Abstract

PROBLEM TO BE SOLVED: To prevent abnormality detection caused by a magnetic force generated by an electric accessory operated by excitation control from occurring under magnetism monitor control in which abnormality is detected on the basis of a result of detection by a magnetic sensor.SOLUTION: In an attacker 112, since an attacker solenoid 148 is excited while an opening/closing door 116 opens, a magnetic force generated by the excitation is sometimes detected by a magnetic sensor 202C. To prevent the detection, the attacker solenoid 148 should be arranged at a position that is out of a magnetic force detection range Amag thereof; however, a degree of freedom in arranging an accessory in a game board 18 is lost due to severe restrictions on structure. Thus, a fraud monitor control unit 204 is configured to prevent an incorrect output of a signal for abnormality caused by an operation of a driving source without necessity to consider a relative positional relation between the driving source generating a magnetic force of an electric accessory and the magnetic force detection range Amag of the magnetic sensor 202C.

Description

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

  Conventionally, in gaming machines, such as pachinko machines and pachislot machines, a game specification program predetermined in an integrated circuit (including a microcomputer) mounted on a circuit board is stored and provided in the gaming machine. 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, and can be moved between two positions with a short stroke. For a pachinko machine, a drive for opening and closing an electric tulip or a grand prize opening (attacker) Applied to the source. 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).

As a result, it is possible to prevent an illegal act of guiding the game ball using magnetic force. However, when the drive unit is driven and excited, a magnetic force exceeding a predetermined strength may be generated. Therefore, according to the present invention, when the drive unit is in the excited state, the prohibition means The monitoring by the magnetic force detection from the magnetic sensor by the monitoring means is prohibited.

  Further, according to the present invention, the board surface of the game board has an opening for receiving a game ball, and the magnetic sensor is arranged so that the vicinity of the opening of the opening is a detection range.

  According to the present invention, the magnetic sensor can prevent an illegal act such as guiding a game ball using a magnetic force in the vicinity of the opening of the opening portion.

  Furthermore, the present invention has a notifying means for receiving an abnormal signal output from the monitoring means and notifying the occurrence of an abnormal magnetic force.

  With this configuration, the present invention promptly notifies the occurrence of an abnormal magnetic force, thereby more reliably preventing an illegal act that induces a game ball using the magnetic force.

  In addition, the present invention further includes storage means for storing abnormal signal occurrence history information, wherein the storage means stores abnormal signal occurrence history information, including the excitation state of the drive unit. Yes.

(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 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.

  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 the movable member is operated using magnetic force in the accessory device, particularly the electric accessory, the magnetic sensors 202B and 202C, each of which is in the magnetic force detection range Amag, may output a detection signal having a strength for notifying abnormality. .

  For example, in the attacker 112 as well, 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 order to avoid this, the attacker solenoid 148 may be disposed at a position deviating from the magnetic force detection range Amag. However, the structural restriction is great, and the degree of freedom of the arrangement of the objects on the game board 18 is lost.

  Therefore, in the present embodiment, it is necessary to consider the relative positional relationship between the drive source that generates the magnetic force of the electric power article and the magnetic force detection area Amag of the magnetic sensor (magnetic sensors 202B and 202C in the present embodiment). And the fraud monitoring control unit 204 that avoids erroneous output of an abnormal signal due to the operation of the drive source was 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.

FIG. 6 is a functional block diagram for fraud monitoring control for the surroundings of the magnetic sensor 202C, that is, the attacker 112, in the fraud monitoring control unit 204. It should be noted that fraud monitoring control is possible with the same function in the other magnetic sensors 202A and 202B.

  Further, in the vibration sensor 200, although not shown, the player or the like intentionally and improperly uses the game board 18 with the vibration state (intensity (amplitude), number of unit vibrations (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 sensor 202 </ b> C is connected to the detection signal receiving unit 214. The detection signal receiving unit 214 receives a detection signal corresponding to the intensity of magnetism detected by the magnetic sensor 202C.

  The detection signal reception unit 214 is connected to the signal strength comparison unit 216. In addition, a signal strength threshold value storage unit 218 is connected to the signal strength comparison unit 216. Therefore, the signal intensity comparison unit 216 receives the detection signal from the magnetic sensor 202C and the threshold value and compares them.

  The comparison result in the signal intensity comparison unit 216 is sent to the magnetic abnormality presence / absence determination unit 220. In the case of the detection signal exceeding the threshold value, the magnetic abnormality presence / absence determination unit 220 determines that it is “abnormal”, and outputs an abnormal signal to the abnormality signal output unit 222 if it is determined as “abnormal”. Send an instruction signal.

  The abnormality signal presence / absence determination unit 220 is connected to the abnormality history information storage unit 224 so as to store a magnetic abnormality occurrence history.

  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.

  Here, the fraud monitoring control unit 204 is provided with a drive source operation monitoring unit 228, and from the game control system of the main control unit 150, a game state (operation driving using magnetism such as the attacker solenoid 148 and the electric tulip 134). Source operation information).

  The drive source operation monitoring unit 228 is connected to the magnetic monitoring operation execution availability determination unit 230. The magnetic monitoring operation item availability determination unit 230 determines whether to perform monitoring by the magnetic sensor 202C based on the driving state of the attacker solenoid 148. This determination result is sent to the abnormal signal output cancel unit 232. The abnormal signal output cancel unit 232 is connected to the abnormal signal output unit 222 and manages whether or not to output an abnormal signal.

  That is, in this embodiment, when the attacker solenoid 148 is excited, the output of the abnormal signal is canceled even if the abnormality is determined by the detection signal from the magnetic sensor 202C.

  The excitation of the attacker solenoid 148 is one of the two positions of the open / close door 116, for example, usually when the open / close door 116 is open, but even when the open / close door 116 is closed. Good.

  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. 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 sensor 202C according to the present embodiment will be described according to the flowchart of FIG.

  In step 250, a detection signal from the magnetic sensor 202C is captured. In the next step 252, the threshold value is read out, and then the process proceeds to step 254 to compare the signal strength of the detection signal with the threshold value.

  In the next step 256, it is determined whether or not the signal strength of the detection signal exceeds the threshold value as a result of the comparison in step 254. If the determination is negative, it is determined that there is no fraud, and this routine is performed. Ends.

  On the other hand, if an affirmative determination is made in step 256, it is determined that there is a possibility of fraud, and the process proceeds to step 258 to update the abnormality determination history information, and then the process proceeds to step 260 and the attacker as the driving source. It is determined whether the solenoid 148 is operating.

  If a negative determination is made in step 260, it is determined that the abnormality determination in step 256 is due to an illegal act, the process proceeds to step 262, an abnormality signal is output, and this routine ends. If the determination at step 260 is affirmative, it is determined that the abnormality determination at step 256 is due to the operation of the attacker solenoid 148, and the routine proceeds to step 264 to cancel the output of the abnormality signal. Ends.

  According to the present embodiment, even if the magnetic force generated by the operation of the attacker solenoid 148 is detected by the magnetic sensor 202C, it is not determined to be abnormal. Therefore, the relative positional relationship between the attacker 112 and the magnetic sensor 202C is taken into consideration. Therefore, the degree of freedom in design can be increased.

  Further, in the present embodiment, the abnormality detection by the magnetic sensor 202C is continued, and the true abnormality and the abnormality due to the operation of the attacker solenoid 148 can be left as histories, so the relative positional relationship between the attacker 112 and the magnetic sensor 202C. Further, it can be used as information for subsequent designs such as the orientation of the detection surface of the magnetic sensor 202C.

(Modification)
Hereinafter, modifications of the fraud monitoring control unit 204A according to the present embodiment will be described.

  In addition, in a modification, about the same component as this Embodiment, code | symbol "A" is attached | subjected to the end of the same code | symbol, and description of the structure is abbreviate | omitted.

  In the above-described embodiment, whether or not an abnormality signal is output is controlled based on the operating state of the drive source (attacker solenoid 148) after the abnormality detection by the magnetic sensor 202C.

  On the other hand, in the modification, the detection signal itself received from the magnetic sensor 202C is canceled based on the operation state of the drive source (attacker solenoid 148). That is, as shown in FIG. 8, the magnetic monitoring operation execution possibility determination unit 230 </ b> A is connected to the input signal reception cancellation unit 234. Further, the detection signal reception cancel unit 234 is connected to the detection signal reception unit 214A.

  For this reason, when the magnetic monitoring operation execution availability determination unit 230A recognizes the execution of the operation of the attacker solenoid 148, the detection signal reception cancellation unit 234 cancels (prohibits) reception by the detection signal reception unit 214A.

  FIG. 9 illustrates a fraud monitoring control routine by the fraud magnetic sensor 202C according to the modification.

  In step 270, it is determined whether or not the attacker solenoid 148 that is a drive source is in operation.

  If an affirmative determination is made in step 270, it is predicted that a magnetic force will be generated by the operation of the attacker solenoid 148, the process proceeds to step 272, the detection signal from the magnetic sensor 202C is canceled, and this routine ends.

  For this reason, the abnormal signal itself is not generated while the attacker solenoid 148 is operating.

  If a negative determination is made in step 270, the process proceeds to step 274 and the detection signal from the magnetic sensor 202C is captured. In the next step 276, the threshold value is read out, and then the process proceeds to step 278 to compare the signal strength of the detection signal with the threshold value.

  In the next step 280, it is determined whether or not the signal strength of the detection signal has exceeded a threshold value as a result of the comparison in step 278. Ends.

  On the other hand, if an affirmative determination is made in step 280, it is determined that there is a possibility of an illegal act, the process proceeds to step 282, the abnormality determination history information is updated, and then the process proceeds to step 284. In step 284, an abnormal signal is output and this routine ends.

  According to the present embodiment, the magnetism generated by the operation of the attacker solenoid 148 is detected as abnormal due to the operation of the attacker solenoid 148 because the magnetic sensor 202C cancels the detection itself. Therefore, it is possible to arrange without taking into consideration the relative positional relationship between the attacker 112 and the magnetic sensor 202C, and the degree of freedom in design can be increased.

  In the present embodiment, since the abnormality detection by the magnetic sensor 202C is prohibited during the operation of the attacker solenoid 148, it is possible to collect the true abnormality and leave it as a history. Therefore, the attacker 112 and the magnetic sensor 202C Can be used as information for subsequent designs, such as the relative positional relationship between the magnetic sensor 202C and the orientation of the detection surface of the magnetic sensor 202C.

  6 and 8 have been described using the attacker solenoid 148 as a driving source of the attacker 112 as an example, but the electric design provided in the special symbol start winning port (A) 130 and the special symbol start winning port (B) 134 is described. The same monitoring control is possible also in the drive source (solenoid or motor) which operates the tulip.

  In the above-described embodiments and modifications, the unauthorized monitoring control and the avoidance of monitoring while the electric accessory is moving are performed by so-called software processing. However, based on the driving state of the driving unit such as the attacker solenoid 148, so-called hardware For example, the wiring of the magnetic sensors 202A, 202B, and 202C may be intermittent.

  Moreover, in the said embodiment and modification, it is set as the structure which determines whether it is abnormal by comparing the intensity | strength of a magnetic detection signal with a threshold value in the fraud monitoring control part 204 (204A).

  That is, in the above-described embodiment and modification, the signal strength comparison unit 216 (216A), the signal strength threshold storage unit 218 (218A), and the magnetic abnormality presence / absence determination unit 220 (220A) include the detection signal reception unit 214 ( The signal of the magnetic sensor 202C received in 214A) is analog information, and when the signal intensity exceeds a predetermined signal intensity, control that is an abnormal signal is performed.

  On the other hand, the magnetic sensor 202C itself is configured to output digital information (binary signal “H / L signal”) when it receives an abnormal magnetic force and when it is not, and the detection signal receiving unit 214 Based on the received digital signal, it is determined whether or not an abnormal signal is to be output, and while the attacker solenoid 148 is excited, the output of the abnormal signal is avoided or the reception by the detection signal receiving unit 214 is canceled. It may be.
