In FIG. 2, the main components of the back mechanism of the pachinko machine 1 are a storage tank (upper tank) 71, a guideway 72, a relay base 73, a ball discharging device 74, a probability setting device 75, a ball pulling cover 76, There are a control circuit board 77, a speaker 78, an emission / emission control circuit board 79, an overflow switch 80, a rotary solenoid 81, a human body detection sensor 82, and a base frame 84 of a back mechanism board. Base frame 84
Is made of synthetic resin, and the mounting portion of the base frame 84 is fixed to a mounting frame 121 integrally formed with the resin front frame 11 of the pachinko machine 1 (the details will be described later with reference to FIG. 3). ). On the base frame 84, various unit components (mechanisms) such as a storage tank 71, a guide path 72, a relay base 73, a ball discharging device 74, and a speaker 7 are provided.
8, a discharge / emission control circuit board 79, an overflow switch 80, and the like are attached (for example, fixed by a one-touch member), and these various unit components and the base frame 84 are collectively referred to as a back mechanism board 90. It is called.

The storage tank 71 stores the balls before they are discharged. The shortage of the number of balls in the storage tank 71 is detected by a replenishment sensor (not shown). Is replenished. The balls in the storage tank 71 are guided by the guide path 72 and discharged by the ball discharge device 74. The guide path 72 is not particularly limited, but is formed in two sections so that a large amount of balls can be discharged in a short time, and in the middle thereof, a ball leveling member 91 for preventing weight of the balls and a standby ball detection A vessel (not shown) is provided. Further, such a two-row configuration is the same for the inside of the ball discharging device 54. The relay base unit 73 relays the input of AC power and the transmission and reception of signals with the hall management device. The probability setting unit 75 changes and sets the winning probability of the electric tulip in the ordinary electric starting port 63, and specifically has the following setting contents.

[Contents of Probability Control] The pachinko machine 1 according to the present embodiment performs a control called a so-called neuro-pachinko ordinary power control. This is because the fluctuating control of the general winning probability is simply performed as follows. (I) Normal Time The winning probability of the normal electric starting port 63 is controlled so that three starting winnings are obtained for 100 shots of balls. Specifically, the winning rate is controlled by using a random probability of 1/3 and a random number of 1/30. (II) High Probability The winning probability of the ordinary electric starting port 63 is controlled to 1/3. Therefore, there is one start winning prize for three shots of the ball, and the player is in an extremely advantageous state and the game becomes interesting.

A. Conditions in which the probability of the winning of the general public fluctuates After the big hit of the center role device 62, the probability setting device 75
It is determined whether or not a high probability is obtained by using one of the six-stage probability values described later set by (1). When the next big hit occurs during the high probability, the probability returns to the normal probability. Note that a normal probability is adopted during the big hit. B. Probability setting values Probability values for which the probability of prize winnings fluctuate to a high probability include the following 6
There are stages. [6] 17/32 [5] 13/32 [4] 10/32 [3] 7/32 [2] 5/32 [1] 3/32

The above-mentioned six-stage fluctuation probability values are calculated by the probability setting unit 7.
According to 5, for example, before the opening of the hall, the attendant changes / sets in advance (that is, one of six steps is set). Since this probability setting is important, for sealing,
A locking device is provided, and the probability is set by a staff member of the hall inserting a predetermined key into the key insertion slot. Therefore, there is no need for the player to easily touch it from outside,
Moreover, the value of the probability cannot be seen from the outside. The ball shift cover 76 closes a central opening that is largely opened at the center of the base frame 84, and this central opening is a space for mounting the center accessory device 62. Therefore, by closing the central opening with the ball pulling cover 76, for example, a ball dropped from the storage tank 71 does not collide with the back side of the game board 13.

The accessory control circuit board 77 performs various controls necessary for the operation of the center accessory device 62 arranged on the game board 13. The loudspeaker 78 informs a sound effect necessary for the game (for example, a sound effect at the time of a big hit or discharge of a ball).
Various sounds are generated in accordance with the number of discharged balls, the prize mode, and the lending of the balls to notify the player. Note that the sound of the speaker 78 can be adjusted by a volume adjustment knob 78a. Emission /
The firing control circuit board 79 performs various controls required for discharging and firing the ball, and a base of the discharging / firing control circuit is housed in a predetermined case. And 4 on the outside of the case
Switches, ie, a reset switch 101, a credit clear switch 102, a firing strength setting switch 1
03 and a touch sensitivity adjustment switch 104 are provided. The reset switch 101 performs a reset process of the microcomputer constituting the discharge / emission control circuit board 79. When the reset switch 101 is pressed by a person in the hall, the microcomputer is initialized. The credit clear switch 102 clears the credit, and when the credit is cleared,
The credit is released and the display of the credit number display 22 changes to [0, 0, 0]. The credit is cleared, for example, at the time of opening a store.

The firing strength setting switch 103 is for setting a reference value of the strength of the firing (such as the distance of the ball) in the firing device. The player operates the above-described firing operation switch 35a based on this reference value. Thereby, the strength of the firing is adjusted during the game. Touch sensitivity adjustment switch 1
04 adjusts the touch sensitivity of the firing operation handle 35.
The switches 103 and 104 can be operated, for example, digitally. When the switch is kept pressed, the corresponding value is sequentially incremented and increased, and when the switch is increased to the maximum value, the value is again increased from the minimum value. Is used. As the launch device, a type using a rotary solenoid 81 is used, and the launch device is digitized. The overflow switch 80 detects that the ball storage tray 32 is full, and the overflow state is notified to the player by the overflow lamp 34 described above.

The human body detection sensor 82 detects a state in which the player is present in front of the pachinko machine 1 (ie, a state in which the player is usually sitting in a chair), for example, by detecting infrared rays emitted from the human body. , Detect the player. The detection output of the human body detection sensor 82 is supplied to the emission / emission control circuit board 79 via the terminal board 111 via the wiring 110. The ejection / firing control circuit board 79 activates the rotary solenoid 81 based on the output from the human body detection sensor 82 only when a player is present in front of the pachinko machine 1 and the player is touching the firing operation handle 35. Then, control is performed to allow the ball to be fired, and otherwise to stop firing the ball.

[Arrangement Structure of Boring Device] Next, the arrangement structure of the ball removing device to which the present invention is applied will be described. FIG. 3 is an enlarged view of the vicinity of the mounting portion of the ball punching device. In FIG. 3, reference numeral 120 denotes a ball-dropping device, and the ball-dropping device 120 is disposed above a base frame 84 made of synthetic resin. That is, the boring device 120 is disposed at a predetermined position on the periphery of the back mechanism panel 90 as shown in FIG. On the other hand, the mounting frame 121 is integrally formed on the back side of the front frame 11 of the pachinko machine 1, as described above, and the mounting portion of the base frame body 84 is fixed to the mounting frame 121.

At the time of boring, the boring pin 195 may be inserted into the pin insertion portion 133 of the boring device 120 from the rear side of the pachinko machine 1 and brought into contact with the leaf switch 132 to perform boring.

As described above, in the present embodiment, the ball removing device 12 is used.
0 is attached to the base frame 84 of the back mechanism panel 90, and its position is near the relay base 73 and on the back side of the pilot lamp mounting base 163. Therefore, since the ball removing device 120 is not directly attached to the metal frame portion as in the conventional case, but is directly attached to the base frame 84, the wiring processing related to the ball removing device 120 before attaching the base frame 84 is performed. Can be performed, the wiring process can be simplified, and the efficiency of the wiring operation can be improved. In addition,
When the base frame body 84 is detached from the mounting frame 121, the troublesome work step of first removing the wiring related to the boring device 120 is not necessary, and the efficiency of the wiring work can be improved from this aspect as well. Further, since the ball dropout pin insertion port 165 is opened in the pilot lamp mounting base 163, the ball dropout pin insertion port 165 can be made inconspicuous, and an effect that the aesthetic appearance is not spoiled can be obtained.

In addition, the ball insertion pin insertion hole 165 has a thickness corresponding to the thickness of the pilot lamp mounting base 163 as compared with the conventional structure.
In this case, since the distance from the to the leaf switch 132 of the ball punching device 120 becomes long and the ball punching pin 195 is not inserted deeper, the switch operation (ON operation) cannot be performed, so that it is difficult to be mischievous. Note that the shapes of the pin insertion portion 133 and the leaf switch 132 of the ball punching device 120 are not limited to the types of the above-described embodiment, and can be appropriately changed depending on the model of the gaming machine. Any shape may be used. Further, the arrangement of the ball punching device of the gaming machine according to the present invention is not limited to the example applied to a partly credit type pachinko machine, but can be applied to all other pachinko machines. Further, the same concept can be applied to a gaming machine using a pachinko ball as a game medium, regardless of the type of the gaming machine, in which a ball punching device is disposed.
