Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a locking management device for a pinball game machine, and in particular, a device for unlocking a door frame including a glass frame and a front frame using a mechanical lock and key. The present invention relates to a locking management device for a pinball game machine which is electrically locked in place of or in addition to locking.

[Prior Art] As is well known, in a pinball game played using pachinko balls such as a pachinko game machine or a coin game machine, there is a front frame (so-called wooden frame) and a glass frame (so-called metal frame) on the front side. ) are installed so that they can be opened and closed. This glass frame is opened during business hours when a ball gets caught on a nail formed on a game board or when a game machine breaks down and needs to be repaired. Furthermore, after closing, the glass frame is opened to adjust the nails. The front frame is constructed by attaching a glass frame so as to be openable and closable and integrally supporting the game board. This front frame is attached to the island frame to which the pinball game machine is mounted so that it can be opened and closed in order to repair various mechanisms disposed on the back side of the game board when they break down. In order to open and close such a glass frame and front frame, a keyhole has conventionally been formed in a part of the front frame. In connection with the keyhole, a locking mechanism for locking or unlocking the front frame and a locking mechanism for locking or unlocking the glass frame were built-in. When opening the glass frame and the front frame, either one was opened by inserting a common key into the keyhole and rotating the key in different directions or angles.

[Means for Solving the Problem] By the way, in amusement arcades, in order to quickly deal with abnormal situations such as a ball getting caught on a nail or a machine malfunctioning, employees of the amusement arcade are required to carry keys with them. ing. However, if an employee loses the key and the key is thrown away by a player,
There have been cases where a player illegally opens the front frame or glass frame with the key, and engages in illegal games such as forcibly opening the Yakumono or adjusting the nails for his own advantage. Therefore, one method to prevent such illegal games is to have a different type of key for each pinball game machine on an island basis among all the pinball game machines in the amusement park, and even if the key is There is a way to prevent people from knowing which machine the key belongs to even if the key is lost. However, in the case of this method, the number of types of keys to be managed in one gaming hall increases, and there may be cases where the keys cannot be managed sufficiently. In addition, the key required to unlock a certain pinball game machine must be searched among a large number of keys, and it takes time to find the key, which can be frustrating for the player. arise. Therefore, it is not possible to have too many types of keys in gaming facilities where quick unlocking operations are required, and it is necessary to configure the machines so that one type of key can unlock a large number of pinball gaming machines. There isn't. On the other hand, if a player finds a lost key and finds out which machine it belongs to, there is a risk of illegal gaming, so in order to completely prevent this risk, This method has the disadvantage that multiple locks corresponding to the lost key must be replaced, making the work extremely expensive, troublesome, and complicated.

Therefore, an object of the present invention is to prevent the player from opening the door frame even if the player loses the key to open the door frame of the pinball game machine and throws away the lost key. To prevent fraudulent games at a low cost and with simple work, and to enable an attendant at a game parlor to easily discover the occurrence of a fraudulent act in which the player illegally opens a door frame.

[Means for Solving the Problems] A locking management device for a pinball game machine according to the present invention includes: a pinball game machine equipped with a door frame that can be freely opened; a set information storage carrier; an information input means provided at a position related to the front surface of the pinball game machine for inputting the information set in the information storage carrier; and an information input means for inputting the information set in the information storage carrier; The pinball game machine includes a management device that determines and manages the locked state of the door frame, and the pinball game machine includes: a locking mechanism that is provided in association with the door frame and locks the door frame in a closed state; electrical opening enabling means operating on the mechanism to switch the door frame from a non-openable state to an openable state, the management device being correlated to an authorization code set on the information storage carrier; a first storage means for presetting and storing a permission code; a second storage means for temporarily storing a permission code set on the information storage carrier when the information storage carrier is lost; and a second storage means for storing the permission code set in the information storage carrier in advance; When a permission code is read from the information storage carrier, the permission code is compared with the permission code set and stored in the first storage means, and it is determined that the two permission codes have a predetermined relationship. When the electrical opening enabling means is activated and it is determined that the two permission codes do not have a predetermined relationship, the permission code read from the information storage carrier and the permission code temporarily stored in the second storage means are an arithmetic processing means that determines that the information storage carrier is lost when it is determined that the two acceptance codes match by comparison; and an arithmetic processing means that determines that the information storage carrier is the lost information storage carrier. The present invention is characterized in that it includes a notification means for notifying that the lost information storage carrier is being used illegally when the information storage carrier is lost.

[Operation] In this invention, the permission code stored in the information storage carrier can be inputted from the information input means, and the input permission code and the permission code preset and stored in the first storage means are subjected to arithmetic processing. Comparative judgment is made by means. Then, when it is determined that both permission codes have a predetermined relationship, the electric opening enabling means is activated to control the door frame of the pinball game machine to a state where the door frame can be opened. On the other hand, when the information storage carrier is lost, the permission code set on the information storage carrier is temporarily stored in the second storage means. If the arithmetic processing means determines that the two permission codes do not have a predetermined relationship, the permission code read from the information storage carrier and the permission code temporarily stored in the second storage means are Compare and judge. When it is determined that the two permission codes match, the notification means notifies the user that unauthorized use of the lost information storage carrier has occurred.

In other words, even if you lose the information storage carrier that allows you to open the door frame of the pinball game machine, if the permission code stored in the information storage carrier is rewritable, it will not be lost. The permission code and the permission code stored in the first storage means are rewritten, and if the permission code stored in the information storage carrier cannot be rewritten, the permission code stored in the first storage means is rewritten. Rewrite only the code,
Unauthorized gaming can be prevented by newly preparing and using an information storage carrier having a corresponding permission code. Moreover, when the lost information storage carrier is used, it becomes possible to notify that fact by the notification means, and the staff at the game parlor can easily discover that the lost information storage carrier has been used.

does not store any information. In addition, when using the same permission code continuously for a certain period,
If the permission code stored at the previous address is the same as the permission code input on that day, the date of that day is updated in the part corresponding to the address in the storage area 912 that indicates the end date of use of the same permission code. written to. Furthermore, the permission code written in the lost electronic key unit is written into each address of the storage area 920.

FIG. 10 shows a management device 6 that is a feature of this invention.
1 is a flowchart for explaining the operation of 0.

Next, the operation for setting the permission code will be described with reference to FIGS. 6 to 10. The setting input of the permission code is performed by switching the key switch 62 to the ON position, and then inputting date information and the permission code as described below. In other words, before the game hall opens, press the numeric key 6.
30 and the date key 631 to input the date information of the day, and then operate the numerical keys 630 and the permission code key 632 to input the permission code. Now, assume that date information is input by operating the numerical keys 630. In step 1, the CPU 81 constantly performs an operation to determine whether or not any key input is made. When it is determined that any key has been input, it is determined in step 2 whether the key switch 62 has been switched to the LOCK position. This is because if the key switch 62 is switched to the LOCK position, input via the keyboard 63 is prohibited, so the following operations are prohibited. Here, since the key switch 62 is set to the ON position, it is determined in step 3 that the currently operated key is the numeric key 630. Subsequently, in step 4, the contents of the register 91 are shifted to the upper digit by one digit, and the input numerical information is stored in the least significant digit. In step 5, the numerical information is displayed on the numerical display 66 as required. Thereafter, in step 6, the counter 95
The content of is incremented by 1, and the process returns to step 1 of waiting for key input. In this way, number key 6
Each time 30 is operated, the numerical information input by operating the numerical key 630 is stored in the register 91.

Next, the date key 631 is pressed to specify that the numerical information input by operating the numerical key 630 is year, month, day (or date) information.
In response to this, after the determination operations in steps 1 to 3, it is determined in step 7 that the date key 631 has been pressed. Subsequently, in step 8, flags F2 and F3 are reset, and flag F1
is set. In step 9, the contents of register 91 are transferred to register 93. In step 10, this date information is displayed on the numerical display 66.
is displayed, and the lamp built into the date key 631 is lit. This informs that the numerical information displayed on the numerical display 66 is year, month, and day information. Subsequently, in step 11, the register 91 is cleared and the counter 95 is reset, and then the process returns to step 1.

Next, the numeric key 630 is operated to input the permission code. This permission code is preferably set to a certain number of digits in order to prevent input errors. When a permission code is input by operating the numerical key 630, the permission code is stored in the register 91 in the same manner as in steps 1 to 4 described above. At this time, the counter 95 counts the number of digits of the predetermined permission code. Thereafter, the permission code key 632 is pressed. In response to this, after performing the judgment operations in steps 1 to 3 and 7 described above, the permission code key 63 is pressed in step 12.
It is determined that 2 is pressed. Subsequently, in step 13, flags F1 and F3 are reset and flag F2 is set. Subsequently, in step 14, it is determined whether the number of digits in the counter 95 is a predetermined number of digits (for example, four digits) of the permission code. If the number of digits is not the predetermined number, the key input is incorrect and the process returns to step 1. On the other hand, if it is determined that the number of digits is a predetermined number, a flag F3 is set in step 15. In this way, the flag F
3 is set to memorize that a permission code of a predetermined number of digits has been input. This is because the write key 633 is pressed before inputting the permission code, so that an incorrect permission code is stored. This is to prevent input. Subsequently, in step 16, the contents of register 91 are transferred to register 94 and stored. In step 17, the permission code is displayed on the numerical display 66 and the lamp built in the permission code key 632 is lit to indicate that the permission code has been input. At step 18, the permission code stored in register 94 is transferred to storage area 920.
It is determined whether the code corresponds to the permission code used for the lost electronic key unit, which is stored in advance. If the currently input permission code is stored at any address in the storage area 920, it is an error in inputting the permission code, and the step
Proceed to 19. In step 19, the indicator lamp 68
2 is lit and displayed, and the alarm device 85 issues an alarm. This can prevent the permission code written in the electronic key unit that was lost in the past from being input by mistake.

On the other hand, the permission code just entered is stored in the storage area 92.
If it is not stored in any address of 0,
In step 20, it is determined whether the permissible code is a recently used permissible code stored in the permissible code storage area 913. If a permission code different from the recently used permission code is set and input, in step 21 register 9 is entered.
3 is written to the next address of the date storage area 911, and the contents of the register 94 are written to the allowable code storage area 913 at that address. on the other hand,
If the recently used tolerance code matches the currently entered tolerance code, it is determined that the same tolerance code will be used continuously for a certain period of time, and step 22
Proceed to. In step 22, the date information stored in the register 93 is written to the date storage area 912 at the immediately previous address. Then step 23
At , the register 91 is cleared and the counter 95 is reset, and the process returns to step 1. In this way, the permission code to be written into the electronic key unit 70 is set and input.

Next, the operation when writing the permission code set and inputted as described above to the electronic key unit 70 will be explained.

When writing the input permission code to the electronic key unit 70, write it in advance to the electronic key unit 70.
is inserted into the fitting hole 65 to connect the connector 652 and the terminal 73. Thereafter, the write key 633 is pressed. At this time, it is determined in step 1 that there is any key input, and the process proceeds to steps 2, 3, 7, 12, and 24. And step 24
At this point, it is determined that the write key 633 has been pressed, and the process proceeds to step 25. At step 25, the lamp built in the write key 633 is lit up and the permission code stored in the register 94 is displayed on the numerical display 66 as required. Next, in step 26, flag F3 is set.
is set. At this time, if an allowable code of a predetermined number of digits has been input, since the flag F3 was set in step 15, this is determined and the process proceeds to step 27.
At step 27, the authorization code stored in register 94 is output to connector 652 and written into the memory of electronic key unit 70. After that, return to step 1. In this manner, a desired permission code is written into the electronic key unit 70.

Note that the permission code displayed on the numerical display 66 is erased after a certain period of time, if necessary. In this case, the read key 634 is pressed when the user wants to check the permission code later. This read key 6
34, it is determined in step 1 that one of the keys has been input, and steps S2 and 34 are pressed.
The process advances to steps 3, 7, 12, 24, and 28, and it is determined in step 28 that the read key 634 has been pressed. Subsequently, in step 29, the permission code stored in the register 94 is read out and displayed on the numerical display 66, and the lamp built in the read key 634 is lit.

FIG. 11 is a flowchart for explaining the operation when the electronic key unit 70 is used to bring the front frame 32 or the glass frame 33 into a state where it can be opened. Next, referring to FIGS. 1 to 11,
The operation when unlocking the front frame 32 or the glass frame 33 using the electronic key unit 70 will be explained.
The CPU 81 always performs a judgment operation in step 1 to determine whether or not there is any key input.
If there is no key input, the process proceeds to the unlock request processing mode shown in FIG.

By the way, if the staff at the gaming parlor wants to unlock the glass frame 33 of a certain malfunctioning machine, he or she should switch the changeover switch 74 of the electronic key unit 70 to the glass frame side, and then insert the electronic key unit 70 into the connector 27 of the pachinko machine. After connecting, press the push switch 75 to request unlocking.

On the other hand, the CPU 81 determines whether or not there is a high-speed clock pulse φ in normal step 41, and
Waiting for input of clock pulse φ. When the CPU 81 receives the clock pulse φ, it performs the following processing. That is, in step 42, the value 1 is added to the contents of the counter 92. Subsequently, in step 43, it is determined whether the contents of the counter 92 are greater than the maximum value of the machine number. The maximum value of this machine number is ROM83
is set in advance. This judgment is made by
This is to determine whether or not the pachinko machines, which are sequentially designated by machine numbers by the counter 93, have gone through one cycle. If the count value of the counter 92 is smaller than the maximum machine number value, the process advances to step 44. In step 44, it is determined whether or not there is an unlocking request from the pachinko machine having the machine number specified by the contents of the counter 92. This determination is made, for example, based on whether the electronic key unit 70 is connected to the connector 27 and the push switch 75 is pressed. At this time, if the machine number specified by the count value of the machine number counter 92 and the machine number requested to be unlocked do not match, the process returns to step 1. By repeating the above-mentioned operation at high speed, it is determined whether or not there is an unlocking request for each machine, that is, boring processing is performed for each machine.

Note that in step 43 described above, the counter 9
If it is determined that the count value of 2 exceeds the maximum machine number value, the process proceeds to step 45. After the counter 92 is reset in step 45, the process advances to step 44. Then, at the timing when the count value of the counter 92 increments to the machine number of the pachinko machine for which the unlocking request is made, that is, at step 44, the CPU 81 determines from the machine number specified by the counter 92 that there is an unlocking request. , performs the following operations. In step 46, the CPU 81 reads the permission code written in the memory of the electronic key unit 70 via the connector 27 and the interface 82. Subsequently, in step 47, it is determined whether the read permission code matches the permission code stored in the permission code register 94. If they match, in step 48,
Based on the logic state of the most significant bit added to the permission code read from the electronic key unit 70, it is determined whether the unlocking request target is the glass frame 33 (that is, whether the most significant bit is logic "1" or not). to decide. When determining that it is the glass frame 33, in step 49, the CPU 81 gives a glass frame unlocking command signal to the drive circuit 36 included in the pachinko machine corresponding to the machine number specified by the count value of the count 92. The solenoid 44 is energized. As a result, when the electronic key unit 70 matches the permission code of the electronic key unit, the glass frame 33 of the pachinko machine with the machine number to which the electronic key unit 70 is connected to the connector is
is unlocked. On the other hand, if it is determined that it is not the glass frame 33, in step 50 the CPU 81 gives a front frame unlock command signal to the drive circuit 36 included in the pachinko machine with the machine number corresponding to the count value of the machine number counter 93, and solenoid 45 energize.
As a result, the front frame 32 of the corresponding machine number is opened.

Note that instead of electrically unlocking the glass frame or front frame in response to a finger from the management device 60,
If the unlocking mechanism and electrical opening enabling means of the embodiment shown in FIG. 5 are used, only the locking mechanism of the glass frame or front frame is activated, and unlocking using a key is permitted.

By the way, in step 47 described above, if it is desired to determine that the permission code read from the electronic key unit 70 and the permission code stored in the register 94 do not match, step 51 is performed.
Proceed to. In step 51, the permission code read from the electronic key unit 70 is stored in the storage area 920.
Lost electronic key unit 70 stored in
It is determined whether the code is the permissible code written in the . If it is determined that this is the permission code written in the lost electronic key unit 70,
In step 52, the alarm device 85 issues an alarm and the indicator lamp 681 lights up to inform the staff that the lost electronic key unit 70 is being used illegally. Hearing this alarm, the clerk goes to the installation location of the pachinko machine whose machine number is illegally using the electronic key unit 70 and collects the electronic key unit 70. In this way, if an electronic key unit is used illegally, this will be notified without unlocking the glass frame and front frame of the pachinko machine corresponding to that machine number, thereby preventing illegal gaming. There are advantages that can be achieved.

If it is determined in step 51 that the code is not the permission code written in the lost electronic key unit 70, it is determined that the permission code recorded in the electronic key unit 70 has not been updated, and step 51 is performed. Proceed to 53. In step 53, the alarm device 85 issues an alarm to notify that the electronic key unit 70 cannot be used, thereby prohibiting the use of the electronic key unit 70 to enable opening of the glass frame or front frame. do. Thereafter, a usable permission code is written by the management device 60 into the electronic key unit in which an unusable permission code has been written on that day, in the same manner as the above-mentioned permission code writing operation.

Next, referring again to FIG. 10, other operations will be explained. First, an explanation will be given of the operation when printing and recording the permission codes used in a certain period stored in the RAM 900 and the permission codes written in the lost electronic key unit. In this case, after the key switch 62 is switched to the ON position, the print key 635 is pressed.
In response, it is determined in step 30 that the print key has been pressed, and the process proceeds to step 31. In step 31, the CPU 81 sequentially reads out the contents of the RAM 900 and provides them to the printer 84. The printer 84 prints and records the permission codes for each period or date stored in the storage area 910 of the RAM 900, and also prints the permission code written in the lost electronic key unit stored in the storage area 920. Print and record sequentially. An example of the print format printed in this manner is shown in FIG. There is an advantage that by looking at such a printed record, it is possible to easily know the permission code written in the lost electronic key unit.

Next, when an electronic key unit is lost, the operation for setting and inputting the permission code written in the electronic key unit in order to prohibit writing of the permission code and detect unauthorized use will be explained. If you want to enter the permission code written on the lost electronic key unit, first,
Information on the date and time when the electronic key unit was used,
Input is made by pressing the numeric key 630 and date key 631. This is because more people remember the date on which a lost electronic key unit was used than the permission code written on it. In this case, follow steps 1 to 1 above.
In the same manner as in step 11, the information on the year, month, and day that the electronic key unit was lost is entered. After that, when the lost key 636 is pressed, steps S1, 2, 3,
After judgment actions 7, 12, 24, 28, and 30, step 32
Proceed to. In step 32, it is determined that the lost key 636 has been pressed, and the process advances to step 33. In step 33, it is determined whether the flag F1 is set. In this case, if the date information has been input first, it is determined that the flag F1 is set, and the process proceeds to step 34. In step 34, the period corresponding to the date information stored in the register 93 is searched from the period information storage areas 911 and 912, the permission code for the period is read from the permission code storage area 913, and the permission code is stored. Write to a certain address in area 920. As a result, the permission code written in the lost electronic key unit will be transferred to the storage area 9.
The settings are stored in 20. Then, after registers 93 and 94 are cleared in step 35,
Return to step 1.

Note that the input of the permission code written in the lost electronic key unit is not limited to this, and various operation examples can be considered. For example, as mentioned above, if you print out the permission codes used during a certain period of time as shown in Figure 12, and after looking at the contents and inputting the permission code used on the day you lost the electronic key unit, The key 636 may also be operated.

Next, as described above, after printing and recording the information stored in the RAM 900, the RAM 900 is
The operation when clearing the contents of is explained. In this case, turn the key switch 62 to the ON position and press the memory clear key 637. In response, in step 36, the memory clear key 63 is
It is determined that 7 has been pressed, and the process proceeds to step 37. At step 37, various information stored in storage areas 910 and 920 of RAM 900 is cleared.

In the above-mentioned embodiment, the method of setting and inputting the permission code is explained as inputting it by operating the keyboard, but the method is not limited to this, and it is possible to record the permission code in advance on a punch card, perforated tape, etc. , the information may be input by reading it into a card reader. In addition, in a game arcade that stipulates that the permission code is changed every certain period, the permission code for each certain period is magnetically recorded on a magnetic recording medium, and by reading it, the RAM900 The period information and the permission code used for the period are set and stored in the storage area 910 of , and when the date information of the day is input at the beginning of the day, the period information corresponding to that date and the permission code for the period are stored in the storage area 910. Permission codes preset for use may be read and stored in registers 93 and 94.

[Effects of the Invention] As described above, according to the present invention, the door is opened based on the comparison result of the permission code preset and stored in the first storage means and the permission code input from the information storage carrier. In order to make the frame openable, even if the information storage carrier is lost,
Illegal gaming using the lost information storage carrier can be prevented by a simple information change operation such as changing both of the allowable codes, which are the targets of the determination of whether or not to permit development, to something other than the allowable code of the lost information storage carrier. . In addition, when an attempt is made to illegally unlock the door frame using a lost information storage carrier, it becomes possible to notify that fact using the notification means, and the unauthorized use of the lost information storage carrier can be easily discovered. Unique effects such as being able to recover the lost information storage carrier are produced.
