The operator pushes down the entire ROM cassette 40 toward the effect board case 100 without the claw part 110 interfering with the cassette case 40A, and the connector 91 of the cassette main body 40B and the connector 81 of the first effect board 55 are completely connected. can be connected to The first fixed portion 43 and the second fixed portion 44 of the cassette case 40A and the cassette main body 40B can all abut on the surface of the cassette mounting portion 104 of the substrate cover 100A.
At this time, the first fixed portion 43 of the cassette case 40A is located on the opposite side of the notch portion 48 with the claw portion 110 interposed therebetween.

According to this embodiment, the effect board case 100 can be removed by simply pushing down the ROM cassette 40 straight down while the positioning pins 105 of the effect board case 100 (cassette mounting portion 104) are inserted into the insertion holes 45 of the cassette main body 40B. Since the connector 81 and the connector 91 of the ROM cassette 40 can be connected, there is no risk of damage due to unnecessary stress being applied to both connectors.
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 match the position of the locked portion 109 of the substrate cover 100A. Therefore, it is not possible to fasten (lock) the ROM cassette 40 to the effect board case 100 by locking the locked portion 42 and the locked portion 109 .
The cassette main body 40B is positioned on the substrate cover 100A by the insertion holes 45 and the positioning pins 105, but as described above, the cassette case 40A is relatively movable with respect to the cassette main body 40B.
That is, with the cassette main body 40B attached to the substrate cover 100A, the ROM cassette 40 can be shifted from the first state to the second state (FIG. 18).

As shown in FIG. 19(c), the cassette case 40A is slid in the direction of the arrow in the drawing.

Furthermore, since the position of the locked portion 42 matches the position of the locked portion 109 provided on the substrate cover 100A, the locked portion 42 and the locked portion 109 are separated by the locking pin (sealing member). By locking, the cassette case 40A can be fastened (locked) to the effect board case 100. FIG. The claw portion 110 functions as a locking (fixing) member for locking (fixing) the ROM cassette 40 to the substrate cover 100A.

The state shown in FIG. 19(d) is an attached state in which the ROM cassette 40 is attached to the effect board case 100 regardless of whether or not the cassette case 40A is engaged with the effect board case 100. FIG. In this state, detachable parts (such as a button battery) of the effect board case 100 cannot be detached.
In order to remove the ROM cassette 40 from the effect board case 100, the procedure described in FIG. 19 may be reversed. That is, after releasing the engagement 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. 19(b).
By pulling out the ROM cassette 40, the ROM cassette 40 can be removed from the effect board case 100.例文帳に追加

That is, as shown in FIG. 19B, in the ROM cassette 40 in the first state, when the positioning pin 105 of the cassette mounting portion 104 is to be inserted into the insertion hole 45 of the cassette main body 40B, the substrate cover 100A The claw portion 110 interferes with the cassette case 40A in such a manner that the first fixed portion 43 of the cassette case 40A rides on the claw portion 110 of the cassette case 40A. The second fixed portion 44 also rides on the side wall portion 104 a of the cassette mounting portion 104 .

In this state, the operator cannot push down the entire ROM cassette 40 toward the effect board case 100 to connect the connector 91 of the cassette main body 40B and the connector 81 of the first effect board 55.例文帳に追加The ROM cassette 40 is in a floating state above the surface of the cassette mounting portion 104 of the substrate cover 100A.
The position of the locked portion 42 of the cassette case 40A and the position of the locked portion 109 of the board cover 100A are substantially aligned, but since the ROM cassette 40 is floating from the surface of the cassette mounting portion 104, the locked portion 42 is not locked. The portion 42 and the locked portion 109 cannot be locked.
If the operator forcibly pushes down the ROM cassette 40, the cassette case 40A may be destroyed. However, the length of the positioning pin 105 provided in the cassette mounting portion 104 is such that in the case shown in FIG. Even if the ROM cassette 40 is forcibly pushed down, stress is applied to both connectors and there is no fear of damage.
The claw part 110 functions as a restricting member that does not restrict the attachment of the ROM cassette 40 in the first state to the effect board case 100, but restricts the attachment of the ROM cassette 40 in the second state to the effect board case 100. - 特許庁do.

Conventionally, rewriting and reusing the programs and data stored in the program ROM mounted on the first effect board 50 and the data ROM mounted on the second effect board 70 required complicated work. .

In this case, there is no need to open and close the board case, and the work of directly attaching and detaching the performance ROM to and from the board is eliminated. In addition, with the configuration described above, there is little risk of applying stress to the connector extending from the performance ROM and the performance board, so there is no trouble of damaging the ROM or the performance board itself in the process of work.
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 ROMs for effects is promoted, and the manufacturing and development of game machines can be made more efficient while reducing the environmental load.

Moreover, in the present embodiment, the programs and data used in the first effect board 50 and the second effect board 70 are integrated into one integrated ROM, so that the work of removing and installing the cassette ROM is performed only once. Therefore, rewriting of the ROM for the first effect board 50 and the second effect board 70 can be completed at once.
When removing the ROM cassette 40, it is only necessary to release the locking at the fastening locking portion 450B that only has the role of fixing (locking) the ROM cassette 40 to the effect board case 100. It is not necessary to release the lock at 450B to open the effect board case 100. - 特許庁
In this embodiment, it is possible to replace the ROM in which programs and data for effect control are written with remarkably higher efficiency than in the past.

Also, conventionally, it was necessary to unfasten and open the board case just to replace the detachable parts (such as a button battery) in the effect board case.
However, in this embodiment, since the opening for accessing the button battery is provided in the cassette mounting portion, when the ROM cassette is mounted and fastened to the substrate case, the button battery cannot be accessed. Unauthorized access to the inside of the board case through the opening can be prevented. On the other hand, simply removing the ROM cassette from the cassette mounting portion exposes the opening for accessing the button battery, and the board case is closed. It will be possible to perform work such as replacing the button battery without opening the package.

Also, since the board base 100B does not have a connecting hole, the board base 100B is not locked by the caulking pin 125a. Therefore, by releasing the locking of the crimping pin 123a in the fastening sealing portion 450A and removing the fastening cover 125d of the fastening locking portion 450B, the ROM cassette 40 can be displayed without releasing the locking of the crimping pin 125a. The presentation board case 100 can be opened while attached to the 100. - 特許庁

<Method of booting production control CPU>
A method for activating the effect control CPU in this embodiment will be described. As described above, the effect control CPU 71 is obtained by integrating the image processor, the effect control CPU, and the image control CPU into one chip. You may incorporate said production control ROM and production control RAM.
Normally, such a performance control CPU was activated by a boot program (boot program) stored in a low-capacity boot ROM (boot ROM).
However, there is concern about the stable supply of low-capacity ROMs used to store boot programs these days. As for the ROM, it is necessary to check the sum value of the stored data to ensure that the data has not been rewritten and that the ROM itself has not been illegally replaced, which is complicated.
Therefore, in the present embodiment, a startup program is stored in FeRAM (Ferroelectric Random Access Memory) 300, which is a non-volatile rewritable memory, and the effect control CPU 71 is started by executing this.
Note that the FeRAM is a ferroelectric memory that is characterized by high-speed operation. It does not require a battery backup for data retention, and is known to be superior to EEPROMs and flash memories in terms of high-speed writing, high number of rewrites, and low power consumption.
By adopting FeRAM, which is a nonvolatile RAM, there is an advantage that there is no need to use a low-capacity ROM, which is of supply concern, and there is no need to check the sum value because it is a RAM.

<Write Control for FeRAM>
As described above, the FeRAM is a rewritable memory, and it is desired to use it as an area for temporarily storing game information as well as for storing the startup program.
However, if data is mistakenly written in the area storing the activation program in the FeRAM 300, the activation program is destroyed and the effect control CPU 71 cannot be activated.
Therefore, in the gaming machine of the present embodiment, data can be read from and written to a part of the area of the FeRAM 300, while the area storing the startup program of the effect control CPU 71 is read-only. is controlled so that it cannot be written.

FIG. 23 is a schematic diagram illustrating read/write control for the FeRAM of this embodiment.
In this embodiment, as shown in FIG. 23( a ), a restriction circuit 310 that restricts writing to the FeRAM 300 is provided between the effect control CPU 71 and the FeRAM 300 .
The regulation circuit 310 is a circuit that permits or regulates writing to the FeRAM 300 by switching the write enable signal inputted to the FeRAM 300 according to the designated address of the write signal to the FeRAM 300 inputted from the effect control CPU 71 .
The restriction circuit 310 has a configuration shown in detail in FIG. 23(b), and the processing by the restriction circuit 310 will be described in detail later.
As shown in FIG. 23( a ), the FeRAM 300 includes a FeRAM array 300 A composed of one or more FeRAM modules 301 and a controller 300 B that controls the FeRAM modules 301 .
From the performance control CPU 71, 19 address lines connected to the address terminals A0 to A18 of the controller 300B are connected.

From the performance control CPU 71, an address signal of 0 or 1 can be input to the address terminals A0 to A18 through each address line, and an address of 2 ¹⁹ (5242 bits) for the FeRAM module 301 can be specified. That is, the capacity of one FeRAM module 301 is 524288 bits.
In this embodiment, the FeRAM array of the FeRAM 300 includes 16 FeRAM modules 301, so the capacity of the FeRAM 300 as a whole is 2 ¹⁹ ×16=8388608 bits, ie, approximately 8 Mb.

At this time, as shown in FIG. 23(c), 2 Mb of the 8 Mb capacity is set as a read-only area 300a, and the remaining 6 Mb is set as a readable/writable area 300b.
A start program (boot program) of the effect control CPU 71 is stored in the read-only area 300a, and the game information of the gaming machine 1 is temporarily stored in the read/write area 300b.
The read-only area 300a is realized by switching the input signal to the WB terminal of the controller 300B according to the address signal designated to the FeRAM 300 (the input signal to the address terminals A0 to A18).
A part of the address signal specified by the effect control CPU 71 to the FeRAM 300, especially the upper two bits (input signals for A18 and A17) are inputted to the regulation circuit 310 . To specify the area of FeRAM 300 in units of Mbits, the information of the upper 2 bits is sufficient.

FIG. 24 is a diagram showing addresses in one FeRAM module.
As shown in FIG. 24, when the upper 2 bits (input signals to A18 and A17) of the address designated to the FeRAM 300 are 00, 2 ¹⁷ =131072 for one FeRAM module 301 by combining the input signals to the lower A16 to A0. Addresses can be specified, and 2 ¹⁷ ×16=2097152 addresses can be specified for the entire FeRAM array. That is, when the upper 2 bits of the address specified in the FeRAM 300 are 00, the address corresponding to the 2 Mb area is specified. This area is controlled to be read-only area 300a by the method described below.
When the upper 2 bits (input signals for A18 and A17) of the address specified to the FeRAM 300 are 01, 10, and 11, 2 ¹⁷ ×16=2097152 addresses are specified in the same manner as the case of 00, respectively. , 2 ¹⁷ ×16×3=6291456 addresses. The remaining 6 Mb area corresponding to these addresses becomes the readable/writable area 300b.

As shown in FIG. 23(b), the regulation circuit 310 mainly consists of two OR gates and one NOT gate.
An input signal for A18 and an input signal for A17 (both of which are 0 or 1) are input to two inputs of the first OR gate 310a.
The output obtained by inverting the output of the first OR gate 310a with the NOT gate 310b and the WR signal from the effect control CPU71 (0 indicates a write command, 1 indicates a read command) are input to the second OR gate 310c, and the output is It is input to the WB terminal of the FeRAM 300 as a write enable (WE) signal.

FIG. 25 is a diagram showing a truth table for explaining signal processing by the regulating circuit.
The processing of the regulation circuit 310 is performed as shown in FIG.
As shown in FIG. 25, when the upper two bits of the address specified for the FeRAM 300 are 00, as a result of the processing shown in FIG. . The corresponding 2 Mb area becomes the read-only area 300a.
In other words, an input signal designating 00 in the upper two bits b designates the read-only area 300 a , and in this case, the restriction circuit 310 restricts writing to the FeRAM 300 .

When the upper two bits of the address specified for the FeRAM 300 are 10, 01, and 11, as a result of the processing shown in the table above, the write enable signal, which is the output of the regulation circuit 310 at the time of writing (WR signal is 0), becomes 0, and the FeRAM 300 can be written to. The corresponding 6 Mb area becomes the readable/writable area 300b.
In other words, an input signal designating 00 in the upper two bits b designates the readable/writable area 300 b , and in this case, the regulation circuit 310 permits writing to the FeRAM 300 .

The effect control CPU 71 only inputs address signals and read/write signals to the FeRAM 300 (outputs them to the FeRAM 300) without considering the read-only area 300a and the readable/writable area 300b. Since the regulating circuit 310 permits or regulates writing to the FeRAM 300 according to the designated address, the read-only area 300a can be reliably set in the FeRAM 300. FIG. Therefore, by storing important data such as the start-up program of the effect control CPU 71 in the read-only area 300a, it is possible to prevent the important data from being overwritten and damaged.

When trying to control not to write data to a specific address of the FeRAM 300 by software processing by the performance control CPU 71, the above-mentioned accident can be prevented when an incorrect address is specified due to noise due to static electricity on the board. However, the technique of this embodiment can certainly prevent it.
In the above description, the WR signal from the effect control CPU 71 is input to the second OR gate 310c. good. In setting the read-only area 300a, it can be said that it is not always necessary to distinguish between the read command and the write command.

In addition, you may perform the starting of production|presentation control CPU71 as follows.
As shown in FIG. 3, in the gaming machine of the present embodiment, image display control for the image display device 31, sound output control for the sound output device 34, operation control for the performance accessory device 32, and lighting of the performance lighting device 33 are performed. Control and the like are configured to be collectively performed by the effect control CPU 71 .
Not limited to this, a lamp control CPU that controls the operation of the production accessory device 32 and the lighting control of the production lighting device 33 may be provided separately from the production control CPU 71 .
When the game machine 1 is started, the lamp control CPU is controlled to start earlier than the performance control CPU 71, and the lamp control CPU writes the boot program (starting program) of the performance control CPU 71 to the performance control RAM 56.例文帳に追加The effect control CPU 71 is activated by executing a boot program written in the effect control RAM 56. - 特許庁
By doing so, there is no need to provide a boot ROM for the effect control CPU 71 .

At this time, the lamp control CPU can write data into the boot program writing area in the effect control RAM 56, but the effect control CPU 71 controls so that data cannot be written.
For example, if a regulation circuit is provided to regulate reading and writing to the effect control RAM 56, and the write signal designates a specific address of the effect control RAM 56 as in the case of FeRAM (the high-order bit of the specified address is a predetermined value). case), the writing of data is regulated. As a result, the risk of overwriting and damaging the boot program on the effect control RAM 56 can be avoided. When a write signal designating a specific address is from the lamp control CPU, writing is permitted, but when it is from the effect control CPU 71, writing is controlled so as to realize the above configuration. can be done.

Next, an attachment mode of parts attached to the board cover 100A of the effect board case 100 in this embodiment will be described.
FIG. 26 is a diagram for explaining the parts attached to the effect board case, and is a diagram of the state of FIG. 12 viewed from the front side. The heatsink cover is omitted.
As shown in FIG. 26, the heat sink 500 is fixed to the effect board case 100 by screws 151 (first fixing means) from the inside (rear side) of the board cover 100A.
The board cover 100A has a screw hole 118 into which the screw 151 is screwed.
The heat sink 500 has openings 501 for the screws 151 to pass through.
The slide lock 550 is also screwed and fixed to the effect board case 100 from the inside (rear side) of the board cover 100A by screws 152 (first fixing means).
The slide lock 550 has a threaded hole 551 that engages with the screw 152 .
The board cover 100A has openings 502 for the screws 152 to pass through.

The heat sink 500 and the slide lock 550 are members that are not supposed to be removed from the effect board case 100 and replaced. Therefore, it is made impossible to remove from the outside (front side) of the effect board case 100.例文帳に追加
When the board cover 100A is screwed from the outside (front side) and the screw is released and the heat sink 500 is removed, the performance board case 100 is prevented from entering through the opening 103 (FIG. 12) of the performance board case 100. It easily leads to forgiveness. There is no point in sealing the presentation board case 100 with the fastening sealing portion 450A (FIGS. 8 and 9), and there is a concern that fraudulent acts may be carried out.
Such concerns can be resolved by screwing the heat sink 500 from the inside (rear side) of the substrate cover 100A as shown in FIG.
Alternatively, the heat sink 500 and slide lock 550 may be fitted to the effect board case 100 . For example, the heat sink 500 may be fixed with an adhesive by fitting the outer peripheral edge of the heat sink 500 into a groove provided on the inner peripheral surface of the opening 103 .

On the other hand, as shown in FIGS. 8, 12, etc., the ROM cassette 40 is a member that is supposed to be attached to and removed from the effect board case 100 for replacement. If the ROM cassette 40 is screwed from the inside (rear side) of the substrate cover 100A, the effect substrate case 100 must be opened by releasing the sealing of the fastening sealing portion 450A (FIGS. 8 and 9). , the ROM cassette 40 cannot be removed from the effect board case 100. - 特許庁
Therefore, a member such as the ROM cassette 40 that is assumed to be detachable and replaceable is attached from the outside of the effect board case 100, and is attached to the fastening sealing portion 450B (FIGS. 8 and 9), which is a second fixing means different from screws. is fixed from the outside (front side) of the substrate cover 100A.

Next, a manner of removing static electricity from the surface of the effect board in this embodiment will be described.
FIG. 27 is a partially enlarged view of the first effect board housed in the board base, viewed from the front side.
FIG. 28 is a partially enlarged view seen from the rear surface side of the board base housing the first effect board.
FIG. 29 is a partially enlarged view of the first effect board viewed from the rear side.
In order to ground the static electricity generated in the image display device (liquid crystal screen) installed on the front side of the presentation board case 100, a metal plate (grounding plate) 88 is provided on the front side of the presentation board case 100 (board base 100B). (Fig. 28).
As shown in FIG. 27 , a ground wire 87 extends from a metal plate (ground plate) 88 and is connected to a connector 84 on the first effect board 55 .
Static electricity generated in the image display device and the like is collected in the first effect board 55 through the ground plate 88 and the ground wire 87, and grounded through a cable connected to a connector (not shown).

Furthermore, in this embodiment, the effect board case 100 that houses the effect control board 95 (the first effect board 55 and the second effect board 70) is made of a conductive carbon material.
As shown in FIG. 27, an electrical contact 143 made of a conductive material such as a metal plate such as a copper plate is provided around an opening 142 on the front side of the first effect board 55 through which the screw 141 is passed. The screw 141 is made of a conductive material, such as a conductive metal.
Also, as shown in FIG. 29, an electrical contact 144 made of a conductive material such as a metal plate such as a copper plate is provided around the opening 142 through which the screw 141 is passed on the rear side of the first effect board 55 .
The first effect board 55 is installed in the effect board case 100, and the first effect board 55 is screwed into the effect board case 100 through the screw 141 through the opening 142.例文帳に追加
The board cover 100A has a screw hole 144 (FIGS. 11 and 26) into which the screw 141 is screwed.

The static electricity generated in the image display device (liquid crystal screen) not only flows from the ground plate 88 to the ground wire 87, but also flows to the presentation substrate case 100 formed of a conductive carbon material and accumulated (charged). To go.
Then, the static electricity charged in the effect board case 100 flows to the surface of the first effect board 55 through the screw holes 144 of the effect board case 100 formed of carbon material, the conductive screws 141, and the electrical contacts 144. It is earthed (grounded) through a cable connected to a connector (not shown). By accumulating static electricity in the effect board case 100 and then grounding it, static electricity generated in an image display device (liquid crystal screen) or the like can be securely grounded.
Instead of the screw 141, the first effect board 55 may be fixed in the effect board case 100 by a pin made of a conductive material such as a conductive metal. In that case, the pin is passed through the opening 142 and fixed by a pin receiver provided on the substrate cover 100A.
Also, the first effect board 55 may be fixed in the effect board case 100 with a conductive adhesive. At that time, the adhesive is applied so as to contact the electrical contacts on the first rendering board 55 .
By providing a conductive pin or an adhesive between the electrical contact on the first effect board 55 and the effect board case 100 made of a conductive material, the same effect as using the conductive screw 141 can be obtained. .

FIG. 30 shows a modification of the configuration of FIG. 15, in which the ROM cassette 40 containing the integrated ROM board 90 is also made of a conductive carbon material.
In the integrated ROM board 90, an electrical contact 94 made of a conductive material such as a metal plate such as a copper plate is provided around an opening 93 through which a screw 95 is passed to fix the integrated ROM board 90 to the cassette main body 40B. Screw 95 is formed from a conductive material, such as a conductive metal.
The integrated ROM board 90 is installed in the cassette main body 40B, and screws 95 are passed through the openings 93 to screw the integrated ROM board 90 into the cassette case (cassette main body 40B).
At this time, the screw 95 is screwed into the screw hole 49 of the cassette main body 40B.
The static electricity charged in the effect board case 100 passes through the cassette body 40B made of carbon material, the screw holes 49, the conductive screws 95, and the copper plate (electric contact) 94, and charges the integrated ROM board 90. Static electricity also flows through the cassette case 40A, and the entire ROM cassette 40 is charged.
The static electricity charged in the ROM cassette 40 flows to the surface of the first effect board 55 through the effect board case 100, the screw hole 144 of the effect board case 100, the conductive screw 141, and the electrical contact 144, and to the connector (not shown). Grounded through attached cable.
By accumulating static electricity not only in the performance board case 100 but also in the ROM cassette 40 and then grounding, the static electricity generated in the image display device (liquid crystal screen) or the like can be reliably grounded.
Also, instead of the screw 95, the integrated ROM board 90 may be fixed to the cassette main body 40B by a pin made of a conductive material such as a conductive metal. In that case, the pin is passed through the opening 93 and fixed by a pin receiver provided in the cassette main body 40B.
Alternatively, the integrated ROM board 90 may be fixed to the cassette main body 40B with a conductive adhesive. The adhesive is then applied to contact the electrical contacts on the integrated ROM board 90 .
By providing conductive pins or adhesive between the electrical contacts on the integrated ROM board 90 and the cassette case made of conductive material, the same effect as using the conductive screws 95 can be obtained.

FIG. 31 is a diagram showing the effect board case in which the harness is attached to the connector of the first effect control board.
In the amusement arcade, when the game machine is maintained or cleaned, a heat sink and a ROM cassette are attached in the effect board case 100, and each effect control unit incorporating the effect control board 95 is removed from the main control board 50.例文帳に追加Even when the content of the performance is changed, each performance control unit is exchanged with the manufacturer side.
A harness 700 having one end connected to the connector 83 of the effect control board 95 extends from the opening 116 ( FIG. 10 ) of the effect board case 100 . This other end extends to the main control board 50 .
When the harness 700 is removed from the performance control board 95 and further removed from the main control board 50, it becomes unclear which side of the harness 700 should be attached to the connector 83.例文帳に追加Also, from the viewpoint of reuse, it is not desirable to frequently insert and remove the harness from the connector 83 of the effect control board 95 .
It is desirable to handle the performance board unit (performance control board 95) with the harness 700 attached. Therefore, in this embodiment, a connector cover 86 is provided near the opening 116 of the effect board case 100 so that the operator does not remove the harness from the connector 83 from the first effect board 55, and a similar connector cover is provided for the main control. It is not provided on the substrate 50 side.
To connect the harness 700 to the connector 83 , the lid of the connector cover 86 is opened and the connector of the harness 700 is inserted through the opening 116 . With the presence of the connector cover 86, the operator can be urged to remove the harness 700 from the side of the main control board 50 without the connector cover instead of removing it from the performance board unit (performance control board 95).
