DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention uses a data-writing rod-shaped body such as a rod-shaped magnetic bar as a key in a gaming machine such as a slot machine. The present invention relates to a key device for a gaming machine such as a slot machine that can be opened and closed and unlocked.

[Conventional technology]

2. Description of the Related Art Conventionally, in gaming machines for playing various games such as slot machines and pachinko machines, most of the outer casings have a structure in which a lid is locked and unlocked by a mechanical lock.

In particular, when the gaming machine is a slot machine, the winning rate of the machine can be changed at any time by the store side, but when changing the winning rate, the lock on the front lid of the machine is inevitable. Open and operate the winning rate change switch etc. provided on the main board etc. inside the machine body.

[Problems to be solved by the device]

However, in a conventional game machine such as a slot machine, since the lock of the outer casing is a mechanical lock, there is a problem that a person who conducts an illegal act by opening an outer box with a so-called false key cannot refuse the rest.

This point can be prevented to some extent by using a high-grade mechanical lock, but in view of the high cost of the lock and the fact that it is still impossible to eradicate the illegal acts, it is a sufficient solution. I can't say.

There is also a problem that it is troublesome and troublesome to open the lid of the outer box one by one in order to change the winning rate or the like.

In view of this point, the inventor of the present invention has a practical application for a key device which is very difficult to make a false key first and therefore can prevent fraudulent acts using the false key almost completely.
Proposed as an issue.

An object of the present invention is to provide a key device which is a further improvement of the previously proposed key device.

[Means for Solving the Problems]

Therefore, in the present invention, it is extremely difficult to form a fake duplicating key. Therefore, it is possible to prevent most of the conventional fraudulent acts by using the fake duplicating key, and of course, it is easy to use and has sufficient durability. The purpose of the present invention is to provide a key device for a slot machine or the like, and its configuration is such that a gaming machine such as a slot machine has a door-like or lid-like body that can be opened and closed and is attached to its outer box. As locking / unlocking means, lock means for locking / unlocking by light or magnetic data is attached, and locking / unlocking means in the form of a rod with an appropriate cross section in which light or magnetic data is written is provided on the front side of the outer casing. Inserting portions for the rod-shaped data rewriting lock means having different cross-sectional shapes are respectively provided, and a reading portion for reading the data written in the rod-shaped locking / unlocking means at the tip of these insertion portions, This reading unit A control drive unit having a determination unit that determines read data and forms a signal for locking and unlocking the lock is provided, while a reading unit that reads the data written in the data rewriting lock means, A discrimination control unit for discriminating the read data and forming a signal for permitting data rewriting is provided, and is formed by operating a data setting switch provided on the outer box by the output of the discrimination control unit. It is characterized in that the rewriting unlocking data is written and stored in the discriminating unit and the rewriting unlocking data is written in the locking / unlocking means.

[Operation] Since the door of the outer box is locked and unlocked by the data written in the rod-shaped body, it is possible to prevent the unauthorized opening of the door by the false key. Further, since data is written on the tip end side of the rod-shaped body and the data reading portion is formed inside and inside the insertion portion, it is hard to be mischieved and durability can be secured. Further, since the unlocking data on the lock side can be easily set and changed at an appropriate timing, the above function is further enhanced.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of a slot machine equipped with an example of the key device of the present invention, and FIG. 2 is a block diagram in which a control system capable of unlocking data is added to the unlocking control system. FIG. 4 is a block diagram showing another example of the key device of the present invention having a control system for changing unlocking data and winning rate, and FIGS. 4 and 5 are perspective views showing examples of rod-shaped keys. is there.

In FIG. 1, 1 is an outer box of the slot machine, 2 is its front panel, which also serves as a front door. Reference numeral 3 denotes a hinge provided between the front panel 2 and the outer box 1, which is attached to the left side of the panel 2 here. Reference numeral 4 denotes a lock provided inside the outer box 1 on the opposite side of the hinge 3 between the outer box 1 and the front panel 2, and a mechanical key is conventionally inserted into a keyhole (not shown). By manually turning the key, a latch (not shown in the figure) that restrains the front panel 2 and the outer case 1 from being unable to open the door is opened, and the front panel 2 can be opened. It was In FIG. 1, 1a is a start button, 1b is a stop button, 1c is a reel, 1d is a game medium loading section, and 1e is a saucer.

However, in the present invention, in view of the fact that the conventional lock is illegally opened by a so-called false duplicate key, this key is replaced with a lock that is locked and unlocked by a rod-shaped key BK as shown in FIG. This point will be described below.

First, a so-called electric lock is used as the lock 4. This electric lock 4 has an actuator 4a such as a plunger having a latch 4b attached to its output end, as schematically shown in FIG.
And a control unit 4c that controls driving of the actuator 4a. Here, the drive control unit 4c outputs a signal for driving the actuator 4a in a direction of releasing the latch 4b when the unlocking signal op is supplied from the determination unit 4d, and the locking signal cl is supplied from the determination unit 4d. And a function of driving the actuator 4a in the locking direction of the latch 4b and outputting a signal for holding the position thereof.

The discriminating unit 4d outputs an unlocking signal op when the unlocking data preliminarily rewritably written therein and the data read by the reader 4e match, and the two data do not match, or one of It is formed so as to output the lock signal cl when there is only the data.

The reader 4e is the front panel 2 of the slot machine shown in FIG.
The unlocking data opd that is rewritably written in the inserted rod-shaped key BK is arranged behind the insertion hole 2a of the rod-shaped key BK formed in the inside of the machine.

Here, since unlocking data is formed by either light or magnetism, the rod-shaped key BK is formed by a member capable of writing these data. The rod-shaped key BK is formed to have a size of 15 to 20 cm as an example, and the data opd is written on the tip side thereof. Needless to say, the reader 4e and the discriminating unit 4d are also configured to support the types of unlocking data.
4g is a pilot lamp lighting circuit that lights the pilot lamp 4h when the discriminator 4d matches the data and outputs the unlock signal op.

In the present invention, the unlocking data written in the discrimination unit 4d is
It is rewritable.

Then, the master bar is inserted in the insertion hole 2b of the separately provided bar key.
When MB is inserted, the master data md written in this master bar MB is read by the smutter reader 5a provided inside the insertion slot 2b, and when the read data is authentic, rewriting A discrimination control unit 5b that outputs a drive control signal of the writer 5c for writing data is provided. On the other hand, the unlocking data setting switch 6a is provided and operated to cause the signal forming unit 6b to form a signal for setting another unlocking data, and this is written from the writer 5c to the determining unit 4d. Remember it. At this time, the old unlocked data opd previously written is sequentially erased by writing new data. When the content of the unlocking data opd is changed, the bar-shaped key BK also uses a different unlocking data opd recorded therein. Further, as will be described later, as the switch 6a, the start and stop buttons 1a and 1b provided on the panel are used in place of the switch 6a, or those provided separately on the outer surface of the outer box are used.

If the lock of the door 2 by the front panel of the slot machine is configured as in the above example, there is no possibility that the door is illegally opened by a mechanical false key. Also, the key is rod-shaped and you can insert it inside the machine and read the data,
Unlike the conventional method in which a reader is installed near the key insertion port, it has the advantage that dust etc. are less likely to enter and is not tampered with, and the unlock data can be rewritten and changed at appropriate times to protect against unauthorized unlocking. The nature is enhanced.

In addition, the master bar MB can be used also as a key for changing the setting state of the winning rate setting section provided inside the machine. Next, this point will be described with reference to FIG.

The winning rate of the slot machine is, for example, 6 levels
It is preset in about 10 levels, and the winning rate is appropriately changed within the above setting range on the store side.

Conventionally, this change is performed by opening the front door 2 of the slot machine and operating a key switch or the like on a main board forming a control section provided inside the machine body to change the winning rate of the winning rate setting section. Has been done.

However, in the conventional operation, the front door 2 has to be opened one by one, and in addition, the door may be illegally opened and the winning rate may be arbitrarily changed.

Therefore, in the present invention, the master bar MB is inserted and read out by the master reader 5a, and based on the signal, the discrimination control unit 5b.
When a coincident output is obtained in, the output of the discrimination control section 5b is supplied as a start trigger signal of a selection signal generating section 6c provided in the preceding stage of the winning rate setting section 7, and this trigger signal generates the selection signal. When given to the section 6c, the contents of the setting section 7 can be changed by operating the setting switch 6a for the winning rate selection signal generating section 6c to generate a selection signal. A numeric keypad or the like may be separately provided as the setting switch 6a, but the start button 1a and the stop button 1b of the machine are used instead.

Here, the signal written to the master bar MB may be shared with the data of the master bar for rewriting the unlocking data described above, but in order to avoid incorrect use, the master bar for changing the unlocking data should be used. It is desirable to use the master bar MB ₂ for changing the winning rate, which is recorded with another signal, separately from the MB.

When separate master bars MB and MB ₂ are used for their respective purposes, the discrimination control unit 5b is set with respective master data in advance, and the switching gates 5d, 5e are inserted by inserting the respective cards.
A switching trigger signal ct can be output to and the output path of the signal forming unit 6b can be switched to either side of the route of the writer 5c and the route of the selection signal generating unit 6c by the trigger signal ct. To do.

When using the common master bar for changing the unlock data and the winning rate, for example, when the setting switch 6a is operated, signals to be these switching signals are output to the switching gates 5d and 5e. It may be supplied by the operation of 6a.

Here, the master bar MB keeps the discrimination control unit 5b in the operating state while it is inserted into the insertion opening 2b,
When MB is removed, the operation of the control unit 5b is unlocked.

To prevent the keys (or bars) BK and MB from being inserted in the wrong direction, the front shape of the rod-shaped key insertion openings 2a and 2b is, for example, a semicircle, a triangle, or an appropriate shape. Different shapes such as isosceles polygons, each bar key BK, M
By making the cross-sectional shape of B match each of the insertion openings 2a and 2b, it is possible to prevent one rod-shaped body from being mistakenly inserted into the other insertion opening.

Although the above embodiment is for the slot machine,
INDUSTRIAL APPLICABILITY The key device of the present invention can be applied to any type of game machine such as a pachinko machine in which the front panel can be opened and closed as a door.

[Effect of device]

The present invention is as described above, and since a mechanical key is not used for the locking / unlocking means of the lock of the slot machine, it is possible to effectively prevent fraudulent acts, and to unlock without opening the front door at all. Since the lock data can be changed, it is extremely useful as a key device for a slot machine or the like.

Further, in the device of the present invention, since the cross-sectional shapes of the rod-shaped locking / unlocking means and the data rewriting lock means are different from each other,
Of course, it is easy to identify both means, and even if both means are used by mistake, they do not enter the insertion hole, so that misuse can be prevented.
