Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko machine control device that performs game control of a pachinko machine.
[0002]
[Prior art]
Conventionally, a circuit board on which a control device such as a ROM for controlling a game of a pachinko machine is arranged is housed in a board case for a pachinko machine. The pachinko machine board case (hereinafter, also simply referred to as a board case) is sealed so as not to be subjected to fraud such as changing a regular ROM to an unexamined ROM.
[0003]
Sealing here does not mean that it is completely isolated from the outside world, but in order to prevent fraud, the cover of the substrate case is not easily opened, or an equivalent structure is adopted. It means that In order to perform game control of a pachinko machine, it is necessary to supply electric power to a circuit board built in the board case or output a control result, so that the circuit board cannot be completely isolated from the outside world. Also, a pachinko machine usually determines whether or not to generate a jackpot depending on the timing when the game ball enters the start port. Therefore, it is indispensable to input a winning signal (a signal indicating that a game ball has entered a winning opening provided on the game board) to the circuit board.
[0004]
[Problems to be solved by the invention]
A board called a hanging board may be attached to the board, the winning sensor, the wiring connecting the winning sensor and the board, or the like. A hanging board is an unauthorized circuit board that makes it easy to obtain a jackpot.
[0005]
The hanging board searches for the winning timing at which the jackpot is generated in the pachinko machine, and issues a false winning signal. As a result, the control circuit in the board case erroneously recognizes that a start winning has occurred at the timing of jackpot, and generates a jackpot.
[0006]
It is also conceivable to perform the same fraud using sensor inputs other than those for detecting a start winning prize. For example, a circuit board that performs pseudo reproduction of a winning is provided in a sensor that detects a winning ball that is not a starting port, and a false winning signal is frequently generated. In this way, it is difficult to get a big hit in a short time like the above-mentioned hanging board, but by getting the winning ball constantly, aiming for a big hit without reducing (or gradually increasing) the possession ball Will be possible. In addition, in this case, since it is not necessary to find the jackpot timing, the configuration and control of the circuit board is simplified, and there is a problem that it can be easily realized.

DETAILED DESCRIPTION OF THE INVENTION
The pachinko machine control device according to claim 1 is configured to transmit a winning signal from the winning sensor as a change in light intensity to the control unit via an optical fiber.
Then, the light intensity monitoring means monitors the light intensity, and based on the monitoring result, the cheating detection means detects the occurrence of cheating. This monitoring may be performed periodically or only when a winning signal from the winning sensor is generated.
[0018]
This makes it difficult to insert the hanging board as compared to the case where the winning signal is transmitted as an electrical signal as in the prior art. In other words, in order to insert a hanging board into an optical fiber, it is necessary to configure the hanging board as one that generates a change in light intensity that matches a winning signal, not an electrical signal, which is very difficult. is there.
[0019]
Further, since the light intensity is regularly monitored by the light intensity monitoring means, if the light intensity changes due to the insertion of the hanging board, it is detected by the fraud detection means. Therefore, according to the pachinko machine control device of claim 1, it is possible to prevent the hanging board and the like from being connected.
Further, the pachinko machine control device according to claim 1, wherein the winning sensor is provided with an optical switch, a winning detection unit, and a switch control unit, and a game ball enters the winning opening by the winning detection unit. Is detected, the intensity of light emitted from the emission terminal of the optical switch is changed.
If it carries out like this, the intensity | strength of the light radiate | emitted when a game ball enters into a winning opening can be changed variously by the switch control part. For example, when a game ball enters the winning opening, the light intensity is reduced to about 50%, or the light intensity is constantly changed at a constant frequency, and when the gaming ball enters the winning opening, the frequency is changed. It becomes possible. In the latter case, a winning can be detected with little influence from noise.
[0020]
In the pachinko machine control device according to the second aspect, the winning sensor detects that a game ball has entered a start port provided in the game area. When a game ball enters the start port, the design of the display means provided in the game area is changed for a predetermined time. A jackpot occurs when the arrangement of the symbols displayed when the variation of the symbols is completed is a predetermined specific arrangement. In other words, winning at the start opening that requires winning in order to generate a jackpot is prevented.
[0021]
Therefore, the pachinko machine control device according to claim 2 is very effective in preventing fraud for the purpose of generating a big hit.
In the pachinko machine control device according to claim 3, an optical cable, a supply cable for supplying light of a light source arranged in a housing to the winning sensor, and a change in light intensity output by the winning sensor are controlled. And a transmission cable for transmitting to the network.
[0022]
That is, the detection of the winning signal is performed based on the intensity of light flowing through the optical circuit configured as a closed loop that reaches the winning sensor from the control unit and returns to the control unit. In this case, the hanging board must emit light having the same intensity as that of the light source in the housing. In addition, it is difficult to insert unless any part of the closed loop is disconnected.
[0023]
Therefore, according to the pachinko machine controller according to claim 3, Ru can be more difficult hanging from connecting the substrate.
[0026]
According to the fourth aspect of the present invention, at least the optical switch and the switch control unit are resin-molded.
In this way, it is possible to prevent an unauthorized operation with respect to the optical switch or the switch control unit or the destruction thereof.
[0027]
A known optical connector may be used to connect the optical cable and the control unit. However, in this case, there is a possibility that the hanging board is interposed in the optical connector portion.
According to the fifth aspect of the present invention, the optical cable and the control unit are connected within the housing. Since this casing is used in a sealed state, the optical connector cannot be removed unless the seal is released.
[0028]
Therefore, according to the pachinko machine control device of the fifth aspect , it is possible to make the illegal act more difficult.
[0029]
【Example】
Hereinafter, in order to further clarify the embodiment of the present invention, a preferred embodiment of the present invention will be described with reference to the drawings.
First, FIG. 1A is an explanatory diagram showing a pachinko machine substrate case 1 installed on the back side of the pachinko machine and the periphery of the substrate case 1. The substrate case 1 corresponds to the housing of the present invention. As shown in this figure, the start winning sensor 3, the normal winning sensors 5a and 5b, and the big winning opening sensor 7 are each a two-core optical cable 9. Connected at. Actually, detection signals from various sensors are input to the substrate case 1 in addition to these, but in the figure, only four of them are shown in a simplified manner. Reference numeral 11 denotes a lead wire for supplying power to each sensor, reference numeral 13 denotes an optical connector, and reference numeral 15 denotes power to the substrate case 1. The reference numeral 17 indicates a line for supplying the data, and an output line for outputting data and signals from the substrate case 1. The lead 11 supplies power to the start winning sensor 3, the normal winning sensors 5a, 5b, and the like.
[0030]
FIG. 1B shows the AA cross section of FIG. 1A around one optical connector 13. The optical connector 13 is inserted into a pair of optical sockets 19, and the optical connector 13 is extended from a hole smaller than the optical socket 19 formed in the lid 21 of the substrate case 1. A release hole 23 that is pushed when the optical connector 13 is removed from the optical socket 19 is provided in the lid 21 so that the optical connector 13 cannot be removed from the optical socket 19 unless the lid 21 is opened. Reference numeral 25 denotes a substrate on which the optical socket 19 is provided.
[0031]
An outline of the start winning sensor 3 is shown in FIG. The other winning sensors 5a, 5b, 7 (not shown) are configured in the same manner, and the processes described in FIG. As shown in this figure, the start winning sensor 3 includes an optical switch 27 that attenuates the intensity of light passing through the optical fiber, a switch control unit 29 that controls ON / OFF of the optical switch 27, and a magnetic sensor that directly detects a game ball. 31 is provided and these are resin-molded. The optical switch 27 allows light to pass through without being attenuated when no game ball is detected.
[0032]
The optical cable 9 is configured in a loop shape with an optical cable 9a, an optical switch 27, and an optical cable 9b. Here, the optical cable 9a corresponds to the supply cable of the present invention, and the optical cable 9b corresponds to the transmission cable. An optical transmitter 33 and an optical receiver 35 are connected to the optical socket 19. The optical transmitter 33 transmits or stops the light having a constant intensity according to the input electric signal. The optical receiver 35 converts the intensity of the received light into an electric signal and changes the intensity waveform. Is to shape. Reference numeral 37 denotes a connector that supplies power to the switch control unit 29 via the lead 11.
[0033]
FIG. 3 shows an outline of the winning detection circuit 38 located on the right side of the optical transmitter 33 and the optical receiver 35 in FIG. The winning detection circuit 38 includes an optical transmitter 33 (corresponding to the light source of the present invention), an optical receiver 35, an A / D converter 39 that discretizes the light intensity output from the optical receiver 35 in 256 stages, An input port 41 for receiving the waveform output from the optical receiver 35 and the output value of the A / D converter 39, a hybrid IC 43 (corresponding to a control unit of the present invention) incorporating a CPU, ROM, RAM, and the like, and a hybrid IC 43 EEPROM 45 for storing data processed in the above in a non-volatile manner and an output port 47 for outputting data instructed by the CPU to the outside. Note that the input port 41, the EEPROM 45, and the output port 47 are connected to the hybrid IC 43 by a bus 49. The signal sent from the optical receiver 35 to the input port 41 is obtained by processing the waveform of the result of the light intensity modulation performed by the switch control unit 29 in response to the detection of the game ball by the magnetic sensor 31. It is sent as a signal. On the other hand, the signal sent from the A / D converter 39 to the input port 41 is data relating to the intensity of light received by the optical receiver 35, which is transmitted from the optical transmitter 33 and sent to the optical receiver 35. A steady electric signal (not affected by whether or not a game ball is detected by the magnetic sensor 31) indicating only the intensity of the light that has returned is sent. The data transmitted from the output port 47 to the optical transmitter 33 is an ON / OFF signal for instructing transmission / stop of light.
[0034]
A schematic flowchart of the light intensity management process executed by the CPU in the hybrid IC 43 is shown in FIG. A program for realizing this processing is stored in the ROM in the hybrid IC 43 and is activated at regular intervals (for example, 10 msec). When this process is started, first, in step (hereinafter abbreviated as S) 100, it is determined whether or not the optical transmitter 33 is ON (that is, light is being transmitted). If it is not ON, nothing is done and this process is terminated. If the optical transmitter 33 is ON, the process proceeds to S110, and the current light intensity data is read from the A / D converter 39. In subsequent S120, it is determined whether or not the light intensity is stable. Note that a state in which the light intensity is not stable even though the optical transmitter 33 transmits light of a constant intensity occurs immediately after the optical transmitter is turned on. An example of this is shown in FIG. FIG. 5A is a graph in which the vertical axis represents the light intensity input from the A / D converter 39 to the input port 41 and the horizontal axis represents the passage of time. In this graph, t <t1 indicates a state where the strength is not stable, and t> t1 indicates a stable state.
[0035]
Returning to FIG. Since it is not desirable that the light intensity is not stable, this process is terminated in such a case. If stable, the process proceeds to S130, and the light intensity stored in the EEPROM 45 is compared with the current light intensity by the previous main processing. Then, it is determined whether or not the light intensity has changed by 5% or more (S140). If the light intensity has not changed, it is considered normal. Therefore, the process proceeds to S150, the current light intensity is stored in the EEPROM 45, and this processing is performed. Exit. On the other hand, if the light intensity has changed by 5% or more, it is considered that some unauthorized manipulation (for example, a hanging board is interposed in the optical cable 9a or the optical cable 9b) has been performed. An abnormality occurrence signal is output and this process is terminated. The abnormality occurrence signal is output to a computer (hall computer) that manages the pachinko hall in which the pachinko machine is installed. Thereby, the occurrence of abnormality can be known by the hall computer. S110 of this process corresponds to the light intensity monitoring unit of the present invention, and S130 and S140 correspond to the fraud detection unit of the present invention.
[0036]
Detection of a start winning prize not shown in this flowchart will be described with reference to FIGS. 2, 5B, and 5C. When the magnetic sensor 31 detects the passage of the game ball (that is, the start prize), the switch control unit 29 turns on / off the optical switch 27 at a frequency of 10 kHz for 100 msec. This is shown in FIG. 5 (b). This figure shows the change in the light intensity passing through the optical cable 9b when the light intensity is taken on the vertical axis, the time is taken on the horizontal axis, and a game ball passes at time t2. As shown in the figure, when the game ball passes at time t2, the light intensity is attenuated to about 50%, and until the time t3 after 100 msec, the light intensity is returned to 100% at a frequency of 10 kHz. It is attenuated to about%. The change in light intensity is converted into an electrical signal by the optical receiver 35, and the waveform is shaped as shown in FIG. 5C. When it is detected that the waveform has changed in this way, it is determined that there has been a start prize.
[0037]
A typical example of the above-mentioned hanging board is one that artificially generates this waveform change. By generating this waveform change at a specific timing, the winning detection circuit 38 is misrecognized and a jackpot is generated. However, when the hanging board is connected in this way, the light intensity received by the optical receiver 35 changes from the original light intensity. By detecting this change in S130 and S140 in FIG. 4, the interposition of the hanging board is detected.
[0038]
With this configuration, the winning sensors 3, 5a, 5b, and 7 and the board case 1 are connected by the optical cable 9, so that it is extremely difficult to interpose the hanging board. That is, when the detection signal is transmitted and received by the conventional electrical signal, the optical cable 9 is cut, the required end face treatment is performed, and the optical connector is connected to the case where the electric wire is exposed and the terminal is connected. Need to connect. Therefore, it is difficult to connect the hanging board. Even if a hanging board is interposed in the optical cable 9, the change in the light intensity is monitored at regular intervals, so that this can be reliably detected.
[0039]
Further, since the optical connector 13 is prevented from being detached from the optical socket 19 unless the lid 21 is opened, it is difficult to interpose a hanging board between the optical connector 13 and the optical socket 19.
As mentioned above, although the Example of this invention has been demonstrated, this invention is not limited to this Example at all, and if the gist of this invention is satisfy | filled, it can be implemented in various aspects. Not too long.
[0040]
For example, the switch control unit 29 is supplied with power via the lead 11, but may be battery driven. That is, the switch control unit 29 is configured to be driven by a small battery such as a button type battery, and the battery is molded together with the switch control unit 29, the optical switch 27, and the like. In this case, the battery is disposable, but the wiring of the winning sensor 3 is simplified.
[0041]
Alternatively, a part of the light supplied by the optical cable 9a may be used for photovoltaic power generation to cover the power. Further, instead of the optical switch 27, switching may be performed using an optical semiconductor driven by a non-power source.
In addition, the light of the optical cable 9a is radiated to the passage path of the game ball entering the winning opening so that the light can be received by the optical cable 9b. Then, the game ball may block the optical path to detect the decreased light intensity and detect the winning. This is illustrated in FIG. In this way, the winning detection device can be configured very simply using the optical signal. In addition, since there is no electrical configuration in the vicinity of the game board, the game board is resistant to illegal games using electromagnetic waves.
[0042]
Moreover, although the optical transmitter 33 is provided in the pachinko machine substrate case 1, it may be provided in the start winning sensor 3 and the normal winning sensors 5a and 5b. Even if power is supplied from the lead 11 and light is transmitted to the optical switch 27 via the optical switch 27, substantially the same effect can be obtained.
