Description

  The present invention relates to a gaming machine provided with a magnetic sensor.

  Conventionally, in gaming machines, for example, pachinko machines and pachislot machines, a predetermined game specification program is stored in an integrated circuit (including a microcomputer) mounted on a circuit board and is provided in the gaming machine. In addition, an image display unit such as an LCD, an electric decoration member such as an LED, and a movable member such as an electric accessory are controlled by the progress of the game based on the game specification program.

  A motor or a solenoid is applied to the electric accessory as a drive source for the operation. A motor or solenoid generates a magnetic force when driven. In particular, a solenoid is a mechanism that operates an actuator with an exciting force. For example, a pachinko machine can open and close an accessory device such as an electric tulip or a big prize opening (attacker) in a pachinko machine. The operation is applied to a drive source for the operation of the movable part for production. In addition, since a permanent magnet is applied to the motor and a magnetic force is generated by passing a current, the influence of the magnetic force is exerted on the surroundings.

  By the way, there is an illegal act of guiding a game ball with a magnetic force using a magnet or the like through the glass on the game board side. For example, during an attacker's opening / closing operation that is performed when a big hit is made, a game ball stays magnetically on the upper part of the attacker, wins the attacker at once, and wins illegally by winning far beyond the original winning ball limit number. There is a fraudulent act that receives a ball.

  For this reason, a magnetic sensor is attached to an appropriate part of the game board, and magnetic monitoring control is executed. In the magnetic monitoring control, when the magnetic force is detected by the magnetic sensor, the game specification program is interrupted or an alarm is sounded to take illegal measures. By this magnetic monitoring control, fraudulent acts due to magnetic force using a magnet or the like can be prevented in advance.

  On the other hand, a solenoid that operates an actuator with an exciting force is applied to the game board as a drive source of the electric accessory. It is contrary to the meaning of the magnetic monitoring control to detect the excitation operation of the solenoid and to execute the countermeasure against fraud.

  For this reason, it has been proposed to dispose the solenoid while avoiding the detection area (sensing range) of the magnetic sensor (see Patent Document 1).

JP 2009-066342 A

  However, as in Patent Document 1, each mounting position must be selected in consideration of the relative positional relationship between the magnetic sensor (that is, the detection region) and the solenoid, which greatly restricts the structure. Will receive.

  In particular, the detection area of the magnetic sensor may fluctuate with respect to the designed detection area of the single magnetic sensor in the initial stage of installation due to changes in the performance of the magnetic sensor over time or the positional relationship with surrounding metal parts. is there.

  When such a change occurs, it is impossible to change the mounting position of a magnetic sensor or solenoid that is already fixedly mounted, and the detection accuracy of the magnetic sensor must be lowered, which may hinder countermeasures against fraud. become.

  Further, as a factor that lowers the detection accuracy of the magnetic sensor, it is conceivable that the production of electric accessories accompanied by operations is diversified. In this electric accessory, when the solenoid for operating the electric accessory is installed on the back side of the game board, the solenoid may be forced to enter the detection range of the magnetic sensor due to the limitation of the installation space. .

  In consideration of the above-mentioned fact, the present invention detects occurrence of abnormality due to magnetic force generated from a drive unit such as an electric accessory operated by excitation control under magnetic monitoring control for detecting abnormality based on the detection result of the magnetic sensor. The object is to obtain a gaming machine that can be prevented.

The present invention uses a state of excitation or non-excitation by energization control to detect a magnetic force of a plurality of drive units that move a movable unit provided on a game board surface to at least two positions and a board surface of the game board. The magnetic force detection state is monitored by outputting an abnormal signal with respect to the magnetic force exceeding a predetermined strength, using a plurality of magnetic sensors provided in the sensor and a magnetic force detection signal from the magnetic sensor as an input source. In the monitoring means and the monitoring means, when the magnetic sensor detects a magnetic force exceeding a predetermined intensity, any of all the driving parts including the driving part outside the range where the magnetic sensor is affected by excitation. or is subjected determination means for determining whether or not being driven, the abnormality signal output from the pre-Symbol monitoring means, and a notifying means for notifying the occurrence of the abnormal force, control for executing the basic abnormality detection control means A first circuit group for energizing each of the plurality of drive units separately; a second circuit group for transmitting a detection signal detected by the magnetic sensor to input to a monitoring means; and the first circuit When any one of the groups is energized, the first circuit group and the second circuit are configured so as to invalidate the input of the detection signal from all of the second circuit group to the monitoring unit. And an electrical wiring circuit unit including a third circuit group for wiring the groups in association with each other .

According to the present invention , the drive unit moves the movable unit provided on the game board surface to at least two positions using the excited or non-excited state by the energization control.

  A plurality of magnetic sensors are provided to detect the magnetic force of the board surface of the game board. The monitoring means uses the magnetic force detection signal from the magnetic sensor as an input source and outputs an abnormal signal with respect to the magnetic force exceeding a predetermined strength, thereby monitoring the state of magnetic force generation.

  In the determination means, when the monitoring means detects a magnetic force exceeding a predetermined strength by the magnetic sensor, all the drive units including the drive units outside the range affected by the excitation by the energization control on the magnetic sensor are included. It is determined whether any of the drive units is being driven, and the abnormal signal canceling unit cancels the output of the abnormal signal when the determination unit determines that the drive unit is being driven.

For this reason, in this invention , it can prevent misdetecting a fraudulent act.

In the present invention , when there are a plurality of the drive units and the abnormal signal canceling unit determines that any one of the plurality of drive units is being driven, the abnormal signal output based on all the magnetic sensors is performed. It is characterized by cancellation.

  In order to prevent erroneous detection, it is not necessary to consider the relative positional relationship between the drive unit and the magnetic sensor.

In the present invention , a plurality of the drive units and a plurality of the magnetic sensors exist, and a pattern that affects the magnetic sensor is specified for each drive unit based on a relative positional relationship between the drive unit and the magnetic sensor. And based on the said pattern, the magnetic sensor which cancels the output of an abnormal signal by the drive of a drive part is selected.

  It is possible to reduce the frequency of canceling the output of an abnormal signal for preventing erroneous detection.

The first circuit group is provided with wiring for energizing the drive unit. The second circuit group is provided with wiring for transmitting the detection signal detected by the magnetic sensor in order to use it as the input source of the monitoring means.

Usually, the first circuit group and the second circuit group are not related and are provided independently. On the other hand, in the present invention , when any one of the first circuit groups is energized as the third circuit group , the sending function to the monitoring means is invalidated in all of the second circuit groups. As described above, the first circuit group and the second circuit group are wired in association with each other. For this reason, the detection signal of the magnetic sensor does not reach the input source during driving of the drive unit, and output of abnormal signals other than fraud can be avoided in advance.

  As described above, according to the present invention, it is possible to prevent the occurrence of abnormality detection due to the magnetic force generated from the drive unit operated by the excitation control under the magnetic monitoring control for detecting the abnormality based on the detection result of the magnetic sensor. Has an excellent effect.

(Game board configuration)
The game board 18 shown in FIG. 2 has a resin sheet-like cell attached to a plywood board serving as a substrate, and the surface of the cell is a board surface. An arc-shaped outer rail is provided near the outer peripheral edge of the board surface. 102 and the inner rail 104 are attached. A transparent acrylic plate or the like may be used instead of the veneer plate. In the circular area surrounded by the outer rail 102 and the inner rail 104, the game ball PB launched and driven from the launching device 165 (see FIG. 3) can be moved by its own weight fall, and this area is a game. This is a gaming area where

  In the game area of the game board 18, nails 19 (partial indices) are scattered and driven, and a windmill 21 is attached. In addition, a center accessory 105 is arranged almost in the center of the game area. The center accessory 105 includes movable accessory devices 105A and 105B that operate mechanically, and a display unit 106 that displays images such as various effects. Although detailed explanation is omitted, the movable accessory devices 105A and 105B are projected to the front of the display unit 106 as an operation for giving a player a sense of expectation of winning based on a result of a special symbol lottery described later. In addition, operation effects such as widening or narrowing the display surface of the display unit 106 are performed. On the other hand, LCD display, LED display, and the like can be applied to the display unit 106, but the display unit 106 is not particularly limited to the display form.

  In the display unit 106, for example, a symbol variation pattern effect for informing the result of the special symbol lottery is executed. As an example, if the symbol pattern of 3 columns is individually changed, and the symbol pattern when 2 of the symbol columns are stopped changing, the symbol becomes the same symbol. When the final row stops and becomes the same symbol as the already stopped two rows of symbols, the winning is notified, and when it becomes a different symbol, a loss is notified.

  A stage 105 </ b> S is formed at the lower side of the center accessory 105. A game ball PB received by rebounding with a nail or the like, or a game ball PB received guided by a warp path (not shown) is sent to the stage 105S.

  The stage 105S is formed with an inclined surface, a protrusion, etc., and the movement of the game ball PB changes irregularly by the inclined surface, the protrusion, etc., and finally returns to the game board 18 from the lower side. ing.

  As shown in FIG. 2, a special symbol start winning opening (A) 130 is arranged at the lower part of the center accessory 105. The special symbol start winning opening (A) 130 is open at the top so that it can always win.

  Further, at the lowest position of the game area of the game board 18, there is provided an out port 124 through which the dislodged ball is discharged to the back side of the game board 18.

  On the other hand, as shown in FIG. 2, a passing gate 118 having a normal symbol lottery starting function is arranged on the right side of the center accessory 105 in FIG.

  A special symbol start winning opening (B) 134 is disposed below the passing gate 118. The upper opening of the special symbol start winning opening (B) 134 is normally closed by the nail 19.

  An electric tulip 136 is attached to the special symbol start winning opening (B) 134. The electric tulip 136 is configured to open and close by energization / non-energization of an electric chew solenoid 138 (see FIG. 3) disposed on the back side of the game board 18.

  The electric tulip 136 is opened when the normal symbol lottery is won. When the electric tulip 136 is in the open state, the pachinko ball PB can be received in the winning opening of the special symbol start winning opening (B) 134, and the pachinko ball PB can be won.

  At the lower part of the special symbol start winning opening (B) 134, an attacker 112 dedicated to the jackpot for the special symbol lottery is arranged near the lower end of the game area.

  The attacker 112 is provided with an opening / closing door 116. The opening / closing door 116 is opened or closed by energization / non-energization of the attacker solenoid 148 (see FIG. 3). That is, when the open / close door 116 is opened, the game ball PB dropped on the open / close door 116 is guided by the open / close door 116 and wins the attacker 112.

  Here, when the game ball PB wins the special symbol start winning opening (A) 130 or the special symbol start winning opening (B) 134, the special symbol lottery is executed.

  In the special symbol lottery, when the “big hit” is won, the opening / closing door 116 of the attacker 112 is opened and closed in a predetermined pattern, and this is repeated a predetermined number of times (a predetermined round) (“special game”, “main character processing”). Etc.)).

  Note that the winning (“big hit”), which is the lottery result of the special symbol lottery, is mainly notified in the symbol variation display effect of the display unit 106, and in the case of the symbol variation display effect or during the major role processing, the lottery is performed. The notification of the result is on standby (holding / storing), and the notification is made sequentially. In addition to the symbol variation display effect, a character such as an anthropomorphic animal is displayed, and a visual effect is given to give the player a sense of expectation by implying that they have won the special symbol lottery. In this case, the player's interest is increased by sound effects.

  For example, while the normal time is a game in which the player hits the left side toward the center actor 105 (so-called “left-handed state”), the center actor 105 is directed toward the attacker 112 during the major player process. The game is changed to a game (so-called “right-handed state”) in which the player hits the right side of the game.

  In addition, when the game ball PB passes through the passing gate 118 in a specific gaming state (for example, “right-handed state” for a certain period after the big role processing), a normal symbol lottery is executed, and when the normal symbol lottery is won, The electric tulip 136 is opened. In the specific gaming state, since the electric tulip is opened for a long period of time, the probability of winning the special symbol start winning opening (B) 134 increases as compared to gaming states other than the specific gaming state.

  In the present embodiment, the specific game state is “short-time game state with electric tulip 136 support” (sometimes referred to as “short-time with electric support”, “short-time with electric support”, etc.), and with non-electric support. The time base is set to 20 while the time base with power support is set to 100. The base is the ratio of the number of prize balls paid out relative to the number of shot balls. For example, when 100 game balls PB are fired and there are 20 prize balls paid out, the base 20 is called. The time when there is a ball payout is called the base 100.

  The game board 18 has a plurality of general prize openings 120 (in the present embodiment) on the left side of the special symbol start winning opening (A) 130 (lower left of the game board 18) below the center role 105. The accessory device 107 provided with the two general winning openings 120A and 120B) is disposed. The number of the general winning openings 120 is not limited to two. For example, the number may be determined by a design calculation such as a basic base and a winning rate.

  In the present embodiment, a maximum of four per special symbol start winning opening (in this embodiment, two of special symbol start winning opening (A) 130 and special symbol start winning opening (B) 134 are shown. Since it is a special symbol start winning slot, the number is 8). Reservation (memory for starting winning of game ball) is possible. The number of reserved balls is not limited.

  The number of reserved balls is mainly determined by a special symbol memory display unit which is a part of the game progress guide lamp unit 109 having a special symbol display unit (located at the lower right when the center accessory 105 shown in FIG. 2 is viewed from the front). Informed.

  In addition, an electrical decoration device 122 is disposed on the surface of the game board 18 between the center accessory 105 and the accessory device 107 so as to be embedded on the back side of the surface. It can be seen that there is a portion into which the nail 19 is driven on the front surface of the electric decoration device 122, and it is on a flow path through which the game ball PB can pass. For this reason, the player can visually recognize the effect state of the electrical decoration device 122 without shifting the line of sight of the trend of the game ball PB.

(Anti-fraud measures)
In the pachinko machine 10 according to the present embodiment, a fraudulent act that attempts to change the trend of the game ball PB by shaking or hitting the pachinko machine 10, and a glass plate 14 having a magnet in the hand (FIG. 1). As a countermeasure against fraud that attempts to change the trend of the game ball PB by moving it closer to (see), the back side of the game board 18 has a vibration sensor 200 and a plurality of (three in this embodiment). ) Magnetic sensors 202A, 202B, 202C are provided.

  The vibration sensor 200 is provided at an upper left corner (that is, an upper right corner on the back side) with respect to the front of the game board 18 shown in FIG. 2 (see a rectangular frame).

  The position of the vibration sensor 200 is not particularly limited, and may be attached to a position where vibration is most easily transmitted with respect to the entire game board 18. In the present embodiment, the vibration of the entire area of the game board 18 is detected by one vibration sensor 200, but a plurality of vibration sensors 200 may be arranged.

  On the other hand, the magnetic sensor 202A is located at the upper left of the special symbol start winning opening (A) 130 (that is, the upper right of the special symbol starting winning opening (A) 130 on the back side) with respect to the front of the game board 18 shown in FIG. To be arranged).

  The magnetic sensor 202B is arranged above the special symbol start winning opening (B) 134 and in the vicinity of the arrangement position of the passing gate 118 with respect to the front of the game board 18 shown in FIG.

  The magnetic sensors 202C are disposed at the lower right of the attacker 112 (that is, the lower left of the attacker 112 on the back side).

  In FIG. 2, the three magnetic sensors 202A, 202B, and 202C are indicated by a rectangular frame, and the magnetic force detection range Amag is indicated by a circular dotted line frame. Although details will be described later, the magnetic force detection range Amag is actually a three-dimensional space like a sphere.

  Here, within the magnetic force detection range Amag of each of the magnetic sensors 202A, 202B, and 202C, as described above, the special symbol start winning port (A) 130, the special symbol start winning port (B) 134, the attacker 112 exists. These common points are the accessory device provided with a winning opening. In addition, there is a case of an electric accessory that moves a movable member (such as the electric tulip 134 and the opening / closing member 116) by a magnetic force.

  In the case of this electric accessory, for example, when the opening / closing door 116 of the attacker 112 is open, there is an illegal act such as bringing the magnet close to the hand, causing the game balls PB to concentrate and stay and win at once. The magnetic sensor 202C outputs a detection signal having a strength for notifying abnormality.

  Or, conversely, aiming at the time when the opening / closing door 116 of the attacker 112 is closed, the game ball PB is stored in advance above the avoidance door 116 with a magnetic force, and the magnetic force is released after the opening / closing door 116 is opened, If there is a fraudulent act that wins at once, the magnetic sensor 202C outputs a detection signal having a strength for notifying abnormality.

  The main control unit 150, which will be described later, is provided with a fraud monitoring control unit 204 (see FIG. 3), which receives detection signals from the magnetic sensors 202A, 202B, 202C as input sources, and sets a predetermined threshold value. In comparison, when the detection signal exceeds the threshold value, an abnormal signal is output to monitor the fraud (details will be described later). The fraud monitoring control unit 204 receives a detection signal from the vibration sensor 200 and also performs fraud monitoring regarding vibration.

  On the other hand, when operating a movable member using a magnetic force in an accessory device, particularly an electric accessory, the magnetic sensors 202A, 202B, and 202C, each of which is in the magnetic force detection range Amag, output a detection signal having a strength for notifying abnormality. There is.

  For example, in the attacker 112, while the door 116 is open, the attacker solenoid 148 (see FIGS. 4 and 5) is excited, and the magnetic force due to this excitation may be detected by the magnetic sensor 202C.

  In the special symbol start winning opening (B) 134, while the electric tulip 136 is open, the electric chew solenoid 138 (see FIGS. 4 and 5) is excited, and the magnetic force due to this excitation is detected by the magnetic sensor 202B. May be.

  In order to avoid this, the attacker solenoid 148 and the electric Chu solenoid 138 may be arranged at a position deviating from the magnetic force detection range Amag. However, the structural restrictions are great, and the degree of freedom of the arrangement of the objects on the game board 18 is lost. It will be.

  Therefore, in the present embodiment, there is no need to consider the relative positional relationship between the drive source that generates the magnetic force of the electric utility and the magnetic force detection area Amag of the magnetic sensors 202A, 202B, and 202C, and the operation of the drive source The fraud monitoring control unit 204 that avoids the erroneous output of the abnormal signal due to is constructed.

  Hereinafter, based on FIGS. 4 and 5, the detailed structure of the attacker 112 located in the magnetic force detection range Amag of the magnetic sensor 202 </ b> C will be described as an example of the electric accessory.

  FIG. 4A is a front view of the attacker electric accessory 206 as seen from the front of the game board 18, and the decorative member 208 made of synthetic resin constituting the entire appearance is a part of a circular game area. It is formed in an arc shape along the lower right arc.

  The decorative member 208 is formed with a horizontally long rectangular (rectangular) opening 210 (see FIG. 4B). The opening 210 is one of the winning holes for the game ball PB falling on the game board 18 and receives a winning ball when winning.

  The lower side of the opening 210 is connected to the lower side of the opening / closing door 116 via a hinge (not shown). Therefore, the opening / closing door 116 functions as a receiving member that closes the opening 210 around the lower side, and opens the opening 210 and guides the falling game ball PB to the opening 210.

  As shown in FIG. 5, on the back side of the opening 210, a bracket 212 is provided that guides the winning game ball PB and supports an attacker solenoid 148 that performs the opening / closing operation of the opening / closing door 116. The attacker solenoid 148 is provided with an actuator 148A (see FIG. 4A) that expands and contracts by excitation / non-excitation, and the actuator 148A and the opening / closing door 116 are connected via a link mechanism (not shown).

  For this reason, the opening / closing door 116 is opened / closed by excitation / de-energization of the attacker solenoid 112.

  A magnetic sensor 202C is attached to the bracket 212 so that the detection surface faces the back surface of the game board 18. The detection range Amag of the magnetic sensor 202C is circular when viewed from the front of the game board 18, as shown in FIG. However, actually, as shown in FIG. 4B, a substantially spherical detection range Amag is formed before and after the detection surface of the magnetic sensor 202C.

  The detection range Amag sufficiently secures an area on the front surface of the game board 18 where an illegal act may be executed. On the other hand, the detection range Amag includes the attachment area of the attacker solenoid 148. For this reason, when the attacker solenoid 148 is excited, the magnetic sensor 202C outputs a detection signal having an intensity exceeding the threshold value.

Although not shown, the electric chew solenoid 138 that operates the electric tulip 136 that is a movable part and the magnetic sensor 202B are also close to each other in the special symbol start winning opening (B) 134. Is located within the magnetic detection range Amag of the magnetic sensor 202B.

And are connected. The main control unit 150 stores a basic program relating to games, and the operation of each unit is controlled based on a command signal from the main control unit 150.

  Information indicating the progress of the game (start winning signal, jackpot signal, symbol determination number signal, etc.) is transmitted from the main control unit 150 to the hall computer (not shown) via the board external terminal 190.

  The main control unit 150 includes, as an input system, a pass gate sensor 118S that detects a game ball PB passing through the pass gate 118, and a special figure A start port sensor that detects a winning ball to the special symbol start winning port (A) 130. 130S, special figure B start opening sensor 134S for detecting a winning ball to the special symbol starting winning opening (B) 134, an attacker sensor 112S for detecting a winning ball to the attacker 112 that is released in the case of "big hit", a general winning opening General winning sensors 120AS and 120BS for detecting winning balls to 120A and 120B are connected.

  In addition, the main control unit 150 has an output system that opens and closes a guide lamp unit 109 for notifying game information and a game state by lighting a lamp, an electric chew solenoid 138 for opening and closing the electric tulip 136, and an opening and closing door 116 for the attacker 112.

(Function of fraud monitoring control unit 204)
FIG. 6 is a functional block diagram for fraud monitoring control for the magnetic sensors 202A, 202B, and 202C in the fraud monitoring control unit 204 and the magnetic detection signal management circuit 205.

  Although not shown in the vibration sensor 200, the player or the like intentionally and illegally sets the game board 18 using the vibration state (intensity (amplitude), unit vibration frequency (frequency), vibration period, etc.) as parameters. It is only necessary to monitor whether or not an action such as shaking or hitting is being performed.

  As shown in FIG. 6, the magnetic sensors 202 </ b> A, 202 </ b> B, and 202 </ b> C are connected to the detection signal receiving unit 214 via the magnetic detection signal management circuit unit 205. The detection signal receiving unit 214 receives a detection signal corresponding to the magnetic intensity detected by the magnetic sensors 202A, 202B, and 202C.

  The circuit configuration of the magnetic detection signal management circuit unit 205 will be described later. As an input system, in addition to the magnetic sensors 202A, 202B, and 202C, the operation signal of the electric accessory (in this case, the operation signal of the attacker solenoid 148 and the electric chew solenoid) 138 operation signal) is input. On the other hand, as an output system of the magnetic detection signal management circuit unit 205, power lines 148P and 138P for driving the attacker solenoid 148 and the electric chew solenoid 138 are connected.

  As an outline, in the magnetic detection signal management circuit unit 205, the abnormal level magnetic detection signal (based on the magnetic force by the magnetic sensors 202A, 202B, and 202C) while the electric combination including the attacker solenoid 148 and the electric chew solenoid 138 is not operating. The H signal) or the magnetic non-detection signal (L signal) is sent to the detection signal receiving unit 214 as an input source. On the other hand, in the magnetic detection signal management circuit unit 205, while the electric combination including the attacker solenoid 148 and the electric chew solenoid 138 is operating, even if an abnormal level of magnetic force is generated, the magnetic non-detection signal (L signal) ) Is sent to the detection signal receiving unit 214.

  The detection signal reception unit 214 is connected to the signal determination unit 215. In the present embodiment, the magnetic sensor 202C itself outputs digital information (binary signal “H / L signal”) when it receives an abnormal magnetic force and when it does not (see FIG. 7), the signal determination unit 215 determines whether the detection signal is an H signal or an L signal.

  The determination result in the signal determination unit 215 is sent to the abnormal signal output unit 222.

  In the present embodiment, the output signal of the magnetic sensor 202C is digital information (binary signal “H / L signal”), but the magnetic detection signal is analog information (for example, voltage value), and the intensity thereof is You may make it determine whether it is abnormal compared with a threshold value.

  The abnormal signal output unit 222 is connected to the panel external terminal 190 and the notification device 226 (the display unit 106, the light source 137, the speaker 60, and the like), and outputs a signal for reporting the abnormality to each. For example, an abnormal signal decodable by the host computer is output to the board external terminal 190. Further, an abnormal signal based on image expression is output to the display unit 106. An abnormal signal based on lighting expression is output to the light source 137. An abnormal signal by voice expression is output to the speaker 60. The output destination of the abnormal signal may be one, or two or more may be used together.

FIG. 7 is a circuit diagram showing a detailed circuit configuration of the magnetic detection signal management circuit unit 205.

  The magnetic detection signal management circuit unit 205 sends a detection signal related to magnetism from the first circuit energizing the attacker solenoid 148 and the electric chew solenoid 138 and the magnetic detection sensors 202A, 202B, 202C to the fraud monitoring control unit 204. The second circuit is provided.

  Since the basic circuit configurations of the magnetic detection sensors 202A, 202B, and 202C are the same and are connected in parallel to each other, the circuit configuration of the magnetic detection sensors 202A, 202B, and 202C will be described below using the same reference numerals. To do.

  The magnetic detection sensors 202A, 202B, and 202C include an NPN transistor 230 (hereinafter referred to as “TR230”), and the base (B) emits an L signal when receiving a magnetic force, and does not receive the magnetic force. DC power is supplied so as to generate an H signal. Further, a DC power supply line 234 is connected to the collector (C) of the TR 230 via a resistor 232, and the emitter (E) is grounded via a ground line (earth line) 236.

  The collector of TR 230 is connected to the fraud monitoring control unit 204 via a diode 235 and a signal line 237. The signal line 237 belongs to the second circuit together with the DC power line 234 and the resistor 232.

  In TR 230, when the base is not receiving magnetic force (H signal), the collector-emitter is turned on, and a current flows between the collector and emitter of TR 230 from the DC power source via resistor 232. For this reason, the L signal is sent to the fraud monitoring control unit 204. This L signal means that no magnetism has been detected.

  In TR230, when the base receives a magnetic force (L signal), the collector-emitter is turned off, and a current flows from the DC power source to the fraud monitoring control unit 204 via the resistor 232 and the signal line 237. For this reason, an H signal is sent to the fraud monitoring control unit 204. This means magnetic detection.

  On the other hand, the magnetic detection circuit management circuit unit 205 is provided with a circuit (first circuit) for driving and controlling the attacker solenoid 148 and the electric chew solenoid 138.

  In the first circuit, an operation signal (attacker open / close signal) for opening and closing the door 116 of the attacker 112 is supplied to the gate (G) of the N-channel junction FET 238AS (hereinafter referred to as “FET 238AS”) by the operation signal line 239AS. Have been entered. The source (S) of the FET 238AS is grounded, and the cathode side is connected to the negative terminal of the attacker solenoid 148. The FET 238AS belongs to the first circuit.

  In the first circuit, an operation signal (electric Chu open / close signal) for opening and closing the electric tulip 136 is supplied to the gate (G) of the N-channel junction FET 238DS (hereinafter referred to as “FET 238DS”) by the operation signal line 239DS. Have been entered. The source (S) of the FET 238DS is grounded, and the cathode side is connected to the minus side terminal of the attacker solenoid 148. The FET 238DS belongs to the first circuit.

A DC power source is connected to the positive side terminals of the attacker solenoid 148 and the electric Chu solenoid 138 via a power line 234, respectively.

  In the first circuit configured as described above, when an operation signal is input to the gate of the FET 238AS, the drain-source is turned on, the DC power supply energizes the attacker solenoid 148, and the door 116 is opened.

  When an operation signal is input to the gate of the FET 238DS, the drain-source connection is turned on, the DC power supply energizes the electric chew solenoid 138, and the electric tulip 136 is opened.

  Here, the signal line 237 between the resistor 232 and the fraud monitoring controller 204 in the second circuit is connected to the anode side of the diode 240AS, and the cathode side of the diode 240AS is connected to the drain (D) of the FET 238AS. ing. The diode 240AS and the detour line 241AS before and after the diode 240AS belong to a third circuit for linking the first circuit and the second circuit.

  In the second circuit, the signal line 237 between the resistor 232 and the fraud monitoring control unit 204 is connected to the anode side of the diode 240DS, and the cathode side of the diode 240DS is connected to the drain (D) of the FET 238DS. Yes. The diode 240DS and the detour lines 241DS before and after the diode 240DS belong to a third circuit for linking the first circuit and the second circuit.

  Accordingly, when the FET 238AS is on, a signal (mainly H signal) flowing through the signal line 237 flows to the FET 238AS via the diode 240AS. In other words, the H signal is not sent to the fraud monitoring control unit 204. When the FET 238DS is on, a signal (mainly H signal) flowing through the signal line 237 flows to the FET 238DS through the diode 240DS. In other words, the H signal is not sent to the fraud monitoring control unit 204.

  That is, when the first circuit and the second circuit are linked and the attacker solenoid 148 is on (opening of the door 116) or the electric chew solenoid 138 is on (opening of the electric tulip 136), the magnetic sensor 202A, The detection signals 202B and 202C are bypassed to the FET 238AS or FET 238DS and canceled.

  The operation of this embodiment will be described below.

  In the game using the pachinko machine 10, when the player operates the grip unit 26, the ball is shot upward by the launching device 165 one by one. The launched game ball PB is driven into the substantially circular game area of the game board 18 along the outer rail 102 and falls in the game area while changing the direction by hitting the game nail or the windmill. Then, the game ball PB reaching the lower end of the game area without winning a prize is collected into the pachinko machine 10 from the out port 124.

(Game specifications according to this embodiment)
In the present embodiment, the so-called “left-handed” game is the basic (basic game). That is, the special symbol start winning opening (A) is adjusted while abutting against an obstacle such as a windmill or a nail by adjusting the firing strength of the game ball PB so as to pass through the left side of the game board 18 with the display unit 106 as a boundary. The game ball is guided to 130, and when winning, a special symbol lottery is executed.

  In the special symbol lottery, the player is notified of the lottery result by the symbol variation pattern effect executed on the display unit 106. The symbol variation pattern effect is executed by selecting a symbol variation pattern type from the symbol variation pattern selection table based on an instruction signal from the main control unit 150 or the like.

  When the special symbol lottery is won, the open / close door 116 of the attacker 112 is opened for a predetermined time and a predetermined number of times, and a big game process is executed to dramatically increase the winning of the game ball from the normal gaming state.

  Apart from the basic game, the big game process is a so-called “right-handed” game.

  That is, by adjusting the firing strength of the game ball PB so that it passes through the right side of the game board 18 with the display unit 106 as a boundary, the game ball is guided to the attacker 112 while contacting an obstacle such as a windmill or a nail. Go.

  Next, when the big character process is completed, there are a case where the left-handing is returned and a case where the right-handing is continued. When the right hand is continued, the game ball is guided to the special symbol start winning opening (B) 134. At this time, it is in a short-time state, and when the game ball PB passes the passing gate 118, the normal symbol lottery is executed in the short-time state, and if the winning (for example, the winning probability 1 / 1.1) is achieved, the electric tulip 136 is frequently The special symbol start winning opening (B) 134 can be won. When the game ball PB wins the special symbol start winning opening (B) 134, the special symbol lottery is executed in the same manner as the special symbol start winning opening (A) 130.

  Here, the program for executing the game specifications is stored in a storage unit (for example, ROM) of the main control unit 150, and the program is executed. Further, the main control unit 150 executes the operation of the electric chew solenoid 138, the operation of the attacker solenoid 148, and the lighting control of the guide lamp unit.

  Further, the effect control unit 152 includes display control of the display unit 106 through the symbol control unit 156, and an effect through hearing and vision is executed. The payout control unit 154 executes payout control of the game ball PB.

  Hereinafter, the fraud monitoring control routine by the magnetic sensors 202A, 202B, and 202C according to the present embodiment will be described with reference to the flowchart of FIG.

  In step 250, detection signals from the magnetic sensors 202A, 202B, and 202C are captured. In the next step 252, it is determined whether the type of the detection signal is an H signal that is an abnormal signal or an L signal that is a normal (non-abnormal) signal.

  In the next step 254, it is determined whether or not the detection signal is an H signal. If the determination is negative, it is determined that there is no fraud, and this routine ends.

  On the other hand, if an affirmative determination is made in step 254, it is determined that there is a possibility of fraud, and the routine proceeds to step 258 to output an abnormal signal, and this routine ends.

  Here, in this embodiment, the fraud monitoring control unit 204 detects the fraud in the magnetic detection signal management circuit unit 205 before determining whether there is fraud based on the detection signal received by the detection signal reception unit 214. The detection signal received by the signal receiving unit 214 is managed.

  That is, even when an electric role such as the attacker solenoid 148 or the electric chew solenoid 138 is excited, the magnetic sensors 202A, 202B, 202C detect the magnetism corresponding to the abnormality, so that an abnormality signal (H signal) is output. It will be.

  For this reason, in the magnetic detection signal management circuit unit 205, the detection signal is prevented from being sent to the detection signal reception unit 214 while the electric appliances such as the attacker solenoid 148 and the electric tuner solenoid 138 are energized. .

  Based on FIG. 7, the flow of the detection signal when the energizer solenoid 148 is not energized and energized will be described.

(Magnetic sensor 202A)
The operation of the magnetic sensor 202A will be described.

  When the magnetic sensor 202A does not detect a predetermined magnetism, an H signal is input to the base of the TR 230, the collector-emitter of the TR 230 is turned on, and the route of the power line 234-resistance 232-TR230-ground is conducted. As a result, a current flows and an L signal (normal detection signal) is sent to the detection signal receiving unit 214.

  On the other hand, when a predetermined magnetism is detected by the magnetic sensor 202A, an L signal is input to the base of the TR 230, the collector-emitter of the TR 230 is turned off, and the route of the power line 234-resistance 232-TR230-ground is not present. An electric current does not flow due to the conduction state, and an H signal (abnormal detection signal “abnormal signal”) is sent to the detection signal receiving unit 214.

(Magnetic sensor 202B)
The operation of the magnetic sensor 202B will be described.

  When the magnetic sensor 202B does not detect a predetermined magnetism, an H signal is input to the base of the TR 230, the collector-emitter of the TR 230 is turned on, and the route of the power supply line 234-resistance 232-TR230-ground is conducted. As a result, a current flows and an L signal (normal detection signal) is sent to the detection signal receiving unit 214.

  On the other hand, when a predetermined magnetism is detected by the magnetic sensor 202B, an L signal is input to the base of TR230, the collector-emitter of TR230 is turned off, and the route of power line 234-resistance 232-TR230-ground is not An electric current does not flow due to the conduction state, and an H signal (abnormal detection signal “abnormal signal”) is sent to the detection signal receiving unit 214.

(Magnetic sensor 202C)
The operation of the magnetic sensor 202C will be described.

  When the magnetic sensor 202C does not detect a predetermined magnetism, an H signal is input to the base of the TR 230, the collector-emitter of the TR 230 is turned on, and the route of the power line 234-resistor 232-TR230-ground is conducted. As a result, a current flows and an L signal (normal detection signal) is sent to the detection signal receiving unit 214.

  On the other hand, when a predetermined magnetism is detected by the magnetic sensor 202C, an L signal is input to the base of the TR 230, the collector-emitter of the TR 230 is turned off, and the route of the power line 234-resistor 232-TR230-ground is not present. An electric current does not flow due to the conduction state, and an H signal (abnormal detection signal “abnormal signal”) is sent to the detection signal receiving unit 214.

  That is, the magnetic sensor 202A, 202B, 202C performs the same operation independently.

(Handling of abnormal signal based on operation of attacker solenoid 148)
Next, handling of the abnormal signal according to the state of the attacker solenoid 148 will be described.

  When the attacker solenoid 148 is not energized, that is, when the operation signal is an L signal, since the L signal is input to the gate of the FET 238AS, the drain-source is turned off. As a result, the route of the power supply line 234-resistor 232-diode 240 AS-FET 240 AS-ground becomes non-conductive.

  Therefore, the detection signals sent from the magnetic sensors 202A, 202B, and 202C can reach the detection signal receiving unit 214 via the signal line 237.

  On the other hand, when the attacker solenoid 148 is energized, that is, when the operation signal is an H signal, since the H signal is input to the gate of the FET 238AS, the drain-source is turned on. As a result, the route of the power supply line 234-resistor 232-diode 240 AS-FET 240 AS-ground becomes conductive.

  For this reason, the detection signal sent from the magnetic sensor 202C is guided as signal line 237-diode 240AS-FET 238AS, does not reach the detection signal receiving unit 214, and is always equivalent to normal to the detection signal receiving unit 214. A signal (L signal) is transmitted.

(Handling of abnormal signal based on operation of electric chew solenoid 138)
On the other hand, handling of an abnormal signal according to the state of the electric chew solenoid 138 will be described.

  When the electric chew solenoid 138 is not energized, that is, when the operation signal is an L signal, since the L signal is input to the gate of the FET 238DS, the drain-source is turned off. As a result, the route of the power supply line 234-resistor 232-diode 240DS-FET240DS-ground becomes non-conductive.

  Therefore, the detection signals sent from the magnetic sensors 202A, 202B, and 202C can reach the detection signal receiving unit 214 via the signal line 237.

  On the other hand, when the electric chew solenoid 138 is energized, that is, when the operation signal is an H signal, the H signal is input to the gate of the FET 238DS, so that the drain-source is turned on. As a result, the route of the power supply line 234-resistor 232-diode 240DS-FET240DS-ground becomes conductive.

  For this reason, the detection signal sent from the magnetic sensor 202C is guided as the signal line 237-diode 240DS-FET 238DS, does not reach the detection signal reception unit 214, and is always equivalent to normal to the detection signal reception unit 214. A signal (L signal) is transmitted.

According to the present embodiment, even if the magnetic force generated by the operation of the attacker solenoid 148 or the electric chew solenoid 138 is detected by the magnetic sensors 202A, 202B, 202C, the magnetic force disposed upstream of the fraud monitoring control unit 204. In the detection signal management circuit unit 205, the detection signal flow is bypassed based on the cooperation between the first circuit and the second circuit, so that it is not determined to be abnormal. Mouth (B) 134, etc.) and the magnetic sensors 202A, 202B, 202C can be arranged without considering the relative positional relationship, and the degree of design freedom can be increased.

  In the embodiment, the attacker 112 and the special symbol start winning opening (B) 134 are cited as the electric accessory, and when either the attacker solenoid 148 or the electric chew solenoid 138 as the driving source is driven, Although the abnormal-level magnetic force detection (H signal) from all the magnetic sensors 202A, 202B, 202C is prohibited (cancelled) from being sent to the fraud monitoring control unit 204, a drive source using other magnetic force For example, even when the driving source for operating the movable accessory devices 105A and 105B shown in FIG. 2 is driven, abnormal magnetic force detection (H signal) from all the magnetic sensors 202A, 202B and 202C is incorrect. Transmission to the monitoring control unit 204 may be prohibited (cancelled).

  Furthermore, when the arrow-shaped accessory device provided so as to partially overlap the movable accessory device 105B on the right side of FIG. 2 is a movable part, when the drive source of the arrow-shaped accessory device is driven In this case, the abnormal level magnetic force detection (H signal) from all the magnetic sensors 202A, 202B, 202C may be prohibited (cancelled) from being sent to the fraud monitoring control unit 204.

(Modification)
Moreover, in the said embodiment, when any of all the drive parts (quantity N) is driving, the structure which interrupts | blocks the detection capability of all the magnetic sensors (quantity S) (N: S = plurality: plurality) However, the ratio of the quantity of the drive unit N and the magnetic sensor S may be grouped as N: S = 1: 1, N: S = 1: multiple, N: S multiple: 1. .

  Furthermore, it is not limited to one group, but may be grouped so as to straddle a plurality of groups.

For example, as shown in FIG. 9, when there are sensors A, B, C, D and a driving source (herein referred to as “solenoid”) 1, 2, 3, 4 using magnetic force, the following pattern Is assumed.
(Pattern 1) The driving state of the solenoid 1 affects the sensor A.
(Pattern 2) The driving state of the solenoid 2 affects the sensors A, B, C, and D.
(Pattern 3) The driving state of the solenoid 3 affects the sensors A and C.
(Pattern 4) The driving state of the solenoid 4 affects the sensors A, C, and D.

  By grouping in consideration of the above pattern, the accuracy of fraud monitoring can be improved and the accuracy of preventing false detection can be increased. Note that the pattern assumption is not limited to FIG. 9, but may be set according to the component arrangement of the game board 18 and the sensors may be grouped based on the set assumption pattern.
