Description

[Detailed Description of the Invention] (a) [Field of Industrial Application] The present invention relates to a lock management device in a gaming hall where pinball gaming machines such as pachinko gaming machines and coin gaming machines are installed. The present invention relates to a locking management device in a game parlor equipped with an electric drive source that enables and disables locking devices for door frames including glass doors and front frames.

[Conventional technology]

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 as to be openable and closable. 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. Further, after the closing point, the glass frame is opened in order to perform nail adjustment. 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 operation command means into the keyhole, and open either one by rotating the key in different rotation directions or rotation angles. I was letting it happen.

[Problem to be solved by the invention]

Incidentally, at game arcades, in order to quickly deal with abnormal situations, such as when a ball gets caught on a nail or a machine malfunctions, the attendants of the game arcade are required to carry a key with them. However, if an employee loses the key and the key is recovered by a player, the player may use the key to illegally open door frames such as the front frame or glass frame to gain advantage. In some cases, illegal games were carried out, such as forcing players to open the Yakumono 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, However, there is a way to prevent people from knowing which machine the key belongs to. 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. Furthermore, if a key necessary for unlocking a certain pinball game machine is to be searched among a large number of keys, there is an inconvenience in that the player feels irritated. For the above reasons, in a game parlor where quick unlocking operations are required, it is not possible to have too many types of keys, and it is necessary to configure a system so that a large number of pinball game machines can be unlocked with one type of key. It is.

On the other hand, if a player who finds a lost key finds out which machine the key is for, there is a risk that the above-mentioned illegal gaming will be carried out, so in order to completely prevent such a risk, Since a plurality of keys corresponding to a lost key must be replaced, this method has the disadvantage of being extremely expensive, troublesome, and complicated work.

Therefore, an object of the present invention is to enable the door frame to be opened at low cost and with simple work, without requiring many lock replacements, even if the key for opening the door frame is lost. The purpose is to prevent illegal games by players as reliably as possible.

[Means to solve the problem]

A locking management device in a game parlor according to the present invention includes: an operation command means in which predetermined operation information is set; and a management device that manages a locked state of the pinball game machine, and the pinball game machine includes: A door frame provided on the pinball game machine so as to be openable and closable; a locking mechanism for locking the door frame; an insertion hole into which a key for operating the locking mechanism can be inserted; and setting the locking mechanism to an operable state and for operation. The management device includes: an electric drive source for disabling the pinball game machine; and an operation information input section provided at a position related to the front surface of the pinball game machine and inputting operation information from the operation command means; permissible information setting means for setting permissible information correlated to the operational information set by the operational command means; and information for comparing the operational information set in the operational command means and the permissible information set by the permissible information setting means. Comparing means; and arithmetic processing means for enabling the locking mechanism to be operated by the electrical drive source when the information comparing means determines that the operating information and the permissible information have a predetermined relationship. It is characterized by the presence of

[Effect]

The operation information set in the operation command means can be input from the operation information input section, and the input operation information is compared with the permissible information on the management device side, which has been set in advance by the permissible information setting means, by the 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 activated.

In addition, even if the operation command means is lost, if the operation information is rewritable, the operation information and permission information can be rewritten, and if the operation information is not rewritable, only the permission information can be rewritten. Unauthorized gaming can be prevented by newly using the operation command means having the operation information.

Moreover, the locking mechanism is unlocked only after a two-stage operation of activating the locking mechanism based on the results of information comparison and unlocking with the key after activation, and the conditions for unlocking the locking mechanism are that much stricter. This can reduce the possibility of the locking mechanism being illegally unlocked.

7 and display devices 28 and 29 are each connected to a management device 60, which will be described later, via connection lines. This management device 60 is installed at the prize exchange place 11, or installed in a management room separate from the gaming hall 10, or installed for each island of pachinko machines or for each pachinko machine. Note that 44 and 45 in FIG. 1 are solenoids, the details of which will be described later.

FIG. 3 is a front view showing a state in which the glass frame of a pachinko machine to which the present invention is applied is opened. As is well known, the pachinko machine 30 includes a game board 31. This game board 31 is integrally attached to the front frame 32. The front frame 32 is attached to an island frame (not shown) or an inner frame of the pachinko machine 30 so as to be openable and closable. A glass frame 33 and a front decorative plate 34 are attached to the front frame 32 so as to be openable and closable. Vertical frame of the front frame 32 (in the illustration, the left vertical frame when viewed from the back of the pachinko machine)
A locking mechanism 40, which will be described in detail in FIGS. 4A to 4C below, is provided inside. The front frame is provided with a keyhole 41 into which a key for operating the locking mechanism can be inserted. The locking mechanism 40 has a key in a keyhole 41.
By being inserted into and rotated, the glass frame 3
3 is unlocked or the front frame 32 is unlocked.

A front glass 331 is attached to the glass frame 33. An engagement piece 332 for engaging with a hook, which will be described later, is formed on the side surface of the open end of the glass frame 33. This glass frame 33 is opened to adjust the nails installed in the game board 31 after the game hall is closed. In addition, the glass frame 33 is used to clear or remove the jammed balls that are installed on the game board 31 when they break down or when balls are stuck between the nails planted on the game board 31 during business hours. It is opened for the purpose of

The front frame 32 is opened so that an operator can repair various mechanisms provided on the back side of the game board 31, such as a prize ball dispensing mechanism or the like when the prize ball dispensing mechanism malfunctions. This front frame 32 and the glass frame 33 constitute a door frame provided in the pachinko machine 30 so as to be openable and closable.

FIGS. 4A and 4B are longitudinal cross-sectional views showing the locking mechanism of the present invention, in which the locking mechanism is activated by energizing a solenoid and unlocked using a key.

Specifically, the keyhole 4 is connected to the front frame 32.
1 is provided. When the locking mechanism 40 inserts the key 51 and rotates, the sliding plate 42 for the glass frame locks.

In connection with the rod 442 fixed to the sliding plate 423, the solenoid 44, which is an example of a first electric drive source,
is provided. When the solenoid 44 is not electrically energized, it projects the plunger and connects the rod 442.
The slide plate 423 is engaged with the slide plate 423 to restrain its downward movement (see FIG. 4A), and the plunger is sucked in response to the electrical bias to permit the slide plate 423 to move downward. (See Figure 4B).

Meanwhile, a solenoid 45, which is an example of a second electric drive source, is provided in association with the hook 431.
When the solenoid 45 is not electrically energized, the solenoid 45 projects its plunger to restrain the upward movement of the hook 431 (see FIG. 4A), and when electrically energized, the solenoid 45 attracts the plunger to prevent the hook 431 from moving upward. The upward movement is allowed, and the engagement piece 432 is unlocked by key operation (see FIG. 4B).
With this configuration, the solenoid 4
Even if 4 or 45 is electrically energized, the glass frame or the front frame is not immediately opened, and the opening is made possible using a key 51. On the other hand, when both solenoids 44 and 45 are not energized, it is impossible to open the glass frame 33 and the front frame 32 even with the key 51, thereby making the locking mechanism inoperable.

As described above, even if it is determined that there is a predetermined relationship between the input unlocking enable information and allowable information, the door frame will not be unlocked immediately, and the door frame will not be unlocked immediately. The locking mechanism of the frame becomes operational and can only be unlocked with a key, and it is necessary to insert the key to actually unlock the frame. In this way, the two-stage operation of determining whether the above information has a predetermined relationship and then unlocking with the key makes it possible to tighten the unlocking conditions and prevent unauthorized opening of the door frame. It is possible to prevent this situation as reliably as possible. In this embodiment, control for opening both the glass frame and the front frame has been described, but it is also possible to open only the glass frame or only the front frame. That is, the door frame in the present invention may include both the glass frame and the front frame, or may mean only either the glass frame or the front frame. In addition, the electric drive source may be a motor in addition to a solenoid, or any type of electric drive source that generates a drive force by electrically operating an air cylinder or the like controlled by a conventionally well-known electromagnetic valve. However, the present invention can be practiced.

FIG. 5 is an external view of the management device 60, which is a feature of the present invention. In the figure, the management device 60 includes an operation panel 611 and a display panel 612 formed on the front side of a housing 61. A key cylinder switch (hereinafter referred to as a key switch) 62 is provided on the operation panel 611. The key switch 62 is

The all-glass frame key 632 is used to remotely command the first electric drive source of the first locking mechanism for all the glass frames installed in the game parlor. The glass frame single key 633 is used to issue a drive command to the first electrical drive source of the first locking mechanism for the glass frame 33 corresponding to the unit number input by operating the numerical key 630.

Note that the numerical key 630 also serves as a machine number setting input means for setting and inputting a machine number. The front frame all-unit key 634 is used to issue a drive command to the second electrical drive source of the second locking mechanism for the front frame 32 of all units. This front frame all unit key 6
34 and the glass frame all-machine key 632 constitute an all-machine operation command signal output means for outputting an operation command means to an electric drive source for enabling the locking mechanisms of all pinball game machines. .

The front frame single key 635 is used to issue a command to open the front frame corresponding to the machine number input by operating the numerical keys 630. The glass frame single key 633 and the front frame single key 635 are used to command an operation signal to output an operation signal to an electric drive source that enables the locking mechanism of the pinball game machine set by the machine number setting input means. A signal output means is configured. The read key 636 is used to instruct reading of the permission code after writing the permission code. Furthermore, display lamps 641 to 646 are provided on the operation panel 611 at positions corresponding to the keys 631 to 636 to display the operation status of each key.

Furthermore, a plurality of fitting holes 65 are formed in the operation panel 611. Inside this fitting hole 65,

is the outer periphery of the fitting protrusion 72, and the electronic key unit 70 is connected to the connecting member 27 or the fitting hole 6.
It is formed in the direction of insertion into 5. The memory built into the electronic key unit 70 is preferably P-
Non-volatile memory such as ROM is used. Further, as another example of the memory, when a volatile memory such as a RAM is used, a battery may be built in and the circuit may be configured to prevent the storage contents of the RAM from being destroyed by the battery.

More preferably, a changeover switch 74, which is an example of a selection means, is provided to switch between opening the front frame 32 and opening the glass frame 33. And input/output terminal 73
The number of terminals is increased by one bit in addition to the number of bits of the permission code, which is an example of operation information consisting of multi-digit numerical information stored in the memory. This added 1 bit is the changeover switch 7.
This bit is used as a command to switch the front frame or the glass frame based on the switching of 4. For example, when the most significant bit of the bit parallel data derived from the input/output terminal 73 is logic "0", the front frame 32 is selected, and when the logic is "1", the glass frame 3 is selected.
3 shall be selected. Further, a push switch 75 is provided in a part of the housing 71. This push switch 75 is used to request data readout when the housing 71 is attached to the first connecting member 27 provided at the top of the pachinko machine.

Although the electronic key unit 70 of this embodiment has been described as having rewritable operation information, it is possible to not rewrite the operation information of the electronic key unit 70, but to rewrite only the permission information on the management device side, and to have a corresponding permission code. The object of the present invention can also be achieved by newly using the electronic key unit 70.

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.

The responsible person code register 95 stores a code specific to the responsible person, which is determined so as to be able to change the allowable code, for example, and transfers and stores the responsible person code, which is preset and stored in the ROM 83, when the power is turned on. do. This responsible person code is
Since it has a more important meaning than the permission code and requires stricter judgment, it is chosen to have a larger number of digits (for example, 7 digits) than the permission code (4 digits).
The machine number maximum value register 96 stores the maximum value of the machine numbers installed in the gaming hall. The maximum value of this machine number is usually constant at a single amusement park, so
The settings are stored in the ROM 83 in advance and transferred to and stored in the register 96 when the power is turned on.

Incidentally, if it is necessary to change the manager code and the maximum machine number, the manager may always set them at the time of opening the gaming hall without storing the settings in the ROM 83 in advance.

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.

The CPU 81 constantly performs an operation to determine whether any key input is made. If the number keys 630 are operated, it is determined that any key has been input. Next, key switch 62
is 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, the numerical key 630
Each time numeric key 630 is operated, the numeric value input by operating numeric key 630 is stored in 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 . In other words, the CPU 81 inputs any key, the key switch 62 is not in the LOCK position, the numeric key 630 is not in the LOCK position, and the key switch 62 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. The permission code stored in the permission code register 94 is written to the memory of the electronic key unit 70 connected to the plurality of connectors 652. Subsequently, the permission code stored in the permission code register 94 is displayed on the numerical display 661. 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 frames key 632 is pressed, the flag F2 is set. In response, the display lamp 642 is lit. Subsequently, it is determined whether the responsible person code stored in advance in the register 95 and the contents of the numerical register 91 match. If they match, the CPU 81 provides a signal via the interface 82 to the drive circuits 36 of all pachinko machines 30 to energize the solenoids 44. Accordingly, the drive circuit 36 of each pachinko machine
energizes and controls the solenoid 44. As a result, the first locking mechanisms for the glass frames 33 of all pachinko machines become operable.

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.

In other words, the arithmetic processing means performs all-machine operation control that causes the locking mechanism of each pinball game machine in all machines to be activated by the electric drive source in response to the operation of the all-machine operation command signal output means. Contains means.

Note that when the locking mechanism of the glass frame 33 or the front frame 32 is to be enabled for all units, it is not necessary to enable all units at once, but to enable each unit one by one. It can also be unlocked with a key.

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.

Next, the CPU 81 controls the drive circuit 3 of the pachinko machine with the machine number corresponding to the machine number stored in the machine number register 92 via the interface 82.
A signal for instructing the second electric drive source of the second locking mechanism for the front frame to be applied to the control unit 6. Accordingly, the drive circuit 36 of the vehicle number energizes the solenoid 45, thereby enabling the second locking mechanism for 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 similar to the operation when the second locking mechanism for the front frame of the desired machine number becomes operational, 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. The locking mechanism includes a vehicle number corresponding type operation control means for enabling the locking mechanism to be operated by the electric drive source.

In this way, according to this embodiment, there is an advantage that the locking mechanism of a desired machine number or the front frame or glass frame of all the machines among a plurality of pachinko machines can be controlled to be in an operable state. There is.

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 the lock is placed in an unlockable state. 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 judgment step constitutes an information comparison means that compares the operation information set in the operation 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) is determined. glass frame 33
When determining that this is the case, the CPU 81 applies a glass frame activation 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 energizes the solenoid 44.
As a result, when the electronic key unit 70 is matched with the permission code of the electronic key unit, the glass frame 33 of the pachinko machine having the machine number to which the electronic key unit 70 is connected to the connector can be unlocked using a lock.

On the other hand, when determining that it is not the glass frame 33,
The CPU 81 is a drive circuit 36 included in the pachinko machine with the machine number corresponding to the count value of the machine number counter 93.
The front frame unlock command signal is given to the solenoid 45.
energize. As a result, the front frame 32 of the corresponding machine number can be unlocked using the key. That is, the arithmetic processing means includes selection operation control means for enabling the first or second locking mechanism by the first or second electric drive source according to the selection state of the selection means. include.

〔Effect of the invention〕

The present invention having the above configuration sets the door frame in an unlockable state based on a comparison result of two types of information: permission information preset in the management device and operation information issued from the operation command means. By doing so, the same effect as using multiple types of keys can be obtained. In addition, even if the operation command means is lost, it is possible to perform a simple information change operation by changing the permission information and operation information that are used to determine whether or not to operate to something other than the operation information of the lost operation command means. This also has the effect of preventing illegal games using lost operation command means. Furthermore, 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 key management becomes easier.

Moreover, by tightening the unlocking conditions through the two-stage operation, it is possible to reduce the chances of the locking mechanism being unlocked illegally, and from this point of view as well, it is possible to further reliably prevent illegal games.
