Description

  The present invention relates to an identification number verification device that performs a predetermined process when an identification number input from the outside and an identification number stored inside match and match, and stored in such an identification number verification device. The present invention relates to an identification number selection / deletion method for selecting and deleting selected identification numbers, and a computer program for causing a computer to function as an identification number verification device.

  An identification number verification device that performs a predetermined process when an identification number input from the outside and an identification number stored inside match and the two match each other is, for example, an area where only a specific user is permitted to enter and exit It is applied to the entrance / exit management device used for the management of the room. The entrance / exit management device uses a card medium such as an IC (Integrated Circuit) card that stores different identification numbers, that is, IDs (IDentification), for each user, and reads the identification number from the card medium in advance. A usage form is employed in which the ID number of the user who can enter the room is recorded and the electronic lock is unlocked and the room is allowed to enter when the identification number matches.

  In this type of usage, if the user loses the card medium in which his / her identification number is stored, either temporarily or so that a third party cannot pick up and misuse the lost card medium. It is necessary to prohibit reading or verification of the identification number semi-permanently.

  For example, in Patent Document 1, in the cooperation control device and the management system, even when the entry / exit identification information is invalid, the entry / exit management device and the terminal management device are effectively linked. The storage means stores an association state indicating whether the association between the entry / exit identification information and the account identification information is valid or invalid, and this association state is managed by the entry / exit management device. The point that the entry / exit identification information is changed in association with the valid information indicating whether the entry / exit identification information is valid or invalid is described.

  By the way, the entrance / exit management apparatus includes a server computer and a plurality of terminals provided with operation means such as a keyboard and a mouse for inputting characters and numbers, and a large monitor display having a size of 15 inches, 17 inches or more. On the other hand, there is a large-scale device connected to a computer network by a computer network, on the other hand, a stand-alone small-sized device having a single small casing with several switches, for example, There is a small-scale device equipped with a display device such as a 7-segment display, which can display only numerical values of about 4 to 8 digits. The large-scale entrance / exit management device is suitable for entrance / exit management in a large-scale company having hundreds or thousands of employees. On the other hand, a small entrance / exit management device is suitable for entrance / exit management in a small to medium-sized company or the like having about a few to several hundred employees.

  In order for the entry / exit management device to collate the identification number, it is necessary to store the identification number in the entrance / exit management device in advance. In general, for example, identification numbers assigned to employees of companies are often composed of a combination of branch number, department number, employee number, etc. Even for a medium or medium-sized company, the number of digits of the identification number may be about 10 digits or more. For this reason, it is necessary to be able to store, for example, a 10-digit identification number even in a small-scale entrance / exit management device as described above. However, this does not mean that it must have a storage capacity capable of storing all the identification numbers that can be expressed by 10-digit numbers, that is, all 9,999,999,999 identification numbers. For example, it is sufficient to store thousands or tens of thousands of 10-digit identification numbers with a large margin.

  In addition, in the entrance / exit management device, when an employee loses the card medium storing his / her identification number, the identification number assigned to the employee is deleted from the entrance / exit management device, It is possible to prevent the three parties from picking up and misusing the lost card medium.

  When deleting an identification number, it is possible to select one identification number to be deleted from among a number of identification numbers stored in the entry / exit management device by operating the operation means of the entry / exit management device. There is a need to. In this regard, if a ten key can be provided in the entrance / exit management device, an identification number to be deleted can be easily selected by typing a 10-digit identification number using the ten key. However, in the case of a small entrance / exit management device, it is difficult to secure a panel space for arranging the numeric keypad in a small casing, and the installation of the numeric keypad may cause a cost increase that cannot be ignored. At most, it is possible to provide only one changeover switch (or function selection switch) and one decision switch (or execution switch) in addition to an up switch and a down switch for up / down numerical values. In the case of such a small entrance / exit management device, in order to select an identification number to be deleted, the up switch or the down switch must be repeatedly pressed several tens of times or more, and the operability is poor. There is also a method of changing the identification number at a high speed when the up switch or the down switch is pressed for a long time and quickly reaching the identification number to be deleted. However, in the long press operation, if there is not enough time to press the up switch or the down switch, the identification number to be deleted is not reached easily, while if the time to press the up switch or the down switch is too long, Since the identification number to be deleted is exceeded, it is not easy to adjust the long press time, and the operability is not good. In addition, in the case of providing a function for changing the identification number at a high speed by a long press, it is necessary to use a display device with excellent responsiveness in order to display on the display screen how the identification number is changed at a high speed. In the case of a small entrance / exit management device, this becomes a factor of cost increase that cannot be ignored.

  Thus, in a small entrance / exit management device, it is desired to improve the operability at the time of selecting an identification number to be deleted at a low cost. Device, terminal management device, and cooperative control device, only a large-scale system using a network is described, and a selection method with good operability of identification numbers in a stand-alone small-scale entrance / exit management device, There is no description or suggestion of a configuration for realizing it at a low cost.

  Further, although Patent Document 2 describes a wireless medium processing apparatus that can be operated by switching to a stand-alone type, a numeric keypad is used for inputting a registration number and the like. In the case of a management device, it is difficult to secure a panel space for placing the numeric keypad in a small housing, and the problem that the installation of the numeric keypad causes a cost increase that cannot be ignored and how to solve them There is no description or suggestion.

  Hereinafter, an entry / exit management device will be described as an embodiment of the identification number verification device of the present invention, and will be described with reference to the drawings.

(Identification number structure)
FIG. 1 shows a specific example of the structure of an identification number handled in an entrance / exit management device according to an embodiment of the present invention. For example, when a company assigns an identification number to manage employees (employees), even if it is a large company, considering that the number of employees is about tens of thousands, it is used in one company Even if there is a large margin, it is sufficient that there are hundreds of thousands to tens of millions of identification numbers. If this is the case, the maximum number of digits in the identification number should be eight. However, in general, the identification number is not a serial number that simply increases continuously from 1, for example, in the order of employee registration, but has, for example, a structure as shown in FIG.

  In the example shown in FIG. 1, the identification number is 10 digits. Assuming that the number of digits of the identification number is counted from the lower order to the upper order, the first digit of the identification number is a numerical value indicating the number of times the IC card has been reissued and the second digit to the fifth digit. Up to is the employee number (“0561”, “0532”, etc.), and the sixth digit is the management level number (“high” = “1”, “normal” = “0”, “special” = “2”, etc.) The 7th and 8th digits are assigned numbers (“Head Office A” = “03”, “Head Office B” = “04”, “C Branch” = “13”, “D Branch” = “14”. The ninth digit and the tenth digit are unused digits (for example, reserved digits for future use and currently unused, “00”).

  Thus, by including not only the employee number but also the affiliation number in the identification number, it becomes easier to manage the employee. Further, by including a numerical value indicating the number of reissuances of the IC card on which the identification number is recorded in the identification number, it becomes easy to manage the IC card. In addition, by including the management level number in the identification number, the degree of entry restriction can be varied depending on the employee. For example, when the management level number is “special”, entry is permitted regardless of the collation result of the employee number, and when the management level number is “high”, an identification number is added to the entry / exit management device 1. Registration operations can be permitted. The identification number may include other management numbers such as a company number, a department number, and a group number.

(Entry / exit management device)
FIG. 2 shows an entrance / exit management device according to an embodiment of the present invention. In FIG. 2A, an entrance / exit management device 1 according to an embodiment of the present invention is a device that manages entrance / exit into a specific room (or area). The entrance / exit management device 1 collates the identification number read from the non-contact type IC card with the identification number stored in the entrance / exit management device 1, and controls the locking / unlocking of the electronic lock based on the collation result. . The electronic lock is attached to the door of the room or in the vicinity of the door. When the electronic lock is locked, the door cannot be opened, and entry into the room is prohibited, while the electronic lock is unlocked. Can be opened and entry into the room is permitted. Moreover, when an attendant puts an IC card in the IC card input part 8 of the entrance / exit management device 1, the entrance / exit management device 1 collates the identification number and unlocks the electronic lock, and then the entrance person opens the door. When you open the door and close the door after entering the room, immediately lock the electronic lock. As a result, in principle, only one visitor who deceives an IC card is allowed to enter the room. Furthermore, the entrance / exit management device 1 has a work management function for storing employee attendance time, going out time, return time, and work time to manage the work of employees. In other words, the entrance / exit management device 1 is installed at, for example, the entrance / exit of a company's business office to allow employees to enter the business office and non-employees to enter the business office. In addition, the employee's working time can be managed by memorizing the time when the employee went to the office. The entrance / exit management device 1 is a stand-alone type and has a relatively small configuration. That is, the entrance / exit management device 1 does not have a function of constructing a large-scale entrance / exit management system by communicating with, for example, an external server computer and cooperating with the server computer.

  The entrance / exit management device 1 includes a box-shaped casing having a front panel, and is installed, for example, on a wall of a passage near the door. The front panel is provided with a display screen 2, four switches 3, 4, 5, 6, a plurality of LEDs (light emitting diodes) 7, and an IC card input unit 8.

  The display on the display screen 2 is generated by the liquid crystal display device 9 (see FIG. 3) disposed inside the entrance / exit management device 1 and on the back side of the front panel. The liquid crystal display device 9 is provided with a display unit 10 that displays a date, time, identification number, various messages, and the like, and a back side of the display unit 10. And a backlight unit 11 for generating a backlight.

  The backlight unit 11 is configured, for example, by arranging a plurality of green LEDs and a plurality of red LEDs in parallel with the front panel on the back side of the display unit 10. These green LEDs and red LEDs are alternately arranged one by one in the vertical and horizontal directions, for example, green, red, green, and red. For example, a CPU (Central Processing Unit) 21 The light emission is controlled according to the control signal supplied from (see FIG. 3). Thereby, the backlight unit 11 can generate the backlights of a plurality of colors.

  Specifically, a green backlight can be generated by causing only the green LED to emit light. Moreover, a red backlight can be produced | generated by making only red LED light-emit. Furthermore, an orange backlight can be generated by causing the green LED and the red LED to emit light simultaneously. Then, lighting, blinking and extinguishing are controlled for each of the green LED and the red LED, in other words, by changing the light emission timing, the light emission period, the light emission pattern, etc. for each of these LEDs, A light can be generated.

Here, the backlight unit 11 can change the aspect of the backlight in various ways, for example, as follows, depending on the state or operation of the entrance / exit management device 1, for example, by being controlled by the CPU 21.
・ Normal standby: Green backlight on ・ Normal reading of IC card: Green backlight blinking ・ When reading error occurs: Green backlight and orange backlight alternate at intervals of, for example, 0.1 second to 1 second ON / Disallowed card error occurred: Orange backlight lit / Memory full error occurred: Orange backlight blinked / System failure occurred: Red backlight lit Depending on the status or operation of the entrance / exit management device 1 as described above By changing the mode of the backlight, the occurrence of each error can be surely noticed by the visitors performing the operation. The correspondence relationship between the state or operation of the entry / exit management device 1 and the backlight mode can be changed.

  Each of the four switches 3, 4, 5, and 6 is a toggle type key switch that is turned on when the attendee is pressed with a finger and turned off when pressed again with a finger. Located on the underside. These switches 3, 4, 5, and 6 are switches for performing work management in the normal use mode, and correspond to work activity categories, that is, work categories, respectively. Specifically, the four switches 3, 4, 5, and 6 correspond to four work categories of going to work, going out, returning, and leaving work, respectively. That is, the switch 3 marked “Exit” on the front corresponds to work, the switch 4 marked “Out” on the front corresponds to going out, and the switch 5 marked “Return” on the surface returns. Correspondingly, the switch 6 marked “retreat” on the surface corresponds to retirement. When a visitor (employee) puts an IC card in the IC card input unit 8 and then presses the switch 3 corresponding to the attendance, the time at that time is stored in the entrance / exit management device 1 as the attendance time for the employee. Is done. Similarly, when the switch 4 corresponding to going out is pressed after the IC card is picked up, the going-out time is stored, and when the switch 5 corresponding to return is pressed after the picking up the IC card, the time returned from going out is stored, After depressing the IC card, when the switch 6 corresponding to work is pressed, the work time is stored.

  In addition, the four switches 3, 4, 5, and 6 are switched in function assignment in an identification number selection / deletion mode to be described later, and are not used as switches for performing work management as described above. It functions as a switch for selecting and deleting. As shown in FIG. 2B, “Enter”, “Select” marked under “Out”, “Out”, “Return”, “Retreat” on the surface of the switches 3, 4, 5, 6. , “Up” and “Down” indicate functions assigned to the respective switches 3, 4, 5, 6 when the identification number selection deletion is performed. In addition, instead of “Enter”, “Select”, “Up”, “Down”, “>”, “<”, “↑”, “↓”, etc. are provided on the surfaces of the switches 3, 4, 5, 6. A symbol may be written. Specific functions of the respective switches 3, 4, 5, and 6 when performing selection deletion of the identification number will be described later.

(Operation 1 in ID number selection deletion mode)
5 to 7 show the display screen 2, switches 3, 4, 5, 6 and LED 7 in the identification number selection / deletion mode in the entry / exit management device 1. The operation of the entry / exit management device 1 in the identification number selection / deletion mode will now be described with reference to FIGS.

  The memory 22 of the entrance / exit management device 1 stores an identification number array in which the identification numbers of each employee are arranged in ascending order, for example (the identification number array in the identification number array may be in descending order, but in this embodiment, The case of ascending order is taken as an example, and it is desirable that the identification numbers be arranged in ascending order (or descending order) of employee numbers, which will also be described later). When a visitor (employee) puts an IC card on the IC card input unit 8, the entrance / exit management device 1 reads the identification number from the IC card, and in order to find the identification number that matches the read identification number, The identification number array stored in 22 is searched. In addition, when the number of employees increases, the administrator issues an IC card storing a new identification number, and performs a predetermined setting operation on the entrance / exit management device 1 so that the new identification number is obtained. Can be added to the identification number array. On the other hand, if the employee loses the IC card or if the IC card is stolen, the administrator performs a predetermined setting operation on the entrance / exit management device 1 so that the IC card is lost or lost. An identification number that matches the identification number stored in the stolen IC card can be deleted from the identification number array.

  The number of employees of the company that uses the entrance / exit management device 1 is, for example, several hundred to several thousand. In many cases, the number of identification numbers in the identification number array stored in the memory 22 is also large. It becomes. The entrance / exit management device 1 according to the embodiment of the present invention performs selection processing based on a binary search using two switches 5 and 6 provided on the front panel, and selects one identification number from among a large number of identification numbers. The selected one identification number is deleted using the switch 3.

  In the following, the operation of selecting and deleting the identification number of the entry / exit management device 1 will be described with reference to FIGS. 5 to 7. For convenience of explanation, the memory 22 of the entry / exit management device 1 has “0000000001” to “000000000000”. It is assumed that an identification number array in which consecutive identification numbers are arranged in ascending order is stored. Further, it is assumed that the identification number that the administrator desires to delete is “0000000567”.

  FIG. 5A shows an initial screen that is switched to the identification number selection / deletion mode by a predetermined operation. For example, when an administrator places an IC card for setting in which an identification number including a special management level number (for example, “3”) is stored in the IC card input unit 8 of the entrance / exit management device 1, the CPU 21 The identification number is read from the setting IC card via the card input unit 8, and in response to this, the mode switching unit 33 of the CPU 21 switches the mode of the entrance / exit management device 1 from the normal use mode to the setting mode. The setting mode is a mode for performing various settings of the entrance / exit management device 1, and the setting mode includes a plurality of lower modes. When the administrator performs a predetermined operation using any one of the switches 3, 4, 5, 6 of the entry / exit management device 1 switched to the setting mode, the mode switching unit 33 The mode of the leaving management apparatus 1 is switched to the identification number selection / deletion mode. The identification number selection / deletion mode is one of the lower modes of the setting mode, and is a mode for selecting and deleting the identification numbers in the identification number array stored in the memory 22. When the mode of the entry / exit management device 1 is thus switched to the identification number selection / deletion mode, first, the identification number selection unit 34 of the CPU 21 displays the number of identification numbers in the identification number array on the display screen 2. . In this example, since the number of identification numbers in the identification number array is 5000, “5000” is displayed on the display screen 2.

  FIG. 5B and FIG. 5C show screens immediately after the first selection process is performed. That is, when the screen shown in FIG. 5A is displayed, when the administrator presses the switch 4 (“outside”, “Select”), the identification number selection unit 34 follows the first selection process. Then, an identification number at an intermediate position in the identification number array is selected, and the selected identification number is displayed on the display screen 2. Here, in the present embodiment, the intermediate position corresponds to the (n / 2) th in the array when the number n of the identification numbers in the array (identification number array or the specified section) is an even number. This refers to the position, and when n is an odd number, it refers to the position corresponding to the {(n + 1) / 2} th position in the array. In this example, since the number of identification numbers in the identification number array is 5000, the identification number at the intermediate position is the 2500th identification number. Therefore, the identification number to be displayed on the display screen 2 is “00000002500”.

  In addition, since the identification number is 10 digits, the number of numerical values that can be displayed on the display screen 2 at the same time is 8 digits. Therefore, the selected identification number is the lower 8 digits of the identification number. It is divided into the upper two digits, and each part of the divided identification number is displayed on the display screen 2 while being switched at predetermined time intervals (for example, several seconds, preferably about 1 second). In this example, the screen shown in FIG. 5B on which the lower eight digits “0000200” of the selected identification number is displayed and the upper two digits “00” of the selected identification number are displayed. The screen in FIG. 5C is switched at predetermined time intervals. If the identification number has a large number of digits, for example, 20 digits, the identification number is divided into three parts, a lower digit part, a middle digit part, and an upper digit part, and each part is divided at predetermined time intervals. It may be displayed while sequentially switching to. In this case, in order to indicate which part of the identification number the numerical value being displayed corresponds to, the lighting position of the upper triangular mark is moved each time the display is switched. In this embodiment, when displaying the upper digit, the leftmost triangle mark is displayed, and when displaying the lower digit, only the rightmost triangle mark is displayed to facilitate identification of which digit is displayed.

  FIG. 5D shows a screen immediately after the second selection process is performed. That is, when the screen of FIG. 5B or FIG. 5C is displayed, when the administrator presses the switch 6 (“Exit”, “Down”), the identification number selection unit 34 follows this. As the second selection process, the section from the head position to the intermediate position is specified in the identification number array, and the identification number of the intermediate position in the specified section is selected.

Since the identification number selected by the second selection process is also 10 digits, as in the case of the identification number selected by the first selection process, the lower 8 digit part, the upper 2 digit part, The divided parts are displayed on the display screen 2 while being switched at predetermined time intervals. In FIG. 5, the screen on which the lower 8 digits are displayed is shown in FIG. 5D, and the screen on which the upper 2 digits is displayed is omitted. Hereinafter, for such time-division display, only the screen on which the lower 8 digits are displayed is shown.

  FIG. 6A shows a screen immediately after the third selection process is performed. That is, when the screen shown in FIG. 5D is displayed, when the administrator presses the switch 6 (“Retreat”, “Down”), the identification number selection unit 34 selects the third time accordingly. As the process, the section from the head position to the intermediate position is specified in the section specified by the selection process performed immediately before, and the identification number of the intermediate position in the specified section is selected. In this example, since the head position of the section specified by the selection process performed immediately before, that is, the second selection process is the first and the intermediate position is the 1250th, the 1st to 1250th in the identification number array. The first section is identified, and the 625th identification number “0000000625”, which is an intermediate position in the identified section, is selected. The selected identification number is displayed on the display screen 2 in a time-sharing manner as in the case of the identification number selected by the first or second selection process.

  FIG. 6B shows a screen immediately after the fourth selection process is performed. That is, when the screen shown in FIG. 6A is displayed, when the administrator presses the switch 6 (“Retreat”, “Down”), the identification number selection unit 34 performs the fourth selection process. In the section specified by the selection process performed immediately before, the section from the head position to the intermediate position is specified, and the identification number of the intermediate position in the specified section is selected. In this example, since the head position of the section specified by the selection process performed immediately before, ie, the third selection process is the first and the middle position is the 625th, the first to 625 in the identification number array. The section up to the th is specified, and the 313th identification number “0000000313” which is the intermediate position in the specified section is selected. The selected identification number is displayed on the display screen 2 in a time-sharing manner as in the case of the identification number selected by the first to third selection processes.

  FIG. 6C shows a screen immediately after the fifth selection process is performed. That is, when the administrator presses the switch 5 (“Return”, “Up”) while the screen shown in FIG. 6B is displayed, the identification number selection unit 34 performs the fifth selection process as follows: In the section specified by the selection process performed immediately before, the section from the intermediate position to the end position is specified, and the identification number of the intermediate position in the specified section is selected. In this example, since the intermediate position of the section specified by the selection process performed immediately before, ie, the fourth selection process is the 313rd and the end position is the 625th, the 313th to 625 in the identification number array. The first section is identified, and the 469th identification number “000000000469”, which is an intermediate position in the identified section, is selected. The selected identification number is displayed on the display screen 2 in a time-sharing manner as in the case of the identification number selected by the first to fourth selection processes.

  FIG. 6D shows a screen immediately after the sixth selection process is performed. That is, when the screen shown in FIG. 6C is displayed, if the administrator presses the switch 5 ("Return", "Up"), the sixth selection process is performed, and the fifth selection process. The section (469th to 625th) from the intermediate position to the end position is specified in the section (313th to 625th) specified by, and the identification number “000000000547” of the intermediate position (547th) in the specified section is set. Selected and displayed in a time-sharing manner as shown in FIG.

  FIG. 7A shows a screen immediately after the seventh selection process is performed. That is, when the screen shown in FIG. 6D is displayed, if the administrator presses the switch 5 ("Return", "Up"), the seventh selection process is performed, and the sixth selection process is performed. In the section specified by (469th to 625th), the section (547th to 625th) from the intermediate position to the end position is specified, and the identification number “0000000586” of the intermediate position (586th) in the specified section is Selected and displayed in a time-sharing manner as shown in FIG.

  FIG. 7B shows a screen immediately after the eighth selection process is performed. In other words, when the screen shown in FIG. 7A is displayed, if the administrator presses the switch 6 (“Retreat”, “Down”), the eighth selection process is performed, and the seventh selection process is performed. The section (547th to 586th) from the head position to the middle position is identified in the section (547th to 625th) identified by the above, and the identification number “000000000567” of the middle position (567th) in the identified section is Is selected and displayed in a time-sharing manner as shown in FIG. At this point, the identification number that the administrator wishes to delete was selected.

  FIG. 7C and FIG. 7D show screens when the selected identification number is deleted. That is, when the administrator presses the switch 3 (“Out”, “Enter”) while the screen shown in FIG. 7B is displayed, the deletion confirmation display “dELE” is displayed on the display screen 2. Further, when the administrator depresses the switch 3 (“Out”, “Enter”), the identification number deletion unit 35 of the CPU 21 deletes the identification number “0000000567” selected at this time from the identification number array. . Then, the deletion completion display “donE” is displayed on the display screen 2.

  To summarize the above operation for selecting and deleting the identification number, first, the identification number selection unit 34 selects an identification number at an intermediate position in the identification number array (first selection process). Next, when the switch 5 (“Return”, “Up”) is continuously pressed after the first selection process, the identification number selection unit 34 specifies the section from the intermediate position to the end position in the identification number array. Then, the identification number selection unit 34 selects the identification number of the intermediate position in the specified section. On the other hand, when the switch 6 (“Retreat”, “Down”) is continuously operated after the first selection process, the identification number selection unit 34 In the number array, the section from the head position to the intermediate position is specified, and the identification number of the intermediate position in the specified section is selected (second selection process). Next, after the second selection process, each time the switch 5 ("Return", "Up") is operated, the identification number selection unit 34 determines the intermediate position in the section specified by the selection process performed immediately before. The section from the end position to the end position is specified, and the identification number of the intermediate position in the specified section is selected. On the other hand, after the second selection process, each time the switch 6 ("Retreat", "Down") is operated The identification number selection unit 34 identifies the section from the head position to the intermediate position in the section specified by the selection process performed immediately before, and selects the identification number of the intermediate position in the specified section (the third time and Subsequent selection process). After the selection process is performed several times according to the operation of the switches 5 and 6, when the switch 3 (“Out”, “Enter”) is pressed twice, the identification number deletion unit 35 is selected at that time. Delete the identification number from the identification number array.

  The identification number selection process by the identification number selection unit 34 as described above is based on a selection method called binary search or binary search. According to the selection process based on this binary search, a desired single numerical value can be selected from a numerical value of 2 to the X power through a maximum of X selection operations. In the above example, the number of identification numbers is 5000, which is greater than 2 12 (4096) and less than 2 13 (8192), and therefore, a maximum of 13 selection operations (switches 5 and 6 By pressing the button, one desired identification number can be selected. However, in the above example, as shown in FIG. 8, the administrator selects the identification number “000000000567” to be selected from 5000 identification numbers by simply pressing the two switches 5 and 6 eight times. Have been able to. Thus, depending on the identification number to be selected, it can be selected with fewer switch operations than 13 times.

  As described above, according to the entrance / exit management device 1 according to the embodiment of the present invention, one identification number to be deleted from among a large number of identification numbers can be repeated by pressing the two switches 5 and 6 a small number of times. You can select easily and quickly. Therefore, improvement in operability when selecting an identification number to be deleted can be realized at low cost.

  The identification number selection process by the identification number selection unit 34 may be modified as follows. That is, when the switch 5 ("Return", "Up") is continuously pressed after the first selection process, as the second selection process, the section from the position immediately after the intermediate position to the end position in the identification number array Is selected and the identification number of the intermediate position in the specified section is selected. On the other hand, after the first selection process, when the switch 6 (“Retreat”, “Down”) is continuously operated, the second selection process is performed. As an alternative, the section from the head position to the position immediately before the intermediate position in the identification number array may be specified, and the identification number of the intermediate position in the specified section may be selected. In addition, after the second selection process, every time the switch 5 ("Return", "Up") is operated, from the position immediately after the intermediate position to the end position in the section specified by the selection process performed immediately before. And the identification number of the intermediate position in the specified section is selected. On the other hand, after the second selection process, every time the switch 6 ("Retreat", "Down") is operated, The section from the start position to the position immediately before the intermediate position in the section specified by the selection process may be specified, and the identification number of the intermediate position in the specified section may be selected. That is, when the section specified by the selection process performed immediately before is divided into two and the smaller section is specified, the intermediate position selected in the selection process performed immediately before is not included in the smaller section. It may be.

(Operation 2 in ID number selection deletion mode)
FIG. 9 shows a display screen 2, a switch 3, and a switch 3 when selecting an identification number to be deleted by combining the selection process based on binary search and the ascending / descending order selection process in the identification number selection / deletion mode in the entrance / exit management device 1. 4, 5, 6 and LED 7 are shown. Here, the ascending / descending order selection processing is arranged immediately after the identification number selected at the time of pressing the switch in the identification number array every time the switch 5 ("Return", "Up") is pressed. Each time an identification number is selected and the switch 6 ("Retreat", "Down") is pressed, the identification number arranged immediately before the identification number selected at the time of pressing the switch in the identification number array Is the process of selecting. In other words, the ascending / descending order selection processing is performed by shifting the identification number to be selected one by one toward the end position of the identification number array each time the switch 5 ("Return", "Up") is pressed. Each time the switch 6 (“Retreat”, “Down”) is pressed, the identification number to be selected is shifted one by one toward the head position of the identification number array.

  Hereinafter, the operation of selecting an identification number to be deleted by combining the selection process based on the binary search and the ascending / descending order selection process will be described with reference to FIG. Is stored as an identification number array in which identification numbers consecutive from 0000000001 to 000000000000 are arranged in ascending order. Further, it is assumed that the identification number that the administrator desires to delete is 0000000588.

  First, an administrator places an IC card for setting in which an identification number including a special management level number is stored in the IC card input unit 8 of the entrance / exit management device 1, and then switches 3, 4, 5, 6. When a predetermined operation is performed using any one of the switches, the mode of the entry / exit management device 1 is switched to the identification number selection / deletion mode. Immediately after switching to the identification number selection / deletion mode, the number “5000” of identification numbers in the identification number array is displayed on the display screen 2 (see FIG. 5A). Subsequently, when the administrator depresses the switch 4 (“outside”, “Select”), the first selection process is performed and the identification number “00000002500” is selected, and then the switch 6 (“leave”, When “Down”) is pressed, the second selection process is performed and the identification number “00000001250” is selected (see FIGS. 5B to 5D). Subsequently, when the administrator depresses the switch 6 (“Exit”, “Down”), the third selection process is performed to select the identification number “0000000625”, and then the switch 6 (“Exit”, “Down”) is selected. ”), The fourth selection process is performed and the identification number“ 0000000313 ”is selected.

When the identification number “0000000469” is selected and then the switch 5 (“Return”, “Up”) is pressed, the sixth selection process is performed and the identification number “0000000547” is selected (FIG. 6A). To (d)). Subsequently, when the administrator depresses the switch 5 (“Return”, “Up”), the seventh selection process is performed, and the identification number “0000000586” is selected as shown in FIG. 9A. . Thus, as long as the administrator immediately presses the switches 5 and 6 after switching to the identification number selection / deletion mode, the identification number selection unit 34 performs selection processing based on the binary search.

  Subsequently, when the administrator depresses the switch 4 (“Out”, “Select”), and then depresses the switch 5 (“Return”, “Up”), the identification number selection unit 34 in the identification number array The identification number “0000000587” arranged immediately after the identification number “0000000586” selected at the time of pressing the switch is selected. The selected identification number is time-divisionally displayed on the display screen 2 as shown in FIG. 9B (only the screen on which the lower 8 digits are displayed is shown). Further, when the administrator depresses the switch 5 (“Return”, “Up”), the identification number selection unit 34 immediately after the identification number “0000000587” selected at the time of depressing the switch in the identification number array. The arranged identification number “0000000588” is selected. The selected identification number is time-divisionally displayed on the display screen 2 as shown in FIG. 9C (only the screen on which the lower 8 digits are displayed is shown). As described above, when the administrator depresses the switch 4 after switching to the identification number selection deletion mode, the selection process by the identification number selection unit 34 is switched from the selection process based on the binary search to the ascending / descending order selection process.

  When the administrator presses the switch 3 (“Out”, “Enter”) while the screen shown in FIG. 9C is displayed, a deletion confirmation display “dELE” is displayed on the display screen 2, and When the administrator presses the switch 3 (“Out”, “Enter”), the currently selected identification number “0000000588” is deleted from the identification number array, and the deletion completion display “donE” is displayed on the display screen. 2 (see FIGS. 7C and 7D).

  As described above, according to the entry / exit management device 1 according to the embodiment of the present invention, the identification to be deleted is selected by selecting the identification number to be deleted by combining the selection process based on the binary search and the ascending / descending order selection process. The number can be easily selected, and the operability of the selection operation can be further improved.

  As described above, the switching from the selection process based on the binary search to the ascending / descending order selection process may be automatically performed instead of being performed according to the pressing of the switch 4 by the administrator. For example, after the mode of the entrance / exit management device 1 is switched to the identification number selection / deletion mode, the number of executions of the selection process based on the binary search reaches a predetermined number of times, and then the selection process based on the binary search is changed to the ascending / descending order selection process. May be automatically switched to.

(Operation 3 in the ID number selection deletion mode)
Further, the entrance / exit management device 1 operates as follows in the identification number selection / deletion mode. That is, when the switch 5 (“Return”, “Up”) is continuously pressed a plurality of times and then the switch 3 (“Out”, “Enter”) is continuously pressed, or the switch 6 (“Exit”, When the switch 3 (“Out”, “Enter”) is continuously pressed after “Down”) is continuously pressed a plurality of times, the identification number deletion unit 35 displays a predetermined warning message or error message. It is displayed on the screen 2 and waits without shifting to the identification number deletion determination screen until the administrator presses any one of the switches 4, 5 and 6. Instead of or in addition to displaying a predetermined warning message or error message on the display screen 2, the color of the backlight unit 11 may be changed, the LED 7 may be blinked, or a sound is emitted from the buzzer 26. It may be output.

  For example, in the example of the selection process based on the binary search described above, the administrator switches the mode of the entrance / exit management device 1 to the identification number selection / deletion mode, and then switches the switch 4 (“outside”, “Select”) once. After pressing and selecting the identification number “00000002500”, the switch 6 (“Retreat”, “Down”) is continuously pressed three times to select the identification number “0000000313”. Thereafter, if the administrator depresses the switch 3 (“Out”, “Enter”) unlike the above-described example, the identification number deletion unit 35 displays a deletion confirmation display as shown in FIG. Before displaying “dELE” on the display screen 2, a predetermined warning message or error message is displayed on the display screen 2, and the identification number is determined to be deleted until the administrator presses one of the switches 4, 5, 6. Wait without going to the screen. After that, for example, when the administrator performs the same operation again, or when the switch 4 (“out”, “Select”) is pressed once and then the operation of the switches 5 and 6 is performed again, the deletion is executed. Try to go forward.

  As a result, even if there is an identification number that is reached by continuously pressing the same switch, it can be prevented from being accidentally deleted, and an operation error of a person who is not familiar with the operation can be prevented. be able to. In addition, the operation of the switches 5 and 6 at this time may be automatically transferred to the above-described ascending / descending order selection process.

(Replace identification number digits)
In the example shown in FIG. 5 to FIG. 9 described above, for the sake of convenience of explanation, the case where the serial number identification numbers from “0000000001” to “000000000000” are arranged in ascending order in the identification number arrangement stored in the memory 22. Explained as an example. In this example, the last four digits in the identification number correspond to the employee number, and when this identification number is displayed on the display screen 2, the employee number is displayed from the most significant digit of the 7 segment 42 in the lower part of the display screen 2. The administrator can easily see the employee number by looking at the display screen 2. However, in practice, for example, as shown in FIG. 1, the identification number has a complicated structure including the number of reissues of the IC card, a management level number, an affiliation number, and the like. If an identification number having such a complicated structure is displayed on the display screen 2 as it is, it may be difficult to visually recognize the employee number. For example, in the identification number shown in FIG. 1, since employee numbers are arranged from the second digit to the fifth digit, when this identification number is displayed on the display screen 2 as it is, the highest digit of the employee number is the upper row. It is displayed in the lowest digit of the 7 segment 41, and the remaining lower 3 digits of the employee number are displayed in the upper 3 digits of the lower 7 segment 42. As a result, the employee number is divided into upper and lower parts, and it becomes difficult to grasp the employee number separately from other numbers included in the identification number, making it difficult to visually recognize the employee number.

  Further, when performing the selection process based on the binary search as described above and the ascending / descending order selection process, the identification number selection operation is difficult if the identification numbers in the identification number array are not arranged in ascending order (or descending order). Become. For example, if the identification numbers in the identification number array are arranged at random, when the switch 5 or 6 is pressed, the administrator feels that the identification number is selected at random and deleted. This makes it difficult to know which switch operation should select the desired identification number. Therefore, the identification numbers in the identification number array need to be arranged in ascending order (or descending order). Furthermore, if the identification number can be selected using the employee number as a clue, it is convenient for the manager and the selection operation is facilitated. Therefore, it is desirable to arrange the identification numbers in the identification number array in ascending order (or descending order) of the employee numbers. In this regard, in the examples shown in FIGS. 5 to 9 described above, since the identification numbers are serial numbers from “0000000001” to “000000000000”, the identification numbers are arranged in ascending order (or descending order) of the employee numbers. In order to form, the identification numbers need only be sorted in ascending (or descending) order. However, in the case of identification numbers having a complicated structure as shown in FIG. 1, the identification numbers are arranged in ascending or ascending order of employee numbers only by sorting the identification numbers in ascending order (or descending order). An array cannot be formed. For example, in FIG. 1, focusing on the identification number “0013306150” and the identification number “0014305180”, the employee number of the identification number “0013306150” is “0615”, and the employee number of the identification number “0014305180” is “0518”. Therefore, if both identification numbers are arranged in ascending order of employee numbers, the identification number “0014305180” is arranged before the identification number “0013306150”. However, when both identification numbers are arranged in ascending order of the identification numbers, the identification number “0013306150” is arranged before the identification number “0014305180” and is not arranged in the ascending order of the employee numbers.

  Therefore, in the entrance / exit management device 1, the manager can easily see the employee numbers on the display screen 2, and the identification numbers are sorted in ascending order (or descending order) of the employee numbers by sorting the identification numbers. In order to form an arrayed identification number array, a process of exchanging digits of the identification number is performed.

  That is, the array forming unit 36 of the CPU 21 sorts the identification numbers in ascending order after performing the process of replacing the digits of the identification numbers immediately after the mode of the entry / exit management device 1 is switched to the identification number selection / deletion mode, for example. An identification number array is formed or reformed, and this identification number array is stored in the memory 22.

  The process of changing the digit of the identification number is as shown in FIG. 10, for example. That is, before the digit replacement, the first digit of the 10-digit identification number is a numerical value indicating the number of times the IC card is reissued and the second digit to the fifth digit. Is the employee number, the sixth digit is the management level number, the seventh and eighth digits are the affiliation numbers, and the ninth and tenth digits are unused digits, that is, as shown in FIG. It has the same structure as the identification number. The array forming unit 36 replaces the employee number portion with the management level number and the affiliation number in the identification number having such a structure. As a result, after the replacement, the identification number is a numerical value indicating the number of reissues of the IC card in which the identification number is stored, the second digit is the management level number, and from the third digit to the fourth digit Is the affiliation number, the fifth to eighth digits are employee numbers, and the ninth and tenth digits are unused digits.

  The upper 7 segment 41 of the display screen 2 displays the fifth to eighth digits of the numerical value due to the configuration of the liquid crystal display device 9. Therefore, when the replacement identification number is displayed on the display screen 2, the employee number is displayed. It is arranged from the most significant digit of the upper 7 segment 41. Therefore, the administrator can easily visually recognize the employee number on the display screen 2. Further, as long as the ninth digit and the tenth digit of the identification number are unused and “00” is set, when the identification numbers after replacement are sorted, the identification numbers are arranged in ascending order (or descending order) of the employee numbers. The Therefore, it is possible to easily form an identification number array in which the identification numbers are arranged in ascending order (or descending order) of the employee numbers only by sorting the replaced identification numbers. In addition, according to the structure of various identification numbers, you may enable it to set the method of exchanging the digits of an identification number arbitrarily. For example, the digit or range of the part to be replaced may be arbitrarily designated.

  11 and 12 show the display screen 2, the switches 3, 4, 5, 6 and the LED 7 when the selection process is performed for the identification number with the digit changed in the identification number selection / deletion mode of the entry / exit management device 1. Show.

  In the example of FIGS. 11 and 12, for example, when switching to the identification number selection / deletion mode, the identification number stored in the memory 22 is the employee number part from the second digit to the fifth digit and the sixth digit to the fifth digit. The management level number up to 8 digits and the part consisting of the affiliation number are exchanged, and then the exchanged identification numbers are sorted in ascending order to form an identification number array. As a result, for example, the identification numbers of “0004005670”, “0005005860”, “0017012500”, and “00280205001” are changed to “0005670400”, “0005860500”, “0012501700”, and “0025002801”.

  Then, as shown in FIG. 11A, for example, the administrator places an IC card for setting in which an identification number including a special management level number is stored in the IC card input unit 8 of the entrance / exit management device 1. Subsequently, when a predetermined operation is performed using any one of the switches 3, 4, 5, and 6, the mode of the entrance / exit management device 1 is switched to the identification number selection / deletion mode. The number “5000” of identification numbers in the number array is displayed on the display screen 2.

  Subsequently, as shown in FIGS. 11B and 11C, when the administrator presses the switch 4 (“Out”, “Select”), the first selection process is performed. An identification number at an intermediate position in the identification number array is selected, and the selected identification number “0025002801” is displayed on the display screen 2 in a time-sharing manner. That is, the lower 8-digit portion “250002801” and the upper 2-digit portion “00” of the identification number are displayed while being switched. When the lower 8-digit portion “250002801” of the identification number is displayed, the employee number “2500” is just placed in the upper 7 segment 41.

  Subsequently, as shown in FIG. 11 (d), when the administrator presses the switch 6 ("Exit", "Down"), a second selection process is performed, and the first position in the identification number array is performed. To the middle position, the identification number of the middle position in the identified section is selected, and the selected identification number “0012501700” is displayed on the display screen 2 in a time-sharing manner. At this time, the employee number “1250” is arranged in the upper 7 segment 41.

  Subsequently, when the administrator depresses the switch 6 twice and then depresses the switch 5 twice, the third to sixth selection processes are performed, and then the administrator selects the switch 5 (“return”). ”,“ Up ”), the seventh selection process is performed, the section from the intermediate position to the end position is specified in the section specified by the sixth selection process, and the intermediate position in the specified section is specified. The selected identification number “0005860500” is displayed on the display screen 2 in a time-sharing manner. At this time, as shown in FIG. 12A, the employee number “0568” is arranged in the upper 7 segment 41.

  Subsequently, as shown in FIG. 12B, when the administrator presses the switch 6 (“Retreat”, “Down”), the eighth selection process is performed. In the specified section, the section from the head position to the intermediate position is specified, the identification number of the intermediate position in the specified section is selected, and the selected identification number “0005670400” is displayed on the display screen 2 in a time-sharing manner. The At this time, the employee number “0567” is just placed in the upper 7 segment 41.

  Subsequently, when the administrator depresses the switch 3 (“Out”, “Enter”), the deletion confirmation display “dELE” is displayed on the display screen 2, and the administrator further selects the switch 3 (“Out”, “Enter”). ”) Is deleted, the identification number“ 0005670400 ”selected at this point is deleted from the arrangement of the identification numbers, and the deletion completion display“ donE ”is displayed on the display screen 2.

  As described above, by performing the selection process based on the binary search after changing the digits of the identification number, the selection operation can be easily performed using the employee number as a clue, and the operability of the selection operation can be improved. .
