Description

  The present invention relates to a gaming machine including a launch rail that guides a game ball fired by a launching means to a game area of a game board, as represented by a pachinko gaming machine.

Conventionally, in a pachinko gaming machine that is representative of this type of gaming machine, when a player rotates the launching handle, the launching solenoid or the like is driven in accordance with the amount of operation of the launching handle of the player and connected to the launching solenoid. The game ball is launched into a game area provided on the game board by causing the game ball at a predetermined launch position to collide with the fire hammer.
The game board is provided with a launch rail to guide the game ball to the game area, and the game ball launched with a launch intensity corresponding to the operation amount of the player's launch handle is connected to the outer launch rail. The game area is guided along a game ball passage formed by two launch rails with an inner (game area side) launch rail.

  However, although the game ball fired in the configuration as described above is guided to the game area via the game ball passage, when the game area finally arrives, the game board and the front door glass plate In the space between them, for example, it reaches the game area from the front (glass plate of the front door) side when viewed from the player side, or the back surface (game board) when viewed from the player side Since the game area is reached from the side, there are many cases where the launch trajectory of the game ball as expected by the player cannot be obtained.

Therefore, as a method of stabilizing the firing trajectory of the game ball to the game area, the rotation amount is increased to increase the rotation amount of the game ball from the base end of the launch rail to the tip end facing the game area. A technique for providing a magnet body as means has been proposed (see, for example, Patent Document 1).
JP 2007-7271 A

However, as disclosed in Patent Document 1, simply providing a magnet body on the launch rail to increase the amount of rotation of the game ball only adds a force to bring the game ball to the launch rail, It is difficult to suppress wobbling in the depth direction.
Therefore, it is desired from the market to provide a gaming machine that suppresses wobbling in the depth direction of a game ball that has been launched into the game area and has a stable launch trajectory. An object of the present invention is to provide a gaming machine that can solve the above-described problems.

(1) In the present invention, a game having launching means for launching a game ball by a player's operation, a game area where the game ball rolls, and a launch rail for guiding the game ball fired by the launch means to the game area An electromagnetic force control for controlling the electromagnetic force of the electromagnet by providing a magnetic member along the launch rail, allowing the game ball to be attracted toward the game board, and using the magnetic member as an electromagnet. And a detecting means for detecting a position in the depth direction of the game ball that is launched by the launching means and travels along the launch rail, and the electromagnetic force control means is configured to detect the game ball of the detecting means. A gaming machine that changes the electromagnetic force of the magnetic member based on the detection position .

  (2) The present invention is characterized in that, in the above (1), the magnetic member is embedded in the game board.

  According to the present invention, the game ball launched by the launching means is always moved to the game board side by the magnetic member provided along the launch rail. Since it is launched into the game area in the attracted state, it is possible to provide a gaming machine with a stable launch trajectory by suppressing fluctuation of the game ball in the depth direction to the game area.

Hereinafter, embodiments of the present invention will be described.
The gaming machine according to the present embodiment includes a launching unit that launches a game ball by a player's operation, a game area in which the game ball rolls, and a launch rail that guides the game ball launched by the launching unit to the game area. And having a magnetic member along the launch rail so that the game ball can be attracted to the game board side.

That is, in the gaming machine according to the present embodiment, when the player manually operates the launching means, the game ball is launched to the game area on the game board with an arbitrary launch intensity. The launched game ball is guided to the upper part of the game area along the game ball guide path formed by the launch rail provided on the game board, and collides with game nails and game members arranged in the game area. While rolling down to the lower part of the game area.
The launching unit is configured to be able to launch a game ball into the game area by a manual operation of the player, for example, with a launch intensity corresponding to an operation amount rotated clockwise (clockwise) when viewed from the player. It is said.

The game area on the game board is provided with a winning opening through which a plurality of game balls can be won, and when a game ball wins, a predetermined number of prize balls are returned to the player. It will be.
In addition, among the winning awards, when a game ball is won in a specific winning opening (for example, a starting opening), a “big hit game” lottery is performed, and when the lottery result is won, The gaming machines are classified into a so-called “first type (digital)” category that generates an advantageous gaming state (big hit game).

In the gaming machine as described above, the player manually operates the launching means and arbitrarily adjusts the firing strength with the aim of increasing the winning rate to the specific winning port (for example, the starting port), After adjusting to the optimum firing intensity, the game is executed while maintaining the manual operation amount of the launching means.
However, in the conventional gaming machine, even if the player maintains the manual operation amount of the launching means having the optimum launch strength, the launch rail that guides the game ball to the game area is finally brought into the game area. The wobbling in the depth direction cannot be prevented at the position to reach, so that the game ball that has reached the game area has a slight change in the collision position with game members such as game nails provided in the game area. In some cases, the player may not be able to maintain the desired firing strength.

Therefore, in this embodiment, by providing a magnetic member on the game board side along the launch rail, it is possible to prevent wobbling in the depth direction at a position where the game ball finally reaches the game area. With the above configuration, the game ball launched into the game area is always ejected to the game area while being attracted by the magnetic force of the magnetic member. This results in a stable collision position with a gaming member such as a nail, and as a result, when the player maintains the amount of manual operation of the launching means, the gaming ball is stabilized at the winning opening that the player in the gaming area aims at. Thus, it is possible to roll down.

The magnetic member may be provided embedded in a game board.
In other words, by embedding a magnetic member in the game board, the magnetic member can be hidden from the player due to the configuration of the game board, and when the game ball passes through the game ball guide path formed by the launch rail. The game ball is stably drawn along the game board while being attracted by the magnetism of the magnetic member embedded in the game board. It is possible to prevent the player from feeling uncomfortable.

  The magnetic member is an electromagnet, and an electromagnetic force control means for performing control to change the electromagnetic force of the electromagnet, and a position in the depth direction of a game ball that is launched by the launching means and travels along the launch rail are detected. And detecting means for changing the electromagnetic force of the magnetic member based on the detection position of the game ball of the detecting means.

In general, the weight of one game ball is specified to be about 5.4 to 5.7 grams, and since the material is an iron steel ball having excellent wear resistance, it is easy to be sensitive to the electromagnetic force of the magnetic material.
As described above, the launching means in the present embodiment can adjust the launching intensity for launching the game ball to the game area on the game board by manually rotating the launching means manually by the player. It is configured.

Therefore, as described above, in a method in which a magnetic member having a fixed electromagnetic force is embedded in the game board and the game ball is drawn toward the game board side, for example, when the firing strength is increased, the electromagnetic force that draws the game ball is drawn. On the other hand, when the firing strength is weakened, the game balls are attracted more than necessary, which may impede the arrival of the game balls to the game area.
Therefore, in the present embodiment, an electromagnet is used for the magnetic member described above, and further, the current supplied to the electromagnet by the electromagnetic force control means is controlled according to the strength of the launching strength of the game ball, so that it corresponds to the firing strength. Electromagnetic force is generated, and the game ball can be stably attracted to the game board side.

Furthermore, as described above, the weight of a single game ball varies somewhat in the range of about 5.4 to 5.7 grams, and the game ball launching means for launching the game ball into the game area also has individual performance. Therefore, even if the player manually operates the launching means with the same amount of rotation, there may be a case where no single launch intensity can be added.
Therefore, in the present embodiment, when the game ball is used as the detection means for detecting the passing position of the game ball in the depth direction when it is fired by the launch means and passes through the game ball guide path formed by the launch rail. By providing in the vicinity of reaching the game area, the electromagnetic force control means corrects the supply current of the electromagnet used as the magnetic member based on the detection result of the passing position of the game ball of the detection means to generate the electromagnetic force. Change it.

That is, by providing a detecting means capable of detecting the passing position of the game ball in the depth direction in the vicinity of the game ball guide path formed by the launch rail near the game area, the passing position of the game ball in the depth direction is provided. For example, when the passing position of the game ball is not stable on the game board side, the electromagnetic force control means causes the current supplied to the electromagnet used as the magnetic member to be higher than the normal current. Control is performed to correct so as to supply more.
Thereby, since the game ball passing through the game ball guiding path is ejected to the game area in a state of being attracted to the game board side by stronger electromagnetic force, at the position where the game ball finally reaches the game area, It is possible to prevent the wobbling in the depth direction.

Here, the electromagnetic force control means is, for example, a control unit including a microcomputer configured with various memories such as a ROM storing a CPU and a control program, a RAM used as a temporary storage means for a work area, and the like. It is good to let the function take on.
At this time, the reference value such as the current supplied to the electromagnet in accordance with the above-described launch strength of the game ball is stored in advance in the ROM or the like, and the electromagnetic force control means passes the game ball in the depth direction. Control for correcting a reference numerical value such as current may be performed in accordance with the detection result of the detection means for detecting the position.

  In addition, for example, the detection unit is configured to be able to detect a passing position of a game ball by providing a plurality of proximity sensors and the like, and the passing signal of the game ball detected by the proximity sensor is directly input to the electromagnetic force control unit, The force control means may perform control for specifying the passing position of the game ball based on the input signal from the proximity sensor and correcting the reference value of the supply current to the electromagnet accordingly.

  By using the gaming machine having the above-described configuration, in the present embodiment, a game ball guide path in which a game ball is formed by a launch rail with a launch intensity corresponding to an arbitrary amount of rotation operation with respect to the launch means by the player. When the game ball is ejected to the game area through the game board, it will always be fired to the game area at a predetermined position on the game board side. It becomes possible to prevent.

(See FIG. 5), by executing control to supply current to the electromagnet 27 according to the firing strength and the passing trajectory of the game ball guide path 30 c of the game ball, the game ball is generated by the electromagnetic force generated by the electromagnet 27. Since it is ejected to the game area 15 while being sucked to the game board 14 side, a game ball is always ejected to the game area 15 from a predetermined position on the game board side.

Here, the description will return to the configuration of the pachinko gaming machine 10 with reference to FIGS. 3 and 4.
The first gaming member 55 is formed in an umbrella shape with the left and right ends positioned below the center, whereas the second gaming member 57 is curved with the left and right ends positioned slightly above the center. It is configured in a formed stage shape, and a part of the game ball that rolls in the game area 15 is temporarily received by the second game member 57, passes through the center of the second game member 57, It flows down toward the starting port 25.

The starting port 25 is defined as the specific winning port in the present embodiment, and is provided below the second gaming member 57 provided substantially at the center of the gaming area 15 and above the large winning port 39 and driven by a solenoid or the like. A blade member 23 is attached as a variable member.
When a game ball that rolls while colliding with the first game member 55 or the game nail 13 installed in the game area 15 wins the start opening 25, a special symbol game and a big win lottery which will be described later are started. In other words, the start port 25 is a specific winning port that triggers a special symbol game and a big win lottery.

  A large winning opening 39 provided below the start opening 25 is provided with a shutter 40 that can be opened and closed on the front side (front). The shutter 40 has a special symbol display 33 (FIG. 4), which will be described in detail later, in which specific numeric symbols are stopped and displayed as special symbols, and the stop display mode is shifted to a jackpot game in which the gaming state is a special game. If it is an aspect that indicates this, it is driven so as to be in an open state in which it is easy to accept a game ball. As a result, the special winning opening 39 is in an open state where it is easy to accept a game ball.

  On the other hand, a count sensor 104 (see FIG. 5) is provided inside the special winning opening 39 provided on the back side (rear) of the shutter 40 to detect a predetermined number (for example, 10) of game balls, or The shutter 40 is driven to the open state until a predetermined time (for example, 30 seconds) elapses. When either a predetermined number of game balls are awarded to the big prize opening 39 or a predetermined time has elapsed in the open state, the shutter 40 is driven to be closed. As a result, the special winning opening 39 is in a closed state in which it is difficult to accept a game ball.

  A game from an open state in which the grand prize opening 39 is in a state where it is easy to accept a game ball to a closed state in which the grand prize opening 39 is in a state in which it is difficult to accept a game ball is called a round game. It is opened during a round game and closed between each round game. In the present embodiment, a game that executes this round game is referred to as a jackpot game. In addition, since the round game is counted as the number of rounds such as “1” round and “2” round, the first round game in the jackpot game may be referred to as the first round and the second round as the second round. .

Subsequently, the shutter 40 driven from the open state to the closed state is driven to the open state again after a predetermined time (for example, 1 second) has elapsed.
Note that a gaming state that continues until the (final) round game that cannot continue from the first round game to the next round game is called a jackpot gaming state. The jackpot gaming state is a very advantageous gaming state for the player because a large number of prize balls can be obtained.

  Further, when a game ball wins or passes through the specific area and the general area in the start opening 25, the general winning openings 56a, 56b, 56c, 56d and the large winning opening 39 described above, it is set in advance according to the type of each winning opening. The number of game balls that have been played are paid out as prize balls to the upper plate 20 or the lower plate 22 which is a game ball storage unit.

In addition, an electrical decoration unit 53 is provided in the vicinity of the lower end of the door 11. As shown in FIG. 4, the electrical decoration unit 53 according to the present embodiment accommodates a special symbol display 33 corresponding to the start port 25 in a display case 37 disposed in the center thereof.
The special symbol display 33 is composed of 7-segment LEDs. This 7-segment LED is activated by turning on / off the 7-segment LED of the special symbol display 33 when a game ball is won at the start opening 25. , 10 numerical symbols from “0” to “9” are variably displayed as special symbols. As described above, a game in which a special symbol is variably displayed and then stopped and the game state varies depending on the result is referred to as a “special symbol game” in the present embodiment.

On both the left and right sides of the display case 37, special symbol holding lamps 33a to 33d corresponding to the start port 25 are provided with the display case 37 interposed therebetween.
The special symbol holding lamps 33a to 33d are displayed on the special symbol display 33 until the special symbol on the variable display is stopped and displayed when the game ball wins the start opening 25 while the variable symbol is already displayed on the special symbol display 33. The number of times that the execution of the special symbol variation display based on the winning of the game ball to the start opening 25 is suspended (so-called “the number of the special symbol reserved balls”) is displayed by lighting. Then, when the special symbol that has been variably displayed is stopped and displayed, variability display of the special symbol that has been suspended is started.

  Specifically, the special symbol hold lamps 33a to 33d are lit in order from the left in correspondence with the number of times the execution of the special symbol variation display is suspended, and the special symbol variation display is temporarily stopped. When the change display of the reserved special symbol is started, the corresponding special symbol hold lamp is turned off. An upper limit is set for the number of times the execution of the special symbol variation display is suspended. For example, the special symbol variation is limited to four times (pieces) per game ball winning in the start opening 25. Display is suspended.

  Also, in the display area 32a of the liquid crystal display device 32, when a game ball wins the start opening 25 described above, for example, a decorative design for effects including numbers etc. is displayed at the start of the variable symbol display. Fluctuation display is started. Further, when the game ball wins the start opening 25 during the variation display regarding the special symbol, the effect based on the winning of the game ball at the start opening 25 until the decorative design for the effect during the variation display is stopped and displayed. Execution (start) of variable display of decorative symbols for use is suspended. Thereafter, when the decorative design for effect that has been variably displayed is stopped and displayed, the variable display of the decorative symbol for effect that has been put on hold is started. That is, the decorative display variation display and the special design variation display performed in the display area 32a of the liquid crystal display device 32 are synchronized, and the variation start and variation stop are performed at the same timing. .

  In the present embodiment, both the special symbol and the decorative symbol function as identification information, and the special symbol game which is a unit game from the change display of the special symbol to the stop display is executed in synchronization with the special symbol. The game is a “variable display game” in combination with a game in which the unit game is displayed from the change display of the decorative symbols to the stop display. Therefore, in the pachinko gaming machine 10 according to the present embodiment, a variable display game is performed when a game ball wins the start opening 25. A game in which this variable display game is played is called a normal game.

  Further, when the game ball passes through the passing gate 54 (see FIG. 3) provided on the left side of the approximate center of the game area 15, the normal symbol is displayed on the normal symbol display 35 provided on the right side of the special symbol display 33. Two display lamps composed of symbols such as “◯” and “x” shown are variably displayed by alternately turning on and off.

  Further, below the display case 37, normal symbol holding lamps 35a to 35d are provided. The normal symbol holding lamps 35a to 35d are turned on or turned off when the game ball passes through the passing gate 54 during the fluctuation of the above-described normal symbols (in this embodiment, symbols such as “O”, “X”). By turning off the light, the number of times that the fluctuation display of the normal symbol being held can be executed (so-called “the number of balls held in the normal symbol”) is displayed. That is, the normal symbol hold lamps 35a to 35d are turned on sequentially from the left in accordance with the number of executions of the fluctuation display of the held normal symbols, and when the fluctuation is stopped and displayed, the next normal symbol that has been held is held. Is displayed, and the corresponding normal symbol holding lamp is turned off. Note that an upper limit is set for the number of times that the execution of the variable symbol display is suspended. For example, the upper limit is four times (pieces).

When this normal symbol is stopped and displayed as a predetermined symbol, for example, “◯”, the blade members (so-called “normal electric accessories”) 23 provided as variable members on the left and right sides of the start port 25 are released from the closed state. The game ball easily enters the start opening 25 by changing to the state. Further, when a predetermined time has elapsed after the blade member 23 is opened, the blade member 23 is closed to make it difficult for a game ball to enter the start port 25.
As described above, a game in which the normal symbol is displayed in a variable manner and then stopped and the open / closed state of the blade member 23 differs depending on the result is referred to as a “normal symbol game”.

[Game machine operation]
Here, the game of the pachinko gaming machine 10 in this embodiment will be briefly described.
In the present embodiment, the following gaming operation of the pachinko gaming machine 10 is executed under the control of the main CPU 66 in accordance with a program stored in the main ROM 68 of the main control circuit 60.
The games of the pachinko gaming machine 10 are roughly divided into normal games (games that consume game balls while performing lottery lottery, games that are relatively disadvantageous to the player compared to jackpot games) and jackpot games (for the player). It can be divided into so-called games advantageous to the player) that can be expected to acquire a large amount of game balls in a short time.

Further, the jackpot game is drawn by a jackpot lottery process, and a specific numerical symbol displayed on the special symbol display 33 is stopped and displayed, and a 15R probability variation jackpot game (2R probability variation jackpot game) Or three types of jackpot games of 10R normal jackpot games are determined.
The three types of jackpot games (15R probability variation jackpot game, 2R probability variation jackpot game or 10R normal jackpot game) refer to the jackpot lottery table (see FIG. 6), and depending on the normal mode or probability variation mode of the normal game, respectively. The lotteries are drawn with different lottery probabilities.
At this time, when the jackpot game is won, the special symbol that is stopped and displayed on the special symbol display 33 (see FIG. 4) is, for example, a special symbol of “7” is displayed in the case of a 15R probability variable jackpot game. In the case of a probable big hit game, for example, a special symbol of “3” is displayed. In the case of a 10R normal jackpot game, for example, a special symbol of “5” is displayed.

  Further, when one of the three types of jackpot games is won, the display of the liquid crystal display device 32 is performed at the same timing as when the special symbol is stopped and displayed on the special symbol display 33 (see FIG. 4). Also in the area 32a, a special decorative pattern (for example, a set of three numbers) is displayed in the case of a 15R probability variation big hit game, for example, a specific set of decorative numbers such as “777”. In the case of 2R probable big hit games, for example, a set of three decorative symbols of specific numbers such as “333” is displayed. Further, in the case of a 10R normal jackpot game, for example, a decorative pattern of a set of three specific numbers such as “444” is displayed.

  When any of the three types of jackpot games is executed, the upper limit is a predetermined number corresponding to each of the three types of jackpot games (two times for 2R probability variable jackpot games, 15 times for 15R probability variable jackpot games, 10R Normally, 10 times in the big hit game), the shutter 40 (see FIG. 3) attached to the big prize opening 39 repeats opening for a predetermined time (for example, 30 seconds), so that the game balls launched into the game area 15 It becomes easy to win the big prize opening 39, and the player can acquire a large number of prize balls in a short time. Acquiring such a jackpot game (winning the jackpot game) is the greatest goal of general players, and can be said to be the best part of a pachinko game.

  Further, in the present embodiment, during execution of the jackpot game, the number of rounds from the first round number to the last round game when the round game is continued (maximum number of continuous rounds) is 15 rounds, 10 rounds, Although the number of rounds is two, the maximum number of consecutive rounds of the jackpot game is not limited. For example, the maximum number of continuous rounds may be set to any number from “1” to “15”.

On the other hand, the normal game in the present embodiment is executed under three types of game modes: a normal mode (normally low probability game state), a probability variation mode (special high probability game state), and a short time mode (special game mode).
Here, the mode transition of each of the three types of normal games (the normal mode, the probability variation mode, and the time reduction mode) and their characteristics will be briefly described below.

The normal mode is a basic mode in the pachinko gaming machine 10, and when the power is turned on to the pachinko gaming machine 10, the game is started from this normal mode.
In this normal mode, the jackpot lottery probability is set to be lower than the jackpot lottery probability in the probability variation mode.

The probability variation mode is a special high-probability gaming state in which a transition is made after the jackpot game ends when a 15R probability variation jackpot game or a 2R probability variation jackpot is won among the three types of jackpot games in normal games. The jackpot lottery probability in the probability variation mode is set to be higher than the jackpot lottery probability in the normal mode.
Specifically, in this embodiment, the jackpot lottery probability in the normal mode is “1/300”, whereas the jackpot lottery probability in the probability variation mode is “1/30”, which is 10 times the lottery. The probability is set (see FIG. 6, jackpot lottery table).
In other words, in the probability variation mode, a jackpot game is generated 10 times more frequently than in the normal mode, which is an advantageous gaming state for the player. In particular, the 15R probability variation jackpot game has a maximum of 15 round games. This is the most advantageous game because it is continued.
On the other hand, the 2R probability variation jackpot has only two round games, and the duration of the jackpot game is the shortest game among the jackpot games, so when the normal game after the winning game is in the probability variation mode However, it cannot be said that the player is a favorable jackpot game as compared to the 15R probability variable jackpot game.

Finally, the time-saving mode (special game mode) is a game mode that is set after the jackpot game is ended, regardless of which of the three types of jackpot games is won.
In this normal game, the time-saving mode means that the variation time from the start of the special symbol and the normal symbol to the time when the special symbol and the normal symbol are stopped is set to be shorter than that of the normal mode. In the case of “winning” (that is, when the display lamp is stopped and displayed as “O” in the above-described normal symbol display 35 (see FIG. 4)), the opening time of the blade member 23 attached to the start port 25 is It is set longer than the normal mode. Such control may be referred to as “electric chew support” in the present embodiment.
As described above, when “electric chew support” is executed, it becomes easy to win a game ball at the start opening 25, so that the number of lottery wins per unit time is remarkably increased as compared to the normal mode, and to the start opening 25. Since the payout of the winning ball for the winning of the game is also increased, there is little loss of the gaming ball (so-called “ball holding” is in a good state), which can be said to be an advantageous state for the player.

In this short-time mode, the duration is determined corresponding to the three types of jackpot games. When the jackpot game is a 10R normal jackpot game, after the jackpot game ends, the number of times the special symbol fluctuates (for example, 50 times or 100 times) is set as the duration.
On the other hand, when the jackpot game is a 15R probability change jackpot game or a 2R probability change jackpot game, the duration of the special symbol that can be expected to win the next jackpot game substantially after the jackpot game ends (for example, 10,000 times). ).

  As described above, in the present embodiment, the normal game is performed under the four game modes of “normal mode”, “probability change mode”, “normal mode + time reduction mode”, and “probability change mode + time reduction mode”. That is, the gaming state is appropriately changed according to the change of the gaming state of the pachinko gaming machine 10.

[Electric configuration of launch control circuit]
Here, the launch control circuit 127 of the pachinko gaming machine 10 in the present embodiment will be described with reference to FIG. FIG. 9 is a block diagram showing the launch control circuit 127 in the present embodiment.

As shown in the figure, the launch control circuit 127 in this embodiment includes a launch CPU 300, a launch ROM 301, and a launch RAM 302, which are control means.
The launch CPU 300 is connected to a launch ROM 301, a launch RAM 302, and the like, and executes various processes such as launch control of a game ball and current supply processing to the electromagnet 27 in accordance with a program stored in the launch ROM 301. It has a function.

  The launch RAM 302 has a function of storing various flags and variable values as a temporary storage area of the launch CPU 300.

In addition, the launch control circuit 127 includes a launch device control circuit 303 that controls the launch intensity of the game ball according to the amount of rotation by which the player turns the launch handle 26.
The launcher control circuit 303 performs control to adjust the launch intensity by changing the power supplied to the launcher 130 having a launch solenoid or the like based on an instruction from the launch CPU 300.

Furthermore, the launch control circuit 127 includes an electromagnet control circuit 304 that controls the current supplied to the electromagnet 27 in accordance with the launch intensity of the game ball.
The electromagnet control circuit 304 performs control to stabilize the game ball ejected into the game area 15 at a certain ejection position by changing the current supplied to the electromagnet 27 based on an instruction from the launch CPU 300. .

In addition, a rotation operation detection circuit 305 that detects a rotation operation of the emission handle 26 is connected to the emission control circuit 127.
The rotation operation detection circuit 305 is connected to the launch handle 26, and when a rotation operation of the launch handle 26 by the player is detected, a detection signal corresponding to the turn operation is supplied to the launch CPU 300.
The rotation operation detection circuit 305 detects not only a detection signal of the rotation operation of the firing handle 26 but also a signal of a touch sensor (not shown) that detects that the player has touched the firing handle 26. Supply to launch CPU 300.

The launch control circuit 127 is connected to magnetic sensors 28a and 28b.
As described above, the magnetic sensors 28a and 28b detect the wobbling in the depth direction when the game ball is ejected from the game ball guiding path 30c to the game area 15, and the vicinity of the magnetic sensors 28a and 28b. Is detected, the detection signal is supplied to the launch CPU 300.

[Game Ball Launch Control Processing]
Here, the launch control of the game ball and the current supply control process to the electromagnet 27 executed in the launch control circuit 127 will be described with reference to FIG.
FIG. 10 is a flowchart showing processing of game ball launch control and current supply control to the electromagnet 27 executed by the launch control circuit 127.

  As shown in FIG. 10, the firing control circuit 127 performs a firing main process. This launch main process is a process that is started when the pachinko gaming machine 10 is powered on.

First, in step S10, the firing CPU 300 determines whether or not there is a touch sensor detection signal when the player operates the firing handle 26. If there is no detection signal, the process proceeds to step S13. On the other hand, if there is a detection signal, the process proceeds to step S11.
In step S11, the firing CPU 300 determines whether or not the player has turned the firing handle 26. If the turning operation has not been performed, the firing CPU 300 moves the process to step S13. If the firing handle 26 has been rotated, the process proceeds to step S12.

In step S <b> 12, the launch CPU 300 instructs the launcher control circuit 303 to determine the launch intensity according to the turning operation of the launch handle 26 by the player detected by the turning operation detection circuit 305 (see FIG. 9).
Thereby, the launching device control circuit 303 supplies power corresponding to the instructed launching intensity to a launching solenoid (not shown) of the launching device 130, so that the player can turn the launching handle 26. A game ball is launched into the game area 15 with a launch intensity corresponding to the amount. When this process ends, the process moves to a step S14.

In step S <b> 13, the launch CPU 300 instructs the launcher control circuit 303 to stop launching the game ball, and instructs the electromagnet control circuit 304 to stop supplying current to the electromagnet 27.
That is, when the player does not touch and rotate the launch handle 26, the game ball is not fired, and at the same time, the current supply to the electromagnet 27 is stopped.
When this process ends, the process moves to a step S10.

  In step S14, the firing CPU 300 determines whether or not the passing trajectory of the game ball guiding path 30c of the gaming ball described above is in a fixed position. If it is in the fixed position, the firing CPU 300 notifies the electromagnet control circuit 304 in step S15. On the other hand, an instruction to supply a reference current corresponding to the emission intensity to the electromagnet 27 is given, and the process proceeds to step S10. On the other hand, if it is not the fixed position, in step S16, the firing CPU 300 instructs the electromagnet control circuit 304 to correct the reference current according to the firing intensity and supply it to the electromagnet 27, and the process proceeds to step S10. Transfer.

  Here, with reference to FIG. 8 and FIG. 11, the passing position of the game ball of the game ball guiding path 30c, the reference current value supplied to the electromagnet 27, and the correction value in the present embodiment will be described. FIG. 8 is a diagram showing a change in the passing position of the game ball on the game ball guiding path 30c. FIG. 11 is a diagram showing a reference current value and a correction value supplied to the electromagnet 27 in accordance with the firing intensity.

As shown in FIG. 8A, when a reference current corresponding to the firing strength is supplied to the electromagnet 27, the game ball launched into the game ball guiding path 30 c is played by the electromagnetic force of the electromagnet 27. It is injected into the game area 15 at a fixed position attracted to the side (that is, the game ball is detected by the magnetic sensor 28).
In the present embodiment, the current value supplied to the electromagnet 27 according to the launch intensity is stored in advance in the launch ROM, and as shown by the solid line in FIG. The reference current value supplied to the electromagnet 27 also increases as the player turns the firing handle 26).
Specifically, as shown in FIG. 11, when the firing intensity is “V1”, the reference current value “A1” is supplied to the electromagnet 27.

However, for example, due to factors such as a change in the launch intensity and a change in the weight of the game ball, the passing trajectory of the game ball launched into the game ball guiding path 30c is not played by the electromagnetic force of the electromagnet 27 supplied with the reference current value. There is a case where it is injected into the game area 15 in a state where it cannot be sucked to the board 14 side.
Therefore, as shown in FIG. 8B, when the game ball is detected by the magnetic sensor 28a instead of the magnetic sensor 28b at the fixed position at the game ball injection position in the game ball guiding path 30c, The reference current value corresponding to the firing intensity supplied to the electromagnet 27 is corrected and supplied on the assumption that the fluctuation in the depth direction occurs.

As a result, the electromagnetic force of the electromagnet 27 is increased and the game ball 14 is attracted more strongly to the game board 14 side, so that the game is performed at a fixed position where the magnetic sensor 28b detects the game ball as shown in FIG. A ball can be injected into the game area 15.
That is, when the injection position of the game ball from the game ball guiding path 30c to the game area 15 is not a fixed position as shown in FIG. 8B, the correction is made with respect to the reference current value shown by the solid line in FIG. By adding the value “α”, the “reference value + correction value” indicated by the dotted line is supplied to the electromagnet 27.
Specifically, as shown in FIG. 11, when the firing intensity is “V1”, the correction value “α” is added to the reference current value “A1”, and the current value “A1 + α” becomes the electromagnet 27. Will be supplied.

The pachinko gaming machine 10 according to the present embodiment controls the depth direction of the game ball in the game ball guide path 30c when the game ball is launched into the game area 15 by the control of the launch control circuit 127 (see FIG. 9) described above. In order to prevent the wobbling in the electromagnet 27, the electromagnet 27 is controlled by supplying the electromagnet 27 with current corresponding to the firing strength and the injection position of the game ball from the game ball guiding path 30 c to the game area 15. Due to the generated electromagnetic force, the game ball can be ejected to the game area 15 at a fixed position attracted to the game board 14 side.
Thereby, when the player aims the game ball at a desired position in the game area 15 and rotates the launch handle 26, the play position in the game area 15 is prevented from drifting in the depth direction. Therefore, stable rolling and flowing down of the game ball in the game area 15 can be realized.

The following gaming machines are realized by the above embodiment.
That is, the launching means (for example, launch handle 26) for launching a game ball by the player's operation, the game area (for example, the game area 15) in which the game ball rolls, and the game ball launched by the launch means are A game board (e.g., game board 14) having launch rails (e.g., launch rail 30, outer rail 30a, inner rail 30b, and game ball guide path 30c) that lead to the game area, and magnetic along the launch rail A gaming machine (pachinko gaming machine 10) provided with a member (for example, an electromagnet 27) and capable of attracting the gaming ball to the gaming board side.

  A gaming machine (pachinko gaming machine 10) in which the magnetic member (eg, electromagnet 27) is embedded in the gaming board (eg, gaming board 14).

  The magnetic member (e.g., electromagnet 27) is an electromagnet, and is fired by electromagnetic force control means (e.g., launch control circuit 127) that performs control to change the electromagnetic force of the electromagnet, and by the launch means (e.g., launch handle 26). And detecting means (for example, magnetic sensors 28a, 28a, 28a, 28c) that detect the position in the depth direction of the game ball that travels along the launch rail (for example, the launch rail 30, the outer rail 30a, the inner rail 30b, and the game ball guiding path 30c) 28b), wherein the electromagnetic force control means changes the electromagnetic force of the magnetic member based on the detection position of the game ball of the detection means (pachinko game machine 10).

  Moreover, as a configuration of the detecting means for detecting the position in the depth direction of the game ball, in the present embodiment, the configuration is such that the game ball can be detected in a non-contact manner using the magnetic sensors 28a and 28b. For example, an optical sensor or the like may be used as the non-contact detection means.
