Description

  The present invention relates to a gaming machine that is installed and used in a game hall such as a pachinko parlor.

In general, a ball game machine such as a pachinko machine is equipped with a (special) variable prize winning device called a so-called attacker that opens when a big hit state is reached, and repeatedly releases for a relatively long time at the big hit. This makes it possible for a player to acquire a large amount of game balls.
Such a variable winning device includes a rectangular opening formed on the surface of the game board, which is a so-called large winning opening, and a door-shaped opening / closing member that opens and closes the opening. The opening is opened and closed by rotating around a horizontal rotation axis at the lower end of the opening.

The opening / closing member is arranged not only to open / close the opening but also to be inclined in a state where the upper surface is inclined downward to the opening on the front side of the lower end of the opening when the opening is opened. Yes. With such an opening / closing member, the game ball flowing down the position of the opening on the game board surface is restricted from passing in front of the opening formed along the game board surface, and the game ball flowing down by the opening / closing member The received game ball is guided to flow into the opening.
That is, simply having an opening along the surface of the game board causes the game ball to flow down along the surface of the game board, so that many game balls cannot flow into the opening in a short time. By guiding the game ball into the opening, a large number of game balls can flow into the opening in a short time.

  From the above, if you open the opening and closing member of the variable prize device called the attacker, you can win a lot of game balls in a short time and acquire a lot of game balls in a short time, so as an illegal act against gaming machines, There is a type in which a thin wire that can insert an opening / closing member into a gaming machine or a thin and thin plate of a transparent synthetic resin called a cell is used to forcibly open the opening / closing member with an external force.

  Therefore, in order to prevent such an illegal act, for example, when the movable rod of the solenoid is in a state of closing the opening / closing member between the opening / closing member and the solenoid that opens / closes the opening / closing member, the opening / closing member is opened / closed. There has been proposed one provided with a forcible opening protection mechanism for locking the opening of the member (see Patent Document 1).

Japanese Patent Application Laid-Open No. 2001-224771

  By the way, in the case of the configuration shown in Patent Document 1, fraudulent acts can be prevented by making it difficult to open the opening and closing member, but there are many movable members arranged between the movable lot of the solenoid and the opening and closing member. As a result, there is a problem that the rate of occurrence of a failure that causes the variable prize apparatus (electrical accessory) to not operate increases. Despite being in a big hit state, if the variable winning device does not open, the player will feel extremely uncomfortable, and the failure rate of the variable winning device will increase. There are business problems.

  In addition, by complicating the mechanism for opening the opening / closing member, there is a high possibility that fraud can be prevented. However, even if the mechanism for opening the opening / closing member is complicated, there is a change in appearance on the game board surface. There is no significant change in the shape and movement of the winning device, and the player cannot be impressed with the gaming machine, and no effect other than the prevention of fraud can be expected.

  The present invention has been made in view of the above circumstances, and it is possible not only to prevent fraudulent acts against a variable winning device that allows a player to acquire a large number of game balls by opening, but also varies depending on the player. It is an object of the present invention to provide a gaming machine that can impress a gaming machine with a novel shape and operation of a winning device.

According to the first aspect of the present invention, when a predetermined start condition based on a game ball that is launched into a game area provided on the game board surface and flows down the game area is satisfied, the game ball is not allowed to flow. The game area is provided with a variable winning device that converts the ball into a state in which it can flow in and easily flows in, and then returns to a state in which the game ball cannot flow again when a predetermined end condition based on the game ball is satisfied. In gaming machines,
The variable winning device includes an opening formed in the game board surface,
An opening / closing means that opens the opening when the start condition is satisfied and closes the opening when the end condition is satisfied;
It is formed independently with respect to the opening / closing means, and has a pair of left and right movable pieces. When the start condition is satisfied, one end of the pair of left and right movable pieces is connected to the lower edge of the opening. When the termination condition is satisfied, the pair of left and right movable pieces are moved from the inflow induction position to the inflow induction position that is connected to each other along the lower edge portion of the opening. And a guiding means for returning to a non-inflow guiding position,
The upper surfaces of the pair of movable pieces at the inflow induction position are inclined downward toward the lower edge of the opening.

According to the first aspect of the present invention, both the opening / closing means and the guiding means need to be operated in order for the game ball to flow (win) into the so-called large winning opening. That is, in the conventional attacker, the opening and closing member serves as both the opening and closing means for opening and closing the opening and the guiding means for guiding the game ball to the opening. However, in the present invention, the opening means and the guiding means are separate. It has become.
Accordingly, in order to allow a large number of game balls to flow into the opening by performing a fraudulent act, it is necessary to operate both the opening means and the guiding means simultaneously at the same time. Sufficient effort and time will be required for a person who commits cheating to hesitate to commit cheating until a large amount of inflow is possible. This can prevent fraud.

  In addition, the movable part of the variable prize device is increased to two types of opening / closing means and guiding means, but there is no need to provide a complicated mechanism such as a lock mechanism between the opening means or the movable part of the guiding means and the drive source. In each case, it is possible to divert the drive system in a conventional general electric accessory as it is, and the occurrence rate of failure does not increase in the variable winning device.

  Further, in the variable prize winning device, the opening / closing means opens the opening, and the pair of left and right movable pieces are separated from the lower edge of the opening and from the non-inflow induction positions separated from each other to the lower edge of the opening. Structure to prevent fraud that may seem like a player suspected of cheating due to the novel shape and movement of moving to inflow guiding positions that are linked together However, it is possible to impress a player with a gaming machine without making a bad impression on the player.

The invention according to claim 2 is the gaming machine according to claim 1,
The opening / closing means includes a door-shaped opening / closing member that opens / closes the opening, and the opening / closing member rotates around a horizontal rotation shaft provided on an upper end side of the opening to open / close the opening. It is characterized by doing.

According to the second aspect of the present invention, in the conventional attacker, the game ball is arranged on the lower side of the opening when opened by rotating around the horizontal rotation axis on the lower end side of the opening. The opening / closing member that has been guided to the opening rotates around the horizontal rotation axis at the upper end of the opening so that the opening / closing member is disposed on the upper side of the opening at the time of opening, preventing the game ball from flowing into the opening. It becomes a state to do.
Therefore, even if an unauthorized act such that the opening / closing member is forcibly moved so as to open the opening is performed, it is difficult for the game ball to flow into the opening, thereby preventing the unauthorized act.
In other words, after the opening is opened, the movable piece is arranged at the lower edge of the opening so that the game ball can be easily flowed into the opening for the first time. Can be prevented.

In addition, since the opening / closing member opens in the opposite direction to the conventional one, it becomes a variable winning device that performs a more innovative operation in combination with the operation of the movable piece described above, and can impress the player with the gaming machine.
In order to prevent the game balls from accumulating on the upper side of the opening / closing member, the game balls are guided by the game nail so that the game balls are not placed on the opening / closing member, or the game balls placed on the opening / closing member are opened and closed. It is preferable to incline the upper surface of the opening / closing member so that it flows down to the left or right of the member.

A third aspect of the present invention is the gaming machine according to the second aspect,
The left and right ends of the entire pair of movable pieces arranged at the inflow induction position and connected to each other are arranged at the inflow induction position so as to be arranged outside the left and right ends of the opening. The left and right length of the entire pair of movable pieces is longer than the left and right length of the opening,
When the pair of movable pieces are in the inflow induction position, a gap larger than the diameter of the game ball between the left and right ends of the opening / closing member and the other end portion outside the opening of each of the pair of movable pieces. It is characterized in that a rising piece is provided that opens substantially upwardly.

According to the third aspect of the present invention, the opening / closing member is disposed above the opening when the opening is opened, so that the movable piece is disposed on the lower side of the opening to guide the game ball to the opening. However, the inflow rate of the game balls to the opening is likely to decrease, but the width of the movable piece is widened so that the game balls flowing down both sides of the opening can be guided to the opening side. Further, by guiding the game ball with the rising piece, the winning rate of the game ball to the opening at the time of opening can be increased.
Further, the shape of the movable piece can be made more innovative.

The invention according to claim 4 is the gaming machine according to claim 3,
Each of the rising pieces of the pair of movable pieces arranged at the non-inflow induction position is in contact with the left and right ends of the opening / closing member so as to sandwich the opening / closing member from the left and right.

According to the invention of claim 4, when the movable piece is in the non-inflow induction position, that is, when the opening / closing member is in the closed position, the movable piece is sandwiched between the opening / closing member. The opening / closing member is difficult to open, and an illegal act of forcibly opening the opening / closing member can be prevented more reliably.
Even in this state, even if the opening / closing member may be opened due to fraud, the opening / closing member that is forcibly opened above the opening at the non-inflow induction position is adjacent to the left and right of the opening / closing member. The movable piece is placed, the opening is surrounded by the opening and closing member and the left and right rising pieces, the game ball is not allowed to approach the opening, and the game ball flows into the illegally opened opening. It can be surely prevented.

The invention according to claim 5 is the gaming machine according to claim 3 or 4,
Guiding pieces for guiding a game ball between the opening and closing member and the rising piece are formed on the left and right ends of the opening and closing member.

  According to the fifth aspect of the present invention, the guide ball prevents the game ball from climbing on the open / close member from the left and right sides of the open / close member, and the game ball in contact with the guide piece is removed from between the guide piece and the rising piece. Even if the opening / closing member can be guided to the opening side and the opening / closing member is disposed on the opening when the opening is opened, it is possible to prevent the inflow rate of the game balls to the opening from decreasing.

  According to the gaming machine of the present invention, although it is a variable winning device for preventing fraud that may seem to be suspected as if the player is cheating, it has never been Since it has a novel structure and performs an unprecedented new operation, it is possible to impress a player with a gaming machine without giving a bad impression to the player.

  Hereinafter, with reference to the drawings, a gaming machine (for example, a ball) that is installed in a place such as a game machine-installed store and that allows a player to play a game based on supply of gaming media (for example, a gaming ball or medal). The configuration and operation of a pachinko gaming machine as a gaming machine will be described.

  The pachinko gaming machine has a basic configuration as a so-called “digipachi” type of pachinko gaming machine except for the special variable prize device described later, and is attached to the island facility in the form of a rectangular frame like a known pachinko gaming machine. Machine frame (not shown), a front frame (not shown) that is attached to the machine frame so as to be openable and closable, and that has a housing for accommodating the game board 1, and a door that opens and closes in front of the front frame.

In the game area 2a on the board surface of the game board 1, a variable display device 3 is provided slightly above the center. The variable display device 3 is composed of, for example, a liquid crystal display device and displays a lottery result that is out of the lottery performed by the main control device functioning as a lottery means. Is displayed, and the lottery result described above is displayed by winning or losing the variation display game.
That is, the variable display device 3 displays a variable display game with decorative symbols.

  A variation display game is basically a well-known game, for example, a plurality of decorative symbols (identification information) such as numbers are displayed in a variable manner so as to be switched in a plurality of display areas, and a variation in a variation pattern determined in advance by lottery. When the display time elapses, the variable display is terminated, and one decorative symbol is stopped and displayed in each display area, and the combination of the stopped decorative symbols is a special combination (for example, display The special game state is generated as a win when the symbols to be played are all the same symbol). The variable display device 3 is not limited to the liquid crystal display device, and various known display devices can be used.

  Further, in the variable display device 3, not only the decorative symbols are sequentially switched and displayed in the above-mentioned display of the variable display game, but also various stunning displays are performed, and characters and other characters related to the decorative symbols are displayed. Animation display is also performed.

  The variable display device 3 is surrounded by a peripheral wall 16 that prevents the inflow of game balls. In addition, a stage 17 is formed at the bottom portion of the peripheral wall 16 so that game balls can jump from the lower side and flow in, and a part of the flowed game balls is guided to the normal variation winning device 5 described later. Yes. In addition, the peripheral wall 16 includes, for example, an inflow port for game balls provided on the outside of the side portion, an outflow port for flowing out the game balls toward the stage 17, and a flow path connected to the outflow port from the inflow port. A part of the game ball flowing down around the peripheral wall 16 is guided to the stage 17.

An ordinary variable winning device 5 is provided directly below the variable display device 3. The normal variation winning device 5 has a so-called electric tool as an electric accessory, and serves as a special symbol starting prize opening (special figure starting prize opening) between the two left and right movable members 41, 41 constituting the electric accessory. A start winning opening is provided. In a normal state, the movable pieces 41 and 41 are closed with an interval that allows only one game ball to flow down, and the result of a normal symbol variation display game (a general symbol variation display game) described later is a hit. In such a case, the two movable pieces 41 are opened for a preset time.
That is, the normal variation winning device 5 is configured to vary between a closed closed state in which the game ball is difficult to win and an open / closed state in which the game ball is more likely to win in comparison with the closed state.
In addition, the start winning opening is a lottery start opportunity (variable display game) based on the winning of a game ball to a main control device functioning as a lottery means for performing a lottery for determining the winning of the variable display game as will be described later. Start opportunity).

  That is, a start winning ball detection sensor for detecting a game ball won in the normal variation winning device 5 is provided corresponding to the normal variation winning device 5, and the start winning ball detection sensor detects a game ball, that is, Based on the fact that the game ball has won the normal variation winning device 5, an opportunity to start the above-described variation display game with decorative symbols is given.

  A special figure reservation number display lamp 7 is provided at the upper left of the variable display device 3. When the starting winning ball detection sensor detects a game ball that has won the normal variation winning device 5, 1 is added to the special figure starting memory number within the range of the upper limit, and the variable display game starts based on this starting winning. When it is done, 1 is subtracted from the special figure starting memory number. The number of special figure starting memories, that is, the number of triggers (starting rights) for starting the variable display game is displayed on the special figure holding number display lamp 7.

Further, in the game area 2 a on the game board 1, a special variable winning device 8 according to the present invention is provided below the variable display device 3 and further below the normal variable winning device 5. The details of the special variable winning device 8 will be described later.

When the open / close solenoid 27 is turned off and the rod 32 moves to the retracted position, the open / close transmission shaft 30 moves downward along a circular arc centered on the shaft portion 35 in a direction perpendicular to the length direction thereof. Move to. When the power of the open / close solenoid 27 is turned on again, the open / close transmission shaft 30 moves along the arc in a direction opposite to the above-described direction, and returns to the position where the above-described open / close solenoid 27 is off.

That is, the open / close transmission shaft 30 moves up and down in response to the forward / backward movement of the open / close solenoid 27. When the opening / closing transmission shaft 30 moves up and down along the arc, the opening / closing member 21 having the transmission engaging portion 29 with which the tip of the opening / closing transmission shaft 30 engages opens and closes.
As described above, the opening / closing means 22 includes the door-shaped opening / closing member 21 that opens and closes the opening, and the opening / closing member 21 is different from the conventional attacker in that the horizontal rotation shaft provided on the upper end side of the opening. Rotate around 23 and 23 to open and close the opening.

  Therefore, in a state where the opening / closing member 21 is closed, it goes without saying that it is impossible to win a game ball in the opening. However, even when the opening / closing member 21 is in the opened state, the opening / closing member 21 remains on the opening. When the game ball flowing down the board surface of the game board 1 tries to pass through the opened opening, it hits the opening / closing member 21 disposed on the opening, and cannot flow down to the opening. Therefore, it is clear that the opening / closing member 21 does not guide the game ball to the opening serving as a big winning opening unlike the opening / closing member of the conventional attacker.

Therefore, since the opening / closing means 22 cannot guide the game ball to the opening, the opening / closing means 22 for opening / closing the opening serving as the big prize opening is independent of the guiding means 42 for guiding the game ball to the opening. Will do.
And the guide means 42 formed independently with respect to the opening / closing means 22 is a guide member that guides the game ball to the opening serving as a big prize opening as shown in FIGS. 2, 4, 5, and 6. A pair of left and right movable pieces 41, 41, an induction solenoid 43 as a drive source for driving the movable pieces 41, 41, and an induction transmission member 44 for transmitting the driving force of the induction solenoid 43 to the pair of movable pieces. And have.

  The movable pieces 41, 41 are arranged along the lower edge of the opening so as to guide the game ball to the opening serving as a big winning opening when the inflow guiding position is reached, and the inflow guiding position And an inflow guide portion 45 for connecting one end to each other and the other end portion side of the inflow guide portion 45, and flows down in the vicinity of either the left or right end portion of the openable opening / closing member 21 at the inflow guide position. A rising piece 46 that guides the game ball to be guided onto the inflow guide portion 45, a rotation shaft 47 that is perpendicular to the board surface, and an engagement shaft 48 that engages with the induction transmission member 44.

  The inflow guide portion 45 has a substantially rectangular parallelepiped shape that is long to the left and right, and is arranged along the lower edge portion of a rectangular opening (big prize opening) that is long to the left and right at the inflow guide position. Further, the inflow guide portion 45 is a part of each of the pair of left and right movable pieces 41 and 41 and is arranged in a pair of left and right. At the inflow guiding position, the pair of inflow guide portions 45, 45 are arranged in a straight line, and the left and right inflow guide portions 45, 45 are at the center of the opening at the center of the opening. It is in the state which contact | abutted one edge part which becomes.

In addition, the left and right lengths of the inflow guide portions 45 are longer than ½ of the left and right lengths of the openings, and as described above, one end portion on the center side of the openings of the inflow guide portions 45 and 45. When the pair of inflow guide portions 45, 45 are arranged in a straight line, the other end of the pair of guide portions 45, 45 is outside the left and right ends of the opening (left side, On the right side).
That is, the left and right ends of the entire pair of movable pieces 41, 41 arranged at the inflow induction position and connected to each other are arranged at the inflow induction position so as to be arranged outside the left and right ends of the opening. The left and right lengths of the pair of movable pieces 41 and 41 are made longer than the left and right lengths of the opening.

  Further, the upper surfaces of the inflow guide portions 45, 45 are inclined downward from the front to the rear at the inflow guide position. In addition, the lowest portion of the inflow guide portions 45, 45 on the downside inclined surface side on the board surface side is slightly higher than the lower edge portion of the opening. That is, the upper surfaces of the pair of movable pieces 41, 41 (inflow guide portions 45, 45) at the inflow induction position are inclined downward toward the lower edge of the opening.

  The inflow guide portions 45, 45 are rotatable in a direction of lowering one end portion around the rotation shafts 47, 47 provided on the other end portion side. The pivot shafts 47 and 74 may be movable to the left and right with respect to the special variable winning device unit. That is, in the pair of inflow guide portions 45 and 45 in a state where the one end portions are in contact with each other, when the inflow guide portions 45 and 45 are rotated, the one end does not interfere with each other and cannot be rotated. It is only necessary that the part can be moved downward in an arc shape. For example, the position of the rotation shafts 47, 47 is formed on the upper edge portion of the inflow guide portions 45, 45, or the rotation shafts 47, 47 are movable left and right as described above. It is only necessary that the pair of inflow guide portions 45, 45 in which the end portions are in contact with each other are rotatable in a direction in which one end portion is lowered.

  Further, the inflow guide portions 45, 45 rotate so that one end portion of the inflow guide portions 45, 45 on the central side of the opening portion is lowered from the inflow guidance position at the non-inflow guidance position as described above. As a result, the inflow guide portions 45, 45 are separated downward from the opening, and the game ball cannot be directly guided to the opening. In addition, at the non-inflow guidance position, a pair of inflow guide portions 45, 45 are arranged in an inverted C shape.

The rising pieces 46, 46 are substantially triangular members that extend obliquely upward from the other end of the inflow guide portions 45, 45, and are formed as a pair corresponding to the pair of movable pieces 41, 41. ing. The pair of rising pieces 46, 46 are arranged so as to open to the left and right, and the side surfaces substantially facing each other are inclined surfaces that are inclined downward toward the center of the opening.
As a result, the rising pieces 46 and 46 guide the game ball flowing down to the right or left slightly onto the inflow guide portions 45 and 45 from the opening serving as the big winning opening.

  When the inflow guide portions 45 and 45 are horizontally disposed along the lower edge of the opening at the inflow guiding position, the inflow guide portions 45 and 45 are disposed on the slopes on the opening side of the rising pieces 46 and 46 and the positions of the openings. The space between the outer side surfaces of the guide pieces 26 and 26 that are the left and right ends of the open / close member 21 in the open state is longer than the diameter of the game ball.

  As a result, when the special variation winning device 8 is in the open state, that is, when the opening / closing member 21 of the opening / closing means 22 is in the open state and the movable piece 41 of the guiding means 42 is in the inflow induction position, The game balls are caused to flow onto the inflow guide portions 45, 45 of the movable piece 41 from between the guide pieces 26, 26 and the rising pieces 46 of the movable pieces 41, 41 located on the left and right sides of the guide pieces 26, 26. In addition, the game ball that has flowed onto the inflow guide portions 45, 45 wins (inflows) into the opening portion that becomes a big winning opening along the inclination of the upper surface of the inflow guide portions 45, 45.

  That is, when the pair of movable pieces 41, 41 are in the inflow induction position, the game ball between the left and right ends of the opening / closing member 21 at the other end portion outside the opening of each of the pair of movable pieces 41, 41. Rising pieces 46, 46 are provided that are substantially upwardly spaced apart from each other by a distance larger than the diameter.

The rising pieces 46, 46 rotate around the rotation shafts 47, 47 when the movable pieces 41, 41 are in the non-inflow position, and the slopes of the rising pieces 46, 46 on the above-described opening side. Are in contact with the left and right end surfaces of the opening / closing member 21, that is, the side surfaces that are the outer sides of the guide pieces 26, 26.
That is, each of the rising pieces 46 and 46 of the pair of movable pieces 41 and 41 arranged at the non-inflow induction position is in contact with the left and right end portions of the opening and closing member 21 so as to sandwich the opening and closing member 21 from the left and right. become.

  Engagement shafts 48, 48 of the pair of movable pieces 41, 41 are arranged in parallel to the rotation shafts 47, 47 on the opening side that is inside the rotation shafts 47, 47. That is, the engagement shafts 48 and 48 are arranged at positions eccentric with respect to the rotation shafts 47 and 47.

  Since the engagement shafts 48 are on the one end side of the rotating shafts 47 and 47 in the inflow guide portions 45 and 45 of the movable pieces 41 and 41, the movable pieces 41 and 41 are connected to the inflow guide portions. One end and the other end of the inflow guide portions 45, 45 are moved upward from the non-inflow induction position where one end on the opening side of the 45, 45 is lowered. It becomes the inflow induction position where the part is at substantially the same height. On the contrary, the movable pieces 41 and 41 are brought into the non-inflow induction position by lowering the engagement shafts 48 and 48 from the inflow induction position.

The movable pieces 41 and 41 are moved between the non-inflow induction position and the inflow induction position by the induction solenoid 43 and the induction transmission member 44.
The induction solenoid 43 is a well-known electromagnetic actuator that moves the rod 49 forward and backward. For example, the rod 49 is biased in the forward direction by a spring (biasing means) such as a coil spring when the power is turned on. When the power is turned off in this state, the retracted rod 49 moves forward by the urging force of the urging means.

The movable pieces 41 and 41 are in the non-induction position when the power-off rod 49 is advanced, and the movable pieces 41 and 41 are in the induction position when the rod 49 is retracted when the power is on.
In addition, a disc-shaped engagement portion 50 that engages with the induction transmission member 44 is provided at the distal end portion of the rod 49. The engaging part 50 has a rod 49 connected to the center thereof. That is, the engaging part 50 and the rod 49 are arranged coaxially.

As described above, the movable pieces 41, 41 that are rotatable about the rotation shafts 47, 47 and the induction solenoid 43 are connected by the induction transmission member 44.
The induction transmission member 44 includes a rotation locking portion 51 that engages with the engagement portion 50 at the tip of the rod 49 of the induction solenoid 43, rotary shafts 52 and 52 that rotatably support the rotation locking portion 51, and rotation. Left and right induction transmission engaging portions 53, 53 extending in a direction orthogonal to the rotation shafts 52, 52 from the locking portion 51 are provided.

The rotation shafts 52 and 52 are fixed to a special variable prize device unit described later, and the rotation locking portion 51 rotates around the rotation shaft.
Further, the rotation locking portion 51 extends horizontally along the board surface of the game board 1, and induction transmission engagement portions 53 are provided at both ends thereof. And the rotation latching | locking part 51 is from the 1st engaging part 54 of the round bar shape extended from right and left, and the 2nd engaging part 55 which is the same round bar shape, and is arrange | positioned in parallel with the 1st engaging part 54. However, the 2nd engaging part 55 is cut in the middle, and is in the state divided into right and left. Further, the first engagement portion 54 and the second engagement portion 55 are disposed so as to be perpendicular to the rod 49 of the induction solenoid 43.

Then, the upper portion of the engaging portion 50 at the tip of the rod 49 is inserted between the first engaging portion 54 and the second engaging portion 55 from the lower side, and the rod 49 is locked to the rotation locking portion 51. It is in the state.
Further, the first engagement portion 54 and the second engagement portion 55 are arranged in a state of being eccentric to the upper side of the rotation shafts 52, 52.

  Then, when the rod 49 of the induction solenoid 43 moves back and forth, the rotation locking portion 51 engaged with the engagement portion 50 rotates about the rotation shafts 52 and 52. As a result, the induction transmission engaging portions 53 and 53 provided at the left and right end portions of the rotation locking portion 51 are also rotated, and arm portions 58 and 58 (described later) provided at the tip end portions thereof are moved up and down along the arc. It has become. The rotary shafts 52 and 52 and the rod 49 are arranged so as to be at right angles to each other. In addition, the rod 49 and a coil spring as an urging means disposed around the rod 49 and the periphery thereof are disposed at a portion of the second engagement portion 55 that is cut and spaced apart.

  C-shaped arm portions 58 and 58 are provided at the distal ends of the induction transmission engaging portions 53 and 53, respectively. The engagement shafts of the movable pieces 41 and 41 are provided on the C-shaped arm portions 58 and 58, respectively. 48 is held in a lightly picked state. Accordingly, the left and right movable pieces 41 and 41 can be moved between the non-inflow induction position and the inflow induction position by moving the induction transmission engaging portions 53 and 53 up and down.

  That is, when the induction solenoid 43 is powered off and the rod 49 is in the forward position, the arm portions 58 and 58 of the induction transmission engagement portions 53 and 53 and the engagement shaft 48 engaged with the arms 58 and 58 are at the lowest. The movable pieces 41, 41 are in a non-inflow induction position in which the inflow guide portion 45 has an inverted C shape and the open / close member 21 is sandwiched from the left and right by the left and right rising pieces 46, 46;

  When the induction solenoid 43 is powered on and its rod 49 is in the retracted position, the arm portions 58 and 58 of the induction transmission engagement portions 53 and 53 and the engagement shaft 48 engaged therewith are at the top. In this case, the pair of movable pieces 41, 41 has a straight inflow guide portion 45 and can receive a game ball between the guide pieces 26, 26 of the opening / closing member 21 with the left and right rising pieces 46, 46. It becomes the inflow induction position.

  In this example, the opening / closing means 22 and the guiding means 42 are configured as one special variable winning device unit, and an opening is formed in a portion of the game board 1 where the special variable winning device 8 is formed. The special variable winning device 8 is attached to the game board 1 by fitting and installing the variable winning device unit. Therefore, the special variable winning device unit has a plate portion that closes the opening formed in the game board 1 and becomes a part of the surface of the game board, and this portion serves as a large winning opening of the special variable winning device 8. An opening is formed, and members that need to be fixed to the opening / closing means 22 and the guiding means 42 are fixed.

And the special variation prize-winning apparatus 8 is comprised from the above-mentioned opening-and-closing means 22, the guidance means 42, and an opening part.
Then, when the above-described start condition is satisfied for the special variable winning device 8, the opening / closing means 22 changes the opening / closing member 21 from the closed state to the open state, and the guiding means 42 guides the pair of movable pieces 41, 41 to non-inflow. From the position to the inflow induction position.

  As a result, the opening is opened. However, since the opening / closing member 21 has a bowl shape on the opening as described above, the game ball about to flow down from the opening to the front of the opening is opened and closed. It will be blocked by the member 21. In this example, in order to prevent the game balls from accumulating on the opening / closing member 21, the game balls flowing down on the opening / closing member 21 are guided to the left and right sides of the opening / closing member 21 by game nails (not shown). The game ball is prevented from flowing down just above the opening / closing member 21.

  A part of the game ball above the opening and closing member 21 and flowing down the left and right sides of the opening and closing member 21 includes guide pieces 26 and 26 at the left and right end portions of the opening and closing member 21 and a movable piece 41 which is the left and right sides thereof. , 41 between the rising pieces 46, 46. The game ball that has flowed in between the rising pieces 46 and 46 and the guide pieces 26 and 26 reaches the inflow guide portions 45 and 45 of the movable pieces 41 and 41. The inflow guide portions 45, 45 of each of the pair of movable pieces 41, 41 are arranged in a straight line horizontally along the lower edge portion of the opening portion, abut against each other, and the upper surface thereof is the lower edge of the opening portion. Since it is inclined downward toward the part, all the game balls reaching the inflow guide parts 45, 45 are guided into the opening part, and these game balls win the opening part.

The average number of game balls per unit time flowing between the rising pieces 46, 46 and the guide pieces 26, 26 can be adjusted by a flow regulation changing member such as a game nail or a windmill. A similar inflow rate of game balls per unit time can be easily realized.
Next, when the termination condition is satisfied, the opening / closing means 22 changes the opening / closing member 21 from the open state to the closed state, and the guiding means 42 changes the pair of movable pieces 41, 41 from the inflow induction position to the non-inflow induction position.

  In this state, for example, the special variable winning device 8 is in a state where the special gaming state has not occurred in the special variable winning device 8 due to an illegal act using a cell, a wire, or the like, that is, the start condition is not satisfied. If the opening / closing member 21 is to be opened, the open / close member 21 needs to be opened and the movable pieces 41, 41 need to be in the inflow induction position.

Here, when the opening / closing member 21 is opened and the movable pieces 41, 41 are in the non-inflow induction position, it becomes difficult for the opening / closing member 21 to win a game ball from above the opening as described above. Since the movable pieces 41, 41 that are in the non-inflow position are arranged in the lower part from the left and right side parts of the opening part, it is difficult to win a game ball from the side of the opening part.
In particular, the movable pieces 41, 41 in the non-inflow position are in contact with the guide pieces 26, 26 whose rising pieces 46, 46 are the left and right ends of the opening / closing member, and inflow guide portions integral with the rising pieces 46, 46. 45 and 45 will be in the state which enclosed the lower left and right of the opening part.

  Thereby, the opening is covered with the opening / closing member 21 on the upper side, the left and right sides are covered with the rising pieces 46, 46 of the movable pieces 41, 41, and the inflow guide part of the movable pieces 41, 41 on the lower left and right sides thereof. There is a portion that is covered by 45 and 45 and is open only at the portion directly below the periphery of the opening, and the rest is surrounded by the front. Therefore, it is almost impossible for a game ball to flow in even when the opening is open. That is, even if it is away from the opening, it is completely prevented that the game ball hits the movable pieces 41, 41 on the lower side and jumps up and wins the opening.

  Further, the rising pieces 46, 46 of the movable pieces 41, 41 at the non-inflow induction position sandwich the opening / closing member 21 from the left and right, and the end face of the opening / closing member 21 is the end face of the plate body by the guide pieces 26, 26. Unlike, it has a large area. Since the guide pieces 26 and 26 and the rising pieces 46 and 46 can be brought into surface contact with a relatively large area, the opening / closing member 21 is provided even though the movable pieces 41 and 41 are not moved from the non-inflow induction position to the inflow induction position. If the opening / closing member 21 is illegally opened, the movement of the opening / closing member 21 is hindered by the frictional resistance of the contact portion between the guide pieces 26, 26 and the rising pieces 46, 46. In addition, the opening / closing member 21 is slightly difficult to open.

On the other hand, even if only the movable pieces 41, 41 are illegally converted from the non-inflow induction position to the inflow induction position, the opening is closed by the opening / closing member 21, so that the game ball cannot win the opening.
From the above, in the special variation winning device 8 of the present invention, in order to allow a large amount of game balls to flow in other than the special game state, the open / close member 21 is illegally opened and the movable pieces 41 and 41 are simultaneously opened. Must be in the inflow induction position, making fraud extremely difficult.

Further, the opening / closing means 22 and the guiding means 42 have drive sources (opening / closing solenoid 27, induction solenoid 43) independently of each other and do not have a mechanism for interlocking with each other. By setting the open state, the movable pieces 41 and 41 of the guiding means 42 do not interlock and become the inflow induction position, and conversely, by setting the movable pieces 41 and 41 of the guiding means 42 to the inflow induction position, The open / close member of the open / close means 22 is not interlocked to be opened.
In addition, by improperly operating the part that becomes the interlocking mechanism, the opening and closing member 21 can be simultaneously opened by one operation, and the movable pieces 41 and 41 cannot be set to the inflow induction position.

Therefore, if the opening / closing means 22 and the guiding means 42 cannot be illegally operated at the same time, it is not possible to perform an illegal act of acquiring a large amount of game balls with the special variable winning device 8 being in an open state although it is not in a special gaming state. In addition, since it is difficult to illegally operate the two members at the same time, the gaming machine of this example can reliably prevent the illegal act.
Further, the special variation winning apparatus 8 of this example is such that the opening / closing member 21 opens upward with respect to the conventional attacker, and even if the opening / closing member 21 is opened, the inflow of game balls to the opening is obstructed, and Since the left and right movable pieces 41 and 41 rotate so as to be in contact with and away from each other below the winning opening, an extremely novel variable winning device is obtained.

  As described above, this variable winning device prevents fraudulent acts. However, the player will be regarded as a variable winning device that makes a novel movement that has never been seen before. That is, the special variation winning device 8 in this example is not considered to be a structure for preventing illegal acts by the player, and is likely to be regarded as an interesting special variable winning device 8. As a result, the design and game characteristics of the machine are improved.

  As mentioned above, although the embodiment to which the invention made by the present inventor is applied has been described, the present invention is not limited by the description and the drawings that form part of the disclosure of the present invention according to this embodiment. That is, it should be added that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on this embodiment are all included in the scope of the present invention.
