  The following means are: “A pachinko machine, which is a kind of gaming machine, includes a main body frame that can be opened and closed with respect to an outer frame, and a front door that can be opened and closed with respect to the main body frame. The pachinko machine is provided with a control device and an open switch for detecting opening of the main body frame relative to the outer frame and opening of the front door relative to the main body frame. In the case of opening, the opening is detected by the opening switch, and the detection result is input to the control device.The control device assumes that the front door and the body frame are opened based on the detection result from the opening switch. If it is determined, a notification to that effect is executed using a speaker unit or a lamp unit (see, for example, Patent Document 1) Here, in a pachinko machine, the front door is opened and provided on the front side of the main body frame. Et An act of cheating on the game area is also assumed, and an act of cheating on the control device mounted on the back side of the main body frame by opening the main body frame is also assumed.

In order to do this, the pachinko machine is turned off after the store is closed, and after the pachinko machine is turned off, the power supply to the controller is stopped and the front door and the main frame are opened. The Accordingly, the notification process as described above is not executed, and it has been difficult for the conventional pachinko machine to cope with the fraud during the power shut-off. This is not limited to pachinko machines, but can also occur in other gaming machines having an opening / closing body such as a front door or a main body frame, such as slot machines and parrots. " It was made with the task to do.

Means 1. An opening / closing body (game machine main part 12 or front door frame 14) supported to be openable / closable with respect to a support target (outer frame 11 or main body frame 13);
An electric device (main control device 162, payout control device 242 and the like) that is provided on the back side or rear of the opening / closing body and operates based on electric power supplied from an external power source;
A moving body (the shielding portion 277b of the operating shaft 277) that moves to the first position in a situation where power is supplied from the external power source and that moves to the second position in a situation where the power supply is interrupted;
When the opening / closing body is opened, the movable body is allowed to move between the first position and the second position. When the opening / closing body is closed, the movable body is moved between the two positions. A restricting portion (protrusion 14b or protrusion 296) for restricting movement;
A gaming machine comprising: a detecting means (detecting device 265) for detecting the position of the moving body at least when power supply from the external power source is started.

  In the gaming machine of the means 1, the position of the moving body is detected at least when the supply of electric power is started. Based on the detection result, it can be confirmed whether the open / close body is opened or closed while the supply of power is stopped.

  When the opening / closing body is closed in the power supply state, the moving body is in the first position. When the supply of electric power is stopped while the opening / closing body is closed, the moving body tries to move to the second position. However, the movement of the moving body is regulated (prevented) by the regulating unit. Hereinafter, this state is referred to as a standby state. When the supply of power is resumed in this standby state, it is detected by the detection means that the moving body is present at the first position.

  On the other hand, when the opening / closing body is opened in the standby state, the moving body is allowed to move. For this reason, the moving body moves to the second position. When the opening / closing body is closed again, the restricting portion shifts to a state in which the movement of the moving body is restricted. That is, the movement of the moving body from the second position to the first position is restricted. When the supply of power is resumed in this state, the moving body tries to move to the first position. However, since the movement is hindered by the restricting portion, it remains in the second position. For this reason, it detects that it exists in the 2nd position by a detection means.

  As described above, when the position of the opening / closing body is switched in a state where the supply of electric power is stopped, a structural change resulting from the opening / closing of the opening / closing body can be caused. And this change can be structurally preserve | saved by closing an opening-closing body. Thereby, when the supply of electric power is started, it is possible to confirm the fact that the opening / closing body is opened in the standby state. In this way, it is possible to save the opening and closing facts of the opening and closing body from the structural side, thereby avoiding continuous power supply at night, etc., that is, contributing to energy saving (energy saving) However, fraudulent acts performed on the gaming machine can be suppressed.

  The “first position” and the “second position” shown in this means indicate a predetermined place, and may have a predetermined range in which the moving body can move.

  In addition, “at least when power supply is started from the external power source” indicates the time when power supply is started or after the start of power supply.

  Mean 2. 2. The gaming machine according to claim 1, wherein the presence or absence of the moving body at one of the first position and the second position is determined by the detecting means.

  In order to detect the position of the moving body, it is conceivable to set detection means corresponding to each position individually. Thus, if it is set as the structure which detects presence of a moving body in all the positions, while the position of a moving body can be grasped | ascertained reliably, the structure of a detection means may become complicated.

  As shown in this means, it is possible to determine whether or not there is a moving body at one of the first position and the second position, while ensuring the function of detecting the position of the moving body. Contributes to simplification of configuration. For example, when the moving body can be switched only between both the first position and the second position, the presence / absence of the moving body at one of the first position and the second position is determined. Thus, it is possible to grasp directly or indirectly where the moving body is. Thereby, it can contribute to simplification of the structure of a detection means, ensuring the detection of the position of a moving body.

Means 3. A second position biasing means (self-weight of the operation shaft 277) for constantly biasing the moving body toward the second position;
First position urging means (solenoid 276 of the operation mechanism 275) for urging the movable body toward the first position in a situation where power from the external power source is supplied;
The gaming machine according to means 1 or 2, wherein an urging force of the first position urging means is set larger than an urging force of the second position urging means.

  In order to make the moving body movable at both the first position and the second position, it is preferable to provide two urging means as shown in this means. In a state where electric power is supplied, the urging force of the first position urging means exceeds the urging force of the second position urging means, and the moving body can move to the first position. On the other hand, in a state where the supply of electric power is stopped, the moving body can move to the second position by the urging force of the second position urging means. Thereby, a practically preferable configuration can be realized. For example, an elastic member such as a spring may be used as the second position biasing unit, and an electric actuator such as a solenoid actuator may be used as the first position biasing unit.

  Means 4. The gaming machine according to any one of means 1 to 3, wherein the second position is set lower than the first position.

  According to the means 4, since the second position is set below the first position, the moving direction component of the moving body includes the vertical direction component. Thereby, the movement to the 2nd position from the 1st position using the dead weight fall of a moving body is enabled, and the composition for moving a moving body can be simplified.

  Particularly in combination with the means 2 (configuration having the first position urging means and the second position urging means), the weight of the moving body may be used as the second position urging means.

  Means 5. The restricting portion is provided to be switchable between a restricting state for restricting movement of the moving body between both positions and an allowable state for allowing the moving body to move with the opening and closing of the opening and closing body. A gaming machine according to any one of means 1 to means 4 characterized by the above.

  According to the means 5, it is not necessary to separately provide power for switching the state of the restricting portion by enabling the restricting portion to be switched in accordance with opening and closing of the opening / closing body. That is, even in a state where the supply of power is stopped, the switching of the restricting portion can be realized from the mechanical side. For example, the restricting portion may be configured to move following the opening / closing movement of the opening / closing body.

Means 6. The restricting unit is set to be switchable between a position on the moving path of the moving body and a position away from the moving path,
The gaming machine according to any one of the means 1 to 5, wherein one of the support object and the opening / closing body includes the moving body, and the other includes the restriction portion.

  According to the means 6, the restricting unit is configured to restrict the movement of the moving body by being positioned on the moving path of the moving body and to allow the moving body to move by being separated from the moving path of the moving body. Can do. Since the restricting portion and the moving body are provided separately for the opening / closing body and the support target, the positional relationship between the two can be easily changed with the opening / closing operation of the opening / closing body. That is, the relative position of the restricting portion with respect to the moving body can be easily switched. This can contribute to the realization of a simple configuration. For example, by making the displacement direction of the relative position of both the same as the opening / closing direction of the opening / closing body, the displacement of the relative position due to opening / closing of the opening / closing body can be positively utilized. Thereby, it can be set as the structure which is easy to ensure the displacement amount of a control part, a mobile body (specifically the movement path | route), and a relative position, and can contribute to realization of more reliable switching.

  Mean 7 The opening / closing body is rotatably attached to the object to be supported, and at least the moving body and the restricting portion are disposed on a rotating front end side of the opening / closing body. The gaming machine described in 1.

  According to the means 7, at least the moving body and the restricting portion are arranged on the rotating front end side of the opening / closing body. For this reason, compared with the case where both are arrange | positioned at the rotation base end side, the displacement amount of the relative position with respect to the open angle of an opening-closing body can be ensured easily. That is, even when the opening angle of the opening / closing body is small, it is easy to shift to a state where movement of the moving body is permitted. Therefore, it is hard to be influenced by the fraud detection function due to the opening degree of the opening / closing body. For example, it is possible to suitably suppress the inconvenience that it is difficult to release the restricted state by the restricting unit by performing a fraud by slightly opening and closing the opening / closing body. In particular, in a gaming machine such as a pachinko machine having a game area where game balls flow down, fraud can occur when the opening / closing body is slightly opened. However, by applying the above-described configuration, it is possible to ensure the suppression effect against such illegal acts.

Means 8. The detection means includes a transmission unit (light emitting element 266) that emits a signal when power is supplied from an external power source, and a reception unit (light receiving element 267) that can receive the signal with the opening / closing body closed. And at least
The gaming machine according to claim 7, wherein in the state where the moving body is in the second position, a signal emitted from the transmitting unit is blocked by the moving body before reaching the receiving unit.

  According to the means 8, it is possible to detect that the moving body exists in the second position by being blocked by the moving body before the signal emitted from the transmitting section reaches the receiving section. In such a case, it can be understood that the opening / closing body may have been opened while the supply of power is stopped.

  Further, a signal emitted from the transmission unit in a state where power is supplied reaches the reception unit only when the opening / closing body is closed. Thereby, it can be detected that the opening / closing body is in a closed state. On the other hand, no signal is received when the open / close body is opened. Thereby, it can be detected that the open / close body is in an open state. In other words, the detection means has a function of monitoring the opening of the opening / closing body in both the situation where the power supply from the external power supply is interrupted and the situation where the power supply is performed. Compared to the case of realizing with the configuration of, it is possible to suppress an increase in the number of parts of the gaming machine.

  For example, the transmitting unit may be a light emitting unit that emits light, and the receiving unit may be a light receiving unit that receives light.

  Means 9. A signal passing path through which a signal emitted from the transmitter is allowed to pass only when the opening / closing body is closed, and the signal passing path is set at least in a boundary region between the opening / closing body and the support target; A gaming machine according to claim 8, characterized in that

  In order to achieve a configuration in which signals can be transmitted and received only when the opening / closing body is closed, as shown in this means, it is preferable to set the signal passage path at least in the boundary region between the opening / closing body and the support target. Thereby, the opening / closing detection of an opening / closing body is realizable with a simple structure.

Means 10. The detection means includes
A light emitting part (light emitting part 266) that is disposed on at least one of the opening and closing body and the support object and emits light toward the other, and a light receiving part (light receiving part 267) that receives the light;
A reflecting portion (reflecting surfaces 274b and 274c of the light reflecting member 274) that is provided on the other side and reflects light from the light emitting portion toward the light receiving portion in a state in which the opening / closing body is closed with respect to the support target; Have
The moving body includes a shielding part (shielding part 277b) that shields light,
The game according to means 7, wherein the shielding part is located between at least one of the light emitting part and the light receiving part and the reflecting member in a state where the moving body is in the second position. Machine.

  According to the means 10, it is possible to detect that the moving body is present at the second position by being blocked by the shielding section of the moving body before the light emitted from the light emitting section reaches the light receiving section. . In such a case, it can be understood that the opening / closing body may have been opened while the supply of power is stopped.

  In addition, light emitted from the light emitting unit in a state where power is supplied reaches the light receiving unit only when the opening / closing body is closed. Thereby, it can be detected that the opening / closing body is in a closed state. On the other hand, when the opening / closing body is opened, no light is transferred. Thereby, it can be detected that the open / close body is in an open state. In other words, the detection means has a function of monitoring the opening of the opening / closing body in both the situation where the power supply from the external power supply is interrupted and the situation where the power supply is performed. The number of parts of the gaming machine can be reduced as compared with the configuration provided in.

  As described above, adding the detection means may cause complication of the configuration. In particular, there is a concern that the wiring process and the like will become complicated, which will complicate the manufacturing process of the gaming machine and deteriorate the workability during maintenance. In this means, it is possible to prevent the wiring from being complicated by providing the light emitting part and the light receiving part together on the opening / closing body or the support target. For example, a light emitting unit and a light receiving unit may be provided on the support target, and a reflection unit may be provided on the opening / closing body. Thereby, since the increase in the weight of an opening / closing body can be suppressed, the opening detection of an opening / closing body can be implement | achieved, suppressing the influence on the installation etc. of an opening / closing body. Further, in recent years, the reusability of gaming machines has been improved by exchanging the opening and closing body and using the support object in common when changing models. As described above, by arranging the light emitting unit and the light receiving unit together as a support target, it is possible to contribute to improvement in reusability of the components while increasing the number of components.

  Means 11. The detecting means includes a switch (switch 410) that contacts the moving body when the moving body is in one of the first position and the second position. The gaming machine according to any one of means 7.

  According to the means 11, it can be detected whether the moving body exists in either the first position or the second position depending on whether or not the switch and the moving body hit each other. Compared with the case where the position of the moving body is detected by using an optical sensor or the like, it is easy to suppress the power required to operate the detection device. Thereby, it can contribute to the contribution improvement to energy saving.

Means 12. The switch is configured to be displaceable between both a separated position separated from the moving body and a contact position contacting the moving body,
12. The gaming machine according to claim 11, wherein the displacement direction of the switch is set in the same direction as the moving direction of the moving body.

  According to the means 12, the moving direction of the moving body is the same as the displacement direction of the switch. Thereby, it becomes easy to generate a predetermined load in the contact direction between the moving body and the switch. For example, even when the gaming machine shakes, it is easy to maintain the contact state between the moving body and the switch.

  In particular, the combination of the means 3 and the means 4 may be configured such that the two come into contact with each other when the moving body is in the second position. Thereby, the contact state of the moving body and the switch can be more suitably secured by the dead weight of the moving body or the second position urging means.

  Means 13. Provided with notification means (error display lamp section 24, speaker section 26, symbol display apparatus 91, etc.) that is connected to the external power source and notifies the occurrence and possibility of predetermined fraud based on the detection result of the detection means. A gaming machine according to any one of means 1 to means 12 characterized by the above.

  According to the means 13, by providing the notification means in the gaming machine, detection of unauthorized opening / closing of the opening / closing body and notification thereof can be completed by the gaming machine. Thereby, it is possible to promote the introduction of a gaming machine having a fraud countermeasure function regardless of the business form of the hall. For example, in a configuration in which a gaming machine has a picture display device (picture display device 91), a lamp unit (error display lamp unit 24), a speaker (speaker unit 26), and the like, if these picture display devices are used as notification means. Good.

Means 14. The support object has a shielding portion (opening flange 13a) that covers at least the outer peripheral edge of the opening / closing body on the rotation tip side from the side of the gaming machine,
A gaming machine in which the overlap between the shielding portion and the opening / closing body is maintained until the rotation of the opening / closing body reaches a predetermined angle,

The gaming machine according to means 6 or 7, characterized in that it is set.

  According to the means 14, when the opening / closing body is rotated in the standby state, the movement restriction of the moving body is first released, and the moving body can be moved to the second position. Further, by rotating the opening / closing body, the overlap between the shielding part and the opening / closing body is released, and the part of the opening / closing body facing the support target can be visually recognized. That is, the restricting portion or the like can be visually recognized. In this way, the movement of the moving body is blocked by the overlap between the opening / closing body and the shielding portion, so that unauthorized access to the moving body or the like from the outside of the gaming machine can be made difficult. Therefore, the unauthorized opening detection of the opening / closing body can be made more suitable.

  Means 15. The detection means detects the position of the moving body in any of a situation where power is supplied from the external power source and a situation where the power supply is interrupted. The gaming machine according to any one of means 14.

Therefore, first, the first monitoring device 250 will be described in detail, and then the differences described above will be described. 14 is an exploded perspective view of the first monitoring device 250 viewed from the front of the pachinko machine 10, FIG. 15 is an exploded perspective view of the first monitoring device 250 viewed from the rear of the pachinko machine 10, and FIG. FIG. 16B is a partial cross-sectional view taken along the line AA of FIG.

  The first monitoring device 250 includes a housing case body 251 and a lid case body 280. A housing 252 that can accommodate various configurations to be described later is formed by fixing both the case bodies 251 and 280 with fasteners such as screws. The housing 252 (both case bodies 251 and 280) is formed of a transparent synthetic resin material having optical transparency, and the inside of the housing 252 is visible. Thereby, the internal confirmation of the 1st monitoring apparatus 250 by maintenance etc. is facilitated. As described above, by facilitating the internal confirmation, it is easy to find out even if a fraudulent act is performed on the first monitoring device 250 itself and the monitoring function is hindered. It has become. Therefore, contribution to further improvement of crime prevention can be expected.

  The first monitoring device 250 is disposed at the upper corner of the resin base 71 with the housing case body 251 as the front side and the lid case body 280 as the rear side. In such a state, the resin base 71 is fixed to the back surface by a fastener such as a bolt.

  The housing case body 251 has a top plate portion 253, a bottom plate portion 254, a front plate portion 255, a left plate portion 256, and a right plate portion 257, and is formed in a substantially box shape that is opened to the rear of the pachinko machine 10 as a whole. ing. The front plate portion 255 is substantially parallel to the back surface of the resin base 71. The front plate portion 255 is formed with an upper extension portion 258 extending upward from the boundary with the top plate portion 253 and a lower extension portion 259 extending downward from the boundary with the bottom plate portion 254. The extending portions 258 and 259 are in contact with the back surface of the resin base 71.

  The extended portions 258 and 259 are provided with round holes 258a and 259a into which the cylindrical boss portions 71a formed in the resin base 71 are fitted (see FIG. 16). The first monitoring device 250 is vertically and horizontally positioned by fitting the boss portion 71a into the round holes 258a and 259a.

  In addition, a projecting portion 260 projecting forward in a step shape is formed in the lower portion of the front plate portion 255, and an opening 71 b corresponding to the projecting portion 260 is formed in the resin base 71. The opening 71b penetrates in the front-rear direction, and the inner periphery thereof has substantially the same shape as the outer periphery of the overhang 260. By fitting the overhanging portion 260 into the opening 71b, the boundary portion between the resin base 71 and the first monitoring device 250 has a crank shape. As a result, the inconvenience that an unauthorized tool or the like is inserted from the boundary portion between the opening 71b and the overhanging portion 260 is suppressed. Further, the front surface of the resin base 71 and the front surface of the overhang portion 260 are set to be substantially on the same plane. That is, the overhang portion 260 is configured not to protrude forward from the resin base 71. Thereby, it is possible to avoid the disadvantage that the first monitoring device 250 is displaced due to the overhanging portion 260 being caught during maintenance work or the like.

  Inside the housing 252 (specifically, inside the housing case body 251), a detection device 265 that detects the open / closed state of the front door frame 14 and an operation mechanism 275 that continuously operates when power is supplied are installed. Has been.

  The detection device 265 will be described in detail. The detection device 265 is disposed behind the opening 71 b of the resin base 71, that is, behind the overhang portion 260. More specifically, it is disposed on the rotating front end side of the front door frame 14 inside the housing case body 251. The detection device 265 houses a light emitting element 266 that emits light (specifically, a light emitting diode that emits infrared light), a light receiving element 267 that receives light from the light emitting element 266 (specifically, a phototransistor), and both these elements 266 and 267 And a container 268 to be used.

  The container 268 has a substantially rectangular parallelepiped main body portion 269, and the front surface thereof is arranged in parallel with the front plate portion 255. Projecting portions 269a and 269b projecting in the left-right direction are formed at the lower portion of the main body portion 269. Each projecting portion 269a, 269b has a plate shape parallel to the bottom plate portion 254. The housing case body 251 is formed with a first guide groove 270 into which the protruding portions 269a and 269b are fitted. These first guide grooves 270 face each other and extend in the front-rear direction, and are opened to the rear of the pachinko machine 10 at the rear end portion. By inserting the protrusions 269a and 269b from the rear end side of the first guide groove 270 and pushing in the detection device 265, the detection device 265 is mounted. Thus, the protrusions 269a and 269b are inserted into the first guide groove 270, so that the outer peripheral surfaces of the protrusions 269a and 269b come into contact with the inner peripheral surface of the first guide groove 270. Thereby, the movement of the detection device 265 in the vertical direction and the horizontal direction is restricted.

  In addition, an abutting portion 271 with which the container 268 hits is provided at the front portion of the first guide groove 270. The abutting portion 271 protrudes inward of the housing case body 251 and has an upper abutting surface 271 a parallel to the inner surface of the bottom plate portion 254 and a rear abutting surface 271 b parallel to the inner surface of the front plate portion 255. doing. When the detection device 265 is pushed along the first guide groove 270, the container 268 and the rear contact surface 271b come into contact with each other. As a result, the forward movement of the detection device 265 is restricted. In this state where forward movement is restricted, a predetermined gap is secured between the front plate portion 255 of the housing case body 251 and the detection device 265. The container 268 is fixed to the container case 251 with a fastener such as a screw in a state where movement in the forward, left-right, and vertical directions is restricted as described above. That is, the detection device 265 is attached to the housing 252.

  Through holes 269c and 269d penetrating in the front-rear direction are arranged side by side on the main body 269 of the container 268 with a predetermined distance therebetween. A light emitting element 266 and a light receiving element 267 are fitted in the through holes 269c and 269d with the light emitting part and the light receiving part facing forward. Each through-hole 269c, 269d is disposed above the upper contact surface 271a (contact portion 271), and the contact portion 271 does not block the passage of light between the elements 272, 273. For example, light emitted from the light emitting element 266 is emitted from the housing case body 251 without being blocked by the contact portion 271, and is irradiated toward the back surface of the front door frame 14. The central axes of the through holes 269c and 269d are orthogonal to the front plate portion 255, and the central axes of the elements 266 and 267 are also orthogonal to the front plate portion 255. For this reason, when the light from the light emitting element 266 enters the front plate portion 255, it is difficult to be refracted or reflected. Details of the light path will be described later.

  As shown in FIGS. 2 and 16, a light reflecting member 274 that reflects light from the light emitting element 266 toward the light receiving element 267 is provided in front of the detection device 265, that is, on the back side of the front door frame 14. ing. The light reflecting member 274 is fixed to the front door frame 14 by a fastener such as a screw in a state where the light reflecting member 274 is accommodated in the accommodating recess 14 a formed in the front door frame 14, and the protrusion of the front door frame 14 from the back surface is prevented. It is suppressed. The light reflecting member 274 is constituted by a glass prism having light permeability. Specifically, as shown in FIG. 16 (b), a facing surface 274a that faces the detection device 265 and is orthogonal to the light traveling direction, and a predetermined angle with respect to the light traveling direction (in this embodiment, A first reflection surface 274b and a second reflection surface 274c that are inclined at 45 °. Both reflection surfaces 274b and 274c are provided on the front side of the pachinko machine 10 with respect to the opposing surface 274a. The first reflecting surface 274b is disposed in front of the light emitting element 266, the second reflecting surface 274c is disposed in front of the light receiving element 267, and both the reflecting surfaces 274b and 274c are opposed to each other. That is, the reflecting surfaces 274 b and 274 c have a substantially C shape that spreads backward in the plan view of the pachinko machine 10.

  Hereinafter, a passage path of light emitted from the light emitting element 266 will be described with reference to FIG. In FIG. 16B, an outline of the light passage path is indicated by a one-dot chain line arrow.

  The light emitted from the light emitting element 266 passes through the front plate portion 255 of the housing case body 251 and is irradiated on the back surface of the front door frame 14. Specifically, most of the light enters the facing surface 274 a of the light reflecting member 274. The light that has passed through the facing surface 274a is reflected by the first reflecting surface 274b and its traveling direction changes. That is, it is reflected toward the second reflecting surface 274c. The light that has reached the second reflecting surface is reflected so that its traveling direction is directed toward the rear of the pachinko machine 10. The light whose traveling direction is reversed in this way passes through the facing surface 274a again and is emitted toward the front plate portion 255. The light that has passed through the front plate portion 255 reaches the light receiving element 267. It is also possible to change the traveling direction of light using a mirror or the like instead of the light reflecting member 274.

  Next, the operation mechanism 275 will be described in detail. As shown in FIGS. 14 to 16, the operation mechanism 275 is disposed on the side of the detection device 265, and as a main configuration, a solenoid 276 provided as a power source of the operation mechanism 275, and the solenoid 276. And an operating shaft 277 inserted into the.

  The solenoid 276 has a substantially cylindrical shape extending in the vertical direction, and a mounting portion 278 for the housing case body 251 is provided on the upper portion thereof. The attachment portion 278 has a plate shape parallel to the top plate portion 253 of the housing case body 251 and is fitted in a second guide groove 279 formed in the top plate portion 253 and the left side plate portion 256. These second guide grooves 279 face each other and extend in the front-rear direction, and are opened to the rear of the pachinko machine 10 at the rear end portion. The operating mechanism 275 is mounted by inserting the mounting portion 278 from the rear end side of the second guide groove 279 and pushing the solenoid 276. In this manner, the mounting portion 278 is inserted into the second guide groove 279, so that the outer peripheral surface of the mounting portion 278 and the inner peripheral surface of the second guide groove 279 come into contact with each other. Thereby, the movement of the operation mechanism 275 in the vertical direction and the horizontal direction is restricted. By pushing the operating mechanism 275 along the guide groove 279, the mounting portion 278 and the front plate portion 255 of the housing case body 251 come into contact with each other, and movement to the front of the pachinko machine 10 is restricted. The movement mechanism 275 is fixed to the housing case body 251 with a fastener such as a screw in such a state that movement in each direction is restricted. In the present embodiment, the second guide groove 279 is provided to improve the mounting workability of the operation mechanism 275. However, a configuration in which these are not provided is also possible.

  The operation shaft 277 has an iron cylindrical portion 277a extending in the vertical direction. Most of the cylindrical portion 277 a is accommodated in the solenoid 276. The central axis of the cylindrical portion 277 a and the central axis of the solenoid 276 overlap each other, and the operation shaft 277 can move in the direction of the central axis of the solenoid 276. The lower end portion of the operating shaft 277 protrudes to the outside of the solenoid 276, and a plate-like shielding portion 277 b and a crank portion 277 c that offsets the shielding portion 277 b from the operating shaft 277 to the front of the pachinko machine 10. It is integrally molded. In the present embodiment, the cylindrical portion 277a, the shielding portion 277b, and the crank portion 277c of the operation shaft 277 are integrally formed, but they can be individually formed. For example, only the cylindrical portion 277a may be made of iron, and the shielding portion 277b and the crank portion c may be made of synthetic resin.

  The shielding portion 277b is formed substantially in parallel with the front plate portion 255, and moves in parallel with the front plate portion 255 following the vertical movement of the operation shaft 277. Further, the shielding portion 277b is disposed on the front side of the detection device 265 by the crank portion 277c, and a working space is secured by a space formed between the detection device 265 and the front plate portion 255. . The lower end portion of the shielding portion 277b contacts the upper contact surface 271a at the lower limit position. In such a contact state, the shielding portion 277 b is configured to overlap the light receiving element 267 in the front view of the pachinko machine 10. That is, the front side of the light receiving element 267 is covered. On the other hand, in a state where the shielding part 277b is at the upper limit position, the lower end part of the shielding part 277b is set to be above the light receiving element 267. That is, the front side of the light receiving element 267 is not covered. The shielding portion 277b is provided with a coating that absorbs light (a coating with low light reflectance), and the inconvenience that light from another light source is reflected by the shielding portion 277b and reaches the light receiving element 267 is avoided. ing. In this embodiment mode, the shielding portion 277b overlaps only with the light receiving element 267. However, the shielding portion 277b may overlap with the light emitting element 266 or may overlap with both the light receiving element 267 and the light emitting element 266.

  As shown in FIG. 16, the operating shaft 277 is held at the upper limit position (hereinafter also referred to as the first position) of the operating range in a state where power is supplied to the solenoid 276. Specifically, the output of the solenoid 276 is set large enough to lift the operating shaft 277 against gravity. In a state where the supply of electric power is stopped, the operation shaft 277 is lowered by its own weight and held at the lower limit position (hereinafter also referred to as a second position) of the operation range. Specifically, the operating shaft 277 is held at the second position by the shielding portion 277b coming into contact with the upper contact surface 271a. In other words, the position of the operating shaft 277 is switched between the first position and the second position depending on whether or not power is supplied. In other words, the position of the shielding portion 277b is switched between the first position and the second position in accordance with the position switching of the operation shaft 277.

  A predetermined gap region is set between the lower end portion of the shielding portion 277b at the first position and the upper end portion of the shielding portion 277b at the second position. That is, the operating distance dimension of the operating shaft 277 is set larger than the length dimension in the axial direction of the shielding portion 277b. An insertion hole 260a penetrating inward and outward (ie, in the front-rear direction of the pachinko machine 10) is formed in a part of the front plate portion 255 (specifically, the overhanging portion 260) that overlaps the gap region in the front view of the pachinko machine 10. Yes. On the back surface of the front door frame 14, a projection 14b that can be inserted into the insertion hole 260a is provided. The protrusion 14 b is integrally formed with the front door frame 14 and extends rearward of the pachinko machine 10. The tip of the projection 14b is located slightly behind the rear end of the shielding part 277b. Since the projection 14b is provided on the front door frame 14 as described above, it moves as the front door frame 14 rotates. That is, the protrusion 14b is inserted into the insertion hole 260a when the front door frame 14 is closed to the main body frame 13, and is not inserted into the insertion hole 260a when the front door frame 14 is opened by a predetermined amount or more. It becomes a state.

  In a state where the projection 14b is inserted through the insertion hole 260a, that is, in a state where the front door frame 14 is closed, the shielding portion 277b and the projection 14b come into contact with each other, so that both the first position and the second position of the shielding portion 277b Movement between them is regulated. Specifically, when the projection 14b is inserted into the insertion hole 260a in a state where the shielding part 277b is in the first position, the movement of the shielding part 277b to the second position is restricted. Further, when the projection 14b is inserted while the shielding part 277b is in the second position, the movement of the shielding part 277b to the first position is restricted.

  As described above, the front door frame 14 is provided so as to be rotatable with respect to the main body frame 13. In such a case, there is a possibility that the relative positions of the projection 14b, the shielding portion 277b, and the insertion hole 260a may vary before the hook metal fitting 63 and the hook receiving metal fitting 132 of the front door frame 14 are brought into the locked state. For this reason, there is a concern that the closing operation of the front door frame 14 is hindered by the hooks 14b and the like being caught. However, in the present embodiment, the projection 14b has a predetermined clearance from the shielding portion 277b in both positions, and the insertion hole 260a has a tapered shape that expands in front of the pachinko machine 10. Yes. Thereby, the catch at the time of protrusion 14b insertion is suppressed, and the workability | operativity at the time of the front door frame 14 closing is ensured.

  Next, the relative relationship between the protrusion 14b and the shielding part 277b will be described in detail. In the state in which the front door frame 14 is closed, the rear end of the protrusion 14b protrudes slightly rearward from the rear end of the shielding portion 277b. For this reason, even if the front-rear direction position of the front door frame 14 slightly varies, the function of the protrusion 14b is ensured. When opening the front door frame 14, the projection 14 b moves to a position where it does not overlap with the shielding part 277 b in the plan view of the pachinko machine 10 by opening it at a predetermined angle or more, thereby restricting the movement of the shielding part 277 b. Is released.

  An opening flange 13 a extending in front of the pachinko machine 10, that is, toward the front door frame 14, is integrally formed at the peripheral edge of the main body frame 13. By this opening flange 13a, the peripheral edge of the main body frame 13 and the peripheral edge of the front door frame 14 are configured to overlap in a side view and a plan view of the pachinko machine 10. Thus, by setting both to overlap, the inconvenience that an improper tool etc. are inserted from the boundary part of the main body frame 13 and the front door frame 14 is suppressed. The amount of overlap between the projection 14b and the shielding portion 277b described above is set smaller than the amount of overlap between the opening flange 13a and the front door frame 14. More specifically, the distance dimension in the front-rear direction from the front surface of the shielding part 277b to the rear end part of the protrusion 14b is larger than the distance dimension in the front-rear direction from the front end edge of the opening flange 13a to the rear end edge of the front door frame 14. Even smaller is set. For this reason, when the front door frame 14 is rotated and the projection 14b and the shielding portion 277b are not overlapped with each other, the boundary portion between the main body frame 13 and the front door frame 14 is not exposed by the opening flange 13a. That is, when the front surface of the main body frame 13 becomes visible from the boundary portion between the main body frame 13 and the front door frame 14, the movement restriction of the shielding portion 277b by the protrusion 14b is already released. Has been.

  Next, a main configuration of the lid required case body 280 will be described. The lid case body 280 has a top plate portion 281, a bottom plate portion 282, a back plate portion 283, a left side plate portion 284, and a right side plate portion 285, and is formed in a substantially box shape opened to the front of the pachinko machine 10 as a whole. Has been. The rear end opening edge of the housing case body 251 is housed in the opened portion of the lid case body 280. A relay substrate 286 that is electrically connected to the detection device 265 and the like by a harness (not shown) is disposed inside the lid case body 280. The relay substrate 286 has a substantially plate shape parallel to the back plate portion 283, and is fixed to the inner surface of the back plate portion 283 with a fastener such as a screw.

  A communication hole 287 penetrating inward and outward is formed behind the relay board 286, that is, in a portion of the back plate portion 283 facing the relay board 286. A connector 288 is disposed behind the communication hole 287. That is, the relay board 286 and the connector 288 are provided to face each other with the communication hole 287 interposed therebetween, and the relay board 286 and the connector 288 are connected by a harness or the like (not shown). The connector 288 is fixed to the back surface of the back plate portion 283 with a fastener such as a screw in a state where the insertion port faces the back of the pachinko machine 10. The first monitoring device 250 and the main control device 162 are electrically connected through a connector 288 by a harness (not shown). In the present embodiment, the lid case body 280 has a light-transmitting configuration as described above, thereby making it easy to confirm fraud with the first monitoring device 250. However, the lid case body 280 may be configured to have no light transmittance. In such a case, the lid case body 280 may be formed of, for example, an opaque synthetic resin material or a light metal material such as aluminum.

  Hereinafter, detection of opening of the front door frame 14 by the first monitoring device 250 will be described with reference to FIG. 17A shows the closed state (normal state) of the front door frame 14 in the power supply state, FIG. 17B shows the open state of the front door frame 14 in the power supply state, and FIG. FIG. 17 (d) shows the open state of the front door frame 14 when the power supply is stopped, and FIG. 17 (e) shows the front door frame 14 when the power supply is stopped. FIG. 17 (f) shows a state in which power supply is started after the front door frame 14 is opened and closed while the power supply is stopped.

  First, detection of opening of the front door frame 14 in a state where electric power is supplied to the pachinko machine 10 will be described. When the front door frame 14 is opened, the work is performed in the order of FIG. 17A → FIG. 17B → FIG. 17A.

  As shown in FIG. 17A, in a state where electric power is supplied to the first monitoring device 250, that is, in a state where the solenoid 276 is energized, the solenoid 276 is excited. As a result, the operating shaft 277 is held at the first position. In such a state, the shielding portion 277 b does not exist in front of the light receiving element 267, and the light emitted from the light emitting element 266 reaches the light receiving element 267 via the light reflecting member 274. When the light reaches the light receiving element 267, a light reception signal is output to the relay board 286. By reading this light reception signal, it is detected that the front door frame 14 is in a closed state.

  When the front door frame 14 is opened while electric power is supplied to the first monitoring device 250, the relative positions of both the elements 266, 267 and the light reflecting member 274 change. In such a case, the light emitted from the light emitting element 266 does not reach the light reflecting member 274 or even if it reaches the light reflecting member 274, the reflected light is emitted toward a part other than the light receiving element 267. For this reason, light from the light emitting element 266 does not reach the light receiving element 267. Therefore, a predetermined light reception signal is not output, and it can be detected that the front door frame 14 is closed by reading a change in the light reception signal.

  As described above, by allowing the opening of the front door frame 14 to be detected in a state where power is supplied, unauthorized opening of the front door frame 14 performed during hall operation can be suppressed. Therefore, it can contribute to suppression of fraud against the pachinko machine 10.

  When the supply of power to the first monitoring device 250 is stopped when the store is closed, the supply of power to the solenoid 276 is stopped and the excitation state is released. In such a case, the operation shaft 277 (specifically, the shielding portion 277b) moves downward due to its own weight and comes into contact with the protrusion 14b. The shielding portion 277b comes into contact with the protrusion 14b, and thus the downward movement is restricted. That is, the movement to the second position is hindered. When the supply of electric power is started again in this state, the solenoid 276 is in an excited state, and the operating shaft 277 is lifted upward by overcoming its own weight action. In this case, since the light from the light emitting element 266 can reach the light receiving element 267, it can be detected that the front door frame 14 is in a closed state. That is, the state transitions as shown in FIG. 17 (a) → FIG. 17 (c) → FIG. 17 (a) indicates that the front door frame 14 was not opened while the power supply was stopped. It can be detected.

  A case where the front door frame 14 is opened and closed while the supply of electric power is stopped will be described. As the front door frame 14 opens and closes, the relative position between the protrusion 14b and the shielding portion 277b changes in the order of FIG. 17C → FIG. 17D → FIG.

  As the front door frame 14 is opened, the projection 14b moves away from the first monitoring device 250, so that the shield 277b loses its support and moves downward (ie, the second position) due to its own weight. When the shielding portion 277b moves downward, the shielding portion 277b hits the upper contact surface 271a, and further downward movement is restricted. When the front door frame 14 is closed again in such a state, the projection 14b returns to the original position, and the upward movement of the shielding portion 277b is restricted. In this state, the shielding portion 277b is positioned in front of the light receiving element 267, and its vertical movement is restricted by the protrusion 14b and the upper contact surface 271a. Thus, by making the shielding part 277b immovable from the second position, the fact that the front door frame 14 has been opened can be stored mechanically.

  When the supply of power is started in a state where the movement of the shielding part 277b from the second position is restricted, the solenoid 276 is excited and the shielding part 277b tends to move upward (that is, the first position). However, the shielding part 277b hits the protrusion 14b and is prevented from moving. That is, the state where the light receiving element 267 is covered by the shielding portion 277b is continued. When the supply of power is started, the light emitting element 266 starts to emit light. Light emitted from the light emitting element 266 is irradiated toward the light receiving element 267 through the light reflecting member 274. However, the light reaching the light receiving element 267 is blocked by the shielding portion 277b positioned in front of the light receiving element 267. For this reason, the output of the light reception signal is suppressed, and it is detected that the front door frame 14 is open. Actually, the front door frame 14 is in a closed state, but it is possible to detect the fact that it has been opened when the power is shut off. Details of the monitoring process in the main controller 162 will be described later.

  As described above, in the state where the opening of the front door frame 14 at the time of power interruption is detected, by opening the front door frame 14 again, the protrusion 14b is separated from the first monitoring device 250, and the shielding part 277b is in the first position. Move to. That is, the movement restriction of the shielding part 277b is released. Thus, by operating the front door frame 14 in the order of FIG. 17 (f) → FIG. 17 (b) → FIG. 17 (a), the unauthorized opening detection state is released and the normal state is restored. Since the unauthorized opening detection state is reset by opening the front door frame 14, there is no need to provide a reset switch or the like, which can contribute to simplification of the configuration. Further, since the opening of the front door frame 14 is performed by a predetermined operation (key), it is possible to suppress the inconvenience that the unauthorized opening detection state is illegally released.

  Similarly to the first monitoring device 250, the second monitoring device 290 includes a housing case body 251, a lid case body 280, a detection device 265, an operation mechanism 275, a relay board 286, and a connector 288. A protrusion and a light reflecting member corresponding to the second monitoring device 290 are provided on the main body frame 13. Hereinafter, a different part from the 1st monitoring apparatus 250 is demonstrated concretely based on FIG. 18 is a partial cross-sectional view taken along the line CC of FIG.

  The insertion hole 260a of the first monitoring device 250 is exposed to the front of the pachinko machine 10, whereas the insertion hole 260a of the second monitoring device 290 is exposed to the rear of the pachinko machine 10. Specifically, the second monitoring device 290 is fixed in a state in which the housing case body 251 is fitted in the opening 71c formed in the resin base 71 with the front case body 251 and the lid case body 280 rearward. In such a state, the front plate portion 255 of the housing case body 251 protrudes rearward from the back surface of the resin base 71. That is, the insertion hole 260a of the front plate portion 255 is opened rearward. A base material 295 facing the front plate portion 255 is provided at the lower portion of the outer frame 11. The base material 295 has a plate shape and is fixed to the outer frame 11 with a fastener such as a screw. A protrusion 296 that can be inserted into the insertion hole 260 a is formed on the front surface of the base material 295. A recess 297 that is recessed toward the rear of the pachinko machine 10 is formed below the protrusion 296, that is, behind the detection device 265. The light reflecting member 298 is accommodated in the recess 297 and is fixed by a fastener such as a screw.

  In the second monitoring device 290, the second monitoring device 290 itself moves as the gaming machine main part 12 rotates with respect to the outer frame 11. That is, the positions of the protrusion 296 and the light reflecting member 298 are fixed, and the relative position of the two changes as the second monitoring device 290 moves. Similar to the first monitoring device 250, the second monitoring device 290 can detect the open state of the gaming machine main body 12 by changing the relative position between the protrusion 296 and the light reflecting member 298. The operation mode is the same as the operation mode of the first monitoring device 250 shown in FIG.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 19, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  A main control board 301 provided in the main controller 162 incorporates a main control circuit 302 and a power failure monitoring circuit 303 (power failure monitoring circuit). The main control circuit 302 is equipped with a CPU 311.

  The CPU 311 temporarily stores various control programs executed by the CPU 311 and a ROM 312 (nonvolatile information storage means) that stores fixed value data, and various data when the control program stored in the ROM 312 is executed. A RAM 313 (volatile information storage means), which is a memory for storing data, and various circuits such as an interrupt circuit, a timer circuit, and a data input / output circuit are incorporated. Note that the CPU 311, the ROM 312 and the RAM 313 may be individually configured as one chip. The same applies to CPUs of other control devices.

  The RAM 313 is configured to retain data by supplying data storage holding power from the power supply and launch control board 321 provided in the power supply and launch control device 243 even after the pachinko machine 10 is powered off.

  The CPU 311 is provided with an input port and an output port. Connected to the input side of the CPU 311 are a power failure monitoring circuit 303 provided on the main control board 301, a payout control board 322 provided on the payout control device 242, and a switch group (not shown). In this case, a power supply and launch control board 321 is connected to the power failure monitoring circuit 303, and power is supplied to the CPU 311 (main control circuit 302) via the power failure monitoring circuit 303.

  On the other hand, a power failure monitoring circuit 303, a payout control board 322 and a relay terminal board 323 are connected to the output side of the CPU 311. Various commands such as a prize ball command are output to the payout control board 322. Various commands and the like are output from the main control circuit 302 to the sound lamp control board 324 provided in the sound lamp control device 143 via the relay terminal plate 323.

  The power failure monitoring circuit 303 relays between the main control circuit 302 and the power source and launch control board 321, and monitors a DC stable voltage of 24 volts that is the maximum voltage output from the power source and launch control board 321. When this voltage becomes less than 22 volts, it is determined that the power supply has been cut off and a power failure signal is transmitted to the main control circuit 302. In the main control circuit 302, by confirming the input of the power failure signal, a power failure process (power failure process) to be described later is executed based on the confirmation result.

  The payout control board 322 performs payout control of prize balls and rental balls by the payout device 224. The CPU 331 that is an arithmetic unit includes a ROM 332 that stores a control program executed by the CPU 331, fixed value data, and the like, and a RAM 333 that is used as a work memory or the like.

  Similar to the RAM 313 of the main control circuit 302, the RAM 333 of the payout control board 322 is configured to retain data by supplying the data storage holding power from the power supply and the launch control board 321 even after the power of the pachinko machine 10 is shut off. It has become.

  The CPU 331 of the payout control board 322 is provided with an input / output port. A main control circuit 302, a power and launch control board 321, and a back pack board 229 are connected to the input side of the CPU 331. Further, the main control circuit 302 and the back pack substrate 229 are connected to the output side of the CPU 331.

  The power source and launch control board 321 includes a power source unit 321a and a launch control unit 321b. The power supply unit 321a is connected to, for example, a commercial power supply (external power supply) in a game hall or the like. Then, based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control circuit 302, the payout control board 322, etc., and the generated operating power is indicated by a double line arrow. This is supplied to the main control circuit 302 and the payout control board 322 through the path. As its outline, the power supply unit 321a takes in the AC 24 volt power supplied via the backpack connection board 229, and generates + 12V power for driving various switches, motors, etc., + 5V power for logic, and the like. The + 12V power and + 5V power are supplied to the main control circuit 302, the payout control board 322, and the like.

  The launch control unit 321b is responsible for launch control of the game ball launching mechanism 110 in accordance with the operation of the game ball launch handle 41 by the player, and the game ball launching mechanism 110 is driven when predetermined launch conditions are met. The

  The power supply and launch control board 321 is equipped with a data storage holding capacitor 321c as a power supply means for power interruption. A power storage unit 321a is connected to the data storage holding capacitor 321c, and is charged when the power of the pachinko machine 10 is in an ON state (when power is supplied from an external power source). In addition, the data storage holding capacitor 321c is connected to the VBB terminal of the CPU 311 in the main control circuit 302. When the power of the pachinko machine 10 is in an OFF state or when a power failure occurs in a commercial power source, the power storage state (from an external power source) In this case, the data storage holding capacitor 321c is discharged and the data storage holding power is supplied to the RAM 313. Therefore, even in such a situation, while the data storage holding power is supplied from the data storage holding capacitor 321c, the data stored in the RAM 313 is held without being erased.

  Incidentally, the electric power charged in the data storage / holding capacitor 321c is used for storing and holding data in the RAM 313 and other RAMs of the main control circuit 302, and is not used for operating devices such as an electric actuator. The capacity of the data storage capacitor 321c is relatively large, and the information stored in the RAM 313 before the power is shut off is held within a predetermined period (for example, 1 day or 2 days). Further, the power supply means for power interruption is not limited to the data storage holding capacitor, and may be a battery or a non-rechargeable battery. In the case of a non-rechargeable battery, it is not necessary to store power in the power supply means for power interruption when the power of the pachinko machine 10 is ON, but it is necessary to replace it periodically.

  Further, the power and launch control board 321 is provided with a power failure processing capacitor different from the data storage holding capacitor 321c. In the power source and launch control board 321, even after the DC stable 24 volt power source becomes less than 22 volts, by discharging from the power failure processing capacitor, a time sufficient for execution of the power failure processing described later, The output of 5 volts, which is a drive power source for the control system, is configured to maintain a normal value. Thereby, the main control circuit 302 and the like can normally execute and complete the power failure process.

  The sound lamp control board 324 controls the various lamp units 23 to 25, the speaker unit 26, and the display control device 325. The CPU 341 that is an arithmetic unit includes a ROM 342 that stores a control program executed by the CPU 341, fixed value data, and the like, and a RAM 343 that is used as a work memory or the like.

  The CPU 341 of the sound lamp control board 324 is provided with an input / output port. The main control circuit 302 is connected to the input side of the CPU 341 by relaying to the relay terminal plate 323. Based on various commands output from the main control circuit 302, various lamp units 23 to 25, the speaker unit 26, and The display control device 325 is controlled. The display control device 325 controls the symbol display device 91 based on a display command input from the sound lamp control board 324.

  The detection device 265 and the operation mechanism 275 are connected to the main control board 301 via the relay board 286. The detection device 265 and the operation mechanism 275 operate by receiving power supply from the main control board 301. In the detection device 265, a signal (light reception signal) generated by receiving power supply is fed back to the main control board 301.

  Next, each control process executed by the CPU 311 of the main controller 162 will be described with reference to the flowcharts of FIGS. The processing of the CPU 311 is roughly divided into main processing that is started when the power is turned on, timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and a power failure signal to the NMI terminal (non-maskable terminal). For convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  FIG. 20 shows an NMI interrupt process, which is executed when the power of the pachinko machine 10 is shut down due to the occurrence of a power failure or the like. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, a power failure signal is output from the power monitoring circuit 303 to the NMI terminal of the CPU 311 and the CPU 311 interrupts the control being executed and starts the NMI interrupt processing. . In the NMI interrupt processing, the power failure flag is set in the power failure flag storage area provided in the RAM 313 in step S101, and this processing is terminated. Thereafter, when it is confirmed that the power failure flag is set in the normal processing described later, the power failure processing is executed.

  Next, timer interrupt processing will be described with reference to the flowchart of FIG.

  In step S201, signal reading processing from various switches and the payout control board 322 is executed. Thereafter, a front door frame opening monitoring process is executed in step S202, and a main body frame opening monitoring process is executed in step S203. In the front door frame opening monitoring process, based on the input signal from the first monitoring device 250, a process related to monitoring the opening of the front door frame 14 in a situation where power is supplied from an external power source is executed. Further, in the main body frame opening monitoring process, processing related to monitoring of opening of the gaming machine main part 12 in a situation where power is supplied from an external power source is executed based on an input signal from the second monitoring device 290. Thereafter, a start winning process is executed in step S204. Details of each monitoring process will be described later.

  In the start winning process, it is determined whether or not the game ball has won the operating port 84 based on the signal input from the operating port switch 154. And when a game ball has won a prize in the operation slot 84, the winning is a big hit with respect to the prize, provided that the number of reserved balls in the first specific lamp section 93 and the symbol display device 91 is less than the upper limit value. A process of storing in the RAM 313 a counter value serving as an index as to whether or not to generate is executed. If the counter value is a value corresponding to the occurrence of the big win, the big win will occur in the game times corresponding to the winning. That is, in the start winning process, a lottery function (transition determination means) for transitioning to a special gaming state such as a big win is performed.

  After the start winning process, the CPU 311 once ends this timer interrupt process. In the timer interrupt process, a process of updating a counter value serving as an index as to whether or not to generate a jackpot may be executed.

  Next, the main process that is started upon reset at power-on will be described with reference to the flowchart of FIG.

  First, in step S301, an initial setting process associated with power-on is executed. Specifically, in order to wait for the slave control board (such as the payout control board 322) to become operable, a wait process is executed for about 1 second, for example. In the subsequent step S302, access to the RAM 313 is permitted.

  Thereafter, in step S303, it is determined whether or not the RAM erase switch 247 provided in the power supply and launch control device 243 is turned on. In subsequent step S304, whether or not the power failure flag is stored in the power failure flag storage buffer of the RAM 313 is determined. Determine. In step S305, a RAM determination value is calculated. In subsequent step S306, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the stored data. The RAM determination value is a checksum value at a work area address of the RAM 313, for example. It is also possible to determine the validity of the stored data based on whether or not the keywords written in a predetermined area of the RAM 313 are correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in the hall, the power is turned on while pressing the RAM erase switch 247. Therefore, if the RAM erase switch 247 is pressed, the process proceeds to steps S307 to S310. Similarly, when the information on occurrence of power shutdown is not set, or when an abnormality of data stored and held is confirmed by the RAM determination value (checksum value or the like), the process proceeds to steps S307 to S310.

  In step S307, an audio lamp initialization command is output to the audio lamp controller 143. Thereby, the initialization of RAM data, the abnormality of the data stored and held by the RAM judgment value, etc. are notified. In the subsequent step S308, a payout initialization command or the like is output in order to initialize the payout control board 322 or the like as the slave control board. In subsequent step S309, the used area of the RAM 313 is cleared to 0, and in step S310, initialization processing of the RAM 313 is executed. Thereafter, the process proceeds to normal processing to be described later through steps S314 to S318 and S311.

  On the other hand, if the RAM erase switch 247 has not been pressed, the process proceeds to step S312 on condition that the power failure flag is stored and that the RAM determination value (checksum value, etc.) is normal. In step S312, the power failure flag stored in the power failure flag storage buffer is cleared. In the subsequent step S313, a power recovery command for returning the slave control board to the gaming state before power-off is output. Thereafter, the power recovery opening monitoring process in steps S314 to S317 is executed. The power recovery opening monitoring process will be described later in detail. Thereafter, interrupt permission is set in step S311, and the process proceeds to normal processing described later. Thereby, it returns to the state before power-off.

  Next, normal processing will be described using the flowchart of FIG. In this normal process, the main process of the game is executed.

  In the normal process, in step S401, output data such as a command updated in the previous process is output to each control board on the slave side. Specifically, the command set in the command setting process described later is output to the payout control board 322 and the like. In addition, a stop symbol command, a variation mode command, and the like are output to the voice lamp control device 143 when the symbol display device 91 displays the variation of the first symbol.

  In a subsequent step S402, a first specific lamp unit control process for switching the color displayed on the first specific lamp unit 93 is executed. In the first specific lamp unit control process, jackpot determination, on / off control of a light source switch of an LED lamp disposed in the first specific lamp unit 93, and the like are performed. Then, in the first specific lamp control process, when it is determined that the jackpot is generated based on the counter value stored in the start winning process, the gaming state is shifted to the jackpot state. That is, in the first specific lamp control process, a function for shifting to the special gaming state (transition means) is performed. In the first specific lamp unit control process, the symbol display setting by the symbol display device 91 is also performed.

  After the first specific lamp unit control process, a special winning opening opening / closing process is executed in step S403. In the big prize opening / closing process, the big prize opening of the variable prize winning device 83 is opened or closed in the case of the big hit state. That is, it is determined whether the big winning opening is opened for each round of the big hit state, and whether the maximum opening time of the big winning opening has elapsed or whether a predetermined number of game balls have been won in the big winning opening. The determination as to whether or not the prescribed number has been won is made by confirming the above-described counter for the big prize opening. When either of these conditions is satisfied, the special winning opening is closed. In other words, the special game state progression function (progress means) is performed in the special prize opening / closing process.

  Thereafter, in step S404, a second specific lamp unit control process for switching the color displayed on the second specific lamp unit 94 is executed. In the second specific lamp control process, the switching of the display color in the second specific lamp unit 94 is started on condition that the number of gate-reserved balls is 1 or more. At this time, the display color switching time is also set. When the electric accessory attached to the operation port 84 is opened for a predetermined time, a stop display of a predetermined color is performed on the second specific lamp unit 94.

  After step S404, a game ball launch control process is executed in step S405. In the game ball launch control process, the game ball launch mechanism 110 is once per predetermined period (for example, 0.6 sec) on condition that a launch permission signal is input from the launch control unit 321b of the power source and launch control board 321. The solenoid 111 is excited. Thereby, the game ball on the launch rail 112 is launched toward the game area. Incidentally, the launch permission signal is input to an input port other than the input port 311 in the CPU 311 and it is confirmed whether or not there is a launch permission signal at the input port in the game ball launch control process.

  In a succeeding step S406, it is determined whether or not a power failure flag is stored in a power failure flag storage buffer provided in the RAM 313. If the power failure flag is not stored, the last process of the plurality of processes that are repeatedly executed is completed, so whether or not the execution timing of the next normal process is reached in step S407, that is, the previous normal process It is determined whether a predetermined time (4 msec in this embodiment) has elapsed since the start of the process. If the predetermined time has not elapsed, the process returns to step S406, and if the predetermined time has elapsed, the process returns to step S401.

  On the other hand, if the power failure flag is stored in step S406, it means that the power supply has been cut off. Therefore, the power failure processing after step S408 is executed. That is, in step S408, the generation of timer interrupt processing is prohibited. In the subsequent step S409, a power interruption update process is executed. In the power interruption update process, various information such as a gaming state is stored in the RAM 313. Thereafter, in step S410, a power failure command indicating that the power supply has been shut off is output to another control board. In step S411, the RAM determination value is calculated and stored. After the access to the RAM 313 is prohibited in step S412, the infinite loop is continued until the power supply is completely shut down and the process cannot be executed. Even after the power supply is completely shut down, the data storage holding power is supplied from the power supply and data storage holding capacitor 321c of the launch control board 321. Therefore, the information stored in the RAM 313 before the power shutdown is kept as it is. In a predetermined period (for example, 1 day or 2 days).

  Next, an electrical configuration relating to monitoring of opening of the front door frame 14 and the gaming machine main part 12 will be described based on the block diagram of FIG.

  A first monitoring device 250 and a second monitoring device 290 are electrically connected to the main control device 162 (specifically, the main control board 301). The CPU 311 of the main controller 162 grasps the detection states of the monitoring devices 250 and 290 based on signals input from the first monitoring device 250 and the second monitoring device 290. That is, the CPU 311 determines whether or not the front door frame 14 and the gaming machine main body 12 are opened during power-on and power-off based on the detection state information input from the monitoring devices 250 and 290. Then, the specific output process is executed based on the determination result.

  Next, regarding the opening of the front door frame 14 and the gaming machine main part 12, each control process executed by the CPU 311 of the main control device 162 will be described.

  First, the process executed in the timer interrupt process (FIG. 21) will be described.

  In the signal reading process in step S201 in the timer interrupt process, signals (light reception signals) input from the first monitoring device 250 and the second monitoring device 290 are read. The read signal information is stored and held in a register of the CPU 311. In this case, the CPU 311 is provided with at least a first register and a second register, signal information of the first monitoring device 250 is stored and held in the first register, and signal information of the second monitoring device 290 is stored in the first register. It is stored and held in two registers. The same applies to the following description regarding the registers of the CPU 311. In the subsequent step S202, a front door frame opening monitoring process is executed as a monitoring process of the front door frame 14 via the first monitoring device 250 in a state where power is supplied from an external power source.

  Here, the front door frame opening monitoring process will be described with reference to the flowchart of FIG.

  In the front door frame opening monitoring process, a comparison process is first executed in step S501. In the comparison process, the detection state information (light reception signal) stored in the register of the CPU 311 in the signal reading process is compared with the determination reference value stored in the ROM 312. In subsequent step S502, it is determined whether or not the value of the signal compared in the comparison process exceeds the determination reference value. As a result, if the value of the signal is equal to or greater than the determination reference value, the front door frame opening monitoring process is terminated as it is.

  On the other hand, when the value of the signal is smaller than the determination reference value, it means that the front door frame 14 is opened with respect to the main body frame 13. Thus, when the value of the signal is less than the determination reference value, in order to notify that the front door frame 14 is opened to the main body frame 13 in a situation where power is supplied from the external power source, In step S503, a normal time notification process is executed.

  In the normal notification process, a normal notification command is set. The set normal time notification command is output to the sound lamp control device 143 in the external output process of the normal process (FIG. 23). In the sound lamp control device 143, a notification sound is output from the speaker unit 26, the error display lamp unit 24 is turned on, and the symbol display device 91 performs notification display. The audio lamp control device 143 stops the various notifications after continuing the various notifications for a predetermined notification time (notification period). As this notification time, for example, 10 sec may be considered.

  In the normal notification process, a normal notification signal is output to the hall computer provided in the game hall via the external terminal board 213. In this case, in the hall computer, processing for storing identification information such as the date and time when the normal-time notification signal is input from the pachinko machine 10 and the machine number of the pachinko machine 10 as a history, and pachinko machines targeted at the surveillance cameras provided in the game hall Processing such as turning to the machine 10 is executed.

  In a situation where power is supplied from an external power source, if the above-described normal notification process is executed not at the timing when the front door frame 14 is closed but at the timing when the front door frame 14 is opened. It is possible to let the manager of the game hall deal with unauthorized opening of the front door frame 14.

  The normal time notification process is not limited to the above-described one, and only one of the normal time notification command and the normal time notification signal may be output. Further, as a process based on the output of the normal notification command, only a part of the output of the notification sound from the speaker unit 26, the lighting of the error display lamp unit 24, or the notification display on the symbol display device 91 is executed. It is good.

  After executing the normal time notification process in step S503, the front door frame opening monitoring process is terminated.

  Returning to the description of the timer interrupt process (FIG. 21), after executing the front door frame opening monitoring process in step S202, the second monitoring apparatus in a state where power is supplied from the external power source in step S203. A main body frame opening monitoring process is executed as a monitoring process of the gaming machine main unit 12 via 290.

  In the body frame opening monitoring process, when the information (light reception signal) of the detection state of the second monitoring device 290 grasped by the signal reading process is smaller than the determination reference value stored in the ROM 312, the normal time notification The processing is executed and the detection status information is updated. Since this specific processing configuration is the same as the front door frame opening monitoring processing, description thereof is omitted here.

  Note that the normal-time notification command or the normal-time notification signal may have different information forms in the normal-time notification processing in the front door frame opening monitoring processing and the normal-time notification processing in the main body frame opening monitoring processing. In this case, the notification mode can be made different between the pachinko machine 10 itself or the hall computer depending on whether the front door frame 14 is opened or the gaming machine main part 12 is opened.

  After executing the body frame opening monitoring process in step S203, the timer interruption process is terminated after the start winning process is executed in step S204. The start winning process is as described above.

  Next, processing executed in the main processing (FIG. 22) will be described.

  In the main process, for each of the monitoring devices 250 and 290, the power recovery opening monitoring process in steps S314 to S318 is executed.

  In the power recovery opening monitoring process, first, a detection state grasping process is executed in step S314. In the detection state grasping process, the signals input from the first monitoring device 250 and the second monitoring device 290 are read in the same manner as the signal reading process in step S201, and the information of the read signals is stored in the register of the CPU 311. Retained.

  In subsequent step S315, a comparison process is executed. In the comparison process, the signal value of the first monitoring device 250 stored in the register of the CPU 311 in the detection state grasping process is compared with the determination reference value stored in the ROM 312. In the comparison process, the signal value of the second monitoring device 290 stored in the register of the CPU 311 in the detection state grasping process is compared with the determination reference value stored in the ROM 312.

  In subsequent step S316, it is determined whether or not the value of the signal of the first monitoring device 250 compared in the comparison process exceeds the determination reference value, and the value of the signal of the second monitoring device 290 exceeds the determination reference value. It is determined whether or not. As a result, if both are equal to or greater than the determination reference value, interrupt permission is set in step S311, and the process proceeds to normal processing. If either one is smaller than the determination reference value, it means that the front door frame 14 or the gaming machine main part 12 is opened during the power-off, and the process proceeds to step S317.

  In step S317, a power recovery notification process is executed. In the power recovery notification process, a power recovery notification command is output to the sound lamp control device 143. Thereby, the output of the notification sound from the speaker unit 26, the lighting of the error display lamp unit 24, and the notification display on the symbol display device 91 are performed. However, these notification modes are different from the notification mode based on the normal-time notification command. In addition, the sound lamp control device 143 continues various notifications until a notification canceling operation such as opening / closing the gaming machine main part 12 or the front door frame 14 is performed. That is, not only the notification mode but also the notification cancellation mode differs between the normal time and the power recovery time. However, the present invention is not limited to this, and the notification mode and the notification release mode may be the same during normal operation and during power recovery.

  In the power recovery notification process, a power recovery notification signal is output to the hall computer provided in the game hall via the external terminal board 213. In this case, the hall computer is intended for processing of storing identification information such as the date and time when the power recovery notification signal is input from the pachinko machine 10 and the machine number of the pachinko machine 10 as a history, and the monitoring camera provided in the game hall. Processing such as turning to the pachinko machine 10 is executed.

  When the power recovery notification process is executed, if the front door frame 14 or the gaming machine main part 12 is opened while the power is shut off, the management of the gaming hall or the like is notified. If it is illegally open, it can be dealt with.

  In the power recovery notification process, when the front door frame 14 is opened and when the gaming machine main body 12 is opened, a power failure notification command or a power release detection signal is detected. The information form may be different. In this case, the notification mode may be different in the pachinko machine 10 itself or the hall computer depending on whether the front door frame 14 is opened while the power is shut off or the gaming machine main part 12 is opened while the power is shut off. It is possible to appropriately deal with the game hall manager or the like. In addition, the power recovery notification process is not limited to the above, and only one of the power recovery notification command and the power recovery notification signal may be output. Further, as a process based on the output of the power recovery notification command, only a part of the notification sound output from the speaker unit 26, the error display lamp unit 24 lighting, or the notification display on the symbol display device 91 is executed. It is good also as a structure.

  After the power recovery notification process is executed in step S317, the interrupt permission is set in step S311 and the process proceeds to the normal process.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  A first monitoring device 250 for monitoring the open state of the front door frame 14 is provided. The first monitoring device 250 can detect that the front door frame 14 is opened and can notify the error using the error display lamp unit 24 or the like. Thereby, the injustice performed with respect to the game board 81 (game area | region) can be suppressed.

  The first monitoring device 250 realizes opening detection of the front door frame 14 at the time of power supply and detection of opening of the front door frame 14 at the time of power supply interruption. Thereby, it is possible to improve the fraud suppression effect while suppressing complication of the configuration.

  In the present embodiment, the fact that the front door frame 14 is illegally opened from the structural side is particularly preserved. Compared with the configuration in which the opening history of the front door frame 14 is stored from the electrical side, a power source (for example, a battery or the like) for moving the electrical device in a state where the power supply is cut off is not required. Therefore, fraud suppression effect can be enhanced while contributing to energy saving.

  The dead weight of the shielding part 277b and the magnetic force of the solenoid 276 are used for the movement of the shielding part 277b between the first position and the second position. In this way, by using the falling weight of the shielding part 277b, the movement between the positions of the shielding part 277b is realized without using a biasing member or the like. Thereby, it contributes to simplification of the structure for making the shielding part 277b reciprocate.

  The light emitting element 266 and the light receiving element 267 are gathered on the main body frame 13 side, and the light reflecting member 274 is disposed on the front door frame 14 so that light from the light emitting element 266 is delivered to the light receiving element 267. In this way, the elements 266 and 267 that require electrical connection are concentrated on the main body frame 13 side, thereby simplifying the handling of the harness and the like. Further, the configuration necessary for detecting the opening of the front door frame 13 (the first monitoring device 250 and the like) is mainly arranged on the main body frame 13 side, thereby suppressing an increase in the weight of the front door frame 13. Thereby, workability | operativity at the time of opening and closing of the front door frame 13 is ensured.

  Further, by using the light reflecting member 274, a light passage route can be set long. In the configuration in which the light from the light emitting element 266 is reflected by the light reflecting member 274 and reaches the light receiving element 267, the position where the reflected light from the light reflecting member 274 reaches is the incident angle to the light reflecting member 274 and the passage of light. It depends on the length of the path. Even when the opening angle of the front door frame 14 is small, that is, when the change in the incident angle to the light reflecting member 274 is small, the change in the arrival position of the reflected light is greatly increased by setting the light passage route long. can do. Thereby, arrival of the reflected light to the light receiving element 267 can be suppressed, and the accuracy of detecting the opening of the front door frame 14 can be improved. That is, even when the opening angle of the front door frame 14 is small, it is possible to suitably detect the opening state. For example, it is possible to contribute to the suppression of fraudulent acts performed with the front door frame 14 slightly opened.

  A prism was used as the light reflecting member 274, and the direction of the central axis of the light emitting element 266 and the light receiving element 267 was set to the front-rear direction. When the front door frame 14 is rotated, if the amount of rotation is small, the displacement component from the initial position of the rotation tip portion tends to be larger in the front-rear direction than in the left-right direction. That is, in the state where the front door frame 14 is closed, the positional relationship between the light reflecting member 274 and the elements 266 and 267 is hardly changed in the left-right direction. For this reason, even if the position of the front door frame 14 in the closed state slightly varies in the rotation direction, the path of light reaching the light receiving element 267 from the light emitting element 266 via the light reflecting member 274 is It is easy to be secured. In other words, a decrease in open detection accuracy due to the positional variation of the front door frame 14 is suppressed.

  As described above, by providing the light reflecting member 274 and the elements 266 and 267, the displacement of the relative position in the left-right direction is accurately detected while allowing the displacement of the relative position in the front-rear direction of the pachinko machine 10. be able to. Therefore, it is possible to improve the detection accuracy when the front door frame 14 is opened while suppressing the malfunction of the opening detection in the state where the front door frame 14 is closed.

  In this Embodiment, it was set as the structure which controls or accept | permits the switching of the position of the shielding part 277b by utilizing the displacement of the relative position of the main body frame 13 and the front door frame 14. Specifically, the projection 14b of the front door frame 14 is separated from the path of the shielding part 277b, so that the movement of the shielding part 277b between the first position and the second position is possible. When the opening angle of the front door frame 14 is the same, the amount of displacement on the rotating distal end side tends to be larger than the amount of displacement on the rotating proximal end side. By disposing the first monitoring device 250 on the rotating front end side of the front door frame 14, it is easy to ensure the amount of movement of the protrusion 14b even when the front door frame 14 is opened small. Thereby, it is possible to easily secure the opening detection function of the first monitoring device 250 regardless of the degree of opening of the front door frame 14.

  Only the light receiving element 267 is covered by the shielding portion 277b. Assuming a case in which both the elements 266 and 267 are covered, there is a possibility that the light from the light emitting element 266 is reflected by the shielding part 277b and reaches the light receiving element 267 because the position of the shielding part 277b varies. In such a case, there may be a disadvantage that the front door frame 14 or the gaming machine main part 12 cannot detect the opening fact at the time of power interruption. However, by covering only the light receiving element 267 as described above, it is possible to suppress reflection of light at the shielding portion 277b and contribute to avoiding erroneous detection.

  In the state in which the opening of the gaming machine main part 12 or the front door frame 14 at the time of power interruption is detected, the detection state is reset by opening and closing the target in which the opening is detected. The gaming machine main part 12 and the front door frame 14 can be opened by a predetermined key operation. For this reason, the inconvenience that the detection state is illegally reset can be avoided.

  When the front door frame 14 is opened, until the rotation angle of the front door frame 14 reaches a predetermined angle, the front surface of the front door frame 14 is hardly visible by the opening flange 13a of the main body frame 13. The timing at which the movement restriction of the shielding portion 277b by the protrusion 14b is released is set earlier than the timing at which the first monitoring device 250 becomes visible. For this reason, even if an unauthorized tool is inserted from the boundary portion between the main body frame 13 and the front door frame 14 and the movement of the shielding portion 277b is prevented by the unauthorized tool, After 277b is moved. For this reason, it is possible to make an illegal act such as intentionally hindering the movement of the shielding part 277b difficult.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the first monitoring device 250 for monitoring the opening of the gaming machine main part 12 with respect to the outer frame 11 and the second monitoring device 290 for monitoring the opening of the front door frame 14 with respect to the main body frame 13 are provided. However, it is not always necessary to provide both, and only one of them may be provided. It is also possible to provide a backpack monitoring device that monitors the opening of the backpack unit 15 with respect to the main body frame 13.

  (B) In the above embodiment, the monitoring devices 250 and 290 are arranged in the main body frame 13, but this is changed, the first monitoring device 250 is arranged in the front door frame 14, and the second monitoring device is installed in the outer frame. 11 can also be arranged. It is also possible to unite both monitoring devices 250 and 290 and arrange them on the main body frame 13. Thereby, the site | part which should be confirmed in the case of a maintenance etc. can be reduced, and it can contribute to the improvement of work efficiency.

  (C) In the above embodiment, the light reflecting member 274 is configured by a prism. However, the light reflecting member 274 may be modified and configured by a mirror such as a plane mirror. For example, when only one plane mirror is used, the center axes of the light emitting element 266 and the light receiving element 267 may intersect with each other on the back surface of the front door frame 14, and the plane mirror may be disposed at the intersecting position.

  (D) In the above embodiment, the light emitting element 266 and the light receiving element 267 are provided on the main body frame 13, and the light reflecting member 274 is provided on the front door frame 14. You may change this as follows. That is, as shown in FIG. 26A, the light emitting element 400 may be provided on one of the main body frame 13 and the front door frame 14, and the light receiving element 401 may be provided on the other. By arranging both elements 400 and 401 to face each other, light can be transferred between the elements 400 and 401. Thereby, the diffusion of light between both elements 400 and 401 can be suppressed, and the amount of light reaching the light receiving element 401 can be easily secured.

  (E) In the above embodiment, the operation shaft 277 of the solenoid 276 is in a contracted state when energized, and is in an extended state when the power is cut off. It is also possible to adopt a configuration as follows.

  (F) In the above-described embodiment, the central axis of the solenoid 276 is oriented in the vertical direction, but this can be changed as follows. That is, the central axis of the solenoid 276 may face the horizontal direction. However, in such a case, it is difficult to switch the position using the weight of the operation shaft 277. Therefore, it is preferable to provide an urging means for urging the operation shaft 277 in a direction opposite to the operation direction when the solenoid 276 is energized. For example, a coil spring may be used. When the solenoid 276 is excited, the operation shaft 277 can move against the urging force of the coil spring, so that switching between the first position and the second position is ensured.

  (G) In the above embodiment, the entire housing case body 251 has a light-transmitting configuration, but the entire housing case body 251 does not necessarily have to have a light transmitting property. It is sufficient that at least a range of the front plate portion 255 of the housing case body 251 facing both the elements 266 and 267 has light transmittance.

  (H) In the above-described embodiment, the open sensor is configured to detect the opening using the light sensors of the light emitting element 266 and the light receiving element 267, but a push sensor may be used instead of the light sensor. Hereinafter, a specific configuration using the push sensor will be described with reference to FIG. A switch 410 that is in contact with the shielding part 277b is provided at the lower limit position of the shielding part 277b. The switch 410 includes a base 411 to be attached to the housing case body 251 and a movable part 412 provided to be displaceable with respect to the base 411. The movable portion 412 is set so as to be displaceable in the same direction as the moving direction of the shielding portion 277b, and can be switched between two states: an extended position extending toward the shielding portion 277b and a contracted position. The contact portion 413 of the switch 410 with the shielding portion 277b is urged toward the extended position by an urging means (not shown) (for example, a coil spring). An abutting portion 413 that abuts against the shielding portion 277b is provided at the tip of the movable portion 412. When the shielding portion 277b moves to the second position, it comes into contact with the abutting portion 413. When the shielding part 277b hits the contact part 413 while the movable part 412 is in the extended position, the movable part 412 is pushed against the urging force of the urging means and is moved to the contracted position. For example, a configuration may be employed in which a predetermined signal is output to the relay board 286 when the switch 410 is contracted. By outputting the signal, it is possible to detect unauthorized opening of the front door frame 14 or the like when the power is cut off.

  (I) In the above-described embodiment, the first monitoring device 250 is provided on the rotating front end side of the front door frame 14 in the main body frame 13, but the position of the first monitoring device 250 is not limited to this. . For example, you may provide in the rotation base end side of the main body frame 13. FIG. Similarly, the arrangement position of the second monitoring device 290 is not limited to the lower part of the main body frame 13, and can be provided, for example, at the upper part of the main body frame 13.

  (J) In the above embodiment, the first monitoring device 250 is configured to have both the opening detection function at the time of power supply and the opening detection function at the time of power interruption. However, a separate monitoring device has each opening detection function. It is good also as a structure. Hereinafter, a specific example will be described with reference to FIG. FIG. 26 (c) is a schematic diagram showing an embodiment of the open monitoring device at the time of power interruption.

  The open monitoring device 420 includes a light emitting element 422 and a light receiving element 423 that are disposed to face each other inside the housing 421. A predetermined gap is provided between the elements 422 and 423, and the shielding part 424 can move through the gap. Light emitted from the light emitting element 422 reaches the light receiving element 423 directly without passing through the outside of the housing 421. In such a configuration, the opening detection function of the front door frame 14 in the power supply state is omitted, but the opening detection function of the front door frame 14 in the power cut-off state is secured. In such a case, the housing 421 does not need to be light transmissive, and the housing 421 is configured not to have light transmissive properties, which makes it difficult to illegally access the shielding unit 424 from the outside of the open monitoring device 420. Can be. Instead of arranging both elements 422 and 423 to face each other, a light reflecting member such as a mirror facing both elements 422 and 423 may be provided in parallel with the left and right or top and bottom. The above modification may be applied to the second monitoring device 290.

  (K) In the above embodiment, the monitoring devices 250 and 290 are connected to the main control device 162. However, the connection destination is not limited to the main control device 162. For example, it is possible to connect to the audio lamp control device 143 or the like.

  (L) It is possible to further include a position detecting device for the protrusion 14b. The position detection device detects whether or not the protrusion 14b is in a predetermined position when the front door frame 14 is closed. Thereby, the open fact retention function of the monitoring device 250 at the time of power interruption can be secured. Hereinafter, a specific configuration will be described with reference to FIG.

  A detection switch 430 is provided inside the housing 252. The detection switch 430 includes a base portion 431 to be attached to the lid case body 280 and a movable portion 432 provided to be displaceable with respect to the base portion 431. The movable portion 432 is set to be displaceable in the same direction as the insertion direction of the protrusion 14b. More specifically, the movable part 432 can be switched between two positions, an extended position and a contracted position. The detection switch 431 includes a biasing member (for example, a coil spring) (not shown), and the movable portion 432 is biased toward the extended position by the biasing member. An abutting portion 433 is provided at the distal end of the movable portion 432 so that the distal end portion of the protrusion 14b hits. When the front door frame 14 is closed, the tip end portion of the protrusion 14 b hits the contact portion 433. The movable portion 432 is pushed against the urging force of the urging member, and is moved from the extended position to the contracted position. For example, a predetermined signal may be output to the relay board 286 by switching the movable portion 432 to the contracted position. By outputting the signal, it is possible to detect unauthorized opening of the front door frame 14 or the like when the power is cut off. In the position detection device 430, an optical sensor or the like can be used instead of the switch.

  (M) In the above-described embodiment, the operation shaft 277 is pulled upward by exciting the solenoid 276, but this can be changed as follows. That is, it is possible to adopt a configuration in which the operating shaft is pulled downward by exciting the solenoid 276. For example, the solenoid 276 may be arranged upside down. In such a case, as means for moving the operating shaft 277 in a non-excited state, it is preferable to use a biasing force by a biasing member such as a spring instead of gravity.

  (N) In the above-described embodiment, the cylindrical portion 277a and the shielding portion 277b of the operation shaft 277 are integrally provided. However, they can be separated. For example, a rod-shaped intermediate body that is pivotally supported is provided, a shielding portion is provided on one side of the shaft-supported portion, and a contact portion that can contact the cylindrical portion of the operation shaft is provided on the other side. It is good to provide. When the operating shaft pushes the contact portion, the intermediate body rotates, and the shielding portion is displaced accordingly. Thereby, the position of the shielding part can be switched. In order to displace the shielding part when the operating shaft moves away from the contact part, the weight (that is, the weight) of the shielding part itself is used, or it is urged by a biasing member such as a spring. Good.

  (O) In the seventh embodiment, the solenoid 276 is excited to displace the operating shaft 277 as a plunger inserted through the solenoid 276. However, this may be changed as follows. Is possible. That is, instead of the solenoid type electromagnet having the plunger, it is possible to use an electromagnet having no plunger. For example, instead of the operating shaft 277, a shielding member such as an iron ball made of a magnetic material provided separately from the electromagnet is provided, and the shielding member itself is attracted to the electromagnet by exciting the electromagnet. Good. More specifically, a shielding member may be disposed below the magnetic force generating portion of the electromagnet. When the electromagnet is excited, the shielding member is lifted and drawn to the magnetic force generating portion. Thereby, switching of the position of a shielding member is realizable.

  (P) In the embodiment described above, the opening monitoring process of the main body frame 13 and the front door frame 14 is configured to be incorporated in the timer interrupt process and the main process. It is also possible to incorporate 14 open monitoring processes in the normal process.

  (Q) The present invention can be applied to other types of gaming machines different from the above embodiment. For example, the present invention can be applied to a ball game machine such as a pachinko machine, an arrangement ball machine, or a sparrow ball that uses a game ball as a game medium. Further, the present invention can be applied to a ball-use spinning machine (so-called parrot) that can use a game ball as a game medium and can play a game similar to a so-called slot machine.

  It is possible to arbitrarily combine the configurations in the different examples of (a) to (q) described in detail above.
