Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view of one embodiment of a credit-type pachinko machine to which the present invention is applied. In FIG. 1, reference numeral 1 denotes a pachinko machine (game machine), which is a credit system in which a predetermined number of balls are stored in an internal microcomputer in a process of performing a pachinko game. In this specification (and also in the drawings), a pachinko ball is described (or displayed in the drawing) as a ball or a ball (for example, a prize ball or a hit ball). The meaning of pachinko balls, which is expressed appropriately according to the way pachinko balls are handled (how to process). Although the expressions are mixed, the balls and spheres are not different concepts, but according to the convenience of explanation. I just use them properly.

The pachinko machine 1 includes a frame-shaped front frame 11 as a portion visible on the front side, a metal frame (glass frame) 12 provided at an opening of the front frame 11 and supporting glass, and a game board 13. , A front display panel 14, and a front operation panel 15 below the front display panel 14. Front frame 11
Is supported by a wooden frame 16 on which the pachinko machine 1 is installed so as to be openable and closable, and similarly, the metal frame 12 is supported by the front frame 11 so as to be openable and closable. The front frame 11 is made of resin and has a predetermined colorful color. The front display panel 14 is formed in a curved shape such that the front side protrudes slightly and rises slightly. The front display panel 14 has an upper plate 21 for receiving a pachinko ball as a prize ball, and a credit number display on the front side. 22, Settlement button 2

The credit number display 22 displays the number of pachinko balls held by the player as credits, up to a maximum of 250 pieces. Specifically, when the upper plate 21 becomes full, Number of balls over 21 is 2
Memorize in the range up to 50, display the number of memorized, 2
Balls exceeding 50 are discharged to a lower plate 32 described later. The reason for limiting the number of credits to 250 is to match the range of "1 byte" of the microcomputer and to the range of credits in the rotary slot machine (so-called pachislot) (for example, currently the maximum number of credits is 50: (The number of medals). The credit number display 22 is, for example, 3 LEDs using a large LED of 7 segments.
The number of credits is displayed in units of one to the hundreds. Note that the credit number display 22 is not limited to a 7-segment LED, and may be configured using, for example, a dot LED, a liquid crystal, a fluorescent display tube, or the like.

In the case of the present embodiment, the credit number display 22 also has a function of displaying a discharge error (for example, displaying as CE). The discharge error includes, for example, a trouble in discharging the prize balls, a trouble in the number of balls to be lent, and the like, and in these cases, the credit number display 22 displays a discharge error to notify the player. The payment button 23 is for paying out credits. When the payment button 23 is pressed, the number of balls corresponding to the credit number at that time is paid out and discharged to the lower plate 32. The upper tray ball removal switch 24 is a push button for turning on a solenoid (not shown) for opening and closing a passage connecting the upper tray 21 and the ball of the upper tray 21 to a ball storage tray 32 to be described later. When the pullout switch 24 is pressed, the blinking indicator 25 during the pulling out of the ball flashes to notify the player. It should be noted that the blinking indicator 25 during ball removal

When the ball-drawing lever 33 is moved, for example, to the left, the lower bottom of the ball storage tray 32 is partially opened. The ball can be discharged downward. The overflow lamp 34 is arranged so as to be built in the side wall portion of the ball storage tray 32, and
When the ball 2 is full, it lights up to notify the player. When the player operates the ball removal lever 33 in accordance with the lighting of the overflow lamp 34 to release the ball in the ball storage tray 32, the overflow state is resolved.

The firing operation handle 35 is used to operate a firing device for bouncing pachinko balls arranged in a line at a firing position one by one into a game area on the front of the game board 13. . The firing operation handle 35 is coated with a thin metal film over the entire outer periphery thereof, so that a touch sensor (not shown) is provided so that a state in which the player grips the handle can be detected by the conductivity of the metal. Is provided. On the left side of the firing operation handle 35 in the figure, a firing operation switch (variable resistance for flying distance adjustment) 35a is arranged, and the operation of the firing operation switch 35a controls the strength of the firing (for example, the flying distance of the ball). Is adjustable. Launch intensity level LED3
Reference numeral 6 denotes a firing intensity level (flying distance of the ball) that is changed by operating the firing operation switch 35a. The firing intensity level can be determined by, for example, the number of lit LEDs. The single shot switch 37 is used to temporarily stop firing of the ball irrespective of the operation of the shooting operation handle 35, and is used, for example, when shooting a single shot of a ball.

At the top of the front frame 11 of the pachinko machine 1, there is provided a big hit indicator 41 which lights up when a big hit of the accessory device occurs. The metal frame 12 is supported by the front frame 11 so as to be openable and closable,
Normally, the key is inserted into the locking hole 51 and operated to lock the front frame 11 by the locking device.
When the metal frame 12 is opened, the locking device is unlocked and opened by inserting a predetermined key into the locking hole 51 and rotating the locking device. The game board 13 is made of, for example, a wooden veneer, and the front side thereof is a game area. The game area can take any configuration, for example, those belonging to the so-called first type, those belonging to the second type,
Alternatively, there is a type belonging to the third type, and any type of pachinko game can be applied to the present invention. In the present embodiment, those belonging to the second type are employed.

That is, a rail 61 for guiding a bouncing ball to the upper portion of the game board 13 is disposed around the game area, and a center accessory device (variable) is provided at a substantially central portion inside the rail 61. A winning device) 62, a tulip-type ordinary electric start port 63 is disposed below the center accessory device 62, and ordinary design gates 64 and 65 are disposed above and below the normal electric start port 63, respectively. The center accessory device 62 is a first disadvantage that is disadvantageous for a player who prevents a ball that has risen upright and flowed down from flowing into the inside.
A pair of movable pieces (movable members) that can be converted into a state (closed state) and a second state (open state) that is advantageous to a player that receives the ball that has flowed down with its upper end outward and receives the ball into the interior. ) 66a, 66b and movable pieces 66a, 66b
A general winning port and a special winning port (so-called V winning port: continuous winning port) into which the balls accepted by the player enter are provided.

When a ball wins in the ordinary electric starting port 63, the movable pieces 66a and 66b of the center accessory device 62 enter a second state (open state) in which the ball can be easily received. When a win is made in the mouth (when a V is won), the game mode shifts to a special mode game state (big hit state). In this special mode game state, the movable piece performs opening and closing operations at a maximum of 18 times, and it is possible to repeat the special mode game for a maximum of 15 cycles, for example, on the condition of V winning as one cycle. Therefore, the player can get more balls and enjoy higher profits. Each of the ordinary symbol gates 64 and 65 has a gate through which only one ball can pass, and when the ball passes through the gate, the symbol (for example, a number) of the ordinary symbol display 63a arranged in the ordinary electric starting port 63 is displayed. When the number is changed to a specific value (for example, “7”), the tulip of the ordinary electric starting port 63 is operated by electric operation and is opened for a predetermined time. Normally, the electric start port 63 normally closes the tulip, but is configured to open the tulip under certain conditions as described above. Further, as will be described later in detail, the probability of opening a tulip is changed by the probability setting device 75.

Further, at an appropriate position in the game area, a plurality of hitting direction conversion members (not shown) called windmills are rotatably installed, and a number of obstacle nails (not shown) are planted.
Further, an out-ball collecting port 69 is formed at the lower center of the game area.

Next, FIG. 2 is a view showing the structure of the back mechanism of the pachinko machine 1. As shown in FIG. In FIG. 2, the main components of the back mechanism of the pachinko machine 1 are a storage tank (upper tank) 71, a ball outlet gutter 72, a relay board (external terminal board) 73, a ball discharging device 74, a probability setting device 75, a ball setter. There are a cover 76, an accessory control circuit board 77, a speaker 78, a firing control circuit board 79, an overflow switch 80, a safe ball processing unit 81, and a base frame body 84 of a back mechanism board. The base frame 84 is made of a synthetic resin, and a mounting portion of the base frame 84 is fixed to a mounting frame integrally formed with the resin front frame 11 of the pachinko machine 1. Then, various unit components (corresponding to a mechanism) such as a storage tank 71, a ball outlet gutter 72, a relay base 73, a ball discharge device 74,
A speaker 78, an overflow switch 80, a safe ball processing unit 81, and the like are attached (for example,
These various unit components and the base frame 84 are collectively referred to as a back mechanism panel 90 as a general concept. Note that the probability setting device 75, the ball pulling cover 76, the accessory control circuit board 77, and the emission control circuit board 79 may be mounted on the base frame 84.

The storage tank 71 stores balls before being discharged. The shortage of the number of balls in the storage tank 71 is detected by a replenishment sensor (see FIG. 5). The ball is replenished. The balls in the storage tank 71 are guided by the ball discharge gutter 72 and discharged by the ball discharge device 74. An overall view of the ball outlet gutter 72 is shown in FIG. The ball outlet gutter 72 is not particularly limited, but is formed into two strips so that a large amount of balls can be discharged in a short time, and a ball leveling member 91 for preventing the weight of the ball in the middle thereof.
And a standby ball detector (not shown). Further, such a two-row configuration is the same for the inside of the ball discharging device 74 . The relay base 73 relays the input of AC power and the transmission and reception of signals with the hall management device. The probability setting device 75 changes the probability of winning the electric tulip at the ordinary electric start port 63.
The setting is as follows. Specifically, the setting contents are as follows.

[Contents of Probability Control] The pachinko machine 1 of 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. The firing control circuit board 79 performs control necessary for firing the ball, and a base of the firing control circuit is housed in a predetermined case. As the firing device, a type using a rotary solenoid (not shown) is used, and the firing 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. Each time the safe solenoid is turned on once, the safe ball processing unit 81 moves and discharges only one safe ball, and then immediately holds the next ball, thereby responding to the prize ball discharge. To discharge safe balls. As described above, by temporarily holding the safe ball, it is possible to confirm that the safe ball has actually been generated by winning, thereby preventing fraud and avoiding trouble with the player.

[Arrangement Structure of Emission Control Board] Next, the arrangement structure of the emission control board to which the present invention is applied will be described in detail. FIG. 3 is an enlarged view of the vicinity of the mounting portion of the emission control board. In FIG. 3, the storage space 101 of the storage tank 71 and the relay board 73 are provided above the base frame 84.

FIG. 5 is a view in which the base frame 84 is viewed from the direction of the game board 13 (that is, from the front side of the pachinko machine 1). It is in a state of being fixed to the body 84. In FIG. 5, the relay board 7
3, a ball discharging device 74 and the like are shown, and a supply switch 151 and a prize ball lamp 152 are arranged below the storage tank 71 (not visible). Also,
The central portion of the base frame 84 is largely open, and this opening is a space for mounting the center accessory device 62, that is, a central opening 84K. Emission control base 12
A wiring processing chamber 160 is formed in the base frame body 84 between the recessed chamber 110 in which the storage tank 71 is stored and the storage tank 71. , And a wall that defines the recessed portion 110 and is formed as a space that is long in the lateral direction. Upper connectors 131 to 133 connected to emission control board 120
The wiring 137 of the connectors 131 to 133 is housed in the wiring processing chamber 160 together with other wiring.

The wiring processing chamber 160 is not limited to this part, but is also formed continuously on the right side (the right side in FIG. 5) of the base frame 84. In the middle of the wiring processing chamber 160, the wiring arrangement member 1 may protrude from the side wall.
The wiring arrangement members 161 are provided with wirings 137, 170, and 1 housed in the wiring processing chamber 160.
It has a function of arranging wiring so that 80 does not come out of the wall. Further, the wirings 137, 170, and 180 housed in the wiring processing chamber 160 are sometimes bundled and fastened by a resin band 162. The wiring 170 shown in FIG. 5 is connected to the overflow switch 80, the emission control circuit board 79, and the like through wiring openings 171 to 173 formed in the base frame 84 (see FIG. 2). The wiring openings 171 to 173 are formed to allow the wiring to pass from the front side to the back side of the base frame 84.
On the other hand, a wiring 180 shown in FIG. 5 is connected to various electric components arranged on the front display panel 14 and the front operation panel 15, and a wiring 181 is connected to the ball discharging device 74 and the like. Reference numeral 190 denotes a striking lamp disposed substantially at the center of the relay base 73, reference numeral 191 denotes a ball discharge passage which opens in the upper plate 21, reference numeral 192 denotes an out port, and reference numeral 193 denotes a safe ball collecting unit for collecting safe balls. The safe ball collecting unit 193 collects safe balls through a safe ball port (not shown) and guides them to the safe ball processing unit 81.

In this embodiment, when a predetermined mechanism, that is, the ball outlet gutter 72 is attached to the base frame 84 in this embodiment, a recess having a fixed volume is provided between the ball outlet gutter 72 and the base frame 84. A chamber-shaped space, that is, a concave chamber 110 is formed, and the discharge control board 120 is housed and arranged in the concave chamber 110. In this case, the concave chamber portion 110 is an empty space defined by the ball outlet gutter 72 and the wall of the base frame body 84 below the storage tank 71, and the discharge control board 120 is attached by effectively using the empty space. It will be. Therefore, the limited space of the back mechanism in the pachinko machine 1 can be effectively used, and the hollow chamber 110, which is an empty space, is protected by the ball outlet gutter 72 and the base frame 84, so that the discharge control is performed. The base 120 can be sufficiently protected.

More specifically, even if there is a falling ball from the upper storage tank 71 or the like, the ball does not collide with the discharge control base 120 stored in the recess 110, or the operator controls the discharge control during maintenance and inspection. The emission control board 120 can be reliably protected without giving an impact by contacting the board 120. As a result, even if the discharge control board 120 is mainly composed of a microcomputer, there is no collision or impact due to a falling ball or the like, so that there is a possibility that a control error or a failure of the pachinko machine 1 due to this will be caused. Can be eliminated. Also, since the mounting position of the discharge control board 120 is near the wiring processing chamber 160,
The wiring 137 related to the discharge control board 120 can be housed in the wiring processing chamber 160 and connected without being brought out of the base frame body 84, and the wiring processing can be improved. More specifically, since the wiring is neatly housed in the wiring processing chamber 160 directly from the emission control board 120, the wiring does not need to be routed on the base frame 84 or the like as in the related art. It is possible to eliminate the problem that the worker sometimes hooks a finger or a tool on the wiring.

The position, shape, etc. of the recess 110 are as follows.
The present invention is not limited to the type of the above-described embodiment, but can be appropriately changed depending on the type of the gaming machine, and may have any shape within the scope of the object of the present invention. Further, the control board arrangement structure of the gaming machine according to the present invention is not limited to the example applied to the pachinko machine of the credit system in part, but can be applied to all other pachinko machines. In addition, the same concept can be applied to a game machine using a pachinko ball as a game medium, regardless of the model, in which a control base is arranged.
