2. Description of the Related Art Conventionally, Japanese Unexamined Patent Publication No.
A pachinko machine lock device provided by Japanese Patent Application Laid-Open No. 28283 / 11-290531 is known. These have been recognized as effective locking devices for individual pachinko machines installed in halls.

In order to facilitate understanding of the basic configuration focusing on the locking device, the general pachinko machine 1 includes a pachinko machine front door 20 attached to the pachinko machine frame 2.
For example, FIGS. 4 and 5 are examples. FIG. 4 is a perspective view of a main part showing a state where the pachinko machine front door 20 attached to the underframe 2 is partially opened in a normal pachinko machine, for example. FIG. 5 is a side view of a main part for explaining a hook used for a locking portion of the pachinko machine front door 20 and a stopper portion attached to the underframe.

In order to open the pachinko machine front door 20 of the pachinko machine 1 from the underframe 2, a key 4 is inserted into a key hole 3 provided in the pachinko machine front door 20 and rotated. This locking device is a known means generally used. The front door 20 is provided with a hook 6 at the tip of an engaging projection 16 at the movable portion of the pedestal 5, and the underframe 2 is provided with a stopper 8 for restricting the return of the hook 6.

A more specific unlocking operation is performed by inserting the key 4 into the keyhole 3 in the base door 20 and rotating the key. As shown in FIG. 2, at the time of locking, the movable side spring hook 3 attached to the movable portion 34 in the longitudinal direction of the pedestal 5.
4 is locked by the spring 7 mounted between the fixed side spring hooking portion 12 in the fixed portion 35 of the pedestal 5. At this time, the locking operation is performed by pulling out the key 4 from the keyhole 3, and even if the key 4 is not pulled out, the hook 6 and the stopper 8 of the underframe 2 are engaged and held by the restoring force of the spring.

At the time of unlocking, the key 4 is inserted into the keyhole 3 and rotated, whereby the movable portion 34 that has been pressed down with respect to the fixed portion 35 is lifted upward, and the engaging projection 1
The hook 6 at the distal end of the hook 6 is lowered. As a result, the engagement between the hook 6 and the stopper 8 of the underframe 2 is released, and the pachinko machine front door 20 is opened. Note that the above operation is an example, and some pachinko machines have a reverse operation.

Further, the pachinko machine front door 20 is closed by the underframe 2.
By pushing the door 20 in front of the pachinko machine, the hook 6
The engaging projection 16 is pushed down by the stopper 8, and when it is further pushed in, the engaging projection 16 is disengaged and the hook 6 is lifted up by the force of the spring 7 so that the hook 6 can be automatically closed. In addition, this door does not require insertion rotation of the key only by pushing it in. The locking device having such a configuration can be easily opened with a double key or the like, and the above-mentioned application has provided specific means for solving the problem as a measure for avoiding the danger of fraud.

[0008] However, in these conventional techniques, the pachinko machine installed in the hall is not sufficient in terms of security due to an illegal operation of a key or the like. Occasionally, the pachinko machine is easily unlocked by unlocking from a gap in the machine or by other means.

For this reason, the pachinko machine has comprehensive measures for securing the security of the entire hall together with the individual locking and locking devices, and new fraud prevention such as unauthorized key operation, unlocking with a duplicate key, and unlocking by other means. There is a growing need to take measures. On the other hand, a simple lock mechanism, such as a wire lock mechanism that can be operated from the outside of the pachinko machine, eliminates the need for countermeasures for key matching and management, and saves energy by remote operation that can be managed individually or collectively. There is a need to solve the problem as a pachinko machine locking lock device that has achieved cost reduction by the above.

[0014]

Embodiments of the present invention will be specifically described below. Referring to the drawings, FIG. 1 is a schematic diagram showing a basic configuration of a pachinko machine lock lock device (hereinafter, referred to as a lock device in an embodiment of the present invention), and more specifically, a pachinko machine. FIG. 2 is a schematic view of a lock and lock device provided with a wire and a means for winding the wire with a motor in a state of being mounted on a ladder used for lock and lock of the pedestal; FIG. 2 is a table similarly controlled by the lock and lock device; It is the schematic diagram which omitted a part of Sao. FIG. 3 is a block diagram showing a basic configuration of a control circuit diagram used for controlling the pachinko machine lock lock device.

The details will be described below. The platform rod functions as a part of a lock and lock device used for unlocking and opening and closing the lock. In particular, the locking hook of the pachinko machine main body attached thereto can be locked or unlocked by changing the position of the wire driven by the locking and locking device.
In this state, the lock is opened and closed with the key for unlocking or locking the lock device, so that the pachinko machine can be individually or collectively managed by using a control circuit described later, thereby achieving cost reduction by labor saving by remote control. Things. As a result, only the unlocked table can be unlocked by key operation and the table door can be opened from the table frame.

FIG. 1 shows an embodiment of a lock device according to the present invention. The lock lock device 10 is used for controlling a lock lock paddle 5 mounted on various pachinko machines and pachislot machines (hereinafter referred to as a pachinko machine, but should be understood as a concept including the latter). The operation is controlled by a control circuit 21 described later. Therefore, it can be used as a novel locking and locking device including application to a pachinko machine currently used.

FIG. 2 is an explanatory view in which a part of the pedestal 5 shown in FIG. 4 of the prior art is omitted. The lock is opened and closed by a key operation for unlocking or locking the lock device by a pachinko machine manufactured by each company, and the basic operation is similar. As an outline of the structure, the overall length is about 38 cm, and there is an opening or closing key insertion end (not shown) at a substantially central portion in the longitudinal direction.
By inserting and rotating the key here, the hook 6 rotates about the rotation shaft 32 in the direction of the arrow in the figure. As a result, the hook 6 releases the engagement of the stopper 8 shown in FIG. 5, and the base door opens.

More specifically, the movable part 3 is operated by key operation.
When the hook 4 is displaced upward with respect to the fixed portion 35, the hook 4 is pulled up by the engagement shaft 33, and the hook 6 is lowered in the direction of the arrow. When the key is returned, the movable portion 34 is lowered by the spring 7 mounted between the movable-side spring hook portion 11 and the fixed-side spring hook portion 12, and the hook 6 returns to the position shown in the figure. This puts the lock in the locked state. By providing a wire mechanism described below at the position of the spring 7, it is possible to restrict the door opening by a key operation from the front door.

FIG. 2 shows one of the hooks 6. A similar hook 6 is generally a pair at the top of the figure as a whole, and performs the same operation in cooperation with the other. Further, the same effect can be expected in the present invention even when only one type is used depending on the model. FIG. 1 shows FIG.
The state of cooperation between the platform 5 and the lock device shown in FIG. The wire 13 of the locking device is connected to the pedestal 5 and its control is the point.

The lock 10 is provided with a worm 17 of a worm gear, a worm wheel 18 and a motor 19 for driving the worm. The motor 19 rotates the worm gear by the control circuit 21 to wind the wire 13 connected to the pedestal 5 and open it. Here, only the motor drive will be described, but other drive means are not excluded. For example, a solenoid, a rotary solenoid, or the like can be used instead of the motor. The wire material used was 0.9 mm in diameter, and the material used was stainless steel wire, but the material is not limited to this. For example, a diameter of 1.0 m
m piano wire can be used. A part of the wire 13 is attached and fixed to the shaft portion of the worm wheel 18 in advance. Further, the rotation is performed to perform the winding. These devices are usually installed outside the housing of the pachinko machine.

After the tip of the wire 13 is turned over through the pulley of the fixing part 14 in the case of the pachinko machine, the wire 13 is hooked on the wire end fitting 9, and the tip of the stand 5 is fixed. It is attached to the movable side spring hooking section 11. A stopper is provided between the movable side spring hooking portion 11 and the fixed side spring hooking portion 12 of the pedestal 5, and a hook 6 attached to the movable side of the pedestal 5 is attached to the underframe 2. 8 is pulled by the spring 7 and engaged at the time of locking. A flexible outer wire 15 that covers the peripheral surface between the worm wheel 18 and the movable-side spring hook portion 11 of the pedestal 5 is attached to the wire 13. This fixing part 14 was installed in the inner wooden part of the base door near the lower hook 6 of the base 5. The pulley for the wire 13 was fixed to this wooden part with a screw.

The lock device 10 controls the winding of the wire 13 by a control signal from a motor drive power cable 30 and a motor control signal input connector 31. Next, as a method of attaching to the pachinko machine, the lock locking device 10 is installed on the outer casing of the pachinko machine. This is a request from the legal and regulatory considerations to prevent unauthorized modification of the device inside the pachinko machine housing. Since it is only necessary to connect the tip of the wire 13 to the pedestal to the inside, there is a demand for failure measures and regulations. The effect which matched also was recognized.

A description will be given of the wire setting as an installation preparation in this configuration. The distal end of the wire 13 is circulated around a fixing portion 14 provided on a wooden frame to which the pedestal 5 (not shown) is fixed to invert the wire, and the distal end of the wire 13 is hooked on the movable spring hooking portion 11 of the pedestal 5.

From this stage, in order to bring the wire 13 into a pulled state, the motor is rotated forward by a control circuit, which will be described later, so that the wire is gradually pulled into the locked state. As a result, the hook 6 of the pedestal 5 is fixed in a state in which the wire 13 is pulled, and the hook 6 is engaged with the spring 7 so that a lock state cannot be opened by a key operation. Although it functions as a so-called regulated state that cannot move freely, the present invention uses the term "immobile" as this state, but should be understood as having such a meaning.

Similarly, in order to loosen the wire 13, that is, to make the wire 13 free, the motor by the control circuit is driven in reverse for about 0.25 seconds to loosen the wire by about 15 mm. As a result, the movable portion of the pedestal can move freely with the wire 13 relaxed while the hook 13 is engaged with the spring 7 but the hook 6 can be moved by the key operation. It is in an unlocked state on the control device which can be unlocked.

Further, in order for the control circuit 21 to return to the locked state, that is, the state in which the hook 6 is entangled by the wire 13, the hook 6 is engaged with the stopper 8 by rotating the motor forward for about 1 second. This is a so-called locked state on the present control device which cannot be unlocked by a key operation on the front of the pachinko machine. As a result, in a state where the movable part 34 and the fixed part 35 of the pedestal 5 are integrated, so-called integral operation is restricted by the key operation of the movable part 34, and the fixed state is maintained.

Here, it should be noted that a time difference between unlocking and locking on the control device is provided.
25 seconds, the latter about 1 second. Therefore, it is necessary to increase the size of the latter in order to avoid the so-called device, variation during operation, and to ensure safety during use. In the embodiment, it is set to about 4 times, but preferably set to about 1.2 to 10 times. It is desirable to do.

FIG. 3 is an embodiment of a block diagram of a control circuit of the lock device according to the present invention. Note that a specific circuit is not shown in this block diagram. In addition, control connection resistances such as a capacitor, an IC, and a transistor in the circuit, a protection diode, and other components are omitted and not shown in the figure. Should work.

A general power supply (not shown) can be used as the power supply, and a DC voltage is supplied to a control circuit, which will be described later, via a rectifier circuit by a separate AC power supply circuit for driving the motor. In order to facilitate understanding of the following description, the key operation for unlocking and the operation of the platform 5 will be described. The normal unlocking operation is performed by a key. The spring 7 between the movable side spring hooking section 11 and the fixed side spring hooking section 12 extends, the hook 6 rotates rightward, and the pachinko machine front door 20 is released from the underframe 2. From the door is opened. As described above, the key operation means the release of the fitted state between the hook 6 and the stopper 8.

Referring to the block diagram of FIG. 3, the open signal input terminal 22 and the close signal input terminal 23 are connected to a control command circuit 26 via photocouplers 24 and 25, respectively, and function as an operation command circuit based on the signal input. I do. The photocouplers 24 and 25 enable insulation type control by collective control commands. As a whole, there are several
The present invention can be applied to up to about 0 lock / lock devices, and when there are a plurality of lock / lock devices, they simultaneously function as a large number of lock / lock devices according to a command from here on.

The output from the photocoupler is transmitted to the control command circuit 2
6 is input. Here, it is composed of a command circuit capable of judging an open signal input and a close signal input, detecting an erroneous signal in response to an overlapping operation and an operation error, initial setting, and resetting. further,
After confirming the input signal, a motor drive output is performed by the motor drive signal generator 27 as a control command. In addition to a forward / reverse rotation command to the motor 19, the motor 19 is connected to an output terminal 29 via an overcurrent prevention and overvoltage prevention element 28 when the motor is stopped. The output terminal 29 is connected to the motor 19 and the motor 19 is controlled.

The operation according to the close signal command is as follows. In this case, the motor 19 rotates in the direction in which the wire 13 is wound. The worm 17 rotates, the worm wheel 18 turns clockwise in the figure, and the wire 13 is pulled.
1 is fixed to the right in FIG.

As a result, the spring 7 between the movable-side spring hooking portion 11 and the fixed-side spring hooking portion 12 is not extended by key operation for unlocking, and the hook attached to the movable portion of the pedestal 5 is not extended. 6 cannot move, and the hook itself cannot rotate right. Therefore, the hook 6 does not come off the stopper 8 and the pachinko machine front door 20 does not come off.
Does not open from the underframe 2. Therefore, as long as the wire is kept in this state, the hook 6 is rotated rightward by the key operation and does not come off the stopper 8, and the pachinko machine front door 20 is not opened from the underframe 2. In the present invention, the movable side spring hooking portion 11 by this wire is used.
Is important, and the worm 17, the worm wheel 18, and the control circuit can achieve this fixed state.

The details of the circuit setting up to the stop state of the motor will be described. In the above-mentioned motor drive, it is usually about one second at the stage when the wire is pulled completely, but if the motor is stopped in a state where the wire is pulled, an overcurrent occurs.
In order to prevent the coil from burning, a motor drive signal generator 27 is provided with an overcurrent preventing element (not shown). Further, the distance until the wire 13 is pulled up depends on the structure of the pedestal 5 used for each pachinko machine, but generally, about 5 mm to 15 mm is appropriate.

Therefore, in the lock device 10 of the present invention, this degree of pulling is taken into consideration with respect to the rated output of the motor, the size of the worm gear, and the motor driving time.
More specifically, there is play of the wire 13 for about 0.25 seconds of the motor driving time, and the winding amount of the wire by the motor should be set to a degree exceeding the play. At the same time, if the wire is pulled for about one second, the motor will almost stop. This time difference is extremely important.

When the motor stops, the motor inflow current is 1
This is about 0 times, which causes a problem such as failure due to burning of the coil and excessive power consumption even if failure does not occur. In this embodiment, the minimum driving time of the motor is set to 0.3 seconds or more, preferably 0.5 seconds to 1 second. This corresponds to the winding time and the stopping time by the motor. Therefore, the motor stop time depends on the motor drive time. For example, if the motor is driven for 1 second, it should be selected within 0.7 seconds, preferably in the range of 0.2 to 0.7 seconds. . Thus, the amount of movement of the wire is selected based on the distance between the movable spring hook 11 and the fixed spring hook 12, play, and the like. Usually, it can be provided as a device with a value that matches the structure and size of the pachinko machine installed in the hall.

The operation for the open signal input is as follows. In this case, basically, the wire 13 is relaxed. The motor 19 rotates in the reverse direction of the closing signal, the worm 17 rotates, and the worm wheel 18 rotates the worm 1
In FIG. 1, the wire 13 is relaxed so as to be discharged, and the movable side spring hooking portion 11 having the fixed portion 14 as a pulley is used.
Is in a state where it can freely move to the left in FIG.

In this case, the circuit setting will be described in the same manner until the motor stops. As described above, when the motor is driven, the motor starts reverse rotation in the direction in which the wire is discharged from the stage where the wire is fully pulled. The motor driving time in this case is about 0.25 seconds. Below this, the wire is less relaxed and the movable part 34 of the pedestal 5 cannot be completely moved, so that the spring 7 cannot return to the original position. Further, in a state higher than this, since the amount of discharge of the wire becomes large, the time during the normal rotation of the motor becomes long. Also here, the distance until the wire 13 is fully pulled also depends on the structure of the pedestal 5 used for each pachinko machine, but it is generally 5 mm to 15 mm.
The degree is appropriate.

As a result, the spring 7 between the movable side spring hooking portion 11 and the fixed side spring hooking portion 12 can be extended by key operation for unlocking, and the hook 6 can be rotated clockwise. For this reason, the hook 6 is released from the stopper 8 for the first time by the key operation for unlocking, and the pachinko machine front door 20 is released.
Is opened from the underframe 2. Therefore, as long as the wire continues in this state, the state in which the hook 6 can be rotated rightward by the key operation and can be detached from the stopper 8 continues.

It is also possible to select an option to activate the reset function in the apparatus after a certain period of time due to the risk of unauthorized operation due to the wire remaining in this state. By this option selection, an operation in which the hook 6 does not rotate rightward and comes off the stopper 8 by a key operation is avoided.

Further, the fail safe of the present invention will be described. After the closing signal is input, as described above, the wire is wound up and the hook 6 and the stopper 8 of the platform are always engaged. However, in the case where the wire winding changes due to wire play, elongation over time, disconnection, etc., the present invention does not deny setting of winding replenishment by motor driving every specific time. .
These tasks can be set and executed on a schedule and wire monitoring sensors can be installed to ensure higher security.

[0042]

According to the present invention, it is possible to collectively manage the locks of a large number of pachinko machines installed in a hall. As a result, it is possible to provide a key lock mechanism for ensuring security against unauthorized operations in key operations. As a result, the countermeasures against fraudulent acts using the duplicate key and the trouble of the manager can be saved.

For the first time, the lock can be unlocked individually by remote control of the lock. Furthermore, since it can be easily mounted on pachinko machines that are currently on the market, mass supply and demand has been made possible, and costs have been reduced.

As described above, by providing the individual key lock mechanism which is collectively managed, the pachinko machine lock which can reduce the cost of key management and the person in charge of management by remote control and achieve cost reduction by remote control. Can be provided as a device.

Still further, only the ladder provided for locking and locking the pachinko stand and a portion attached to the movable part of the ladder at the end are arranged in the pachinko stand, and the other parts are placed outside the casing of the pachinko stand. Since it is composed of a wire that allows the other end to be wound by the arranged winding drive source, especially in the case of a closed box such as a pachislot machine, when the lock device of the present invention fails, The disadvantage that the box cannot be opened from the outside can be avoided.
