Abstract

PROBLEM TO BE SOLVED: To feed game balls that are sequentially fed in towards a flow passage while retaining a coarse/dense balance of the game balls within a prescribed tolerance with respect to a feed-in period at a game board uppermost part including the flow passage formed between a circular-arc rail provided around a peripheral edge of the game board and a generator provided at the center of the game board.SOLUTION: The game machine includes a step part 202 that can clearly distribute, at a top plate part 200 of a center generator 105, even a game ball PB that passes through a rail 102 and "a prescribed pin 19S" and is to be "shot rightward", to the left and the right according to a predetermined deceleration rate. This configuration can avoid such an occurrence that a strong game ball PB is shot subsequently to a stagnant game ball, the strength of which is weakened, and that the game balls PB are connected in a line and flow the right side of the center generator 105.

Description

  The present invention receives a game ball that falls off the arc surface of the rail portion due to a decrease in the flow velocity of the game ball, and has a game board in which the game progresses according to the fall state due to the weight of the game ball Related to the machine.

  Conventionally, in game machines, particularly pachinko machines, a special symbol lottery (winning lottery) is made by fetching a random number for winning lottery at the timing of detecting a pachinko ball that won a winning prize opening (special symbol starting prize winning port), As a result of this special symbol lottery, the winning prize opening is opened a predetermined number of times for a predetermined period (one opening and closing is one round, and generally continues for 10 to 16 rounds in total). There is a pachinko machine that has a function (a big role processing) that makes it advantageous for the player to enhance.

  The grand prize winning hole in this big game process has a maximum number of winning balls of one round (for example, 8 to 10 balls), and even when the predetermined period has not elapsed, the maximum winning ball number is reached. The end of the round (closed).

  The game balls are fired at a fixed period by the launching device (for example, at intervals of 6 seconds), but the game balls on the game board collide with obstacles such as nails and windmills on the game board surface, or subsequent balls, etc. Due to the collision with the ball, the balls approaching the game board large winning opening are not concentrated at regular intervals, and the maximum number of winning balls may be exceeded depending on the winning detection timing. For example, for every +1 ball, there will be 10 to 15 prize balls.

  Here, there is a pachinko machine with a game specification in which a big winning opening is arranged in the vicinity of the lower right of the game board and the firing strength is changed from normal left-handed to right-handed at the time of the big game.

  In this case, if the player changes the firing strength in order to make a right strike during the big game, the game ball moves along the inner peripheral surface of the arc-shaped rail with a so-called centrifugal force and is placed at the center of the game board. Go over the center role that was placed, then flow down from the right side of the center role of the game board to the big prize opening.

  Patent Document 1 proposes a handle grip device that facilitates fine adjustment of the distance at which a player can launch a ball by operating a handle lever.

  Patent Document 2 proposes a ball firing control handle that can set normal or right-handed strength by switching a switch, separately from adjustment of firing strength by the handle.

  In any case, the player advances the game during the big game process with a higher firing strength than during the normal game.

  Here, if the maximum launch intensity is maintained by operating the steering wheel during the big game process, the game balls moving along the inner peripheral surface of the rail reach the big prize opening at almost regular intervals, and are almost at the maximum winning prize. The round can be digested without exceeding the sphere.

JP 2004-24664 A Japanese Patent Laid-Open No. 9-276484

  However, by adjusting the firing timing of each pachinko ball and adjusting the firing position by steering operation (ie, firing strength adjustment), the momentum drops at the top of the game board and disengages from the inner peripheral surface of the rail. There is a point where the game ball flows in the clockwise direction while decelerating by rolling on the ceiling surface of the center accessory.

  If the pachinko ball is fired at the normal right-handed firing intensity following this decelerated pachinko ball, the game ball will be in a so-called beaded state, reaching the big prize opening as it is and winning beyond the maximum number of winning balls. May increase the probability of

  In consideration of the above-mentioned fact, the present invention provides the flow path at the top of the game board where a flow path is formed between an arc-shaped rail provided at the periphery of the game board and an accessory provided at the center of the game board. An object of the present invention is to obtain a gaming machine that can send out game balls that are sent one after another while maintaining a coarse / dense balance between the game balls within a certain allowable range with respect to the period when the balls are sent.

  According to the first aspect of the present invention, the rail that guides the game ball that is launched with the launch intensity based on the operation amount of the operation unit along the concave arcuate surface, and the flow velocity of the game ball A game board which receives the game ball falling off the arc surface of the rail portion due to attenuation and falls, and the game progresses according to the fall state due to the weight of the game ball, and the game board is provided with a convex shape A top plate portion formed with an arcuate surface, and a reference for determining a launch strength of a game ball provided at an upper end portion of the game board and reaching a flow path formed between the top plate portion and the rail portion; And a game ball that is provided on the top plate portion and that passes through the passage gate portion, reaches the flow path, and is supported by the top plate portion, with a specific position of the top plate portion as a boundary. Sorting to guide in the target direction or other directions It has a stage, a.

  According to the present invention, a game ball launched at a launch intensity based on the operation amount of the operation unit is guided by flowing along the concave arc surface of the rail unit.

  The guided game ball will eventually decay in flow velocity, fall off the arc surface of the rail and fall, and the game board receives this, and on the game board, the game ball responds to the fall state due to its own weight. Progresses.

  A passing gate portion is provided at the upper end portion of the game board, which serves as a reference for determining the firing strength of the game ball reaching the flow path formed between the top plate portion and the rail portion.

  The distribution means guides the game ball that has passed through the passage gate portion and reached the flow path and is supported by the top plate portion in a target direction or a direction other than the target, with a specific position of the top plate portion as a boundary. Sort as you do.

  As a result, among the previous game balls that have passed through the passage gate portion, the previous game balls that have a factor such that the space between the next game ball and the subsequent game ball that should be guided in the target direction becomes clogged together. Can be eliminated by guiding in a direction other than the intended direction.

  According to a second aspect of the present invention, in the first aspect of the present invention, the distribution means is configured such that, as the target direction, the game ball that has passed through the passage gate with a firing strength of a predetermined value or more is the top plate. The game ball is guided to the right end of the top part, and the game ball that has passed through the passage gate with a firing intensity less than a predetermined value is guided to the left end of the top board part as a direction other than the purpose.

  The distribution means guides the game ball that has passed through the passage gate with a firing strength of a predetermined value or more to the right end of the top plate portion. The game ball guided to the right end of the top plate is a so-called “right-handed” game ball, which is the direction of the object of the present invention.

  In addition, the game ball that has passed through the passage gate with a launch intensity less than a predetermined value is guided to the left end of the top plate portion. The game sphere guided to the left end of the top plate is a game sphere equivalent to so-called “left-handed” and is in a direction other than the object of the present invention.

  According to a third aspect of the present invention, in the first or second aspect of the invention, the specific position defines a specific launch intensity within a range of launch intensity passing through the passage gate portion, and the specific position is determined. It is characterized by being a landing point on the top plate portion of a game ball launched under a launch intensity of.

  A specific position is determined by determining a specific launch intensity from within the range of the launch intensity that passes through the passage gate, and setting the landing point on the top of the game ball launched under the specific launch intensity as the specific position. Can be set easily.

  The specific position is preferably finely adjusted after setting by calculation or the like, for example, by performing an experiment and repeating trial and error.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects of the present invention, the allocating means has a low level on the upstream side in the flow direction of the launched game ball and a high level on the downstream side. It is a step part.

  By providing the step portion, it is possible to reliably distribute the flow of game balls with the simplest structure.

  As described above, in the present invention, at the uppermost part of the game board in which a flow path is formed between the arc-shaped rail provided at the periphery of the game board and the accessory provided at the center of the game board, Thus, the game balls that are sent one after another have an excellent effect that the game balls can be sent out while maintaining a balance between the game balls within a certain allowable range with respect to the period when the balls are sent.

(Game board configuration)
FIG. 2 shows a configuration of the game board 18 applicable to the present embodiment. The present invention is not limited to the configuration of the game board 18.

  The game board 18 shown in FIG. 2 has a resin sheet-like cell attached to a plywood board serving as a substrate, and the surface of the cell is a board surface. An arc-shaped outer rail is provided near the outer peripheral edge of the board surface. 102 and the inner rail 104 are attached. A transparent acrylic plate or the like may be used instead of the veneer plate. In the circular region surrounded by the outer rail 102 and the inner rail 104, the game ball PB launched and driven from the launching device 165 (see FIG. 3) that operates in accordance with the operation amount of the grip unit 26 has its own weight. The area can be moved by dropping, and this area is a game area in which a game is played.

  In the game area of the game board 18, nails 19 (partial indices) are scattered and driven, and a windmill 21 is attached. In addition, a center accessory 105 is arranged almost in the center of the game area. Various movable members and decorative members are attached to the center accessory 105 according to game specifications. For example, the center accessory 105 according to the present embodiment includes the movable accessory devices 105A, 105B, and 105C that operate mechanically, and a display unit 106 that displays images such as various effects. Although the detailed description of the movable accessory devices 105A, 105B, and 105C is omitted, the operation of the front of the display unit 106 as an operation for giving the player a sense of expectation of winning based on the result of the special symbol lottery described later. Operation effects such as projecting (see hatched arrows G1, G2, and G3 in FIG. 2) and widening or narrowing the display surface of the display unit 106 are executed. On the other hand, an LCD display, an LED display, or the like can be applied to the display unit 106, but it is not particularly limited to the display form.

  In the display unit 106, for example, a symbol variation pattern effect for informing the result of the special symbol lottery is executed (see arrows ZL, ZC, ZR in FIG. 2). As an example, if the symbol pattern of 3 columns is individually changed, and the symbol pattern when 2 of the symbol columns are stopped changing, the symbol becomes the same symbol. The final row stops the symbol variation, and if the stop symbol becomes the same symbol as the two rows of symbols that have already stopped, the winning is notified, and if it becomes a different symbol, a loss is notified. .

  A stage 105 </ b> S is formed on the lower side of the center accessory 105. A game ball PB received by rebounding with a nail 19 or the like, or a game ball PB received guided by a warp path (not shown) is sent to the stage 105S.

  The stage 105S is formed with an inclined surface, a protrusion, etc., and the movement of the game ball PB changes irregularly by the inclined surface, the protrusion, etc., and finally returns to the game board 18 from the lower side. ing.

  As shown in FIG. 2, a flow path in the normal game is formed on the left side of the center accessory 105, and a passage gate 118A is provided.

  In addition, a start winning hole combination 130 is arranged below the center combination 105, and special symbol start winning holes 130A and 130B are arranged so as to be connected vertically. The special symbol start winning opening 130A is open at the top so that it can always win.

  It should be noted that even if the special symbol start winning holes 130A and 130B are game balls PB that reach from the flow path in the normal game (the left flow path of the center game 105), the flow path (the center game 105 in the special game) in particular. Even the game ball PB reaching from the right channel) is provided at a position where winning can be achieved.

  On the other hand, the upper part of the special symbol start winning opening 130B is normally closed by the special symbol start winning opening 130A.

  An electric tulip 136 is attached to the special symbol start winning opening 130B. The electric tulip 136 is configured to open and close by energization / non-energization of an electric chew solenoid 138 (see FIG. 3) disposed on the back side of the game board 18.

  The electric tulip 136 is opened when the normal symbol lottery is won. When the electric tulip 136 is in the open state, the game ball PB can be received in the winning opening of the special symbol start winning opening 130B, and the game ball PB can be won.

  A center attacker 112 </ b> A that is opened at the time of the big winning of the special symbol lottery is arranged below the start winning prize combination 130.

  Further, at the lowest position of the game area of the game board 18, there is provided an out port 124 through which the dislodged ball is discharged to the back side of the game board 18.

  On the other hand, as shown in FIG. 2, a passing gate 118B having a normal symbol lottery starting function is disposed on the right side of the center accessory 105 in FIG.

  A right attacker 112B that is opened at the time of a big win in the special symbol lottery is arranged at a position lower than the passing gate 118B and guided by the nail 19 or the like.

  Note that the proper use of the center attacker 112A and the right attacker 112B is determined by the game specifications, and usually one of them is selected and the opening operation is performed.

  The center attacker 112A is provided with an opening / closing door 116A. This open / close door 116A is opened or closed by energization / non-energization of an attacker solenoid 148A (see FIG. 3). When the opening / closing door 116A is opened, the game ball PB dropped on the opening / closing door 116A is guided by the opening / closing door 116A and wins the center attacker 112A.

  The right attacker 112B is provided with an opening / closing door 116B. The opening / closing door 116B is opened or closed by energization / non-energization of the attacker solenoid 148B (see FIG. 3). When the opening / closing door 116B is opened, the game ball PB dropped on the opening / closing door 116B is guided by the opening / closing door 116B and wins the right attacker 112B.

  Here, when the game ball PB wins the special symbol start winning port 130A or the special symbol start winning port 130B, the special symbol lottery is executed.

  When the special symbol lottery is won, the open / close door 116A or 116B of the center attacker 112A or the right attacker 112B is opened and closed in a predetermined pattern, and this is repeated a predetermined number of times (predetermined rounds). Such a game state that is clearly advantageous to the player is referred to as “special game”, “big game processing”, etc., and is distinguished from the normal game state.

  Note that the winning (“big hit”), which is the lottery result of the special symbol lottery, is mainly notified in the symbol variation display effect of the display unit 106, and in the case of the symbol variation display effect or during the major role processing, the lottery is performed. The notification of the result is on standby (holding / storing), and the notification is made sequentially. In addition to the symbol variation display effect, a character such as an anthropomorphic animal is displayed, and a visual effect is given to give the player a sense of expectation by implying that they have won the special symbol lottery. In this case, the player's interest is increased by sound effects.

  Here, in the normal game state, the player rotates the grip unit 26 and adjusts the firing strength to strike the left side of the center accessory 105 (so-called “left-handed state”). On the other hand, in the special game state (during the big game process), the player rotates the grip unit 26 to aim the right side in FIG. 2 with respect to the center actor 105 toward the center attacker 112A or the right attacker 112B. The firing strength (so-called “right-handed state”) is adjusted. In addition, there may be a specific gaming state (for example, a “right-handed state” aiming at the passing gate 118B in the case of a normal game for a certain period of time after a special game (main role processing)).

  When the game ball PB passes through the passing gate 118B in the specific gaming state, the normal symbol lottery is executed, and when the normal symbol lottery is won, the electric tulip 136 is released. In the specific gaming state, the opening period of the electric tulip is longer than the opening period of the gaming state other than the specific gaming state, so that the special symbol start winning opening 130B is won as compared to the gaming state other than the specific gaming state. Probability will increase.

  In the present embodiment, the specific game state is “short-time game state with electric tulip 136 support” (sometimes referred to as “short-time with electric support”, “short-time with electric support”, etc.), and with non-electric support. While the base value during the time reduction is about 20, the base value during the time reduction with the electric support is set to be about 90-100.

  The base value is the ratio of the number of prize balls paid out with respect to the number of shot balls. For example, when 100 game balls PB are fired and there are 20 prize balls paid out, the base value is “20”. When a ball is paid out, the base is called “100”.

  The reason why each base value is set to “about” is that the numerical value is a theoretical numerical value, and an error occurs with respect to the theoretical numerical value in an actual game. In the average value of a long game period, it converges to the base value set in each.

  As shown in FIG. 2, the game board 18 has a plurality of general prize openings 120 (in the present embodiment) on the lower side of the center prize 105 and on the left side of the start prize opening role 130 (lower left of the game board 18). In the embodiment, an accessory device 107 provided with two general winning ports 120A and 120B is provided. The number of the general winning openings 120 is not limited to two. For example, the number may be determined by a design calculation such as a basic base and a winning rate.

  In the present embodiment, a maximum of four special symbol start winning openings are provided for one special symbol start winning opening (in this embodiment, two special symbol start winning openings 130A and special symbol start winning opening 130B). Since it is a mouth, it is eight.) Reservation (memory for starting winning of game ball) is possible. The number of reserved balls is not limited.

  The number of reserved balls is mainly determined by a special symbol memory display unit which is a part of the game progress guide lamp unit 109 having a special symbol display unit (located at the lower right when the center accessory 105 shown in FIG. 2 is viewed from the front). Informed. Note that the information regarding the number of holds may be displayed on the display unit 106 in addition to the display on the game progress guide lamp unit 109. In the information regarding the hold on the display unit 106, for example, a pre-reading notice may be performed to change the lighting state (color, shape, blinking, etc.).

(Control system configuration)
As shown in FIG. 3, the control system of the pachinko machine 10 according to the present embodiment is configured with a main control unit 150 as a center. The main control unit 150 includes an effect control unit 152 and a payout control unit. 154 is connected. The main control unit 150 stores a basic program relating to games, and the operation of each unit is controlled based on a command signal from the main control unit 150.

  Information indicating the progress of the game (start winning signal, jackpot signal, symbol determination number signal, etc.) is transmitted from the main control unit 150 to the hall computer (not shown) via the board external terminal 190.

  The main control unit 150 includes, as an input system, pass gate sensors 118AS and 118BS that detect game balls PB that pass through the pass gates 118A and 118B, and a special figure A start port that detects a winning ball to the special symbol start winning port 130A. Sensor 130AS, special figure B start opening sensor 130BS for detecting a winning ball to the special symbol starting winning opening 130B, an attacker A sensor 112AS for detecting a winning ball to the center attacker 112A that is opened at the time of “hit”, a right attacker 112B An attacker B sensor 112BS for detecting a winning ball and a general winning sensors 120AS and 120BS for detecting a winning ball to the general winning ports 120A and 120B are connected.

  In addition, the main control unit 150 includes, as an output system, a guide lamp unit 109 for informing game information and a game state by a lamp lighting state, an electric chew solenoid 138 for opening / closing the electric tulip 136, and an opening / closing door 116A of the center attacker 112A. An attacker solenoid 148A for opening / closing and an attacker solenoid 148B for opening / closing the opening / closing door 116B of the right attacker 112B are connected.

  The operation control unit 50 is connected to the effect control unit 152 as an input system. In addition, the effect control unit 152 includes, as an output system, a light source 137 for illumination effects provided in various game parts of the pachinko machine 10, speakers 60L, 60R, 60B, and a movable accessory device 105A in the center accessory 105. A center accessory driving system 111 for operating ~ 105C is connected.

  Furthermore, the display unit 106 is connected to the effect control unit 152 via the symbol control unit 156.

  The payout control unit 154 is connected to a payout device 160 and a launch control unit 164, and the launch control unit 164 is connected to a launch device 165. The payout control unit 154 operates the payout device 160 provided in the pachinko machine 10 to control the payout and lending ball payout and stop operations and the number of payouts. Further, the launch control unit 164 activates the launch device 165 by the operation of the grip unit 26 (see FIG. 1) by the player, and starts launch of the game ball PB and the launch intensity according to the operation amount of the grip unit 26. To control.

  Further, the payout control unit 154 transmits payout information to a hall computer (not shown) installed in the hall via the frame external terminal 191.

(Ceiling structure of the center object 105)
As described above, the firing strength of the game ball PB can be adjusted by operating the clip unit 26. For example, in a normal game, so-called “left-handed” is generally used, so the player can use a nail 19S (hereinafter referred to as “specific nail 19S”) located slightly to the left of the top of the ceiling of the center accessory 105. The game ball PB is fired with a launch strength that does not exceed. As a result, the game ball PB comes into contact with the surrounding nails 19 including the specific nail 19 </ b> S and falls through the flow path on the left side of the center accessory 105.

  On the other hand, for example, in the case of a big game process, so-called “right-handed” is executed.

  The player launches the game ball PB with a launch intensity that strikes to the right of the top of the top board portion 200 (see FIGS. 2 and 4) of the center accessory 105. Normally, by operating the grip unit 26 with the maximum operation amount (maximum rotation angle in the case of a rotation operation), the game ball PB slides without being separated from the outer rail 102 by a so-called centrifugal force, Guided to the right channel of the center actor 105.

  Note that the “right-handed” gaming ball PB comes into contact with the buffer member 113 shown in FIG. 2 and falls to the right side of the center accessory 105 in a state where the ball force is attenuated. Note that a ladder-like unevenness may be provided on the right wall of the center accessory 105 to further attenuate the falling speed of the falling game ball PB.

  Incidentally, as shown in FIG. 5, the operation amount of the grip unit 26 substantially follows the firing intensity, and there is a threshold value T for determining whether or not to pass the “specific nail 19 </ b> S” described above.

  In other words, if it is within the range of the firing intensity Rmin exceeding the threshold to the maximum manipulated variable firing intensity Rmax, at least the “specific nail 19S” is exceeded.

  However, when the game ball PB that exceeds the “specific nail 19S” is close to the launch strength Rmin, the ball does not have momentum, and therefore the ball deviates from the outer rail 102 and falls to the top plate portion 200 of the center accessory 105. There is.

  Since the top plate portion 200 is an upwardly convex circular arc surface, the game ball PB falling on the top plate portion 200 has the momentum of the game ball PB and the tangential slope of the drop point (positive or negative with respect to the horizontal). Depending on the inclination angle).

  Accordingly, the movement speed of the game ball PB may be temporarily attenuated due to the balance between the momentum of the game ball PB and the tangential slope of the falling point, and the game that has been launched next to the attenuated game ball PB. When the ball PB is close to the firing strength Rmax, the game balls PB may be linked together.

  When there is a change in the balance between the game balls PB with respect to the launch cycle (especially when connecting a rosary), the sphere was connected immediately before reaching the maximum number of winning balls of the center attacker 112A and the right attacker 112B. There may be a case where the game ball PB reaches and wins more than the design value predicted to arrive at a certain period.

  Therefore, in the present embodiment, as shown in FIG. 4, a step 202 is provided on the top plate portion 200 of the center accessory 105, and basically falls outside the outer rail 102 and falls on the top plate portion 200. The game balls PB to be played are all distributed to the left side of the center accessory 105.

  FIG. 4 is an enlarged view of the top plate portion 200 of the center accessory 105 in which requirements that serve as design criteria for constructing the stepped portion 202 are described.

  The stepped portion 202 is constructed by the following procedure. The following procedure is an example, and the present invention includes, for example, determining the position of the stepped portion 202 by experiment (trial and error). Further, this experiment may be used as a fine adjustment after setting by the following procedure.

  As shown in FIG. 4, the radius rr of the outer rail 102 is an arc surface concentric with the radius ry of the arc surface of the top plate portion 200 (partially shown by a two-dot chain line) before the stepped portion 202 is provided.

(Procedure 1)
Based on the dimension A between the “specific nail 19S” and the outer rail 102, the firing strength Rmin in FIG. 5 is determined. In other words, the firing strength Rmin is determined by the dimension A between the “specific nail 19S” and the outer rail 102.

(Procedure 2)
Although the launch strength Rmin exceeds the “specific nail 19S”, the vicinity of the point B that is a horizontal tangent line on the top plate portion 200 becomes the drop point, and even if it is guided to the right side of the center accessory 105, the flow velocity is Slow down.

  As shown in FIG. 6, the degree of deceleration is the highest in the firing strength Rmin and the lowest in the firing strength Rmax. A firing strength Rmid at which a degree of deceleration is allowed is determined between the firing strength Rmin and the firing strength Rmax.

  If the launch strength Rmid is equal to or greater than the launch strength Rmid, the game ball PB flows to the right side of the center accessory 105 without decelerating, and does not cause the occurrence of the above-described rosary connection.

(Procedure 3)
Based on the firing strength Rmid determined in the procedure 2, the drop point C at the top plate 200 is calculated.

(Procedure 4)
A stepped portion 202 having a size larger than the radius of the game ball PB is provided at the drop point C calculated in step 3 (preferably, a position moved to the right side of the drop point C by an offset amount α about the radius of the game ball PB). And a slope 204 is formed on the left side of the stepped portion 202 so as to descend to the left.

  As a result, a part of the game balls PB falling on the top board portion 200 (game balls PB fired with a launch strength weaker than the launch strength Rmid) all fall before the step portion 202 and follow the slope 204. It will be guided to the left side of the center actor 105.

  As described above, the stepped portion 202 set by the steps 1 to 4 is only a reference, and the stepped portion 202 on the left side of the drop point C is based on the allowable range of the deceleration degree of the game ball PB. It is also possible to provide.

  The operation of this embodiment will be described below.

(Game specifications)
First, the flow of the game based on the game specifications in the pachinko machine according to the present embodiment will be described. This game specification is not a limiting element of the present invention, and can be applied to other game specifications that may instruct a right-handed strike.

  In the game using the pachinko machine 10, when the player operates the grip unit 26, the ball is shot upward by the launching device 165 one by one. Note that the firing period is based on less than 100 balls per minute, and is approximately 6 seconds / ball by simple calculation.

  In a normal game, a game ball PB that is launched while being adjusted to a so-called “left-handed” launch intensity is slid on the outer rail 102 between the outer rail 102 and the inner rail 104 by a so-called centrifugal force. The game area is driven away from the outer rail 102 by the launch strength, guided to the left flow path of the center accessory 105, and falls within the game area while changing the direction of contact with the nail 19 or the windmill 21.

  In the so-called “left-handed” game (ordinary game), the game ball PB is led to the start winning hole accessory 130, and when the special symbol start winning opening 130A or 130B is won, a special symbol lottery is executed. The game ball PB that has reached the lower end of the game area without winning a prize is collected into the pachinko machine 10 from the out port 124.

  In addition, when the firing strength is strong, the outer rail 102 may be slid after being driven into the game area and guided to the upper and right flow paths of the center accessory 105 (see “Right-handed” described later). ”For details).

  In the special symbol lottery, the player is notified of the lottery result by the symbol variation pattern effect (arrows L, ZC, and ZR in FIG. 2 mean that the symbol is changing) executed on the display unit 106. . The symbol variation pattern effect is executed by selecting a symbol variation pattern type from the symbol variation pattern selection table based on an instruction signal from the main control unit 150 or the like.

  When the special symbol lottery is won, the opening / closing door 116A or 116B of the center attacker 112A or the right attacker 112B is opened for a predetermined time and a predetermined number of times, and a big role process is executed to dramatically increase the winning of the game ball from the normal gaming state. The

  Unlike the above-described normal game, this big game process is a so-called “right-handed” game.

  That is, by adjusting the firing strength of the game ball PB so that it passes through the right side of the game board 18 with the center role 105 as a boundary, obstacles (including the wall of the role) such as the nail 19 and the windmill 21 are adjusted. While abutting, the game ball is guided to the center attacker 112A or the right attacker 112B.

  Next, when the big character process is completed, there are a case where the left-handing is returned and a case where the right-handing is continued. If the right-hand stroke is continued, the special symbol start where the electric tulip 136 is open is aimed at the passing gate 118B in which the normal symbol lottery is in a short time state (substantially, the opening time of the electric tulip 136 is extended). The game ball is guided to the winning opening 130B. That is, when the game ball PB passes the passing gate 118B, the normal symbol lottery is executed in a short time state, and if the winning (for example, the winning probability 1 / 1.1) is achieved, the electric tulip 136 is frequently opened, and the opening time is By extending, it becomes possible to win a special symbol start winning opening 130B (ordinary game for a specific period). When the game ball PB wins the special symbol start winning port 130B, the special symbol lottery is executed in the same manner as the special symbol start winning port 130A. Depending on the result of the special symbol lottery, the big game process is continued ("right-handed") or the normal game is returned ("left-handed").

(Step part)
In the present embodiment, a stepped portion 202 is provided on the top plate portion 200 of the center accessory 105, and the left and right sorting of the game balls PB that arrives according to the firing strength is clarified.

  In forming the stepped portion 202, first, the firing strength Rmin in FIG. 5 is determined based on the dimension A between the “specific nail 19S” and the outer rail 102 (procedure 1).

  Next, a firing strength Rmid in which the degree of deceleration is allowed is determined between the firing strength Rmin and the firing strength Rmax in FIG. 6 (procedure 2).

  Based on the firing strength Rmid determined in the procedure 2, the drop point C at the top panel 200 is calculated (procedure 3), the step 202 is provided at the drop point C (preferably, the drop point C + α), and the step On the left side of 202, a slope 204 is formed on the left shoulder downward (procedure 4).

  The height of the stepped portion 202 is preferably equal to or greater than the radius of the game ball PB (for example, the diameter of the game ball PB is about 6 mm with respect to 11 mm).

(Trends in game balls PB based on launch intensity)
The stepped portion 202 passes through a gap (see arrow A in FIG. 4) between the rail 102 and the “specific nail 19S”, but the momentum is weak, and the stepped portion 202 separates from the rail 102 and the top plate portion 200 of the center accessory 105. The game ball PB falling on the board becomes a boundary for distributing the game ball PB to either the left or right side of the top board 200.

  In other words, the game ball PB exceeding the stepped portion 202 has a relatively strong launch strength (launch strength) within the launch strength range (launch strength Rmin to launch strength Rmax) passing through the gap indicated by the arrow A in FIG. Rmid or higher). Therefore, there is momentum in the sphere, and part of the ball reaches the buffer member 113 without deviating from the rail 102, and the other part reaches the buffer member 113 without falling off the momentum even though it falls to the top plate part 200.

  7 and 8 show the trend of the game ball PB that is “right-handed”.

  FIG. 7 shows a trend of the game ball PB that reaches the buffer member 113 without being deviated from the rail 102 by a so-called centrifugal force and becomes “right-handed”.

  That is, first, the game ball PB passes through the rail 102 and the “specific nail 19S” (see FIG. 7A), and moves while contacting the rail 102 as it is (see FIG. 7B). It passes above the paragraph part 202 while contacting 102 (see FIG. 7C → FIG. 7D).

  FIG. 8 shows a trend of the game ball PB that falls on the top board 200 but is “right-handed”.

  First, the game ball PB passes through the rail 102 and the “specific nail 19S” (see FIG. 8A), and the momentum attenuates and moves away from the rail 102 (see FIG. 8B). It moves while approaching the top plate portion 200 (see FIG. 8C), and drops (landes) on the ceiling surface 200 when it exceeds the paragraph portion 202 (see FIG. 8D).

  On the other hand, since the game ball PB launched with a relatively weak launch strength (less than the launch strength Rmid) within the launch strength range (launch strength Rmin to launch strength Rmax), the ball has no momentum. It falls to the top plate part 200 before the part 202.

  FIG. 9 shows a trend of the game ball PB that falls on the top board 200 and is equivalent to “left-handed”.

  In FIG. 9, when the game ball PB passes the rail 102 and the “specific nail 19S”, the momentum is attenuated (see FIG. 9A), and gradually moves closer to the top plate 200 (FIG. 8 ( B)), it falls (landing) before the paragraph 202 and bounces without exceeding the step 202 (see FIG. 8C), and is guided to the left along the slope of the slope 204.

  As described above, even if the game ball PB is likely to be “right-handed” after passing through the rail 102 and the “specific nail 19S”, the game ball PB is placed on the center object 105 according to the predetermined degree of deceleration. A stepped portion 202 that clearly distributes left and right in the plate portion 200 is provided. As a result, the game ball PB having a momentum is driven in after the game ball staying at a reduced momentum, and the game ball PB is prevented from flowing through the right side of the center accessory 105 by connecting the beads. be able to. This avoidance of the daisy chain can reduce, for example, the chance of winning beyond the maximum number of winning balls determined by each of the center attacker 112A and the right attacker 112B.

  In the present embodiment, the top plate 200 is provided with the stepped portion 202 so that the game balls passed between the rail 102 and the “specific nail 19S” are distributed to the left and right, but the game balls PB are connected in a rosary manner. As long as it is possible to avoid this, the buffer is not limited to the stepped portion 202, and a buffer that temporarily holds the game ball PB intentionally and discharges it at a fixed period may be provided. The buffer may be simply a crank-shaped, S-curve-shaped channel, or a croon-shaped flow path, or may be provided with a mechanism for rotating a star-shaped rotating member with a motor.
