Description

  The present invention relates to a gaming machine such as a pachinko gaming machine.

  Conventionally, for example, in a pachinko gaming machine, which is one of the gaming machines, when a pachinko ball wins at the start winning opening, the symbol displayed on the image display device starts to fluctuate and is stopped after a certain period of time. When certain conditions such as being in a specific combination are met, the big winning device provided in the game area of the game board is opened, and the player can acquire many pachinko balls.

  Here, the opening / closing door is installed in the opening portion of the grand prize winning device. When the opening / closing door is opened, the game ball can enter, while when the opening / closing door is closed, the game ball enters. Becomes difficult. In the grand prize winning device, basically, once the open / close door is opened, a predetermined number of game balls (for example, eight) are detected until a predetermined number of times (for example, eight) are entered, or after a predetermined time has elapsed. The open / close door is in an open state until it has elapsed, and then the open / close door is closed. Then, the above operation is set as an operation for one round, and the opening and closing operations are repeatedly performed by the number corresponding to the number of jackpot rounds. In addition to the large winning device, other winning devices such as a start winning port and a V winning port have a similar opening / closing structure with an open / close door.

  Further, in an open / close type winning device using an open / close door such as the above-described large winning device, the detection of a game ball that has entered the winning device is performed by a detection switch provided in the winning device. This detection switch is installed, for example, in a passing hole formed on a rolling surface on which a game ball rolls in the winning device, and detects that the gaming ball has won the winning device when the gaming ball passes through the passing hole. It has become. Conventionally, as shown in FIG. 8, the passage hole 101 is basically arranged at the corner of the big winning device 102, so that the game ball 103 passes through the through hole 101 after entering the big winning device 102. There is a slight time lag between rolling on the rolling surface 104 until the game ball 103 enters the big winning device 102 until it is detected that the game ball 103 has won. As a result, there are cases where more game balls enter the number than the predetermined number for one round (hereinafter referred to as over winning). In particular, when the large winning device is made large, there is a problem that over winnings frequently occur.

  Therefore, for example, Japanese Patent Application Laid-Open No. 2005-192893 discloses a detection switch that forms three guide grooves on the open / close door of the grand prize winning device and detects game balls at three positions guided by the respective guide grooves. There has been proposed a technique for preventing over-winning by providing each of the arranged through holes.

JP 2005-192893 A

  However, in the technique of Patent Document 1, it is necessary to arrange a plurality of passage holes and detection switches with respect to one big winning device. As a result, the structure of the gaming machine is complicated, and there is a possibility that the gaming machine will increase in failure. In addition, providing a plurality of detection switches complicates the control processing related to the game. Furthermore, in recent years, there are many gaming machines in which a plurality of prize winning devices are provided for one game board, and it is also desired that the prize winning devices have a simple structure as much as possible to reduce the arrangement space. Further, with respect to winning devices other than the big winning device, there is a possibility that the same problem may occur in the open / close type winning device using the open / close door.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine that saves space in the winning device and prevents the winning device from being over won.

In order to achieve the above object, the gaming machine according to claim 1 is provided in the gaming area of the gaming board and is released when a predetermined gaming state is reached, and the number of gaming balls according to the number of gaming balls entered. The winning device is provided at an opening of the winning device, the open state in which a game ball can enter the winning device, and the gaming ball is difficult to enter in the winning device. An opening / closing door that switches between a closed state, a rolling surface on which a game ball that has entered the winning device via the opening / closing door rolls, and an upper side of the rolling surface inside the winning device. In addition, an internal space having a triangular cross section is formed together with the inner side surface of the open / close door and the rolling surface in a closed state by inclining downward from the opening side to the back side and connecting to the rolling surface. An inclined surface and within the rolling surface and adjacent to the opening A passing hole formed when the gaming ball rolling on the rolling surface passes, and a winning detection means for detecting the gaming ball passing through the passing hole as a winning game ball in the winning device If, have a, the passage hole, the game ball rolling on the said door is characterized in that it is in direct ball entrance positions.
The “winning device” includes other winning devices as long as it is an open / close-type winning device using an open / close door in addition to the large winning device.

According to the first aspect of the present invention, since the game ball that has entered the winning device is quickly guided to the winning detection means by coming into contact with the inclined surface, the game ball has entered the winning device. It becomes possible to reduce the time lag until it is detected by the winning detection means. As a result, it is possible to prevent over winning in the winning device. In addition, since the winning detection means is provided at a position adjacent to the opening of the winning device, it is possible to further reduce the time lag from when the game ball enters the winning device until it is detected by the winning detection means. .

  The jackpot random number counter is used for determining whether or not the jackpot is won for winning in the first start winning opening 42 or the second starting winning opening 46, and has a jackpot random number value from '0' to '629'. The jackpot random number value (numerical data) in the jackpot random number counter starts from “0” when the gaming machine is turned on, and is incremented by 1 every main random number update process described later. The above addition is repeated again. The jackpot random number value is acquired because the winning to the first start winning opening 42 or the second starting winning opening 46 is detected by the start winning opening detecting switch. If the acquired jackpot random number value (acquired numerical data) is compared with a preset hit value, it becomes a jackpot (win), and if it does not match, it is lost.

  In the present embodiment, in the low probability state, two of “3” and “397” are set as the winning value, and if the acquired jackpot random number value matches either of these, the result of the determination is a jackpot (that is, The jackpot probability in the low probability state is 2/630). On the other hand, at the time of probability change, “3”, “33”, “53”, “59”, “113”, “173”, “227”, “281”, “337”, “397”, “449”, “ Twelve of 503 ′ are set as winning values, and if the acquired jackpot random number value matches any of these, the result of the determination is a jackpot (that is, the jackpot probability at the time of probability change is 12/630). In this way, the winning / failing determination means (the CPU of the main control board 200) performs the lottery by acquiring random numbers due to the establishment of the determination condition of winning the game ball to the first start winning opening 42 or the second starting winning opening 46. Judge whether it is a big hit or not.

  In the gaming machine 1 according to the present embodiment, the internal lottery (the lottery with the jackpot symbol random number counter. Details will be described later), the game will be a normal jackpot that is a game in a low probability state even after the jackpot, and a game in a probable state after the jackpot. It is distributed to a probable jackpot. In the case of a normal jackpot, among the special symbols (“0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11”), even symbols (“0, 2, 4, 6, 8”) , 10 '') are displayed on the display unit 11 in a stopped manner. In the case of a probable big hit, out of special symbols (“0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11”), odd symbols (“1, 3, 5, 7, 9”) , 11 '') are arranged on the display unit 11 in a stopped manner.

  In the present embodiment, after the normal jackpot game is over, the time is reduced until the determination of success / failure is made a maximum of 100 times. After the determination is made 100 times, the time reduction is canceled and the normal state is maintained until the next jackpot. In addition, after the probable jackpot game is over, the probabilistic state (high probability state) and the short time state are maintained until the next jackpot. In the game in the short time state, as will be described in detail later, the lottery probability per normal symbol is improved from 1/300 to 299/300, and the opening time of the opening / closing member 46A is increased from 1 second to 2 seconds. The number of times of expansion increases from 1 to 3 times. Therefore, in the time-short state, it becomes easy to win the second start winning opening 46, and it is possible to play a game in anticipation of the next jackpot while suppressing the reduction of the holding ball.

  The reach random number counter is used for determining whether or not a reach state is reached when the result of the determination is wrong, and includes a reach random number value from ‘0’ to ‘126’. The reach state in the present embodiment is other than the special symbol (for example, the middle special symbol) that is stopped and displayed last among the left special symbol, the middle special symbol, and the right special symbol that are displayed in the display unit 11 with the variable stop. Special symbols (for example, the left special symbol and the right special symbol) are the same (except for the final stop symbol, it is the same as the special bonus combination except for the final stop symbol). Included state).

  This reach random number value starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 for each main random number update process to be described later. Repeat addition. The reach random number value is acquired due to the fact that the winning to the first starting winning port 42 or the second starting winning port 46 is detected by the starting winning port detection switch. Whether the reach is present or not is determined by comparing the numerical value with a predetermined reach establishment value. In this embodiment, the reach establishment numerical values are “5”, “17”, “28”, “40”, “51”, “63”, “74”, “86”, “97”, “109”, “ 120 '. In the present embodiment, the reach randomness value based on the jackpot random number value is always reach, so the reach random number value is not used for the presence / absence of reach.

  The variation pattern random number counter is used when selecting a special symbol (identification symbol) or a variation pattern of an effect mode to be described later from the variation pattern table, and includes variation pattern random numbers from “0” to “198”. . The random number value of the fluctuation pattern starts from “0” when the power of the gaming machine 1 is turned on, and is incremented by 1 for each main random number update process described later. When the numerical value reaches “198”, it is set to “0”. And repeat the above addition. The fluctuation pattern random number value is acquired due to the fact that the winning to the first start winning opening 42 or the second starting winning opening 46 is detected by the start winning opening detecting switch.

  The variation pattern table includes a plurality of variation patterns to be displayed on the display unit 11 and is stored in the ROM of the main control board 200. There are six types of variation pattern tables: a low probability state hit table, a low probability state reach loss table, a low probability state lose table, a probability variation state hit table, a probability variation state reach loss table, and a probability variation state loss table. Each variation pattern table is provided with a plurality of variation patterns, and each variation pattern is assigned a variation pattern random value.

  The selection of the variation pattern from the variation pattern table is based on whether the current low probability state or the probability variation state, whether the determination result by the determination unit is a hit or not, whether there is a reach, or not. A corresponding table is selected from among them, and one variation pattern is selected from the selected table based on the variation pattern random value. The selected variation pattern is output to the sub-control board 205 as a variation command.

  Each variation pattern is set with a variation time for variably displaying a special symbol (identification symbol) and an effect mode described later in a predetermined pattern, and the variation time is set when the variation display of the special symbol on the display unit 11 is started. The

  For each of the numerical data such as the jackpot random number value, jackpot symbol random number value, reach random number value, variation pattern random number value, etc., a maximum of four each, and the special symbol variation pending number in the corresponding area in the RAM of the main control board 200 Stored in correspondence and used sequentially.

  Next, the game of the gaming machine 1 will be briefly described. In the gaming machine 1, when the game balls launched by the launching device 64 toward the game area 6 win the various winning holes, a predetermined number of gaming balls corresponding to the winning holes become the upper balls receiving tray 36 as the winning balls. To be paid out. When the game ball passes through the normal symbol change start gate 45, the normal symbol starts to change in the normal symbol display device 50, and stops after a predetermined time change. At that time, in the case of a normal symbol, the opening / closing member 46A of the second start winning opening 46 is changed from a closed state where it is difficult to win a prize to an open state where it is easy to win a prize by a solenoid for starting prize opening on the back, and the game ball wins. It becomes easy. When a game ball enters the first start winning opening 42 and the second start winning opening 46 and is detected by the start winning opening detecting switch (wins), a predetermined number of game balls are paid out as a winning ball.

  Further, numerical data such as a jackpot random number value, a reach random number value, a variation pattern random number value, etc. are acquired due to the winning of the game ball in the first start winning opening 42 or the second starting winning opening 46. The acquired random number value (numerical data) is stored in the RAM (holding storage means) of the main control board 200, and the special symbol variation, the determination of the success / failure and the display of the determination result are suspended, and the jackpot random value (numerical value) Data), that is, the number of winnings to the first starting winning port 42 and the second starting winning port 46 is stored in the RAM (holding storage means) of the main control board 200 as a special symbol variation holding ball number.

  When there is storage (holding) of random numbers (numerical data) in the RAM (holding storage means) of the main control board 200, determination of whether or not to win a jackpot, determination of reach or not, etc. are performed before starting the special symbol variation display. At the same time, a variation pattern is selected from the variation pattern table based on the variation pattern determination random value or the like, and the variation display of the special symbol is started on the display unit 11 based on the selected variation pattern. The special symbol variation display starts in accordance with the acquisition order of the random number values (numerical data) stored in the RAM (holding storage means), that is, the order in which the first start winning opening 42 and the second starting winning opening 46 are won. Executed. Further, the stored random number value (numerical data) is erased from the RAM (holding storage means) based on whether or not the validity determination is performed by the validity determination means.

  After a lapse of a predetermined time (variation time set for each variation pattern) from the start of the variation display of the special symbol, the special symbol stops varying and the jackpot determination result is displayed on the display unit 11.

  When the determination result is a big hit, the special symbol is stopped and displayed on the display unit 11 at a scale such as “5, 5, 5”. When the jackpot is reached, a special game (a jackpot game) is executed. When a special gaming state (a big hit gaming state) is reached, the big winning solenoid 60 is actuated to open the opening / closing door 49, so that the gaming ball can enter the big winning device 43 from a closed state where it is difficult to enter the gaming ball. Switch to state. When a winning of a game ball to the big winning device 43 is detected by a winning detection switch 61 arranged in the big winning device 43, a predetermined number of gaming balls are paid out as a winning ball. The grand prize winning device 43 opens the door 49 until the predetermined number of game balls are detected by the winning detection switch 61 after the open / close door 49 is opened, or until a predetermined time elapses. Thereafter, the operation of switching the open / close door 49 from the open state to the closed state is repeated a predetermined round (predetermined number of times).

  For example, the number of jackpot rounds is set to 15 rounds (15R), and in the case of a jackpot, the opening and closing of the big winning device 43 is repeated 15 rounds. In addition, while the jackpot game is being performed (that is, while the big winning device 43 is being opened and closed), an effect suggesting that the jackpot is being won (hereinafter referred to as a jackpot round effect) is performed. In the jackpot round effect, special images, music, etc. that are not output in the normal state are output, which suggests that the player is in a jackpot.

  If the jackpot is a normal jackpot (an even number of special symbols), after the jackpot game is over, the player is put in a time-saving state until the determination of success / failure is made a maximum of 100 times. If the jackpot is a promising jackpot (an odd number of special symbols), after the jackpot game is over, the player is placed in a probabilistic state (high probability state) and a short time state until the next jackpot.

  Next, the configuration of the big prize device 43 installed in the gaming machine 1 according to the present embodiment will be described in more detail below. FIG. 4 is an enlarged front view showing the vicinity of the big prize device 43 installed in the gaming machine 1 when the big prize device 43 is in an open state. FIG. 5 is an enlarged front view showing the vicinity of the big winning device 43 installed in the gaming machine 1 when the big winning device 43 is in a closed state.

  As shown in FIGS. 4 and 5, the grand prize winning device 43 has a rectangular shape for entering a game ball 70 rolling on the game board 2 on the same plane as the game board 2 and in parallel with the game board 2. An opening 71 is provided. The opening 71 has an open / close door 49 that switches between an open state in which the game ball 70 can enter the big prize device 43 and a closed state in which the game ball 70 is difficult to enter in the big prize device 43. .

  Here, the open / close door 49 has a rectangular flat plate shape, and is supported so as to be rotatable with respect to the big prize device 43 with the lower end as a rotation axis. And an open state and a closed state are switched by rotating to the glass frame side (player side) or the game board 2 side (back side) centering on a rotating shaft.

  Further, inside the grand prize winning device 43, the rolling surface 72 on which the game ball 70 that has entered the grand prize winning device 43 rolls, that is, the bottom face inside the big prize winning device 43, A passing hole 73 through which the game ball 70 entering the ball passes is provided. Here, FIG. 6 is a cross-sectional view of the large winning device 43 cut from the side, particularly near the passage hole 73.

  As shown in FIG. 6, the passage hole 73 is a passage formed vertically downward from the rolling surface 72 and has an inner diameter that is slightly larger than the diameter of the game ball 70. Note that the size of the passage hole 73 only needs to be larger than the diameter of the game ball 70, but if it is too large, it is difficult to accurately count the game ball 70 by the winning detection switch 61 described later. Make it as large as possible. In the present embodiment, as shown in FIG. 4, the passage hole 73 is formed in the right corner of the rolling surface 72, but it may be formed in the left corner or near the center. Further, the passage hole 73 is formed at a position adjacent to the opening 71 as much as possible in order to reduce a time lag from when the game ball 70 enters the big winning device 43 until it is detected by the winning detection switch 61. Is desirable.

  As shown in FIG. 6, a winning detection switch 61 is provided near the entrance of the passage hole 73 as means for detecting the game ball 70 that has passed through the passage hole 73. The winning detection switch 61 is not necessarily provided in the vicinity of the entrance of the passage hole 73. However, in order to reduce the time lag from when the game ball 70 enters the large winning device 43 until it is detected by the winning detection switch 61. In addition, it is desirable to arrange it as close to the entrance of the passage hole 73 as possible. The winning detection switch 61 is composed of, for example, an optical sensor or a contact type detection switch, and detects the gaming ball 70 passing through the passage hole 73 as the gaming ball 70 winning the big winning device 43.

  Similarly, inside the big prize winning device 43 and above the passage hole 73, there is an inclined surface 74 inclined downward from the opening 71 side to the passage hole 73 side. The inclined surface 74 also corresponds to the ceiling inside the prize winning device 43. In addition, the inclination angle θ of the inclined surface 74 is set to an angle that is most likely to face vertically downward (that is, the direction of the passage hole 73) when the game ball 70 that has entered from the opening 71 comes into contact. Further, as shown in FIG. 6, the position and angle of the inclined surface 74 are designed so that the distance W between the openable door 49 and the inclined surface 74 satisfies the condition that the distance is equal to or larger than the diameter of the game ball 70. . For example, the inclination angle θ of the inclined surface 74 is 60 degrees.

  According to the grand prize winning device 43 having the above configuration, as shown in FIG. 7, a game ball 70 that rolls in the game area 6 of the game board 2 enters the big prize winning device 43 from the open / close door 49 in the open state. When the ball is formed, first, the game ball 70 rolls on the upper surface of the open / close door 49 and comes into contact with the inclined surface 74 at the back of the big winning device 43. And the advancing direction of the game ball 70 is changed by the inclined surface 74, and becomes the vertically downward direction, that is, the direction of the passage hole 73. Thereafter, the game ball 70 whose traveling direction has been changed enters the passage hole 73 and is detected by the winning detection switch 61. That is, in this embodiment, by forming the inclined surface 74, the time until the game ball that has entered the big winning device 43 enters the passage hole 73 (that is, the game ball that has entered the big winning device 43). The time during which the rolling surface 72 rolls until the ball 70 enters the passage hole 73 can be made extremely short compared to the conventional case. Therefore, it is possible to reduce the time lag from when the game ball 70 enters the big winning device 43 until it is detected by the winning detection switch 61, and it is possible to prevent over-winning in the big winning device 43. It becomes.

  In addition, this invention is not limited to the said embodiment, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention. For example, the following may be used.
