<Basic configuration of gaming machine>
FIG. 1 is a front view showing an example of a gaming machine according to this embodiment, FIG. 2 is an oblique view showing an example of the back side of the gaming machine according to this embodiment, and FIG. 3 is a block diagram showing the configuration of a gaming control device provided in the gaming machine according to this embodiment.

In the gaming machine 1 shown in Figure 1, an inner frame (opening/closing frame) 3 is attached so as to be openable and closable to an outer frame 2 which is attached to the island structure of a gaming hall, and a glass frame 4 is attached so as to be openable and closable to this inner frame 3.
A window 4a is formed in the glass frame 4, and a transparent plate (glass plate) 4b is attached to the window 4a. A game board 10 having a board surface from which game balls are shot out is attached to the inner frame 3, and a game area 10a in which game balls can roll and flow down is formed between the board surface of the game board 10 and the transparent plate in front of it. The transparent plate 4b is, for example, a glass plate, and is removably fixed to the glass frame 4.

The glass frame 4 is connected to the outer frame 2 via a hinge mechanism 5 at one end in the left-right direction (e.g., the left side when facing the gaming machine), and can rotate around the hinge mechanism 5 in a direction that opens the other end in the left-right direction (e.g., the right side when facing the gaming machine) from the outer frame 2. The glass frame 4 covers the gaming board 10 together with the transparent plate, and can open the inner part of the outer frame 2 including the gaming board 10 by rotating like a door around the hinge mechanism 5. A lock mechanism is provided at the other end of the glass frame 4 to fix the other end of the glass frame 4 to the outer frame 2. The fixation by the lock mechanism can be released by a dedicated key. The glass frame 4 is also provided with an open detection switch 252 that detects whether the glass frame 4 is released from the outer frame 2.

A tray unit 7 having storage trays 6 (upper tray 6a and lower tray 6b) for storing game balls is provided at the bottom of the glass frame 4 (the lower part of the window 4a). The tray unit 7 is equipped with an effect button 8 (Figure 1) that the player can press, a cross key 600 with which the player can perform various selection operations, and an ejection button 9 for ejecting the game balls stored in the lower tray 6b outside the gaming machine.
The effect button 8 is only enabled when, for example, a message to operate the effect button 8 is displayed on the image display device 31 described later. The effect button 8 is provided with an effect button detection switch 8a (see FIG. 3), and when the effect button detection switch 8a detects an operation by the player, a further effect is executed in response to this operation.
Furthermore, the cross key 600 is provided with cross key detection switches (up key detection switch, down key detection switch, left key detection switch, and right key detection switch).

The operating handle 11 is provided on the lower right side of the glass frame 4. When the player touches the operating handle 11, the touch sensor 11a (see FIG. 3) inside the operating handle 11 detects that the player has touched the operating handle 11 and transmits a touch signal to the launch control board 75. When the launch control board 75 receives a touch signal from the touch sensor 11a, it allows the launch solenoid 12a to be energized. Then, by changing the rotation angle of the operating handle 11, the knob of the launch volume 11b rotates. A voltage corresponding to the detected angle of this launch volume 11b is applied to the launch solenoid 12a provided in the game ball launch mechanism. Then, when a voltage is applied to the launch solenoid 12a, the launch solenoid 12a operates according to the applied voltage, and the game ball is launched into the game area 10a of the game board 10 with a strength corresponding to the rotation angle of the operating handle 11.

An outer rail R1 and an inner rail R2 are provided around the play area 10a of the play board 10. These outer rail R1 and inner rail R2 guide the play ball launched from the play ball launching mechanism to the upper part of the play area 10a when the operating handle 11 is operated. The play ball guided to the upper part of the play area 10a falls within the play area 10a. At this time, the game ball falls unpredictably due to multiple nails and windmills provided in the play area 10a.
A center member 12 is disposed approximately in the center of the game board 10. The center member 12 is provided with an image display device 31 such as a liquid crystal display device, and a performance prop device 32 shaped like a "sword."

In addition, a first starting hole 13 through which game balls can enter is provided in the game area 10a at the lower center of the center member 12. A second starting hole 14 is provided below the first starting hole 13. The second starting hole 14 has an opening/closing door 14b, and is controlled to move between a first state in which the opening/closing door 14b is kept closed and a second state in which the opening/closing door 14b is open. Therefore, when the second starting hole 14 is in the first state, there is no chance of a game ball entering, and when it is in the second state, there is an increased chance of a game ball entering.
In this embodiment, when the second starting hole 14 is controlled to the first mode, a game ball is prevented from entering the second starting hole 14. However, if there are fewer opportunities for a game ball to enter when the second starting hole 14 is controlled to the first mode than when the second starting hole 14 is controlled to the first mode, a game ball may enter the second starting hole 14 when the second starting hole 14 is controlled to the first mode. In other words, the first mode includes a state in which it is impossible or difficult for a game ball to enter the second starting hole 14.

The first start hole 13 and the second start hole 14 are provided with a first start hole detection switch 13a (see FIG. 3) and a second start hole detection switch 14a, respectively, which detect the entrance of a game ball, and when these detection switches detect the entrance of a game ball, a lottery for the right to play a jackpot game, which will be described later (hereinafter, referred to as a "jackpot lottery") is held. Also, when the first start hole detection switch 13a and the second start hole detection switch 14a detect the entrance of a game ball, a predetermined prize ball (for example, three game balls) is paid out.
In the gaming machine 1 of this embodiment, when a gaming ball enters the first start hole 13 and the second start hole 14, for example, three gaming balls are paid out, but it is not necessary to pay out a gaming ball when it enters. Also, the number of payouts may be different for each start hole, for example, three for the first start hole 13 and one for the second start hole 14.

Gates 15 through which game balls can pass are provided in the game areas 10a on both sides of the center member 12. The gates 15 are provided with gate detection switches 15a (see FIG. 3) that detect the passage of the game ball, and when the gate detection switches 15a detect the passage of the game ball, a lottery for a normal symbol, which will be described later, is held.
Furthermore, a first large winning hole 16 and a second large winning hole 17 into which game balls can enter are provided in the game area 10a on the right side of the center member 12. For this reason, the game balls are configured not to enter the first large winning hole 16 and the second large winning hole 17 unless the game balls are shot out with great force by rotating the operating handle 11 greatly.

The first large prize opening 16 is normally kept closed by the opening/closing door 16b, preventing game balls from entering. In contrast, when a jackpot game, which will be described later, is started, the opening/closing door 16b opens and functions as a tray that guides game balls into the first large prize opening 16, allowing the game balls to enter the first large prize opening 16. A first large prize opening detection switch 16a is provided in the first large prize opening 16, and when this first large prize opening detection switch 16a detects the entry of a game ball, a preset number of prize balls (e.g., 15 game balls) are paid out.

The second large prize opening 17 is normally kept in a closed state by the movable piece 17b, making it impossible for game balls to enter. On the other hand, when a big win game described later is started, the movable piece 17b is actuated and opened, and this movable piece 17b functions as a guide path that guides the game ball into the second large prize opening 17, making it possible for the game ball to enter the second large prize opening 17. The second large prize opening 17 is provided with a second large prize opening detection switch 17a, and when this second large prize opening detection switch 17a detects the entry of a game ball, a preset prize ball (for example, 15 game balls) is paid out.
Furthermore, the gaming area 10a is provided with a plurality of general winning holes 18. When a gaming ball enters each of these general winning holes 18, a predetermined number of prize balls (for example, 10 gaming balls) are paid out.

At the bottom of the game area 10a, there is an outlet 19 for discharging game balls that do not enter any of the general winning opening 18, the first starting opening 13, the second starting opening 14, the first large winning opening 16, and the second large winning opening 17.
The image display device 31 displays images during standby when no game is being played, and displays images according to the progress of the game. In particular, when a game ball enters the first start hole 13 or the second start hole 14, a performance pattern 35 that notifies the player of the lottery result is displayed in a variable manner.
The performance pattern 35 is, for example, a scrolling display of three patterns (numbers), namely a first pattern (left pattern), a second pattern (right pattern), and a third pattern (center pattern), and the scrolling is stopped after a predetermined time has elapsed to display an array of specific patterns (numbers).

This gives the player the impression that a lottery is currently being drawn while the symbols are scrolling, and the player is notified of the lottery results by the symbols displayed when the scrolling stops. By displaying various images and characters during the varying display of the performance symbols 35, the player is given a high sense of expectation that he or she may win a jackpot.
Although not shown, a fourth symbol is displayed on the image display device 31 in addition to the effect symbol 35. The fourth symbol is a symbol that indicates a changing state of the effect symbol 35 used to notify the lottery result of the big win lottery process.
It should be noted that the fourth symbol does not necessarily have to be displayed on the image display device 31, and may be displayed by a separate fourth symbol display lamp.

A pair of performance lighting devices 33, one on each side, are mounted on the upper portion of the glass frame 4. Each performance lighting device 33 is equipped with a number of lights, and various performances can be performed by changing the irradiation direction and emission color of each light.
Each of the performance lighting devices 33 is equipped with a plurality of lights, and various performance effects can be created by changing the direction of light irradiation and the color of light emitted by each light.
Furthermore, although not shown in FIG. 1, the gaming machine 1 is provided with an audio output device 34 (see FIG. 3) consisting of a speaker, which outputs BGM (background music), SE (sound effects), etc. in addition to the various presentation devices described above, thereby enabling presentations using sound.

At the lower left side of the game area 10a, there are provided display areas including a first special pattern display device 20, a second special pattern display device 21, a normal pattern display device 22, a first special pattern reserved display device 23, a second special pattern reserved display device 24, a normal pattern reserved display device 25, and a round number display device 26, which will be described later.
The first special symbol display device 20 notifies the player of the result of the lottery for the big win, which is triggered by the entry of a game ball into the first starting hole 13, and is composed of multiple LEDs. In other words, multiple special symbols corresponding to the lottery results for the big win are provided, and the lottery results are notified to the player by displaying special symbols (lighting modes) corresponding to the lottery results for the big win on the first special symbol display device 20. The special symbols displayed in this way are not displayed immediately, but are displayed in a variable manner (blinking) for a predetermined period of time and then displayed stationary.
More specifically, when a game ball enters the first starting hole 13, a lottery for a big win is held, but the result of this lottery is not immediately notified to the player, but is notified to the player after a predetermined time has passed. Then, after the predetermined time has passed, a special symbol corresponding to the lottery result for the big win is stopped and displayed, so that the lottery result is notified to the player.

The second special pattern display device 21 is intended to notify the result of the jackpot lottery that is triggered when a gaming ball enters the second starting hole 14, and its display mode is the same as the display mode of the special pattern in the first special pattern display device 20.
The normal symbol display device 22 is for notifying the result of a lottery for normal symbols, which is conducted when the game ball passes through the gate 15. As will be described in detail later, when a predetermined winning is won in the lottery for the normal symbols, the normal symbol display device 22 lights up, and then the second starting hole 14 is controlled to the second mode for a predetermined time. Note that the lottery result for this normal symbol is not immediately notified when the game ball passes through the gate 15, but the normal symbol is displayed in a variable manner, such as by flashing the normal symbol display device 22, until the predetermined time has passed.
Furthermore, when a game ball enters the first start hole 13 or the second start hole 14 and a lottery for a jackpot cannot be held immediately, such as during the variable display of special symbols or during a special game described below, the right to a lottery for a jackpot is reserved under certain conditions. More specifically, the right to a lottery for a jackpot reserved when a game ball enters the first start hole 13 is reserved as a first reservation, and the right to a lottery for a jackpot reserved when a game ball enters the second start hole 14 is reserved as a second reservation.

The upper limit of the number of reserved balls for each of these two reserves is set to four, and the number of reserved balls is displayed on the first special symbol reserved indicator 23 and the second special symbol reserved indicator 24, respectively.
The maximum number of reserved ordinary symbols is also set to four, and the reserved number is displayed on the ordinary symbol reserved display 25 in a manner similar to that of the first special symbol reserved display 23 and the second special symbol reserved display 24.
The round number display 26 is for notifying the number of rounds of a round game played during a special game, which will be described later.

The game information output terminal board 27 is connected to the main control board 50 by wiring, and is provided with a connector for connecting to a hall computer or the like of an amusement facility.
The power supply board 76 converts the power supply voltage supplied from the power plug 77 into a predetermined voltage and supplies it to each control board. The power supply board 76 also has a backup power supply consisting of a capacitor, which monitors the power supply voltage supplied to the gaming machine and outputs a power interruption detection signal to the main control board 50 when the power supply voltage falls below a predetermined value. More specifically, when the power interruption detection signal becomes high level, the main CPU 50a becomes operable, and when the power interruption detection signal becomes low level, the main CPU 50a becomes inoperative. The backup power supply is not limited to a capacitor, and may be, for example, a battery, or a combination of a capacitor and a battery.

The performance control board 55 mainly controls each performance during play, standby, etc. This performance control board 55 is equipped with a sub-CPU 55a, a sub-ROM 55b, and a sub-RAM 55c, and is connected to the main control board 50 so as to be able to communicate in one direction from the main control board 50 to the performance control board 55.
The sub-CPU 55a reads out a program stored in the sub-ROM 55b and performs arithmetic processing based on a command transmitted from the main control board 50 or an input signal from the performance button detection switch 8a input via the lamp control board 65, and transmits corresponding data to the lamp control board 65 or the image control board 70 based on the processing. The sub-RAM 55c functions as a work area for data during arithmetic processing by the sub-CPU 55a.

The sub-ROM 55b of the performance control board 55 stores programs for performance control, data required for various games, and tables.
For example, a variable presentation pattern determination table (not shown) for determining a presentation pattern based on a variable pattern designation command received from the main control board 50, a presentation pattern determination table (not shown) for determining a combination of presentation patterns 35 to be stopped and displayed, etc. are stored in the sub-ROM 55b. Note that the above-mentioned tables are merely examples of characteristic tables among the tables in this embodiment, and many other tables and programs (not shown) are provided in the course of the game.

The sub-RAM 55c of the performance control board 55 has multiple memory areas.
The sub-RAM 55c is provided with a command receiving buffer, a game status storage area, a performance mode storage area, a performance pattern storage area, a performance symbol storage area, a judgment storage area (zeroth storage area), a first reserved storage area, a second reserved storage area, etc. The above-mentioned storage areas are merely examples, and many other storage areas are provided.
In addition, an RTC (real-time clock) 55d that outputs the current time is mounted on the performance control board 55. The sub-CPU 55a inputs a date signal indicating the current date and a time signal indicating the current time from the RTC 55d, and executes various processes based on the current date and time.
The RTC 55d normally operates on power from the gaming machine when power is supplied to the gaming machine, and operates on power supplied from a backup power source mounted on the power supply board 76 when the gaming machine is turned off. Therefore, the RTC 55d can measure the current date and time even when the gaming machine is turned off. The RTC 55d may be operated by a battery provided on the performance control board 55.

The payout control board 60 controls the launch of game balls and the payout of prize balls. This payout control board 60 is equipped with a payout CPU 60a, a payout ROM 60b, and a payout RAM 60c, and is connected to the main control board 50 so that it can communicate in both directions. The payout CPU 60a reads out a program stored in the payout ROM 60b and performs calculations based on input signals from a payout ball counting switch 251, which detects whether game balls have been paid out, and an opening detection switch 252, and transmits corresponding data to the main control board 50 based on the processing.

Also, the output side of the payout control board 60 is connected to a payout motor 250 of a prize ball payout device for paying out a predetermined number of prize balls from a game ball storage section to a player. The payout CPU 60a reads out a predetermined program from the payout ROM 60b based on a payout number designation command transmitted from the main control board 50, performs calculation processing, and controls the payout motor 250 of the prize ball payout device to pay out a predetermined number of prize balls to a player. At this time, the payout RAM 60c functions as a data work area during the calculation processing of the payout CPU 60a.
It also checks whether a game ball lending device (card unit) (not shown) is connected to the payout control board 60, and if the game ball lending device (card unit) is connected, it transmits launch control data to the launch control board 75 to allow the game balls to be launched.
In addition, a tray full detection switch 51 and a ball jam detection switch 52 are connected to the dispensing control board 60.

The launch control board 75 permits launch when it receives launch control data from the payout control board 60. Then, it reads out the touch signal from the touch sensor 11a and the input signal from the launch volume 11b, controls the energization of the launch solenoid 12a and the ball feed solenoid 12b, and launches the game ball.
The firing solenoid 12a is a rotary solenoid. A firing member (not shown) is directly connected to the firing solenoid 12a, and the firing solenoid 12a rotates to rotate the firing member.
Here, the rotation speed of the launch solenoid 12a is set to about 99.9 (times/minute) based on the frequency based on the output cycle of the crystal oscillator provided on the launch control board 75. As a result, the number of launched game balls per minute is about 99.9 (balls/minute), since one ball is launched per rotation of the launch solenoid. In other words, a game ball is launched approximately every 0.6 seconds.
The ball-feeding solenoid 12b is composed of a linear solenoid, and sends out the game balls on the upper tray 6a (see FIG. 1) one by one toward the ball-feeding member directly connected to the launch solenoid 12a.

The lamp control board 65 is connected to the performance control board 55 so as to be able to communicate in both directions, and its input side is connected to the performance button detection switch 8a provided on the performance button 8.

The lamp control board 65 also controls the supply of electricity to drive sources such as solenoids and motors that operate the performance accessory device 32. In this embodiment, the performance button 8 is configured to protrude, so the performance accessory device 32 includes the performance button 8.
The image control board 70 is connected to the performance control board 55 so as to be capable of two-way communication, and the image display device 31 and the audio output device 34 are connected to its output side.

Next, the performance button 8 is incorporated in the center part of the plate unit 7.
The effect button 8 is configured to be movable between a normal operation position (not shown), a depressed position retracted below the normal operation position, and a protruding operation position protruding above the normal operation position. The effect button 8 is also configured to be capable of being depressed from any position including the normal operation position and the protruding operation position to the depressed position.
In addition, in this specification, the detailed structure of the effect button 8 is disclosed in, for example, JP 2013-116168 A, so description thereof will be omitted.

The image control board 70 in FIG. 7 does not necessarily need to have an independent data ROM, but it can have an independent data ROM and use the integrated data ROM 92 as an expansion area.

Fig. 8 is a schematic front view of the performance board case of this embodiment. Fig. 9 is a schematic perspective view of the performance board case of this embodiment. Figs. 10 and 11 are exploded perspective views of the performance board case. Fig. 12 is a diagram illustrating parts to be attached to the performance board case.
An overview of the performance board case of this embodiment will be described with reference to Figures 8 to 11.
As shown in Figures 8 to 11, the performance board case 100 comprises a board base 100B (front case piece) and a board cover 100A (rear case piece).
By combining the board cover 100A and the board base 100B, a performance board case 100 (base member) is formed as a box that contains the performance board.
The board cover 100A that constitutes the performance board case 100 further includes a ROM cassette 40 (mounting member), a heat sink 500, a heat sink cover 400, etc., at its rear side.

As shown in Figures 10 and 11, the board base 100B and the board cover 100A each have a base-side board accommodating section 101 and a cover-side board accommodating section 102 for accommodating the performance control board 55 and the image control board 70, respectively.
The performance board case 100 has an inner container (substrate container) made up of a base side substrate container 101 (FIG. 10) provided on the substrate base 100B and a cover side substrate container 102 (FIG. 11) provided on the substrate cover 100A, and contains the performance control board 55 and the image control board 70 in the inner container. The performance control board 55 and the image control board 70 are connected via a connector and are contained in the performance board case 100 in an integrated state.
In the board cover 100A, openings 115, 116 (Figure 10) are provided at locations corresponding to the positions of the connector 83 and segmented LCD 85 on the performance control board 55, and the connector 83 and segmented LCD 85 are exposed on the rear side of the board cover 100A (Figures 8 and 9).
Since the connector 83 is exposed, it is easy to connect to the main control board 50 using a harness, and the display on the segmented LCD 85 can be seen through the board cover 100A, which is very convenient.

In addition, the base side substrate accommodating portion 101 and the cover side substrate accommodating portion 102 each have a plate portion formed in an approximately rectangular shape and a flange portion protruding from the peripheral edge of each plate portion and surrounding one side surface of each plate portion (Figures 10 and 11).
Of the flange portions constituting the base side substrate accommodating portion 101 of the substrate base 100B, five L-shaped hook pieces 101a are formed on each of the portions protruding along the two long sides of the substrate base 100B (Figure 10).
On the other hand, among the flanges constituting the cover-side board accommodation portion 102 of the board cover 100A, the portions protruding along the two long sides of the board cover 100A are formed in a double-wall shape, and an insertion groove 102a into which the hook piece 101a of the board base 100B can be inserted is provided between the walls forming the double wall. Also, a hook piece is formed in each insertion groove 102a (FIG. 11).

When the board cover 100A and the board base 100B are assembled together, the hook pieces 101a of the board base 100B are inserted into the insertion grooves 102a of the board cover 100A.
Then, the board base 100B is slid in the direction of the arrow α in Figures 10 and 11 along the left-right direction relative to the board cover 100A. Then, the hook piece of the board cover 100A and the hook piece of the board base 100B engage with each other, so that the board base 100B and the board cover 100A are combined so that they will not come off unless they move each other in the opposite direction to the arrow α. When combined in this way, the board cover 100A and the board base 100B form a box-shaped inner container part (board container part) that is shielded from the outside by the base side board container part 101 and the cover side board container part 102, and the performance control board 55 and the image control board 70 are stored in the inner container part. This can suppress the possibility of the performance control board 55, the image control board 70, etc. being illegally replaced.

In this embodiment, the board base 100B and the board cover 100A are sealed by a fastening seal portion 450A with the performance control board 55 and the image control board 70 sandwiched between them.
As shown in Figures 8 and 9, at appropriate positions along the edges of the performance board case 100, there are provided fastening seal portions 450A for closing (sealing) the board base 100B and the board cover 100A.

As shown in FIG. 10, the board base 100B and the board cover 100A each include latched portions 120, 121 that form a fastening seal portion 450A.
The fastening sealing part 450A locks the board base 100B and the board cover 100A in a closed (sealed) state by driving a locking member (rivet pin) into the fastening holes of the locked parts 120 and 121 to lock the locked parts 120 and 121 as described below. By removing the locking member (rivet pin) driven into the fastening holes of the locked parts 120 and 121, the performance board case 100 consisting of the board base 100B and the board cover 100A becomes openable.
Sealing or closing the performance board case 100 means making the performance board case 100 in an unopenable state unless the sealing member driven into the sealed portion is removed or the fastening (seal) is destroyed.

On the other hand, as shown in Figures 8 and 9, the attachment point of the ROM cassette 40 on the performance board case 100 is provided with a fastening locking portion 450B for fastening (locking) the ROM cassette 40 to the performance board case 100.
The fastening locking portion 450B is a fastening locking portion for fixing (locking) the ROM cassette 40 to the performance board case 100 when the board base 100B and the board cover 100A are closed (sealed) by the fastening sealing portion 450A.
The fastening locking portion 450B locks (fixes) the ROM cassette 40 to the performance board case 100 (board cover 100A) by driving a locking member (rivet pin) into the fastening holes of the locked portions 42, 109 as described below, thereby locking the locked portions 42, 109. The ROM cassette 40 can be removed from the board cover 100A by removing the locking member (rivet pin) driven into the fastening holes of the locked portions 42, 109. When removing the ROM cassette 40, it is necessary to release the lock by the fastening locking portion 450B, but it is not necessary to release the seal by the fastening sealing portion 450A.
Furthermore, when opening the performance board case 100, it is necessary to release the seal by the fastening sealing portion 450A, but it is not necessary to release the lock by the fastening locking portion 450B.
The different fastening modes of the fastening seal portion 450A and the fastening lock portion 450B will be described in detail later.

As shown in FIG. 12, the board cover 100A has an opening 103 at a position corresponding to the image control board 70 on the rear side, and further has a heat sink 500 on the rear side so as to close the opening 103.
Furthermore, the board cover 100A includes a heat sink cover 400 that covers the heat sink 500 on the rear side of the board cover 100A.
The board cover 100A also has a cassette attachment portion 104 on its rear side for attaching the ROM cassette 40 thereto.
The cassette attachment portion 104 is provided with a positioning pin 105 that protrudes from the surface of the board cover 100A.
The positioning pin 105 is used to position the ROM cassette 40 when a worker attaches it to the performance board case 100 (board cover 100A), and fits into an insertion hole 45 (described later) provided in the ROM cassette 40 to secure the ROM cassette 40 to the performance board case 100 (board cover 100A).

In addition, the cassette mounting portion 104 has an opening 106 at a position corresponding to a connector 81 (first connector) protruding from the performance control board 55 contained in the performance board case 100, and the connector 81 is exposed from the opening 106.
When the ROM cassette 40 is attached to the cassette mounting portion 104 of the performance board case 100 (board cover 100A), the connector 81 of the performance control board 55 is connected to a connector 91 (fourth connector) provided on the integrated ROM board 90 contained in the ROM cassette 40.
The cassette attachment portion 104 also includes a multi-purpose claw portion 110 located near the positioning pin 105 in the figure. The characteristics of the claw portion 110 will be described in detail later.
Furthermore, the cassette mounting portion 104 is provided with an opening 107 provided at a position corresponding to a button battery that is detachably provided on the performance control board 55 contained within the performance board case 100, and a detachable cover 108 that covers the opening 107.
When it is necessary to install or replace a button battery in the battery holder 80 provided on the performance control board 55, the inside of the performance board case 100 can be accessed simply by removing the removable cover 108. There is no need to open the performance board case 100.

The cassette mounting portion 104 is provided with a locked portion 109 which, together with the locked portion 42 of the cassette case 40A, forms a fastening locking portion 450B when the ROM cassette 40 is normally mounted, and into which a locking member (rivet pin) is driven.
When the ROM cassette 40 is fastened to the board cover 100A (performance board case 100), the detachable cover 108 provided on the cassette mounting portion 104 cannot be removed, and the detachable cover 108 can be removed only after the ROM cassette 40 is removed from the board cover 100A (performance board case 100), thereby preventing unauthorized access to the inside of the performance board case 100.
Fastening the ROM cassette 40 to the board cover 100A (performance board case 100) not only secures the ROM cassette 40 (prevents it from being taken away), but also makes it possible to easily control whether or not access is possible to the inside of the performance board case 100.

Furthermore, as shown in FIG. 12, the side wall portion 104a of the cassette mounting portion 104 is provided with a first fixing portion 111 that fixes the first fixed portion 43 (described below) of the ROM cassette 40 when the ROM cassette 40 is attached to the board cover 100A, and a claw portion 110 that protrudes downward with a space 110a between it and the surface of the cassette mounting portion 104 and fixes the second fixed portion 44 between it and the surface of the cassette mounting portion 104.

13A and 13B are diagrams showing a ROM board on which an integrated data ROM is mounted, where FIG. 13A is a diagram showing the ROM board as viewed from the rear, and FIG. 13B is a diagram showing the ROM board as viewed from the front.
As shown in FIG. 13, the integrated ROM board 90 has a connector 91 on its front surface for connecting to the connector of the performance control board 55, and has an integrated data ROM 92 for the performance control board 55 and the image control board 70 on its rear surface.
14A and 14B are schematic diagrams of the ROM cassette, in which (a) is a schematic perspective view of the ROM cassette as viewed from the rear, and (b) is a view of the ROM cassette as viewed from the front.

The structure of the ROM cassette of this embodiment will be described with reference to FIGS.
As described above, the ROM cassette 40 is removably attached to the cassette mounting portion 104 of the board cover 100A in the performance board case 100.
The ROM cassette 40 includes a cassette body 40B that houses an integrated ROM board 90 therein, and a cassette case 40A that houses the cassette body 40B therein.
The cassette case 40A comprises an engaging portion 42 which constitutes the fastening engaging portion 450B together with an engaging portion 109 provided on the performance board case 100 (board cover 100A), a first fixed portion 43 which is fixed to the performance board case 100 (board cover 100A), and a second fixed portion 44.
The cassette body 40B has an insertion hole 45 into which a positioning pin 105 protruding from the cassette mounting portion 104 on the surface of the board cover 100A is inserted, and a connector 91 which is connected to the connector 81 of the performance control board 55 contained within the performance board case 100.

The connector 91 is provided on an integrated ROM board 90 housed in the cassette body 40B and protrudes from an opening 41 of the cassette body 40B.
As shown in FIGS. 15 and 16, the cassette body 40B is accommodated in the cassette body accommodating portion 46 of the cassette case 40A, and the cassette body 40B accommodates the integrated ROM board 90 in the ROM board accommodating portion 47. As shown in FIG.
The cassette body 40B is movable within the cassette case 40A in the direction of the longer side of the cassette case 40A. The ROM cassette 40 can be in a first state or a second state, which will be described below, depending on the position of the cassette body 40B relative to the cassette case 40A.

17A and 17B are diagrams for explaining the first state of the ROM cassette, where FIG. 17A is a diagram of the ROM cassette as viewed from above, and FIG. 17B is a diagram of the ROM cassette as viewed from below.
18A and 18B are diagrams for explaining the second state of the ROM cassette, where FIG. 18A is a diagram of the ROM cassette as viewed from above, and FIG. 18B is a diagram of the ROM cassette as viewed from below.
As shown in FIG. 17, in the first state, the cassette body 40B is in a position shifted toward the second fixed portion 44 within the cassette case 40A.
As shown in FIG. 18, in the second state, the cassette body 40B is in a state in which it is shifted toward the locked portion 42 and the first fixed portion 43 within the cassette case 40A.
The cassette case 40A has a notch 48 in the side wall on the long side on the side where the first fixed portion 43 is provided, near the first fixed portion 43. The function of this notch 48 will be described in detail below.

19 and 20 are diagrams explaining the procedure for attaching the ROM cassette to the performance board case.
FIG. 19 illustrates a case in which the ROM cassette can be correctly attached to the performance board case.
FIG. 19A shows the state of the cassette attachment portion 104 of the board cover 100A before the ROM cassette 40 is attached.
In the cassette mounting portion 104, the connector 81 of the performance control board 55 contained within the performance board case 100, the positioning pin 105 for positioning the cassette main body 40B, the claw portion 110, and the first fixing portion 111 are exposed.
In this state, the ROM cassette 40 is not attached to the performance board case 100, and removable parts of the performance board case 100 (such as the button battery mentioned above) can be accessed and removed.
As described above, the claw portion 110 is a member that protrudes downward leaving a space 110a between itself and the surface of the cassette mounting portion 104, and fixes the second fixed portion 44 between itself and the surface of the cassette mounting portion 104.

From this state, in FIG. 19(b), an attempt is made to attach the ROM cassette 40 in the first state (FIG. 17) to the cassette attachment portion 104.
As shown in Figure 19 (b), in the ROM cassette 40 in the first state, when the positioning pin 105 of the cassette mounting portion 104 is inserted into the insertion hole 45 of the cassette main body 40B, the claw portion 110 of the board cover 100A is accommodated within the cutout portion 48 of the cassette case 40A.
The claw portion 110 does not interfere with the cassette case 40A, and the operator can press the entire ROM cassette 40 down toward the performance board case 100, completely connecting the connector 91 of the cassette body 40B to the connector 81 of the performance control board 55. The first fixed portion 43 and the second fixed portion 44 of the cassette case 40A and the cassette body 40B can all abut against the surface of the cassette mounting portion 104 of the board cover 100A.
At this time, the first fixed portion 43 of the cassette case 40A is located on the opposite side of the notch 48 with the claw portion 110 in between.

According to this embodiment, with the positioning pin 105 of the performance board case 100 (cassette mounting portion 104) inserted into the insertion hole 45 of the cassette main body 40B, the connector 81 of the performance board case 100 and the connector 91 of the ROM cassette 40 can be connected simply by pushing the ROM cassette 40 straight down, so there is no need to worry about unnecessary stress being applied to both connectors, which could cause them to break.
However, at this stage when the ROM cassette 40 is still in the first state, the position of the locked portion 42 of the cassette case 40A does not coincide with the position of the locked portion 109 of the board cover 100A. Therefore, the locked portion 42 and the locked portion 109 cannot be locked together to fasten (lock) the ROM cassette 40 to the performance board case 100.
The cassette body 40B is positioned on the board cover 100A by the insertion holes 45 and the positioning pins 105, but as described above, the cassette case 40A is movable relative to the cassette body 40B.
That is, with the cassette body 40B attached to the board cover 100A, the ROM cassette 40 can be shifted from the first state to the second state (FIG. 18).

19(c), the cassette case 40A is slid in the direction of the arrow in the figure. At this time, the first fixed portion 43 moves toward the first fixed portion 111 provided on the side wall portion 104a of the cassette mounting portion 104, and the tip of the first fixed portion 43 moves in a direction to enter the space 110a between the claw portion 110 and the surface of the cassette mounting portion 104.
During this time, the claw portion 110 functions as a guide means for guiding the sliding movement of the cassette case 40A.

The cassette case 40A is slid and finally, as shown in Fig. 19(d), the ROM cassette 40 is completely in the second state. At this time, the first fixed portion 43 is completely inserted and fixed in the first fixed portion 111, and the tip 43a of the second fixed portion 43 is completely inserted and fixed in the space 110a below the claw portion 110.
Furthermore, since the position of the locked portion 42 coincides with the position of the locked portion 109 provided on the board cover 100A, the locked portion 42 and the locked portion 109 can be locked with a locking pin (sealing member) to fasten (lock) the cassette case 40A to the performance board case 100. The claw portion 110 functions as a locking (fixing) member for locking (fixing) the ROM cassette 40 to the board cover 100A.

The state shown in Figure 19 (d) is the installation state in which the ROM cassette 40 is attached to the performance board case 100 regardless of whether the cassette case 40A is engaged with the performance board case 100. In this state, the removable parts (such as a button battery) of the performance board case 100 cannot be attached or detached.
To remove the ROM cassette 40 from the performance board case 100, the procedure described in Fig. 19 can be reversed. That is, after releasing the fastening between the locked portion 42 and the locked portion 109, the cassette case 40A is slid in the direction opposite to the arrow in Fig. 19(c). As a result, when the ROM cassette 40 returns from the second state to the first state, the fixation of the first fixed portion 43 by the first fixing portion 111 and the fixation of the second fixed portion 43 by the claw portion 110 are released, resulting in the state shown in Fig. 19(b).
By pulling out the ROM cassette 40, the ROM cassette 40 can be removed from the performance board case 100.

The ROM cassette 40 can be attached to the performance board case 100 when it is in the first state (Figure 17), and locked in place in the performance board case 100 by switching it to the first state (Figure 18). On the other hand, the ROM cassette 40 in the second state cannot be attached to the performance board case 100.

FIG. 20 illustrates a case where the ROM cassette cannot be properly attached to the performance board case.
Figure 20(a) shows the cassette mounting part 104 in the same state as Figure 19(a). If an attempt is made to mount the ROM cassette 40 in the second state to the cassette mounting part 104 in this state, the state will be as shown in Figure 20(b).
19(b), in the ROM cassette 40 in the first state, when attempting to insert the positioning pin 105 of the cassette attachment part 104 into the insertion hole 45 of the cassette body 40B, the first fixed part 43 of the cassette case 40A rides up on the claw part 110 of the board cover 100A, causing the claw part 110 to interfere with the cassette case 40A. The second fixed part 44 also rides up on the side wall part 104a of the cassette attachment part 104.

In this state, the operator cannot push the entire ROM cassette 40 down toward the performance board case 100 to connect the connector 91 of the cassette body 40B to the connector 81 of the performance control board 55. The ROM cassette 40 is floating above the surface of the cassette mounting portion 104 of the board cover 100A.
The position of the engaging portion 42 of the cassette case 40A roughly coincides with the position of the engaging portion 109 of the board cover 100A, but since the ROM cassette 40 is floating above the surface of the cassette mounting portion 104, the engaging portion 42 and the engaging portion 109 cannot be engaged with each other.
If the worker forcibly pushes down the ROM cassette 40 in this state, there is a possibility that the cassette case 40A may be destroyed. However, the length of the positioning pin 105 provided in the cassette mounting part 104 is set to a length that does not allow the connector 81 on the performance board case 100 side and the connector 91 on the ROM cassette 40 side to come into contact in the case shown in Fig. 20, so even if the ROM cassette 40 is forcibly pushed down, there is no need to worry about stress being applied to both connectors, which may cause damage.
The claw portion 110 functions as a restricting member that does not restrict the attachment of the ROM cassette 40 in the first state to the performance board case 100, but restricts the attachment of the ROM cassette 40 in the second state to the performance board case 100.

Conventionally, rewriting and reusing programs and data stored in a program ROM implemented on the performance control board 50 or a data ROM implemented on the image control board 70 required complicated work.
The seal of the board case housing the performance control board 50 and the image control board 70 is broken and opened, the performance ROM is taken out from the board, and the data on the performance ROM is rewritten using a special device, and then the board is reinstalled on each board.
When performing this type of work, there was a problem in that the connector pins on the performance ROM could be damaged.
In response to such a problem, in the gaming machine of this embodiment, the performance ROM is an external component to the performance board case, and is housed in a cassette that is detachable from the performance board case, so there is no need to open and close the board case when rewriting the performance ROM, and there is no need to directly attach and detach the performance ROM to the board. In addition, because of the configuration described above, there is little risk of stress being applied to the performance ROM or the connector extending from the performance board, so there is no trouble of damaging the ROM or the performance board itself during the work process.
In the gaming machine of this embodiment, the efficiency and safety of the work involved in rewriting the performance ROM can be dramatically improved. In addition, the reuse of the performance ROM is promoted, and the manufacturing and development of gaming machines can be significantly made more efficient while reducing the environmental burden.

Furthermore, in this embodiment, the programs and data used by the performance control board 50 and the image control board 70 are consolidated into a single integrated ROM, so that by only removing and attaching the cassette ROM once, the ROM related to the performance control board 50 and the image control board 70 can be rewritten in one go.
When removing the ROM cassette 40, it is only necessary to release the lock at the fastening locking portion 450B, which has the sole role of fixing (locking) the ROM cassette 40 to the performance board case 100, and there is no need to release the lock at the fastening locking portion 450B to open the performance board case 100.
In this embodiment, the ROM containing programs and data for performance control can be replaced with significantly higher efficiency than in the past.

In addition, in the past, it was necessary to unclasp and open the board case just to replace a removable part (such as a button battery) inside the board case.
However, in this embodiment, by providing an opening in the cassette mounting portion for accessing the button battery, when the ROM cassette is attached and fastened to the board case, unauthorized access to the inside of the board case through the opening for accessing the button battery can be prevented, and at the same time, by simply removing the ROM cassette from the cassette mounting portion, the opening for accessing the button battery can be exposed, making it possible to perform tasks such as replacing the button battery without opening the board case.
