And a passage sensor for detecting the passage of the game ball. And the internal diameter of a ball passage way is the same diameter over the whole passage course through which a game ball passes.

JP 2001-286615 A

In Patent Document 1 described above, the inner diameter of the ball passageway through which the game ball passes is made the same diameter over the entire passage route through which the game ball passes.
For this reason, the configuration of the gaming board is, for example, a configuration in which the passing chucker is arranged on the lower side on the gaming board surface, and the configuration in which a gaming ball such as a nail is in contact with the upper side of the passing chucker is not arranged. In some cases, when the game ball launched on the game board surface enters the passage chucker with almost no deceleration, and the game ball entering the passage chucker passes through the ball passage at high speed, the detection performance of the passage sensor is high. There may be a problem that the speed of the game ball cannot be accommodated and the passage sensor cannot detect the passing of the game ball.

In addition, when a game ball launched on the surface of the game board passes through the ball passage at high speed and the game ball collides with the sensor, there is a possibility that the passing sensor may be broken due to an impact received from the game ball. is there.
Therefore, the present invention has been made paying attention to such unsolved problems of the conventional technology. An object of the present invention is to provide a gaming machine capable of decelerating the speed of a game ball detected by a passage sensor from the speed at the time of entering a passage chucker.

[Invention 1] In order to achieve the above object, a gaming machine of Invention 1 includes a ball passage that allows a game ball to pass in the vertical direction, a passage sensor that detects passage of the game ball through the ball passage, A game machine having a passage chucker provided in a game area of a game board, and performing a lottery triggered by detection of the passage of the game ball by the passage sensor,
A minimum width of a portion of the ball passage path above the passage sensor viewed from the direction in which the game ball enters the passage chucker is less than the diameter of the game ball.

With such a configuration, the minimum width seen from the direction in which the game ball enters the passage chucker in a portion above the passage sensor in the ball passage path through which the game ball can pass in the vertical direction is equal to that of the game ball. It is less than the diameter.
Thus, the game ball entering the passage chucker can be brought into contact with the minimum width portion of the ball passage before the passage sensor detects, so that the speed of the game ball detected by the passage sensor is determined by the passage chucker. It becomes possible to decelerate from the speed at the time of entering.

[Invention 2] Furthermore, the gaming machine of Invention 2 is as follows. That is, the gaming machine according to the first aspect of the present invention includes an upper inner rib that is provided in a portion of the ball passageway above the passage sensor and protrudes toward the center of the ball passageway.
And, the upper inner rib is such that the minimum width seen from the direction in which the game ball enters the passage chucker is less than the diameter of the game ball above the passage sensor in the ball passage. Projecting toward the center of the ball passage.

With such a configuration, the upper inner rib that is provided in the portion above the passage sensor in the ball passage and protrudes toward the center of the ball passage is above the passage sensor in the ball passage. This portion projects toward the center of the ball passage so that the minimum width seen from the direction in which the game ball enters the passage chucker is less than the diameter of the game ball.
As a result, the game ball entering the passage chucker can be brought into contact with the upper inner rib before the passage sensor detects, so the speed of the game ball detected by the passage sensor is set at the time of entry into the passage chucker. It becomes possible to decelerate from the speed.

[Invention 3] Furthermore, the gaming machine of Invention 3 is as follows. That is, in the gaming machine according to the second aspect, the upper inner rib projects laterally along the gaming board surface of the gaming board.
In such a configuration, the upper inner rib protrudes laterally along the game board surface of the game board, so the front frame on which the game board is provided and the front side of the front frame are provided. Without the need for adjustment such as increasing the distance to the front door, the shape of the upper inner rib is changed from the direction in which the game ball enters the passage chucker through the portion of the ball passageway above the passage sensor. It becomes possible to make it the shape where the minimum width | variety seen becomes less than the diameter of a game ball.
Thereby, by changing only the configuration of the passing chucker from the conventional gaming machine, the speed of the game ball detected by the passing sensor is changed from the speed at the time of entering the passing chucker without changing the configuration of the gaming board. It becomes possible to decelerate.

[Invention 4] Furthermore, the gaming machine of Invention 4 is as follows. That is, in the gaming machine of the invention 3, the ball passing path is provided in a portion below the passing sensor and protrudes toward the upper inner rib as viewed from the direction in which the gaming ball enters the passing chucker. A lower inner rib is provided.
The lower inner rib is such that the shortest distance viewed from the direction in which the game ball enters the passing chucker between the upper inner rib and the lower inner rib is less than the diameter of the game ball. , Projecting toward the upper inner rib as viewed from the direction in which the game ball enters the passing chucker.

If it is such composition, a lower inner rib which is provided in a portion below the passage sensor in the ball passage and projects toward the upper inner rib as seen from the direction in which the game ball enters the passage chucker. As seen from the direction in which the game ball enters the passage chucker so that the shortest distance seen from the direction in which the game ball enters the passage chucker between the upper inner rib and the lower inner rib is less than the diameter of the game ball. Projects toward the upper inner rib.
Thereby, it is possible to approximate the lateral position of the game ball entering the passing chucker and the lateral position of the game ball discharged from the passing chucker.

According to the present invention, the game ball entering the passing chucker can be brought into contact with the minimum width portion of the ball passage before the passing sensor detects, so the speed of the gaming ball detected by the passing sensor can be reduced. It becomes possible to decelerate from the speed at the time of entering the passing chucker.
Thereby, it is possible to suppress the occurrence of a situation where the detection performance of the passage sensor cannot correspond to the speed of the game ball, and to suppress the occurrence of a situation where the passage sensor cannot detect the passage of the game ball. In addition to this, when a game ball passing through the ball passageway collides with the passage sensor, it is possible to reduce the impact that the passage sensor receives from the game ball, so when the game ball passes through the ball passageway It is possible to reduce the possibility that the passage sensor will fail.

Is set to Here, the minimum width Wmin is a straight line connecting the upper left inner rib IRLH and the upper right inner rib IRRH described later in the shortest distance as viewed from the direction (upward) in which the game ball enters the passing chucker 160, A straight line passing through the center of the gate hole 166 is shown. In the present embodiment, a case where the diameter of the game ball is set to 11 [mm] which is a general value will be described.

In the present embodiment, as an example, a case where the protrusion amount of the upper left inner rib IRLH is set to 2 [mm] will be described.
The reason why the protruding amount of the upper left inner rib IRLH is set to 2 [mm] is that when the diameter of the game ball is 11 [mm], the protruding amount of the upper left inner rib IRLH exceeds 2 [mm]. If the value is set, there is a possibility that the game ball is likely to stop (ball clogging occurs) between the left lateral plate portion 170 and the right lateral plate portion 172, and the game ball that has entered the passing chucker 160. This is because the impact force applied to the upper left inner rib IRLH may increase.

The lower left inner rib IRLL protrudes from a position below the sensor mounting opening 168b on one surface of the left lateral plate 170 toward the vertical line L passing through the center of the gate hole 166, When viewed from the front (front of the game board 100), the sensor mounting opening 168b is disposed below.

The case where the minimum width Wmin of the ball passage viewed from the direction in which the ball enters is less than 11 [mm] will be described.

The lower right inner rib IRRL is directed from a position below one of the surfaces of the right lateral plate portion 172 to the lower left inner rib IRLL toward the vertical line L passing through the center of the gate hole 166. It protrudes and is disposed below the sensor mounting opening 168b when viewed from the front (front of the game board 100).
That is, the lower right inner rib IRRL is located downstream of the first starting gate switch 200 in the passage path of the game ball in the portion of one surface of the right lateral plate portion 172 that faces the passage path of the game ball. It is provided and protrudes toward the upper left inner rib IRLH when viewed from the direction orthogonal to the radial direction of the gate hole 166.

In the lower right inner rib IRRL, the shortest distance between the upper left inner rib IRLH and the lower right inner rib IRRL viewed from the direction in which the game ball enters the passing chucker 160 is less than the diameter of the game ball.

(About special symbol lottery)
Next, with reference to FIGS. 1 to 4, a special prize state that occurs when a special symbol lottery is won will be described with reference to FIG. 5.
FIG. 5 is a diagram showing the types of prescribed special prize states.
In the gaming machine 1 of the present embodiment, as shown in FIG. 5, four types of “special bonus”, “probability 1 big win”, “probability 2 big win” and “small win” are defined as the types of special prize states. Yes.
The main control device 220 performs display control so that the special symbol display device 146 stops and displays the special symbol at the “normal winning symbol” when the “normal winning symbol” is won.

At this time, the effect control device 240 performs display control in the effect symbol display device 104 so that the effect symbol is stopped and displayed at “normal hit symbol”.
Here, when the “normal winning symbol” is stopped and displayed on the effect symbol display device 104, for example, “2, 2, 2” in the first display region R1, the second display region R2, and the third display region R3. The effect design is stopped and displayed by a combination of even numbers such as “”.

In addition, when the “ordinary big hit” is won, the number of rounds at the time of winning is 15 times, and in the 100 lotteries after winning (changed display of effect symbols), a short-time state occurs. Further, when the “normal jackpot” is won, the gaming state after the end of the special prize state is set to a low probability state.
Here, the low probability state means a gaming state in which the winning probability of the special symbol lottery is low (normal probability).

The time-short state means a gaming state in which the variation time of the special symbol and the effect symbol is shortened. In the short-time state, the winning probability of the normal symbol lottery is higher than the normal lottery probability (for example, 10 times), and the opening time of the start winning opening is extended compared to the normal opening time. Is done. Further, in the time-short state, the variation time of the normal symbol is shorter than that in the normal time.
Here, in this embodiment, as described above, in the normal state, the winning probability of the normal symbol lottery executed according to the information signal input from the first start gate switch 200 is set to 1/20, and the second start gate The winning probability of the normal symbol lottery executed in accordance with the information signal input from the switch 202 is 1/300. For this reason, in the present embodiment, as an example, when the short time state is reached, the winning probability of the normal symbol lottery executed according to the information signal input from the second start gate switch 202 is reduced from 1/300 to 1/30. Change to (10 times).

Further, when “probability variation 1 jackpot” is won, the main control device 220 performs display control so that the special symbol display device 146 stops and displays the special symbol with “probability variation 1 symbol”.

The production symbols are stopped and displayed with a combination of odd numbers that are the same.

In addition, when “probability 1 big hit” is won, the number of rounds at the time of winning is 15 times, and a short-time state occurs after winning. Furthermore, when “probability 1 big hit” is won, the gaming state after the winning is set to the probability fluctuation state.
Here, the probability variation state refers to a gaming state in which the winning probability of the special symbol lottery is higher than the low probability state (for example, 10 times the normal probability).

Further, when “probability variation 2 big hit” is won, main controller 220 performs display control so that special symbol display device 146 stops and displays the special symbol with “probability variation 2 symbol”.
At this time, the effect control device 240 performs display control so that the effect symbol display device 104 stops and displays the effect symbol at “probability 2 symbol”.
Here, when “probability 2 symbols” is stopped and displayed on the effect symbol display device 104, for example, “1, 3, 5” in the first display region R1, the second display region R2, and the third display region R3. The production symbols are stopped and displayed with a combination of irregularities such as “”.

  In addition, when winning the “probability 2 big win”, the number of rounds at the time of winning is 2 times, and the period of one round (opening time of the big prize opening) is shorter than the “normal big win” (number [About ms]) is set. In addition, when “winning probable big 2” is won, a short-time state does not occur after winning, and the gaming state after winning is set to a probability fluctuation state.

When the “small hit” is won, the main controller 220 performs display control so that the special symbol display device 146 stops and displays the special symbol as “small hit”.
At this time, the effect control device 240 performs display control so that the effect symbol display device 104 stops and displays the effect symbol as “small hit symbol”.
Here, when the “small hit symbol” is stopped and displayed on the effect symbol display device 104, for example, “1, 3, 5” in the first display region R1, the second display region R2, and the third display region R3. The production symbols are stopped and displayed with a combination of irregularities such as “”.

In addition, when “small hit” is won, the number of rounds at the time of winning is two, and the period of one round is set shorter (about several ms) than “normal big hit”. In addition, when the “small hit” is won, a short time state does not occur after winning, and the gaming state after the winning is set to the same gaming state as the winning gaming state.
Here, the opening operation of the big prize opening in each round continues until a predetermined time (for example, 30 [s]) elapses or a predetermined number (for example, 10) of game balls enter. . Also, the opening operation of the special winning opening at the time of winning is repeatedly performed for the number of rounds set according to the type of the special gaming state.

Further, in the case of “missing”, the main control device 220 performs display control so that the special symbol display device 146 stops and displays the special symbol as “missing symbol”.
At this time, the effect control device 240 performs display control so that the effect symbol display device 104 stops and displays the effect symbol at the “out of symbol”.
Here, when the “designated symbol” is stopped and displayed on the effect symbol display device 104, for example, “1, 1, 2” in the first display region R1, the second display region R2, and the third display region R3. The effect design is stopped and displayed by an irregular combination with no regularity.
Note that the type of the special prize state is not limited to the above-described type, and may be configured to include other types. Moreover, it is not necessary to provide all the types of special prize states described above, and each special prize state type may be individually combined according to the characteristics of the gaming machine.

(About control commands)
Next, control commands output from the main control device 220 to the effect control device 240 will be described with reference to FIGS. 1 to 5 and FIG.

It consists of an event (EVENT) which is digital data of byte length.

Main controller 220 outputs a strobe signal (DUSTB) to effect controller 240 when transmitting the control command.
Specifically, main controller 220 transmits mode data triggered by the first rise of the strobe signal, and then outputs event data triggered by the second rise of the strobe signal.

At this time, the effect control device 240 generates an interrupt process in response to the reception of the strobe signal, and stores the control command in the effect control side RAM 244 by this interrupt process.
Control commands output from the main control device 220 to the production control device 240 include a state designation command, a variable time designation command, a symbol stop designation command, a special game state, as shown in the “Function” column in FIG. There are a start designation command, a special gaming state end designation command, a demonstration screen display designation command, and the like.

The state designation command is a command for designating a special symbol lottery result (a win type in the case of winning). Specifically, the state designation command designates any one of “normal jackpot”, “probability change 1 big win”, “probability change 2 big hit”, “small hit”, and “out of place” as a result of the special symbol lottery.
The variation time designation command is a command for designating the variation display time (variation time) of the effect symbol. In the present embodiment, a case where n types (n = 68) of variation times (for example, 2 [s], 30 [s], 120 [s], etc.) are set as the variation times will be described. Therefore, in the present embodiment, the variation time designation command is a command that designates one of the n types of variation times.

The state designation command and the variation time designation command are output at the start of the variation display of the effect symbol. At this time, first, a state designation command is output, and then a change time designation command is output. Here, the start of the variation display of the effect symbol substantially coincides with the start of the variation display of the special symbol.
The symbol stop designation command is a command for designating the stop display of the effect symbol. The symbol stop designation command is output when the effect symbol is stopped. Here, the stop display of the effect symbol is substantially the same as the stop display of the special symbol.

The special game state start designation command is a command for designating the start of the special game state. Specifically, the special gaming state designation command designates one of a normal jackpot start, a probability variation 1 jackpot start, a probability variation 2 jackpot start, and a jackpot start. The special game state start designation command is output at the start of the special game state.
The special game state end designation command is a command for designating the end of the special game state. The special gaming state end designation command is output when the special gaming state ends.
The demonstration screen display designation command is a command for designating display of the demonstration screen. Further, the demonstration screen display designation command is output when a state in which the variation display of the effect symbol is not performed is detected for a predetermined time (for example, 30 [s]).

(Game control processing)
Next, a game control process executed by the main controller 220 will be described with reference to FIGS. 1 to 6 and FIG.
The main control side CPU 226 is composed of a microprocessing unit or the like, and operates based on a game control program capable of executing one cycle (for example, 2 [ms]) with a predetermined operation clock (for example, 4 [ms]). The game control program stored in the predetermined area of the control ROM 228 is activated to execute the game control process shown in the flowchart of FIG.
FIG. 7 is a flowchart showing the game control process.

When the game control process is executed by the main control CPU 226, first, the process proceeds to step S100 as shown in FIG.
In step S100, a hit determination random number update process, which is a process for updating various random numbers related to the determination of a game that directly affects a player's profit, is executed.
Here, various random numbers that are directly related to the determination of the appearance, etc., include random numbers used in the lottery for determining whether or not to generate a hit (hereinafter sometimes referred to as “win determined random numbers”), hit type determined random numbers, etc. There is. In the hit determination random number update process, the hit determination random number value cannot be easily predicted by changing the initial value every time the hit determination random number makes a round.

Next, the process proceeds to step S102, where an effect control random number update process for updating the effect control random number (for example, variation time determination random number) related to the effect is executed, and the process proceeds to step S104.
In step S104, each switch (first start gate switch 200, second start gate switch 202, start winning port switch 204, central general winning port switch 206, left general winning port switch 208 is connected via the main control side input port 222. , The input processing for inputting the information signal output from the right general winning opening switch 210 and the big winning opening switch 212) is executed, and the process proceeds to step S106.

Here, in the input process, the input of the information signal output from each switch is detected. And when the input of the information signal which each switch output is detected, the information which shows detection is memorize | stored in the predetermined area | region of the main control side RAM230.
In step S106, start information update processing for updating start information is executed, and the process proceeds to step S108.
In the start information update process, it is determined whether or not the information signals output from the first start gate switch 200 and the second start gate switch 202 are input based on the processing result of the input process in step S104. When it is determined that the information signals output from the first start gate switch 200 and the second start gate switch 202 are input, the start information storage update process in the start information storage area of the main control side RAM 230 is executed.

Here, in the present embodiment, up to four pieces of start information can be stored in the start information storage area of the main control side RAM 230.
In the starting information storage update process, it is determined whether or not the number of starting information stored in the starting information storage area of the main control side RAM 230 is “4” or more. If it is determined that the number of stored start information is not “4” or more, a winning random number value, a hit type determining random value, a variable time determining random value, etc. are acquired (lottery) from the corresponding random number counter. Each acquired random number value (starting information) is stored in a predetermined storage unit in the starting information storage area of the main control side RAM 230.

On the other hand, if it is determined that the number of stored startup information (hereinafter referred to as “starting information storage number”) is “4” or more, the series of processes is terminated and the process returns to the original process.
In step S108, a hit determination process is executed, and the process proceeds to step S110. The hit determination process will be described later.
In step S110, a winning process for opening the special winning opening in a predetermined pattern is executed, and the process proceeds to step S112.

In the winning process, a control signal is output to the special winning opening solenoid 262 so that the special winning opening is opened in a predetermined pattern.
In the winning process, a special gaming state start designation command for designating the start of a special gaming state (usually big hit, probability variation 1 big hit, probability variation 2 big hit, small hit) is stored in a predetermined area of the main control side RAM 230. Thereby, in the port output process of step S116 described later, a special gaming state start designation command is output to the effect control device 240 via the main control side output port 224.

  In step S112, prize ball payout management processing is executed, and the process proceeds to step S114. In the winning ball payout management process, based on the processing result of the input process in step S104, the detection signals output by the central general winning opening switch 206, the left general winning opening switch 208, the right general winning opening switch 210, and the big winning opening switch 212 are output. It is determined whether or not is input. When it is determined that the detection signals output from the central general winning award port switch 206, the left general winning award port switch 208, the right general award winning port switch 210, and the large winning award port switch 212 are input, the winning ball payout control device 258 is input. A control command for performing the payout operation of the prize ball is stored in a predetermined area of the main control side RAM 230. As a result, in the port output process of step S116, a control command for performing the payout operation of the winning ball is output to the winning ball payout control device 258 via the main control side output port 224.

In step S114, external information output processing for outputting an external information signal related to game control to the hall computer 264 is executed, and the process proceeds to step S116.
In step S116, the port output process for outputting the control command stored in the main control side RAM 230 is executed via the main control side output port 224, the series of processes is terminated, and the process returns to the original process.
In the port output process, a control command is output to the effect control device 240. At this time, a strobe signal is first output to the effect control device 240, and then a control command including mode data and event data is output.
In the port output process, control signals are also sent to the special symbol display device 146, the normal symbol display device 148, the game state display device 144, the winning ball payout control device 258, the start winning port solenoid 260, the big winning port solenoid 262, and the like. Is output.

(Winning judgment process)
Next, the hit determination process in step S108 will be described.
FIG. 8 is a flowchart showing the hit determination process.
In the hit determination process, when executed in step S108, the process first proceeds to step S200 as shown in FIG.
In step S200, the effect symbol display device 104 determines whether or not the effect symbol is changing. If it is determined that the effect symbol is not changing (No), the process proceeds to step S202. On the other hand, when it determines with the production | presentation symbol being fluctuating (Yes), it transfers to step S214.

In step S202, it is determined whether or not the starting information storage number is “1” or more. If it is determined that the starting information storage number is “1” or more (Yes), the process proceeds to step S204. On the other hand, if it is determined that the starting information storage number is not “1” or more (No), the process is terminated and the process returns to the original process.
In step S204, a winning random number is read from the start information storage area of the main control side RAM 230, and the process proceeds to step S206.

  In step S206, it is determined whether or not the winning random number value read in step S204 matches the winning value, and if it is determined that the read winning random number value matches the winning value (Yes), The process proceeds to step S208. On the other hand, when it is determined that the winning random number value read in step S204 does not match the winning value (No), the process proceeds to step S212.

Here, the main control ROM 228 stores a hit determination table in which the correspondence between the hit determination random number value and the hit value is registered. Then, based on the hit determination table, it is determined whether or not the read hit determination random number value matches the hit value. Thereby, the distinction between “win” and “out of” is determined.
Further, when it is determined that it is “out of”, a state designation command corresponding to “out” is stored in a predetermined area of the main control side RAM 230. Thereby, in the port output process of step S116, the state designation command is output to the effect control device 240 via the main control side output port 224.

In step S208, a hit type determination process for determining a win type is executed, and the process proceeds to step S210.
Here, the main control side ROM 228 stores a hit type determination table in which the correspondence between the hit type determination random number value and the hit type number is registered. In the hit type determination process, the hit type determination random number value of the start information is read, the hit type number corresponding to the read hit type determination random number value is read from the hit type determination table, and the win type is determined.

Further, the state designation command corresponding to the read hit type number is stored in a predetermined area of the main control side RAM 230. Thereby, in the port output process of step S116, the state designation command is output to the effect control device 240 via the main control side output port 224.
In step S210, a per-hour variation time determination process for determining the variation time of the effect symbol is executed, a series of processes are terminated, and the process returns to the original process.
Here, the main control ROM 228 stores a plurality of hit time variation time determination tables set for each combination of the hit type, the current starting information storage number, the current gaming state, and the like. Correspondence between the variation time determination random number value and the variation time number is registered in each per-hour variation time determination table.

  Then, in the hit variation time determination process, first, a hit variation time determination table corresponding to the combination of the hit type number determined in step S210, the current starting information storage number, and the current gaming state is read. Then, the variation time determination random number value of the start information is read, and the variation time number corresponding to the read variation time determination random number value is read from the hit variation time determination table. Thereby, the variation time of the effect symbol is determined.

Further, the variable time designation command corresponding to the read variable time number is stored in a predetermined area of the main control side RAM 230. Thereby, in the port output process of step S116, the variable time designation command is transmitted to the effect control device 240 via the main control side output port 224.
In the hit fluctuation time determination process, the determined fluctuation time is set in the fluctuation time timer. Then, the special symbol display device 146 starts to display the variation of the special symbol and starts measuring the variation time by the set timer.

On the other hand, in step S212, the fluctuation time determination process at the time of losing which determines the fluctuation time of an effect design is performed, a series of processes are complete | finished, and it returns to the original process.
Here, the main control ROM 228 stores a plurality of deviation time variation time determination tables set for each combination of the current start information storage number, the current gaming state, and the like. Correspondence between the fluctuation time determination random number value and the fluctuation time number is registered in each outlier time fluctuation time determination table.

  In the loss variation time determination process, first, a loss variation time determination table corresponding to the combination of the current start information storage number and the current gaming state is read. Then, the variation time determination random number value of the start information is read out, and the variation time number corresponding to the read variation time determination random number value is read out from the variation time determination table for loss time. Thereby, the variation time of the effect symbol is determined.

Further, the variable time designation command corresponding to the read variable time number is stored in a predetermined area of the main control side RAM 230. Thereby, in the port output process of step S116, the variable time designation command is transmitted to the effect control device 240 via the main control side output port 224.
Also, in the fluctuation time determination process at the time of loss, the determined fluctuation time is set in the fluctuation time timer. Then, the special symbol display device 146 starts to display the variation of the special symbol and starts measuring the variation time by the set timer.

On the other hand, in step S214, it is determined whether or not the variation time of the effect symbol has elapsed. If it is determined that the variation time has elapsed (Yes), the process proceeds to step S216. On the other hand, when it is determined that the variation time of the effect symbol has not elapsed (No), the series of processes is terminated and the process returns to the original process.
In step S214, it is determined whether or not the variation time has elapsed based on the variation time timer.
In step S216, a symbol stop process for storing a symbol stop designation command in a predetermined area of the main control side RAM 230 is executed, a series of processes are terminated, and the process returns to the original process.
Thereby, in the port output process of step S116, the symbol stop designation command is output to the effect control device 240 via the main control side output port 224.

(Operation / Action)
Hereinafter, the operation / action of the gaming machine 1 having the above-described configuration will be described with reference to FIGS. 1 to 8 and FIG.
A player who plays a game on the gaming machine 1 operates the launch handle 10 to launch a game ball on the game board surface 102.
Here, in the present embodiment, in the normal state, the winning probability of the normal symbol lottery executed in accordance with the information signal input from the first start gate switch 200 is set to 1/20, and is input from the second start gate switch 202. The winning probability of the normal symbol lottery executed according to the information signal is 1/300.

Therefore, in the following description, a case will be described in which the player first fires a game ball on the game board surface 102 so that the game ball passes through the first normal symbol lottery gate 106.
The game balls launched on the game board surface 102 so as to pass through the first normal symbol lottery gate 106 flow down on the left side of the production symbol display device 104 and move on the game board surface 102 toward the first normal symbol lottery gate 106. To move.

  At this time, for example, as shown in FIG. 9, the game ball moving on the game board surface 102 toward the first normal symbol lottery gate 106 is in front of the effect symbol display device 104, that is, above the passing chucker 160. When the game ball B such as the nail N moves to a space where the structure in contact with the game ball is not arranged, the game ball B comes into contact with the plurality of nails N and enters the passage chucker 160 in a plurality of ways. It will enter the passing chucker 160 at a high speed. FIG. 9 is a diagram illustrating the operation of the gaming machine 1.

In the gaming machine 1 of the present embodiment, the upper left inner rib IRLH included in the gate portion 164 moves from the direction in which the game ball enters the passage chucker 166 through the portion above the first start gate switch 200 in the ball passage. It protrudes toward the vertical line L passing through the center of the gate hole 166 so that the minimum width Wmin seen is less than the diameter of the game ball.
For this reason, the game ball B entering the passing chucker 160 comes into contact with the upper left inner rib IRLH before passing through the gate hole 166 regardless of the direction of entering the passing chucker 160, and therefore the game passing through the gate hole 166. The speed of the ball B is decelerated from the speed at the time of entering the passing chucker 160.

Then, the game ball B that has come into contact with the upper left inner rib IRLH and whose speed is decelerated from the speed at the time of entering the passage chucker 160 passes through the gate hole 166, and the first start gate switch that detects this passage 200 outputs an information signal to the main controller 220.
That is, the game ball B entering the passage chucker 166 contacts the portion of the minimum width Wmin of the ball passage before the first start gate switch 200 detects, so the game ball B detected by the first start gate switch 200 The speed is reduced more than the speed at the time of entering the passage chucker 160.

  As described above, since the speed of the game ball passing through the gate hole 166 is decelerated from the speed at the time of entering the passing chucker 160, the detection performance of the first start gate switch 200 becomes the speed of the game ball B. Occurrence of situations where it is impossible to respond is suppressed. Thereby, the occurrence of a situation in which the first start gate switch 200 cannot detect the passage of the game ball B is suppressed.

Further, since the speed of the game ball passing through the gate hole 166 is decelerated from the speed at the time of entering the passing chucker 160, even if the game ball B collides with the first start gate switch 200, the game ball B The impact received from is reduced. Thereby, the possibility that the first start gate switch 200 is broken is reduced.
Further, in the gaming machine 1 of the present embodiment, the left upper inner rib IRLH, the lower left inner rib IRLL, the upper right inner rib IRRH, and the lower right inner rib IRRL are positioned in the lateral direction of the game ball entering the passing chucker 160. And the lateral positions of the game balls B discharged from the passing chucker 160 are formed to be equal.

Therefore, from the time of entering the passing chucker 160, the game is decelerated, passed through the gate hole 166, detected by the first start gate switch 200, and the game ball B is visually recognized until it is discharged from the passing chucker 160. It becomes possible for a person to visually recognize the moving path of the game ball B as a straight track.
Receiving the information signal output by the first start gate switch 200, the main controller 220 executes the normal symbol lottery with a winning probability of 1/20.

When the normal symbol lottery is won, a control signal is output to the start winning opening solenoid 260, and the closed start winning opening side opening / closing member 124 is driven by the starting winning opening solenoid 260 to be opened, and the starting winning opening is closed. From the state to the open state.
When the start winning opening is in an open state, the player launches the game ball to the right of the effect symbol display device 104 in the game board 100 so that the game ball enters the start winning opening (so-called “right” Strike ").

When a game ball enters the open start winning opening, the start winning opening switch 204 that detects the entry outputs an information signal to the main controller 220. Receiving the information signal output from the start winning port switch 204, the main controller 220 executes a special symbol lottery.
When the special symbol lottery is won, a control signal is output to the big prize opening solenoid 262, and the pair of left and right big prize opening side opening / closing members 134 which are in the closed state are driven by the big prize opening solenoid 262 to be in an open state. The big prize opening is changed from the closed state to the open state.

(Effects of the first embodiment)
The effects of this embodiment are listed below.
(1) In the gaming machine 1 of the present embodiment, the game ball enters the passing chucker 160 through a portion above the first start gate switch 200 in the ball passage path through which the game ball B can pass in the vertical direction. The minimum width Wmin viewed from the direction is less than the diameter of the game ball.
For this reason, the game ball B entering the passage chucker 160 can be brought into contact with the portion of the minimum width Wmin of the ball passage before the first start gate switch 200 detects the first start gate switch 200. It is possible to decelerate the speed of the game ball B detected by the player from the speed at the time of entering the passing chucker 160.

As a result, the situation where the detection performance of the first start gate switch 200 cannot cope with the speed of the game ball B is suppressed, and the situation where the first start gate switch 200 cannot detect the passage of the game ball B is prevented. It becomes possible to suppress.
Thereby, since it becomes possible to improve stability with respect to the detection of the passage of the game ball B by the first start gate switch 200, it is possible to improve the stability of the operation of the gaming machine 1.

In addition, when the game ball B passing through the gate hole 166 collides with the first start gate switch 200, it is possible to reduce the impact received by the first start gate switch 200 from the game ball B. When the sphere B passes through the gate hole 166, it is possible to reduce the possibility that the first start gate switch 200 breaks down.
As a result, it is possible to extend the time during which the first start gate switch 200 can detect the passage of the game ball B with high stability, and to stabilize the operation of the gaming machine 1 over a long period of time. It becomes.

(2) In the gaming machine 1 of the present embodiment, the upper left inner rib IRLH is viewed from the direction in which the gaming ball B enters the passing chucker 160 in the portion above the first start gate switch 200 in the ball passage. It protrudes toward the center of the ball passage so that the minimum width Wmin is less than the diameter of the game ball B.
For this reason, the game ball entering the passing chucker 160 can be brought into contact with the upper left inner rib IRLH before the first starting gate switch 200 detects the game ball B detected by the first starting gate switch 200. The speed can be made lower than the speed at the time of entering the passing chucker 160.

As a result, it is possible to improve the stability with respect to the detection of the passage of the game ball B by the first start gate switch 200, so that the operation stability of the gaming machine 1 can be improved.
In addition to this, it is possible to extend the time during which the first start gate switch 200 can detect the passage of the game ball B with high stability, and to stabilize the operation of the gaming machine 1 over a long period of time. It becomes possible.

(3) In the gaming machine 1 of the present embodiment, the upper left inner rib IRLH, the lower left inner rib IRLL, the upper right inner rib IRRH, and the lower right inner rib IRRL protrude laterally along the game board surface 102. .
For this reason, the shape of each inner rib is changed to the first start gate in the ball passage without requiring adjustment such as increasing the distance between the front frame 4 on which the game board 100 is disposed and the front door 6. The minimum width Wmin viewed from the direction in which the game ball B enters the passing chucker 160 through the portion above the switch 200 can be made to be a shape that is less than the diameter of the game ball B.

As a result, by changing only the configuration of the passing chucker 160 from the conventional gaming machine 1, the speed of the game ball B passing through the gate hole 166 enters the passing chucker 160 without changing the configuration of the gaming board 100. It becomes possible to decelerate from the speed at the point of time.
Thereby, it is possible to suppress an increase in cost and a decrease in manufacturing efficiency, and it is possible to reduce the speed of the game ball B passing through the gate hole 166 from the speed at the time of entering the passing chucker 160. It becomes possible to manufacture a simple gaming machine 1.

(4) In the gaming machine 1 of the present embodiment, the protrusion amount of the upper left inner rib IRLH, the lower left inner rib IRLL, the upper right inner rib IRRH and the lower right inner rib IRRL, and the position where each inner rib is provided are passed. The lateral position of the game ball entering the chucker 160 and the lateral position of the game ball B discharged from the passing chucker 160 are formed to be equal.
Therefore, from the time of entering the passing chucker 160, the game is decelerated, passed through the gate hole 166, detected by the first start gate switch 200, and the game ball B is visually recognized until it is discharged from the passing chucker 160. It becomes possible for a person to visually recognize the movement path of the game ball B as a straight track.

  As a result, it is possible to prevent the player who plays a game on the gaming machine 1 from giving a visually uncomfortable feeling when the game ball B passes the passing chucker 160 and passes through the gate hole 166. It is possible to decelerate the speed of the game ball B to be slower than the speed at the time of entering the passing chucker 160.

(5) In the gaming machine 1 of the present embodiment, one surface of the left lateral plate portion 170 protrudes from a position above the sensor mounting opening 168b toward the vertical line L passing through the center of the gate hole 166. Left upper inner rib IRLH is provided, and on one surface of the right lateral plate portion 172 from a position above a portion facing the left upper inner rib IRLH toward a vertical line L passing through the center of the gate hole 166 A right upper inner rib IRRH is provided.

For this reason, the game ball B that enters the passing chucker 160 from the left side, which corresponds to the majority of the game balls B that move on the game board surface 102 toward the first normal symbol lottery gate 106, is transferred to the upper left inner rib IRLH. On the other hand, it is possible to make contact along one surface of the left lateral plate portion 170.
As a result, it is possible to reduce the impact force of most of the game balls B entering the passing chucker 160 on the upper left inner rib IRLH, and the left lateral plate portion including the upper left inner rib IRLH. It becomes possible to suppress damage to 170.
