[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pachinko machine equipped with a winning device equipped with a winning ball detector having a sensor section whose electrical physical quantity changes as winning balls pass. be.

[Prior Art] In recent years, in the winning device of a pachinko machine, a winning ball that has won a prize is detected by the winning device, and other devices are operated.
Alternatively, there is a winning device equipped with a winning ball detector to count the number of winning balls that have won. The winning ball detector included in such a winning device has reliability of operation,
In view of various advantages such as good responsiveness and durability, the mainstream is that which has a sensor section whose electrical physical quantity changes as the winning ball passes.

[Problems to be Solved by the Invention] By the way, some players play illegal games by taking advantage of the properties of the above-mentioned winning ball detector. For example, you can generate electromagnetic waves with a transceiver, etc., and have the influence of the electromagnetic waves on the winning ball detector to cause it to malfunction as if a winning ball has occurred, or you can bring a permanent magnet close to the front of the pachinko machine to detect the winning ball detector. There was a risk that this would cause the game to malfunction as if a winning ball had occurred, which would have a serious impact on the game. Furthermore, such a risk may also be caused by naturally occurring electromagnetic waves.

The present invention was made in view of the above-mentioned problems, and its purpose is to provide a pachinko machine that does not affect the progress of the game even if the winning ball detector malfunctions due to the influence of external electromagnetic waves or magnetism. The aim is to provide the opportunity.

[Means for Solving the Problem] In order to achieve the above-mentioned object, a pachinko machine according to the present invention includes: a winning device that can accept a batted ball and make it into a winning ball; a winning ball detector having a sensor portion whose electrical physical quantity changes as the winning ball passes through the winning ball; It is characterized by comprising: a fraud detector having the same operating principle; and detection output determining means for determining the output of the winning ball detector to be invalid when there is an output of the fraud detector. [Function] When a winning ball enters the winning device and passes through the winning ball detector, the winning ball is detected by detecting a change in the electrical physical quantity in the sensor section during the passage. By the way, if external electric waves (i-waves, magnetism, etc.) affect the winning ball detector and cause it to malfunction, the ball will be placed in a position that is not related to the flow path of the winning ball, which has the same operating principle. A built-in fraud detector may also be activated. In this case, when there is an output from the fraud detector, the output from the winning ball detector etc. is presumed to have been fraudulently emitted by external electromagnetic waves or magnetism, and is determined to be invalid. In other words, even if the winning ball detector malfunctions due to electromagnetic waves, free magnetism, etc., it is determined that the winning ball detector did not operate, so the game can proceed without any influence.

In addition to the jackpot lamps 13a and 13b, the gaming area 7 is provided with an operating lamp 54 (not shown; however, shown in FIG. 4) that operates in accordance with various gaming conditions.

An upper tray 15 is fixed to the surface of the front plate 5 for storing the paid prizes and supplying the ball to the firing position.
At the front of the front frame 2 below the upper tray 15, an operating handle 16 for adjusting the rebound force of the ball and a lower tray 17 for storing prize balls that cannot be stored in the upper tray 15 are attached. Furthermore, a speaker 19 is provided behind the lower tray 17 to generate sound effects corresponding to various game conditions.

Next, with reference to FIG. 1, the configuration of the variable winning device 20 as a winning device will be explained. The variable prize winning device 20 is
It has a mounting board 21 for mounting on the game board 6,
A rectangular winning opening 22 is opened in the mounting board 21. An opening/closing door 23 is supported on both sides of the lower end so as to open and close this winning opening 22. This opening/closing door 23 is opened/closed by the solenoid 52 described above. Further, at the rear of the mounting board 21, an enclosing frame 24 is protruded so as to surround the entry opening 22, and the enclosing frame 24
A guiding gutter 25 is provided in the opening/closing door 23 for guiding the winning balls received by the opening/closing door 23 and winning. Induction gutter 25
The exit 26 is designed to allow winning balls to pass through one by one, and faces a large winning hole winning detector 30a that detects the passing winning balls. This big winning opening prize detector 30a is for counting all the winning balls received by the opening/closing door 23.

In addition, at the center of the lower edge of the winning opening 22, a pair of partition members 2 are provided.
7a, 27b are projected rearward, and the partitioning members 27a,
A winning opening 28 is formed at a position sandwiched between the partition members 27b, and winning openings 29a and 29b are formed on the outside of the partition members 27a and 27b. (2) A winning prize detector 30 faces the winning opening 28, and when this is activated, the opening/closing door 23 is repeatedly opened as described above.

Further, in the variable winning device 20, a fraud detector 30b, which constitutes a main part of this embodiment, is installed at the lower side of one side of the surrounding frame 24, which is a position other than the flow path of winning balls. Since this fraud detector 30b is not for detecting winning balls, it is located at a different position from the illustrated embodiment, and even if the opening/closing door 23 is opened and a winning ball is generated, the winning ball will pass through. It suffices if it is installed in a position where it cannot be played, that is, in a position other than the flow path of the winning ball. In addition, the fraud detector 30b includes the seven winning prize detectors 30 and the big prize winning opening prize detector 30a.
It has the same structure as , and has a sensor section whose electrical physical quantity changes based on the same operating principle. In addition,
The back surface of the surrounding frame 24 of the variable prize winning device 20 is covered with a lid cover (not shown). Here, the structure of the winning ball detector 30 (including 30a and 30b) will be explained with reference to FIGS. 2 and 3. The appearance of the winning ball detector 3° is as shown in FIG. It has a frame 31 with a passage hole 33 formed in its front end, and a ball detection circuit is built into its base 32. A coil 35 (FIG. 3) constituting a sensor section is embedded in the side wall of the passage hole 33. Two wires (lead wires) 39a and 39b are drawn out from the frame 31 through which current flows into and out of the ball detection circuit. The winner's prize ball detector 30 is supplied with power from a lead wire 39a, and a winning detection signal is output from a signal line 39b.

The ball detection circuit built into the base 32 is configured as shown in FIG. 3, and an inductance made of a coil 35 is connected to an oscillation circuit 36. An oscillation circuit 36, a detection circuit 37, and a waveform shaping circuit 38 are provided as a sphere detection circuit. Control circuit 4 connected to the prize ball detector 30
The signal processing circuit 44 on the 0 side, which will be described later, includes a series circuit of a resistor R1 and a resistor R2 to which the lead wire 39a is connected, a transistor Tr that inputs the signal at the dividing point, and an inverter V that outputs a large voltage at its collector terminal. Consists of. and,
Lead wire 39a is connected to a 24V power supply, and lead wire 3
9b is grounded through a series connection of a resistor R1 and a resistor R2. In other words, the winning ball detector 30 according to this embodiment
is used as a two-terminal element, and the resistance between the two terminals changes binary based on the detection of a winning ball.

In the state connected to the signal processing circuit 44 on the control circuit 40 side as described above, the winning ball detector 3o operates as follows. When the winning ball does not pass through the coil 35, the oscillation circuit 36 oscillates at a predetermined frequency, but when the winning ball passes through the coil 35, the loss due to the eddy current induced in the winning ball becomes large. Then, the oscillation circuit 36 stops oscillating. The signal S1 is outputted to the detection circuit 37, and its envelope is detected, and the detected signal S2 is manually input to the waveform shaping circuit 38 and shaped into a rectangular wave. Therefore, the output S3 of the waveform shaping circuit 38 is at a high level in the normal state when no winning ball is detected, and becomes low level when a winning ball is detected. A signal S4 at the connection point between the resistors R1 and R2 is proportional to the signal S3, and the transistor Tr is turned on or off depending on the signal level of the signal S4.

Since the collector signal of the transistor Tr is inverted by the inverter IV, its output signal S5 corresponds to the signal S3. Turn the winning ball on and off in this way
It can be taken out as a signal.

Since the winning ball detector 30 exhibits the above-described structure and function, for example, when a player uses a transceiver or the like,
If an electromagnetic wave is generated externally using a device capable of generating n-waves, an induced current may be generated in the coil 35, which may cause the ball to malfunction as if there were a winning ball. At this time, there is a high possibility that all the winning ball detectors 30, 30a, 30b provided in the variable winning device 20 also operate. That is, in this embodiment, the fraud detector 30b not related to winning balls also operates. By the way, this fraud detector 30b is connected to a control circuit 40 that controls the game, as shown in FIG.

Here, to explain the control circuit 40, the control circuit 4
0 has a microcomputer 41 as a control center, and the microcomputer 41 includes an external ROM 42,
An external RAM 43 is connected. The microcomputer 41 also includes the various detectors described above, namely the fraud detector 30b and the (starting) winning ball detectors t8a to 18c.
, the big prize B prize detector 30a, and the human input signals from the V person prize detector 30 are processed by signal processing circuits 448 to 448 having the above-mentioned configuration.
44f. Further, an audio signal is output from the microcomputer 41 to the speaker 19 via a speech synthesis circuit (SSG) 45. Further, the drive device 51, for example, the solenoid 52, is connected via the driver 46.
, the jackpot lamp 13a, the f3b%V lamp 53, the operation lamp 54, and the like. The microcomputer 41 includes a clock generation circuit 47, a frequency divider 48 that divides the frequency of the pulse from the clock generation circuit 47 to execute external interrupt processing for a fixed period of time, and a reset signal generation circuit 49 for initialization. , and microcomputer 4
A power supply circuit 50 for supplying power to each of the devices 1 and 1 is connected to each of the devices. Note that fixed-time external interrupt processing that is processed based on the external interrupt signal output from the frequency divider 48 includes timer processing, sound/lamp processing, detector manual processing, and the like.

Of the operations of the control circuit 40 configured as described above, the detector input process is extracted from the fixed-time external interrupt process executed based on the external interrupt signal output from the frequency divider 48, and FIG. Refer to and explain. After the initial setting, the microcomputer 41 executes the fixed-time external interrupt program shown in FIG. 5 every time the external interrupt signal output from the frequency divider 48 is input. First, step S1
0, the state signals S1, S2, S3, S4 of the switch group are read. These status signals are composed of negative logic, and when the level is low, the switch is in the ON state.
This indicates that a winning ball has been detected. Then, in step 520, it is determined whether or not the fraud detection signal S1 from the fraud detector 30b has fallen, and if it is determined that there has been a fall, it is assumed that the signal was turned ON due to a fraudulent act other than the winning ball. After the determination is made, the detector input process is ended and the process returns to the main routine without performing the following steps 330 to S90.

On the other hand, if it is determined that the fraud detection signal S1 does not fall, then in step S30 the starting prize openings 11a to llc
It is determined whether or not there is a falling of the winning ball signal S2 from the winning ball detectors 18a to 18c corresponding to the winning ball detectors 18a to 18c, and if there is a fall, the value of the winning ball counter C is set to "4" in step S40.
” It is determined whether the value is smaller than ”. If it is smaller than "4", the value of the winning ball counter is updated in step S50 (c=c+i). Also, if it is not smaller than "4",
That is, when the value of the winning ball counter C is "4", the winning ball counter C is not updated and the process advances to the next step S60. Also, when it is determined in step S30 that the winning ball signal S2 does not fall, the process proceeds to step S60.

In step S60, it is determined whether or not there is a falling of the big winning opening winning signal S3 from the adult winning opening winning detector 30a provided in the variable winning winning device 20, and if there is, in step S70 The value of the winning winnings counter G is updated (G=G+1), and the step S60
If it is determined that the adult prize opening winning signal S3 does not fall, the process proceeds to the next step S80.

In step S80, it is determined whether there is a fall of the winning ball signal S4 from the winning detector 30 provided in the variable winning device 20, and if there is a fall, the winning ball counter A is The value of is set to "1" (A=1). Further, if it is determined in step S80 that the V winning ball signal S4 does not fall,
Finish the detector input process and return to the main routine.

As explained above, the pachinko machine 1 in this embodiment
is equipped with a winning ball detector 3030a that detects winning balls, and a fraud detector 30b that operates on the same principle as the winning ball detector 30.30a at a position where winning balls do not pass. When the device 30b is ONL, the output of the winning ball detectors 30 and 30a is controlled not to be processed, so even if there is electromagnetic waves or magnetism generated intentionally or naturally from the outside, the game cannot be played. It has no effect on progress. In the flowchart shown in FIG. 5, the fall of the fraud detection signal S1 is determined first, but the falling of each winning ball signal S2, S3, and S4 is determined, and the falling of the fraud detection signal S1 is determined first. The fall of the fraud detection signal may be determined when the fraud detection signal is detected.

In addition, in the above-mentioned embodiment, a winning ball detector having a sensor section in which an electrical physical quantity changes is shown as a detector having a coil constituting an oscillation circuit, but a detector having a Hall element that detects the magnetic flux of a magnetic circuit is shown. A non-contact type detector such as a detector can be used in either case. In addition, although the variable winning device 20 is shown as a winning device equipped with a winning ball detector, it is not limited to this, and any winning device can be used as long as it is equipped with a detector that operates due to changes in electrical physical quantities. It may also be a winning device. For example, the starting prize opening 11
It may be a to Ilc.

In addition, as for the installation position of the fraud detector 30b, in the above embodiment, the one built in the variable prize winning device 20 was shown, but if it is near the winning device, it can be installed in the collecting gutter (of the game board) that guides the winning balls. It may also be provided on a mechanism board, a game board, etc., on which various devices for dispensing prize balls (fixed to the back surface) or various devices for dispensing prize balls are provided.

Furthermore, it is very easy to understand that depending on the performance of the device that generates electromagnetic waves, magnetism, etc., the same effect as the above embodiment can be achieved even if it is installed in any position of the pachinko machine 1.

[Effects of the Invention] As is clear from the above explanation, the pachinko machine according to the present invention has a sensor section that is provided in the winning device and whose electrical physical quantity changes according to the passage of accepted winning balls. A ball detector, a fraud detector installed in a position not related to the flow path of winning balls accepted into the winning device and having the same operating principle as the entered prize ball pressure detector, and when there is an output from the fraud detector. and detection output determination means for determining the output of the winning ball detector to be invalid.
When there is an output from the fraud detector, the output from the winning ball detector is presumed to have been fraudulently emitted by external electromagnetic waves or magnetism, and is determined to be invalid.

In other words, 1! that is intentionally or naturally generated! Even if the winning ball detector is activated by magnetic waves or magnetism, it is determined that the winning ball pressure detector has not been activated, so the game can proceed without any influence.
