Description

Description: TECHNICAL FIELD The present invention relates to an unlocking control device for a gaming machine that limits an unlockable time of the gaming machine to operate an unlocking mechanism section.

[Prior Art] Conventionally, unlocking of a gaming machine is made up of a mechanical key and a lock. Here, a pachinko machine is a typical example of a game machine that is frequently unlocked. A large number of pachinko machines are arranged in the store, and usually, a single key can unlock all the locks (or a plurality of locks divided into several groups). Further, it is considered that the key is electrically connected or a magnetic body is installed on the key and a switching operation is performed by the magnetic force of the magnetic body to supply a predetermined voltage to unlock the lock. As a result, the clerk can immediately deal with a mechanical trouble pointed out by the player (generally, lighting of a lamp installed on each pachinko machine).

However, in such a mechanical key and lock configuration,
It is easy to unlock the key illegally by picking it up or copying it, which causes inconvenience in security measures for key management. In order to solve this problem, there has been proposed a key management system in which a key is made into a card, a magnetic, optical or electric code is added, the code is discriminated and unlocked. According to this, it is possible to prevent the key from being duplicated, and when the key is lost, register the lost code so that it cannot be unlocked, so that the key cannot be unlocked even if it is caught and used illegally. You can

[Problems to be Solved by the Invention] However, the key management system as described above has a complicated structure, and in order to collectively manage a large number of gaming machines, the number of parts becomes large and the control becomes complicated, resulting in cost up. Connect

In consideration of the above facts, the present invention provides an unlocking control device for a gaming machine, which can prevent unauthorized unlocking with a simple structure such as a mechanical key and lock structure and can safely manage the gaming machine. Is the purpose.

[Means for Solving Problems] An unlocking control device for a gaming machine according to the present invention includes an unlocking mechanism section for unlocking the gaming machine, and a locking means for blocking the operation of the unlocking mechanism section. When the operation switch operated when unlocking the game machine attached to the game machine is required, and when the operation switch is turned off again after the duration of the on state of the operation switch exceeds a predetermined time T _1. And lock releasing means for releasing the blocking state by the locking means for a certain period of time T ₂ to enable the unlocking mechanism section to operate.

[Operation] The unlocking mechanism unit prevents unauthorized unlocking by normally preventing the unlocking operation of the unlocking mechanism unit even if the key is operated by the locking means. Here, when unlocking the gaming machine is required, for example, when a failure occurs, the player operates the operation switch to notify the staff. The clerk who senses this notification unlocks the gaming machine, but normally the locking means is operating and the unlocking mechanism is not operated.

In the present invention, after the operation switch is turned on, the on state is maintained for a predetermined time T ₁ and then the operation switch is turned off and then the lock release means causes the lock release means to perform a predetermined time T _2. Is released to enable the unlocking operation of the unlocking mechanism section by the key. This predetermined time T ₁ corresponds to a time that the staff can sufficiently detect, so that the unlocking mechanism section must be operated unless the person who picks up the key and tries to illegally use the key turns on the operation switch once. Even if the operator knows that the lock is locked, the clerk can sufficiently detect the ON state of the operation switch, so that the unauthorized use can be prevented.

Since after the operation Suitsuchiofu then releases the unlocking blocking state at a predetermined time T ₂ by lock release means (after a predetermined time T ₂₎ activates the lock means again, safety management is maintained.

In this way, it is possible to improve safety management while applying the mechanically configured key and lock that have been conventionally used, and since the structure is simple and the number of parts is small, for example, a large number of pachinko machines, etc. Even if the gaming machines are collectively managed, the management becomes easy and the cost is low.

[First Embodiment] FIG. 1 shows a pachinko machine 10 to which an unlocking control device according to the present invention is applied.

A plurality of pachinko machines (10) are arranged in parallel, and are supported by upper and lower support bars (12, 14) and each is partitioned by a partition member (16). Pachinko machine 10 and partition 16
Are connected at both ends in the vertical direction via hinges 18, and the pachinko machine 10 has a rotating shaft of the hinges 18 (partitioning member 16
(Parallel to the longitudinal direction of) is rotatable about the front side of the drawing. Further, the glass frame 22 supporting the glass plate 20 installed on the front surface of the pachinko machine 10 has a double frame structure, and the inner frame 22A can be opened to the outer frame 22B by the hinge 24. . This pachinko machine 10 and inner frame 22A
Are frequently opened and closed in order to eliminate clogging of pachinko balls, but they are locked so that no one other than the staff can easily open them, and the unlocking of each pachinko machine 10 is performed. The lock 26 attached near the center of the right side of FIG. 1 is made by a key (not shown). When the key is inserted into the key hole 38 of the lock 26 and rotated counterclockwise, the lock of the pachinko machine base 10 is released, When the key is rotated clockwise, the inner frame 22A is unlocked. That is, as shown in FIG. 2, the lock 26 is provided with two unlocking portions 35 and 36, which are operated by the rotation of the key cylinder 32, at the leading end portion in the key insertion direction, and the lock 26 is inserted into the key hole 38 of the key. By inserting and rotating each in the clockwise direction or the counterclockwise direction, the mutual unlocking is possible. In the vicinity of the cylinder 32, a solenoid, which is a locking means, corresponds to a part of its peripheral surface.
40 is disposed, and the plunger 42 thereof is normally inserted into a circular hole 37 provided in the cylinder 32 to prevent the insertion of the key. Here, when the solenoid 40 is energized, the plunger 42 is removed from the circular hole 37 so that the key can be inserted.
The solenoid 40 is energized by a drive circuit 60 described later.

By the way, an operation switch 28 for calling a clerk is installed above each pachinko machine 10 and is used as a means for the player to notify the clerk when a ball is clogged as described above. That is, when the pachinko machine 10 is unlocked, the operation switch 28 is always operated. When the operation switch 28 is turned on, the lamp 30 installed adjacent to the operation switch 28 lights up,
A notification lamp (not shown) attached at a predetermined position in the store is turned on. This notification lamp is provided for each row of the pachinko machine 10 in which a plurality of rows are arranged.
First, check the row of the pachinko machine 10 on which the operation switch 28 has been operated by this notification lamp, and then check each pachinko machine 10
Check the lamp 30 and search for it. In this embodiment, the operation of the operation switch 28 which is inevitable is used to limit the time when the pachinko machine 10 can be unlocked.

As shown in FIG. 3, the first contact 44 of the operating switch 28.
(ON side of the lamp) is connected to the power supply line 48 and the quick charging line 48A via the resistor 46. Also, common terminal 50
Is grounded via a capacitor 52. The second contact 54 (off side of the lamp) of the operation switch 28 is connected to the first level judgment circuit 56 which constitutes a part of the lock releasing means,
The middle part is grounded via a resistor 58. As a result, when the operation switch 28 is off, the capacitor 52 is discharged via the resistor 58.

The first level determination circuit 56 determines whether the input voltage is equal to or higher than a predetermined reference level, and outputs a drive signal to the drive circuit 60 when the input voltage is equal to or higher than the predetermined level. The drive circuit 60 energizes the solenoid 40 (see FIG. 2) installed in the lock 26 on the basis of the drive signal to remove the plunger 42 of the solenoid 40 from the movement locus of the movable portion (hook 34) of the lock 26. It has become. As a result, the lock 26 can be unlocked by operating the key.

Also, the common terminal 50 of the capacitor 52 and the operation switch 28 is
From between and, the signal is branched to the level determination circuit 62, and is further connected to the first contact 44 (on side) of the switch 28 through the quick charging circuit 64. As a result, after the operation switch 28 is turned on and the capacitor 52 is started to be charged, the second level determination circuit 62 determines whether or not this charge is equal to or higher than a predetermined level (the position indicated by the chain line in FIG. 4). become. Here, when the charging of the capacitor 52 reaches a predetermined level, the quick charging circuit 62 operates to accelerate the charging speed of the capacitor 52 and immediately set the power supply voltage level (see the dashed line in FIG. 4). . Therefore, when the operation switch 28 is switched from the off state to the on state, and this on state is continued for a sufficient time T ₁ for the capacitor 52 to be charged to the power supply voltage, the next off state causes the capacitor 52 to switch to the first state. The time T ₂ for making an affirmative decision (above a predetermined level) by the level decision circuit 56 can be made sufficiently and constant. The time T ₂ is the time for energizing the solenoid 40, and the unlocking work can be performed only within this time.

Here, in this embodiment, the resistor 46 and the capacitor 52 are set to relatively large values, the resistance value of the resistor 58 is set to a relatively small value, and the predetermined level (the position of the chain line in FIG. 4) is charged to the capacitor. The voltage is set relatively lower than the voltage (the position indicated by the dashed line in FIG. 4). Thus, so that the capacitor the time to be charged (T ₁₎ and to ensure the predetermined level (Figure 4 position of the chain line) of decrease time (T ₂₎ for a predetermined time from the charging voltage.

The operation of the first embodiment will be described below with reference to the time chart of FIG.

When the operation switch 28 is turned off and a sufficient time has passed, the capacitor 52 is discharged through the resistor 58 and its potential is zero. Here, when the operation switch 28 is turned on, the charging of the capacitor 52 is started, but when the operation switch 28 is turned off again within the time T ₁ , the charged amount of the capacitor 52 is at the first level. The predetermined level for operating the determination circuit 56 is not reached, and the drive signal is not output from the first level determination circuit 56.

Next, when the operation switch 28 is turned on again, the capacitor 52 starts charging again. Here, the operation switch 28
If the ON state of is continued, the second level determination circuit 62 determines that the level is equal to or higher than a predetermined level (the position indicated by the chain line in FIG. 4), and the quick charging circuit 64 operates. As a result, the power supply voltage is applied to the capacitor 52 through the quick charging circuit 62 and the contacts 44 and 50 of the switch 28 to rapidly charge the capacitor 52, and after the time T ₁ , it is charged to the position indicated by the alternate long and short dash line in FIG.

When the operation switch 28 is changed from the on state to the off state from this state, the capacitor 52 is connected to the common terminal 50 and the second contact 54.
To start discharging. At this time, a drive signal is output to the drive circuit 60 for a predetermined time T ₂ (while the potential of the capacitor 52 is a predetermined level or higher), the solenoid 40 is energized, and the plunger 42 is removed from the key hole 38. Let As a result, the lock 26 can be unlocked by operating the key.

When the predetermined time T ₂ has elapsed, the first level determination circuit 56 determines that the charge amount of the capacitor 52 is less than the predetermined value, and the output of the drive signal to the drive circuit 60 is stopped. As a result, the plunger 42 of the solenoid 40 is again inserted into the keyhole 38,
You will not be able to insert the key. As a result, it is possible to prevent the unlocking of the lock 26.

In this way, the operation switch 28 cannot be unlocked unless it is turned on for a predetermined time T ₁ , so even if an unauthorized person knows this, the clerk can use the lamp 30 before unlocking. It can be confirmed that the operation switch 28 is in the ON state, and the safety management aspect is improved.

[Second Embodiment] A second embodiment of the present invention will be described below. In addition,
In the second embodiment as well, the pachinko machine 10 will be described as an example of the game machine, but the structure of the lock and the locking means is the same as that of the first embodiment, so that the description thereof will be omitted and only the lock unlocking means will be described. explain. Further, the same parts are designated by the same reference numerals, and the description of the configuration will be omitted.

As shown in FIG. 5, the power supply line 66 is connected through the resistor 68 to the first contact 44 of the operation switch 28 (on side of the operation switch 28).
It is connected to the. The second contact 54 of the operation switch 28 (off side of the operation switch 28) is grounded via the resistor 70. The common terminal 50 of the operation switch 28 is connected to the third level judgment circuit 71 and is grounded via the first capacitor 74. The third level determination circuit 71 is
For example, the zener diode 73 and the first transistor 72 are main components, and the common terminal 50 is connected to the base of the first transistor 72 via the zener diode 73.

The collector of the first transistor 72 is connected to the power supply line 66 via the resistor 76 forming a part of the third level judgment circuit, and the emitter is grounded. One end of a resistor 78 is connected between the collector of the first transistor 72 and the resistor 76, and the other end of the resistor 78 is connected to the fourth level determination circuit 79. Resistor 78 and fourth level judgment circuit
It is grounded to 79 via the second capacitor 82. The fourth level judgment circuit 79 is mainly composed of, for example, a Zener diode 81 and a second transistor 80, and the other end of the resistor 78 is connected to the base of the second transistor 80 via the Zener diode 81. It is connected.
The collector of the second transistor 80 is connected to the power supply line 66 via the resistor 84 forming a part of the fourth level judgment circuit 79, and the emitter is grounded.

The collector of the first transistor 72 and the collector of the second transistor 80 are connected to the input sides B and A of the AND circuit 86, respectively. The AND circuit 86 outputs a drive signal (high level signal) to the drive circuit 60 when both the first transistor 72 and the second transistor 80 have a high level “1”. In the drive circuit 60, the solenoid 40 is energized according to this signal, and the plunger 42
Is removed from the lock hole 38 (see FIG. 2).

The operation of the second embodiment will be described below with reference to the time chart of FIG.

When the operation switch 28 is in the off state (on the contact 54 side) and a sufficient time has passed, the first capacitor 74 is discharged and the first transistor 72 is also in the off state. As a result, a high level "1" signal is supplied to the input B of the AND circuit 86. On the other hand, since the second transistor 80 is supplied with power via the resistor 76 and the resistor 78, it is in the ON state, and the second capacitor 82 is charged. As a result, a low level “0” signal is supplied to the input B of the AND circuit 86,
Output becomes low level.

Here, when the operation switch 28 is turned on for a time shorter than the predetermined time T ₁ and then turned off again, the charge amount of the first capacitor 74 does not reach the predetermined level, so that the output changes to another output. , And the above condition is maintained.

Next, when the operation switch 28 is turned on, and this is continued (continuation of the predetermined time T ₁ ), the first capacitor 74 reaches the predetermined level and the first transistor 72 is turned on, which causes the AND circuit 86 to operate. Input B goes low. When the first transistor 72 is turned on, the second capacitor 82 is discharged through the resistor 78 and the second transistor 80 is turned off at the same time when the discharge starts. As a result, the input A of the AND circuit 86 becomes high level, and as a result, both inputs A and B are inverted, and the output of the AND circuit 86 remains low level.

Here, when the operation switch 28 is turned off again, the charged first capacitor 74 starts discharging. When the charge amount falls below a predetermined level, the first transistor 72
Is turned off again, and the input B of the AND circuit 86 becomes high level.

On the other hand, when the first transistor 72 is turned off, the charging of the second capacitor 82 is started, but this charging time requires a predetermined time T ₂ , and until the end of charging,
The second transistor 80 remains off. That is, during the charging time of the second capacitor 82, both inputs A and B of the AND circuit 86 are at high level, and the output of the AND circuit 86 is at high level. As a result, a drive signal is output to the drive circuit 60 and the solenoid 40 is energized.

As described above, also in the second embodiment, since the lock is released for the fixed time T _{2 by} the OFF operation after the ON state of the operation switch 28 for the predetermined time T ₁ , the lock is illegally released. There is no. The internal configurations of the third level determination circuit 71 and the fourth level determination circuit 79 are not limited to those shown in the second embodiment, and as a result, the charging / discharging time of the first capacitor and the second capacitor. Should have the characteristics shown in FIG.

Further, in the first and second embodiments, the pachinko machine 10 is selected and described as the game machine, but the present invention is not limited to this pachinko machine 10 and can be applied to any other game machine installed in a game center or the like.

[Effects of the Invention] As described above, the unlocking control device for a gaming machine according to the present invention can prevent unauthorized unlocking with a simple structure such as a mechanical key and lock structure, and manages the gaming machine safely. It has an excellent effect of being able to.
