  However, in the conventional gaming machine, the operation member protrudes laterally. There is a problem that parts such as a connector hanging from the game island side interfere with the protruding portion, and the operation member is damaged.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a gaming machine that can easily and smoothly perform a game ball removal operation without damaging the switching member, and thus improve the work efficiency of the game ball removal operation. To do.

According to the first aspect of the present invention, there is provided a prize ball tank that stores game balls, a payout device that supplies game balls to a prize ball tray, and a game ball that is provided in a casing and stored in the prize ball tank. A payout passage that leads to the payout device, a ball removal passage that is provided inside the casing and discharges the game balls stored in the prize ball tank without being led to the payout device, and a ball passage that is provided in the casing and passes through the prize ball tank. A switching member that distributes the stored game balls to either the payout passage or the ball withdrawal passage, wherein the switching member includes a first rotation stop position and a second rotation stop position. The game balls stored in the prize ball tank at the first rotation stop position are provided so as to be rotatable about the rotation shaft provided in the casing so as to be reciprocally movable. Led to the payout passage, the second time In the prize ball tank game ball that is stored in the at rest position and the ball抜通path guided switching valve, is provided so as to linearly move in the vertical direction inside the casing, and stopped above the stop position condition Engage with the switching valve, stop the switching valve at the first rotation stop position, move from the upper stop position to the lower stop position along the linear direction, and release the engagement state with the switching valve by the operation member to allow the axis of rotation of the rotating shaft from the first rotation stop position of the switching valve toward the second rotation stop position, the upper stop position the operating member And an urging member that urges the directional member toward the direction, and the switching valve is an inclined piece that guides the game ball to the payout passage when the switching valve is located at the first rotation stop position. And the switching valve is located at the first rotation stop position. An engagement piece to be engaged with said operating member is stopped at the upper stop position can, the changeover valve under gravity when the engagement state between the engagement piece and said operating member is eliminated A center-of-gravity eccentric portion that rotates around the axis of the rotation shaft from the first rotation stop position toward the second rotation stop position; and a groove portion that is formed on the center-of-gravity eccentric portion and engages with the operation member. The inclined piece and the engaging piece are located inside the casing when the switching valve is located at the first rotation stop position, and the operating member is When the switching valve is located at the first rotation stop position and the second rotation stop position, the switching valve is located inside the casing, and the switching valve is at the first rotation stop position and the operation is performed. When the member is biased to the upper stop position by the biasing member, the operation unit The material and the switching valve are engaged, the inner surface of the operating member is in a state of preventing the switching valve from rotating, and the inner surface of the operating member from the state of preventing the switching valve from rotating. When the operating member is pressed and the operating member is moved from the upper stop position to the lower stop position, the engagement state between the switching valve and the operating member is released, and the switching valve is moved around the rotation axis. When the operation member rotates to reach the second rotation stop position and the pressing of the operation member is released, the operation member moves upward so that the operation member and the groove portion are engaged with each other. The operation member is pressed from a state where the member and the groove are engaged, and moved to the lower stop position to release the engagement between the operation member and the groove, and the switching valve is pushed into the casing. The switching valve is stopped by the first rotation When the pressing of the operating member is released, the operating member is biased to the upper stop position, the operating member and the switching valve are engaged, and the inner surface of the operating member is the switching valve It is in a state that prevents the rotation .

  According to the first aspect of the present invention, when the switching valve is stopped at the first rotation stop position, the game ball is guided to the payout passage and is stopped at the second rotation stop position. The game ball is guided to the ball passage. Here, in a state where the operation member is stopped at the movement stop position, the switching valve stops at the first rotation stop position. When the operation member linearly moves in a direction away from the movement stop position, the switching valve can be rotated about the rotation axis from the first rotation stop position toward the second rotation stop position. In this way, each rotation stop position of the switching valve is easily switched by only a linear movement operation of the operation member, so that the ball removal operation for guiding the game ball to the ball extraction passage becomes easy and smooth, and the work efficiency is improved. Can be increased.

  In particular, the inclined piece and the engaging piece of the switching valve are located inside the casing when the switching valve is located at the first rotation stop position. The operation member is located inside the casing when the switching valve is located at the first rotation stop position and the second rotation stop position. Thereby, when the switching valve is located at the first rotation stop position, the inclined piece, the engaging piece, and the operation member of the switching valve do not protrude outside the casing, and the switching valve is The operation member does not protrude outside the casing when it is positioned at the 2 rotation stop position. As a result, there is no interference between the inclined piece and the engaging piece of the switching valve, and parts such as a connector hanging from the game island side with respect to the operation member, and damage to the switching valve and the operation member can be prevented in advance. .

The switching valve rotates from the first rotation stop position to the second rotation stop position when the eccentric state of the center of gravity receives gravity when the engagement state between the operation member and the engagement piece is released. It rotates around the axis of the moving shaft. As a result, when the engagement state between the operation member and the engagement piece is canceled, the switching valve automatically reaches the second rotation stop position and easily guides the game ball to the ball extraction passage. be able to.

Further , the operation member is urged toward the movement stop position by the urging member. The operating member is pressed against the engaging portion by the urging force of the urging member in a state where the switching valve is stopped at the second rotation stop position, and is engaged with the engaging portion. In this way, the switching valve is engaged with the operation member pressed by the engaging portion by the urging force of the urging member, and the state stopped at the second rotation stop position of the switching valve is maintained. Here, since the operating member and the engaging portion are firmly engaged by the urging force of the urging member, even when the attitude or orientation of the gaming machine changes, the operating member and the engaging portion are engaged. The condition is not easily resolved. As a result, the ball removal work of the game ball can be executed reliably, and the work efficiency can be stabilized at a high level.

  Next, a gaming machine according to the first embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a configuration in which the present invention is applied to a pachinko machine that is an example of a ball game machine will be described.

The inner frame 14 is entirely made of plastic and is pivotally supported so as to be openable and closable with respect to the outer frame 12. A locking device 22 is provided slightly below the center of the right end of the inner frame 14.

  The front frame 16 is a specific example of the front door of the present invention, occupies about 2/3 of the entire front portion of the pachinko machine 10, and is pivotally supported at the left end of the inner frame 14 so that it can be opened and closed. Has been. The front frame 16 is entirely made of plastic, and corresponds to the shape of the game area 28 (see FIG. 3) formed on the game board 26 so that the game board 26 (see FIG. 3) can be seen from the front. It has an opening 30 formed in a substantially circular shape. A glass plate 32 is attached to the back surface of the front frame 16 by a glass frame (not shown). Then, based on the player, the game area 28 formed on the game board 26 is positioned behind the glass plate 32.

  Further, an upper plate portion 18 is provided below the front frame 16. The upper plate portion 18 is provided with a production button 40 and a ball lending operation portion 155.

  The ball lending operation unit 155 is provided with a ball lending switch 156 for requesting ball lending and a return switch 158 for requesting the return of the prepaid card inserted into the card insertion slot 157, respectively. Yes.

  A lower dish portion 20 is provided below the upper dish portion 18. A launching handle 24 for launching a game ball is provided on the lower right side of the lower plate part 20. The firing handle 24 is provided with a firing lever 44 and a firing stop button 46, respectively.

  Further, sub-speakers 48 for outputting predetermined sound effects are respectively provided on the lower left and right sides of the lower plate part 20.

  As shown in FIG. 2, the inner frame 14 is pivotally supported at the left end of the outer frame 12 so that it can be opened and closed. For this reason, the front door 16 has a configuration that can be opened and closed with respect to the inner frame 14 and the outer frame 12, and the inner frame 14 has a configuration that can be opened and closed with respect to the outer frame 12. An opening (not shown) for attaching the game board 26 is formed on the inner side surface of the inner frame 14. Thereby, the player can visually recognize the game area 28 of the game board 26 through the opening 30 of the front frame 16 with the game board 26 attached to the opening.

  As shown in FIGS. 2 and 4, a prize ball tank 200 for storing game balls is provided at the upper part on the back side (back side) side of the inner frame 14. The prize ball tank 200 is connected to a game ball management device (not shown) provided in an island facility such as a pachinko hall, and a game ball from the game ball management device toward the prize ball tank 200 as necessary. Is supplied. A predetermined number of game balls are stored in the prize ball tank 200.

  Connected to the bottom of the prize ball tank 200 is one end of a guide path 202 for guiding a game ball inside the prize ball tank 200 to a ball vent valve (switching valve, switching member) 212 described later. At the other end of the guide path 202, a game ball sorting unit 208 that distributes game balls to either the payout passage 204 or the ball withdrawal passage 206 is provided. The game ball distribution unit 208 is a space that is formed in a curved shape as a whole and extends in the vertical direction (gravity direction (vertical direction)). The game ball distribution unit 208 is connected to a payout passage 204 for guiding the game ball to a payout device 161 described later. The payout device 161 discharges a predetermined number of game balls to the upper plate 18 (or the lower plate 20 depending on the configuration of the pachinko machine) based on control signals from the main control board 102 and the payout control board 104. To do.

  Further, a part of the game ball sorting unit 208 is connected with a ball extraction passage 206 that discharges the game ball to the outside without guiding it to the payout device 161. The ball removal passage 206 is a passage through which a game ball that has fallen freely from the guide path 202 enters the game ball distribution unit 208 as it is without the ball removal valve 212 closing the inlet.

  Here, the game ball sorting portion 208, the payout passage 204, and the ball removal passage 206 are partitioned in the casing 203 attached to the back surface (back surface) side of the inner frame 14. For this reason, since it is interrupted by the casing 203, it is impossible to directly contact the game ball sorting unit 208, the payout passage 204, and the ball withdrawal passage 206 from the outside (preventing fraud).

  As shown in FIGS. 4 and 5, the casing 203 is provided with a distribution device (switching member) 210 for distributing game balls to the payout passage 204 or the ball removal passage 206. The sorting device 210 is provided in the vicinity of the game ball sorting unit 208. The sorting device 210 includes a ball release valve 212 and a slide member (operation member, switching member) 214.

  As shown in FIGS. 6 and 7, the ball removal valve 212 includes a rotating shaft 216, an inclined piece 218 connected to the rotating shaft 216, and a predetermined angle with the inclined piece 218 connected to the rotating shaft 216. The open engagement piece 220 includes a center-of-gravity eccentric portion 222 formed so as to straddle between the inclined piece 218 and the engagement piece 220.

  The rotation shaft 212 is provided on the side wall of the casing 203 so as to be rotatable around its own axis.

  The inclined piece 218 is formed in a flat plate shape as a whole. When the ball release valve 212 is in the first rotation stop position (the state shown in FIGS. 6, 11, and 12, the same applies hereinafter), The game ball that has dropped and passed through the game ball sorting unit 208 is caused to collide and be guided to the payout passage 204. The inclined piece 218 acts to close the inlet of the ball removal passage 206 when the ball removal valve 212 is in the first rotation stop position.

  Here, the inclined piece 218 is disposed inside the casing 203 when the ball removal valve 212 is in the first rotation stop position and the second rotation stop position (states shown in FIGS. 7, 14, and 15; the same applies hereinafter). Is located. In other words, the inclined piece 218 is not configured to protrude outside the casing 203 (for example, the right side) when the ball removal valve 212 is in the first rotation stop position and the second rotation stop position. . As described above, the inclined piece 218 is always located inside the casing 203. As a result, parts such as a connector hanging from the island side of the pachinko machine do not interfere with the inclined piece 218, and damage to the inclined piece 218 can be prevented in advance.

  The engagement piece 220 is formed in a flat plate shape as a whole. When the ball release valve 212 is in the first rotation stop position, the engagement piece 220 is engaged with the upper end of the slide member 214, and the ball release valve 212 is in the first rotation. This maintains the state at the moving stop position. The engagement piece 220 is formed at the engagement piece main body 220A formed in a flat plate shape and the tip of the engagement piece main body 220A, and above the slide member 214 when the ball release valve 212 is in the first rotation stop position. The claw portion 220B that engages with the end, the upper end surface of the slide member 214 and the upper end surface of the slide member 214 in a state of being engaged with the slide member 214 formed so as to protrude downward from the distal end portion of the engagement piece main body 220A. And a positioning portion 220C in contact therewith. When the ball release valve 212 is in the first rotation stop position, the inner surface of the slide member 214 is in surface contact with the claw portion 220B, and the upper end surface of the slide member 214 is in surface contact with the lower end surface 221 of the positioning portion 220C. ing. In particular, when the inner surface of the slide member 214 comes into surface contact with the claw portion 220B, the ball release valve 212 is subjected to the center-of-gravity eccentricity action by the center-of-gravity eccentric portion 222, and is thus shifted from the first rotation stop position to the second rotation stop position side. Rotation toward is prevented. Further, the slide member 214 is pressed by the elastic force of a spring member (biasing member) 226 (see FIG. 12) described later when the upper end surface of the slide member 214 is in surface contact with the lower end surface 221 of the positioning portion 220C. 214 is positioned at the upper stop position. Thus, in a state where the ball removal valve 212 is located at the first rotation stop position, the ball removal valve 212 is firmly engaged with the slide member 214 at the claw portion 220B and the positioning portion 220C of the engagement piece 220. It has become.

  Here, the engagement piece 220 is located inside the casing 203 when the ball valve 212 is in the first rotation stop position. In other words, the engagement piece 220 is not configured to protrude to the outside (for example, the right side) of the casing 203 when the ball release valve 212 is in the first rotation stop position. Thus, the engagement piece 220 is located inside the casing 203 when the ball removal valve 212 is in the first rotation stop position. As a result, when the ball release valve 212 is at the first rotation stop position, the engagement piece 220 does not interfere with the engagement piece 220 and other components such as a connector hanging from the island side of the pachinko machine. Can be prevented in advance.

  The center-of-gravity eccentric part 222 is a weight part formed so as to straddle between the inclined piece 218 and the engagement piece 220, and functions to decenter the position of the center of gravity of the entire ball relief valve 212. In other words, the ball outlet valve is not provided with an eccentric portion of the center of gravity, and the ball outlet valve is configured to be a The valve withdrawal does not attempt to rotate from the first rotation stop position toward the second rotation stop position. On the other hand, as in this embodiment, the ball outlet valve 212 is provided with a center of gravity eccentric portion 222, and the ball outlet valve 212 includes a rotating shaft 216, an inclined piece 218, an engagement piece 220, and a center of gravity eccentric portion 222. , The position of the center of gravity of the entire ball removal valve 212 configured by is eccentric (displaced). For this reason, the ball removal valve 212 tends to rotate naturally from the first rotation stop position toward the second rotation stop position by the action of its own weight (the center of gravity eccentricity action by the center of gravity eccentricity 222). As described above, the center-of-gravity eccentricity 222 functions to decenter the position of the center of gravity of the entire ball extraction valve 212 in order to cause the ball extraction valve 212 to naturally rotate from the first rotation stop position toward the second rotation stop position. Have

  Here, the center-of-gravity eccentric portion 222 is located inside the casing 203 when the ball removal valve 212 is in the first rotation stop position. In other words, the center-of-gravity eccentric portion 222 is not configured to protrude to the outside (for example, the right side) of the casing 203 when the ball removal valve 212 is in the first rotation stop position. Thus, the center-of-gravity eccentric portion 222 is located inside the casing 203 when the ball removal valve 212 is in the first rotation stop position. As a result, when the ball release valve 212 is in the first rotation stop position, the center of gravity eccentric part 222 does not interfere with the center of gravity eccentric part 222, such as a connector hanging from the island side of the pachinko machine. Can be prevented in advance.

  The center-of-gravity eccentric part 222 is formed with a groove part (engagement part) 222A with which the slide member 214 is engaged. That is, in a state where the ball removal valve 212 is located at the second rotation stop position, the groove 222A of the gravity center eccentric portion 222 and the upper end of the slide member 214 are engaged. Here, since an elastic force is applied to the slide member 214 by the spring member 226 (see FIG. 12), the end surface of the slide member 214 presses the groove 222A from the lower side to the upper side with a predetermined pressure. Thereby, in a state where the ball removal valve 212 is positioned at the second rotation stop position, the ball removal valve 212 is in a state of being firmly engaged with the slide member 214 in the groove portion 222A of the gravity center eccentric portion 222.

  The center-of-gravity eccentric part 222 includes a curved piece 222B that curves downward. The curved piece 222B is a part that can come into contact with the upper end surface of the slide member 214 when the ball removal valve 212 is located at the second rotation stop position. By providing the curved piece 222B in the center-of-gravity eccentric portion 222, the engaging piece 220 of the ball release valve 212 is pushed inside the game ball sorting portion 208 when the ball release valve 212 is located at the second rotation stop position. Then, the curved piece 222B presses the upper end surface of the slide member 214 downward to push the slide member 214 downward. Then, as the curved piece 222B slides on the upper end surface of the slide member 214, the ball valve 212 can be rotated from the second rotation stop position side to the first rotation stop position side. As described above, when the ball release valve 212 is located at the second rotation stop position, the engagement piece 220 of the ball release valve 212 is moved to the inside of the game ball distribution unit 208 without pushing down the slide member 214 downward. It is possible to move the ball removal valve 212 to the first rotation stop position simply by pushing it into.

  The slide member 214 is provided so as to be linearly movable (linear motion) in the vertical direction (gravity direction (vertical direction)) in accordance with a pressing operation by a hall-related person or an administrator. A storage room 224 for retractably storing the slide member 214 is formed in a part of the side wall of the casing portion 203 and in the vicinity of the entrance of the ball extraction passage 206. In the storage room 224, the slide member 214 is stored so as to be movable in the vertical direction (gravity direction (vertical direction)). The storage room 224 is provided with a spring member 226 (see FIG. 12) for applying pressure to the slide member 214 toward the upper side. For this reason, the slide member 214 is always pressed upward by the elastic force of the spring member 226 (see FIG. 12), and the ball release valve 212 is in the first rotation stop position. The mechanical state is established in which the slide member 214 presses the engagement piece 220 (more specifically, the lower end surface 221 of the positioning portion 220C) of the ball release valve 212 upward at the upper stop position. When the slide member 214 is moved downward from the upper stop position, the spring member 226 (see FIG. 12) is compressed and deformed (contracted) and pressed so as to oppose the elastic force of the spring member 226. It is realized by.

  In addition, a protrusion 214A is formed on the surface of the slide member 214 so as to facilitate the pressing operation. For this reason, the hall-related person or manager presses the protruding portion 214A and pushes the slide member 214 downward, so that the downward movement of the slide member 214 becomes easy and smooth.

  Here, since the slide member 214 is housed in the housing room 224 and linearly moves along the vertical direction, the ball removal valve 212 is in the first rotation stop position and the second rotation stop position. In addition, it is located inside the casing 203. In other words, the slide member 214 is configured to protrude greatly to the outside (for example, the right side) of the casing 203 when the ball release valve 212 is in the first rotation stop position and the second rotation stop position. Absent. Further, since the slide member 214 is configured to linearly move along the vertical direction, the slide member 214 does not protrude outside the casing 203 when the slide member 214 moves linearly. Thus, the slide member 214 is always located inside the casing 203. As a result, parts such as connectors hung from the island side of the pachinko machine do not interfere with the slide member 214, and damage to the slide member 214 can be prevented. Further, even when the moving distance in the vertical direction of the slide member 214 is shortened, the ball valve 212 can be rotated. As a result, the slide member 214 can be prevented from being damaged due to the collision between the slide member 214 and external parts, and the ball release valve 212 can be reliably rotated.

  When the slide member 214 moves to the maximum in the downward direction, it stops at the downward stop position. When the slide member 214 is stopped at the lower stop position, the engagement state between the slide member 214 and the claw portion 220B and the positioning portion 220C of the ball release valve 212 is canceled. Accordingly, the ball valve 212 can be rotated about the rotation shaft 216 from the first rotation stop position toward the second rotation stop position under the action of gravity by the gravity center eccentric portion 222. become.

  When the ball removal valve 212 receives the action of gravity by the gravity center eccentric portion 222 and rotates around the rotation shaft 216 from the first rotation stop position to the second rotation stop position, the ball release valve 212 is finally obtained. Reaches the second rotation stop position. In a state where the ball removal valve 212 has reached the second rotation stop position, the inclined piece 218 of the ball removal valve 212 opens the inlet of the ball removal passage 206. As a result, the game ball that has rolled down the guide path 202 is free to fall vertically downward from the guide path 202 under the action of gravity. Therefore, in a state where the entrance of the ball removal passage 206 is open, the game ball enters the ball removal passage 206 from the game ball distribution portion 208 without entering the payout passage 204 from the game ball distribution portion 208. Will do.

  When the pressing force against the slide member 214 is released in a state where the ball release valve 212 has reached the second rotation stop position, the slide member 214 moves upward due to the elastic force of the spring member 226 (see FIG. 12). The slide member 214 engages with the gravity center eccentric part 222 of the ball extraction valve 212 in a groove 222A formed in the gravity center eccentric part 222 of the ball extraction valve 212. At this time, since a predetermined pressure is applied from the lower side to the upper side from the slide member 214 to the groove portion 222A of the gravity center eccentric portion 222, the engagement state between the slide member 214 and the gravity center eccentric portion 222 of the ball valve 212 is changed. Become stronger.

  In the present embodiment, the configuration in which the slide member 214 linearly moves along the vertical direction (gravity direction) is illustrated, but the present invention is not limited to this configuration. For example, the slide member 214 is linear along the left-right direction. You may move. That is, the slide member 214 is engaged with the claw portion 220B of the engagement piece 220 of the ball release valve 212 at the first rotation stop position at one stop position to position the ball release valve 212 at the first rotation stop position. If it is configured to engage the groove 222A of the eccentric portion 222 of the center of gravity of the ball release valve 212 at the second rotation stop position at the other stop position, the ball release valve 212 can be positioned at the second rotation stop position. The moving direction of the slide member 214 is not limited.

  Further, as shown in FIG. 1, a ball lending device 154 is provided on the front left side of the pachinko machine 10. In this embodiment, a CR unit is applied as the ball lending device 154. The ball lending device 154 is formed with a card insertion slot 157 for inserting a prepaid card. In addition, the structure which provided the cash unit as the ball lending apparatus 154 may be sufficient. In this cash unit, instead of the card insertion slot 157, a cash insertion slot (not shown) for inserting cash is formed.

  For example, when a prepaid card is inserted into the card insertion slot 157 of the ball lending device 154, the stored information of the prepaid card is read by a card reader / writer inside the ball lending device 154. When the remaining frequency of the prepaid card is “0”, the prepaid card is automatically returned from the card insertion slot 157. On the other hand, when the remaining frequency of the prepaid card is not “0”, when the ball lending switch 156 is pressed, the remaining frequency of the prepaid card is subtracted by the card reader / writer and the stored information of the prepaid card is rewritten. The number corresponding to the frequency (rented amount) is drawn, and the game ball (lending ball) is guided from the payout device 161 to the upper plate part 18. At this time, for example, when the remaining frequency of the prepaid card is subtracted to “0”, the prepaid card is automatically returned from the card insertion slot 157.

  In the configuration using a cash unit as the ball lending device 154, cash is counted by a cash counter inside the ball lending device when cash is inserted into the cash slot of the ball lending device. When the ball-lending switch is pressed after the amount of money reaches the predetermined amount, the cash amount is reduced by the cash counter and the number corresponding to the reduced amount (loan amount) is drawn. A ball (rented ball) is guided from the dispensing device 161 to the upper plate 18.

  Next, the surface structure of the game board 26 will be described.

  As shown in FIGS. 2 and 3, the game board 26 is held by the inner frame 14, and its back side is covered by the back mechanism board. In the game board 26, a substantially circular game area 28 is formed by an outer rail 50 and an inner rail 52 provided on the surface of the game board 26. Inside the game area 28, a start port 56B, a center accessory 64, a warp entrance 58, a number of obstacle nails 60, and the like are mainly disposed.

  The center accessory 64 is disposed at a substantially central portion of the game area 28 and mainly includes an effect symbol display device (symbol display device) 62 and lamps 66.

  The effect symbol display device 62 is display-controlled based on control signals from the main control board 102 (see FIG. 8) and the sub control board 106 (see FIG. 8), and has a substantially rectangular display surface (display area) 62A. have. On the display surface 62A, special design effects are displayed. Specifically, on the display surface 62A of the effect symbol display device 62, there is formed an effect symbol display area in which one or a plurality of effect symbols are displayed while changing one after another in a predetermined direction and then stopped. . That is, the left effect symbol display area for displaying the left effect symbol, the center effect symbol display area for displaying the center effect symbol, and the right effect symbol display area for displaying the right effect symbol are arranged in a substantially horizontal row. They are formed side by side (not shown). In each effect symbol display area, a symbol variation direction is set in a direction (vertical direction) substantially orthogonal to the arrangement direction of these display areas, and a plurality of effect symbols are sequentially displayed in that direction.

  The effect symbol display device 62 causes the effect symbols displayed in the display area of the display surface to change and stop display when the game ball enters the start opening 56B. Then, for example, when the production symbols are aligned with the same three-digit symbols “7, 7, 7” and stopped (determined display), the big winning opening 86 of the big winning device 84 arranged in the variable winning device 80 is opened. Is done. In the pachinko machine 10 of the present embodiment, when a game ball enters the start opening 56B, each effect symbol is changed, and the effect symbol is arranged in the same three-digit symbol, thereby giving a specific value of “big hit”. is there.

  Here, in the pachinko machine 10 of the present embodiment, for example, two types of big hits are set in advance. Specifically, there is a probable big hit that is established when three digits of the same odd-numbered effect symbols such as “7, 7, 7” are arranged. In addition, there is a normal jackpot that is established when the same even-numbered effects such as “8, 8, 8” are arranged in three digits.

  The probable big hit and the normal big hit are big hits having a relatively large number of rounds (for example, 15 rounds) and the opening time of the big winning opening 86 being about 26 seconds. For this reason, the number of prize balls is relatively large. In each big hit, a predetermined number (for example, 10) of game balls enter the big winning opening 86, or a predetermined time (for example, 10) even if a predetermined number (for example, 10) of the game balls do not enter. For example, when 26 seconds) elapses, the big winning opening 86 is closed and one round is completed.

  Further, the probability variation state is a state in which the probability of shifting to a big hit (meaning two kinds of big hits, a probable big hit and a normal big hit) becomes a predetermined high probability. The open time extended state is a state in which the opening time of the start port 56B is extended more than usual. For example, the normal opening time is about 0.1 seconds, while in the extended opening time state, it is extended to about 4 seconds. The start port 56B is opened by winning a normal symbol lottery, and functions as a normal electric accessory.

  In addition, after the probable big hit, the probability of shifting to the big hit becomes a special symbol probability fluctuation state in which the probability is higher than the normal gaming state. Then, the variation time of the special symbol and the normal symbol is shortened until the next big hit is generated, or until the special symbol variation display is performed a predetermined number of times (for example, 10,000 times), and the start port 56B. The open extension function is activated. In addition, after the normal jackpot, the probability of shifting to the big jackpot becomes a predetermined low probability state that is the same as the normal gaming state, and the variation time of the special symbol and the normal symbol is reduced by a predetermined number of times (for example, 100 times). When the opening extension function of the start port 56B is activated, the short game state is set.

  The center accessory 64 is mounted so as to protrude from the front peripheral portion of the effect symbol display device 62. The center accessory 64 has a pair of movable blade pieces 64A. The opening area of the warp entrance 58 is changed by the movement of the blade piece 64A.

  Further, as shown in FIG. 3, an identification symbol (which means an identification symbol of a special symbol and an identification symbol of a normal symbol) is displayed on the lower left side of the gaming area 28 based on a control signal from the main control board 102. A 7-segment display board (symbol display device) 68 to be controlled is arranged. The 7-segment display board 68 displays a 7-segment display 70 for displaying a special symbol identification symbol, four normal symbol hold display LEDs 72, four special symbol hold indication LEDs 74, and a normal symbol identification symbol. And two normal symbol display LEDs 76.

  Here, in the case of a probable big hit, a predetermined identification symbol (for example, a probable big hit symbol consisting of an odd number) is stopped and displayed on the 7-segment display 70. In the case of a normal big hit, another predetermined identification symbol (for example, a normal big hit symbol consisting of an even number) is stopped and displayed on the 7-segment display 70.

  Further, a normal symbol operation gate 78 is arranged on the left side of the effect symbol display device 62. A gate switch 124 (see FIG. 8) is disposed inside the normal symbol operating gate 78. As a result, when the game ball passes the normal symbol operation gate 78, the gate switch 124 is operated, and the normal symbol display LED 76 of the 7-segment display board 68 is variably displayed.

  Each normal symbol hold display LED 72 and each special symbol hold display LED 74 are composed of four round red LEDs, and are arranged close to the left and right sides of the 7-segment display 70. In this case, the number of game balls that have passed through the normal symbol operation gate 78 is set to hold the normal symbols up to four, and the lights are sequentially turned on and shifted for each passage. In addition, the number of game balls that have entered the start opening 56B is also reserved for up to four special symbols, which are sequentially lit and shifted for each incoming ball. Each time the variable display on the 7-segment display 70 starts, the number of unstarted times is exhausted, and one special symbol hold display LED 74 is turned off. Further, each time the normal symbol display LED 76 starts to change the normal symbol, the number of unstarted times is consumed, and one normal symbol hold display LED 72 is turned off. Then, when a predetermined jackpot symbol is stopped and displayed on the 7-segment display 70, a jackpot is generated and the jackpot 86 is opened. Further, when the two normal symbol display LEDs 76 are stopped and displayed in a predetermined display mode (a winning symbol), a normal symbol hit occurs and the start port 56B is opened. The special symbol identification symbol displayed on the 7-segment display 70 and the special symbol effect symbol displayed on the effect symbol display device 62 indicate the same game result (lottery result). .

  The start port 56B is disposed below the effect symbol display device 62 and is formed so as to open and close the pair of wing piece members 56A in a so-called tulip type. Inside thereof, a start port switch 120 (see FIG. 8) for detecting the passage of the game ball and a start port solenoid 130 (see FIG. 8) for operating the wing piece member 56A are provided. When the pair of wing piece members 56A are opened to the left and right, the opening area of the start port 56B is increased, and the possibility of entering a game ball is increased. When the pair of wing piece members 56A are closed and the separation distance is reduced. The opening area of the start opening 56B is reduced, and the normal state is reduced where the possibility of entering a game ball is reduced.

  The variable winning device 80 is disposed below the start opening 56 </ b> B, and includes a substrate 82 and a big winning device 84. Here, the grand prize winning device 84 is disposed substantially at the center, and has a grand prize winning opening 86 opened in a strip shape, an opening / closing plate 88 for opening or closing the special winning prize opening 86, and opening / closing the opening / closing plate 88. A large winning opening solenoid 132 (see FIG. 8) and a count switch 126 (see FIG. 8) for detecting a winning ball.

  A windmill 63 is disposed on the lower left side of the center accessory 64. Further, a pair of side lamps 90 are respectively disposed on the lower left portion and the lower right portion of the game area.

  Further, an out port 92 is provided below the game board 26, and a back ball preventing member 94 is provided below the out port 92. The back ball preventing member 94 prevents the game ball that has returned without reaching the game area 28 from returning to the launch position again. A foul ball prevention member 96 is attached to the tip of the inner rail 52.

  Next, an electronic control device that constitutes the pachinko machine 10 will be described.

  As shown in FIGS. 8 to 10, the electronic control unit includes a main control board 102, a payout control board 104, a sub control board 106, and a launch control board 108.

  The main control board 102 includes a CPU 102A and a ROM 102B. The CPU 102A of the main control board 102 controls the start opening solenoid 130, the big prize opening solenoid 132, the symbol display device 134, and the sub control board 106 based on the data stored in the ROM 102B. Further, the CPU 102A of the main control board 102 controls the entire game and mainly determines a game state such as determination of success / failure.

  In particular, the CPU 102A executes a jackpot lottery process (special game lottery process) triggered by the entry of a game ball into the start port 56B, and determines the success / failure using an arbitrary random number (special symbol determination random number). It has. The CPU 102A also has a function of determining a variation pattern (variation time) of the special symbol (identification symbol) with the execution of the special symbol determination.

  The variation pattern of the identification symbol corresponds to the effect pattern (game effect) of each effect symbol displayed on the effect symbol display device 62. The “determination of the variation pattern of the identification symbol” performed by the CPU 102A is “effect symbol”. Corresponds to “determining the production pattern (game production)”. When the variation pattern of the special symbol (identification symbol) (the production pattern of the production symbol) is determined, the 7-segment display 70 starts the variation display of the special symbol (identification symbol) and produces the production symbol display device 62. When the variation display of the effect symbol is started and the variation time specified by the determined variation pattern elapses, the special symbol and the effect symbol are stopped and displayed. The player's success / failure determination result (big hit lottery result) is notified to the player. The effect symbol display device 62 is arranged at a position approximately in the center of the surface (board surface) of the game board 26 so as to easily enter the player's field of view. On the other hand, the 7-segment display 70 is arranged at the end of the surface (board surface) of the game board 26 (the left end of the board surface in the present embodiment) so as not to easily enter the player's field of view. For this reason, it is common for a player to play a game while paying attention to the display content of the effect symbol display device 62.

  Then, the CPU 102A controls the payout of prize balls generated by the game balls entering into the sub-control board 106 that controls the change display and stop display of the above-described effect symbols, and various winning holes provided on the game board surface. The payout control board 104 for performing the control is directly controlled. Further, the CPU 102 </ b> A of the main control board 102 indirectly controls the effect display board 110, the amplifier board 112, the decoration drive board 114, and the effect button board 116 via the sub-control board 106.

  The ROM 102B of the main control board 102 stores a program for realizing control of the entire game executed by the CPU 102A.

  The main control board 102 is connected to the power supply board 109. When the operation of the pachinko machine 10 is started (power is turned on), a voltage is applied from the power supply board 109 to the main control board 102 and the control boards 104, 106, and 108. When the operation of the pachinko machine 10 is stopped (power is turned off), the application of voltage from the power supply board 109 to the main control board 102 and the control boards 104, 106, 108 is released.

  Further, the main control board 102 is electrically connected to the start port switch 120, the big prize port switch 122, the gate switch 124, and the count switch 126 via the relay terminal plate 118, respectively.

  In addition, the main control board 102 is electrically connected to the start port solenoid 130, the big prize port solenoid 132, and the symbol display device 134 via the relay terminal plate 128, respectively. The 7-segment display board 68 is an embodiment of the symbol display device 134.

  The payout control board 104 is electrically connected to the glass frame switch 138, the external tank switch 140, and the tank switch 142 via the relay terminal plate 136, respectively. Further, the payout control board 104 is electrically connected to the error LED 146 via the relay terminal board 144. The payout control board 104 is electrically connected to the lower pan full tank switch 148. Further, the payout control board 104 is electrically connected to a ball rental display board 152 and a ball rental apparatus (CR unit) 154 via a relay terminal board 150, respectively.

  The ball rental display board 152 is electrically connected with a ball rental switch 156 and a return switch 158, respectively. The payout control board 104 is electrically connected to a payout device 161 having a payout motor 162 and a payout switch 164 via a relay terminal plate 160. Further, the payout control board 104 is electrically connected to the main control board 102 and the launch control board 108, respectively.

  The payout motor 162 is driven by receiving a control signal related to paying out game balls from the main control board 102 and the payout control board 104. When the payout motor 162 is driven, the game balls that have moved through the payout passage 204 are supplied to the upper platen 18. Note that the number of game balls supplied to the upper plate 18 is specified by a control signal relating to the payout of game balls from the main control board 102 and the payout control board 104, and the specified number of game balls are discharged. Thus, the payout motor 162 is driven. The game balls supplied to the upper plate 18 move to the lower plate 20 and are finally launched into the game area 28 on the game board 26.

  The payout motor 162 can be driven when the power supply board 109 is in a power-on (power-on) state. However, even when the power supply board 109 is in a power-off (power-off) state, the main control is performed by a backup power supply unit (not shown). The substrate 102, the dispensing control substrate 104, and the dispensing motor 162 may be operable.

  The sub control board 106 is electrically connected to the effect display board 110, the amplifier board 112, the decoration drive board 114, and the effect button board 116, respectively.

  The sub-control board 106 controls game effects based on control signals from the main control board 102. The sub control board 106 includes a CPU 106A and a ROM 106B.

  The CPU 106 </ b> A of the sub control board 106 receives the control signal from the main control board 102 and controls each board such as the effect display board 110, the amplifier board 112, the decoration drive board 114, and the effect button board 116. The ROM 106B stores data necessary for controlling each board.

  As shown in FIG. 9, an effect display device 166 (62) and an effect display ROM 168 are electrically connected to the effect display board 110. In the effect display ROM 168, data (image data) of effect symbols that are displayed in a variable manner and stopped on the effect symbol display device 62 are stored. The effect symbol display device 62 is an embodiment of the effect display device 166.

  The amplifier board 112 is electrically connected to various speakers 170 (48) that output predetermined sound effects. The sub-speaker 48 is an embodiment of various speakers 170.

  In addition, various types of LEDs and lamps 172 (66) are electrically connected to the decorative driving board 114. The decoration driving board 114 receives a control signal from the sub-control board 106 and performs control related to game decoration. In addition, an operation switch 174 (40) is electrically connected to the effect button board 116. The lamps 66 are an embodiment of various LEDs / lamps 172. The effect button 40 is an embodiment of the operation switch 174.

  As shown in FIG. 10, a firing motor 180, a firing stop switch 182, an angle sensor 183, and a touch switch 184 are electrically connected to the firing control board 108 via a firing drive board 178. ing. The result of detecting the rotation angle (rotation amount) of the launch handle 24 by the angle sensor 183 is output to the launch control board 108 via the launch drive board 178, and the launch control board 108 is based on this detection result. The drive control of the firing motor 180 is executed via the firing drive board 178. As a result, it is possible to adjust the launch intensity of the game ball. In addition, when the firing stop switch 182 is turned on, a firing stop signal related to the game ball firing stop is output to the launch control board 108, and the launch control board 108 stops driving the launch motor 180 in response to the launch stop signal. To do. When the firing stop switch 182 is turned off, a firing signal for firing the game ball is output to the firing control board 108, and the firing control board 108 receives the launch signal and drives the launch motor 180. Thereby, the launching or stopping of the game ball is controlled. In this way, the game balls paid out to the upper plate portion 18 are sequentially launched into the game area 28 after passing through the lower plate portion 20. Further, a ball feed solenoid 186 is electrically connected to the launch control board 108.

  Next, the operation and effect of the pachinko machine 10 of the machine according to the first embodiment will be described.

  As shown in FIGS. 11 and 12, in a state where the pachinko machine 10 is installed in the island facility of the pachinko hall, the ball release valve 212 is positioned at the first rotation stop position. In a state where the ball removal valve 212 is positioned at the first rotation stop position, the inclined piece 218 of the ball removal valve 212 closes the inlet of the ball removal passage 206. Therefore, the game ball that has moved on the guide path 202 from the prize ball tank 200 falls freely from the guide path 202, but is not blocked by the inclined piece 218 of the ball release valve 212 and does not enter the inside of the ball release path 206. , Guided to the payout passage 204. That is, the game ball that has fallen freely from the guide path 202 collides with the inclined piece 218 and enters the payout path 204 as it is.

  The game ball that has entered the payout passage 204 moves through the payout passage 204 and eventually reaches the payout device 161. The payout motor 162 is driven based on a control signal related to payout of game balls from the main control board 102 and the payout control board 104, and the game balls are supplied to the upper dish portion 18. The game balls supplied to the upper plate 18 move to the lower plate 20 and are eventually launched into the game area 28.

  Here, in the state where the ball removal valve 212 is in the first rotation stop position, the engagement piece 220 of the ball removal valve 212 and the slide member 214 are engaged, and therefore the ball removal valve 212 has a center of gravity. Even when subjected to the action of gravity by the eccentric portion 222, it does not rotate about the rotation axis 216 from the first rotation stop position toward the second rotation stop position. In other words, in the state where the ball release valve 212 is in the first rotation stop position, the slide member 214 is always pushed upward by the elastic force of the spring member 226, so that the upper end surface of the slide member 214 is spherical. The lower end surface 221 of the positioning part 220C of the engagement piece 220 of the valve 212 is pressed upward. In this state, the slide member 214 is located at the upper stop position.

  At the same time, the inner surface of the slide member 214 comes into surface contact with the claw portion 220B of the engagement piece 220 of the ball release valve 212. That is, the ball removal valve 212 tries to rotate around the axis of the rotation shaft 216 from the first rotation stop position toward the second rotation stop position due to the influence of its own weight due to the gravity center eccentric portion 222. The claw portion 220B of the engagement piece 220 presses the inner surface of the slide member 214 in the lateral direction (right direction or horizontal direction when viewed from the back surface side). Rotation is prevented.

  As described above, the slide member 214 applies an upward pressing force to the lower end surface 221 of the positioning portion 220C of the engagement piece 220 of the ball release valve 212, and at the same time, the claw of the engagement piece 220 of the ball release valve 212. It will be in the state received to the pressing force of the horizontal direction from the part 220B. Thereby, the slide member 214 and the ball release valve 212 are in a relationship in which pressures in different directions are applied to each other, and a dynamic state is established in which one is positioned by the other. As a result, although the ball removal valve 212 is affected by its own weight due to the gravity center eccentric portion 222, the ball removal valve 212 is positioned and stopped at the first rotation stop position.

  Further, in a state where the ball release valve 212 is in the first rotation stop position, the inclined piece 218, the gravity center eccentric portion 222, and the engagement piece 220 are located inside the casing 203 and may protrude outside the casing 203. Therefore, parts (for example, connectors) on the island facility side of the pachinko machine do not come into contact with the inclined piece 218, the gravity center eccentric part 222, and the engagement piece 220. As a result, in the state where the ball removal valve 212 is in the first rotation stop position, the slant piece 218, the center of gravity eccentric part 222, and the engagement piece 220 due to contact of parts (for example, connectors) on the island facility side of the pachinko machine come into contact. Can prevent damage. Similarly, in a state where the ball removal valve 212 is in the first rotation stop position, the slide member 214 is located inside the casing 203 and does not protrude outside the casing 203. On the other hand, parts on the island facility side of the pachinko machine (for example, connectors) do not come into contact. As a result, in a state where the ball removal valve 212 is in the first rotation stop position, damage to the slide member 214 due to contact of parts (for example, connectors) on the island facility side can be prevented.

  On the other hand, when the pachinko machine 10 is taken out from the island facilities of the pachinko hall, or when maintenance work is performed, it may be necessary to discharge the game ball from the inside of the pachinko machine 10.

  In this case, as shown in FIG. 13, a hall-related person or an administrator presses the slide member 214 downward from the upper stop position. When the pressing force that presses the slide member 214 downward is larger than the elastic force of the spring member 226, the slide member 214 moves downward in a manner that opposes the elastic force of the spring member 226. .

  When the slide member 214 moves downward from the upper stop position, the engaged state between the slide member 214 and the ball release valve 212 is released. That is, since the upper end portion of the slide member 214 moves so as to slide on the claw portion 220B of the engagement piece 220, the inner surface of the slide member 214 and the claw portion 220B of the engagement piece 220 of the ball release valve 212 are connected. It becomes non-contact and both engagement is cancelled | released.

  When the engagement state between the slide member 214 and the ball release valve 212 is released, the ball release valve 212 is affected by its own weight due to the gravity center eccentric portion 222 functioning as a weight portion, and the first rotation stop position is 2 Turn around the axis of the rotary shaft 216 in the counterclockwise direction when viewed from the back side of the game board 26 toward the rotation stop position. Then, the ball removal valve 212 finally reaches the second rotation stop position.

  As shown in FIGS. 14 and 15, when the ball removal valve 212 has reached the second rotation stop position, the inclined piece 218 of the ball removal valve 212 opens the inlet of the ball removal passage 206. Thereby, the game ball that has moved on the guide path 202 from the prize ball tank 200 falls freely from the guide path 202 and enters the inside of the ball extraction path 206. In the state where the entrance of the ball removal passage 206 is open, the game ball that has fallen freely from the guide path 202 passes through the game ball distribution unit 208, but does not enter the payout passage 204, and remains vertical. It will enter the lower ball passage 206. The game ball that has entered the ball removal passage 206 is discharged to the outside of the pachinko machine 10 without going through the payout device 161. Thereby, all the game balls inside the pachinko machine 10 can be discharged to the outside without electrically operating the pachinko machine 10.

  Here, when the downward pressing force applied to the slide member 214 in the state where the ball release valve 212 has reached the second rotation stop position is released, the slide member 214 is pushed up by the elastic force of the spring member 226. It is done. As a result, the slide member 214 moves upward. As the slide member 214 moves upward, the upper end of the slide member 214 eventually engages with the groove portion 222 </ b> A of the gravity center eccentric portion 222 of the ball release valve 212. At this time, since a predetermined elastic force is always applied upward from the spring member 226 to the slide member 214, the upper end portion of the slide member 214 is always the groove portion 222A of the gravity center eccentric portion 222 of the ball release valve 212. Is pressed from the bottom to the top. As a result, the engagement state between the slide member 214 and the ball removal valve 212 is strong, and the positioning of the ball removal valve 212 at the second rotation stop position is promised.

  Furthermore, in the state where the ball removal valve 212 is in the second rotation stop position, the slide member 214 is located inside the casing 203 and does not protrude outside the casing 203. Parts on the island equipment side of the pachinko machine (for example, connectors) do not come into contact. As a result, in a state where the ball removal valve 212 is in the second rotation stop position, damage to the slide member 214 due to contact of parts (for example, connectors) on the island facility side can be prevented. Further, even when the slide member 214 moves up and down in the storage room 224, the slide member 214 is located inside the casing 203 and does not protrude outside the casing 203. On the other hand, parts on the island facility side of the pachinko machine (for example, connectors) do not come into contact. As a result, even when the slide member 214 moves up and down in the storage room 224, damage to the slide member 214 due to contact of parts (for example, connectors) on the island facility side can be prevented.

  Next, when the pachinko machine 10 is used, the ball removal valve 212 is rotated around the axis of the rotation shaft 216 from the second rotation stop position toward the first rotation stop position, and the first rotation stop is performed. It is necessary to stop at the position. In this case, since it is necessary to cancel the engagement state between the upper end of the slide member 214 and the groove 222A of the gravity center eccentric portion 222 of the ball release valve 212, the slide member 214 is pressed downward. As a result, the slide member 214 moves downward in a manner that opposes the elastic force of the spring member 226, and the engagement state between the upper end of the slide member 214 and the groove portion 222A of the gravity center eccentric portion 222 of the ball release valve 212. Is resolved. Then, the ball release valve 214 is pushed into the game ball sorting unit 208. As a result, the ball punch 212 rotates around the rotation axis 216 in the clockwise direction when viewed from the back side of the game board 26 from the second rotation stop position toward the first rotation stop position. Eventually, the ball release valve 212 reaches the first rotation stop position, and then releases the downward pressing operation on the slide member 214. As a result, the slide member 214 is pushed upward by the elastic force of the spring member 226, and as described above, the engagement state between the slide member 214 and the engagement piece 220 of the ball release valve 212 is established again.

  In particular, since the center of gravity eccentric portion 222 is provided with a curved piece 222B, when the ball release valve 212 is located at the second rotation stop position, the engagement piece 220 of the ball release valve 212 is connected to the game ball distribution portion. When pushed into the inside 208, the curved piece 222B presses the upper end surface of the slide member 214 downward and pushes the slide member 214 downward. Then, the ball release valve 212 rotates from the second rotation stop position side to the first rotation stop position side so that the curved piece 222B slides on the upper end surface of the slide member 214. As described above, when the ball release valve 212 is located at the second rotation stop position, the engagement piece 220 of the ball release valve 212 is moved to the inside of the game ball distribution unit 208 without pushing down the slide member 214 downward. It is possible to move the ball removal valve 212 to the first rotation stop position simply by pushing it into. In particular, by providing the curved piece 222B in the eccentric portion 222 of the center of gravity, the frictional force between the curved piece 222B and the upper end surface of the slide member 214 is reduced, so that the turning operation of the ball removal valve 212 can be facilitated.

  As described above, according to the pachinko machine 10 of the first embodiment, each rotation stop position of the ball release valve 212 can be easily switched by only a linear movement operation of the slide member 214. The ball extraction operation leading to the extraction passage 206 is easy and smooth, and the operation efficiency can be improved.

  In particular, since the switching operation between the payout passage 204 and the ball extraction passage 206 can be realized only by operating the slide member 214 up and down, a pin is not required unlike the conventional pachinko machine, and the switching operation of the ball extraction valve 212 is remarkably performed. Can be made easy. Further, since the ball valve 212 is not pulled out and protruded in the left-right direction (horizontal direction) of the pachinko machine 10, the slide member 214 can be operated even if there is no large space in the left-right direction of the pachinko machine 10.

  In addition, since the ball removal valve 212 is provided with the eccentric portion 222 of the center of gravity, the ball removal valve 212 is moved from the first rotation stop position by using the operation of the ball removal valve 212 as a weight portion of the eccentric portion 222 of the gravity center. 2 Automatically rotates around the rotation axis toward the rotation stop position. As described above, since the ball release valve 212 can be automatically (naturally) rotated about the rotation axis only by moving the slide member 214 linearly downward from the upper stop position, the first operation of the ball release valve 212 is performed. A rotation operation from the movement stop position toward the second rotation stop position can be easily performed.

  Further, in a state where the ball release valve 212 is located at the first rotation stop position, a predetermined pressure is applied between the slide member 214 and the positioning portion 220C (claw portion 220B) of the engagement piece 220 of the ball release valve 212. And is engaged firmly. In addition, in a state where the ball release valve 212 is located at the second rotation stop position, a predetermined pressure is applied between the slide member 214 and the groove 222A of the gravity center eccentric portion 222 of the ball release valve 212 to be firmly engaged. doing. As described above, in the state where the ball removal valve 212 is located at the first rotation stop position and the second rotation stop position, since the positions are firmly positioned, the posture and orientation of the pachinko machine 10 are determined. Even when the angle changes (or is unstable), the ball release valve 212 does not move from the respective rotation stop positions. As a result, it is possible to reliably execute the distribution work (payout work and ball removal work) of the game balls to the payout path 204 or the ball discharge path 206, and to stabilize the work efficiency at a high level. it can.

  In particular, the switching between the discharge passage 204 and the ball discharge passage 206 by the ball release valve 212 is realized only by manual movement of the slide member 214 in the linear direction. For example, the power supply board 109 of the pachinko machine 10 is turned off (power supply OFF). ), The payout passage 204 and the ball removal passage 206 can be switched. For this reason, when the power of the pachinko machine 10 is turned off and the pachinko machine 10 is removed from the island facility of the pachinko hall, the ball removing operation of the pachinko machine 10 can be executed, and the convenience can be improved. Further, since the switching between the discharge passage 204 and the ball removal passage 206 by the ball removal valve 212 is realized only by the manual movement of the slide member 214 in the linear direction, no electrical parts are required and the cost is suppressed. be able to.
