Description

  The present invention relates to a gaming machine such as a pachinko machine that plays a game so that a launched ball is awarded to a winning opening arranged on a game board.

  In this type of gaming machine, a player plays a game with the expectation that the ball that has been launched will win the target winning opening. For this reason, the player plays the game while paying attention to the situation where the launched ball collides with a nail or the like and flows down the surface of the game board, and there is a tendency for eye fatigue to increase as the game takes a long time. In addition, it has been difficult for beginners to accurately determine what route the ball is flowing down.

  Therefore, a game machine has been proposed in which a nail and an obstacle are provided with a sensor for detecting the collision of a ball and a light emitting unit so that the head of the nail where the ball collides and the obstacle with which the ball collides are emitted. (For example, refer to Patent Document 1).

JP 2002-282449 A

  In the above technique, since the nail or the obstacle that the ball collides with is emitted, it is possible to check the trajectory of the nail or the ball that has collided with the ball depending on the light. However, since the spot where the ball collides only emits light at the same time as the movement of the ball, there is no difference in the task of chasing the complicated movement in real time even if there is a difference between chasing the ball itself or chasing the light emitting spot. For this reason, it has not been possible to sufficiently reduce the burden on the player who watches the behavior of the ball.

  An object of the present invention is to solve the above-mentioned problems, and a gaming machine that can reduce the burden on a player who watches the behavior of a ball and can reduce eye fatigue even in a long-time game. It is intended to provide.

The invention according to claim 1 is a gaming machine that plays a game so that the launched ball is awarded to a winning opening (25, 27, etc.) arranged on the game board.
A ball detection sensor (40, 22a to 22c, etc.) disposed on the path of the ball toward the winning opening (25, 27, etc.);
Display means (60, 370, 380) capable of displaying a plurality of expectation levels ;
The number of spheres detected by the sphere detection sensor (40, 22a to 22c, etc.) is counted every unit time. When the number is more than a predetermined number, the display is performed except when the level is already at the highest expectation level. means to change the display of one stage high expectations level Ri by current of (60,370,380), when said number is less than said predetermined number, said unless it is already the lowest expected level a game machine, characterized by a control means for changing the display of one step lower expected level Ri by moment the display means (60,370,380) (170).

According to the above invention, the ball to the winning opening (25, 27, etc.) is based on the detection status of the ball detection sensor (40, 22a-22c, etc.) provided on the path of the ball toward the winning opening (25, 27, etc.). The expected level of entering is displayed. A player can get a sense of expectation for winning a prize without actually following the movement of the ball with his eyes only by looking at this display.

The expected level can be displayed by various methods such as a level meter, the number of lamps lit, a message, the type, scale, and volume of sound effects, or a combination thereof.

  The ball detection sensors (40, 22a to 22c, etc.) may be arranged only at important places that greatly influence the possibility of winning a prize, and various kinds of prizes that may win a prize opening (25, 27, etc.). It may be placed at various points along the road.

According to the gaming machine according to the present invention, since the level of expectation that the ball enters the winning opening is displayed based on the detection state of the ball detection sensor provided on the path of the ball toward the winning opening, the player can actually You can get a sense of expectation for winning without following the movement of the ball. Thereby, the burden on the player who watches the behavior of the ball can be reduced, and the player's eye fatigue can be reduced even in a long-time game.

Also, if the number of detected spheres per unit time is greater than or equal to a predetermined number , the display is changed to an expectation level that is one step higher than the present time , except when the number is already at the highest expectation level. If the number is less than the number, the display will be changed to one level lower than the current expectation level except when the level is already at the lowest level, so the display content will change compared to the display corresponding to the movement of each sphere. It becomes gradual and it is possible to display the high and low possibilities.

  Of these, the main board 100 fulfills the function of controlling the overall operation of the gaming machine 10. The main board 100 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) (not shown) as main parts. The main board 100 has a function of calculating the number of prize balls and outputting the prize ball data representing the number to be paid out to the payout control board 120 when a ball prize detection signal is input from the switch 191 provided at each prize opening. Fulfill.

  In addition, when a winning detection signal is input from the start port 25, a random number value is acquired, and this random value indicates whether the display result of the variable display executed by the variable display device 24 is “win” or “out”. Determine based on. In addition, based on this determination, the type of variable display game effect (variation pattern) and the type of symbol (stop symbol / deterministic symbol) constituting the display result are determined, and these are controlled as display control data for variable display. It performs the function of outputting to the board 110, the lamp control board 130, and the sound control board 140. When the display result of the variable display is a win, the solenoid 192 for operating the special winning opening 26 is controlled to generate a specific gaming state.

  Further, the main board 100 obtains a random number value even when a signal representing the detection of the passage of a sphere is input from the normal symbol operation gate 28, and the display results of the variable display executed by the normal symbol display device 29 are “win” and “ It is determined based on this random number value whether to be “out”. According to this determination result, lighting of the LED of the normal symbol display device 29 is controlled to execute variable display. When the result of the variable display is a win, the movable piece of the start port 25 is temporarily controlled to be in an open state, and a state where the ball is easy to win is generated.

  The display device control board 110 performs a function of executing variable display by the variable display device 24 based on the control data received from the main board 100.

  The payout control board 120 controls the operation of paying out balls based on the winning ball data received from the main board 100 and the operation of paying out lending balls based on instructions from the card unit 10b.

  The lamp control board 130 functions to control lighting of the gaming machine status lamp and decoration lamp based on control data from the main board 100 and lighting instructions.

  The sound control board 140 performs output control of effect sound and sound for production based on the control data sent from the main board 100. In addition, a warning sound or the like for notifying an abnormal state is controlled.

  The launch control board 150 has a function of controlling the launch of a launch motor that launches a ball to the game board 12 based on the operation of the handle 15.

  The power supply board 160 fulfills a function of supplying power of a voltage corresponding to each control board and other electrical components.

  The sensor control board 170 serves as a control unit that controls the display state of the expectation degree display unit 60 in accordance with the detection state of each of the ball detection sensors 40, 51, 22a to 22c, and 23b. FIG. 7 shows the configuration of the sensor control board 170. The sensor control board 170 includes a CPU 171, a clock oscillator 172, a decoder circuit 173, and waveform shaping circuits 174a to 174d. The waveform shaping circuits 174a to 174d are circuits that perform waveform shaping of the ball detection signals input from the ball detection sensors 40, 51, 22a to 22c, and 23b provided on the path of the ball that wins the winning opening.

  Here, the waveform shaping circuit 174a includes the sphere detection sensor 51 in the first detection area A in FIG. 4, and the waveform shaping circuit 174b includes the sphere detection sensor 22a in the second detection area B in the waveform shaping circuit 174c.

  The outputs of the waveform shaping circuits 174a to 174d are input to the CPU 171 via the data bus. The decoder circuit 173 decodes the address signal output from the CPU 171 and generates selection signals for the waveform shaping circuits 174a to 174d. Only the waveform shaping circuit selected by this signal outputs the sphere detection signal after waveform shaping to the data bus. The CPUs 171 are connected to LEDs 61 to 67 constituting the expectation degree display unit 60.

  FIG. 8 shows an example of a display process for displaying the possibility of winning higher as the ball approaches the start opening 25. When a sphere is detected in the first detection area A of FIG. 4 (step S201; Y), the LED 61 (see FIG. 5) having the expectation level 1 is turned on (step S202). At the same time, a timer is started (step S211). This timer is set slightly shorter than the minimum interval between balls. For example, when a maximum of 100 balls are fired per minute, the minimum interval is 600 ms, so the timer is set to 599 ms.

  When a sphere is detected in the second detection region B (step S203; Y), the LED 62 with the expected level 2 is turned on and the LED 61 with the expected level 1 is turned off (step S204). Thereafter, when a sphere is detected in the third detection region C (step S205; Y), the LED 63 with the expectation level 3 is turned on and the LED 62 with the expectation level 2 is turned off (step S206). Further, when a sphere is detected in the fourth detection region D (step S207; Y), the LED 64 with the expectation level 4 is turned on and the LED 63 with the expectation level 3 is turned off (step S208).

  With the above processing, as the possibility of winning increases, the lighting location is displayed to move from an LED with a low expectation level to an LED with a high expectation level. In addition, as the possibility of winning increases, LEDs with high expectation levels may be additionally lit sequentially to increase the number of lighting locations.

  When the previous timer expires during or after execution of the processing from step S202 to step S208 (step S212; Y), all the expected level LEDs 61 to 64 are turned off and the processing is terminated.

  By performing such lighting control, the expected level corresponding to the actual movement of the sphere is displayed.

  FIG. 9 shows an example of display processing for displaying the level of the possibility of winning according to the number of balls detected per unit time. Here, it is assumed that the process proceeds only for detection by the ball detection sensors 54 and 55 in the fourth detection region D. Note that other detection areas may be included in the detection target.

  The counting process of the sphere detected by the sphere detection sensor is started (step S221). At the same time, a timer for measuring unit time is started (step S222). This timer is set to 2 seconds, for example.

  When the timer expires (step S223; Y), it is determined whether the count value at that time is 2 or more (a ball has been detected twice or more) (step S224). When the count value is 2 or more (step S224; Y), it is checked whether or not the LED 64 with the highest expectation level 4 is already lit (step S225).

  If the LED 64 with the expectation level 4 is not lit (step S225; N), an LED with an expectation level that is one step higher than the highest expectation level that is currently lit is additionally lit (step S226). Thereafter, the process returns to step S221 to reset the count value and start counting again. If the LED 64 with the highest expectation level 4 is already lit (step S225; Y), the process returns to step S221 while maintaining the lighting state of the expectation level, resets the count value, and starts counting again. To do.

  If the count value is less than 2 (step S224; N), the LED with the highest expected level that is currently lit is extinguished (step S227). Thereafter, the process returns to step S221 to reset the count value and start counting again.

  As a result of the above processing, if the state where there is a detection twice or more per unit time continues, the expectation level displayed on the expectation level display unit 60 gradually increases, and if the detection continues less than twice per unit time, the expectation gradually increases. The degree level is displayed low.
