  The mirror member 114 is installed obliquely (tilted) with respect to the game board 51 so that the upper part is the back side and the lower part is the front side. Specifically, the mirror member 114 has a short plate shape, and the length dimension in the short direction is set to be the same as or slightly smaller than the width dimension of the opening 100 of the game board 51. Yes. Further, the length dimension of the mirror member 114 in the longitudinal direction is set so that the mirror member 114 can be hooked to the main body case 111 in a state where the mirror member 114 is inclined. The upper end portion is set so as to come into contact with the inner wall surface on the back side of the main body case 111 in a situation where the upper end portion is disposed in the corner portion on the near side.

  The mirror member 114 has an upper end fixed to the side plate on the back side of the main body case 111 and a lower end fixed to the side plate on the near side of the main body case 111. As a configuration for fixing the mirror member 114 to the main body case 111, for example, a step-shaped guide portion for positioning the mirror member 114 is provided on the side wall of the main body case 111, and the mirror member 114 is provided in the guide portion. The mirror member 114 is installed at a predetermined position and angle by mounting the end of the mirror. The inclination angle of the mirror member 114 with respect to the game board 51 is about 45 °. That is, the projecting portion is provided in a linear shape of about 45 ° from the rear to the front of the main body case 111. A 7-segment display device 112 is disposed behind the mirror member 114.

  Specifically, a housing recess 115 that is recessed rearward is formed in a portion of the main body case 111 opposite to the case opening 111a. The accommodation recess 115 is formed in the same manner as the case opening 111a, and the accommodation recess 115 forms an accommodation space S3 in which the 7-segment display device 112 can be accommodated. The 7-segment display device 112 is housed in the housing space S3 so as to fit into the housing recess 115, and is fixed with screws in this state. In this case, the transparent plate 101, the case opening 111a, the mirror member 114, and the 7-segment display device 112 are arranged side by side in the longitudinal direction of the gaming machine.

  The seven-segment display device 112 is a three-digit segment light-emitting display device having three number display units capable of displaying numbers from 0 to 9 as symbols (pictures), so that the number display unit is on the front side (ie, , So as to be on the mirror member 114 side. Each of the number display portions is composed of seven display segments. By selectively emitting light from these seven display segments, numbers from 0 to 9 are displayed. The display segment is configured by LEDs that can emit light in a single color or a plurality of colors. In addition, the light source of a display segment is not limited to LED, For example, an incandescent lamp may be used.

  Here, the mirror member 114 is formed so as to transmit and reflect a part of the irradiated light. Specifically, the mirror member 114 is a half mirror formed so that the reflectance and the transmittance are substantially the same. is there. An example of a configuration for realizing the above function will be briefly described. The mirror member 114 includes a transparent base plate having a predetermined thickness dimension, and a metal thin film deposited on the base plate. . The thickness of the metal thin film is set so that the transmittance is the same as the reflectance. Thereby, in the situation where the space on the back side of the mirror member 114 is dark, specifically, in the situation where the number is not displayed on the 7-segment display device 112, the 7-segment display device 112 cannot be visually recognized from the case opening 111a side. In addition to being difficult to view, when light is irradiated from the front side through the case opening 111a, it reflects like a mirror and displays the surrounding scenery. On the other hand, when light larger than the intensity of light incident through the case opening 111a is irradiated from the 7-segment display device 112 side, the light becomes visible from the case opening 111a side.

  Here, the pachinko machine 10 is generally installed indoors (in the game hall) with the case opening 111a opened in a direction intersecting with the illumination light, and the indoor is provided on the ceiling. It is brightened by lighting. The emission intensity of the 7-segment display device 112 is set to be sufficiently larger than the intensity of light incident from the case opening 111a in the above situation. Thereby, in the situation where the number is displayed on the 7-segment display device 112, the light related to the number display can be visually recognized from the case opening 111a side, and the number can be visually recognized.

  The configuration of the mirror member 114 is not limited to this, and for example, a mirror member made of a dielectric multilayer film may be used, or a configuration in which unevenness that diffracts light on the surface may be provided. Moreover, you may provide the protective film which protects a metal thin film. Thereby, the fall of the transmittance | permeability and reflectance by a metal thin film oxidizing can be suppressed.

  The mirror member 114 is a half mirror having substantially the same reflectance and transmittance. However, the mirror member 114 is not limited to this, and may be a mirror having different reflectance and transmittance. In short, what is called a beam splitter may be used.

  As shown in FIG. 6, the plasma discharge device 113 is disposed on the front side in the traveling direction X of the reflected light incident from the case opening 111 a side and reflected by the mirror member 114, specifically, above the mirror member 114.

As shown in FIG. 8A, the height dimension (length dimension in the axial direction) of the rubber ring 133 is set to be larger than that of the pedestal portion 132. One end of the rubber ring 133 is formed with a diameter increased in a direction orthogonal to the axial direction. When the rubber ring 133 is inserted into the pedestal portion 132 from the end opposite to the one end with the expanded diameter, the one end portion and the pedestal portion 132 come into contact with each other, and further insertion is restricted, and the rubber ring 133 is restricted. Is installed at this position. In this state, a part of the plasma lamp 120 is fitted into the rubber ring 133, so that the plasma lamp 120 is installed in a state insulated from the surroundings.

  Specifically, the plasma lamp 120 is made of transparent glass, and includes a spherical shell portion 141 and a cylindrical portion 142 formed so as to protrude outward from the spherical shell portion 141. The outer diameter of the spherical shell portion 141 is set larger than the outer diameter of the rubber ring 133, while the outer diameter of the cylindrical portion 142 is set to be the same as or slightly smaller than the inner diameter of the rubber ring 133. As shown in FIG. 8A, the plasma lamp 120 is installed by fitting the cylindrical part 142 into the rubber ring 133. In this case, the cylindrical portion 142 and the rubber ring 133 are in contact with each other, and the plasma lamp 120 is not in direct contact with the first housing member 122. The outer diameter of the spherical shell 141 is set smaller than the outer diameter of the pedestal 132.

  The spherical shell portion 141 and the cylindrical portion 142 are in communication with each other, and one sealed internal space 143 is formed. A discharge gas 144 made of a rare gas such as argon is sealed in the internal space 143 as a discharge gas. The discharge gas 144 is sealed at a pressure lower than the atmospheric pressure so that a discharge is easily generated when a voltage is applied. The plasma lamp 120 is provided with a discharge electrode 150 for applying a voltage to the discharge gas 144.

  Specifically, the discharge electrode 150 is formed in a rod shape, and its axis is coated with an insulator 151 except for the tip. Corresponding to the shape of the discharge electrode 150, the plasma lamp 120 is formed with an electrode recess 152 by being recessed from the center of the bottom of the cylindrical portion 142 toward the center of the spherical shell 141.

  The electrode recess 152 is formed in such a size that the discharge electrode 150 coated with an insulating material 151 can be inserted. The electrode recess 152 is formed so that the tip of the discharge electrode 150 is positioned at the center of the spherical shell 141, and specifically, the bottom 153 of the electrode recess 152 is positioned around the center of the spherical shell 141. Thus, the depth dimension of the electrode recess 152 is set. As a result, the discharge electrode 150 is inserted into the electrode recess 152 in a state where the tip thereof is disposed at the center of the spherical shell 141.

  In this configuration, when a high-frequency AC voltage is applied to the discharge electrode 150, the tip of the discharge electrode 150 (the bottom 153 in the electrode recess 152 and the inner peripheral surface on the bottom 153 side) and the spherical shell 141, a high-frequency electric field is generated. The electric field causes the particles of the discharge gas 144 to be accelerated and collide. At this time, the discharge gas 144 is ionized and enters a plasma state. Then, a path through which a current easily flows is formed in the internal space 143 due to the movement of the charged particles generated by the ionization, and a current flows along the path to cause discharge light emission. This path is called a discharge path. It can be said that the discharge path is a moving path of charged particles.

  The movement path of the charged particles is a direction along the direction in which the electric field is applied (between the tip of the discharge electrode 150 and the spherical shell 141) when viewed macroscopically. It is random because of randomness. Further, since the distal end portion of the discharge electrode 150 is disposed at the center of the spherical shell portion 141, the distance from the distal end portion of the discharge electrode 150 to the inner wall surface of the spherical shell portion 141 is constant regardless of the direction. In addition, there is almost no direction dependency of the strength of the electric field applied between the distal end portion of the discharge electrode 150 and the inner wall surface of the spherical shell portion 141. As a result, the discharge path, which is the movement path of the charged particles, fluctuates randomly with respect to the inner wall surface of the spherical shell 141 around the tip of the discharge electrode 150.

  Here, since the plasma lamp 120 is made of transparent glass, it is possible to prevent the discharge light emission from becoming difficult to be seen by the plasma lamp 120. Further, since glass is excellent in heat resistance, it is difficult to be deformed even when the plasma lamp 120 generates heat by discharge light emission. However, there is a problem that glass is easily broken by an external impact. On the other hand, as shown in FIGS. 7 and 8A, a cover member 161 that covers the plasma lamp 120 is provided.

  The cover member 161 is made of a transparent acrylic resin and is an insulator. The cover member 161 is formed so as to correspond to the shape of the plasma lamp 120, and includes a cover-side cylindrical portion 162 and a hemispherical shell portion 163 that is continuous with one end of the cover-side cylindrical portion 162. A housing space 164 is defined by the cover-side cylindrical portion 162 and the hemispherical shell portion 163. The accommodation space 164 is opened to the outside through an opening 165 formed on the other end side of the cover-side cylindrical portion 162.

  The accommodation space 164 is formed in a size that can accommodate the plasma lamp 120 and the pedestal portion 132, and the opening 165 is formed in a size that allows the pedestal portion 132 to enter. Specifically, the inner diameter of the cover-side cylindrical portion 162 is set to be the same as or slightly larger than the outer diameter of the pedestal portion 132. The inner diameter of the hemispherical shell portion 163 is set larger than the outer diameter of the spherical shell portion 141, and specifically, is set to be the same as the outer diameter of the pedestal portion 132. When the cover member 161 is moved so that the pedestal portion 132 and the plasma lamp 120 are accommodated in the accommodation space 164 via the opening 165, the first housing that constitutes the installation case 121 and the periphery of the opening 165 of the cover member 161. The member 122 abuts and further movement is restricted. Then, the cover member 161 is attached to the installation case 121 at that position.

  Specifically, with respect to the attachment, as shown in FIG. 8A, the pedestal portion 132 is formed with a pair of through holes 171 and 172 penetrating in a direction orthogonal to the axial direction. In the through holes 171 and 172, claw portions 173 and 174 that are formed upright from the installation case 121 are provided. The claw portions 173 and 174 have free ends at their ends, and can be elastically deformed when an external force is applied. The claw portions 173 and 174 protrude outward from the outer peripheral surface of the pedestal portion 132, and the protruding dimensions are set so as to increase toward the installation case 121 side.

  Locking openings 175 and 176 are formed in the cover member 161 so as to correspond to the claw portions 173 and 174. In a situation where the peripheral edge of the opening 165 of the cover member 161 and the first housing member 122 are in contact with each other, the claws 173 and 174 are in contact with the edges of the corresponding locking openings 175 and 176. The relative positional relationship of is set.

  According to this configuration, when the cover member 161 is moved in the attachment direction, the claw portions 173 and 174 come into contact with the cover member 161 from the original side in the movement direction of the cover member 161, It is elastically deformed in the direction of immersing in 172. When the locking openings 175 and 176 reach the claw parts 173 and 174, the claw parts 173 and 174 return to a natural state by a restoring force. As a result, as shown in FIG. 8A, the claw portions 173 and 174 abut against the edge portions of the corresponding locking openings 175 and 176 from the front side in the moving direction of the cover member 161, and the above movement Even if it is going to move the cover member 161 in the direction opposite to the direction, it is blocked by the contact. The cover member 161 is fixed to the installation case 121 by the engagement between the claw portions 173 and 174 and the edges of the locking openings 175 and 176.

  As shown in FIG. 7, a positioning convex portion 177 is provided on the outer peripheral surface of the pedestal portion 132, and a groove portion in which the convex portion 177 can enter the cover member 161 corresponding to the convex portion 177. 178 is formed. By attaching the cover member 161 so that the convex part 177 enters the groove part 178, the position of the cover member 161 in the circumferential direction with respect to the installation case 121 is determined, and at that time, the claw parts 173 and 174 and the locking opening part 175 are naturally selected. 176 is locked.

  Here, as already described, since the discharge light emission performed in the plasma lamp 120 is random, there is a problem that the brightness of the plasma lamp 120 as a whole is reduced. In particular, since the brightness of discharge light emission of the plasma lamp 120 is likely to be smaller than other light emitting elements such as LEDs, it is difficult for the player to visually recognize the light emission mode of discharge. On the other hand, in this embodiment, a conductive seal 180 as an auxiliary electrode is provided separately from the discharge electrode 150. The conductive seal 180 will be described in detail.

  The conductive seal 180 is made of a light-shielding metal (specifically, copper foil) and is formed in a substantially short shape. An adhesive is applied to the entire back surface of the conductive seal 180. The conductive seal 180 is attached to the outer peripheral surface of the cover member 161, specifically, the outer peripheral surface of the cover-side cylindrical portion 162 so as to surround the plasma lamp 120 around the axis of the discharge electrode 150. That is, the conductive seal 180 is not directly attached to the plasma lamp 120 but is attached to the cover member 161. For this reason, it is possible to avoid the inconvenience that the plasma lamp 120 is broken by directly attaching the conductive seal 180 to the plasma lamp 120, and the conductive seal 180 can be easily attached.

  In view of the fact that the conductive seal 180 is affixed to the cover-side cylindrical portion 162, the cover-side cylindrical portion 162 can be said to be an affixed portion to which the conductive seal 180 is affixed.

  The conductive seal 180 is electrically connected to the discharge power supply substrate 124 via the wiring 181. Specifically, a slit 182 into which the wiring 181 can be inserted is formed in the first housing member 122, and the wiring 181 is led out of the installation case 121 through the slit 182. The tip of the wiring 181 is soldered to the conductive seal 180.

  According to such a configuration, when the conductive seal 180 is grounded so that a potential difference from the discharge electrode 150 is generated in a state where a voltage is applied to the discharge electrode 150, the discharge that has been uniform until then is caused by electrostatic induction. Disturbances occur in the ease of current flow. Specifically, as shown in FIG. 8A, electrostatic induction is generated by grounding the conductive seal 180, and current easily flows between the distal end portion of the discharge electrode 150 and the conductive seal 180. The discharge path is easily concentrated between the inductive portion 183 positioned and the tip of the discharge electrode 150. In other words, an induction portion 183 having a larger potential difference with respect to the discharge electrode 150 than other portions is formed in a portion located between the discharge electrode 150 and the conductive seal 180, and the discharge electrode 150 and the induction portion are formed. The discharge between the discharge electrode 150 and the induction portion 183 is easily concentrated because the discharge between the discharge portion 183 and the other portion is more likely to occur.

  Here, since the conductive seal 180 is disposed around the axis of the discharge electrode 150, the guide portion 183 is formed over the circumferential direction of the spherical shell portion 141. Thus, the discharge path is easily formed in the direction intersecting the axial direction of the discharge electrode 150 with the discharge electrode 150 as the center.

  In addition, a conductive paint 191 is applied to the inner peripheral surface of the electrode recess 152 so that the discharge path is easily trapped in the induction portion 183. As shown in FIG. 8B, the conductive paint 191 is formed around the axis of the tip of the discharge electrode 150, specifically, the bottom 153 of the electrode recess 152 and the inner peripheral surface of the electrode recess 152. It is applied over a predetermined region continuous from the bottom 153. Steel wool 192 is provided between the conductive paint 191 and the tip of the discharge electrode 150 to electrically connect them. The steel wool 192 is sandwiched between the discharge electrode 150 and the electrode recess 152 and is in contact with both. In this case, since the steel wool 192 is a collection of linear iron threads in a cotton shape, the steel wool 192 is not in contact with the surface but is in contact with many points. That is, it can be said that the steel wool 192 is electrically connected to the discharge electrode 150 and the conductive paint 191 with multiple contacts. In this case, since the conductive paint 191 is applied to the inner peripheral surface of the electrode recess 152, the numerous contacts are formed around the axis of the discharge electrode 150.

  According to this configuration, when a voltage is applied to the discharge electrode 150, the voltage is applied to the conductive paint 191 via the contact point between the steel wool 192 and the conductive paint 191. Then, since the electric field is more likely to concentrate on the contact as compared with the configuration in which both are in contact with each other, discharge is easily performed with the contact as a base point. As a result, more discharge paths are likely to occur.

  Further, since the contact point is formed around the axis of the discharge electrode 150, the discharge is easily performed in a direction intersecting the axis direction of the discharge electrode 150. Thereby, the discharge path is easily trapped by the induction portion 183. Therefore, the induction effect by the conductive seal 180 is enhanced.

  Further, a large number of the contacts are formed around the axis of the discharge electrode 150, and a discharge path is easily formed with any one of the contacts as a base point. Thereby, the randomness of the discharge path can be improved within a range in which the discharge path is easily trapped by the induction unit 183. Therefore, the randomness of the discharge path within the induction range of the conductive seal 180 can be improved while ensuring the induction function by the conductive seal 180.

  That is, by providing the conductive seal 180, it is possible to consolidate the discharge paths, but there is a concern about a decrease in the randomness of the discharge paths. On the other hand, according to the present embodiment, by providing the conductive paint 191 and the steel wool 192, the randomness of the discharge path is improved within the induction range of the conductive seal 180. Thereby, the randomness of a discharge path | route can be ensured, consolidating a discharge path | route.

  Further, the bottom portion 153 of the electrode recess 152 is curved so that the base point of the discharge path is not limited to the corner portion. Thereby, it is suppressed that the base point of a discharge path is limited and the number of discharge paths decreases.

  The plasma discharge device 113 configured as described above is attached to the main body case 111 in a state where the plasma lamp 120 and the cover member 161 are accommodated in the accommodation space S1. In addition to FIG. 6, the structure concerning the said attachment and the aspect in which the plasma discharge apparatus 113 is visually recognized are demonstrated using FIG. FIG. 9 is an explanatory diagram for explaining the plasma discharge device 113 when the plasma discharge device 113 is viewed in the traveling direction X of the reflected light of the light incident from the case opening 111a side. FIG. 9 can be said to be a diagram showing a reflected image of the mirror member 114. For convenience of explanation, the wiring 181 is omitted in FIGS.

  As shown in FIGS. 6 and 9, the body case 111 is provided with an opening 201 corresponding to the shape of the cover member 161. As shown in FIG. 6 and the like, the opening 201 is formed to have a size that allows the cover member 161 to pass through. Specifically, the opening 201 has a circular shape that is the same as or slightly larger than the outer diameter of the cover member 161. In addition, it is formed smaller than the installation case 121 so that the installation case 121 cannot pass therethrough.

  According to this configuration, when the plasma discharge device 113 is inserted with the cover member 161 as the insertion destination side so that the cover member 161 enters the accommodation space S1 through the opening 201, the surface on the insertion destination side of the installation case 121 is the main body. The position of the plasma discharge device 113 is defined by contacting the case 111. The installation case 121 is fixed to the main body case 111 with screws at this position.

  Specifically, as shown in FIGS. 6 and 9, attachment portions 211 are provided at each corner portion on the insertion destination side in the installation case 121. The attachment portion 211 is formed so as to extend in a direction along the wall surface (surface on the insertion destination side) of the main body case 111, and is in contact with the outer wall surface of the main body case 111. The attachment portion 211 is provided with a fixing through hole 212, and a screw 213 is screwed into the fixing through hole 212, so that the plasma discharge device 113 is placed in the cover member 161 and the internal space 143 thereof. The arranged plasma lamp 120 is fixed to the main body case 111 in a state of being accommodated in the accommodation space S1. In this case, the plasma discharge device 113 is arranged at a position separated from the display control device and the sound lamp control device 71 arranged behind the accommodation space S3.

  When discharge light emission is performed by the plasma lamp 120 in a state where the plasma discharge device 113 is fixed, the discharge light emission reflects the mirror member 114 and the case opening 111a is provided as shown in FIG. Proceed toward the direction you are. Thereby, discharge light emission is visible through the case opening 111a. In this case, the opening 201 is blocked by the installation case 121, so that light from the outside does not enter the main body case 111 through the opening 201.

  In addition, since the 7-segment display device 112 is arranged behind the mirror member 114 and the tilt angle of the mirror member 114 is set to 45 degrees, it is incident from the 7-segment display device 112 side and transmitted through the mirror member 114. The transmitted light L1 and the reflected light L2 that is generated by the plasma lamp 120 of the plasma discharge device 113 and reflected by the mirror member 114 are in the same direction, and both pass through the case opening 111a and the transparent plate 101. It progresses toward the front of the game board 51. Thereby, the display mode of the 7-segment display device 112 and the plasma discharge device 113 can be visually recognized through the common display unit 61.

  The relative positional relationship between the numbers displayed on the mirror member 114 by the 7-segment display device 112 and the discharge light emission of the plasma lamp 120 is set. Specifically, the plasma discharge device 113 is disposed above the region where the number display portion of the 7-segment display device 112 is displayed on the mirror member 114. Thereby, when both display (light emission) is performed, both will overlap and will be visually recognized.

  In addition, although the plasma discharge apparatus 113 was arrange | positioned above the mirror member 114, it is not restricted to this, For example, you may arrange | position below the mirror member 114. FIG. In this case, the tilt of the mirror member 114 may be reversed so that the reflected light L2 travels toward the case opening 111a. In short, the relative positional relationship between the seven-segment display device 112, the plasma discharge device 113, and the mirror member 114 and the inclination angle of the mirror member 114 may be set so that the transmitted light L1 and the reflected light L2 are in the same direction. .

  Next, the light emission mode of the plasma discharge device 113 will be described. In the situation where the plasma discharge device 113 is fixed, it is incident from the axial direction of the discharge electrode 150 and the case opening 111a side and reflected by the mirror member 114. The traveling direction X of the reflected light coincides. For this reason, as shown in FIG. 9, the discharge electrode 150 is projected in the form of a dot at the center of the plasma lamp 120 on the mirror member 114, which is visually recognized by the player. In this case, the reflected image of the mirror member 114 (image visually recognized by the player) can be said to be an image seen from the traveling direction X, and can also be seen to be an image seen from the extension of the discharge electrode 150.

  Here, since the conductive seal 180 is affixed over the outer peripheral surface of the cover-side cylindrical portion 162, the guide portion 183 is formed along the circumferential direction of the spherical shell portion 141. As a result, as shown in FIG. 9, the mirror member 114 displays a mode in which discharge paths are formed radially around the discharge electrode 150, and the mode can be visually recognized. In this case, the component in the direction orthogonal to the axial direction of the discharge electrode 150 out of the components of the light emitted by the discharge light emission becomes large. Therefore, when the plasma discharge device 113 is viewed from the extension of the discharge electrode 150, Brightness is improved. Therefore, the brightness of the entire plasma lamp 120 is increased.

  The outer diameter of the cover-side cylindrical portion 162 is set to be constant without depending on the traveling direction X (the axial direction of the discharge electrode 150). As a result, the conductive seal 180 is less noticeable than the configuration in which the conductive seal 180 is attached to the hemispherical shell 163.

  That is, for example, when the conductive seal 180 is attached to the outer peripheral surface of the hemispherical shell portion 163 whose outer diameter depends on the traveling direction X, the conductive seal 180 is reflected in a ring shape on the reflected image of the mirror member 114. The conductive seal 180 is easily noticeable. In order to avoid such an inconvenience, it is conceivable to reduce the width dimension (length dimension in the short direction) of the conductive seal 180. However, if the width dimension is reduced, the induction function of the discharge path by the conductive seal 180 may be reduced due to the difficulty of forming the induction portion 183, and the conductive seal 180 is easily peeled off due to the reduction of the pasting area. There is a risk that.

  On the other hand, in the present embodiment, since the conductive seal 180 is attached to the outer peripheral surface of the cover-side cylindrical portion 162, when viewed from the traveling direction X (from the extension of the discharge electrode 150), As shown in FIG. 9, it looks like a line along the outer peripheral surface of the cover member 161. As a result, the conductive seal 180 is less noticeable. In this case, there is no apparent change even if the width dimension of the conductive seal 180 is increased. Therefore, the conductive seal 180 can be made inconspicuous while ensuring the width dimension of the conductive seal 180 so that the function of inducing the discharge path by the conductive seal 180 and the adhesion function of the conductive seal 180 are exhibited.

  As shown in FIG. 9, a pair of opening / closing shutters 221 as opening / closing means is provided between the mirror member 114 and the plasma discharge device 113. As shown in FIG. 6, the open / close shutter 221 is disposed on the original side in the traveling direction X with respect to the plasma discharge device 113, specifically, on the mirror member 114 side with respect to the plasma discharge device 113. The 7-segment display device 112 is disposed at a position where the transmitted light L1 from the side is not obstructed. This avoids the inconvenience that the open / close shutter 221 makes it difficult to see the display mode of the 7-segment display device 112.

  The opening / closing shutter 221 has a rectangular plate shape, and is arranged so that its plate surface is orthogonal to the traveling direction X, specifically, to be orthogonal to the surface of the game board 51. The length dimension of the opening / closing shutter 221 in the longitudinal direction (length dimension in the longitudinal direction of the gaming machine) is set to be substantially the same as the longitudinal dimension of the gaming machine in the longitudinal direction on the inner wall surface of the main body case 111. The opening / closing shutter 221 is formed so as not to be able to transmit light or difficult, and is specifically painted black. The open / close shutter 221 is configured to be switchable between an open state in which the plasma discharge device 113 is visible and a closed state in which the plasma discharge device 113 is invisible or difficult.

  Specifically, as shown in FIG. 6, the side surface in the front-rear direction of the gaming machine on the inner wall surface of the main body case 111 protrudes toward the side surfaces facing each other and extends along the left-right direction of the game board 51. First protrusions 222 and 223 and second protrusions 224 and 225 are provided. The first ridges 222 and 223 and the second ridges 224 and 225 are disposed to face each other. Since the first protrusions 222 and 223 and the second protrusions 224 and 225 have the same configuration, the first protrusions 222 and 223 will be described.

  The first protrusions 222 and 223 are formed at intervals in the traveling direction X. The interval is the same as or slightly larger than the thickness dimension of the opening / closing shutter 221. As a result, a first groove 226 into which a part of the opening / closing shutter 221 can enter is formed by the first protrusions 222 and 223. The first groove 226 extends in the front-rear direction. Similarly, the second groove 227 is formed in the second protrusions 224 and 225, and the first groove 226 and the second groove 227 are opposed to each other. The both ends of the opening / closing shutter 221 enter the grooves 226, 227 so that the opening / closing shutter 221 is movable in the front-rear direction.

  When the opening / closing shutter 221 is closed, the length of the opening / closing shutter 221 in the short direction (the length in the left-right direction of the gaming machine) is set larger than the diameter of the cover member 161. Further, the distance between the open / close shutters 221 when the open / close shutter 221 is opened is set to be larger than the diameter of the cover member 161. Thereby, as shown in FIG. 9, when the open / close shutter 221 is opened, the plasma discharge device 113 is visually recognized. On the other hand, when the open / close shutter 221 moves in the direction indicated by the two-dot chain line in FIG. 9 and the open / close shutter 221 is closed, the plasma discharge device 113 is not visually recognized.

  Note that the opening / closing shutter 221 is not limited to the above-described configuration, and may be configured by only one or three or more. Further, a rotary type may be used instead of the sliding door type. In short, the shape of the plasma lamp 120 is arbitrary as long as it can be switched between a state in which the plasma lamp 120 is hardly visible and a state in which the plasma lamp 120 is visible.

  Next, a display mode in the variable display unit 56 configured as described above will be described with reference to FIG. 10A shows a display mode of the 7-segment display device 112, and FIG. 10B shows a display mode of the plasma discharge device 113 when the 7-segment display device 112 and the open / close shutter 221 are closed. FIG. 10C is a diagram showing a state of being combined on the mirror member 114, and FIG. 10C is a view of combining the display mode of the plasma discharge device 113 on the mirror member 114 when the 7-segment display device 112 and the open / close shutter 221 are open. It is a figure which shows the state which carried out. 10B and 10C can be said to be display modes displayed on the display unit 61. FIG.

  As shown in FIG. 10A, the 7-segment display device 112 performs numerical emission display on the three numeric display units 231. When the opening / closing shutter 221 is in a closed state in a state where the number display unit 231 performs the light emission display of the number, as shown in FIG. The plasma lamp 120 is not visually recognized by the open / close shutter 221.

  Here, since the plasma lamp 120 is made of glass, the plasma lamp 120 reflects ambient light and reflects on the mirror member 114 even when the plasma lamp 120 does not emit light. It may be visually recognized by the player. On the other hand, according to the present embodiment, when the open / close shutter 221 is closed, almost all light from the plasma lamp 120 is absorbed by the open / close shutter 221. Thereby, the reflection is suppressed.

  On the other hand, when the open / close shutter 221 is in an open state in a state where the number display portion 231 of the 7-segment display device 112 is performing light emission display, as shown in FIG. 10C, the 7-segment display device The three numbers displayed at 112 are visually recognized, and the discharge emission of the plasma lamp 120 is visually recognized. In this case, both are overlapped and visually recognized.

  Here, the light emission mode of the plasma discharge device 113 is a mode in which the discharge path fluctuates, and is completely different from a normal light emission mode such as an LED. Further, it is difficult to reproduce the light emission mode even with an existing FPD such as a liquid crystal display device. Thereby, by making the light emission mode of the plasma discharge device 113 visible, a novel impression can be given to the player, and the player's attention can be increased. In particular, by overlapping the display mode of the 7-segment display device 112 and the light emission mode of the plasma discharge device 113 having a display mode different from that, it is possible to visually recognize a more innovative effect than the effect of visually recognizing both. it can.

<Electrical configuration>
Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG.

  An MPU 302 is mounted on the main control board 301 provided in the main control device 72. The MPU 302 is a ROM 303 that stores various control programs executed by the MPU 302 and fixed value data, and a memory for temporarily storing various data when the control program stored in the ROM 303 is executed. The RAM 304 is an element incorporating an interrupt circuit, a timer circuit, a data input / output circuit, various counter circuits as a random number generator, and the like. Note that a part of the functions of the MPU 302, such as the function of the ROM 303 and the function of the RAM 304, may be included as another element.

  The MPU 302 is provided with an input port and an output port. Connected to the input side of the MPU 302 are a power failure monitoring board 305 provided in the main control device 72, a payout control device 91, various winning detection sensors 311a to 311e, and the like. In this case, a power supply and launch control device 92 is connected to the power failure monitoring board 305, and power is supplied to the MPU 302 via the power failure monitoring board 305. In addition, as a part of the various winning detection sensors 311a to 311e, a plurality of payout-corresponding entrance portions (payout-corresponding entrance portions) such as the general payout port 52, the variable winning device 53, the operation port 54, and the through gate 55 are provided. Are detected, and the MPU 302 of the main control device 72 performs a winning determination (penetration determination) for each pitching section. In addition, the MPU 302 executes a jackpot generation lottery based on a winning at the operation port 54 and also executes a support generation lottery based on a winning at the through gate 55.

  Here, a configuration for performing various lotteries in the MPU 302 will be described.

  The MPU 302 uses lots of counter information in the game to perform jackpot occurrence lottery, setting the display of the main display unit 59, setting the symbol display of the 7-segment display device 112, and more specifically, as shown in FIG. As described above, when the jackpot random number counter C1 used for the jackpot occurrence lottery, the jackpot type counter C2 used when determining the jackpot type such as the probability variation jackpot result or the normal jackpot result, and the 7-segment display device 112 are changed. Reach random number counter C3 used for reach generation lottery, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, and variation type counter for determining variation display time in the main display unit 59 and the 7-segment display device 112 CS is used. Furthermore, the electric accessory release counter C4 used for the lottery to determine whether or not the electric accessory 54a of the operation port 54 is in the electric utility open state is used.

  Each of the counters C1 to C3, CINI, CS, and C4 is a loop counter that adds 1 to the previous value every time it is updated and returns to 0 after reaching the maximum value. Each counter is updated at short time intervals, and the updated value is appropriately stored in a lottery counter buffer 304 a set in a predetermined area of the RAM 304. Among these, in the lottery counter buffer 304a, the information corresponding to the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 is stored as a stored ball as an acquisition information storage means when a winning to the operation port 54 occurs. Stored in area 304b.

  The holding ball storage area 304b includes a holding area RE and an execution area AE. The holding area RE includes a first holding area RE1, a second holding area RE2, a third holding area RE3, and a fourth holding area RE4, and a lottery counter buffer 304a according to a winning history to the operation port 54. Each of the numerical information of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 stored in is stored in any of the holding areas RE1 to RE4 as holding information.

  In this case, in the first reservation area RE1 to the fourth reservation area RE4, when the winning to the operation port 54 is continuously generated a plurality of times, the first reservation area RE1 → the second reservation area RE2 → the third reservation area. Each numerical information is stored in time series in the order of RE3 → fourth reserved area RE4. Thus, by providing the four holding areas RE1 to RE4, up to four game balls winning histories to the operation port 54 are held and stored. In addition, the holding area RE includes a holding number storage area NA, and information for specifying the number of the payout history stored in the operation port 54 is stored in the holding number storage area NA. .

  Note that the number that can be reserved and stored is not limited to four, but may be any other number such as two, three, or five or more.

  The execution area AE is an area for moving each value stored in the first holding area RE1 of the holding area RE when starting the variable display of the main display unit 59. At the start of one game round Based on various numerical information stored in the execution area AE, determination of whether or not is made is performed.

  Each of the counters will be described in detail.

  For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 599, and after reaching the maximum value, it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is a loop counter similar to the jackpot random number counter C1 (value = 0 to 599). The jackpot random number counter C1 is periodically updated and stored in the reserved ball storage area 304b at the timing when the game ball wins the operation port 54.

  The value of the random number for winning the jackpot is stored as a success / failure table (availability information group) in a success / failure table storage area 303a as a success / failure information group storage means in the ROM 303. As the success / failure table, a success / failure table for the low probability mode (low probability success / failure information group) and a high probability mode's success / failure table (high probability success / failure information group) are set. That is, in the present pachinko machine 10, a low probability mode (low probability state) and a high probability mode (high probability state) are set as the lottery mode in the winning lottery means.

  In the gaming state in which the winning / failing table for the low probability mode is referred to at the time of the lottery, the number of random numbers that win the jackpot is two. On the other hand, in the gaming state in which the winning / failing table for the high probability mode is referred to at the time of the lottery, the number of random numbers that will win the jackpot is 20. If the winning probability in the high probability mode is higher than that in the low probability mode, the number of random numbers to be won is arbitrary.

  The jackpot type counter C2 is configured so that 1 is added in order within a range of 0 to 29, and after reaching the maximum value, it returns to 0. The big hit type counter C2 is periodically updated and stored in the holding ball storage area 304b at the timing when the game ball wins the operation port 54.

  In this pachinko machine 10, a normal jackpot result and a probable variation jackpot result are set, and the jackpot result is determined using the jackpot type counter C2.

  Specifically, the ROM 303 stores an allocation table (allocation information group) in an allocation table storage area 303b as an allocation information group storage unit. Then, a normal jackpot result (low probability special game result) and a probability variable jackpot result (high probability special game result) are set as the distribution destinations. In the distribution table, among the values of the jackpot type counter C2 of 0 to 29, 0 to 9 correspond to the normal jackpot result, and 10 to 29 correspond to the probability variation jackpot result.

  The normal jackpot result is a jackpot result in which the success / failure lottery mode becomes the low probability mode after the opening / closing execution mode is shifted to the open / close execution mode. In other words, the normal jackpot result is a jackpot result for shifting the gaming state to the normal jackpot state (special gaming state corresponding to low probability).

  The probability variation jackpot result is a jackpot result in which the success / failure lottery mode becomes the high probability mode after the opening / closing execution mode is shifted to the opening / closing execution mode. The high-probability mode continues until the lottery result in the success / failure lottery becomes a big hit state win and shifts to the big hit state by that. In other words, the probability variation jackpot result is a jackpot result in which the gaming state is shifted to the probability variation jackpot state (the special gaming state corresponding to high probability).

  Note that the normal gaming state in relation to each of the above gaming states refers to a state where the winning lottery mode is a low probability mode.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value and then returns to 0. The reach random number counter C3 is periodically updated and stored in the holding ball storage area 304b at the timing when the game ball wins the operation port 54.

  Here, in this pachinko machine 10, an expected effect is set as a kind of display effect in the 7-segment display device 112. Expected production means that in game machines corresponding to the jackpot winning, in the gaming machine in which the stop display result after the variable display becomes a special display result, the variable display (or variable display) of the symbol (picture) on the 7-segment display device 112 starts. It is a display state for making the player think that the display state is a variable display state that is likely to be the special display result before the stop display result is derived and displayed.

  In the expected effect, two types of reach display and a notice display for expecting generation of reach display or generation of a special display result at a stage before the reach display occurs are set.

  Reach display displays a combination of reach symbols that may be a combination of jackpot symbols by stopping and displaying some of the symbols displayed on the display screen of 7-segment display device 112 In this state, a display state in which the remaining symbols are displayed in a variable manner is included. In addition, with the combination of reach symbols displayed as described above, the remaining symbols are displayed in a variable manner, and a given character is displayed in the background to achieve reach effects, or the reach symbols are combined. In addition to the reduced display or non-display, a reach effect is included by displaying a predetermined character or the like on substantially the entire display screen.

  The variation type counter CS is, for example, incremented by 1 within a range of 0 to 198, and returns to 0 after reaching the maximum value. The variation type counter CS is used when the MPU 302 determines the variation display time (display duration) on the main display unit 59 and the symbol variation display time (display duration) on the 7-segment display device 112. The variation type counter CS is updated once every time a normal process to be described later is executed once, and is repeatedly updated even within the remaining time in the normal process. Then, the buffer value of the variation type counter CS is acquired when the variation display is determined at the start of variation display in the main display unit 59 and at the time of variation variation of the symbol by the 7-segment display device 112. When determining the variable display time, a variable display time table (variable display time information group) stored in advance in the variable display time table storage area 303c (variable display time information storage means) of the ROM 303 is referred to.

  The electric accessory release counter C4 is, for example, configured to increment one by one within a range of 0 to 250 and return to 0 after reaching the maximum value. The electric accessory release counter C4 is periodically updated and stored in the electric utility reservation area 304c at the timing when a game ball wins the through gate 55. Then, at a predetermined timing, a lottery is performed as to whether or not to control the electric accessory 54a to the open state based on the stored value of the electric accessory release counter C4.

  A main display unit 59 is connected to the output side of the MPU 302, and display control of the main display unit 59 is directly performed by the MPU 302. That is, display control of the main display unit 59 is executed in the MPU 302 at each game round.

  Further, the power failure monitoring board 305, the payout control device 91, and the sound lamp control device 71 are connected to the output side of the MPU 302. For example, a payout ball command is output to the payout control device 91 based on the winning determination result to the winning-corresponding winning portion. In this case, when outputting the prize ball command, the command information storage area 303e of the ROM 303 is referred to. When the winning to the general winning opening 52 is specified, a winning ball command corresponding to payout of 10 game balls is output, and when the winning to the variable winning device 53 is specified, 15 winning balls are output. When a winning ball command corresponding to paying out game balls is output and a winning to the operation port 54 is specified, a winning ball command corresponding to paying out four game balls is output.

  Various commands such as a change command, a type command, a change end command, an opening command, and an ending command are output to the sound lamp control device 71. In this case, the command information storage area 303e of the ROM 303 is referred to when these various commands are output. Details of these various commands will be described later. Each command is configured as information of a predetermined number of bytes, and various information is included as information of the predetermined number of bytes.

  Further, on the output side of the MPU 302, a variable winning drive unit 53a for opening / closing the variable winning device 53, an electric combination driving unit 54b for opening / closing the electric combination 54a of the operating port 54, and a main display unit 59 are connected. ing. The main control board 301 is provided with various driver circuits, and the MPU 302 performs drive control of various drive units through the driver circuits.

  That is, in the opening / closing execution mode, the MPU 302 performs drive control of the variable winning drive unit 53a so that the variable winning device 53 is opened and closed. In addition, when the electric combination 54a is won, the MPU 302 performs drive control of the electric combination drive unit 54b so that the electric combination 54a is opened and closed. In addition, display control of the main display unit 59 is executed by the MPU 302.

  The power failure monitoring board 305 relays between the main control board 301 and the power source and launch control device 92, and monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power source and launch control device 92. The payout control device 91 performs payout control of prize balls and rental balls by the payout device 89 based on the prize ball command input from the main control device 72.

  The power source and launch control device 92 is connected to, for example, a commercial power source (external power source) in a game hall or the like. Based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control board 301 and the payout control device 91, and the generated operating power is supplied through a predetermined power path. To do. Here, since the main control board 301 and the payout control device 91 are designed to operate at a direct current of 24V, the power supply and launch control device 92 supplies a direct current of 24V voltage. The power source and launch control device 92 is responsible for launch control of the game ball launch device 45, and the game ball launch device 45 is driven when predetermined launch conditions are met.

  The sound lamp control device 71 is configured to operate when a DC + 24V voltage is applied from the power supply and launch control device 92. The audio lamp control device 71 is equipped with an MPU 321. The MPU 321 is a ROM 322 storing various control programs executed by the MPU 321 and fixed value data, and a memory for temporarily storing various data when executing the control program stored in the ROM 322. A RAM 323. The MPU 321 drives and controls the lamp units 24, 25, 63 to 66 and the speaker unit 26 electrically connected to the audio lamp control device 71 based on various commands input from the main control device 72, and displays The control device 331 is controlled. The lamp units 24, 25, 63 to 66 and the speaker unit 26 are supplied with a DC voltage for operating power from the sound lamp control device 71. The display control device 331 executes display control of the 7-segment display device 112 based on the command input from the sound lamp control device 71. In this case, the sound lamp control device 71 determines the variation display time of symbols on the 7-segment display device 112 and the type of symbol combination to be finally stopped on the basis of various commands input from the main control device 72. At the same time, the lottery of the presence / absence of reach and the contents of reach production is executed.

  Here, the sound lamp control device 71 is electrically connected to the plasma discharge device 113 together with the illumination devices such as the lamp sections 24. Specifically, a discharge power supply circuit 350 that supplies an AC voltage that can cause discharge light emission in the plasma lamp 120 to the discharge electrode 150 is mounted on the discharge power supply substrate 124 of the plasma discharge apparatus 113. The power supply circuit 350 is connected to the sound lamp control device 71 via a connector provided on the discharge power supply board 124.

  The power supply circuit 350 for discharge will be described in detail with reference to FIG. FIG. 13 is a circuit diagram of a power supply circuit 350 for discharge. In the following description, the discharge power supply circuit 350 is also simply referred to as a power supply circuit 350.

  The power supply circuit 350 is connected to the discharge electrode 150 and the conductive seal 180. The power supply circuit 350 is supplied with + 12V DC voltage from the sound lamp control device 71. The power supply circuit 350 generates a high-frequency AC voltage from the +12 V DC voltage, and applies the AC voltage to the discharge electrode 150.

  Specifically, the power supply circuit 350 includes an oscillation circuit 351 connected to the sound lamp control device 71 and a transformer 352 as a transforming unit. The oscillation circuit 351 generates an AC voltage by oscillating with a DC voltage supplied from the sound lamp control device 71. The generated AC voltage is boosted by the transformer 352 and applied to the discharge electrode 150.

  Specifically, the oscillation circuit 351 includes a first transistor 361 and a second transistor 362 whose emitters serving as switching elements are grounded, and base resistors 363 and 364 connected to the bases of the transistors 361 and 362. It has. The bases of the transistors 361 and 362 are connected to the sound lamp control device 71 via the corresponding base resistors 363 and 364, and are supplied with a voltage of + 12V. As a result, the transistors 361 and 362 are controlled based on the base current instead of the base voltage, so that fluctuations in the collector current that can be caused by changes in the input voltage are suppressed. Although the transistors 361 and 362 are the same, the amplification factors are slightly different due to variations in the manufacturing stage.

  The transformer 352 includes two primary coils 365 and 366 and a secondary coil 367 connected in series, and a feedback coil 368 for switching the switching of the transistors 361 and 362. Although the primary side coils 365 and 366 are shown as two independent coils for convenience of explanation, in reality, a midpoint tap of the coil is derived using an integrated coil from the viewpoint of miniaturization of the circuit. . One end of the secondary coil 367 is connected to the discharge electrode 150, and the other end is connected to the conductive seal 180. The number of turns of the secondary side coil 367 is set to be larger than the number of turns of the primary side coils 365 and 366. Specifically, the number of turns of the integrated coil constituting the primary side coils 365 and 366 is 10 turns. In contrast, the number of turns of the secondary coil 367 is set to about 1000 turns. The secondary coil 367 is configured to boost the voltage applied to the series connection body of the primary coils 365 and 366 and to apply the boosted voltage to the discharge electrode 150. Yes.

  Here, the oscillation circuit 351 is configured to oscillate using the primary side coils 365 and 366 and the feedback coil 368. Specifically, the midpoint tap of the series connection body composed of the primary side coils 365 and 366, specifically, one end of each primary side coil 365 and 366 is connected to the sound lamp control device 71. The other end of the primary side coil 365 is connected to the collector of the first transistor 361, and the other end of the primary side coil 366 is connected to the collector of the second transistor 362. Corresponding to these primary side coils 365 and 366, the oscillation circuit 351 is provided with an oscillation capacitor 369 connected in parallel to the series connection body of the primary side coils 365 and 366. The oscillation capacitor 369 has one end connected to the emitter of the first transistor 361 and the other end connected to the emitter of the second transistor 362.

  The feedback coil 368 has one end connected to the base of the first transistor 361 and the other end connected to the base of the second transistor 362. The coils 365, 366, 367, and 368 have the same polarity.

  According to this configuration, when an operating voltage of +12 V is applied from the sound lamp control device 71, the operating voltage is converted into a base current by the base resistors 363 and 364, and the base current is applied to the transistors 361 and 362. Is granted. In this case, one of the transistors (the transistor with the higher amplification factor) is turned on. Here, for convenience of explanation, it is assumed that the first transistor 361 is turned on. Then, a current flows through the primary coil 365 corresponding to the first transistor 361 that is turned on. As a result, a voltage is applied to the oscillation capacitor 369, and resonance occurs between the oscillation capacitor 369 and the primary coil 365.

  Due to such resonance, a feedback current is generated in the feedback coil 368, and the feedback current is fed back to the bases of the transistors 361 and 362. In this case, the feedback current flows in a direction in which the transistors 361 and 362 are switched on / off with a change in the polarity of resonance. As a result, the first transistor 361 is turned off, and the second transistor 362 is turned on instead. Then, a current flows through the primary side coil 366. In this case, an induced electromotive force having a polarity opposite to that flowing in the primary coil 365 is generated.

  By repeating the above operation, the voltage at both ends of the series connection body of the primary side coils 365 and 366 becomes a sine wave, and the voltage of the sine wave is boosted by the secondary side coil 367 and output. . As a result, an AC voltage having a specific amplitude (eg, 1500 V) is applied to the discharge electrode 150 at a specific frequency (eg, 20 kHz). In this case, the specific frequency of the AC voltage is the oscillation frequency, and is determined by the inductors of the primary side coils 365 and 366 and the oscillation capacitor 369. In other words, the oscillation frequency can be said to be a resonance frequency of a resonance circuit (tank circuit) including the primary side coils 365 and 366 and the oscillation capacitor 369. Actually, since the primary side coils 365 and 366 are configured to take a mid-point tap of one coil, the oscillation frequency also depends on the mutual inductance.

  Further, the voltage waveform at the mid-point tap is a full-wave waveform, but since a + 12V DC voltage is supplied from the sound lamp control device 71, both interfere with each other and the resonance is inhibited. On the other hand, a choke coil 371 is provided between the midpoint tap and the sound lamp control device 71. This makes it difficult for the full-wave waveform voltage and the DC voltage from the sound lamp control device 71 to interfere with each other.

  Since the fuse 372 is provided in series between the choke coil 371 and the sound lamp control device 71, a failure due to overcurrent can be avoided. Further, a bypass capacitor 373 is provided in parallel with the line connecting the sound lamp control device 71 and the oscillation circuit 351, and the fluctuation of the DC voltage is suppressed.

  The conductive seal 180 is grounded via an NPN transistor 381 as switching means. The NPN transistor 381 is connected to the sound lamp control device 71, and switches the conductive seal 180 to the ground state or the floating state in response to a signal from the sound lamp control device 71.

  Specifically, the collector of the NPN transistor 381 is connected to the conductive seal 180, and the emitter is grounded. The base of the NPN transistor 381 is connected to the sound lamp control device 71. That is, the conductive seal 180 is an open collector.

  According to such a configuration, when the HI level signal corresponding to the voltage at which the NPN transistor 381 is turned on is input from the sound lamp control device 71 to the base, the NPN transistor 381 is turned on and the conductive seal 180 is grounded. The In this case, as already described, the induction portion 183 is formed by the conductive seal 180, and the discharge path is induced.

  On the other hand, when the LOW level signal is input to the base from the sound lamp control device 71, the NPN transistor 381 is turned off. In this case, the conductive seal 180 is in a floating state, and the potential of the spherical shell 141 is not easily disturbed (current does not flow through the conductive seal 180). For this reason, the discharge paths are difficult to aggregate. In other words, it can be said that the induction by the conductive seal 180 is loosened.

  From the above, when the signal output from the sound lamp control device 71 to the NPN transistor 381 is switched, the light emission mode of the discharge is canceled or relaxed between the induced state in which the discharge path is induced and the induced state. It will be switched to the state.

  Note that the configuration for switching the conductive seal 180 to the ground state or the floating state is not limited to this, and a relay circuit using a transistor or the like may be used, for example. Alternatively, a switching circuit that operates when an AC voltage is applied from the secondary coil 367 may be used. In short, as long as the conductive seal 180 is switched to the ground state or the floating state based on a signal from the sound lamp control device 71, the specific circuit configuration is arbitrary. However, the configuration using an open collector as in this embodiment is superior in that fewer electronic components are required.

  Here, as shown in FIG. 11, on the output side of the sound lamp control device 71, a shutter drive unit 391 that opens and closes the open / close shutter 221 is provided. The shutter drive unit 391 is an actuator made of a motor or the like, and drives the open / close shutter 221 based on a signal from the sound lamp control device 71. In the present embodiment, each opening / closing shutter 221 is configured to be opened / closed independently. That is, in addition to opening both of the open / close shutters 221 at the same time, it is possible to open / close only one of them. However, the opening / closing shutter 221 may be simultaneously opened / closed by one actuator.

<Processing Configuration in MPU 302 of Main Control Board 301>
Next, each control process executed by the MPU 302 of the main control board 301 will be described. In the MPU 302, a read process, a game time control process, and a game state transition process, which are a part of processes necessary for advancing a game, are distributed and executed in a timer interrupt process and a normal process. First, after describing timer interrupt processing, normal processing will be described.

  FIG. 14 is a flowchart showing timer interrupt processing. Note that this process is started periodically by the MPU 302 (for example, at a cycle of 2 msec).

  In step S101, a reading process is executed. In the reading process, the states of the various winning detection sensors are read, the states of the various winning detection sensors are determined, and the winning detection information is stored. In addition, when the winning detection sensors 311a to 311e corresponding to the generation of the winning ball detect the winning of the game ball, a winning ball command for instructing the payout control device 91 to pay out the winning ball is set. To do.

  In the subsequent step S102, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value.

  In subsequent step S103, the big hit random number counter C1, the big hit type counter C2, the reach random number counter C3, and the electric accessory release counter C4 are updated. Specifically, the jackpot random number counter C1, the jackpot type counter C2, the reach random number counter C3 and the electric accessory release counter C4 are each incremented by 1 and cleared to 0 when the counter values reach the maximum value.

  In a succeeding step S104, a through winning process for winning through the through gate 55 is executed. In the through-winning process, the value of the electric accessory release counter C4 updated in step S104 is used as an electric utility on the condition that the number of extra characters stored in the electric utility reservation area 304c is less than four. Store in the reserved area 304c.

  After that, in step S105, a winning process for the working port accompanying the winning of the working port 54 is executed. In the winning process for the operating port, when a winning has occurred in the operating port 54, the number of reserved starting storages stored in the holding ball storage area 304b is less than the upper limit number (for example, “4”). On the condition, the numerical information of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 updated in step S103 is stored in the holding area RE of the holding ball storage area 304b. In this case, the data is stored in the first reserved area among the empty reserved areas RE1 to RE4 of the reserved area RE, that is, the reserved area corresponding to the current start reserved memory number. After executing the process of step S105, the timer interrupt process is terminated.

  FIG. 15 is a flowchart showing normal processing. The normal process is a process that is started after a main process that is started when the power is turned on is executed. As its outline, the processing from step S201 to step S209 is executed as a 4 msec cycle processing, and the counter update processing of step S210 and step S211 is executed in the remaining time.

  In step S201, output data such as a command set in the timer interruption process or the previous normal process is transmitted to each control device on the sub side. Specifically, the presence or absence of a prize ball command is determined, and if a prize ball command is set, it is transmitted to the payout control device 91. Further, when a predetermined effect command is set, it is transmitted to the sound lamp control device 71.

  In the subsequent step S202, the variation type counter CS is updated. Specifically, the variation type counter CS is incremented by 1, and the counter value is cleared to 0 when the counter value reaches the maximum value.

  In subsequent step S203, a game number control process for controlling a game in each game time is executed. In the game times control process, jackpot determination, setting of symbol variation display by the 7-segment display device 112, display control of the main display unit 59, and the like are performed.

  Thereafter, in step S204, a game state transition process for shifting the game state is executed. In the gaming state transition process, when the game round corresponding to the big win is completed, the transition process to the opening / closing execution mode is executed, and the opening / closing process of the variable winning device 53 is started. Various commands for the opening / closing execution mode are transmitted to the sound lamp control device 71 when starting the opening / closing execution mode, during the opening / closing execution mode, and when ending the opening / closing execution mode. Further, when the opening / closing execution mode ends, the success / failure lottery mode transition is executed in correspondence with the jackpot type related to the game times that triggered the start of the mode.

  In the subsequent step S205, a demonstration display process is executed. In the demonstration display process, a predetermined demonstration start waiting period (for example, 0.1 sec) has elapsed without starting a new game time after the game time has ended in a state where the opening / closing execution mode is not in progress. A process for determining whether or not the process has been performed is executed. In addition, since the start of power supply to the MPU 302 or after the pachinko machine 10 is reset, a predetermined demonstration start waiting period (for example, 3 sec) has elapsed without newly starting game play. A process for determining whether or not the process has been performed is executed. If it is determined that the time has elapsed, a demonstration display command is transmitted to the sound lamp control device 71.

  In a succeeding step S206, an electric combination support process for driving and controlling the electric combination 54a provided in the operation port 54 is executed. In this electric combination support process, the information stored in the electric combination holding area 304c of the RAM 304 is used to determine whether or not to open the electric combination 54a, and to open / close the electric combination 54a.

  Thereafter, in step S207, a game ball launch control process is executed. In the game ball launch control process, the solenoid of the game ball launch device 45 is excited once in a predetermined period (for example, 0.6 sec) on condition that a launch permission signal is input from the power supply and launch control device 92. . Thereby, the game ball is launched toward the game area.

  In a succeeding step S208, it is determined whether or not the power interruption flag is stored in the RAM 304. The power interruption flag is a flag that is stored when the occurrence of power interruption is confirmed, and is deleted in the next main processing.

  If the power interruption flag is not stored, the last process of the plurality of processes that are repeatedly executed is completed. Therefore, whether or not the execution timing of the next normal process is reached in step S209, that is, the previous process It is determined whether or not a predetermined time (4 msec in the present embodiment) has elapsed since the start of normal processing. Then, the random number initial value counter CINI and the variation type counter CS are repeatedly updated within the remaining time until the next normal processing execution timing.

  That is, in step S210, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value. In step S211, the variation type counter CS is updated. Specifically, the variation type counter CS is incremented by 1 and cleared to 0 when the counter values reach the maximum value.

  Here, since the execution time of each process of steps S201 to S207 changes according to the state of the game, the remaining time until the execution timing of the next normal process is not constant and varies. Therefore, by repeatedly updating the random number initial value counter CINI using the remaining time, the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) can be updated at random. Similarly, The variation type counter CS can also be updated at random.

  On the other hand, if it is determined in step S208 that the power interruption flag is stored, the power interruption has occurred, so the power interruption processing from step S212 is executed. That is, in step S212, the generation of the timer interrupt process is prohibited, and then the RAM determination value is calculated and stored in step S213. After the access to the RAM 304 is prohibited in step S214, the power supply is completely shut down and processed. Continue infinite loop until no longer runs.

  Next, the game times control process of step S203 will be described with reference to the flowchart of FIG.

  In the game times control process, first, in step S301, it is determined whether or not the opening / closing execution mode is in effect. If it is in the opening / closing execution mode, the game turn control process is terminated without executing the processes after step S302. That is, in the open / close execution mode, the game times are not started regardless of whether or not a winning to the operation port 54 has occurred.

  If it is not in the opening / closing execution mode, it is determined in step S302 whether or not the main display unit 59 is in a variable display. When the main display unit 59 is not in a variable display, the process proceeds to the game turn starting process in steps S303 to S305.

  In the game turn starting process, first, in step S303, it is determined whether or not the number N of starting reserved balls is “0”. The case where the starting reserved ball number N is “0” means that the hold information is not stored in the hold ball storage area 304b. Accordingly, the game turn control process is terminated as it is.

  If the number N of starting reserved balls is not “0”, a data setting process for setting the data stored in the holding area RE of the holding ball storage area 304b for variable display in step S304 is executed. Specifically, the data stored in the first holding area RE1 of the holding area RE is shifted to the execution area AE. Thereafter, the data stored in the first reservation area RE1 to the fourth reservation area RE4 is shifted in order to the lower area side. Then, after executing the variation start process in step S305, the game times control process is terminated.

  Here, the variation start process of step S305 will be described with reference to the flowchart of FIG.

  In step S401, a success / failure determination process for determining whether or not the hold information corresponding to the current variation start process corresponds to the jackpot winning is executed. Specifically, with reference to the numerical information related to the jackpot random number counter C1 among the hold information shifted to the execution area AE and the hit / fail table corresponding to the current hit / fail lottery mode, whether or not the jackpot win is determined judge.

  In a succeeding step S402, it is determined whether or not the jackpot is won. If it is a big win, a type determination process is executed in step S403. In the type determination process, the jackpot type is specified with reference to the numerical information related to the jackpot type counter C2 and the distribution table among the hold information shifted to the execution area AE.

  In subsequent step S404, stop result setting processing corresponding to the jackpot result is executed. Specifically, information on the pattern mode that is finally stopped and displayed on the main display unit 59 in the game times related to the start of the change is specified from the stop result table for the jackpot result stored in the ROM 303 in advance. The specified information is stored in the RAM 304. In the jackpot result stop result table, the types of patterns that are stopped and displayed on the main display unit 59 are set differently for each jackpot result type. In step S404, the pattern is specified in step S403. Information on the pattern mode according to the type of the jackpot result is stored in the RAM 304.

  On the other hand, if it is determined in step S402 that it is not a big win, a stop result setting process for losing is executed in step S405. Specifically, the information on the pattern mode that is finally stopped and displayed on the main display unit 59 in the game round related to the start of the current fluctuation is stored in advance in the stop result table storage area 303d of the ROM 303 for use in the off time. The information is specified from the stop result table, and the specified information is stored in the RAM 304. The information on the pattern mode selected in this case is different from the information on the pattern mode selected in the case of the jackpot result.

  After executing the process of step S404 or step S405, the process for setting the variable display time is executed in step S406.

  In this process, the value of the variation type counter CS stored in the variation type counter buffer in the lottery counter buffer 304a of the RAM 304 is acquired. Further, it is determined whether or not reach display is generated on the 7-segment display device 112 in the current game round. Specifically, when the game times related to the start of the current variation is a jackpot result, it is determined that reach display occurs. Even if it is not a jackpot result, if the numerical information related to the reach random number counter C3 stored in the execution area AE is the numerical information corresponding to the occurrence of reach, it is determined that reach display occurs.

  When it is determined that the reach display occurs, the fluctuation display time information corresponding to the value of the current fluctuation type counter CS is acquired with reference to the reach generation fluctuation display time table stored in the ROM 303, and the fluctuation Display time information is set in a variable display time counter provided in the RAM 304. On the other hand, when it is determined that the reach display does not occur, the variable display time information corresponding to the value of the current variation type counter CS is acquired by referring to the reach non-occurrence variable display time table stored in the ROM 303. Then, the variation display time information is set in the variation display time counter. Incidentally, the variable display time that can be acquired with reference to the non-reach generation variable display time table is different from the variable display time that can be acquired with reference to the reach generation variable display time table.

  Note that the variable display time information when no reach occurs is set so that the variable display time is shortened as the number N of starting reserved balls increases.

  After executing the variable display time setting process in step S406, a variable command and a type command are set in step S407. The change command includes information on the change display time. Here, as described above, the fluctuation display time obtained by referring to the non-reach occurrence fluctuation display time table is different from the fluctuation display time obtained by referring to the reach occurrence fluctuation display time table. Even if the information on the occurrence of reach is not included in the command for use, the audio lamp control device 71 which is the control device on the sub-side can specify the presence or absence of the occurrence of reach from the information on the variable display time. In this regard, it can be said that the change command includes information indicating whether or not reach has occurred. Note that the change command may include information that directly indicates whether or not reach has occurred.

  The type command includes game result information. That is, the type command includes, as game result information, any one of normal jackpot result information, probability variation jackpot result information, and outlier result information.

  The variation command and type command set in step S407 are transmitted to the audio lamp control device 71 in step S201 in the normal process (FIG. 15). After performing the process of step S407, the display of the variation of the pattern is started on the main display unit 59 in step S408. Then, this variation start process is terminated.

  Returning to the description of the game times control process (FIG. 16), when the main display unit 59 is in a variable display, the processes of steps S306 to S309 are executed. In this process, first, in step S306, it is determined whether or not the current game time variation display time has elapsed.

  If the variable display time has not elapsed, the variable display process is executed in step S307. In the variable display process, the display mode on the main display unit 59 is changed. Thereafter, the game times control process is terminated.

  If the change display time has elapsed, change end processing is executed in step S308. In the variation end process, the information stored in the RAM 304 in the process of step S404 or step S405 is specified, and the main display unit 59 is displayed so that the pattern form corresponding to the information is displayed on the main display unit 59. Control display.

  In the subsequent step S309, a change end command is set. The variation end command set here is transmitted to the sound lamp control device 71 in step S201 in the normal process (FIG. 15). The sound lamp control device 71 ends the effect in the game round based on the received variation end command. In addition, a command corresponding to the command is transmitted from the sound lamp control device 71 to the display control device 331, and the display control device 331 displays the final stop symbol combination in the game times in a definite display (final stop display). Thereafter, the game times control process is terminated.

<About processing executed by the MPU 321 of the sound lamp control device 71>
Next, the change command handling process executed by the MPU 321 of the sound lamp control device 71 will be described with reference to the flowchart of FIG. 18 and FIG. FIGS. 19A to 19C are explanatory views for explaining display modes displayed on the display unit 61. FIG. The corresponding process is repeatedly activated at a predetermined cycle (for example, 2 msec cycle). In the variation command response processing, when the variation command transmitted by the main control device 72 is received, processing corresponding to the information included in the received variation command is executed.

  First, in step S501, based on the change command and the type command, it is determined whether or not the jackpot is won, and if the jackpot is won, the type and the change display time are grasped. In this case, the presence / absence of reach is also determined based on the variable display time.

  Thereafter, in step S502, it is determined whether or not the game result of the current game round is a big hit based on the grasping result in step S501. If it is not a big hit, a deviation variation pattern determination process is executed in step S503. In this process, the display mode of the 7-segment display device 112 corresponding to the detachment result is determined.

  Specifically, the ROM 322 of the sound lamp control device 71 is provided with a variation pattern table storage area 322a, and the variation pattern table for detachment is stored in the variation pattern table storage area 322a. In the table, a plurality of types of variation patterns corresponding to the detachment results executed in the 7-segment display device 112 are set. The fluctuation pattern table is set according to the fluctuation display time and the presence / absence of reach. In step S503, the variation pattern of the current game time is determined by referring to the variation pattern table based on the grasp result of step S501. Note that the variation pattern includes a combination of symbols that are finally stopped in the 7-segment display device 112.

  Then, it progresses to step S504 and the discharge effect lottery process of whether to perform the discharge effect using the plasma discharge apparatus 113 is performed. Specifically, an effect lottery counter area 323a is provided in the RAM 323 of the sound lamp control device 71, and an effect lottery counter that is updated at a predetermined cycle is stored in the area. In step S504, the current value of the effect lottery counter is acquired, and it is determined whether or not the value of the counter corresponds to a predetermined winning value.

  If it is determined that the discharge effect is not won, the process proceeds to step S505, and the open / close shutter 221 is set to the closed state. In step S506, a process of transmitting a fluctuation pattern command corresponding to the current fluctuation pattern to the display control device 331 is executed, and this command response process is terminated. Based on the reception of the variation pattern command, the display control device 331 starts the variation display of the symbols displayed on the 7-segment display device 112 and executes a process of maintaining the variation display over a predetermined period. . And when the said predetermined period passes, the process which displays the stop result corresponding to a fluctuation pattern command, ie, the stop result corresponding to a detachment result, is performed. Thereby, only the symbol of the 7-segment display device 112 is displayed as shown in FIG. In this case, since the opening / closing shutter 221 is closed, the plasma discharge device 113 is not visually recognized.

  On the other hand, when it is determined that the discharge effect is won (when it is determined that the value of the effect lottery counter matches the winning value), processing for the discharge effect is executed in steps S508 to S511. Specifically, the mode of the conductive seal 180 is determined and the mode of opening / closing operation of the opening / closing shutter 221 is determined. In this case, the light emission mode of the discharge effect is set to be different between the case where the reach display is performed and the case where it is not.

  First, in step S508, it is determined whether or not it is a game time in which reach display is performed based on the grasp result in step S501. If it is determined that the reach display is not performed, the potential of the conductive seal 180 is set to floating in step S509. Specifically, a LOW level signal is output to the base of the NPN transistor 381 of the power supply circuit 350.

  Thereafter, in step S510, the operation mode of the open / close shutter 221 is set to a mode corresponding to the result of the detachment. The mode corresponding to the detachment result is a mode in which the opening / closing shutter 221 is closed after the opening / closing operation of the opening / closing shutter 221 is performed for a predetermined period.

  In step S511, the opening / closing operation of the opening / closing shutter 221 is started. In step S512, the variation pattern command output process is executed, and the corresponding process ends.

  When such processing is executed, as shown in FIG. 19B, the variation display of the symbols (numbers) of the 7-segment display device 112 and the light emission mode of discharge of the plasma discharge device 113 as a discharge effect are the case opening. It is visually recognized through 111a. In this case, both are displayed overlapping. Since the conductive seal 180 is set to be floating, the discharge path is not aggregated. For this reason, the brightness | luminance of the plasma discharge apparatus 113 is small compared with the case where the discharge path is concentrated.

  FIG. 19B shows the case where the open / close shutter 221 is in the open state. However, when the symbol change display is finished, the open / close shutter 221 is closed, so that the plasma discharge device 113 is visually recognized. Instead, only the symbol of the 7-segment display device 112 is displayed.

  If it is determined that the reach display is to be performed (step S508: YES), a process of grounding the conductive seal 180 is executed in step S512. Specifically, an HI level signal is output to the base of the NPN transistor 381 of the power supply circuit 350. As a result, the NPN transistor 381 is turned on, and the conductive seal 180 is grounded.

  Thereafter, in step S513, the operation mode of the open / close shutter 221 is set to a mode corresponding to reach display. The aspect corresponding to the reach display is the same as the aspect corresponding to the detachment result except that the opening / closing operation period is set longer than the aspect corresponding to the detachment result.

  In step S511, the opening / closing operation of the opening / closing shutter 221 is started. In step S507, the variable pattern end command output process is executed, and the corresponding process ends.

  When such processing is executed, the variation display of the symbols (numbers) of the 7-segment display device 112 and the light emission mode of the discharge of the plasma discharge device 113 as a discharge effect are overlapped and visually recognized through the case opening 111a. The In this case, since the conductive seal 180 is grounded, the discharge paths are concentrated. For this reason, as shown in FIG. 19C, the luminance of the plasma discharge device 113 is higher than that in the case where the reach display is not performed. Thereby, the light emission aspect of the plasma discharge apparatus 113 is visually recognized more clearly.

  When it is determined in step S514 that the jackpot is won (step S502: YES), the process proceeds to step S514, and the jackpot variation pattern determination process is executed. In this process, the display mode of the 7-segment display device 112 corresponding to the jackpot result is determined.

  Specifically, a variation pattern table for jackpot is stored in the variation pattern table storage area 322a. In this table, a plurality of types of variation patterns corresponding to the jackpot result executed in the 7-segment display device 112 are set, and each variation pattern is set according to the jackpot type and the variation display time. In step S, the variation pattern of the current game time is determined by referring to the variation pattern table based on the grasping result in step S514.

  The variation pattern includes a combination of symbols corresponding to the jackpot result that is finally stopped in the 7-segment display device 112. Specifically, as a combination of symbols corresponding to the jackpot result, an odd combination of the same numbers is set if it is a probabilistic jackpot result, and an even combination of the same numbers is set if it is a normal jackpot result. Is set.

  Then, the process for performing a discharge effect is performed in step S515 and step S516. In this case, a lottery for determining whether or not to perform a discharge effect is not performed. That is, in the case of a jackpot result, unlike the case of a loss result, a discharge effect is always executed. In addition, it is good also as a structure which performs the lottery process of whether to perform a discharge effect also when it is a jackpot result. In this case, it is preferable to set the winning probability to be higher than that in the lottery process in the case of a losing result.

  In step S515, processing for grounding the conductive seal 180 is executed. Specifically, a HI level signal is output to the base of the NPN transistor 381 so that the NPN transistor 381 is turned on. In the subsequent step S516, processing for setting the operation mode of the jackpot opening / closing shutter 221 is executed. The operation mode of the jackpot opening / closing shutter 221 is an operation mode in which the opening / closing shutter 221 is set to an open state after performing a series of opening / closing operations, unlike the release operation mode and the reach operation mode. is there.

  Thereafter, the opening / closing operation of the opening / closing shutter 221 is started in step S511, and after the fluctuation pattern command is output to the display control device 331 in step S507, the present handling process is terminated.

  When such processing is executed, the variation display of the symbols (numbers) of the 7-segment display device 112 and the light emission mode of the discharge of the plasma discharge device 113 as a discharge effect are visually recognized through the case opening 111a.

  In addition, after the series of opening / closing operations of the opening / closing shutter 221 is performed, the opening / closing shutter 221 is in an open state, so that the stop result of the 7-segment display device 112 and the light emission mode of the plasma discharge device 113 overlap and display. Is done.

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

  A conductive seal 180 was attached to the outer peripheral surface of the cover member 161. Thereby, since the discharge path is concentrated by grounding the conductive seal 180, the luminance of the discharge light emission is improved. Accordingly, the discharge light emission can be suitably viewed, and the degree of attention to the game can be increased through a discharge effect that displays the discharge light emission.

  Further, an NPN transistor 381 for switching the conductive seal 180 between a floating state and a ground state is provided. Thereby, it becomes possible to switch the light emission mode of discharge between a state in which the luminance is improved and a state in which the luminance is not. Therefore, for example, when the reach display is performed, the ground state is set, and when the reach display is not performed, the floating state is set.

  A mirror member 114 is disposed behind the case opening 111a, a seven-segment display device 112 is disposed behind the mirror member 114, and a plasma discharge device 113 is disposed above the mirror member 114. The transmitted light L1 transmitted through the mirror member 114 out of the light generated from the 7-segment display device 112 and the reflected light L2 reflected from the mirror member 114 out of the light generated from the plasma lamp 120 are in the same direction. The mirror member 114 is inclined and arranged. As a result, it is possible to display the discharge light emission or the variation display of the symbols on the same display unit 61, and it is possible to display both in an overlapping manner. Therefore, the display mode displayed on the display unit 61 can be made novel.

  Here, in order for the 7-segment display device 112 arranged behind the mirror member 114 to be visually recognized by the display unit 61, the transmission that is transmitted from the 7-segment display device 112 side toward the case opening 111a. The light emission intensity of the light L1 needs to be higher than the light transmitted from the case opening 111a side to the 7-segment display device 112 side.

  On the other hand, in the present embodiment, the 7-segment display device 112 that easily secures a relatively high light emission intensity is disposed behind the mirror member 114, and the plasma discharge device 113 with a relatively low light emission intensity is disposed on the mirror member 114. Was placed above. Thereby, the emission intensity of the transmitted light L1 can be easily ensured, and the display mode of the 7-segment display device 112 and the light emission mode of discharge of the plasma discharge device 113 can be suitably viewed via the display unit 61. it can.

  The plasma discharge device 113 is unitized including a discharge power supply substrate 124 on which a discharge power supply circuit 350 is mounted. The plasma discharge device 113 is disposed at a position separated from the sound lamp control device 71. Yes. Thereby, it is possible to avoid the inconvenience that the sound lamp control device 71 malfunctions due to noise generated from the power supply circuit 350 for discharge.

  More specifically, in order to cause the plasma lamp 120 to emit discharge light in a situation where the inner wall portion of the electrode recess 152 as an insulator is provided between the discharge electrode 150 and the discharge gas 144, the discharge electrode It is necessary to apply a high voltage (for example, 1500 V) to 150 with a high frequency (for example, 20 kHz). On the other hand, since the voltage supplied to the power supply circuit 350 is DC + 12V from the sound lamp control device 71, the power supply circuit 350 includes an oscillation circuit 351 and a transformer 352. For this reason, noise is generated by the coil used in the transformer 352, and the noise may adversely affect surrounding peripheral devices. On the other hand, in the present embodiment, a discharge power supply substrate 124 on which the power supply circuit 350 is mounted is provided separately, and the plasma discharge device 113 is unitized including the discharge power supply substrate 124 and the plasma discharge device 113. Are arranged at positions separated from the sound lamp control device 71. Thereby, since the influence by the noise given to the audio lamp control device 71 is weakened, the above inconvenience can be avoided.

  In this case, the audio lamp control device 71 need only have a configuration such as a connector for electrically connecting the MPU 321 and the power supply circuit 350. Thereby, since the change of the structure of the sound lamp control device 71 that can be caused by driving and controlling the plasma discharge device 113 can be reduced, the plasma discharge device 113 can be attached relatively easily.

  A cover member 161 covering the plasma lamp 120 was provided. Thereby, the inconvenience that the plasma lamp 120 is broken by an external impact can be avoided. In this case, since a part of the discharge light is absorbed by the cover member 161, the luminance of the discharge light emission is lowered. On the other hand, according to the present embodiment, the luminance of discharge light emission visually recognized on the display unit 61 is enhanced by attaching the conductive seal 180 to the cover member 161. That is, it can be said that the inconvenience that may be caused by providing the cover member 161 with the conductive seal 180 can be avoided.

  Further, the cover member 161 includes a cover-side cylindrical portion 162, and the outer diameter of the cover-side cylindrical portion 162 is set to the same dimension without depending on the traveling direction X. And it was set as the structure which affixes the electroconductive seal | sticker 180 on the outer peripheral surface of the cover side cylindrical part 162. FIG. As a result, the conductive seal 180 looks linear in the reflected image of the mirror member 114. Therefore, since the conductive seal 180 is not conspicuous, it is possible to avoid the inconvenience that the conductive seal 180 makes it difficult to see the light emission mode of discharge.

  Furthermore, since the conductive seal 180 is affixed to the outer peripheral surface of the cover-side cylindrical portion 162, the action of the guide portion 183 is weaker than that of the configuration that is affixed to the inner peripheral surface. For this reason, a discharge path will fluctuate compared with the structure affixed on an internal peripheral surface. Therefore, fluctuations in the discharge path can be ensured while inducing the discharge path.

  An open / close shutter 221 that can be opened and closed in an open state in which the plasma lamp 120 is visually recognized and a closed state in which the plasma lamp 120 is difficult to visually recognize is provided. Thus, by opening / closing the open / close shutter 221, it is possible to make the light emission mode of discharge visible or not visually recognized.

  Here, when the discharge is started in the plasma discharge apparatus 113, a high electric field is locally generated, and the high electric field generates a larger noise than normal time (operation time). The noise may adversely affect surrounding peripheral devices such as the 7-segment display device 112 and the display control device 331 disposed behind the 7-segment display device 112. On the other hand, in the present embodiment, the plasma discharge device 113 can be made visible or not visible by opening and closing the open / close shutter 221, so that the discharge is performed in the plasma discharge device 113 regardless of the presence or absence of the discharge effect. The light emission state can be maintained. Thereby, the bad influence by the noise which generate | occur | produces at the time of the discharge start in the plasma discharge apparatus 113 can be suppressed.

<Other embodiments>
In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows. Incidentally, each of the following configurations may be applied alone to the configuration of the above embodiment, or may be applied to the configuration of the above embodiment in a predetermined combination. Moreover, you may apply the following each structure to embodiment which is not illustrated as an application object of the structure.

  (1) In the above embodiment, the discharge electrode 150 is provided outside the internal space 143, and the discharge light emission is performed by applying an AC voltage to the discharge electrode 150. However, the present invention is not limited to this. For example, the discharge electrode 150 may be disposed in the internal space 143. Even in this case, discharge is performed. However, when attention is paid to the deterioration of the discharge gas 144, the stability of the light emission mode of discharge, and the damage of the plasma lamp 120 due to dielectric breakdown, the configuration in which the discharge electrode 150 is disposed outside the internal space 143 is superior.

  (2) In the above embodiment, the plasma discharge device 113 is accommodated in the accommodation space S1 of the main body case 111. However, the present invention is not limited to this. For example, the plasma discharge device 113 may not be accommodated in the accommodation space S1. In this case, an opening for inserting the discharge light emission of the plasma discharge device 113 into the mirror member 114 is separately provided in the main body case 111. Even in this case, since the region where the discharge path is concentrated is covered by the light-shielding conductive seal 180, insertion of light from the outside is restricted by the conductive seal 180. As a result, it is possible to suppress the inconvenience that discharge light emission is difficult to see due to insertion of light from the outside.

  In particular, the width dimension of the conductive seal 180 may be set so that the entire discharge electrode 150 including the tip portion is accommodated in a region surrounded by the conductive seal 180.

  (3) In the above embodiment, the tip of the discharge electrode 150 is arranged at the center of the spherical shell 141 of the plasma lamp 120. However, the configuration is not limited to this, and the tip is arranged at a position shifted from the center. May be. However, from the viewpoint of the magnitude of the fluctuation of the discharge path, the configuration in which the tip of the discharge electrode 150 is arranged at the center of the spherical shell 141 is superior.

  (4) In the above-described embodiment, the conductive paint 191 is applied. However, the present invention is not limited to this. For example, a conductive thin film may be deposited. In short, the conductive layer only needs to be formed on the inner peripheral surface on the bottom 153 side of the electrode recess 152, and the specific material and manufacturing method thereof are arbitrary.

  Further, the conductive paint 191 may not be provided. Even in this case, since the steel wool 192 is in contact with the inner wall surface of the electrode recess 152, the discharge path is easily formed in a direction intersecting the axial direction of the discharge electrode 150. However, the configuration in which the conductive paint 191 is provided is easier to form the discharge paths in the intersecting direction.

  (5) In the embodiment described above, the steel wool 192 is used as a multi-contact connection with the electrode recess 152, but the invention is not limited to this, and any assembly of wool-like metal fibers may be used. Alternatively, a solution containing a conductive colloid substance may be injected. Even in this case, the discharge electrode 150 and the conductive paint 191 are electrically connected through contact with the colloidal particles, and a multi-contact connection is realized. The point is that the conductive paint 191 is electrically connected to the conductive paint 191 (in the case where the conductive paint 191 is not provided as shown in the above (4)) with multiple contacts. That's fine.

  Moreover, you may provide the electroconductive part used as surface contact with respect to the conductive coating material 191 instead of multi-contact connection. However, in the case of the surface contact configuration, the voltage is evenly applied to the conductive paint 191, so the number of discharge paths is reduced and the discharge in the direction intersecting the axial direction is less likely to occur. In view of the point, the configuration with multi-contact connection is superior.

  (6) In the said embodiment, you may improve the reflectance of the back surface in which the adhesive of the conductive seal 180 is apply | coated. Thereby, the light generated by the discharge light emission is reflected on the back surface of the conductive seal 180, and the region surrounded by the conductive seal 180, that is, the region where the discharge light emission is performed by the plasma lamp 120 is brightened. Can do. In this case, since the difference in light intensity between the discharge path and its surroundings becomes small, the discharge path looks blurred. Therefore, when attention is paid to making the discharge path clearly visible, the configuration in which the reflectance on the back surface is reduced is superior.

  In addition, as a specific structure which improves the reflectance of a back surface, the structure which forms a thin film with a high reflectance in the lower layer of an adhesive can be considered.

  (7) In the above embodiment, the conductive seal 180 is configured to be grounded. However, the present invention is not limited to this. For example, an offset voltage may be applied. Even in this case, since the induction part 183 is formed in the plasma lamp 120, the discharge paths can be concentrated.

  Here, an AC voltage having a smaller amplitude and the same phase as that of the AC voltage applied to the discharge electrode 150 may be applied to the conductive seal 180. As a result, the potential difference between the discharge electrode 150 and the conductive seal 180 is smaller than that of the configuration in which the conductive seal 180 is grounded, so that the induction of the discharge path by the conductive seal 180 becomes loose. That is, by applying a voltage to the conductive seal 180 so that the potential difference between the discharge electrode 150 and the conductive seal 180 is reduced, the induction of the discharge path by the conductive seal 180 can be relaxed, and the discharge path can be reduced. It can be dispersed moderately.

  On the other hand, when an AC voltage having a phase opposite to that of the AC voltage applied to the discharge electrode 150 is applied, the potential difference between the discharge electrode 150 and the conductive seal 180 causes the conductive seal 180 to be grounded. Since it becomes comparatively large, a discharge path | route can be integrated more.

  (8) In the above embodiment, the conductive seal 180 is used as the auxiliary electrode. However, the present invention is not limited to this. For example, a ring-shaped electrode may be attached. However, if attention is paid to the point that the auxiliary electrode is not easily noticeable and the viewpoint of ease of attachment, the configuration using the conductive seal 180 is superior.

  The conductive seal 180 is made of a light-shielding metal, but is not limited thereto, and for example, a transparent metal (ITO or the like) may be used. In this case, even when the cover member 161 is attached to the hemispherical shell portion 163 or the spherical shell portion 141 of the plasma lamp 120, the conductive seal is not conspicuous so that it is difficult to disturb discharge light emission.

  Further, a metal film may be deposited instead of the conductive seal 180. In this case, the metal film may be a transparent metal thin film such as ITO. Thereby, the said effect can be show | played.

  (9) In the above embodiment, the cover member 161 is provided. However, the present invention is not limited to this, and the cover member 161 may not be provided. In this case, the plasma lamp 120 is easily broken by an external impact. In addition, since the conductive seal 180 is attached to the plasma lamp 120, the plasma lamp 120 may be broken at the time of attachment, and the attached conductive seal 180 looks like a ring and is easily noticeable. In view of these points, the configuration in which the cover member 161 is provided is superior.

  (10) In the above embodiment, the frequency of the AC voltage applied to the discharge electrode 150 is constant. However, the present invention is not limited to this. For example, the frequency may be variably controlled. Specifically, as shown in FIG. 20, the oscillation capacitor 369 of the oscillation circuit 351 is replaced with a variable capacitor 401, and a switching drive unit 402 for switching the capacitance of the variable capacitor 401 is separately provided. Then, the switching drive unit 402 and the audio lamp control device 71 are electrically connected, and the audio lamp control device 71 drives and controls the switching drive unit 402 based on the variation command transmitted from the main control device 72. Good. For example, when a discharge effect is performed in the case of disconnection, the oscillation frequency and the amplitude are reduced by drivingly controlling the switching drive unit 402 so that the capacitance of the variable capacitor 401 is increased. On the other hand, when a discharge effect is performed in a situation where reach display is performed, the switching drive unit 402 is driven and controlled so that the electrostatic capacitance of the variable capacitor 401 is reduced, thereby increasing the oscillation frequency and amplitude. Thereby, the brightness of the discharge light emission of the plasma lamp 120 can be relatively increased as compared with the discharge effect in the case of detachment. Therefore, a difference occurs in the discharge effect between reach display and out-of-display, thereby increasing the degree of attention to reach display.

  In particular, the oscillation frequency is determined by the capacitances of the inductors of the primary coils 365 and 366 and the variable capacitor 401, and the dependence on the voltage value of the DC voltage from the sound lamp control device 71 is low. For this reason, it is possible to increase the AC voltage, specifically, to increase the amplitude without changing the DC voltage from the sound lamp control device 71. Therefore, the frequency change can be easily realized using the existing sound lamp control device 71.

  The analog control using the variable capacitor 401 and the switching drive unit 402 is shown as the configuration for changing the frequency. However, the present invention is not limited to this. For example, the capacitance of the oscillation capacitor may be changed by digital control.

  (11) The plasma discharge device 113 may be used for the demonstration display. Specifically, the open / close shutter 221 is opened. In this case, the conductive seal 180 may be set to be floating. Thereby, a difference can be produced in the light emission mode of discharge in demonstration display and reach display.

  When the configuration (10) is applied, the capacitance of the variable capacitor 401 may be set large so that the frequency becomes low. Thereby, in addition to the above effects, power consumption can be reduced and deterioration due to heat generation can be reduced in a standby state where no game is played.

  (12) In the above embodiment, the power supply circuit 350 includes the oscillation circuit 351 and the transformer 352. However, the present invention is not limited to this, and a function of converting a DC voltage into an AC voltage and boosting the converted AC voltage. The specific circuit configuration is arbitrary.

  (13) The voltage applied to the discharge electrode 150 is not limited to a sine wave, and may be a triangular wave, a sawtooth wave, or the like. The point is that it has a predetermined cycle and the discharge gas 144 has a voltage that can provide an ionizable electric field.

  (14) In the above-described embodiment, the display mode of the 7-segment display device 112 and the light emission mode of discharge are visually recognized on the same display unit 61. However, the display mode is not limited to this, and each dedicated display unit It is good also as a structure which provides.

  (15) In the above embodiment, the plasma discharge device 113 is arranged above the mirror member 114 and the seven-segment display device 112 is arranged behind the mirror member 114. However, the present invention is not limited to this, and both may be arranged in reverse. Good. However, in view of suitably visualizing discharge light emission performed in the plasma discharge device 113 of the plasma discharge device 113, the configuration in which the 7-segment display device 112 is arranged behind the mirror member 114 is superior.

  Further, the mirror member 114 may not be provided. In this case, a transmissive liquid crystal panel is provided behind the case opening 111a, and a plasma discharge device 113 is provided behind the transmissive liquid crystal panel. A backlight as a light source is provided behind the transmissive liquid crystal panel and on the side surface of the main body case 111. Thereby, the light emission of the plasma lamp 120 of the plasma discharge device 113 is visually recognized through the liquid crystal panel. The symbols are displayed on the display unit 61 by displaying the symbols on the transmissive liquid crystal panel. However, in the case of such a configuration, the light emitted from the plasma lamp 120 is absorbed by the transmissive liquid crystal panel. Therefore, it is necessary to increase the intensity of light generated by the discharge light emission by the absorbed amount. In view of this point, the configuration using the mirror member 114 is superior.

  (16) In the above embodiment, the mirror member 114 in which the transmittance and the reflectance are set to be the same is used. However, the present invention is not limited to this. For example, a mirror member in which the reflectance is set larger than the transmittance is used. It may be used. Thereby, since the intensity of light from the plasma discharge device 113 can be made higher than the intensity from the 7-segment display device 112 side, the discharge light emission of the plasma discharge device 113 can be seen more suitably.

  (17) In the above embodiment, a lens may be provided between the mirror member 114 and the plasma discharge device 113. The position of the lens may be adjusted such that the reflected image of the mirror member 114 is displayed in a state where the plasma discharge device 113 is enlarged or reduced. As a result, the plasma discharge device 113 can be displayed in a reduced size as shown in FIG. 21A, or the plasma discharge device 113 can be displayed in an enlarged manner as shown in FIG. 21B.

  In particular, it is desirable that the plasma discharge device 113 be small in size from the viewpoint of space and ease of securing a voltage necessary for discharge light emission. On the other hand, when the plasma discharge device 113 is downsized, the area where the discharge light emission is displayed becomes small, and there is a risk that the degree of attention to the discharge effect will decrease. In contrast, by performing an enlarged display of the plasma discharge device 113 using a lens, it is possible to reduce the size of the plasma discharge device 113 while avoiding the above disadvantages.

  Note that the mirror member 114 may be curved instead of the lens. However, in this case, the display mode of the 7-segment display device 112 may be a curved image by diffracting the transmitted light L1. In view of this point, a configuration in which a lens is separately provided is superior.

  (18) In the above-described embodiment, the plasma lamp 120 is switched between the state in which the plasma lamp 120 is visually recognized and the state in which the plasma lamp 120 is not visually recognized by the opening / closing operation of the opening / closing shutter 221, but the present invention is not limited thereto. The above switching may be executed by on / off control of voltage application to 150. However, in this case, other electronic devices may malfunction due to noise generated when starting discharge light emission in the plasma lamp 120, and the plasma lamp 120 is reflected in a situation where no discharge effect is performed. Can occur. In view of these points, the configuration in which the open / close shutter 221 is provided is superior.

  (19) In the above-described embodiment, the plasma lamp 120 includes the spherical spherical shell portion 141 and is formed in a spherical shape as a whole. However, the present invention is not limited thereto, and may be, for example, an egg shape or a cylindrical shape. Good. However, from the viewpoint of the fluctuation of the discharge path, the plasma lamp 120 is preferably spherical.

  (20) In the above-described embodiment, the number of operating ports 54 is one, but the number is not limited to this. For example, the operating port 54 may be a lower operating port, and an upper operating port may be provided above the lower operating port. In this case, the hold information related to winning in the upper working port and the hold information related to winning in the lower working port are stored separately, and the hold information related to winning in the lower working port is preferentially digested. A configuration may be applied, and conversely, a configuration in which the hold information related to winning in the upper working port is preferentially digested may be applied. In this case, among the hold information acquired based on the winning to the upper working port and the hold information acquired based on the winning to the lower working port, the former hold information can be set as an opportunity to execute the hold notice The latter hold information may be set as a trigger for executing the hold notice.

  In the above configuration, the plurality of operation ports are not arranged vertically, but a first operation port corresponding to the upper operation port and a second operation port corresponding to the lower operation port are arranged side by side. It is good also as a structure made into these, and it is good also as a structure by which these both operation ports were arranged in parallel diagonally. Furthermore, it is good also as a structure which arrange | positions both operation openings apart so that only the winning to a 1st operation opening or the winning to a 2nd operation opening can be aimed according to the operation mode of a launching handle. In this case, it becomes possible for the player to aim for only one winning of the first operating port or the second operating port in accordance with the hold notice.

  Further, in the above configuration, the main display unit 59 is obtained based on the first display area for displaying the result of the determination of whether or not the hold information is obtained based on the winning to the upper working port, and the winning to the lower working port. You may provide the 2nd display area which displays the result of the decision | availability determination of pending | holding information. In this case, the variation display of the pattern is displayed in the first display area based on the fact that the hold information acquired based on the winning to the upper working opening is the target of the determination of the success or failure. At the same time, the stop result corresponding to the determination of success / failure is displayed, and the display of the variation of one game time is ended. In addition, the variable display of the pattern is started in the second display area before or after the hold information acquired based on the winning to the lower working port becomes the target of the determination of the success or failure. At the same time, a stop result corresponding to the determination of success / failure is displayed, and the change display for one game time is ended.

  (21) In the above embodiment, the opening / closing control mode of the opening / closing execution mode is the same for the normal jackpot result and the probability variation jackpot result, but the present invention is not limited to this. For example, the configuration may be different. Good. Specifically, the high-frequency winning mode and the low-frequency winning mode are set so that the occurrence frequency of winning in the variable winning device 53 is relatively high between the start and end of the opening / closing execution mode. May be. For example, in the high-frequency winning mode, the opening / closing operation of the variable winning device 53 is performed 15 times (number of times for high frequency) from the start to the end of the opening / closing execution mode, and 30 sec (high frequency time) elapses for one opening. It is set so as to continue until the number of winnings to the variable winning device 53 reaches 10 (high frequency). On the other hand, in the low frequency winning mode, for example, the opening / closing operation of the variable winning device 53 is performed twice (number of times for low frequency) from the start to the end of the opening / closing execution mode, and one opening is 0.2 sec (low frequency). It is set to continue until the (time) elapses or until the number of winning prizes to the variable winning device 53 reaches six (the number of low frequency).

  It should be noted that the number of opening / closing operations of the variable winning device 53 in the high-frequency winning mode and the low-frequency winning mode, the opening limit time (or opening limit period) for one opening, and the opening limit number for one opening are the same as those in the high-frequency winning mode. As long as the occurrence frequency of winning in the variable winning device 53 between the start and end of the opening / closing execution mode is higher than that in the low-frequency winning mode, the value is not limited to the above value. Is optional. Specifically, if the high frequency winning mode has a larger number of opening and closing times than the low frequency winning mode, the opening limit time for one opening is longer, or if the opening limit number for one opening is set to be larger. Good.

  However, in order to clarify the difference in privilege between the high-frequency winning mode and the low-frequency winning mode, in the opening / closing execution mode according to the low-frequency winning mode, the winning to the variable winning device 53 does not substantially occur. It may be configured. For example, in the high-frequency winning mode, the product of the launch period of the game ball and the open limit number is set shorter than the open limit time for one release, while in the low-frequency winning mode, It is good also as a structure which sets the product of the launching period of a game ball and the open limit number longer than open limit time. Also, even if the launch interval of the game balls and the opening time of one variable winning device 53 are not as described above, in the low frequency winning mode, by setting the latter to be shorter than the former, It is possible to easily realize a configuration in which a winning to the variable winning device 53 does not occur substantially.

  In addition, the low frequency support mode (low frequency support state or low frequency guide state) and the high frequency support mode (high frequency support state) are set so that the frequency at which the electric accessory 54a is opened per unit time is relatively high. Alternatively, a high frequency guide state) may be set.

  (22) In each of the above embodiments, the discharge gas 144 is sealed at a pressure lower than the atmospheric pressure. However, the present invention is not limited to this. For example, the discharge gas 144 is sealed at a pressure equal to or higher than the atmospheric pressure. It is good also as a structure. However, when the pressure is lower than the atmospheric pressure, discharge is more likely to occur in a situation where the same voltage is applied, and therefore, the configuration in which the discharge gas 144 is sealed at a lower pressure is better.

  (23) In each of the above embodiments, the adhesive is applied to the entire back surface of the conductive seal 180. However, the present invention is not limited to this. For example, the adhesive may be applied to a part of the back surface. In this case, since the resistance corresponding to the adhesive can be reduced, the function of guiding the discharge path by the conductive seal 180 is enhanced. However, if attention is paid to the difficulty of peeling off the conductive seal 180, a configuration in which an adhesive is applied to the entire back surface is preferable.

  (24) In each of the above embodiments, the brightness of the discharge light emission of the plasma lamp 120 is adjusted by providing the conductive seal 180 for inducing (aggregating) the discharge path and switching the conductive seal 180 between the floating state and the ground state. However, the present invention is not limited to this. For example, the luminance of discharge light emission of the plasma lamp 120 may be adjusted by controlling the AC voltage applied to the discharge electrode 150. In addition, as a structure which controls AC voltage, the structure shown to said (10) etc. can be considered, for example.

  (25) Other types of pachinko machines different from the above-described embodiment, such as pachinko machines in which an electric accessory is released a predetermined number of times when a game ball enters a specific area of a special device, or a game ball in a specific area of a special device The present invention can also be applied to a pachinko machine that generates a big hit when entering, a pachinko machine equipped with other objects, an arrangement ball machine, a sparrow ball, and the like.

  Also, a non-ball-type gaming machine, for example, a plurality of reels with a plurality of types of symbols attached in the circumferential direction, starts rotation of the reel by inserting a medal and operating a start lever, and a stop switch is operated. Or, if a specific symbol or a combination of specific symbols is established on an active line visible from the display window after the reel has stopped after a predetermined period of time, a privilege such as paying out medals is given to the player The present invention can also be applied to a slot machine.

  In addition, a pachinko machine and a slot machine that have a take-in device and start rotation of a reel by operating a start lever after a predetermined number of game balls stored in the storage unit are taken in by the take-in device The present invention can also be applied to a gaming machine in which is integrated.

<Invention Group Extracted from the Embodiments>
Hereinafter, the features of the invention group extracted from the above-described embodiments will be described while showing effects and the like as necessary. In the following, for easy understanding, the corresponding configuration in the above embodiment is appropriately shown in parentheses and the like, but is not limited to the specific configuration shown in parentheses and the like.

Features 1. It has a discharge vessel (plasma lamp 120) and a discharge electrode (discharge electrode 150) in which a discharge gas (discharge gas 144) enclosed can be visually recognized, and the discharge electrode with respect to the discharge electrode Plasma discharge means (plasma discharge apparatus 113) for emitting discharge in the discharge vessel when a voltage capable of ionizing the gas is applied,
Brightness adjusting means (conductive seal 180 and NPN transistor 381) for adjusting the brightness of discharge light emission of the plasma discharge means;
A gaming machine characterized by comprising:

  According to the feature 1, when a voltage is applied to the discharge electrode, the discharge gas sealed in the discharge vessel is ionized, and discharge light emission is performed in the discharge vessel. In this case, since the movement of the charged particles generated by the discharge is a random movement, the discharge path varies randomly. Thereby, a player's attention can be attracted compared with the light-emitting device with which the light emission mode was fixed. Therefore, the degree of attention to the game can be increased through the display effect by the plasma discharge means.

  In such a configuration, by adjusting the brightness of the discharge light emission of the plasma discharge means, the light emission mode of the discharge can be suitably viewed by the player. Thereby, the display effect by a plasma discharge means can be made to visually recognize suitably, and the attention degree to a game can be raised through the said display effect.

Feature 2. The brightness adjusting means includes
Guiding means (conductive seal 180) for guiding the discharge path;

The gaming machine according to Feature 1, further comprising:

  According to the feature 2, the light emission mode of the discharge can be changed by inducing the discharge path. The guidance can be released or relaxed by switching means. Thereby, the attention degree to a game can be raised through diversification of the light emission mode of discharge.

Feature 3. A pattern display means (seven-segment display device 112) for displaying a pattern;
Display mode determining means for determining the display mode to be displayed on the picture display means (function for executing the process of step S503 or step S514 in the MPU 321 variable command handling process);
Based on the display mode determined by the display mode determination unit, a switching control unit that performs switching control of the switching unit (function of executing the process of step S509, step S512, or step S515 in the MPU 321 variable command handling process) )When,
The gaming machine according to Feature 2, further comprising:

  According to the feature 3, by performing switching control of the switching unit based on the display mode displayed on the design display unit, the display mode displayed on the design display unit and the light emission mode of the discharge unit can be associated with each other. . Thereby, both can be provided to a player as one display effect.

Feature 4. The induction means includes an auxiliary electrode (conductive seal 180) capable of generating a potential difference with the discharge electrode,
The switching means switches between a potential difference generating state that causes the potential difference with the auxiliary electrode in the first state and a floating state as the second state. Gaming machine.

  According to the feature 4, when the auxiliary electrode is in a floating state, the discharge path is not easily induced. On the other hand, when the auxiliary electrode is in a potential difference generation state, the current easily flows between the discharge electrode and the auxiliary electrode. Therefore, the discharge path is easily induced. Therefore, the induction of the discharge path can be suitably performed.

Feature 5. The discharge electrode has a rod shape,
The discharge vessel has a spherical shape, and the discharge vessel is formed with a recess (electrode recess 152) into which the discharge electrode can be inserted by indenting a part thereof.
The discharge electrode is arranged in a state of being inserted into the recess,
The gaming machine according to claim 4, wherein the auxiliary electrode is arranged so as to guide the discharge path in a direction intersecting an axial direction of the discharge electrode.

  According to the feature 5, when a voltage is applied to the discharge electrode in a state where the rod-shaped discharge electrode is inserted into the concave portion formed in the spherical discharge container, the inside of the discharge electrode and the discharge container A discharge path is formed between the wall surface. In this case, since the discharge container has a spherical shape, the discharge path is easily formed radially around the discharge electrode. Thereby, the display effect of the discharge light emission of the aspect which spreads radially centering on the electrode for discharge can be made visible.

  Here, the discharge path is easily induced in the direction intersecting the axial direction by the auxiliary electrode. Thereby, the brightness | luminance of the said plasma discharge means when the plasma discharge means is seen from extension of the electrode for discharge can be improved.

  Feature 6 6. The gaming machine according to claim 5, wherein the auxiliary electrode is formed in an annular shape so as to surround the discharge vessel around the axis of the discharge electrode.

  According to the feature 6, since the auxiliary electrode is formed in an annular shape so as to surround the axis of the discharge electrode, the discharge path is formed in a direction intersecting the axial direction around the discharge electrode by induction by the auxiliary electrode. It becomes easy. Thereby, when the plasma discharge means is viewed from the extension of the discharge electrode, the entire discharge vessel looks bright. Therefore, when the plasma discharge means is viewed from the extension of the discharge electrode, it is possible to enlarge a region where discharge light emission can be seen.

  Feature 7. The gaming machine according to claim 6, wherein a conductive layer (conductive paint 191) is provided on an inner peripheral surface of the recess.

  According to the feature 7, when a voltage is applied to the discharge electrode, discharge easily occurs from the region where the conductive layer is formed on the inner wall surface of the recess. Since the conductive layer is formed on the inner peripheral surface of the recess, discharge is easily performed in a direction intersecting the axial direction, and the discharge path is easily trapped by the auxiliary electrode. Thereby, the induction function of the discharge path by an auxiliary electrode can be improved.

  Feature 8 The discharge electrode and the inner peripheral surface of the recess are electrically connected, and provided with connection means (steel wool 192) that is in contact with the inner peripheral surface of the recess at a plurality of locations. The gaming machine according to the feature 6 or the feature 7 characterized by the above.

  Since the discharge electrode is formed in a rod shape, when a voltage is applied to the discharge electrode, a non-uniform electric field is generated around the tip of the discharge electrode, and discharge is easily performed from the tip.

  On the other hand, according to this feature, since the discharge electrode and the inner peripheral surface of the recess are electrically connected via the connecting means, the connection is made when a voltage is applied to the discharge electrode. Discharge is easily performed from the contact point between the means and the inner peripheral surface of the recess. Since a plurality of the contacts are formed around the axis of the discharge electrode, the number of discharge paths formed is increased, and the arbitraryness of the discharge path is improved in the direction intersecting the axis direction. Thereby, the randomness of the discharge path can be improved within a range in which the discharge path is formed in a direction intersecting the axial direction. Therefore, it is possible to achieve both the aggregation of the discharge paths and the randomness of the discharge paths.

  According to the relationship with the feature 7, it is preferable that “the connecting means is in contact with the conductive layer at a plurality of locations”.

Feature 9 The connection means includes a cotton-like conductive material (steel wool 192) made of an aggregate of metal fibers,
The gaming machine according to claim 8, wherein the conductive material is sandwiched between the discharge electrode and an inner peripheral surface of the recess.

  According to the feature 9, the discharge electrode and the inner peripheral surface of the recess are electrically connected by sandwiching the cotton-like conductive material, and many contacts are formed between the conductive material and the inner peripheral surface of the recess. . Thereby, the multiple contact of the internal peripheral surface of a recessed part and a connection means is easily realizable.

Feature 10 The plasma discharge means includes a cover member (cover member 161) having an internal space (accommodation space 164) that can accommodate the discharge container,
The discharge vessel is housed in the cover member;
The gaming machine according to any one of features 4 to 9, wherein the auxiliary electrode is attached to the cover member.

  Generally, a discharge vessel may be formed of a relatively fragile material such as a glass tube from the viewpoint of heat resistance and insulation. For this reason, there exists a possibility that the discharge container may be destroyed by an external impact. On the other hand, according to this feature, since the discharge container is accommodated in the internal space of the cover member, it is possible to suppress destruction of the discharge container due to an external impact.

  Here, the auxiliary electrode is attached to the cover member. Thereby, since an auxiliary electrode can be attached from the outside of a plasma discharge means, the attachment work of an auxiliary electrode can be performed easily. Further, since it is not necessary to directly touch the discharge container when attaching the auxiliary electrode, it is possible to avoid the disadvantage that the discharge container is broken in the attaching operation.

Feature 11. The discharge electrode has a rod shape,
The discharge vessel has a spherical shape, and the discharge vessel is formed with a recess (electrode recess 152) into which the discharge electrode can be inserted by indenting a part thereof.
The discharge electrode is arranged in a state of being inserted into the recess,
The auxiliary electrode is a seal member (conductive seal 180) having an adhesive layer formed on one surface,
11. The gaming machine according to claim 10, wherein the seal member is attached to a specific portion around the axis of the discharge electrode in the cover member.

  According to the feature 11, when a voltage is applied to the discharge electrode in a state where the rod-shaped discharge electrode is inserted into the recess formed in the spherical discharge container, the tip of the discharge electrode and the discharge electrode A discharge path is formed between the inner wall surface of the container. In this case, since the discharge container has a spherical shape, the discharge path is easily formed radially around the discharge electrode. Thereby, the display effect of the discharge light emission of the aspect which spreads radially centering on the electrode for discharge can be made visible.

  Here, since the sealing member as the auxiliary electrode is attached to a specific portion around the axis of the discharge electrode, the discharge path is easily guided by the auxiliary electrode in a direction intersecting the axial direction. Thereby, the brightness of the plasma discharge means when the plasma discharge means is viewed from the extension of the discharge electrode can be improved.

  Further, for example, by sticking a seal member to a place that is not noticeable when the plasma discharge means is viewed from the extension of the discharge electrode as a specific place, the seal member is less likely to become an obstacle when performing a display effect of discharge light emission. be able to. Therefore, inconveniences that can be caused by providing the auxiliary electrode can be avoided.

  Furthermore, since the auxiliary electrode is a seal member, the auxiliary electrode can be easily attached. Thereby, the fall of workability | operativity which may arise by attaching an auxiliary electrode can be suppressed.

Feature 12. The cover member is
A cylindrical portion (cover side cylindrical portion 162) that is formed in a cylindrical shape and whose inner diameter is set equal to or larger than the outer diameter of the discharge vessel;
A hemispherical shell part (hemispherical shell part 163) which is continuous with one end of the cylindrical part and is formed in a substantially hemispherical shell shape corresponding to the spherical shape of the discharge vessel;
With
The internal space is a space defined by the cylindrical portion and the hemispherical shell portion, and is open via the other end portion of the cylindrical portion,
The discharge electrode is disposed such that the base end side is disposed on the other end side of the cylindrical portion and the distal end portion faces the hemispherical shell side in the axial direction of the cylindrical portion,
The gaming machine according to claim 11, wherein the sealing member is attached to an outer peripheral surface of the cylindrical portion as the specific portion.

  For example, in the situation where the cover member is formed in a spherical shape, when a seal member is attached around the axis of the outer peripheral surface, when the plasma discharge means is viewed from the extension of the discharge electrode, the seal member has an inner diameter and an outer diameter. The sealing member tends to be an obstacle when the display effect of the discharge light emission is visually recognized. In particular, the larger the length dimension of the seal member in the axial direction, the more easily the seal member gets in the way. However, when the length is reduced, the sealing member is easily peeled off and the discharge path induction function is lowered.

  On the other hand, according to this feature, since the seal member is attached to the outer peripheral surface of the cylindrical portion whose axial direction is the same as that of the discharge electrode, the plasma discharge means is connected to the plasma discharge from the extension of the discharge electrode. When the means is viewed, the seal member looks linear. In this case, since the ratio of the seal member to the area where discharge light emission is performed is smaller than that in the case where the seal member is attached to the spherical surface, the seal member is less noticeable. As a result, it is possible to avoid the inconvenience that it becomes difficult to see the display effect of the discharge light emission because the seal member becomes an obstacle.

  Further, according to such a configuration, even when the length dimension is increased, there is no change in appearance when the plasma discharge means is viewed from the extension of the discharge electrode. The length dimension can be set without considering that the member gets in the way. Thereby, the said effect can be acquired, ensuring the function which attaches a sealing member suitably, and the function which exhibits the guidance function of the said sealing member suitably.

Feature 13. The sealing member has light shielding properties;
13. The length dimension of the seal member in the axial direction is set so that at least a part of the discharge electrode is disposed in a region surrounded by the seal member. Game machines.

  According to the feature 13, since at least a part of the discharge electrode is surrounded by the light-shielding seal member, the portion where the discharge paths are gathered is covered with the seal member. This makes it easier to see the light emission mode of discharge when the plasma discharge means is viewed from the extension of the discharge electrode.

Feature 14. A pattern display means (seven-segment display device 112) for displaying a pattern;
A visual recognition unit (display unit 61) provided on the front surface of the gaming machine;

  According to the feature 14, it is possible to visually recognize the pattern by the pattern display unit or to visually recognize the discharge light emission mode of the plasma discharge unit through the same viewing unit. Thereby, it is possible to provide a player with a novel display effect as compared with the configuration in which the picture display means and the plasma discharge means are simply provided.

  In particular, the display form of the picture display means for displaying a picture is completely different from the display form of the plasma discharge means, and therefore it is possible to make the display effect more innovative by mixing them. Thereby, the attention degree to a game can be raised.

  Further, for example, it is possible to display the pattern displayed by the pattern display means and the light emission mode of discharge of the plasma discharge means in an overlapping manner. Thereby, diversification of display effects can be achieved.

Feature 15. The plasma discharge means is arranged above or below the mirror member, while the picture display means is arranged behind the mirror member,
The mirror member is inclined with respect to the visual recognition portion so that the reflected light of the light incident from the plasma discharge means side is in the same direction as the transmitted light of the light incident from the picture display means side. 15. A gaming machine according to the feature 14, characterized by.

  According to the feature 15, when the intensity of light incident from the visual recognition part side is larger than the intensity of light transmitted from the picture display means side, the mirror member functions like a mirror. In this case, the plasma discharge means is projected on the mirror member, and the discharge light emission of the plasma discharge means can be visually recognized through the visual recognition part.

  On the other hand, when the intensity of the light transmitted from the pattern display means side is larger than the intensity of the light incident from the viewing part side, the light from the pattern display means side becomes visible through the viewing part, and the pattern display means is visually recognized. can do. On the other hand, when discharge light emission is performed by the plasma discharge means in such a situation, the light emission can be visually recognized. From the above, in order to visually recognize the transmitted light, it is necessary to make the emission intensity larger than the intensity of the light from the visual recognition side, unlike the case of using the reflected light.

  Here, since the intensity of the discharge light emission of the plasma discharge means is relatively small, it is difficult to make the intensity of the discharge light emission larger than the light intensity from the viewing portion side. On the other hand, according to the present feature, the pattern display means may be disposed behind the mirror member that requires a relatively high light intensity, and the plasma discharge means may be a mirror member that has a relatively low light intensity. Therefore, it is possible to display a pattern while suitably visualizing discharge light emission with a relatively low light intensity.

  In particular, when the pattern displayed by the pattern display unit and the light emission mode of discharge of the plasma discharge unit are displayed in an overlapping manner, both can be visually recognized in an easy-to-view mode.

  Feature 16. An opening / closing means (opening / closing shutter 221) capable of switching between an open state in which light emission by the plasma discharge means is visually recognized and a closed state in which part or all of the light emission is not visually recognized is provided. The gaming machine according to any one of the above.

  Noise occurs at the start timing of discharge light emission by the plasma discharge means. The noise is larger than that during the discharge light emission period. Here, according to the present feature, switching between the state in which the light emission mode of discharge is visually recognized and the state in which it is not visually recognized is realized by operating the opening / closing means, and thus it is not necessary to perform on / off control of discharge light emission. Thereby, the malfunction which may arise by the noise in the start timing of discharge light emission can be suppressed.

  Even if the discharge light emission of the plasma discharge means is not performed, the plasma discharge means may be visible depending on how light is inserted from the surroundings. On the other hand, according to this feature, the plasma discharge means can be made invisible by closing the opening / closing means when the display effect of discharge luminescence is not performed. Thereby, the said inconvenience can be avoided.

Feature 17. A pattern display means (seven-segment display device 112) for displaying a pattern;

  According to the feature 17, it is possible to visually recognize a pattern by the pattern display unit or to visually recognize a discharge light emission mode of the plasma discharge unit through the same viewing unit. Thereby, it is possible to provide a player with a novel display effect as compared with the configuration in which the picture display means and the plasma discharge means are simply provided.

  In particular, the display form of the picture display means for displaying a picture is completely different from the display form of the plasma discharge means, and therefore it is possible to make the display effect more innovative by mixing them. Thereby, the attention degree to a game can be raised.

  Further, for example, it is possible to display the pattern displayed by the pattern display means and the light emission mode of discharge of the plasma discharge means in an overlapping manner. Thereby, diversification of display effects can be achieved.

  Here, the opening / closing means is arranged on the optical path of light from the plasma discharge means to the visual recognition part, while the opening / closing means is not arranged on the optical path of light from the picture display means to the visual recognition part. Thereby, the light from the pattern display means to the visual recognition part is not easily obstructed by the opening / closing means. Therefore, even when the opening / closing means is in the closed state, the design of the design display means can be viewed through the visual recognition unit. Therefore, it is possible to avoid the inconvenience that the opening / closing means becomes an obstacle when displaying the pattern.

Feature 18. A pattern display means (seven-segment display device 112) for displaying a pattern;

  According to the feature 19, the game control means is a DC drive, and the power supply means is set so as to supply a DC voltage correspondingly. On the other hand, since the plasma discharge means is AC driven, the DC voltage supplied from the power supply means cannot be used as it is.

  On the other hand, in this feature, a discharge power supply means is provided separately from the power supply means, and a specific AC voltage is applied from the discharge power supply means. Thereby, it is possible to provide an AC drive plasma discharge means in a DC drive game machine. Therefore, the plasma discharge means can be attached while minimizing the change of the game control means of the existing gaming machine.

The gaming machine according to the feature 19, characterized by comprising:

  According to the feature 20, the specific AC voltage can be generated using the DC voltage supplied from the power supply unit via the game control unit. Thereby, since it is not necessary to provide a special structure for the game control means and the power supply means, the plasma discharge means can be suitably attached to the existing game machine.

  Further, since the converted AC voltage is boosted, the configuration related to boosting can be simplified compared to the configuration of boosting the DC voltage. Thereby, through simplification of the configuration for mounting the plasma discharge means on the gaming machine, an increase in cost that may occur when the plasma discharge means is mounted on the gaming machine can be suppressed.

Feature 21. In addition to the plasma discharge means, an effect device (speaker unit 26 and the like) used when performing an effect related to a game is provided,

  According to the feature 21, the discharge power supply means operates when a DC voltage is supplied from the second control means. In this case, since there is no need to change the existing control system, changes to the existing gaming machine can be reduced. Thereby, a plasma discharge means can be suitably mounted with respect to the existing game machine.

  Further, the discharge power supply means operates based on the supply of the DC voltage from the second control means, and discharge by the plasma discharge means is performed. Since the said 2nd control means performs control using a production | presentation apparatus, it becomes possible to perform the production | presentation which linked | related the plasma discharge means and the production | presentation apparatus, and can attain diversification of production.

  In particular, since the second control means and the discharge power supply means are arranged at positions separated from each other, noise generated from the discharge power supply means hardly affects the second control means. Therefore, the malfunction of the 2nd control means which may arise by providing the power supply means for discharge can be suppressed.

  Feature 22. The game according to any one of claims 19 to 21, wherein the discharge power supply means includes frequency changing means (variable capacitor 401 and switching drive unit 402) for changing the frequency of the specific AC voltage. Machine.

  According to the feature 22, since the frequency of the specific AC voltage can be changed, the luminance of the discharge can be controlled by changing the frequency. Thereby, the degree of attention to the display effect by the plasma discharge means can be increased by increasing the luminance due to the discharge at a predetermined timing.

  In addition, for example, by reducing the frequency in a situation where no game is played, it is possible to suppress discharge and to suppress heat generated by the discharge. Thereby, the display effect by the plasma discharge means can be suitably performed in a situation where a game is being performed while avoiding the disadvantage that the discharge vessel is damaged by the heat.

In this case, since the discharge path varies randomly, it is possible to attract the player's attention as compared with the light emitting device in which the light emitting mode is fixed. Therefore, the degree of attention to the game can be increased through the display effect by the plasma discharge means. However, the overall luminance is reduced due to the randomness of the light emission mode.

  On the other hand, according to this feature, since the auxiliary electrode is provided, the discharge path is easily concentrated between the discharge electrode and the portion corresponding to the auxiliary electrode. Therefore, it seems that the brightness of the plasma discharge means is increased, and the light emission mode is easily seen. Therefore, the light emission mode of discharge can be suitably displayed, and the degree of attention to the game can be increased through the display.

  Further, by providing the auxiliary electrode, it is possible to make the discharge path less susceptible to the influence of the electronic device when the plasma discharge means is installed around the electronic device provided in the gaming machine.
