The employee ID 3 can store a predetermined number of employee numbers (for example, “12345”) as employee identification information. Then, when the employee ID card 3 is placed over the card reader unit 203 of the mobile terminal 2, an induction current is generated in the communication antenna coil, whereby the CPU operates to perform processing such as reading of the employee number. It has become.
At this time, a predetermined process such as encryption of an employee number may be performed by the CPU.

The locker 5 has a plurality of shelves 501 and stores articles in each shelf 501.
As shown in FIGS. 5 and 6, the shelf 501 of the locker 5 is provided with a door 502 that can be opened and closed on the front surface and a lock 503 for locking the door 502. As a result, each shelf 501 can be locked with a lock 503 to store articles. In this example, the door 502 is a so-called sliding door, and the door 502 slides left and right to open and close.

  The lock 503 has a keyhole into which a cylinder and a key for rotating the cylinder are inserted, and a dead bolt that rotates with the rotation of the cylinder and prevents the door 502 from sliding. In order to lock the lock 503, a key is inserted from the keyhole and rotated in a predetermined direction (for example, counterclockwise). As a result, the opening and closing of the door is restricted by the cylinder rotating and popping out to a position where the dead bolt engages with an engagement hole or the like of the door 502. Also, when unlocking, by inserting a key and rotating it in reverse, the cylinder rotates in reverse and the dead bolt disengages from the engagement hole of the door 502, allowing the door 502 to move freely. .

In the illustrated example, the example in which the locking device is configured by a key and a lock has been described. However, the locking device of the present invention is not limited to this, for example, the key is a card key, and the lock is a card reader that reads the card key. A so-called card key that electrically drives the cylinder by inserting or holding the card key in a card reader may be used.

The lock assist device 4 is a device for restricting the insertion of the key into the keyhole of the lock 503.
As shown in FIGS. 7 and 8, the lock assisting device 4 includes a box-shaped housing 401 having an opening in the upper portion, and the key is inserted into the keyhole of the lock 503 by moving forward and backward from the opening of the housing 401. A regulation bar 402 to regulate, a solenoid 403 that drives the regulation bar 402, a control device 404 that controls energization of the solenoid 403, a battery 405 that supplies power to the control device 404, and a receiving antenna that receives radio waves from the mobile terminal 2 406 and a storage unit lid 407 for storing the battery 405.

  The housing 401 is formed in a hollow box shape, and has an opening 401a at the top. A battery housing portion 401b for housing the battery 405 is formed in the lower portion of the housing 401, and a housing portion 401c for housing the regulation bar 402 and a solenoid 403 for driving the same is formed in the upper portion. Further, two screw holes 401d through which screws for attaching the lock assisting device 4 to the locker 5 are inserted are formed on the attachment surface side of the housing 401 to the locker 5 in the illustrated example. The lock assisting device 4 is fixed to the locker 5 by inserting screws into the screw holes 401 d and screwing them to the locker 5.

The restriction bar 402 is formed in a square plate shape, and the lateral width may be substantially the same as the keyhole of the lock 503 or the width that the key cannot be turned. The restriction bar 402 is in front of the lock 503. By being positioned, the keyhole of the lock 503 is hidden and the key cannot be inserted into the keyhole.
The shape of the restriction bar 402 is not limited to a quadrangle, and may be U or V type in order to increase its strength.
Further, the lower end of the restriction bar 402 is attached to the plunger of the solenoid 403 so that the restriction bar 402 is driven up and down by the solenoid 403.

  The solenoid 403 can advance and retract the plunger and the restriction bar 402 attached thereto by being energized and controlled by the control unit 404. Thus, when energized with the plunger sucked, the solenoid 403 is driven to push out the plunger, and when energized in the pushed state, the plunger is sucked.

  The battery 407 is for supplying power to the control unit 404. The antenna 406 receives radio waves from the mobile terminal 2. When the control unit 404 receives the radio wave received by the antenna 406, the drive signal of the restriction bar 402 is received.

  The control unit 404 performs processing for driving the solenoid 403. The control unit 404 is configured by a microcomputer or the like, and performs control to drive the restriction bar 402 up and down by energizing the solenoid 403 when the antenna 406 receives a drive signal of the restriction bar 402.

Next, the operation of the above system will be described with reference to the drawings.
First, the case where the restriction bar 402 of the lock assisting device 4 is moved upward to cover the keyhole and is hidden will be described. In this state, the shelf 501 is unlocked.
First, an employee who wants to open the shelf 501 of the locker 5 goes to the mobile terminal 2 and holds his / her employee ID card 3 over the card reader unit 23 of the mobile terminal 2. Accordingly, the card reader unit 23 reads the employee number of the employee card 3 and temporarily stores it in the memory (S101). In the reading process, the card reader unit 23 activates the IC of the employee card 3 by electromagnetic induction, and the employee card 3 transmits the employee number stored in the memory to the card reader. Read the employee number.

When the reading is completed, the display control unit 202 of the mobile terminal 2 displays a message for prompting input of the locker number and the shelf number to be opened on the liquid crystal display 21 (S102). As this message, as shown in FIG. 10, a message “Please input the locker number and shelf number to be unlocked”, an input field, and an “ unlock ” button for releasing with the entered contents Then, a “Cancel” button for canceling the process is displayed.

When the locker number and shelf number are input from the numeric keypad 24 according to the display and the “ unlock ” button is selected, the card processing unit 204 of the mobile terminal 2 refers to the employee information storage unit 201 and reads the employee number and the like It is determined whether or not the employee ID information is present and whether or not the employee has the authority to unlock (S103).
This employee ID information check is performed by determining whether or not the read employee number has an employee number that matches the employee number stored in the employee information storage unit 201.
In addition, for example, when the employee with the employee number “12345” requests the opening of the shelf with the shelf number “0001”, the determination as to whether or not there is an authority to unlock the selected shelf 501 is as the authority of the employee. This is done by determining whether the authority to unlock the shelf “0001” is stored in the employee information storage unit 201.
At this time, when the date and time for unlocking is set as the authority (for example, unlocking is possible from 9:00 to 17:00 on weekdays), the date and time conforms to the date and time set for this authority. It is determined whether or not to do.

As a result of the determination, if the employee number read out or the employee is not authorized to unlock the shelf 503, the card processing unit 204 controls the card display control unit 202 to display an error on the display 201 (S104). ), The process is terminated.
Also at this time, the card processing unit 204 stores log data including the date and time when the unlocking operation was performed, the locker number and the shelf number that requested the unlocking, and the employee number in the log data storage unit 200. To do.

  If the employee information read is proper as a result of the determination, the key control unit 203 sends an opening signal to the lock assisting device 4 attached to the shelf 501 of the locker 5 requested to be unlocked. Transmission is performed via the antenna 25 (S105). This release signal includes data representing an unlocking operation instruction, an input locker number, a shelf number, and the like.

The card processing unit 204 stores the release log information in the log data storage unit 200 (S106).
The release log information is data including a date and time when the unlocking operation is performed, a locker number and a shelf number where the unlocking operation is performed, an employee number, and the like.

When receiving the transmitted opening signal via the antenna 406 (S107), the lock assisting device 4 determines whether the received opening signal is an opening signal to the lock assisting device 4 (S108). ). This process is performed by determining whether or not the locker number and the shelf number included in the release signal match the locker number and the shelf number stored in the memory of the lock assisting device 4.
If the result of the check is that they do not match, the received signal is discarded as not being a signal to the lock assisting device 4.

As a result of the check, if it is determined that the signal is an opening signal to the lock assist device 4, the control unit 404 retracts the regulating bar 402 from the lock 503 by energizing the solenoid 403 and sucking the plunger. This state is maintained (S109, S110).
Thereby, as shown in FIG. 5, the keyhole of the lock 503 of the shelf 501 is exposed, and the key can be inserted into the keyhole.
In this state, the employee holding the employee ID card can open the lock by inserting the key he has into the keyhole and turning the lock cylinder.

Then, at a predetermined timing, the card processing unit 204 of the mobile terminal 2 transmits the release log data stored in the employee information storage unit 201 to the work information management server 1 (S111).
Thereby, the work information management server 1 receives the release log data, stores it in the time and attendance information storage unit 12 (S112), and ends the process.

Next, a case where the lock hole of the lock 503 is shielded and hidden by the lock assist device 4 will be described.
First, an employee who locks the shelf 501 of the locker 5 goes to the mobile terminal 2 and holds his / her employee ID card 3 over the card reader unit 23 of the mobile terminal 2. Accordingly, the card reader unit 23 reads the employee number of the employee card 3 and temporarily stores it in the memory (S201). In the reading process, the card reader unit 23 activates the IC of the employee card 3 by electromagnetic induction, and the employee card 3 transmits the employee number stored in the memory to the card reader. Read the employee number.

When the reading is completed, the display control unit 202 of the mobile terminal 2 displays a message prompting the input of the locker number and the shelf number on the liquid crystal display 21 (S202). As the message, as shown in FIG. 12, the "lock" button for performing "locker numbers for locking and enter the shelf number." And message, input field, locking in input contents, A “Cancel” button for canceling the process is displayed.

When the locker number and the shelf number are input from the numeric keypad 24 according to the display, and the “lock” button is selected, the card processing unit 204 of the mobile terminal 2 refers to the employee information storage unit 201 and reads the read employee number and the like. It is determined whether the employee ID information exists and whether the employee has authority (S203).
The employee ID information is checked and whether or not the employee has authority is determined by the same process as the release process.

As a result of the determination, if the employee number is not read or the employee does not have the authority to lock the lock 503 of the shelf, the card processing unit 204 controls the card display control unit 202 to display an error on the display 201 ( S204), the process is terminated.
Also at this time, the card processing unit 204 stores log data including the date and time when the shielding operation instruction is issued, the requested locker number and shelf number, and the employee number in the log data storage unit 200.

If the read employee information is appropriate as a result of the determination, the key control unit 203 transmits a shielding signal to the lock assisting device 4 attached to the shelf 501 of the locker 5 requested for processing. 25 (S205). The shield No. 蔽信, the data representing the shielding operation instruction input locker number, and the like shelf number.

  The card processing unit 204 stores log information in the log data storage unit 200 (S206). The log information is data including the date and time when the shielding instruction operation is performed, the locker number and shelf number where the operation is performed, and the employee number.

Lock the auxiliary apparatus 4 the transmitted shielded signal received via the antenna 406 (S207), the control unit 404, the received barrier No. 蔽信 it is determined whether or not the signal to the lock assisting device 4 ( S208). This processing is performed by determining whether the barrier locker number and shelf number contained in the No. 蔽信 matches the locker number and shelf number that has been stored in the memory of the lock assisting device 4.
If the result of the check is that they do not match, the received signal is discarded as not being a signal to the lock assisting device 4.

As a result of the check, if it is determined that the signal is a shielding signal to the lock assist device 4, the control unit 404 controls the energization of the solenoid 403 to advance the plunger, thereby moving the restriction bar 402 in front of the lock 503. This state is maintained (S209, S210).
As a result, as shown in FIG. 6, the restriction bar 402 is positioned in front of the keyhole of the lock 503 to shield the keyhole, and the key cannot be inserted into the keyhole. Therefore, even if a key is held, the key can be opened because the key cannot be inserted into the keyhole.

Then, the card processing unit 204 of the mobile terminal 2 transmits the log data stored in the employee information storage unit 201 to the work information management server 1 at a predetermined timing (S211).
As a result, the work information management server 1 receives the log data, stores it in the attendance / leaving time storage unit 12 (S212), and ends the process.

Next, a case where employee information is changed will be described.
In this case, when new employee information is registered in the employee information database 11 of the work information management server 1 or when the employee information is changed (for example, change of authority information), the work information management server 1 is connected to the mobile terminal 2. Send to.
The mobile terminal 2 receives new or updated employee information via the communication control unit 205 and stores it in the employee information storage unit 201.
Thereby, when employee ID information is newly added or changed, it can be performed by the process from the work information management server 1.
In addition, employee information can be entered and registered individually from the numeric keypad 24 of the mobile terminal 2.

As described above, according to the system of the above-described embodiment, since the lock assist device 4 only needs to be attached to the lock 503, the lock hole is formed by the restriction bar without modifying or replacing the lock 503 itself. Being shielded makes it virtually impossible to unlock,
Compared with the case where the lock is replaced, only the cost of the lock assist 4 is required, so the cost can be extremely low. This also prevents people other than employees or unauthorized persons from unlocking the shelves unnecessarily.
In addition, since the employee ID card 3 is used as a key by using the attendance management system, it is not necessary to issue a separate key, and the cost can be reduced in this respect.

Further, since the mobile terminal 2 stores the log data, it is possible to record who has tried to unlock and when the mobile terminal 2 has been locked. Therefore, it is possible to specify who of the employees has accessed the documents stored on each shelf.

Also, stores the employee information, etc. to the mobile terminal 2, lock the auxiliary device 4 itself, since it has a structure for driving the regulating bar 402 by a signal from the mobile terminal 4, reducing the size of the lock assisting device 4 The lock assisting device 4 can be attached even where the space such as a locker or a shelf is limited.
Further, since the lock lock assisting device 4 provided with the employee information on the mobile terminal 2 side does not need to have the employee information, even if the employee information is added or changed, the work information management server 1 sends the mobile terminal 2 to the mobile terminal 2 side. It is only necessary to distribute addition / change information to the key, and the processing becomes simpler than distribution to the lock assisting device 4.

  In the above-described system, the example in which each mobile terminal 2 stores employee information has been described, but the present invention is not limited to this. For example, the mobile terminal 2 may not have employee information, but the mobile terminal 2 may inquire employee information to the work information management server 1 every time, and the work information management server 1 may perform authentication processing.

As another example, the employee information storage unit 201 may store information on employees who have entered work at the mobile terminal 2 so that only employees who are working can make unlock requests. In this case, a flag indicating whether or not the employee is working is stored in association with each employee information in the employee information storage unit 201, and only the employee having this flag has the authority to unlock.
As a result, it is possible to prevent an unlocking by using an employee ID that has not been stamped.

  In the above-described embodiment, the example in which the restriction bar 402 is driven by a solenoid or a motor to shield or open the keyhole has been described. However, the restriction bar is moved by hand to shield and open the keyhole. You may do it.

An example of this case is shown in FIG. In the embodiment shown in FIG. 13, a quadrangular prism-like engagement member 412 for sliding the restriction bar 402 by hand is provided on the upper surface of the restriction bar 402.
A hole 411 through which the engaging member 412 is exposed is formed in the longitudinal direction of the upper end surface of the housing 401. The hole 411 is formed from the central portion in the longitudinal direction of the upper end surface of the housing 401 toward the right end in the figure. The upper end portion of the engagement member 412 is exposed from the hole 411.

Further, an engaging portion 413 as shown in FIG. 14 is provided at the tip end portion (the upper end portion in the figure) in the housing 401.
The engaging portion 413 has a tip portion like a key claw. In the normal state, the engaging portion 413 is urged by a spring (not shown) downward in the figure, and upon receiving an opening instruction, the control unit drives the solenoid and the motor to move downward in the figure. The engaging portion 413 is rotated and retracted from the moving path of the restriction bar 402.
In addition, a key claw-like engagement piece 402 a protruding downward is formed at the lower end portion of the restriction bar 402. When the restriction bar 402 is pulled upward, the engagement piece 402a is engaged with the engagement portion 413 so that the movement of the restriction bar 402 is restricted.

  In the lock assist device configured as described above, when the keyhole is shielded, the engaging member 412 is manually moved, and the restriction bar 402 is pulled out until the keyhole is hidden. As a result, as the engaging piece 402a of the restriction bar 402 moves upward in the drawing, the engaging portion 413 temporarily moves upward against a spring or the like (not shown) by hitting the engaging portion 413 (the upper end portion in the drawing). When the engagement piece 402a exceeds the engagement portion 413, the engagement portion 413 is exposed again on the moving path of the regulation bar 402 by the biasing force of the spring, and the engagement piece 402a Engage. As a result, the movement of the restriction bar 402 is restricted while remaining at the position where the keyhole is shielded.

  In order to expose the keyhole from this state, a solenoid or a motor is driven by an opening signal from the mobile terminal 2 so that the engaging portion 413 rotates in the downward direction in the figure and retracts from the movement path of the regulation bar 402. . As a result, the engagement with the engagement piece 402a is released, and the regulation bar 402 falls due to its own weight, and the keyhole is exposed.

Note that the shapes of the engagement pieces and the engagement portions are not limited to the shapes shown in FIG. 14 and may be the shapes shown in FIG.
In the example shown in FIG. 15, the engagement pieces 421a and 421b having the engagement holes 421 on the housing side and the recesses having a cross-sectional arc shape formed on the inner side of the front end are overlapped facing each other, so Is formed. These engagement pieces 421a and 421b are urged by a spring 422 in a direction to attract each other.
A release bar 423 for releasing the engagement pieces 421a and 421b against the urging force of the spring 422 is disposed between the engagement pieces 421a and 421b. The release bar 423 is configured so that its diameter increases as it is inserted (the diameter gradually increases toward the right side in the figure). The release bar 423 is driven by a solenoid or a motor (not shown), moves to the left side in the figure, and advances between the engagement pieces 421a and 421b to release the engagement with the protrusion 420. ing.
Further, a hemispherical protrusion 420 is formed at the tip of the regulation bar 402, and this protrusion 420 is engaged with the engagement hole 421.

In the apparatus configured as described above, when the restriction bar 2 is pulled out, the engagement piece 402a engages with the engagement hole 421, so that the movement of the restriction bar 2 is locked. To move the regulating bar 402 from this state, the release bar 423 by the opening signal from the mobile terminal 2, the engaging piece against the biasing force of the spring 422 421a, enters the overlapping portion of the 421b. As a result, a gap between the engagement pieces 421a and 421b is opened, the engagement between the engagement pieces 421a and 421b and the protrusion 420 is released, and the protrusion 420 comes out. As a result, the regulation bar 402 can be freely moved by hand.

In the above-described embodiment, an example in which the restriction bar is moved has been described. However, the cover itself covering the upper surface of the housing may be moved.
FIG. 16 shows an example in which the keyhole is shielded / opened by moving the cover.
In FIG. 16, the key assisting device 600 includes a housing 601 and a cover 607.
The housing 601 is provided with a control unit 604 and a battery 605 for driving the control unit 604, and the cover 607 is driven by energizing the control unit 604.
Also, guide grooves 608 for moving the cover 607 are formed in a straight line at both ends in the longitudinal direction of the housing 601. As shown in FIG. 17, the guide groove 608 is formed such that the lower end portion is wider than the upper end opening. The rail 607a extending downward from the lower portion of the cover 607 is engaged so that the cover 607 can move along the guide groove 608.

The cover 607 has an elliptical shape extending in the vertical direction in FIG. And LED610,611 is attached to the upper end surface, and it is electrically connected with the control part 604 by the wiring which is not shown in figure. The LED 610 is a red LED indicating a locked state. When the LED 610 is lit in red, the cover 607 is in an unlocked state and the cover 607 can be moved by hand. When the LED 607 is off, the cover 607 is locked and cannot be moved manually.
The LED 611 is used to indicate a battery exhaustion warning. The LED 611 is turned off in a normal state, but the LED 605 is turned on when the control unit 604 determines that the voltage of the battery 605 is lower than the reference voltage. To inform you that the battery is almost exhausted. As a result, it is possible to prevent the cover 607 from being opened due to battery exhaustion.

Further, an engagement hole 608 shown in FIG. 18 is formed in the lower end portion of the cover 607, and an engagement protrusion 609 that engages with the engagement hole 608 is formed on the housing side.
The engagement hole 608 has a size with which the engagement protrusion 609 fits. In the normal state, the engagement protrusion 609 is biased upward by a spring (not shown). Further, the engagement protrusion 609 is driven by a motor, a solenoid, or the like (not shown) so that it can be withdrawn and retracted on the housing against the biasing force of the spring.
The cover 607 is completely pulled out, and the engagement protrusion 609 fits into the engagement hole 608 so that the movement of the cover 607 can be restricted.

In the above-described embodiment, when the keyhole of the lock 503 is shielded, the cover 607 is lifted and moved by hand as shown in FIG. 16A to a position where the keyhole of the lock 503 is hidden. When the cover 607 moves to this state, the engagement protrusion 609 engages with the engagement hole 612 by the biasing force of the spring, and the movement of the cover 607 is restricted. As a result, the keyhole of the lock 503 is shielded.

Further, from this state, the control unit drives the motor or the like by the release signal from the mobile terminal 2 and pulls the engagement protrusion 609 into the housing against the urging force of the spring, thereby engaging with the engagement hole 612. Release the match.
Thus, the cover 607 can be moved by having due to its own weight, or by hand, that the keyhole of the lock 503, as shown by the broken line is moved to a position to be exposed in FIG. 16 (b), the lock key 503 It can be inserted into the keyhole and locked and unlocked.

Thus, according to the above-described embodiment, there is no need to provide a regulating bar, and the keyhole of the lock 503 can be shielded or opened only by the cover 607, so that the number of parts can be reduced, In addition, the thickness of the device can be reduced and the size can be reduced by the amount that the restriction bar is not provided, and the device can be attached to keyholes at any place such as a shelf or a safe.
In addition, since the cover 607 is moved manually by hand, a mechanism such as a gear for moving the cover 607 is unnecessary, the number of parts can be reduced, the cost can be reduced, and the battery consumption can be reduced. Battery life can be extended.

  Further, since the LED 611 represents the battery exhaustion state, the battery exhaustion state can be understood at a glance, so that it is possible to prevent the battery from being exhausted when the cover 607 is closed.

In addition, as an engagement protrusion, a form as shown in FIG. 19 may be sufficient.
In the example shown in FIG. 19, a long hole is provided in the short direction of the housing, and a plate-like engagement protrusion 616 is disposed in the long hole. The engagement protrusion 616 is driven up and down by a motor 614 and a cam 615 attached to the rotation shaft of the motor 614. The engaging protrusion 616 is biased upward by a spring (not shown), and the motor 614 pulls down the engaging protrusion 616 against the biasing force of the spring.
Further, an engagement hole 607 a that engages with the engagement protrusion 616 is formed on one end side (the left end portion in the drawing) of the back surface of the cover 607. The engagement hole 607a is formed to be long in the lateral direction in accordance with the shape of the engagement protrusion 616, and the engagement protrusion 616 is engaged with the engagement hole 607a.

As described above, even in the configuration shown in FIG. 19, the cover 607 is manually moved and pulled out, and moved to a position where the key hole is shielded, so that the engagement protrusion 616 engages with the engagement hole 607a, and the cover The movement of 607 can be restricted.
Further, in this state, the motor 614 rotates by the release signal from the mobile terminal 2, and the engagement protrusion 616 is pulled into the housing against the biasing force of the spring. Thereby, the engagement with the engagement hole 607a is released, and the cover 607 is freely movable. As a result, the cover 607 is moved from a position where the keyhole is blocked by its own weight or by its own weight, so that the keyhole is opened.
Thus, the same effect as that of the above-described embodiment can be obtained even by the configuration shown in FIG.

Note that the guide groove 608 may be provided not only at the upper end of the housing 601 but also in a straight line on both side surfaces of the housing 601 as shown in FIG. In this case, as shown in FIG. 20B, rails 617a projecting toward the center side are provided on both inner side surfaces of the cover 617, and the rails 617a are engaged with the guide grooves 608.
