Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a lock management system in a game hall, and in particular, door frames including glass frames and front frames are locked using mechanical locks and keys. Instead of
The present invention relates to a locking management system in a game parlor that is electrically operated based on electrical type.

[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, a front frame and a glass frame are respectively attached to the front surface of the game machine 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 that can be opened and closed and integrally supports the game board, and can be opened and closed to repair various mechanisms installed on the back of the game board when they break down. It is attached to the island frame to which the pinball game machine is attached.

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, insert a common key as an unlocking command means into the keyhole, and rotate the key in different directions or angles to open either one. It was developed.

[Problems to be Solved by the Invention] Incidentally, in amusement arcades, in order to quickly deal with abnormal situations, such as when a ball gets caught on a nail or a machine malfunctions, the employees of the amusement arcade are given the keys. I have it carried. However, if an employee loses the key and the key is recovered by a player, the player can use the key to illegally open the front frame or glass frame and force the player to use the key to his advantage. There have been cases where players have engaged in illegal games such as opening the gates or adjusting the nails.

Therefore, in order to prevent such illegal games, among all the pinball game machines in the amusement park, different types of keys are assigned to each pinball game machine on an island basis, so that even if the key is lost, Even in cases where the key was locked, the user did not know which machine the key belonged to. As a result, the number of types of keys to be managed at one gaming parlor increases, resulting in problems such as insufficient key management.

In addition, if a player who found a lost key were to find out which machine the key belonged to, there was a risk of illegal gaming. In order to completely prevent this risk, the lock corresponding to the lost key must be replaced. However, exchanging keys requires exchanging many units at once, which is extremely expensive and troublesome.

Therefore, an object of the present invention is to unlock the locking mechanism based on the comparison result between the unlocking information set in the unlocking command means and the permissible information set in the management device. It is possible to obtain an effect equivalent to increasing the number of types of keys, and furthermore, it is possible to prevent illegal games even if the unlocking command means is lost.

[Means for Solving the Problems] A locking management system in a gaming hall according to the present invention includes: an unlocking command means in which predetermined unlocking information is set; and managing the locked state of the pinball gaming machine. The pinball game machine includes: a door frame provided on the pinball game machine so as to be freely openable and closable; a locking mechanism that locks the door frame; and an electric drive source that operates the locking mechanism. , an unlocking information input unit provided at a position related to the front surface of the pinball game machine and inputting unlocking information from the unlocking commanding means, and the management device is configured to: permissible information setting means for setting permissible information correlated to the unlocking information set by the user; and information comparing means for comparing the unlocking information set in the unlocking command means with the permissible information set by the permissible information setting means. , when the information comparing means determines that the unlocking information and the permission information are in a predetermined relationship, the information comparing means is configured to include arithmetic processing means for unlocking the locking mechanism by the electric drive source. It is characterized by

[Operation] The unlocking information set in the unlocking command means can be input from the unlocking information input section, and the input unlocking information and the permission information on the management device side set in advance by the permission information setting means can be combined. are compared using information comparison means,
If the information comparison means determines that the unlocking information and the permission information have a predetermined relationship,
The locking mechanism of the door frame is unlocked.

In addition, even if the unlocking command means is lost, if the unlocking information is rewritable, the unlocking information and permission information are rewritten, and if the unlocking information is not rewritable, only the permission information is written. Unauthorized gaming can be prevented by rewriting and using a new unlock command means having corresponding unlock information.

The object of the present invention can also be achieved by newly using the electronic key unit 70 having the following.

FIG. 7 is a block diagram of a lock management device according to an embodiment of the present invention. In the configuration, the plurality of pachinko machines 30 include a connector 27 included in the first connection member, a drive circuit 36 that drives and controls the solenoids 44 and 45, and the indicators 28 and 29. These connectors 27, drive circuit 36, and displays 28 and 29 are connected to an interface 82 included in management device 60. Note that the drive circuit 36 may be provided on the management device 60 side.

The management device 60 is a CPU, which is an example of arithmetic processing means.
Contains 81. The CPU 81 includes the keyboard 6
3, a numerical display 66, a door frame open state display 67, and a second connection member (for example, a connector) 6
52 is connected. Further, an interface 82 is connected to the CPU 81, and a ROM 83 and a RAM 90 are connected in which programs shown in FIGS. 9 and 10, which will be described later, are stored in advance. Note that a printer 84 is connected to the CPU 81 as necessary.

FIG. 8 is a diagram schematically showing a memory map of the RAM 90. RAM 90 includes a plurality of register areas 91 to 96 and a flag area F. The numerical register 91 stores numerical information input by operating the numerical keys 630. The machine number register 92 stores the machine number of a pachinko machine whose glass frame or front frame is to be opened remotely. The machine number counter 93 is used to designate a machine number for sequentially determining whether there is an unlocking request from each pachinko machine. Permissible code register 94
is used to store the same code as the permission code written in the memory included in the electronic key unit 70 that is permitted to open the glass frame or front frame. Responsible person code register 95
stores a code unique to the person in charge determined to be able to change the permission code, for example, and transfers and stores the person-in-charge code, which is preset and stored in the ROM 83, when the power is turned on.

This supervisor code has a more important meaning than the tolerance code and requires strict judgment, so it has a larger number of digits (for example, 7 digits) than the tolerance code (4 digits).
(number of digits) is selected. Machine number maximum value register 9
6 stores the maximum value of machine numbers installed in the game hall. Since the maximum value of this machine number is usually constant in one game parlor, it is set and stored in the ROM 83 in advance, and is transferred and stored in the register 96 when the power is turned on. In addition, if it is necessary to change the supervisor code and maximum machine number, please change them in ROM83.
Instead of storing the settings in advance, the person in charge may always set the settings when the game parlor opens.

FIG. 9 is a flowchart illustrating operations for processing based on operations on the keyboard 63 of the management device 60.

Next, the operation for setting and inputting the permission code will be described with reference to FIGS. 5 to 9.

When setting and inputting a permission code and controlling the electronic key unit 70 by writing the desired permission code,
After switching the key switch 62 to the ON position, the following operations are performed. That is, after first operating the numerical keys 630 to input numerical information representing a desired permission code, the write key 631 is pressed. Now, assume that a desired permission code is input by operating the numeric key 630. CPU81
is constantly determining whether any key input has been made. If the numeric key 630 is operated, it is determined that any key has been input.

Next, it is determined 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 by operating the keyboard 63 is prohibited, and in that case, the following operations will not be performed. In this case, since the key switch 62 is set to the ON position, it is determined that the key operated first is the numeric key 630. Subsequently, the contents of the numerical value register are shifted by one digit, and the numerical information just inputted is written into the least significant digit. Subsequently, each flag included in flag area F is reset.
Thereafter, the process returns to the key input waiting step described above. In this way, each time the numeric key 630 is operated, the numeric value input by operating the numeric key 630 is stored in the numeric register 91. Note that the contents of the numerical register 91 are displayed on the numerical display 661 as necessary.

After that, when the write key 631 is pressed,
The CPU 81 uses the numerical register 91 as shown below.
Writes the numerical information (ie, the permission code) stored in the . That is, the CPU 81 receives any key input, and the key switch 62 is not in the LOCK position, the numeric key 630 is not in the LOCK position,
It is determined that it is the write key 631. and,
Logic "1" is written to flag F1. In response, the display lamp 641 is lit to indicate that the code is being written. Subsequently, the contents of the numerical value register 91 are transferred to the permissible code register 94 and stored therein. Permissible code register 94
Allowable codes stored in multiple connectors 65
2 is written into the memory of the electronic key unit 70 connected to the key unit 2. Next, allowable code register 9
The allowable code stored in 4 is displayed on numeric display 6.
61. This display may continue to be displayed during other operations, or may disappear after a certain period of time. Thereafter, after all the flags in flag area F have been reset, the process returns to the key input waiting step.

Note that when the display of the permission code is erased, if the user wishes to check it later, this is done by pressing the read key 636. That is, read key 636
When it is determined that the button is pressed, flag F6 is set. In response, the display lamp 646 is lit up. Thereafter, the contents stored in the allowable code register 94 are displayed on the numerical display 661.

Next, a case will be described in which the management device of the present invention is used to remotely open the front frame 32 or glass frame 33 of all pachinko machines or a specified machine number. For example, the glass frame 33 of all units
To open the system, the person in charge operates the numerical keys 630 to input the person in charge code, and then presses the glass frame all units key 632. That is, the person in charge code input by operating the numeric keys 630 is stored in the numeric register 91 in the same manner as in the case of inputting the numeric keys described above. Thereafter, when the all glass frame key 632 is pressed, the flag F2 is set. In response, the display lamp 642 is lit. Next, register 9
It is determined whether or not the responsible person code stored in advance in 5 matches the contents of the numerical register 91. If they match, the CPU 81 sends information to all pachinko machines 30 via the interface 82.
A signal for energizing the solenoid 44 is given to the drive circuit 36 of the solenoid 44 . In response, the drive circuit 36 of each pachinko machine energizes the solenoid 44. As a result, the glass frames 33 of all pachinko machines are unlocked.

In addition, when opening the front frame 32 of all machines, this is done by operating the numeric keys 630 to input the responsible person code, and then pressing the front frame all machines key 634. Since the operation in this case is the same as the opening operation of all the glass frames 33, only a flowchart will be shown and the explanation thereof will be omitted.

That is, the arithmetic processing means is an all-machine unlocking control means for unlocking the locking mechanism of each pinball game machine in all machines by the electric drive source in response to the operation of the all-machine unlocking command operating means. Contains.

In addition, when opening all the glass frames 33 or front frames 32, instead of opening all the frames at once, the locking mechanism may be unlocked one by one to open the glass frames one by one.

Next, the operation for opening the front frame of a pachinko machine with a desired machine number will be explained. A staff member (not limited to the person in charge) of the game parlor operates the numerical keys 630 to input the machine number. In response, the numerical information of the designated machine number is stored in the numerical register 91 in the same manner as the above-described operation. Thereafter, the staff member presses the front frame single key 635. In response, it is determined that the front frame single key 635 has been pressed. Subsequently, the flag F5 is set and the display lamp 64
5 is lit. Subsequently, the machine number stored in the numerical register 91 is transferred to and stored in the machine number register 92, and the numerical value display 662
will be displayed. Subsequently, the CPU 81 provides a signal through the interface 82 to the drive circuit 36 of the pachinko machine whose machine number corresponds to the machine number stored in the machine number register 92, instructing it to open the front frame. In response, the drive circuit 36 of the vehicle number energizes the solenoid 45 to open the front frame.

When opening a glass frame with a desired unit number, the operator operates the numerical keys 630 to input the unit number, and then presses the glass frame single key 633. The operation in this case is the same as the operation when opening the front frame of the desired machine number, so only a flowchart is shown and the explanation thereof will be omitted. That is, in response to the machine number being input by operating the machine number setting input means and the unlocking command operation means being operated, the arithmetic processing means controls the pinball game machine corresponding to the machine number. It includes an unlocking control means corresponding to the machine number for unlocking the locking mechanism using the electric drive source.

In this way, this embodiment has the advantage of being able to remotely control the opening and opening of a desired number of pachinko machines or the front frames or glass frames of all the machines among the plurality of pachinko machines.

FIG. 10 shows a front frame 32 or a glass frame 33 using an electronic key unit 70, which is a feature of the present invention.
This is a flowchart for explaining the operation when unlocking. Next, the characteristic operation of the present invention will be explained with reference to FIGS. 1 to 10.
The CPU 81 constantly determines whether there is any key input, but 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 normal high-speed clock pulse φ, and waits for the input of the clock pulse φ. And CPU8
1 performs the following processing when the clock pulse φ is input. That is, the value 1 is added to the contents of the machine number counter 93. Subsequently, it is determined whether the contents of the machine number counter 93 are larger than the contents of the maximum machine number register 96. If the count value of the machine number counter 93 is smaller than the maximum machine number value, then it is determined whether or not there is an unlocking request from the pachinko machine with the machine number specified by the contents of the machine number counter 93. . 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 93 does not match the machine number requested for unlocking, the process returns to the step of determining whether or not there is a key input. Then, 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, polling processing is performed for each machine. Then, at the timing when the count value of the machine number counter 93 increments to the machine number for which unlocking is requested,
The CPU 81 determines that there is an unlock request from the machine number specified by the counter 93, and performs the following operations. That is, 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, it is determined whether the read permission code matches the permission code stored in the permission code register 94. This determination step constitutes information comparing means for comparing the unlocking information set in the unlocking command means and the permissible information set by the permissible information setting means. If they do not match, an error message is displayed, the machine number is displayed, and an alarm is issued to alert the staff. On the other hand, if they match, it is determined based on the logical state of the most significant bit added to the permission code read from the electronic key unit 70 whether or not the unlocking request target is the glass frame 33 (that is, whether the most significant bit is whether the logic is “1” or not).

When determining that the glass frame is 33, 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 counter 93, and the solenoid 44
energize. 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 unlocked. On the other hand, when determining that the frame is not the glass frame 33, 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 energizes the solenoid 45. let As a result, the front frame 32 of the corresponding machine number is opened. That is, the arithmetic processing means includes selective unlocking control means for unlocking the first or second locking mechanism by the first or second electric drive source according to the selection state of the selection means. ing.

[Effects of the Invention] The present invention having the above-mentioned configuration is capable of controlling the door frame based on the comparison result of two types of information: the permission information preset in the management device and the unlocking information issued from the unlocking command means. By unlocking the lock, the same effect as using multiple types of keys can be obtained. Also,
Even if you lose the unlocking command means, you can easily change the information by changing the permission information and unlocking information that are used to determine whether or not to allow unlocking to something other than the unlocking information of the lost unlocking command means. This operation also has the effect of preventing fraudulent games using the lost unlock command means. Further, it is possible to eliminate the need for mechanical keys for pinball game machines throughout the gaming hall, and there is also the effect that mechanical keys can be easily managed.
