  The locker device LU7 includes an electronic lock device 3 used for locking the door and a communication unit 21 for communicating with the control PC 11. The electronic lock device 3 includes a touch panel 15 used for inputting a personal identification number by the user, a lock unit 24 that restricts opening / closing of the door and detects opening / closing of the door, and a control unit 22 that controls the touch panel 15 and the lock unit 24. And a storage unit 23 for storing a password entered by the user.

  The lock unit 24 includes an electronic lock 28 that is locked and unlocked by an electronic operation, and an opening / closing detection unit 29 that detects opening / closing of the door. The touch panel 15 includes an input unit 26 including a plurality of keys operated by a user, and a display 27 that displays numbers assigned one to one to each key. The storage unit 23 stores an unlock number storage unit 38 that stores an unlock number written in a locker use ticket issued by the ticket issuing machine 12, and a password number storage that stores a numeric string input from the input unit 26 as a password. Part 39.

  The control unit 22 is configured by a member having an arithmetic processing function such as a microcomputer or a CPU, and locks and unlocks the user authentication unit 34 that authenticates the user himself / herself by the personal identification number input from the input unit 26 and the electronic lock 28. An unlocking / unlocking instruction unit 33 (unlocking instruction unit) for instructing the lock, an arrangement changing unit 31 for changing the arrangement of the numbers displayed on the display 27, the numbers displayed on the display 27, and the keys of the input unit 26 A decoding unit 32 for decoding the correspondence, and a display erasing unit 35 for erasing the arrangement of numbers displayed on the display 27 before detecting the opening of the door when the opening / closing detection unit 29 detects the opening of the door. .

  As shown in FIG. 3A, the touch panel 15 in FIG. 2 includes a display 27 made of, for example, LEDs or liquid crystal, and an input unit 26 made up of a transparent switch panel superimposed on the display surface of the display 27. The display 27 displays numbers 0 to 9, alphabets C and L, and an input number string. The input unit 26 includes a plurality of keys K1 to K12 arranged in a matrix, and each key K1 to K12 has a function of detecting a pressing operation on the panel surface. “C” is a character indicating an “input value erasing button” for erasing the input number, and “L” is a character indicating a “locking button” for instructing locking of the electronic lock 28.

  As shown in FIG. 3B, the numbers 0 to 9 and the alphabets C and L displayed on the display 27 correspond to the keys K1 to K12 of the input unit 26 on a one-to-one basis. The decoding unit 32 in FIG. 2 decodes the numbers or characters on the display 27 corresponding to the keys K1 to K12 that have detected the pressing operation. For example, when the key K1 in FIG. 3A is pressed, the decoding unit 32 determines that the number “1” on the display 27 has been input. Subsequently, when the key K5, key K9, key K2, and key K6 are pressed down, the decoding unit 32 assumes that the numbers “2”, “3”, “4”, and “5” on the display 27 are input. to decide. Then, the input number string “12345” is displayed on the upper portion of the display 27.

  With reference to Fig.4 (a)-FIG.4 (f), the rule used when changing the arrangement | positioning of the number displayed on the display 27 is demonstrated. The arrangement changing unit 31 in FIG. 2 changes the arrangement of numbers displayed on the display 27 according to, for example, the following rules (1) to (6). The arrangement of numbers changed in accordance with the rules (1) to (6) is called “random arrangement”.

  (1) A number from 0 to 9 is sequentially arranged in any one of two or more directions starting from a specific key in the input unit 26. Next to 9, 0 is arranged. For example, as shown in FIG. 4A, numbers 0 to 9 are sequentially arranged in the right direction or the downward direction with the key K1 arranged in the upper left of the input unit 26 as a starting point (*). The rule that keeps the key position that is the starting point for changing the number arrangement corresponds to the “first rule”.

  (2) The number assigned to the key K1 is incremented by +1 for each predetermined input operation performed by the user. By assigning 0 next to 9, numbers 0 to 9 can be repeatedly assigned to the key K1. The rule for sequentially changing the number assigned to the starting key K1 for each predetermined input operation corresponds to the “second rule”.

  (3) The arrangement direction is changed according to a predetermined number of input operations. For example, it is arranged in the right direction during an odd number of input operations, and is arranged in the downward direction during an even number of input operations. The rule for selecting the direction in which numbers are arranged according to the predetermined number of input operations corresponds to the “third rule”.

  (4) The characters to be changed are numbers from 0 to 9, and the arrangement of the alphabets C and L is not changed. The rule for changing only the arrangement of the numbers corresponds to the “fourth rule”.

  (5) The predetermined number of input operations is cleared when the power is reset.

  (6) The number assigned to the key K1 at the first operation is obtained by adding all the numbers constituting the rocker number printed on the rocker number plate 18 of each locker device LU1, LU2, LU3,. It is a number in the first place of the number.

  For example, in the first input operation of the locker device with the locker number 2104, as shown in FIG. 4B, the arrangement changing unit 31 arranges 7 for the key K1, and 8, 9, Numbers 0 to 6 are arranged in order. In the second input operation of the same locker device, the arrangement changing unit 31 arranges 8 for the key K1 and sequentially numbers 9, 0 to 7 from the key K1, as shown in FIG. 4 (c). Array. Similarly, in the third input operation, the arrangement changing unit 31 arranges 9 for the key K1 and sequentially arranges the numbers 0 to 8 in the right direction from the key K1, as shown in FIG. 4 (d). Then, in the fourth input operation, as shown in FIG. 4E, 0 is arranged on the key K1, and numbers 1 to 9 are arranged in order downward from the key K1.

  As described above, the “random arrangement” is an arrangement of numbers that is changed for each input operation according to the rules (1) to (6), as shown in FIGS. 3 (a) and 3 (b). It can be said that this is an arrangement of numbers with low regularity as compared with a general arrangement of numbers (hereinafter referred to as “normal arrangement”).

  The arrangement changing unit 31 displays “random arrangement” on the display 27 at least when the user sets a password and authenticates the user himself / herself by inputting the password, but FIG. 3A and FIG. The “normal arrangement” as shown in b) may be displayed on the display 27.

  As shown in FIG. 4F, the arrangement changing unit 31 includes, for example, a starting point number counter 41 that counts a number assigned to the starting key K1, and an operation number counter 42 that counts the number of predetermined input operations. A random generation unit 43 that generates an arrangement of numbers displayed on the display 27 according to the rules shown in (1) to (6) based on the number counted by the starting number counter 41 and the number counted by the operation number counter 42; Is provided.

  With reference to FIG. 5, an example of matters described in the locker use ticket issued by the ticket issuing machine 12 will be described. The locker use ticket includes a use date indicating an available date, a locker number of the available locker device, and an unlock number for authenticating a person who purchased the locker use ticket. A person who purchased the locker use ticket can use the locker devices LU1, LU2, LU3,... With the described locker numbers on the date described therein.

  In order to prevent unauthorized use, it is necessary to authenticate the purchaser of a valid locker use ticket by inputting an unlock number from the touch panel 15 when starting use. Therefore, each time the ticket issuing machine 12 issues a locker use ticket, it transmits the information described in the locker use ticket to the control PC 11, and the control PC 11 identifies the locker device LU1 identified by the locker number described in the locker use ticket. , LU2, LU3,..., The unlock number information described in the locker use ticket is transmitted. The locker devices LU1, LU2, LU3,... Store the unlock number data in their own unlock number storage unit 38.

  FIG. 6A shows a state of the locker device LU7 capable of inputting a personal identification number for authenticating the user himself / herself. In this state, from the touch panel 15 on which “Random arrangement” is displayed on the display 27, the user performs an input operation on a password that has already been set. If the user is successfully authenticated by the entered password, the electronic lock 28 is unlocked and the number layout displayed on the touch panel 15 is changed from the “random layout” to the “normal layout”. Is done.

  FIG. 6B shows a state of the locker device LU7 in which the user is successfully authenticated and the door 5 is opened after the electronic lock 28 is unlocked. When the electronic lock 28 is unlocked and the user opens the door 5, the opening / closing detection unit 29 detects the opening of the door 5, and the arrangement of the numbers displayed on the display 27 before the opening of the door 5 is detected. Erase. When the display 27 is made of LED or liquid crystal, the LED or liquid crystal is turned off.

  With reference to FIG.7 and FIG.8, an example of the control method of the rocker apparatus shown in FIG. 1 is demonstrated. 7 and 8 are flowcharts showing a series of processing procedures. First, the part shown in FIG. 7 will be described.

  (A) In step S01, it is monitored whether or not a pressing operation is performed on any key of the input unit 26. When the pressing pressure operation is performed (YES in S01), the process proceeds to step S03, the display 27 is turned on, and the “random arrangement” generated by the arrangement changing unit 31 is displayed on the display 27.

  (B) Proceeding to step S05, it is determined whether or not a password is set in the password storage unit 39. If the password is set (NO in S05), the process proceeds to step S35 in FIG. 8, and if the password is not set (YES in S05), the process proceeds to step S07.

  (C) In step S07, the user waits for the unlocking number to be input by pressing the touch panel 15. For example, the user sequentially inputs the same numeric string as the unlock number written on the locker use ticket shown in FIG. The personal authentication unit 34 determines whether or not the input numeric string matches the unlock number stored in the unlock number storage unit 38. If the number string and the unlock number match (YES in S09), the process proceeds to step S11. If the number string and the unlock number do not match (NO in S09), an error sound is emitted and the process returns to step S07. The user is again prompted to enter the unlock number and waits again for the unlock number to be entered.

  (D) In step S11, a buzzer sound is generated, and the locking / unlocking command unit 33 unlocks the electronic lock 28, and the arrangement changing unit 31 is different from the “random arrangement” displayed in step S03. The number arrangement is changed to “random arrangement” and displayed on the display 27. Specifically, according to the rules shown in (1) to (6), for example, the arrangement of numbers displayed on the display 27 is changed in the order shown in FIGS. 4 (b) to 4 (e).

  (E) Proceeding to step S13, it is determined whether or not the opening / closing detector 29 has detected the opening of the door 5 within a predetermined time after unlocking. If the predetermined time has passed without the opening / closing detection unit 29 detecting the opening of the door 5 (NO in S13 and YES in S15), the process proceeds to S17, the electronic lock 28 is locked, the display 27 is turned off, and S01 is performed. Return to.

  (F) On the other hand, when the opening / closing detection unit 29 detects the opening of the door 5 for a predetermined time (YES in S13), the process proceeds to step S19, and the opening / closing detection unit 29 detects the closing of the door 5 once opened. Wait for that. The user opens the door 5 between S13 and S19 and stores the luggage in the box. When the opening / closing detection unit 29 detects the closing of the door 5 (YES in S19), the process proceeds to step S21, and waits for the user to input a personal identification number for a predetermined time after the door 5 is closed. The user can input an arbitrarily selected 4-digit number string as a personal identification number. When the predetermined time has passed without the user pressing the 4-digit number string and the “locking button” (NO in S23 and YES in S29), the process proceeds to S31, and the locking / unlocking command unit 33 turns the electronic lock 28 on. The display 27 is turned off after locking. Then, it progresses to S33 stage, the use of the said locker apparatus is stopped, and this flowchart is complete | finished.

  (G) On the other hand, if the user depresses the 4-digit number string and the “lock button” during a predetermined time (YES in S23), the process proceeds to step S25, and the input 4-digit number string is secreted. It is stored in the personal identification number storage unit 39 as a number. In step S27, a buzzer sound is emitted, and the locking / unlocking command unit 33 locks the electronic lock 28 and turns off the display 27. Then, it returns to S01 stage.

  Next, the part shown in FIG. 8 will be described.

  (I) If the password is set in the password storage unit 39 in step S05 in FIG. 7 (NO in step S05), the process proceeds to step S35 in FIG. 8, and the user presses down the touch panel 15 to obtain the password. Wait for input. The user is required to input again the same numeric string as the password entered in step S23. Proceeding to step S37, the personal authentication unit 34 determines whether or not the input number string matches the password stored in the password storage unit 39 in step S25.

  (B) If the entered number string matches the password stored in the password storage unit 39 (YES in S37), it means that the user has been successfully authenticated by the password, and the process proceeds to step S39. In addition to making a sound, the locking / unlocking command unit 33 (unlocking instruction unit) unlocks the electronic lock 28, and the arrangement changing unit 31 arranges the numbers displayed on the display 27 at the time of input of the password (S35). Change to a more regular number arrangement. Specifically, the “random arrangement” displayed at the time of inputting the personal identification number (S35) is changed to “normal arrangement”. On the other hand, if the input number string is different from the password stored in the password storage unit 39 (NO in S37), an error sound is generated and the process returns to step S35, and the user presses the touch panel 15 again. And wait for the password to be entered.

  (Ha) Proceeding to step S41, it is determined whether or not the opening / closing detector 29 detects the opening of the door 5 within a predetermined time after unlocking. If the predetermined time has elapsed without the opening / closing detection unit 29 detecting the opening of the door 5 (NO in S41 and YES in S43), the process proceeds to S45, the electronic lock 28 is locked, the display 27 is turned off, and S01 is performed. Return to.

  On the other hand, if the opening / closing detection unit 29 detects the opening of the door 5 during a predetermined time (YES in S41), the process proceeds to step S47, and the display erasing unit 35 turns off the display 27 to turn off the door 5 The arrangement of the numbers displayed on the display 27 before detecting the opening of is deleted. The process proceeds to step S49 and waits for the opening / closing detection unit 29 to detect the closing of the door 5 once opened. The user opens the door 5 between S41 and S49 and takes out the luggage deposited in the box or stores other luggage. When the opening / closing detection unit 29 detects the closing of the door 5 (YES in S49), the process proceeds to step S51, the display 27 is turned on, and the “lock button” is waited for being pressed. At this time, only the “lock button” can be input, and the other keys are not detected.

  (E) Proceeding to step S53, it is determined whether or not the "lock button" has been pressed by the user within a predetermined time after the closing of the door 5 is detected. When the predetermined time has passed without the “lock button” being pressed down by the user (NO in S53 and YES in S57), the process proceeds to step S59, where the lock / unlock command unit 33 locks the electronic lock 28 and displays the display 27. Turns off. Then, it returns to S01 stage.

  (F) On the other hand, if the “lock button” is pressed down by the user for a predetermined time (YES in S53), the process proceeds to step S55, where the lock / unlock command unit 33 locks the electronic lock 28 and displays the display 27. Turns off. Then, it returns to S01 stage.

  Next, an example of a change in the display screen of the display 27 in the flowcharts shown in FIGS. 7 and 8 will be described with reference to FIGS.

  FIG. 9A shows an example of the display screen of the display 27 in S01 to S11 of FIG. A “random arrangement” is displayed on the display 27 by performing a pressing operation on any key of the input unit 26 in step S01 on the display 27 that is turned off (step S03). In this display state, the user inputs the unlock number (for example, 12345) described in the locker use ticket (step S07). If the input unlock number is correct (YES in S09), the electronic lock 28 is unlocked and the number arrangement is changed to another “random array” different from the “random array” displayed in step S03. (Step S11). Specifically, the arrangement of numbers displayed on the display 27 is changed according to the rules shown in (1) to (6).

  FIG. 9B shows an example of the display screen of the display 27 in S21 to S27 of FIG. By performing a pressing operation on any key of the input unit 26 with respect to the display 27 that is turned off, “random arrangement” is displayed on the display 27 and the input of a personal identification number by the user is awaited (S21). Stage). When the user inputs a 4-digit number string (for example, 7964) and presses the “lock button” (YES in S23), the electronic lock 28 is locked and the display 27 is turned off (step S27).

  FIG. 9C shows an example of the display screen of the display 27 in S01 to S05 in FIG. 7 and S35 to S41 and S47 in FIG. A “random arrangement” is displayed on the display 27 by performing a pressing operation on any key of the input unit 26 in step S01 on the display 27 that is turned off (step S03). It waits for the input of the already set password (S35). When the user inputs a 4-digit number string (for example, 7964) and matches the already set personal identification number (YES in S37), the electronic lock 28 is unlocked and "normal arrangement" is displayed on the display 27 ( Step S39). Thereafter, when the opening of the door 5 is detected (YES in S41), the display 27 is turned off, and the arrangement of the numbers displayed on the display 27 is erased (step S47).

  Referring to FIG. 10, in step S03 and step S11 in FIG. 7, the arrangement changing unit 31 generates a “random arrangement” according to the rules (1) to (6) and changes the arrangement of numbers displayed on the display 27. The procedure to do is explained. When the processing operations in FIGS. 7 and 8 are configured as a computer program, the flowchart in FIG. 10 corresponds to a subroutine executed in steps S03 and S11 in FIG.

  (1) In step S101, the number counted by the starting number counter 41 in FIG. Note that, as shown in (6), the starting number counter 41 has an initial value of one of the numbers obtained by adding all the numbers constituting the rocker number printed on the rocker number plate 18 as an initial value. You can set this number.

  (2) In step S103, the number of times counted by the operation number counter 42 of FIG. The operation counter 42 may be set to 0 as an initial value. Further, the execution order of the steps S103 and S101 may be switched.

  (3) Thereafter, the process proceeds to step S105, and it is determined whether or not the number of times counted by the operation number counter 42 is an odd number. If the number is odd (YES in S105), the process proceeds to step S107. If the number is even (NO in S105), the process proceeds to step S109.

  (4) In step S107, the random generation unit 43 assigns the number counted by the starting point number counter 41 to the key K1 that is the starting point, and as shown in FIGS. Numbers are arranged in numerical order to the right and downward. On the other hand, in step S109, the random generation unit 43 assigns the number counted by the starting number counter 41 to the starting key K1, and as shown in FIGS. 4 (c) and 4 (e), the numbers 0 to 9 are assigned. Are arranged in numerical order downward and to the right. Note that 0 is arranged next to 9.

  (5) Thereafter, the process proceeds to step S111, and the number counted by the starting number counter 41 and the number counted by the operation number counter 42 are incremented by +1 respectively. For the numbers counted by the starting point number counter 41, the number after 9 is set to 0.

  As described above, according to the embodiment of the present invention, the following effects can be obtained.

  The arrangement changing unit 31 makes the position of the key K1 as a starting point constant when changing the arrangement of the numbers, so that the user can easily find the regularity determined when changing the arrangement of the numbers. And the arrangement | positioning change part 31 makes it difficult for others to predict the arrangement | sequence of the number at the time of the input operation of a PIN code by a user by changing the number assigned to the key K1 used as the starting point in order. Therefore, according to the electronic lock device and the locker device according to the embodiment of the present invention, it is possible to suppress the leakage of the personal identification number to a third party due to the input operation of the personal identification number, and a desired number to be input by the user Can be easily found.

  Depending on the number of times the operation counter 42 counts, either one of the numbers 0 to 9 is arranged on the right side and the lower side, or the numbers 0 to 9 are arranged on the lower side and the right side is selected. Thereby, since the arrangement direction changes according to the predetermined number of input operations, it is further difficult for others to predict the arrangement of the numbers when the user enters the password.

  In the embodiment of the present invention, “numbers” of 0 to 9 are adopted as an example of “characters” in the present invention. That is, the characters displayed on the display 27 include numbers 0 to 9, and the password is a password that is arbitrarily selected from the numbers 0 to 9. Then, the arrangement changing unit 31 changes the arrangement of 0 to 9 displayed on the display 27. In this way, even in the input operation of the PIN number composed of the numbers 0 to 9, it is possible to suppress the leakage of the PIN number to the third party due to the input operation of the PIN number, and the user should input the desired number This makes it easier to find numbers.

Furthermore, in the embodiment of the present invention, the characters displayed on the display 27 include characters indicating the deletion of the input numbers (input value deletion button) and characters indicating the lock of the electronic lock 28 (locking button). Included, the arrangement changing unit 31 changes only the arrangement of 0 to 9, and does not change the arrangement of the input value deletion button and the locking button. That is, the arrangement changing unit 31 changes the arrangement of characters displayed on the display 27 according to the fourth rule that changes only the arrangement of numbers. Thereby, it is possible to easily find the input value erasing button and the locking button to be input by the user.
(Other embodiments)
As described above, the present invention has been described by way of one embodiment, but it should not be understood that the description and drawings that form part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples and operational techniques will be apparent to those skilled in the art.

  In the embodiment of the present invention, “numbers” of 0 to 9 are adopted as an example of “characters” in the present invention. However, in the “character” in the present invention, a plurality of numbers other than 0 to 9, symbols, alphabets, hiragana, katakana, etc., all of which can constitute information (password) unique to the user when authenticating the user. Is included.

  Although the case where the personal authentication unit 34 authenticates the user and then changes the “random arrangement” displayed on the display 27 when the personal identification number is input to the “normal arrangement” has been described, the present invention is not limited to this. For example, according to the rules shown in (1) to (6), the “random arrangement” displayed on the display 27 at the time of inputting the personal identification number may be changed to another “random arrangement” or after the change. The numbers may be arranged in such a manner that all the numbers displayed on the display 27 are the same number, for example, ten “1” numbers are arranged.

  Both the step S11 in FIG. 7 and the step S39 in FIG. 8 are common in that the unlocking process and the process of changing the number arrangement when the user authentication is successful are common. In the latter case, the personal identification is based on the unlock number specified by the machine 12, and the number arrangement is changed to another “random arrangement” different from the “random arrangement” displayed during the input operation. This is personal authentication using a personal identification number arbitrarily set by the user himself, and is different in that the “random arrangement” is changed to the “normal arrangement”. In this way, by providing a difference in the processing after successful authentication by the unlock number and the personal identification number, the user can easily identify the content of the processing performed by the user, so that the device has high operability for the user. Become. Of course, in order to enhance the effect of visually informing the user that the user has been successfully authenticated and the electronic lock 28 has been unlocked, also in step S11, A process of changing from “random array” to “normal array” may be performed.

  The arrangement changing unit 31 is not limited to changing only the arrangement of 0 to 9 displayed on the display 27, and changes the arrangement of the input value deletion button (C) and the locking button (L) displayed on the display 27 to 0 to 0. It may be changed together with the arrangement of 9. This further makes it difficult for others to predict the arrangement of numbers when the user performs a password input operation.

  In the embodiment of the present invention, the correspondence between the keys K1 to K12 and the numbers and alphabets is shown to the user by superimposing the input unit 26 on the display surface of the display 27 as a transparent switch panel. The invention is not limited to this. For example, without superimposing the input unit 26 on the display surface of the display 27, the input unit 26 and the display 27 are arranged separately on the door, and the correspondence between the keys K1 to K12 and the numbers and alphabets is shown to the user. You can show it.

  Further, the input unit 26 and the display 27 may not be provided on the door 5. For example, a gap may be provided between a plurality of adjacent doors shown in FIG. 1, and the input unit 26 and the display 27 may be provided in the gap.

  Thus, it should be understood that the present invention includes various embodiments and the like not described herein. Therefore, the present invention is limited only by the invention specifying matters according to the scope of claims reasonable from this disclosure.
