[Basic operation of pachinko machines]
When the launch handle 8 is turned and operated in a state where the game balls are stored in the upper plate 6, the game balls are launched toward the game board 4. When the launched game ball wins a start opening 14 or a winning opening (not shown), a predetermined number of game balls are paid out as winning balls. Further, when the game ball passes through the gate (not shown), the normal symbol display device 20 displays the variation of the normal symbol, and when the stop symbol is a predetermined hit symbol, it is provided at the start port 14. The ordinary electric accessory 14a is opened for a predetermined time. When the game ball wins the start opening 14, the special symbol display device 18 and the production symbol display device 19 display the special symbols and the variation of the production symbols related to the special symbols, and these symbols are determined in advance. When the player stops at the hit arrangement, the player becomes a big hit mode in which the player can acquire many game balls.
Hereinafter, various game modes of the pachinko gaming machine 1 that are switched in response to the start or end of a big hit will be described with reference to FIG.

(1) Normal game mode In this mode, a low probability (for example, 1/300) is applied among the two stages of jackpot probabilities in the special symbol lottery. In this mode, the normal symbol lottery cycle is long.
(2) Big hit mode This mode is executed when the special symbol (effect symbol) stops in a predetermined hit arrangement, and the special electric accessory 15a provided in the big prize opening 15 is opened. This releasing operation is repeated over a predetermined number of rounds (for example, 15 rounds), with a predetermined time (for example, 30 seconds) or a predetermined number of winnings (for example, 10 balls) as one round.
(3) Probability variation mode This mode is executed with a predetermined probability (for example, ½) after the jackpot mode ends. That is, the special symbol lottery jackpot includes the normal winning in which the winning probability of the special symbol lottery is low after the opening operation of the special winning lot 15 and the winning probability of the special symbol lottery after the opening operation of the special winning lot 15 is performed. There is a probable hit with a high probability. For example, when the stop symbol at the time of big hit is a specific probability variation symbol, the probability variation probability is obtained. In the probability variation mode, the big hit probability is high (for example, 1/30), the lottery cycle of the normal symbol lottery is short, and the opening time of the normal electric accessory 14a is long, so It is possible to generate a big hit again without reducing it.
(4) Time reduction mode This mode is executed after the normal big hit mode ends. In the time reduction mode, the jackpot probability of the special symbol lottery is low, but since the lottery cycle of the normal symbol lottery is short and the opening time of the ordinary electric accessory 14a is long, the game is hardly reduced. Can continue. However, this mode is terminated when the number of changes in the special symbol reaches a predetermined number (for example, 100 times) after the big hit, and the mode is switched to the normal mode.

[Unused display area]
As shown in FIG. 6, the main control board 23 of the present embodiment is provided with an extra electronic component mounting scheduled portion 42 for mounting electronic components to facilitate diversion to other models and recycling. Yes. Specifically, an extra IC socket for mounting ROM is provided, and in models with a large amount of data, by mounting ROM in the extra IC socket, the models with different data capacities can be used. The same main control board 23 can be used. In the present embodiment, the extra electronic component mounting planned portion 42 is an IC socket and the electronic component mounted on the extra electronic component mounting planned portion 42 is a ROM. The electronic components mounted here are not limited to those described above. For example, the extra electronic component mounting planned portion 42 may be a socket for mounting an electronic component other than the ROM, or may be a mounting hole formed on the printed wiring of the control board.

  As shown in FIGS. 6 and 7, the board case 35 according to the first embodiment of the present invention covers the main control board 23 provided with the extra electronic component mounting portion 42 in a state that is visible from the outside. In this case, the first case 39 is provided with an unused display portion 39g. The unused display portion 39g is positioned above the extra electronic component mounting scheduled portion 42 in a state where the substrate case 35 is closed, and displays that the electronic component mounting planned portion 42 is unused. For example, an uneven character string such as “This IC socket is unused. If an electronic component is mounted, there is a possibility of fraud” is formed on the unused display portion 39g, and there is a character string below it. The fact that the electronic component mounting scheduled part 42 is in an unused state is displayed.

  If the board case 35 is configured in this way, the unused display part 39g indicates that the electronic component mounting scheduled part 42 is unused even if there is an extra electronic component mounting scheduled part 42 on the main control board 23. Because it is clearly displayed, you will not be mistaken for forgetting to attach electronic parts. In addition, the unused display part 39g not only exhibits a good deterrent effect against an illegal act of attaching an illegal part to the extra electronic component mounting part 42, but also discovers if an illegal part is attached. And recognition can be facilitated.

  The unused display portion 39g may be formed separately from the substrate case 35 (for example, formed as an unused display seal) and then attached to the substrate case 35, but is preferably formed simultaneously with the substrate case 35. For example, the unused display portion 39g is formed simultaneously with the substrate case 35 by nesting that is selectively incorporated into a mold for forming the substrate case 35. If it does in this way, compared with the case where the unused display part 39g and the board | substrate case 35 are manufactured separately, if it shape | molds using a nest | insert, the unused display part 39g will be formed. The mold of the substrate case 35 and the mold of the substrate case 35 where the unused display portion 39g is not formed can be shared.
