  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 a user-specific information table shown in FIG. 4 and a security level-specific information table shown in FIG. 5, and functions as a storage unit of the management control means. The microcomputer 34 a of the master unit 30 a determines whether or not each cabinet 10 can be used based on the state of the table 42 and the switch 42 and sensor 44 of each cabinet 10, and the determination result is sent to the slave unit 30 b through the communication line 52. To give. The contents of the user-specific information table and the security level-specific information table, and operations based on them will be described in detail later.

  Further, as shown in FIG. 6, the RAM 33a stores an hourly security level pattern table. Then, the master unit 30a updates the security level information table (see FIG. 5) 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. The switch 42 is installed on the front panel of the connecting portion 14 (see FIG. 2). When the user operates the switch 42, a signal indicating that the switch 42 is operated is given to the microcomputer 34a through the input circuit portion 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 light emitting 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 light emitting operation of the light emitting unit 46 is controlled.

  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 light emitting unit 46 are incorporated. In the present embodiment, the card reader 40 is omitted, but a configuration having the card reader 40 may be used. In the description here, the same components as those described above are denoted by the same reference numerals and description thereof is omitted.

  The slave unit 30b includes a microcomputer 34b, a communication circuit unit 35 that relay-connects the microcomputer 34b to the external communication line 52, an input circuit unit 36 that receives external input, and a signal output to the outside. Output circuit unit 37.

  The microcomputer 34b includes a CPU 31b, a ROM 32b, a RAM 33b, and the like, and operates according to a program stored in the ROM 32a. 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 light emitting unit 46, and the like according to a command related to the locking operation or the unlocking operation.

<C4: Description of management PC>
The management personal computer 50 is configured by a general personal computer, and is connected to the master unit 30a and the slave unit 30b through the communication line 52 so as to be communicable.

  For example, the table shown in FIG. 4 can be set or changed through the management personal computer 50.

  As for the table shown in FIG. 6, 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).

However, for the table shown in FIG. 6, 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 for each predetermined period. A history of using each cabinet 10, a history of actual unlocking or locking, and the like are temporarily stored in the RAM 33a. The management personal computer 50 also has a function of collecting the history stored in the RAM 33a or the like at a predetermined timing and storing it in an internal storage means.

<C5: Contents of each table>
The user-specific information table shown in FIG. 4 is a table in which each card ID is associated with a user ID, an accessible cabinet number, and a security level.

  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, for example, the use history and the like by each user is stored and managed in the management personal computer 50.

  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. 4 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. 5 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. 5 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. 6 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. 6, 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 thereafter “12: 0”. 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. 7 is a flowchart showing the locking / unlocking operation in the cabinet system.

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

  In step S1, the master unit 30a refers to the user-specific information table and determines whether the read card ID is registered. If it is determined that the read card ID is registered, the process proceeds to step S2.

  In step S2, the master unit 30a determines an accessible cabinet number (that is, availability information of each cabinet) according to the user based on the read card ID and the user-specific information table (see FIG. 4). .

  Subsequently, in step S3, 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. 4).

  Further, in step S4, the master unit 30a, based on the specified security level and the security level-specific information table (see FIG. 5), the accessible cabinet number corresponding to the security level (usability information on each cabinet). To decide.

  In the following step S5, the master unit 30a uses both the accessible cabinet number determined in step S2 according to the user and the accessible cabinet number determined in step S4 according to the specified security level. Based on the above, whether or not each cabinet 10 can be used is finally determined.

  Here, for each cabinet 10, both the availability determination content of the cabinet 10 according to the user (step S <b> 2) and the availability determination content of the cabinet 10 according to the security level (step S <b> 4) can be used. If it is, it is finally determined that the corresponding cabinet 10 can be used.

  In other words, the accessible cabinet number obtained in step S2 and the accessible cabinet number obtained in step S4 are ANDed for each digit to obtain an accessible cabinet number, which is finally determined. It is said.

  As a specific example, when the accessible cabinet number obtained in step S2 is “101100101101” and the accessible cabinet number obtained in step S4 is “0000011111111”, the finally available accessible cabinet number is determined. Becomes “00000001101”.

  When the final determination of availability for each cabinet 10 is made in step S5, the process proceeds to step S6. In step S6, the master unit 30a determines whether there is an available cabinet 10 based on the final determination content. If it is determined that there is no usable cabinet 10, the process proceeds to step S13, a card error is displayed on the display unit (not shown), and the process is terminated.

  On the other hand, if it is determined that there is a usable cabinet 10 in step S6, the process proceeds to step S7, and the unlocking device 20 of the cabinet 10 that can be used in the following processing is made unlockable.

  That is, in step S7, the master unit 30a blinks the light emitting unit 46 corresponding to the available cabinet 10. When a plurality of cabinets 10 are available, all the light emitting units 46 corresponding to the available cabinets 10 are blinked. Thus, the user can recognize all the available cabinets 10.

  Thereafter, the process proceeds to step S8, and the master unit 30a determines whether or not the switch 42 is operated. Until the switch 42 is operated, the process proceeds to step S7 and the operation of blinking the light emitting unit 46 is repeated.

  On the other hand, if the user operates the switch 42 of the cabinet 10 that can be used by the light emitting unit 46 as a clue, it is determined in step S8 that the switch 42 is operated, and the process proceeds to step S9. In step S9, 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.

  Thereby, the process regarding unlocking is completed. When the user closes the door or pushes in the drawer after the use is completed, this is detected by the sensor 44, and the locking / unlocking device 20 performs the locking operation.

  On the other hand, if it is determined in step S1 that the card ID is not registered, the process proceeds to step S10.

  In step S10, 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 S10 that there is a lost registration, the process proceeds to step S11. In step S11, notification is performed using a notifying means (not shown) 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 S10 that there is no lost registration, the process proceeds to step S12. In step S12, card error processing is performed and the processing is terminated.

<D1a: Modified example regarding determination of availability of cabinet>
In step S5, for each cabinet 10, the content of determining whether to use the cabinet 10 according to the user (step S2) and the details of determining whether the cabinet 10 can be used according to the security level (step S4). When at least one of them is available, in other words, the accessible cabinet number obtained in each of steps S2 and S4 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 S2 may be omitted. In this case, in step S5, the availability of each cabinet 10 is determined according to the content 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 for each security level (see FIG. 5) 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. 4), 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 S7 after step S8, the elapsed time from a predetermined reference time such as when the card ID is read or when the light emitting unit 46 starts blinking is checked, and if it is determined that the predetermined time has elapsed, the light emission is performed. You may make it complete | finish the process regarding unlocking by turning off blinking of the part 46. FIG.

  Moreover, after performing unlocking operation | movement once by step S9, it may return to step S6 and may make another cabinet 10 usable. In this case, for example, the processing related to unlocking may be terminated after a predetermined time has elapsed since the predetermined reference time.

  Furthermore, the processing after it is determined that there is an available cabinet in step S6 in FIG. 7 may be performed in steps S21 to S25 shown in FIG.

  That is, if it is determined in step S6 that there is a usable cabinet 10, the process proceeds to step S21. In step S21, the light emitting units 46 corresponding to the available cabinets 10 are blinked. When a plurality of cabinets 10 are available, all the light emitting units 46 corresponding to the plurality of cabinets 10 are blinked. Thus, the user can recognize the available cabinet 10.

  Thereafter, the process proceeds to step S22, and it is determined whether or not the switch 42 is operated. Until the switch 42 is operated, the process returns to step S21 to repeat the operation of blinking the light emitting unit 46.

    On the other hand, when the user operates the switch 42 of the cabinet 10 that can be used by the light emitting unit 46 as a clue, it is determined in step S22 that there is a switch operation, and the process proceeds to step S23.

  In step S23, the unlocking operation of the locking / unlocking device 20 of the cabinet 10 in which the switch 42 is operated is performed. In addition, the operation acceptance of other switches 42 is stopped. That is, for each cabinet 10 except the cabinet 10 unlocked in step S22, the operation acceptance of the switch 42 is stopped and the locked state is maintained. Thereby, only the single cabinet 10 can be utilized.

  Then, it progresses to step S24 and it is judged whether use of the unlocked cabinet 10 was complete | finished. This determination is made, for example, by determining whether the door is closed or the drawer is pushed based on the output from the sensor 44 provided in each cabinet 10. If it is determined in step S24 that the use of the cabinet 10 has been completed, the process proceeds to the next step S25.

  In step S25, it is determined whether or not a predetermined end condition is satisfied. An example of the termination condition here is an example in which it is determined that the termination condition is satisfied when a predetermined time elapses from a predetermined reference time such as when reading a card ID or when the light emitting unit 46 starts blinking. it can.

  If it is determined in step S25 that the end condition is not satisfied, the process returns to step S21, and the processes in steps S21 to S25 are repeated.

  On the other hand, when it is determined in step S25 that the termination condition is satisfied, the unlocking process is terminated.

  In the processing shown in FIG. 8, when the management control unit receives an unlocking instruction through one switch 42 among a plurality of switches 42 associated with each cabinet 10 as each storage unit, the management control unit receives the instruction. Processing for causing the locking / unlocking device 20 corresponding to the switch 42 to perform the unlocking operation, stopping the reception of the unlocking instruction to the other switches 42 and preventing the other locking / unlocking devices 20 from performing the unlocking operation. It is. When the management control means determines that the use of the cabinet 10 corresponding to the locking / unlocking device 20 is ended based on the output of the sensor 44 after the unlocking operation of the locking / unlocking device 20 is completed, the other switch 42 This is processing for resuming reception of unlocking instructions and enabling the unlocking operation of other locking / unlocking devices 20.

  From another point of view, after one of the plurality of locking / unlocking devices 20 performs the unlocking operation, until the locking / unlocking device 20 performs the locking operation, the other locking / unlocking devices are unlocked. This is a process that prevents the process from being performed.

  Thereby, while one user is using one cabinet 10, it can be made the state where other cabinets 10 do not open. Thereby, the use of only one user using the ID card 18 can be prevented, and the security can be further improved.

  Further, after step S6, the available locking / unlocking device 20 of the cabinet 10 may be unlocked without operating the switch 42. However, the operation of the locking / unlocking device 20 after waiting for the operation of the switch 42 can be unlocked in accordance with the actual use timing of each cabinet 10, so that the security is excellent.

<D2a: Table Rewriting Operation>
Further, in this cabinet system, the security level-specific information table shown in FIG. 5 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. 6 is stored in the RAM 33a of the master unit 30a. As shown in step S9, 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. 5 is replaced with the selected security level pattern. rewrite.

  For example, in the example shown in FIG. 6, 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. 5 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.

  In this case, when 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: Specific example of locking / unlocking device>
Here, an example suitable for adding and retrofitting to an existing cabinet provided with a manual lock that opens and closes using a key as a locking and unlocking device will be described.

  The cabinet 10 has a door-type storage portion 12 in the upper half, a drawer-type storage portion 16 in the lower half, and a connecting portion 14 between them. Locking / unlocking devices 130 and 170, which are specific examples of the locking / unlocking device 20, and a control unit such as a master unit 30a or a slave unit 30b are incorporated in the connecting portion 14.

  The structure which locks and unlocks the door-type storage part 12 among these is demonstrated in detail. FIG. 10 is a front view showing a door-type storage portion and a connecting portion in the upper half of the cabinet.

  The door storage unit 12 has a pair of doors 121a and 121b. A handle 122a is provided on the door 121a on one side. The handle portion 122a is swingable between a posture along the outer surface of the door portion 121a and a posture raised therefrom.

  Moreover, the rotating shaft part 123a is integrated in the door part 121a with the attitude | position along an up-down direction. The rotating shaft portion 123a is configured to rotate within a predetermined range as the handle portion 122a swings.

  Further, claw portions 124a are attached to both ends of the rotating shaft portion 123a. The claw portion 124a is freely changeable in posture so as to be engaged with and disengaged from the engaged portion 125a on the main body side of the door type storage portion 12, and is urged in the engagement direction by an urging means (not shown). . Normally, a hole is formed in the frame on the peripheral side of the main body of the door-type storage unit 12, and the claw portion 124a is inserted into the hole so that the peripheral part of the hole can be freely engaged and disengaged. That is, the peripheral portion of such a hole is the engaged portion 125a.

  And if the door part 121a is closed in the state which closed the door part 121b, the nail | claw part 124a will engage with the said to-be-engaged part 125a, and the both door parts 121a and 121b will be hold | maintained in the closed state. Further, when the handle portion 122a is pulled in this state, the posture is changed in a disengagement direction in which the claw portion 124a disengages through the rotating shaft portion 123a, and the engagement between the claw portion 124a and the engaged portion 125a is changed. The match is released. Thereby, it will be in the state which can open the door parts 121a and 121b.

  The upper locking / unlocking device 130 added to the existing configuration as described above will be described. FIG. 11 is a front view showing the locking / unlocking device, and FIG. 12 is a plan view showing the locking / unlocking device.

  The locking / unlocking device 130 is configured by attaching a swing frame 132 and a solenoid 134 as an actuator to a predetermined bracket 131. The locking / unlocking device 130 also includes a cylinder lock 138.

  The solenoid 134 has a rod portion 134a that is advanced and retracted through a drive circuit (not shown). The operation of the solenoid 134 is controlled by the master unit 30a serving as the management control unit described above.

  The cylinder lock portion 138 has a cam plate portion 138a that is manually rotated by a key (not shown).

  The swing frame 132 is swingably supported via a shaft portion 133. The first receiving portion 132a at the one-side swing end of the swing frame 132 is connected to the tip of the rod portion 134a. Thereby, the rocking | fluctuation flame | frame 132 is rock | fluctuated and driven as the rod part 134a advances / retreats.

  Further, the other-side swing end of the swing frame 132 extends so as to branch into a release restricting portion 132b and a second receiving portion 132c. The release restricting portion 132b extends toward the rear side of the claw portion 124a.

  The swing frame 132 moves between the locked posture (see the posture shown by the solid line in FIG. 12) and the unlocked posture (see the posture shown by the one-dot chain line in FIG. 12) as the rod portion 134a advances and retreats. The posture can be changed. In the locked posture, the release restricting portion 132b is located on the movement locus of the claw portion 124a and restricts the claw portion 124a from changing its posture from the engaged posture to the disengaged posture. In the unlocked posture, the release restricting portion 132b retracts from the movement locus of the claw portion 124a, and allows the claw portion 124a to change its posture from the engaged posture to the disengaged posture. Thereby, the claw part 124a can be used by releasing the engagement as described above and opening the door parts 121a and 121b.

  The second receiving portion 132c is disposed so as to extend toward the peripheral edge of the cam plate portion 138a.

  In addition, when the swing frame 132 is in a locked position, when the cylinder lock portion 138 is manually rotated using the key to rotate the cam plate portion 138a, the cam plate portion 138a is moved to the second position. The receiving part 132c is pushed downward. Then, the swing frame 132 changes its posture to the unlocked posture. Thereby, it is possible to use the claw part 124a in the disengaged state as described above by opening the door parts 121a and 121b manually without driving the solenoid 134.

  Such a locking / unlocking device 130 can be assembled using the space in the existing connecting portion 14, and can be locked / unlocked by an electric drive source using the existing claw portion 124a. Can do.

  Next, the structure which locks and unlocks the drawer | drawing-type storage part 16 among the cabinets 10 is demonstrated in detail. FIG. 13: is a front view which shows the drawer-type storage part and connection part part of the lower half part among cabinets.

  The drawer-type storage unit 16 has a plurality of drawers 161. Each drawer part 161 is drawn out from the drawer body part 162 and is pushed into the drawer body part 162 to be freely housed.

  In addition, a pair of horizontal frames 163 are provided on the upper portion of the drawer main body 162. An intermediate portion in the longitudinal direction of each horizontal frame 163 is swingably connected to an upper portion of the drawer main body 162 and a middle portion from the central portion to each side via a support shaft portion 162a. In addition, one end portions of the pair of horizontal frames 163 are connected to each other in a swingable manner at a substantially central position in the width direction of the drawer main body 162 via a connecting shaft portion 163a. The connecting portion of the pair of horizontal frames 163 is biased upward by biasing means such as a spring, and by moving the connecting portions up and down, the end of each horizontal frame 163 swings up and down. ing.

  Further, vertical frames 165 are arranged on both sides of the drawer main body 162 so as to be movable up and down. The upper end portion of each vertical frame 165 is connected to the outer end portion of each horizontal frame 163, and each vertical frame 165 moves up and down in conjunction with the vertical movement of the outer end portion of each horizontal frame 163.

  Further, each vertical frame 165 is provided with a lock portion 166 corresponding to each drawer portion 161. Then, in conjunction with the vertical movement of each vertical frame 165, the lock portion 166 engages or disengages the corresponding drawer portion 161, and locks the drawer of each drawer portion 161 or releases the lock. .

  The lower locking / unlocking device 170 added to the existing configuration as described above will be described. FIG. 14 is a front view showing the locking / unlocking device, and FIG. 15 is a plan view showing the locking / unlocking device.

  This locking / unlocking device 170 is formed by attaching a swing frame 172 and a solenoid 174 as an actuator to a predetermined bracket 171. The locking / unlocking device 170 also includes a cylinder lock 178.

  The solenoid 174 has a rod portion 174a that is driven back and forth through a drive circuit (not shown). The operation of the solenoid 174 is controlled by the master unit 30a as the management control means.

  The cylinder lock portion 178 has a cam plate portion 178a that is manually rotated by a key (not shown).

  Here, the swing frame 172 is formed in a plate shape extending in a substantially L shape. A substantially central portion (here, a bent portion) of the swing frame 172 is supported through a shaft portion 173 so as to be swingable. A first receiving portion 172a at one end of the swing frame 172 is connected to the tip of the rod portion 174a. Thereby, the rocking | fluctuation flame | frame 172 is rock | fluctuated and driven as the rod part 174a advances / retreats.

  Further, the pressing portion 172 b at the other end of the swing frame 172 is disposed at a position where a vertical movement is applied to the connecting portion of the pair of horizontal frames 163.

  Then, the swinging frame 172 has a first posture (see the posture shown by a solid line in FIG. 15) that presses the connecting portion of the pair of horizontal frames 163 downward as the rod portion 174a advances and retreats. It is possible to change the posture between the second posture (see the posture shown by the one-dot chain line in FIG. 15) that retreats upward and allows the connecting portion to move upward. Thus, as the rod portion 174a advances and retreats, the lock portion 166 is operated from the pair of horizontal frames 163 via the pair of vertical frames 165, so that each of the drawer portions 161 can be pulled out or cannot be pulled out. Can do.

  Further, the cam plate portion 178a of the cylinder lock portion 178 presses the connecting portion of the pair of horizontal frames 163 downward when the cylinder lock portion 178 is manually rotated using a key to rotate the cam plate portion 178a. And a posture that allows the connection portion to retreat upward and allow the connection portion to move upward. Here, a relay frame 168 is provided on the connecting portion of the pair of horizontal frames 163 so as to act up and down (see FIG. 14), and a cam plate portion 178a is disposed above one end of the relay frame 168. Thereby, similarly to the above, each drawer part 161 can be brought into a drawable state or a drawable state by manually rotating the cam plate part 178a without driving the solenoid 174.

  Here, in the present embodiment, by adopting a configuration in which the connecting portion of the pair of horizontal frames 163 is moved up and down via the relay frame 168, the cylinder lock portion 178 is positioned away from the connecting portion of the pair of horizontal frames 163. Can be provided. Here, the cylinder lock portion 138 and the cylinder lock portion 178 are disposed in a close positional relationship, for example, as shown in FIG. Thereby, convenience, design, etc. can be improved.

  In short, the configuration related to these locking / unlocking devices 130 and 170 is, in the existing cabinet 10 having separate storage units 12 and 16 on the upper and lower sides, to the connecting portion 14 thereof, the locking / unlocking devices 130 and 170, the master unit 30a or By incorporating a control unit such as the slave unit 30b, it is possible to electrically control the locking and unlocking of the storage units 12 and 16.

  In addition, the configuration itself that can be easily assembled to the existing cabinet 10 is not limited to the cabinet system that performs the above-described locking / unlocking operation, and various existing cabinets 10 are driven by actuators. This can be applied when adding a configuration for locking and unlocking.

  In addition, in the specific example here, the example in which the separate locking / unlocking devices 130 and 170 are provided above and below and the solenoids 134 and 174 are provided separately is disclosed. These solenoids 134 and 174 may be grasped as one solenoid 21 as a control target and may operate in synchronization, or may be configured to be controlled separately. Moreover, you may make it drive these both locking / unlocking apparatuses 130 and 170 with a single actuator.

  By the way, normally, when assembling the locking / unlocking devices 130, 170, etc. to the cabinet 10 that does not take into account the assembly of the locking / unlocking devices 130, 170, etc., it is necessary to appropriately drill holes in the connecting portion 14. . For example, it is necessary to form holes for allowing the release restricting portion 132b and the pressing portion 172b of the swing frame 172 to pass through in the upper and lower portions of the connecting portion 14. Such drilling is usually very cumbersome.

  In view of this, the holes necessary for assembling the locking / unlocking devices 130 and 170 (preferably including the holes necessary for assembling the electrical components of the master unit 30a or the slave unit 30b and the card reader 40) are connected in advance to the connecting portion 14. It is good to manufacture the cabinet 10 formed in this. Such a cabinet 10 has an advantage that the present system can be constructed relatively easily by incorporating various parts such as the locking / unlocking devices 130 and 170 without drilling later.

<F: Specific examples of connecting parts>
16-17 is a figure which shows a specific example of a connection part. 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 specific configuration example for incorporating various elements constituting the present system into the connecting portion 14, particularly, the master unit 30 a or the slave unit 30 b and the card reader 40.

  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 respective openings 146 in the depth direction of the connecting portion 14 is formed on the upper surface of the bottom portion of the connecting portion 14, and the drawer type mounting 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 right side in FIG. 16). Further, a unit constituting the card reader 40 is disposed on the other drawer type moving table 148 (for example, on the left drawing type moving table 148 in FIG. 16).

  Further, as described above, the locking / unlocking devices 130 and 170 are appropriately incorporated in the substantially central portion on the front side of the connecting portion 14.

  Each master unit 30a or slave unit 30b, the card reader 40, and the locking / unlocking devices 130 and 170 are electrically connected by appropriate wiring.

  In the normal use of the cabinet system, each pull-out type moving table 148 is pushed into the inside 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 master unit 30a or the slave unit 30b, the card reader 40, and the connecting portion 14 placed on the pull-out type moving table 148.

  Further, a panel 151 for closing each opening 146 is attached to the outer front surface of the connecting portion 14. By attaching this panel 151, the pull-out type movable table 148 can not be pulled out, and contact with various components in the connecting portion 14 through each opening 146 is prohibited.

  Further, at least a part of the peripheral edge 152 of the peripheral edge of the panel 151 is in a state where the door part 121a, 121b is closed and the area hidden behind the door part 121a, 121b or the drawer part 161 is closed. It arrange | positions in the area | region hidden inside the drawer part 161 (refer FIG. 17). And the panel 151 is attached to the front surface of the connection part 14 using the screw S at the peripheral edge part 152 (that is, at a position hidden by the door parts 121a, 121b or the drawer part 161).

  That is, the panel 151 cannot be removed when the doors 121a and 121b or the drawer 161 are closed. As a result, it is possible to prevent a situation in which the cabinet 10 can be used by illicitly removing and disassembling the panel 151 in a state where the cabinet 10 is unusable, and security can be further improved.

<Summary>
According to the cabinet system configured as described above and its control method, the security level of the user is specified based on the read card ID and the user-specific information table (see FIG. 4), and the specified security level is determined. Based on the security level-specific information table (see FIG. 5), an accessible cabinet number (usability information on each cabinet) corresponding to the security level is determined. Then, with reference to the accessible cabinet number corresponding to the security level, the availability of each cabinet 10 is finally determined, and the locking and unlocking operations of the locking / unlocking device 20 are controlled based on the determination result. Further, in accordance with the arrival of each time zone, a security level pattern associated with the time zone that has arrived is determined based on the hourly security level pattern table (see FIG. 6), and the security level pattern is determined according to the determined security level pattern. A command is given to update the security level information table (see FIG. 5) to update the security level information table. For this reason, the information table classified by security level is updated sequentially according to the arrival of each time zone, and the availability of the cabinet 10 can be determined at an appropriate security level (degree) according to the time zone. Moreover, since it is possible to cope with the problem by updating the information table for each security level instead of updating the information about each user according to the time zone, the above setting can be easily performed regardless of the number of users. .

<Other variations>
A plurality of master units 30a may be provided. In this case, a plurality of cabinets 10 are divided into a plurality of groups, and one master unit 30a is assigned to each group. Each master unit 30a determines whether or not each group can be used, and is locked and unlocked. The structure to control may be sufficient.

  Further, when each electrical component of the cabinet 10 fails, the predetermined cabinet 10 may be disconnected from the management personal computer and operated. In this case, the operation may be performed by separating the cabinet 10 units, a predetermined group unit, or the like. When separating, it is better to be able to lock and unlock manually using a key.
