determines whether or not the current time is the security level pattern change time based on the hourly security level pattern table and the current time measured by the time measuring means. If it is determined that it is the security level pattern change time, the process proceeds to the next step S32.

  In step S32, the master unit 30a selects the security level pattern corresponding to the change time, and stores the stored contents of the RAM 33a so that the security level-specific information table shown in FIG. 6 is replaced with the selected security level pattern. rewrite.

  For example, in the example shown in FIG. 7, the pattern A is rewritten at time “0:00”, the pattern B is rewritten at time “6:00”, the pattern C is rewritten at time “12:00”, and the time “13:00” is rewritten. The pattern D is rewritten to “D”, and the pattern E is rewritten to “18:00”.

  Thereby, the information table classified by security level shown in FIG. 6 is rewritten with different contents (security) for each time zone.

  Here, a table for one week is set and stored in a storage unit (for example, a hard disk device) on the management personal computer 50 side, and the contents of the table for one day are given to the master unit 30a at a predetermined time every day. The configuration in which the hourly security level pattern table shown in FIG. 4 is rewritten has the following advantages. That is, since it is only necessary to store the hourly security level pattern table for one day in the RAM 33a, the storage capacity of the RAM 33a can be made relatively small.

  Further, in this case, if there is no instruction to update the hourly security level pattern table from the management personal computer 50 side, the master unit 30a continuously performs processing based on the previous security level pattern. can do. Thereby, even when a problem occurs on the management personal computer 50 side, the locking and unlocking operation can be continuously performed without causing a big problem.

<D2b: Modification regarding table rewriting operation>
In addition to the configuration in which the security level is rewritten in accordance with the hourly security level pattern table as described above, a configuration in which the security level pattern can be changed in accordance with individual commands through the management personal computer 50 or the like may be adopted. Good.

  For example, when there is an illegal intrusion at the installation location, if an emergency lock request is input through the management personal computer 50 or the like, the pattern may be changed to a pattern having the highest security level.

  Further, for example, when a disaster such as a fire occurs at the installation location, if an emergency release request is input through the management personal computer 50 or the like, the pattern may be changed to a pattern having the lowest security level.

<E: Example of management group>
10 to 12 show examples in which each cabinet is associated with a card reader and grouped.

  First, in FIG. 10, a plurality (here, two) of a plurality (here, five) of cabinets 10 (1), 10 (2), 10 (3), 10 (4), and 10 (5) are provided. An example in which card readers CR1 and CR2 are provided is shown. Further, all cabinets 10 (1), 10 (2), 10 (3), 10 (4), 10 (5) are associated with the card reader CR1, and all cabinets 10 (1) are associated with the card reader CR2. ), 10 (2), 10 (3), 10 (4), and 10 (5) are shown as an example. That is, a case where the group related to the card reader CR1 and the group related to the card reader CR2 are the same is shown.

  In this case, when the user is discriminated through the card reader CR1, the user can select one of the cabinets 10 (1), 10 (2), 10 (3), 10 (4), and 10 (5). Can be used selectively.

  Further, when the user is discriminated through the card reader CR2, the user can select one of the cabinets 10 (1), 10 (2), 10 (3), 10 (4), and 10 (5). One can be used selectively.

  As a result, the user and the use cabinets 10 (1), 10 (2), 10 (3), 10 (4), and 10 (5) by the user can be specified and the history can be managed.

  In the example shown in FIG. 10, since all cabinets 10 (1), 10 (2), 10 (3), 10 (4), and 10 (5) are in one group, only one person can use at the same time. This is not an efficient mode.

  In the example shown in FIG. 11, cabinets 10 (1) and 110 (2) are associated with the card reader CR1, and cabinets 10 (3), 10 (4), and 10 (5) are associated with the card reader CR2. ). That is, the cabinets 10 (1), 10 (2), 10 (3), 10 (4), and 10 (5) are assigned so as not to overlap, and are assigned to a group related to the card reader CR 1 and a group related to the card reader CR 2. A divided example is shown.

  In this case, when the user is discriminated through the card reader CR1, the user can selectively use one of the cabinets 10 (1) and 10 (2).

  In addition, when the user is discriminated through the card reader CR2 regardless of the use state of the cabinets 10 (1) and 10 (2), the user can use the cabinets 10 (3), 10 (4), One of 10 (5) can be selectively used.

  That is, in the example shown in FIG. 11, the group including the cabinets 10 (1) and 10 (2) and the group including the cabinets 10 (3), 10 (4) and 10 (5) can be used simultaneously. . For this reason, it is excellent in utilization efficiency.

  In the example shown in FIG. 12, cabinets 10 (1) and 110 (2) are associated with card reader CR1, and cabinets 10 (3), 10 (4), and 10 (5) are associated with card readers CR2 and CR3. ). That is, the cabinets 10 (1), 10 (2), 10 (3), 10 (4), and 10 (5) are assigned so as not to overlap, and the group related to the card reader CR1 and the card reader CR2 (CR3) are related. An example divided into groups is shown.

  In this case, when the user is discriminated through the card reader CR1, the user can selectively use one of the cabinets 10 (1) and 10 (2).

  When the user is discriminated through the card reader CR2 or CR3, the user can selectively use one of the cabinets 10 (3), 10 (4), and 10 (5). .

  Even in this case, the group including the cabinets 10 (1) and 10 (2) and the group including the cabinets 10 (3), 10 (4) and 10 (5) can be used simultaneously. For this reason, it is excellent in utilization efficiency. In particular, when it is desired to use a group including the cabinets 10 (3), 10 (4), and 10 (5), the card readers CR2 and CR3 can be used.

<F: Specific examples of connecting parts>
13 to 15 are diagrams showing a specific example of the connecting portion. The connection part 14 is formed in the flat bowl-shaped body interposed between the door-type storage part 12 and the drawer-type storage part 16, for example. Here, a description will be given of a configuration example for incorporating various elements constituting the system into the connecting portion 14, in particular, the master unit 30 a or the slave unit 30 b.

  That is, an opening 146 is appropriately formed on the front surface of the connecting portion 14. Here, openings 146 are formed on both sides of the front surface of the connecting portion 14.

  In addition, a pair of rail portions 147 extending from the openings 146 in the depth direction of the connecting portion 14 are formed on the upper surface of the bottom portion of the connecting portion 14, and a pull-out type movable table 148 is movably guided and supported on each rail portion 147. Has been. Among these, the master unit 30a or the slave unit 30b is disposed on the pull-out transfer table 148 on one side (for example, the pull-out transfer table 148 on the left side in FIG. 13). Further, a power supply unit 48 is disposed on the other pull-out type moving table 148 (for example, the right-side pull-out type moving table 148 in FIG. 13) as necessary.

  Further, as described above, the locking / unlocking device 20 is appropriately incorporated in the front surface side substantially central portion of the connecting portion 14.

  In the normal use of the cabinet system, each pull-out type moving table 148 is pushed into the interior of the connecting portion 14. On the other hand, at the time of maintenance of the cabinet system or the like, each pull-out type movable table 148 is pulled out from the connecting portion 14. In this state, maintenance is performed on various components in the connecting portion 14 such as the master unit 30a or the slave unit 30b or the power supply unit 48 placed on the pull-out type moving table 148.

  Further, a panel 150 (160) for closing each opening 146 is attached to the outside of the front surface of the connecting portion 14. The panel 150 (160) incorporates a switch 42, a display unit 46, a cylinder lock unit 22, and a card reader 40 as necessary. The switch 42, the display unit 46, and the card reader 40 are electrically connected to the master unit 30a or the slave unit 30b and the power supply unit 48 through appropriate wiring.

  Then, by attaching the panel 150 (160), the pull-out type moving table 148 cannot be pulled out, and various components in the connecting portion 14 can be protected.

  By the way, in this cabinet system, according to the grouping mode of each cabinet 10, the number of card readers 40 provided in each group, etc., the cabinet 10 incorporating the card reader 40, and the cabinet 10 not incorporating the card reader 40, Are used together.

  Here, a configuration for selectively and replaceably attaching the first panel 150 in which the card reader 40 is incorporated and the second panel 160 in which the card reader is not incorporated to the cabinet 10 as necessary. Will be described.

  FIG. 16A is a plan view showing a state where the first panel is attached to the front surface of the connecting portion of the cabinet, and FIG. 16B is a front view showing the first panel, and FIG. FIG. 17 is a front view showing the second panel, FIG. 17 is a cross-sectional view showing a state where the first panel (or the second panel) is attached to the front surface of the connecting portion of the cabinet, and FIG. It is sectional drawing which shows a state.

  That is, the panel set unit 180 is provided on the front surface of the connecting portion 14 of the cabinet 10. The panel set portion 180 includes a pair of receiving pieces 182 and a pair of screw receiving pieces 184 provided at the peripheral edge of the front opening of the connecting portion 14 (see FIGS. 16A and 17).

  The pair of receiving pieces 182 is provided at each position from both ends of the lower edge of the front opening of the connecting portion 14. Each receiving piece 182 is formed by bending a metal plate material or the like as appropriate, and extends in a substantially horizontal posture so as to protrude from the lower edge of the front opening of the connecting portion 14, and its tip portion Has a shape that rises upward.

  Further, the pair of screw receiving pieces 184 are provided at each position from both ends of the upper edge portion of the front opening of the connecting portion 14. Each screw receiving piece 184 is formed by bending a metal plate material or the like as appropriate, and extends downward from the lower edge of the front opening of the connecting portion 14 and extends in the horizontal direction from the middle thereof. It is formed in the shape to do. Further, a screw hole 184 s is formed at the tip portion of each screw receiving piece 184.

  The 1st panel 150 is formed in the shape which can block | close the front opening part of the connection part 14, and the substantially rectangular plate shape here (refer FIG. 16 (a) and FIG.16 (b)). A cylinder lock portion 22 is attached to a substantially middle portion of the first panel 150, and a switch 42 is attached. In addition, the display unit 46 is attached to a portion from one end portion of the first panel 150, and the card reader 40 is attached to a portion from the other end portion.

  In addition, a pair of screwing pieces 154 are formed at positions corresponding to the pair of screw receiving pieces 184 on the upper edge of the rear surface of the first panel 150, and the lower end of the rear surface of the first panel 150. A pair of engagement pieces 152 is formed at each position corresponding to the pair of receiving pieces 182 on the edge.

  Each screwing piece 154 is a bent part or a resin-molded part of a metal piece, and extends in a direction protruding from the back side of the first panel 150, and has a shape that extends one step down along the way. Is formed. Further, a screw insertion hole 154 s is formed at the tip of each screw stop piece 154.

  Each engagement piece 152 is a bent portion or a resin-molded portion of a metal piece, and extends in a direction protruding from the back side of the first panel 150, and has a shape that extends one step down in the middle. Is formed. The step part dropped one step in the middle is formed to be engageable with the tip part of the receiving piece 182.

  The second panel 160 has the same configuration as the first panel 150 except that the card reader 40 is omitted. The portion to which the card reader 40 is attached is closed and formed on a flat surface. The card reader 40 may be retrofitted to this part.

  The 1st panel 150 (or 2nd panel 160) comprised in this way is selectively attached to the cabinet 10 as follows.

  That is, as shown in FIG. 18, the first panel 150 (or the second panel 160) is tilted, and the pair of engaging pieces 152 are engaged with each other so as to be placed on the pair of receiving pieces 182. In advance, the card reader 40, the display unit 46, the switch 42, and the like are electrically connected to the master unit 30a, the slave unit 30b, and the power supply unit 48 through appropriate wiring. In this state, the upper portion of the first panel 150 (or the second panel 160) is opened at the front surface of the connecting portion 14 so that the engaging portion between the engaging piece 152 and the receiving piece 182 is rotated. Push it into the part. Then, it arrange | positions so that a pair of screwing piece 154 may be piled up on a pair of screw receiving piece 184. FIG. In this state, the screw S is screwed into the screw hole 184s while being inserted into the screw insertion hole 154s from above each screw stop piece 154. Accordingly, the first panel 150 (or the second panel 160) is attached to the connecting portion 14 of the cabinet 10.

  When removing the first panel 150 (or the second panel 160), contrary to the above, the screws S are loosened and removed, and the upper end of the first panel 150 (or the second panel 160) is pulled out. Lift up diagonally. As a result, the engagement between the engagement piece 152 and the receiving piece 182 is also released, and the first panel 150 (or the second panel 160) is removed from the cabinet 10.

  Accordingly, the first panel 150 can be easily replaced with the second panel 160, and conversely, the second panel 160 can be easily replaced with the first panel 150 according to the necessity of adding or reducing the card reader 40.

  Note that the screw head of the screw S is disposed at a position hidden in the closed door portions 121a and 121b, and the screw S cannot be loosened when the door portions 121a and 121b are closed. ing. As a result, it is possible to prevent a situation in which the panel 10 can be illegally removed and disassembled and the cabinet 10 can be used in a state where the cabinet 10 is unavailable, and security can be further improved.

  According to the cabinet system configured as described above, each card reader 40 has a RAM 33a in which a management group table associated with each cabinet 10 is stored in a rewritable manner. Is determined, each cabinet 10 associated with the card reader 40 that has identified the user is specified, and each locking / unlocking device 20 is controlled so that it can be selectively used. . For this reason, a plurality of cabinets 10 can be used simultaneously according to the number of groups of each cabinet 10 according to the association with each card reader 40, and the utilization efficiency of the cabinet system can be improved. In addition, since one user can use one cabinet 10 in each group, it is possible to manage a use history in which each user is associated with the use cabinet 10.

  By the way, in such a cabinet system, it is normal to classify according to the type of stored items. For this reason, the association with the card reader 40 is usually associated with a group according to the type of stored items. In this case, it is usually necessary to allow a larger number of people to access and use the cabinet system at the same time for the storage items that are assumed to be frequently used. For this reason, about the cabinet 10 group which accommodated the storage thing assumed that a usage frequency is high, it divides into a smaller group, and the cabinet 10 group which stored the storage item assumed that a utilization frequency is low becomes a larger group. It is preferable to divide.

  However, when the usage frequency of each stored item changes, it is necessary to change the above grouping according to the usage frequency. In the present embodiment, when the necessity of changing the grouping arises due to such circumstances, in the present embodiment, each cabinet 10 associated with a predetermined card reader 40 is specified based on the management group information table stored in the RAM 33a. Since each locking / unlocking device 20 is controlled, it can be easily dealt with by rewriting the management group information table and adding or deleting the card reader 40 as necessary.

  Further, a panel set unit 180 is provided in the cabinet 10, and a first panel 150 in which the card reader 40 is incorporated in the panel set unit 180 and a second panel 160 in which the card reader 40 is not incorporated are selectively used. , The card reader 40 can be easily incorporated into or removed from any cabinet 10, and flexible grouping can be dealt with.
