Description

  The present invention relates to a pachinko gaming machine having an electric decoration function.

  Some pachinko machines have a transparent light emitting plate. The light emitting plate has a plate shape having a front surface and a rear surface, and a substrate box is assembled to the light emitting plate. This substrate box has a hollow shape formed by joining a front cover and a rear cover to each other, and the substrate is fixed in the substrate box. A light source is mounted on this substrate. This light source projects light onto the end face of the light-emitting plate. When the light source emits light, the light-emitting plate emits light when light enters the light-emitting plate from the end face of the light-emitting plate.

[2] The front cover is formed integrally with the front light-emitting plate and has a concave shape with an open rear surface. Reference numeral 44 in FIG. 7 corresponds to the front cover.
[3] The rear light-emitting plate is a transparent plate having a front surface and a rear surface. After this, the light emitting plate emits light when light enters from the end surface, and is arranged so that the front surface faces the rear surface of the front light emitting plate. Reference numeral 52 in FIG. 7 corresponds to a rear light emitting plate, and the rear incident surface 54 in FIG. 7 corresponds to an end face.
[4] The rear cover is integrally formed with the rear light emitting plate. The rear cover has a concave shape with an opening on the front surface, and is disposed behind the front cover. Reference numeral 53 in FIG. 7 corresponds to a rear cover.
[5] The substrate storage chamber is provided between the front cover and the rear cover, and each of the end surface of the front light emitting plate and the end surface of the rear light emitting plate is a part of the wall surface. Reference numeral 63 in FIG. 7 corresponds to a substrate storage chamber.
[6] The substrate is provided in the substrate storage chamber so as not to protrude from the substrate storage chamber , and the LED substrate 66 in FIG. 7 corresponds to the substrate.
[7] The front light source is provided on the substrate and projects light onto the end face of the front light emitting plate. The front LED 67 in FIG. 7 corresponds to a front light source.
[8] The rear light source is provided on the substrate and is used to project light onto the end face of the rear light-emitting plate. This substrate is fixed in the substrate storage chamber so that the front light source faces the end surface of the front light emitting plate and the rear light source faces the end surface of the rear light emitting plate. The rear LED 68 in FIG. 7 corresponds to a rear light source.

  The substrate is fixed in the substrate housing chamber so that the front light source faces the end face of the front light emitting plate and the rear light source faces the end face of the rear light emitting plate. The substrate storage chamber is provided between the front cover and the rear cover. The front cover is integrally formed with the front light emitting plate, and the rear cover is integrally formed with the rear light emitting plate. Therefore, the positional relationship of the front cover with respect to the front light emitting plate and the positional relationship with respect to the rear light emitting plate of the rear cover are stabilized without variation for each product, so that the positional relationship of the front light source with respect to the front light emitting plate and Since each of the positional relationships is also stable, light stably enters the end face of the front light emitting plate and the end face of the rear light emitting plate at a target angle from the target position.

  The main control circuit 35 shown in FIG. 4 is mainly composed of a microcomputer, and has a CPU, a ROM, and a RAM. The main control circuit 35 determines whether or not a start signal is output from the start port sensor 28. When it is determined that the start signal is output from the start port sensor 28, the value of the jackpot counter is determined. Detect update results. The value of the jackpot counter is updated by the main control circuit 35 by a fixed value (1) every time a fixed time (4 msec) elapses. The value of the jackpot counter is based on a predetermined lower limit value (0). After adding up to a predetermined upper limit value (100), it is returned to the lower limit value and added cyclically.

  When the value of the big hit counter is detected, the main control circuit 35 compares the detection result of the big hit counter value with the big hit value (7). The jackpot value (7) is determined in advance within the update range of the jackpot counter value. When the main control circuit 35 determines that the detection result of the jackpot counter value is the same as the jackpot value, the jackpot value is determined. If it is determined that the detection result of the value of the jackpot counter is different from the jackpot value, it is determined that it is out of place. The main control circuit 35 transmits a jackpot command to the display control circuit 36 (see FIG. 4) when it is determined that it is a big hit. Send.

  The display control circuit 36 is mainly composed of a microcomputer, and has a CPU, a ROM, and a RAM. The display control circuit 36 sets the identification symbol to a combination of jackpots when it is determined that a big hit command is transmitted from the main control circuit 35, and when it is determined that a disconnect command is transmitted from the main control circuit 35. Set the identification symbol to a combination of deviations. When the combination of identification symbols is set, the display control circuit 36 starts to display each of the symbol elements in the left column to the symbol elements in the right column in a variable state on the symbol display unit 25. When each of the right row of symbol elements starts to be displayed in a variable state, the variable display of the left row of symbol elements is stopped first, the variable display of the right column of symbol elements is stopped second, and the third Stop variable display of symbol elements in the middle row. The stop display of each of the symbol elements in the left column to the right column is performed so that the identification symbol becomes a combination of outliers when the identification symbol is set to a combination of outliers. If the combination is set, the identification symbol is a jackpot combination.

  The main control circuit 35 plays a big hit game when it is determined that the big hit. This jackpot game refers to an aggregate of multiple (5) jackpot rounds, and the main control circuit 35 performs the first jackpot round after the identification symbol is stopped and displayed in the jackpot combination on the symbol display 25. Start. In each of these multiple big hit rounds, the special prize opening solenoid 33 is switched from the electrical OFF state to the ON state to rotate the door plate 31 from the closed state to the open state. Is allowed to win. In each of these multiple big hit rounds, when the opening time of the special winning opening 29 reaches a predetermined limit time (30.0 sec), or the number of winning game balls with respect to the special winning opening 29 is determined in advance. The process ends when (10) is reached, and the main control circuit 35 measures the number of winnings for the special winning opening 29 of the game ball based on the special winning signal from the special winning opening sensor 30.

The lower end portion of the prize ball case 38 is connected to the payout opening 9 of the inner frame 2, and the game ball dropped from the lower end portion of the prize ball case 38 is paid out as a prize into the upper plate 8 through the payout opening 9.

  The payout control circuit 40 of FIG. 4 is configured mainly with a microcomputer, and the main control circuit 35 transmits a prize ball command 1 to the payout control circuit 40 when a start signal from the start port sensor 28 is detected. When the special winning signal from the special winning opening sensor 30 is detected, the winning ball command 2 is transmitted to the payout control circuit 40. The payout control circuit 40 includes a CPU, a ROM, and a RAM. When it is determined that the prize ball command 1 is transmitted from the main control circuit 35, the payout motor 39 is driven to drive the payout ball case 38 upward from the prize ball case 38. When a predetermined number N1 of game balls are paid out as prizes in the tray 8 and it is determined that a prize ball command 2 is transmitted from the main control circuit 35, the payout motor 39 is driven to drive the upper tray 8 from the prize ball case 38.
