The normal figure holding area 213 includes a first area 218a, a second area 218b, a third area 218c, and a fourth area 218d, and numerical information of the normal electric random number counter C4 according to the winning history to the through gate 35. Is stored in any of the areas 218a to 218d as the reserved information on the normal drawing side.

In this case, in the first area 218a to the fourth area 218d, when the through gate 35 is awarded a plurality of times in succession, the first area 218a → the second area 218b → the third area 218c → the fourth area. Numerical information is stored in chronological order in the order of 218d. By providing the four areas 218a to 218d in this way, up to four winning histories of the game balls to the through gate 35 can be reserved and stored.

The number of items that can be stored in the holding area 213 is not limited to four, and may be any number of items, such as two, three, or five or more, and may be a single number. It may be.

An execution area 219 for a normal map is provided in the normal map reservation area 213. The execution area 219 for the normal map is an area in which the hold information for which the hit / fail determination for support is to be determined is stored when the variable display is started on the normal map display unit 38a. Specifically, when the variable display of the normal map display unit 38a is started, the hold information stored in the first area 218a of the normal map hold area 213 is moved to the execution area 219 for the normal map.

Each of the above counters will be described in detail.

First, the Fuden random number counter C4 will be described. The normal electric random number counter C4 has a configuration in which, for example, 1 is added in order within the range of 0 to 250, and after reaching the maximum value, it returns to 0. The normal electric random number counter C4 is periodically updated, and is stored in the normal figure holding area 213 of the main RAM 66 at the timing when the game ball wins the through gate 35. Then, at a predetermined timing, a lottery is performed as to whether or not to control the general electric accessory 34a to the open state according to the value of the stored general electric random number counter C4.

In the pachinko machine 10, a plurality of types of support modes are set so that the modes of support by the general electric accessory 34a are different from each other. Specifically, in the support mode, when the game ball is continuously launched to the game area PA in the same manner, the general electric accessory 34a of the second operating port 34 is per unit time. A high-frequency support mode and a low-frequency support mode are set so that the frequency of being opened is relatively high or low.

In the high frequency support mode and the low frequency support mode, the probability of winning the normal power open state in the normal power open lottery using the normal power random number counter C4 is the same (for example, both are 4/5), but it is high. In the frequency support mode, the number of times the normal electric accessory 34a is opened when the general electric power open state is won is set more than in the low frequency support mode, and one open time is set longer. There is. In this case, in the high-frequency support mode, when the general electric power open state is won and the general electric accessory 34a is opened multiple times, from the end of one open state to the start of the next open state. The closing time is set shorter than the one-time opening time. Furthermore, in the high-frequency support mode, compared to the low-frequency support mode, the minimum secured time is secured for the next public power opening lottery after one public power opening lottery is performed (that is, the general drawing). The duration of one display on the display unit 38a) is set short.

As described above, in the high frequency support mode, the probability that the second operating port 34 is won is higher than in the low frequency support mode. In other words, in the low frequency support mode, the probability of winning the first operating port 33 is higher than that of the second operating port 34, but in the high frequency support mode, the second operation is higher than the first operating port 33. The probability that a prize will be given to the mouth 34 increases.

The configuration for increasing the frequency with which the high-frequency support mode is opened to the public power per unit time is higher than that of the low-frequency support mode. It may be configured to increase the probability of winning the open state. In addition, the reserved time secured for the next public electric opening lottery after one public electric opening lottery is performed (for example, is executed on the general drawing display unit 38a based on the winning of the through gate 35). In a configuration in which multiple types of variable display times are prepared, the high-frequency support mode is set so that a shorter reservation time is easier to select or the average reservation time is shorter than the low-frequency support mode. May be good. Furthermore, the number of times of opening is increased, the opening time is lengthened, and the securing time secured when one public power opening lottery is held and then the next public power opening lottery is held is shortened. By applying any one of the conditions or any combination of the conditions of shortening the average time and increasing the winning probability, the advantage of the high frequency support mode over the low frequency support mode may be enhanced.

When the general electric power open state is won in the general electric power open lottery using the general electric power random number counter C4, the general electric power open state is set. The open state of the general electric power is terminated when the public electric accessory 34a is opened and closed a predetermined number of times, or when a predetermined maximum number of game balls win a prize in the second operating port 34. To do. Specifically, the upper limit is 10 in both the low-frequency support mode and the high-frequency support mode. On the other hand, the number of times of opening and closing of the utility object 34a is one in the low-frequency support mode, whereas it is more than one in the high-frequency support mode, which is more specific than in the low-frequency support mode. It is 3 times. Further, the duration of one opening of the general electric accessory 34a is 1 second in the low frequency support mode, whereas it is 2 seconds in the high frequency support mode.

Next, the hit random number counter C1 will be described. The hit random number counter C1 has a configuration in which, for example, 1 is added in order within the range of 0 to 599, and after reaching the maximum value, it returns to 0. In particular, when the hit random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the hit random number counter C1. The random number initial value counter CINI is a loop counter similar to the hit random number counter C1 (value = 0 to 599). The winning random number counter C1 is periodically updated, and when the game ball wins the first operating port 33, it is stored in the first special figure holding area 215 of the special figure holding area 212, and the game ball is stored in the second operating port 34. It is stored in the second special figure holding area 216 of the special figure holding area 212 at the timing of winning a prize. Then, the winning / failing determination is performed using the value of the stored hit random number counter C1.

The value of the random number that is won in the winning / failing determination is stored in the main ROM 65 as a winning / failing table. In the hit / fail table, a big hit result, a small hit result, and a miss result are set as the hit / miss result. The jackpot result is a win / fail result that can trigger a shift to the open / close execution mode in which the special electric winning device 32 is controlled to open / close, and can also trigger a shift to at least one of the win / fail lottery mode and the support mode. The small hit result is a win / fail result that does not trigger a shift in both the win / fail lottery mode and the support mode, while it triggers the transition to the open / close execution mode in which the special electric winning device 32 is controlled to open / close. The deviation result is a success / failure result that does not trigger a transition to the open / close execution mode, and also does not trigger a transition to the win / fail lottery mode and the support mode.

As the pass / fail table, there are a pass / fail table for the low probability mode and a pass / fail table for the high probability mode. That is, in the pachinko machine 10, the same pass / fail table is referred to in the hold information acquired based on the winning of the first operating port 33 and the holding information acquired based on the winning of the second operating port 34. In any case, there are a low-probability mode and a high-probability mode as lottery modes in the winning / losing lottery.

To explain each hit / fail table in detail, the hit / fail table for the low probability mode has two random number values (for example, "5" and "305") that result in a big hit, and the random number values that result in a small hit. Is three (for example, "55", "355", "555"). Other than that, it is a random number value that results in a deviation.

In the hit / fail table for the high probability mode, the number of random numbers that result in big hits is set to be larger than that in the case of the hit / miss table for the low probability mode for the first special figure, and specifically, it is 20. (For example, "5", "34", "65", "130", "163", "192", "220", "245", "276", "305", "334", "365", "392", "420", "470", "495", "520", "558", "575", "599"). In this case, the value group of the winning random number counter C1 that wins the jackpot in the low probability mode is included in the value group of the winning random number counter C1 that wins the jackpot in the high probability mode. On the other hand, the value of the random number that is the result of the small hit is the same as in the case of the hit / fail table for the low probability mode.

If the probability of a jackpot result is higher in the high probability mode than in the low probability mode, the number and value of the random numbers to be won are arbitrary, and in the situation of the low probability mode, the jackpot result is obtained. The value group of the winning random number counter C1 may or may not be included in the value group of the winning random number counter C1 which is a big hit in the high probability mode. ..

Next, the jackpot type counter C2 will be described. The jackpot type counter C2 is configured to be incremented by 1 in order within the range of 0 to 99, reach the maximum value, and then return to 0. The jackpot type counter C2 is periodically updated, and when the game ball wins the first operating port 33, it is stored in the first special figure holding area 215 of the special figure holding area 212, and the game ball is stored in the second operating port 34. It is stored in the second special figure holding area 216 of the special figure holding area 212 at the timing of winning a prize. Then, the distribution determination is performed using the value of the stored jackpot type counter C2.

Here, a plurality of types of jackpot results are set in the pachinko machine 10, and each of these jackpot results includes (1) the contents of the opening / closing execution mode, (2) the contents of the winning / failing lottery mode after the opening / closing execution mode ends, and ( 3) At least one of the three contents, that is, the contents of the support mode after the end of the open / close execution mode, is different.

The open / close execution mode executed when the jackpot is won is the round number regulation mode as described above. In the round number regulation mode, the high-frequency winning mode and the low-frequency winning mode are set so that the frequency of winning the special electric winning device 32 from the start to the end of the opening / closing execution mode is relatively high or low. And are set. Specifically, in the pachinko machine 10, a plurality of types of one-time opening mode of the special electric winning device 32 are set with different opening durations from the opening to the closing of the special electric winning device 32. There is. Specifically, a long-time mode in which the opening duration is set to 29 seconds, which is a long time, and a short-time mode in which the opening duration is set to 0.05 seconds, which is shorter than the long time, are described. It is set. In the pachinko machine 10, when the launch operation device 28 is operated by the player, the game ball launch mechanism 27 is driven so that one game ball is launched toward the game area PA every 0.6 seconds. Be controlled. In addition, the maximum number of end conditions for round games is set to 10. Then, in the long-time mode of the above-mentioned opening modes, the opening duration is set to be longer than the product of the firing cycle of the game balls and the upper limit number of one round game. On the other hand, in the short-time mode, the opening duration is set to be shorter than the product of the firing cycle of the game ball and the upper limit number of one round game, and more specifically, the opening duration is shorter than the firing cycle of the game ball. ing. Therefore, when the special electric winning device 32 is opened once in a long-time mode, it is expected that the special electric winning device 32 will be awarded the maximum number of prizes in one round game, and the time is short. When the special electric winning device 32 is opened once in the embodiment, it is expected that the special electric winning device 32 will not be won.

In the high-frequency winning mode, the special electric winning device 32 is opened once in each round game in a long-time mode. On the other hand, in the low-frequency winning mode, the special electric winning device 32 is opened once in each round game in a short-time mode.

The number of times the special electric winning device 32 is opened and closed in the high-frequency winning mode and the low-frequency winning mode, the number of round games, the opening duration for one opening, and the upper limit number in one round game are those in the high-frequency winning mode. Is not limited to the above values and is arbitrary as long as the frequency of winning the special electric winning device 32 from the start to the end of the opening / closing execution mode is higher than that of the low frequency winning mode. Is.

The opening / closing execution mode executed when a small hit is won is the opening / closing number regulation mode as described above. In the open / close number regulation mode, the special electric winning device 32 is opened five times in a short time mode. In this case, the upper limit of the end condition of the open / close number specified mode is set to 10, and the total opening duration of the open / close number specified mode is the maximum number of the game ball firing cycle and the open / closed number specified mode. It is set to a time shorter than the product. Therefore, in the open / close number specified mode, the round game is not executed, and whether or not the number of winnings is the upper limit is determined by the total number of winnings in the opening / closing number specified mode. The probability that the opening and closing of will be executed increases.

The distribution destination of the type of the jackpot result with respect to the jackpot type counter C2 is stored in the main ROM 65 as a distribution table. The contents of the distribution table will be described with reference to FIGS. 25 (a) and 25 (b).

Further, after the end of the open / close execution mode, the low-frequency support mode is set regardless of the support mode before the shift to the open / close execution mode. This low-frequency support mode will result in a big hit next time, and will continue at least until it shifts to the open / close execution mode.

In the 4R high-accuracy jackpot result, the open / close execution mode is a high-frequency winning mode in which four round games occur. In this open / close execution mode, 260 game balls can be expected to be paid out. In addition, after the opening / closing execution mode ends, the high probability mode is set regardless of the winning / failing lottery mode before the opening / closing execution mode shift. This high-probability mode will at least continue until the next jackpot result and the resulting open / close execution mode. Further, after the end of the open / close execution mode, the high-frequency support mode is set regardless of the support mode before the shift to the open / close execution mode. This high frequency support mode will at least continue until the next big hit result and the resulting open / close execution mode.

In the 5R high-accuracy jackpot result, the open / close execution mode is a low-frequency winning mode in which five round games occur. In this open / close execution mode, the special electric winning device 32 cannot be expected to win a prize, so that the number of game balls to be paid out is substantially zero. In addition, after the opening / closing execution mode ends, the high probability mode is set regardless of the winning / failing lottery mode before the opening / closing execution mode shift. This high-probability mode will at least continue until the next jackpot result and the resulting open / close execution mode. Further, the support mode becomes the high frequency support mode if the mode before the shift to the open / close execution mode is the high frequency support mode, while it becomes the low frequency support mode if the mode before the shift to the open / close execution mode is the low frequency support mode. These support modes will at least continue until the next big hit result and the resulting open / close execution mode.

In this open / close execution mode, 520 game balls can be expected to be paid out. In addition, after the opening / closing execution mode ends, the high probability mode is set regardless of the winning / failing lottery mode before the opening / closing execution mode shift. This high-probability mode will at least continue until the next jackpot result and the resulting open / close execution mode. Further, after the end of the open / close execution mode, the high-frequency support mode is set regardless of the support mode before the shift to the open / close execution mode. This high frequency support mode will at least continue until the next big hit result and the resulting open / close execution mode.

As the distribution table, as shown in FIGS. 25 (a) and 25 (b), the distribution for the first special figure used in the distribution determination of the reserved information acquired based on the winning of the first operating port 33. A minute table and a distribution table for the second special figure used for determining the distribution of the reserved information acquired based on the winning of the second operating port 34 are set.

Explaining each distribution table in detail, as shown in FIG. 25 (a), the distribution table for the first special figure has 12R low accuracy jackpot results and 12R low probability jackpot results as the types of jackpot results to be sorted. A 5R high-accuracy jackpot result, a 12R high-accuracy jackpot result A, a 12R high-accuracy jackpot result B, and a 16R high-accuracy jackpot result are set. In the distribution table for the first special figure, "0 to 19" corresponds to the 12R low accuracy jackpot result, "20 to 39" corresponds to the 5R high accuracy jackpot result, and "40 to 68". Corresponds to the 12R high-accuracy jackpot result A, "69-88" corresponds to the 12R high-accuracy jackpot result B, and "89-99" corresponds to the 16R high-accuracy jackpot result. In the case of the distribution table for the first special figure, if the jackpot is won, the probability of a 12R low probability jackpot result is 20%, the probability of a 5R high probability jackpot result is 20%, and 12R. The probability of a high-accuracy jackpot result A is 29%, the probability of a 12R high-accuracy jackpot result B is 20%, and the probability of a 16R high-accuracy jackpot result is 11%.

Here, when a small hit result is obtained, in the opening / closing execution mode triggered by the small hit result, the special electric winning device 32 is opened / closed five times in a short-time mode. On the other hand, in the 5R high-accuracy jackpot result, the mode shifts to the round number-specified mode in which the round game is performed up to 5 times, and in each round game, the special electric winning device 32 is opened and closed once in a short time mode. That is, when either the 5R high-accuracy big hit result or the small hit result is obtained, the operation mode of the special electric winning device 32 in the open / close execution mode is apparently the same. Further, in the game times when these game results are obtained, although the stop results different from each other are displayed on the first special figure display unit 37a, the display area is set larger than that of the first special figure display unit 37a. In the symbol display device 41, the stop result is displayed in an indistinguishable manner. Specifically, in any of the above game results, the symbol display device 41 stops and displays a common symbol combination (for example, "3.4.1") on any of the effective lines. In addition, when a 5R high-probability jackpot result is obtained in the low-frequency support mode, the opening / closing execution mode when a small hit result is obtained based on a prize in the first operating port 33 during the opening / closing execution mode triggered by the result. The effect is executed in a manner indistinguishable from the above, and after the opening / closing execution mode is completed, the effect indicating that the mode is in the high probability mode is not executed in the symbol display device 41 or the like, and the effect is sent to the first operating port 33. When a small hit result is obtained based on a prize, the effect is executed in the same manner as after the open / close execution mode. With the above configuration, for example, in the situation of the low probability mode and the low frequency support mode, when the open / close execution mode that becomes the low frequency winning mode or the open / close execution mode that becomes the open / close number specified mode occurs, the player , The game will be played while expecting that the mode will shift to the high probability mode after the opening / closing execution mode is completed, and the interest of the game will be improved.

In addition, if a 12R low-accuracy jackpot result or a 12R high-accuracy jackpot result B is obtained based on the winning of the first operating port 33, the mode shifts to the round number regulation mode in which the round game is performed up to 12 times, and each round. In the game, the special electric winning device 32 is opened and closed once according to the long-time mode. That is, when either the 12R low-accuracy jackpot result or the 12R high-accuracy jackpot result B is obtained, the operation mode of the special electric winning device 32 in the open / close execution mode is apparently the same. Further, in the game times when these game results are obtained, although the stop results different from each other are displayed on the first special figure display unit 37a, the display area is set larger than that of the first special figure display unit 37a. In the symbol display device 41, the stop result is displayed in an indistinguishable manner. Specifically, in any of the above game results, the symbol display device 41 stops and displays the same even-numbered symbol combination on any of the effective lines. In addition, when the 12R high probability jackpot result B is obtained in the low frequency support mode, the opening / closing execution mode triggered by the 12R high probability jackpot result is indistinguishable from the opening / closing execution mode when the 12R low probability jackpot result is obtained. After the opening / closing execution mode is executed, the effect indicating that the symbol display device 41 or the like is in the high probability mode is not executed after the opening / closing execution mode is completed, and the 12R low probability jackpot result is obtained. The effect is executed in the same manner as in. With the above configuration, for example, in a situation of a low probability mode and a low frequency support mode, when an open / close execution mode in which 12 round games are executed occurs, the player can perform the open / close execution mode after the end of the open / close execution mode. The game will be played while expecting that the mode has shifted to the high probability mode, and the interest of the game will be improved.

On the other hand, in the distribution table for the second special figure, as shown in FIG. 25 (b), the types of jackpot results to be sorted are 8R low accuracy jackpot result, 4R high accuracy jackpot result, and 8R high. The probability jackpot result and the 16R high accuracy jackpot result are set. In the distribution table for the second special figure, "0 to 19" corresponds to the 8R low accuracy jackpot result, "20 to 31" corresponds to the 4R high accuracy jackpot result, and "32 to 55". Corresponds to the 8R high-accuracy jackpot result, and "56-99" corresponds to the 16R high-accuracy jackpot result. In the case of the distribution table for the second special figure, if the jackpot is won, the probability of getting an 8R low probability jackpot result is 20%, the probability of getting a 4R high probability jackpot result is 12%, and 8R. The probability of a high-accuracy jackpot result is 24%, and the probability of a 16R high-accuracy jackpot result is 44%.

Here, if an 8R low-accuracy jackpot result or an 8R high-accuracy jackpot result is obtained based on the winning of the second operating port 34, the game shifts to the round number regulation mode in which the round game is performed up to 8 times, and each round. In the game, the special electric winning device 32 is opened and closed once according to the long-time mode. That is, when either the 8R low-accuracy jackpot result or the 8R high-accuracy jackpot result is obtained, the operation mode of the special electric winning device 32 in the open / close execution mode is apparently the same. Further, in the game times when these game results are obtained, although the stop results different from each other are displayed on the first special figure display unit 37a, the display area is set larger than that of the first special figure display unit 37a. In the symbol display device 41, the stop result is displayed in an indistinguishable manner. Specifically, in any of the above game results, the symbol display device 41 stops and displays the same even-numbered symbol combination on any of the effective lines. In addition, in both the case where the 8R low probability jackpot result is obtained and the case where the 8R high probability jackpot result is obtained, it is not possible to distinguish which jackpot result is in the opening / closing execution mode triggered by the result. After the opening / closing execution mode is completed, the effect indicating that the symbol display device 41 or the like is in the high probability mode is not executed, and the effect is executed in the same manner. Immediately after the open / close execution mode, the support mode becomes the high-frequency support mode in any case. With the above configuration, for example, in a situation of a high probability mode and a high frequency support mode, when an open / close execution mode in which eight round games are executed occurs, the player can perform the open / close execution mode after the end of the open / close execution mode. The game will be played while expecting that the transition to the low probability mode has not occurred, and the interest of the game will be improved.

Further, the distribution table for the first special figure and the distribution table for the second special figure have the same probability of becoming the high probability mode after the open / close execution mode when the jackpot is won. On the other hand, the probability of becoming the high-frequency winning mode in the open / close execution mode is higher in the distribution table for the second special figure than in the distribution table for the first special figure. More specifically, the distribution table for the first special figure can be in the low frequency winning mode, whereas the distribution table for the second special drawing cannot be in the low frequency winning mode. Furthermore, in the distribution table for the first special figure, the probability of achieving the most advantageous jackpot result, 16R high accuracy jackpot result, is 11%, which is the lowest distribution probability compared to other jackpot results. On the other hand, in the distribution table for the second special figure, the probability of achieving the 16R high-accuracy jackpot result, which is the most advantageous jackpot result, is 44%, which is the highest distribution probability as compared with other jackpot results. Therefore, as a type of jackpot result that can be selected when a jackpot is won, a prize is generated in the second operating port 34 as compared with a case where a prize is generated in the first operating port 33 and an internal lottery is performed. It is more advantageous for the player when the internal lottery is performed.

Next, the reach random number counter C3 will be described. The reach random number counter C3 has a configuration in which, for example, 1 is added in order within the range of 0 to 238, and after reaching the maximum value, it returns to 0. Here, in the pachinko machine 10, an expected effect is set as a kind of display effect in the symbol display device 41. The expected effect is a symbol display device 41 that is provided with a symbol display device 41 capable of displaying variable symbols, and in a game machine in which a final stop result is given as a result of a game that results in a predetermined jackpot. This is a display state for making the player think that it is a variable display state in which the stop result is derived and displayed after the start of the variable display of the symbol in the above. Specifically, regarding the grant correspondence result, the combination of symbols with the same number on any of the effective lines is stopped and displayed.

Two types of expected effects are set: a reach display and a notice display for expecting the occurrence of the reach display and the occurrence of the grant response result in the stage before the reach display occurs.

In the reach display, a combination of reach symbols is displayed by stopping and displaying a part of the symbol rows among the plurality of symbol rows displayed on the display surface 41a of the symbol display device 41, and the remaining symbol rows are displayed in that state. A display state in which a variable display of a symbol is performed in a symbol string is included. In addition, in the state where the combination of reach symbols is displayed as described above, the remaining symbol rows are displayed in a variable manner, and a predetermined character or the like is displayed as a moving image on the background screen to produce a reach effect. , A combination of reach symbols is reduced or hidden, and then a predetermined character or the like is displayed as a moving image on substantially the entire display surface 41a to perform a reach effect.

In the notice display, after the variable display of the symbol is started on the display surface 41a of the symbol display device 41, the symbol is variablely displayed in all the symbol rows Z1 to Z3, or in some symbol rows. In the situation where the symbols are displayed in a variable manner in a plurality of symbol rows, a mode in which the character is displayed separately from the symbols on the symbol rows Z1 to Z3 is included. In addition, the background screen has a predetermined mode different from the previous mode, and the symbols on the symbol rows Z1 to Z3 have a predetermined mode different from the previous mode. Such a notice display may occur in any of the game times when the reach display is performed and when the reach display is not performed, but the case where the reach display is performed is higher than the case where the reach display is not performed. It is set to occur with probability.

The reach display is executed regardless of the value of the reach random number counter C3 in the game times when the combination of the same symbols is finally stopped and displayed. Further, in the big hit result in which the combination of the same symbols is not stopped and displayed, or in the game times corresponding to the small hit result, the game is not executed regardless of the value of the reach random number counter C3. Further, in the game times corresponding to the deviation result, the reach random number counter C3 acquired at a predetermined timing by referring to the reach table stored in the reach table storage area of the main ROM 65 corresponds to the occurrence of the reach display. If so, it will be executed.

On the other hand, the determination as to whether or not to display the advance notice is performed not by the main CPU 64 but by the voice emission control device 70. In this case, in the voice emission control device 70, the game times corresponding to either the big hit result or the small hit result are more likely to generate the notice display and the appearance rate is higher than the game times corresponding to the missed result. The lottery process for the notice display is executed so as to satisfy at least one of the conditions that the low notice display is likely to occur. By the way, this lottery result is reflected when the effect for the game round is executed on the symbol display device 41.

Next, the variable type counter CS will be described. The variation type counter CS has a configuration in which, for example, 1 is added in order within the range of 0 to 198, and after reaching the maximum value, it returns to 0. The variation type counter CS is used in the main CPU 64 to determine the display duration on the first special symbol display unit 37a or the second special symbol display unit 37b and the symbol display duration on the symbol display device 41. Specifically, the value of the fluctuation type counter CS is used when determining the fluctuation pattern at the start of the fluctuation display on the first special symbol display unit 37a or the second special symbol display unit 37b and at the start of the fluctuation of the symbol by the symbol display device 41. To be acquired.

<About the processing configuration of the main CPU 64>
Next, each process executed to advance the game on the main CPU 64 will be described. The processing of the main CPU 64 is roughly divided into a main processing that is started when the power is turned on and a timer interrupt processing that is started periodically (in this embodiment, at a cycle of 4 milliseconds).

<Main processing>
First, the main process will be described with reference to the flowchart of FIG.

In step S101, the power-on wait process is executed. In the power-on wait process, for example, the process waits for one second after the main process is started without proceeding to the next process. In the following step S102, access to the main RAM 66 is permitted, and in step S103, the internal function register of the main CPU 64 is set.

After that, in step S104, it is determined whether or not the RAM erase switch is manually operated. As described above, the RAM erasure switch is provided in the power supply / emission control device 78, and when the RAM data is initialized at the time of power-on, the power is turned on while pressing the RAM erasure switch. In the following step S105, it is determined whether or not "1" is set in the power failure flag of the main RAM 66. Further, in step S106, a checksum calculation process for calculating a checksum is executed, and in the following step S107, whether or not the checksum matches the checksum saved when the power is turned off, that is, the validity of the stored data is determined. judge.

When the RAM erase switch is pressed (step S104: YES), the process proceeds to step S108. Further, when the power cutoff occurrence information is not set (step S105: NO) or when an abnormality of the data stored and retained by the checksum is confirmed (step S107: NO), the process of step S108 is performed in the same manner. Transition. In step S108, the main RAM 66 is cleared as the initialization of the main RAM 66. Then, the process proceeds to step S109.

On the other hand, when the RAM erase switch is not pressed (step S104: NO), the power failure flag is set to "1" (step S105: YES), and the checksum is normal (step S107). : YES), the process proceeds to step S109 without executing the process of step S108. In step S109, the power-on setting process is executed. In the power-on setting process, a predetermined area of the main RAM 66 such as initialization of the power failure flag is set as an initial value, and a command corresponding to the current gaming state is issued to the voice emission control device 70 in order to recognize the current gaming state. Send to.

After that, the process proceeds to the residual processing of steps S110 to S113. That is, although the main CPU 64 is configured to periodically execute the timer interrupt processing, a residual time is generated between the timer interrupt processing of 1 and the next timer interrupt processing. This residual time varies depending on the processing completion time of each timer interrupt process, and the residual process of steps S110 to S113 is repeatedly executed by utilizing the irregular time. In this respect, it can be said that the residual processing in steps S110 to S113 is an irregular process that is executed irregularly.

In the residual processing, first, in step S110, interrupt prohibition is set in order to prohibit the occurrence of timer interrupt processing. In the following step S111, the random number initial value update process for updating the random number initial value counter CINI is executed, and in step S112, the variation counter update process for updating the variation type counter CS is executed. In these update processes, the current numerical information is read from the corresponding counter of the main RAM 66, a process of adding 1 to the read numerical information is executed, and then a process of overwriting the read source counter is executed. In this case, when the counter value reaches the maximum value, it is cleared to "0" respectively. After that, in step S113, the interrupt enable setting for switching from the state in which the occurrence of the timer interrupt process is prohibited to the state in which the occurrence of the timer interrupt process is permitted is set. After executing the process of step S113, the process returns to step S110, and the process of steps S110 to S113 is repeated.

<Timer interrupt processing>
Next, the timer interrupt process will be described with reference to the flowchart of FIG. 27. Timer interrupt processing is executed periodically (for example, in a cycle of 4 milliseconds).

In the timer interrupt process, first, the power failure information storage process is executed in step S201. In the power failure information storage process, it is monitored whether or not a power failure signal corresponding to the occurrence of power failure is received from the power failure monitoring circuit 201, and if the occurrence of a power failure is identified, the power failure processing is executed. In the power failure processing, the payout reset signal output from the main CPU 64 to the payout side CPU 222 is lowered from the HI state to the LOW state. As described above, the payout side CPU 222 executes a process for initializing the payout side RAM 224 when the fall of the payout reset signal is detected.

In the following step S202, the lottery random number update process is executed. In the lottery random number update process, the hit random number counter C1, the jackpot type counter C2, the reach random number counter C3, and the general electric random number counter C4 are updated. Specifically, after executing a process of sequentially reading the current numerical information from the hit random number counter C1, the jackpot type counter C2, the reach random number counter C3, and the general electric random number counter C4, and adding 1 to each of the read numerical information. Executes the process of overwriting the read source counter. In this case, when the counter value reaches the maximum value, it is cleared to "0" respectively.

After that, in step S203, the random number initial value update process is executed in the same manner as in step S111, and in step S204, the fluctuation counter update process is executed in the same manner as in step S112.

In the following step S205, a fraud detection process for monitoring whether or not a fraudulent radio wave detection and a fraudulent magnetism detection set as a monitoring target for fraud have occurred is executed. As described above with reference to FIG. 21, the radio wave detection sensor 202 and the magnetic detection sensor 203 are connected to the input side of the MPU 63 via the second relay board PB2 and the fourth connector CN4. In the fraud detection process in step S205, the main CPU 64 monitors whether or not fraud to be monitored has occurred based on the state of the detection signal received from the radio wave detection sensor 202 and the detection signal received from the magnetic detection sensor 203. To do. As described above, the main CPU 64 identifies that an illegal radio wave is detected when the detection signal received from the radio wave detection sensor 202 rises from the LOW state to the HI state, and the magnetic detection sensor 203. It is specified that an illegal magnetism is detected when the rise of the detection signal received from the LOW state to the HI state is detected. In the fraud detection process in step S205, when it is specified that any fraud has occurred, a fraud detection notification command is transmitted to the voice emission control device 70. When the voice emission control device 70 receives the fraud detection notification command, the voice emission control device 70 controls the sound output of the speaker unit 54 and controls the display control device 90 so that the fraud detection notification is performed. As a result, the speaker unit 54 and the symbol display device 41 are notified that the monitoring target has been fraudulent. After that, "1" is set in the game stop flag provided in the main RAM 66. As a result, the processes for advancing the game (processes in steps S208 to S219) are not executed.

After that, the Tokuden Fuden monitoring process is executed (step S206). In the special electric power monitoring process, when the open / close execution mode is not set, it is determined whether or not the special electric power winning device 32 is in the open state based on the state of the detection signal received from the special electric power opening detection sensor 32b. Then, when it is specified that the special electric winning device 32 is in the open state, a special electric abnormality notification command is transmitted to the voice emission control device 70. When the voice emission control device 70 receives the special electric abnormality notification command, the voice emission control device 70 controls the sound output of the speaker unit 54 and controls the display control device 90 so that the special electric abnormality notification is performed. As a result, the speaker unit 54 and the symbol display device 41 are notified that the special electric winning device 32 has been fraudulent. After that, "1" is set in the game stop flag provided in the main RAM 66. As a result, the processes for advancing the game (processes in steps S208 to S219) are not executed. Further, in the special electric utility monitoring process (step S206), when the open state winning of the general electric accessory 34a has not occurred, the general electric accessory 34a is based on the state of the detection signal received from the general electric release detection sensor 34b. Determines whether or not is in the open state. Then, when it is specified that the general electric accessory 34a is in the open state, the general electric abnormality notification command is transmitted to the voice emission control device 70. When the voice emission control device 70 receives the general electric abnormality notification command, the voice emission control device 70 controls the sound output of the speaker unit 54 and controls the display control device 90 so that the general electric abnormality notification is performed. As a result, the speaker unit 54 and the symbol display device 41 are notified that the universal electric accessory 34a has been fraudulent. After that, "1" is set in the game stop flag provided in the main RAM 66. As a result, the processes for advancing the game (processes in steps S208 to S219) are not executed.

In the following step S207, it is determined whether or not the progress of the game is stopped by determining whether or not the game stop flag provided in the main RAM 66 is set to "1". If an affirmative determination is made in step S207, the timer interrupt process ends without executing the process for advancing the game (processes in steps S208 to S219). As described above, when the game stop flag in the main RAM 66 is set to "1", the process for advancing the game is not executed.

On the other hand, when a negative determination is made in step S207, the processes after step S208 are executed. In step S208, the port output process is executed. In the port output process, when the output information is set in the previous timer interrupt process, the process for outputting the output corresponding to the output information to the various drive units 32c and 34c is executed. For example, when the information to switch the special electric winning device 32 to the open state is set, the output of the drive signal to the special electric drive unit 32c is started, and when the information to switch to the closed state is set. The output of the drive signal is stopped. Further, when the information for switching the general electric accessory 34a of the second operating port 34 to the open state is set, the output of the drive signal to the general electric drive unit 34c is started and the information for switching to the closed state is started. If is set, the output of the drive signal is stopped.

In the following step S209, the reading process is executed. In the reading process, signals other than the power failure signal and the winning signal are read, and the read information is stored for use in future processing.

The gate winning flag is a flag for the main CPU 64 to specify that one game ball has entered the through gate 35. When "1" is set in the gate winning flag, the main CPU 64 performs the first to first steps of the normal figure holding area 213 in the normal figure general electric control process (step S215 in the timer interrupt process (FIG. 27)) described later. On condition that the number of reserved information on the normal map side stored in the four areas 218a to 218d is less than 4, which is the upper limit, the numerical information of the current general-purpose random number counter C4 is used as the reserved information on the normal map side. The process of storing in the normal figure holding area 213 is executed.

When a negative determination is made in step S323, or when the process of step S324 is performed, the discharge number management process is executed (step S325), and the main ball entry detection process is terminated. In the discharge number management process, it is determined whether or not the value of the discharge number counter in the main RAM 66 has reached "100". When the value of the discharge number counter reaches "100", the discharge information flag in the main RAM 66 is set to "1" and the value of the discharge number counter is subtracted by "100". The discharge information flag is that "100" game balls are discharged from the game area PA through any of the out port 24a, the general winning port 31, the special electric winning device 32, the first operating port 33, and the second operating port 34.

When "1" is set in the discharge information flag, the main CPU 64 receives "100" game balls from the game area PA in the external information setting process (step S219 in the timer interrupt process (FIG. 27)) described later. A process of outputting information indicating that the data has been discharged to the external terminal board 79 is executed.

Returning to the description of the timer interrupt process (FIG. 27), after executing the ball entry detection process in step S210, in step S211, the numerical information of a plurality of types of timer counters provided in the main RAM 66 is collectively updated. Executes the timer update process for. In this case, the timer counters whose stored numerical information is subtracted and updated are aggregated and handled, but both the subtraction type timer counter update and the addition type timer counter update are aggregated. It may be configured.

In the following step S212, a launch control process for controlling the launch of the game ball is executed.

The special figure special electric counter is set to 0 as an initial value.

After executing the process of step S704, in step S705, a process of jumping to the process indicated by the start address acquired in step S704 is executed. Specifically, when the acquired start address is SA0, it jumps to the special figure fluctuation start process in step S706, and when the acquired start address is SA1, it jumps to the special figure change process in step S707. If the acquired start address is SA2, the process jumps to the special figure determination process in step S708, and if the acquired start address is SA3, the process jumps to the special electric start process in step S709, and the acquired start address is If it is SA4, it jumps to the processing during opening of the special electric power in step S710, if the acquired start address is SA5, it jumps to the processing during closing of the special electric power of step S711, and if the acquired start address is SA6. Jump to the special electric end processing in step S712. When any of the processes of steps S706 to S712 is executed, the special figure special electric control process is terminated. Hereinafter, the processes of steps S706 to S712 will be described individually.

<Special figure fluctuation start processing>
First, the special figure variation start processing in step S706 will be described with reference to the flowchart of FIG. 33.

First, in step S801, it is determined whether or not the hold information is stored in any of the first special figure hold area 215 and the second special figure hold area 216. If a negative determination is made in step S801, the special figure fluctuation start process is terminated as it is, and if an affirmative determination is made in step S801, a data setting process is executed (step S802).

In the data setting process in step S802, first, it is determined whether or not the number of reservations in the second special figure reservation area 216 is "0", and when the number of reservations in the second special figure reservation area 216 is "0". Executes the data setting process for the first special figure, and executes the data setting process for the second special figure when the number of reserved figures in the second special figure holding area 216 is not "0". Here, the case where the data setting process is executed is a case where the hold information is stored in either the first special figure holding area 215 or the second special figure holding area 216, as described above. In this case, in the data setting process, it is determined whether or not the number of reserved figures in the second special figure holding area 216 is "0", and if it is not "0", that is, the second special figure display unit 37b is used for variable display. When the hold information of is stored, the data stored in the second special figure hold area 216 is displayed in a variable manner regardless of whether or not the number of holds in the first special figure hold area 215 is 1 or more. I set it for use. As a result, when the hold information is stored in both the first special figure hold area 215 and the second special figure hold area 216, it is stored in the second special figure hold area 216 corresponding to the second operation port 34. The pending information is prioritized as the start target of the game round.

In the data setting process for the first special figure performed in the data setting process (step S802), first, the data stored in the first area 215a of the first special figure holding area 215 is moved to the execution area 217 for the special figure. To do. After that, the process of shifting the data stored in the storage area of the first special figure holding area 215 is executed. This data shift process is a process of sequentially shifting the data stored in the first to fourth areas 215a to 215d to the lower area side, clearing the data of the first area 215a and the second area 215b →. The data in each area is shifted such as 1st area 215a, 3rd area 215c → 2nd area 215b, 4th area 215d → 3rd area 215c. After that, the second special figure flag provided in the main RAM 66 is cleared to "0". The second special figure flag is a flag for specifying whether the start of the variation display this time is either the first special figure display unit 37a or the second special figure display unit 37b. After that, the shift time command, which is information for causing the voice emission control device 70 to recognize that the data in the first special figure holding area 215 has been shifted, is output, and the data setting process is terminated. The voice emission control device 70 suspends the display of the number of hold information corresponding to the first special figure hold area 215 in the symbol display device 41 by transmitting the command corresponding to the received shift command to the display control device 90. Change in response to the decrease in the number. Further, when the number of hold information in the first special figure hold area 215 decreases as described above, the display control process in step S216 in the timer interrupt process (FIG. 27) determines the first special figure hold display unit 37c. On the other hand, the display control is performed so that the display content is changed according to the decrease in the number of pending items.

In the data setting process for the second special figure performed in the data setting process (step S802), first, the data stored in the first area 216a of the second special figure holding area 216 is moved to the execution area 217 for the special figure. To do. After that, the process of shifting the data stored in the storage area of the second special figure holding area 216 is executed. This data shift process is a process of sequentially shifting the data stored in the first to fourth areas 216a to 216d to the lower area side, clearing the data of the first area 216a and the second area 216b →. The data in each area is shifted such as 1st area 216a, 3rd area 216c → 2nd area 216b, 4th area 216d → 3rd area 216c. After that, "1" is set in the second special figure flag provided in the main RAM 66. After that, the shift time command, which is information for causing the voice emission control device 70 to recognize that the data in the second special figure holding area 216 has been shifted, is output, and the data setting process is terminated. The voice emission control device 70 suspends the display of the number of hold information corresponding to the second special figure hold area 216 in the symbol display device 41 by transmitting the command corresponding to the received shift command to the display control device 90. Change in response to the decrease in the number. Further, when the number of hold information in the second special figure hold area 216 decreases as described above, the display control process in step S216 in the timer interrupt process (FIG. 27) determines the second special figure hold display unit 37d. On the other hand, the display control is performed so that the display content is changed according to the decrease in the number of pending items.

After executing the data setting process in step S802, the hit / fail determination process is executed in step S803. In the winning / failing determination process, it is first determined whether or not the winning / failing lottery mode is the high probability mode. In the case of the high probability mode, the hit / fail table for the high probability mode provided in the main ROM 65 is referred to, and among the information stored in the execution area 217 for the special figure, the information for the hit / fail judgment, that is, the winning random number. It is determined whether or not the numerical information acquired from the counter C1 matches the jackpot numerical information for high probability. Further, in the case of the low probability mode, the numerical information acquired from the hit random number counter C1 stored in the execution area 217 for the special figure is referred to by referring to the pass / fail table for the low probability mode provided in the main ROM 65. Determines if is consistent with the low-probability jackpot numerical information.

In the following step S804, it is determined whether or not the result of the winning / failing determination process in step S803 is the jackpot winning result. If it is a jackpot winning result, the distribution determination process is executed in step S805. In the distribution determination process, by determining whether or not "1" is set in the second special figure flag of the main RAM 66, the current game times are held in the first special figure holding area 215 and the second special figure holding. It is determined which of the reserved information in the area 216 corresponds to. Then, the distribution table corresponding to the determination result is the distribution table for the first special figure (see FIG. 25 (a)) and the distribution table for the second special figure (see FIG. 25 (b)). Select from. After selecting the distribution table, the information for distribution determination, that is, the numerical information acquired from the jackpot type counter C2, among the hold information stored in the execution area 217 for the special figure, is the selected distribution. Understand which type of jackpot result is supported in the minute table. Specifically, when the distribution table for the first special figure is selected, the 12R low-accuracy jackpot result, the 5R high-accuracy jackpot result, the 12R high-accuracy jackpot result A, the 12R high-accuracy jackpot result B, and the 16R high. Understand which of the jackpot results corresponds to the jackpot result. When the distribution table for the second special figure is selected, it corresponds to any of the 8R low accuracy jackpot result, the 4R high accuracy jackpot result, the 8R high accuracy jackpot result, and the 16R high accuracy jackpot result. Know if you are doing it.

In the following step S806, the stop result setting process for the jackpot result is executed. Specifically, the jackpot result in which the information on the mode of the pattern to be finally stopped and displayed on the first special figure display unit 37a or the second special figure display unit 37b in this game is stored in the main ROM 65 in advance. It is specified from the stop result table for use, and the specified information is stored in the main RAM 66. In the stop result table for the jackpot result, the type of the pattern mode to be stopped and displayed on the first special figure display unit 37a or the second special figure display unit 37b is set differently for each type of the jackpot result. In step S806, information on the mode of the pattern corresponding to the type of jackpot result specified in step S805 is stored in the main RAM 66.

The information on the type of the pattern to be stopped and displayed is determined according to the value of the jackpot type counter C2. In this case, the mode of the pattern may be set in a one-to-one correspondence with each jackpot result, or a plurality of types of pattern modes may be set for each jackpot result.

In the following step S807, the flag setting process corresponding to the distribution determination result is executed. Specifically, the main RAM 66 is provided with a flag corresponding to each type of jackpot result, and in step S807, among the flags corresponding to each type of jackpot result, the distribution determination result in step S805 is used. Set "1" to the corresponding flag.

On the other hand, if it is determined in step S804 that the result is not the big hit winning result, in step S808, it is determined whether or not the result of the winning / failing determination process in step S803 is the small hit result. If it is a small hit result, the stop result setting process for the small hit result is executed in step S809. Specifically, in this game, the information on the mode of the pattern to be finally stopped and displayed on the first special figure display unit 37a or the second special figure display unit 37b is stored in the main ROM 65 in advance. It is specified from the stop result table for the result, and the specified information is stored in the main RAM 66. The information on the mode of the pattern selected in this case is different from the information on the mode of the pattern selected in the case of the jackpot result. In the following step S810, "1" is set in the small hit flag provided in the main RAM 66. The small hit flag is a flag that enables the main CPU 64 to grasp that a small hit result has occurred in the hit / fail determination process in step S803.

If a negative determination is made in step S808, the stop result setting process for the off result is executed in step S811. Specifically, the information on the mode of the pattern to be finally stopped and displayed on the first special figure display unit 37a or the second special figure display unit 37b in this game is stored in the main ROM 65 in advance. It is specified from the stop result table for use, and the specified information is stored in the main RAM 66. The information on the mode of the pattern selected in this case is different from the information on the mode of the pattern selected in the case of the big hit result and the information on the mode of the pattern selected in the case of the small hit result.

After executing any of the processes of step S807, step S810, and step S811, the display duration acquisition process is executed in step S812. In the acquisition process, the display continues in this game time according to the current game state, the result of the hit / fail judgment process, the result of the distribution judgment process, the presence / absence of reach display, the value of the variation type counter CS, and the number of pending information. Get time information.

In the following step S813, the information corresponding to the display duration acquired in the above step S812 is set in the special figure special electric timer counter. The update of the numerical information set in the timer counter is executed in the timer update process (step S211 in the timer interrupt process (FIG. 27)) described above. By the way, as an effect for the game round, the variation display of the pattern on the first special symbol display unit 37a or the second special symbol display unit 37b and the variation display of the symbol on the symbol display device 41 are performed, and each of these variation displays is performed. When it is terminated, the final stop is displayed over the final stop time in a state where the stop result of the game is displayed (in the symbol display device 41, a predetermined combination of symbols is waiting on the effective line). .. In this case, the display duration acquired in step S812 is the total time for one game, and in step S813, the display duration acquired in step S812 minus the final stop time. Set the information in the special figure special electric timer counter.

In the following step S814, the variation command and the type command are transmitted to the voice emission control device 70. As described above, these variation commands and type commands are transmitted to the voice emission control device 70 via the seventh connector CN7 on the main control board 61. The variable command has a 2-byte data structure, and the 2-byte data includes data corresponding to the result of the hit / fail judgment process, data corresponding to the result of the distribution judgment process, and display duration. It contains the corresponding data. Specifically, identification data for indicating that it is a variable command is set by the upper 4 bits of the 2-byte data, and the hit / fail judgment process is performed by the next 4 bits of data. And the lottery result data corresponding to the result of the distribution determination processing is set, and the holding information of either the 1st special figure holding area 215 or the 2nd special figure holding area 216 is set by the next 1-bit data. Trigger data indicating whether or not it is a trigger is set, and time data corresponding to the display duration is set from the remaining 7-bit data. Therefore, when the voice emission control device 70 receives the variation command, it recognizes that it is the variation command from the identification data, and the result of the hit / fail determination process and the result of the distribution determination process from the lottery result data. Is recognized, and the display duration of the current game times is recognized from the above time data. Here, since the main CPU 64 selects different display durations depending on whether or not reach occurs, the voice emission control device 70 does not include information on whether or not reach has occurred even if the variation command does not include information on whether or not reach has occurred. It is possible to identify the presence or absence of reach from the display duration information. In this respect, it can be said that the variable command contains information indicating whether or not reach has occurred. Note that the variable command may include information that directly indicates whether or not reach has occurred.

The type command has a 2-byte data structure, and the 2-byte data includes data corresponding to the result of the hit / fail judgment process, data corresponding to the result of the distribution judgment process, and a high probability mode. It includes data on whether or not it is in high-frequency support mode and data on whether or not it is in high-frequency support mode. Specifically, identification data for indicating that the command is a type command is set by the upper 4 bits of the 2 bytes of data, and the next 4 bits of the data are used for the pass / fail judgment process and The lottery result data corresponding to the result of the distribution judgment processing is set, and the state recognition data of whether or not it is in the high probability mode and whether or not it is in the high frequency support mode based on the remaining 8-bit data. Is set. Therefore, when the voice emission control device 70 receives the type command, it recognizes that it is a type command from the identification data, and recognizes the result of the winning / failing determination process and the result of the distribution determination process from the lottery result data. Then, from the above state recognition data, it is recognized whether or not it is a high probability mode and whether or not it is a high frequency support mode.

Here, both the variation command and the type command include data corresponding to the result of the hit / miss determination process and the result of the distribution determination process. Therefore, in the voice emission control device 70, by collating the lottery result data included in the variation command with the lottery result data included in the type command, noise or the like may occur in receiving the variation command and the type command. It is possible to identify whether or not a communication abnormality has occurred. Then, when both lottery result data match, the control for production corresponding to the contents of the variation command and the type command is executed, and when both lottery result data do not match. Can notify it. Incidentally, in the latter case, the voice emission control device 70 may execute the game rotation effect corresponding to the communication abnormality in the game time. For example, in the game rotation effect, the hit / fail determination process and the distribution are performed. Regardless of the result of the determination process, the symbol display device 41 may stop and display the combination of symbols corresponding to the complete deviation. In this case, the game rotation effect may be performed over the display duration corresponding to the time data included in the change command, or may be continued until the next change command and type command are received. May be good. It should be noted that the variation command may not include one of the data of the result of the hit / miss determination process and the result of the distribution determination process, or may have a configuration in which both data are not included.

After executing the process of step S814, in step S815, among the first special figure display unit 37a and the second special figure display unit 37b, the display unit on the execution target side of this game round starts the variable display of the pattern. Let me. In the following step S816, the special figure special electric counter is added by 1. In this case, since the numerical information of the special figure special electric counter is "0" when the special figure fluctuation start processing is executed, the numerical information of the special figure special electric counter is "1" when the processing of step S816 is executed. ". After that, the special figure fluctuation start processing is completed.

<Processing during special figure fluctuation>
Next, the process during the change of the special figure in step S707 in the special figure special electric control process (FIG. 32) will be described.

In the special figure changing process, it is determined whether or not the timing is before the final stop display during the duration of the game round, and if it is before the final stop display, the first special figure display unit 37a and the second special figure are displayed. In the figure display unit 37b, a process for regularly changing the display mode of the pattern on the execution target side of the current game round is executed. This regular change continues until it is time to start the final stop display. In addition, this regular change is made in a certain manner regardless of whether or not a hit result is obtained and whether or not a reach display occurs.

In addition, instead of waiting in the special figure changing process until the final stop display timing is reached, if it is not the final stop display timing, after executing the above-mentioned regular change processing, this special figure End the processing during fluctuation. Therefore, after the effect for the game round is started, the special figure changing process is started every time the special figure special electric control process is started until the final stop display timing is reached. Further, when it is time to display the final stop, the symbol display device 41 transmits the final stop command to the voice emission control device 70 and the second stop in order to display the stop result of the current game round as the final stop. Of the 1 special figure display unit 37a and the 2nd special figure display unit 37b, the display mode of the pattern on the execution target side of the current game round is set to the display mode corresponding to the lottery result of the current game round. Further, the information of the final stop time (0.5 seconds) of the game round is read from the main ROM 65 and set in the special figure special electric timer counter. Then, by adding 1 to the value of the special figure special electric counter, the value of the counter is updated from the one corresponding to the special figure changing process to the one corresponding to the special figure finalizing process.

<Processing during special drawing confirmation>
Next, the process during special figure determination in step S708 in the special figure special electric control process (FIG. 32) will be described.

In the process of determining the special figure, it is determined whether or not the final stop time of the current game round has elapsed, and if the final stop time has elapsed, the result of the hit / fail judgment that triggered the current game round. Is a big hit result or a small hit result. If the winning / failing judgment result that triggered this game is neither a big hit result nor a small hit result, the value of the special figure special electric counter is cleared to "0", and the processing during the determination of this special figure is terminated. .. As a result, in the next special figure special electric control process, the special figure change start process will be executed.

On the other hand, in the process during the determination of the special figure, when it is determined that the result of the hit / fail judgment that triggered the game round is the big hit result or the small hit result, the opening time stored in advance in the main ROM 65 ( For example, the information of 4 seconds) is read out, and the information of the opening time is set in the special figure special electric timer counter. After that, the opening command is transmitted to the voice emission control device 70. The opening command is a command for causing the voice emission control device 70 to recognize that it is the timing to start the effect for the opening / closing execution mode. The opening command also includes information indicating which of the various big hit results and the small hit results is the game result that triggered the open / close execution mode. Therefore, the voice emission control device 70 can execute the effect of the open / close execution mode in a manner corresponding to the game result that triggered the open / close execution mode. After that, by adding 1 to the value of the special figure special electric counter, the value of the special figure special electric counter in which "2" is stored is changed to "3", and the processing during the determination of the special figure is completed.

<Special electric start processing>
Next, the special electric start processing in step S709 in the special electric special electric control process (FIG. 32) will be described.

In the special electric power start processing, it is determined whether or not the opening time in the opening / closing execution mode has elapsed, and if it is determined that the opening time has elapsed, the execution trigger of the opening / closing execution mode is one of the jackpot results. It is determined whether or not it is. When it is determined that the execution trigger of the current open / close execution mode is one of the jackpot results, the value of the number of round games corresponding to the current jackpot result is set in the round counter provided in the main RAM 66. , 10 is set in the winning counter PC provided in the main RAM 66. The round counter is a counter for specifying the number of remaining round games by the main CPU 64 in the open / close execution mode, and the winning counter PC is a maximum number of games in one round game or one open / close number specified mode. This is a counter for the main CPU 64 to specify whether or not a ball has been won. After that, the read processing of the open duration corresponding to the jackpot result is executed. Specifically, when the jackpot result that triggered the opening / closing execution mode this time is a 5R high-accuracy jackpot result, information on the opening duration corresponding to the short-time mode is read from the main ROM 65. The opening duration is 0.05 seconds, which is shorter than the firing cycle (0.6 seconds) of the game ball. On the other hand, when the jackpot result that triggered the opening / closing execution mode this time is other than the 5R high-accuracy jackpot result, the information on the opening duration corresponding to the long-time mode is read from the main ROM 65.

On the other hand, when it is determined that the execution trigger of the current open / close execution mode is not any big hit result, that is, when the execution trigger of the current open / close execution mode is the small hit result, the open / close counter provided in the main RAM 66 5 is set to, and 10 is set to the winning counter PC provided in the main RAM 66. The open / close counter is a counter for specifying the number of times the special electric winning device 32 is opened / closed by the main CPU 64 in the open / close execution mode of the open / close number specified mode. After that, the read processing of the open duration corresponding to the small hit result is executed. The opening duration is stored in advance in the main ROM 65, and specifically, it is 0.05 seconds, which is shorter than the firing cycle (0.6 seconds) of the game ball.

When it is determined that the execution trigger of the current opening / closing execution mode is one of the jackpot results, the above-mentioned read processing of the opening duration is executed, or the execution trigger of the current opening / closing execution mode is neither of the jackpot results. When the above-mentioned release duration information is read out in the case of determining that, the read open duration information is set in the special figure special electric timer counter, and the special electric winning device 32 is opened to be in the open state. Execute the setting process. After that, the release command is output. The release command is a command for causing the voice emission control device 70 to recognize that the special electric winning device 32 is released. By receiving the release command, the voice emission control device 70 executes control for switching the effect in the open / close execution mode accordingly. After that, by adding 1 to the special figure special electric counter, the value of the special figure special electric counter in which "3" is stored is changed to "4", and the special electric special electric start processing is terminated.

<Processing while the special electric power is open>
Next, the processing during opening of the special power in step S710 in the special power control processing (FIG. 32) will be described.

In the processing during opening of the special electric power, if the opening / closing execution mode this time is the round number regulation mode, it is determined whether or not the end condition of one round game is satisfied, and if the end condition is satisfied, it is determined. The special electric winning device 32 is closed, and a closing command is transmitted to the voice emission control device 70. Further, it is determined whether or not the value of the round counter after subtraction of 1 is "0", and if it is not "0", the closing time is set in the special figure special electric timer counter. The closing time is constant regardless of the type of game result that triggered the transition to the open / close execution mode, and specifically, it is 2 seconds, which is longer than the firing cycle of the game ball. Further, when the special electric power winning device 32 is closed, the special electric power counter is incremented by 1 regardless of whether or not the value of the round counter is "0". In this case, since the value of the special figure special electric counter when the special electric opening processing is executed is "4", it becomes "5" after 1 addition.

When the opening / closing execution mode this time is the opening / closing number regulation mode, the special electric winning device 32 is closed when the opening duration of the special electric winning device 32 has elapsed, and the closing command is issued to the voice emission control device. Send to 70. Then, it is determined whether or not the value of the open / close counter after subtraction of 1 is "0", and if it is not "0", the closing time is set in the special figure special electric timer counter. As described above, the closing time is constant regardless of the type of game result that triggered the transition to the opening / closing execution mode. Further, if the opening duration has not elapsed, it is determined whether or not a prize has been generated in the special electric winning device 32, and if a prize has been generated, the winning counter is subtracted by 1. Then, when the value of the winning counter after subtraction of 1 is "0", the open / close counter is cleared to "0" and the special electric winning device 32 is closed. Further, when the special electric power winning device 32 is closed, the special electric power counter is incremented by 1 regardless of whether or not the value of the open / close counter is "0". In this case, since the value of the special figure special electric counter when the special electric opening processing is executed is "4", it becomes "5" after 1 addition.

<Processing while the special electric train is closed>
Next, the process during closing of the special electric power in step S711 in the special figure special electric power control process (FIG. 32) will be described.

In the special electric closing processing, it is determined whether or not both the round counter and the open / close counter are "0". If either one is not "0", it is determined whether or not the closing time has elapsed. If the closing time has not passed, the processing during closing of this special electric train is terminated as it is, and if the closing time has passed, the special electric power winning device 32 is opened and the execution trigger of the opening / closing execution mode this time Set the opening duration corresponding to the hit result in the special figure special electric timer counter. Further, when the special electric winning device 32 is opened, the opening command is transmitted to the voice emission control device 70. Then, after subtracting 1 from the special figure special electric counter, the processing during closing of the special electric power is terminated. In this case, since the value of the special figure special electric counter when the special electric power closing process is executed is "5", it becomes "4" after 1 subtraction.

On the other hand, when both the round counter and the open / close counter are "0", the ending command is transmitted to the voice emission control device 70. The ending command is a command for causing the voice emission control device 70 to recognize that it is the timing to start the effect for ending. The ending command also includes information indicating which of the various big hit results and the small hit results is the game result that triggered the open / close execution mode. Therefore, the voice emission control device 70 can execute the ending effect in a manner corresponding to the game result that triggered the opening / closing execution mode. Further, the information of the ending time (for example, 6 seconds) stored in advance in the main ROM 65 is read out, and the information of the ending time is set in the special figure special electric timer counter. By the way, the ending time is constant regardless of the type of game result that triggered the transition to the open / close execution mode. After that, after adding 1 to the special figure special electric counter, the processing during closing of the special electric power is terminated. In this case, since the value of the special figure special electric counter when the special electric power closing process is executed is "5", it becomes "6" after 1 addition.

<Special train end processing>
Next, the special electric power termination process of step S712 in the special figure special electric power control process (FIG. 32) will be described.

In the special train end processing, it is determined whether or not the ending time has elapsed. When it is determined that the ending time has elapsed, the game state transition process is executed, the special figure special electric counter is cleared to "0", and the special electric end process is terminated. Here, the game state transition process will be described.

In the game state transition process, the jackpot result that triggered the transition of the open / close execution mode that ended this time is one of the 16R high-probability jackpot result, the 12R high-probability jackpot result A, the 8R high-probability jackpot result, and the 4R high-probability jackpot result. If, "1" is set for each of the high-probability flag and the high-frequency support flag provided in the main RAM 66, the high-frequency counter provided in the main RAM 66 is cleared to "0", and the game state is set. End the migration process. The high-probability flag is a flag for specifying whether or not the winning / failing lottery mode is the high-probability mode in the main CPU 64, and the high-frequency support flag is whether the support mode is the high-frequency support mode in the main CPU 64. It is a flag for specifying whether or not. Further, the high-frequency counter is a counter for the main CPU 64 to specify the end trigger of the high-frequency support mode in the high-frequency support mode with a limited number of times, and the value set in the high-frequency counter is the game number. 1 is subtracted each time it is finished.

In the situation where the high probability flag is set to "0", the process corresponding to the low probability mode is executed in the pass / fail determination process of step S803 in the special figure fluctuation start process (FIG. 33), and the high probability flag is set. In the situation where "1" is set to, the process corresponding to the high probability mode is executed. Further, in the situation where the high frequency support flag is set to "0", the processing corresponding to the low frequency support mode is executed in the normal power control processing of step S215 in the timer interrupt processing (FIG. 27). In the situation where the high frequency support flag is set to "1", the process corresponding to the high frequency support mode is executed. Further, when the value of the high frequency counter is 1 or more, even if the value of the high frequency support flag is "0", the process corresponding to the high frequency support mode is executed. However, in the open / close execution mode, the process corresponding to the low frequency support mode is executed regardless of whether or not the high frequency support flag is set to "1". Therefore, during the open / close execution mode, the low-frequency support mode is set regardless of whether the support mode immediately before the open / close execution mode is the high-frequency support mode.

In the game state transition process, if the jackpot result that triggered the transition of the open / close execution mode that ended this time is either the 12R high-accuracy jackpot result B or the 5R high-accuracy jackpot result, the high-frequency support flag is set to "1". Is set, or whether or not the value of the high frequency counter is "1" or more is determined. When it is determined that the high-frequency support flag is set to "1" or the high-frequency counter value is "1" or higher, 12R is used in the gaming state, which is the high-frequency support mode. Since it means that the high-probability jackpot result B or the 5R high-probability jackpot result has been obtained, the process for shifting to the gaming state, which is the high-probability mode and the high-frequency support mode, is executed. Specifically, "1" is set for each of the high-probability flag and the high-frequency support flag provided in the main RAM 66, the high-frequency counter provided in the main RAM 66 is cleared to "0", and this game is played. End the state transition process. On the other hand, when it is determined that neither the state in which the high frequency support flag is set to "1" nor the state in which the value of the high frequency counter is "1" or more is determined, in the gaming state in the low frequency support mode. Since it means that the 12R high-probability jackpot result B or the 5R high-probability jackpot result has been obtained, the process for setting the gaming state in the high-probability mode and the low-frequency support mode is executed. Specifically, the high probability flag in the main RAM 66 is set to "1" to end the game state transition process.

In the game state transition process, if the jackpot result that triggered the transition of the open / close execution mode that ended this time is the 8R low probability jackpot result, "15" is set in the high frequency counter provided in the main RAM 66. Clear each of the high probability flag and the high frequency support flag to "0", and end the game state transition process. Therefore, when the 8R low probability jackpot result is obtained, the high frequency support mode is set until the 15 game times, which is the end reference number, is exhausted after the open / close execution mode.

In the game state transition process, when the jackpot result that triggered the transition of the open / close execution mode that ended this time is the 12R low probability jackpot result, the high probability flag, the high frequency support flag, and the high frequency counter in the main RAM 66 are respectively. Is cleared to "0" to end the game state transition process.

In the game state transition process, when the hit result that triggered the transition of the open / close execution mode that ended this time is a small hit result, "30" is set in the small hit post-counter provided in the main RAM 66, and this The game state transition process is terminated. The small hit post-counter is a counter for the main CPU 64 to specify whether or not the game times of the standard number of small hits after the small hit result has already been consumed. The value of the small hit counter is subtracted by 1 each time the game is completed. Further, when the open / close execution mode is changed, the value of the counter after a small hit is cleared to "0". When the value of the counter after the small hit is 1 or more, the display duration in the game round is selected in the corresponding manner after the result of the small hit.

According to the present embodiment described in detail above, the following excellent effects are obtained.

Therefore, it is possible to prevent fraudulent acts of illegally manipulating signals by using a conductive fraudulent jig.

The connector cover 233 exists between the connector group corresponding plate portion 267a and the fixing portions 111b to 116b at the terminals 111 to 116 of the first to fourth connectors CN1 to CN4. Since the connector cover 233 is located closer to the connector group corresponding plate portion 267a than the fixed portions 111b to 116b, the connector cover 233 may prevent the unauthorized jig from coming into contact with the fixed portions 111b to 116b. it can. Since the connector cover 233 is located closer to the main control board 61 than the connector group corresponding plate portion 267a, it is possible to prevent the connector cover 233 from being illegally removed.

The opening area of the first to fourth cover side insertion holes 275 to 278 formed in the connector cover 233 is the opening area of the first to fourth connector insertion holes 270 to 274 formed in the connector group corresponding plate portion 267a. Narrower than. Therefore, as compared with the configuration in which the connector cover 233 is not provided and the first to fourth connectors CN1 to CN4 are inserted only through the first to fourth connector insertion holes 271-276, the first control board 61 has a first position. It is possible to reduce the area of the region exposed to the outside of the substrate box 231 around the fourth connectors CN1 to CN4. As a result, it is possible to reduce the possibility of fraudulent acts in which the conductive fraudulent jig is electrically contacted with the region exposed to the outside of the board box 231 in the main control board 61.

The lower partition wall 237 of the back case body 234 is integrated with a second guide portion 306 that guides the front case body 232 that slides toward the back side facing plate portion 235 upward while being guided by the position adjusting bosses 294 to 297. It is formed. When the front case body 232 is guided upward by the second guide portion 306, the connector cover 233 is guided upward following the front case body 232, and the first to fourth cover side insertion holes 275 to 278 are guided upward. The lower peripheral edges 275b to 278b and the lower standing wall portions 101c to 104c of the first to fourth connectors CN1 to CN4 are in close contact with each other. This makes it possible to reduce the possibility that an unauthorized jig will be inserted between the lower peripheral edges 275b to 278b and the lower standing wall portions 101c to 104c.

<Another form of the second embodiment>
A predetermined play (specifically, a play of about 1 mm) may be provided between the connector group corresponding plate portion 267a and the connector cover 233. As a result, the distance from the fixed portions 111b to 116b of the terminals 111 to 116 of the first to fourth connectors CN1 to CN4 to the surface of the connector group corresponding plate portion 267a can be extended. Therefore, the upper play or the lower upright wall portion existing between the upper upright wall portions 101b to 104b and the upper peripheral edges 271a to 274a of the first to fourth connector insertion holes 271 to 274 from the front case body 232 side. First, a conductive misuse jig such as a wire is inserted into the lower play existing between 101c to 104c and the lower peripheral edges 271b to 274b of the first to fourth connector insertion holes 271 to 274. It is possible to reduce the possibility of fraudulent acts in which the fixing portions 111b to 116b of the terminals 111 to 116 of the fourth connectors CN1 to CN4 are brought into contact with each other.

Extends between the lower peripheral edge portion 362b and between the lower upright wall portion 101c and the lower peripheral edge portion 336b of the first plate side insertion hole 336 so as to straddle along the element mounting surface 61e of the main control board 61. Exists. Further, the fixing portion 112b of the terminal 112 on the other end extends upward from a position closer to the center of the first housing 101 in the lateral direction (closer to the upper standing wall portion 101b), and extends upward from the position of the upper standing wall portion 101b. Along the element mounting surface 61e of the main control board 61 between the upper peripheral edge portion 362a of the first front side connector insertion hole 362 and between the upper standing wall portion 101b and the upper peripheral edge portion 336a of the first plate side insertion hole 336. It extends so as to straddle.

As shown in FIG. 43B, the fixing portion 113b of the terminal 113 of the second connector CN2 extends downward from the central position in the lateral direction of the second housing 102, and extends downward from the lower standing wall portion 102c and the second housing 102. 2 The element mounting surface 61e of the main control board 61 is between the lower peripheral edge portion 363b of the front side connector insertion hole 363 and between the lower standing wall portion 102c and the lower peripheral edge portion 337b of the second plate side insertion hole 337. It extends so as to straddle along. As shown in FIG. 44A, the fixing portion 114b of the terminal 114 of the third connector CN3 extends downward from the central position in the lateral direction of the third housing 103, and extends downward from the lower standing wall portion 103c and the third housing 103. 3 The element mounting surface 61e of the main control board 61 is between the lower peripheral edge portion 364b of the front side connector insertion hole 364 and between the lower upright wall portion 103c and the lower peripheral edge portion 338b of the third plate side insertion hole 338. It extends so as to straddle along.

As shown in FIG. 44 (b), the fixed portion 115b of the terminal 115 on one end side of the fourth connector CN4 is located below the center of the fourth housing 104 in the lateral direction (closer to the lower standing wall portion 104c). The lower peripheral edge of the lower standing wall portion 104c and the lower peripheral edge portion 365b of the fourth front side connector insertion hole 365, and the lower peripheral edge portion of the lower standing wall portion 104c and the fourth plate side insertion hole 339.

It extends so as to straddle.

As shown in FIGS. 43 (a) and 43 (b) and FIGS. 44 (a) and 44 (b), the upper standing wall portions 101b to 104b and the plate side insertion holes 336 to 339 of the first to fourth connectors CN1 to CN4. The size of the play existing between the upper peripheral portions 336a to 339a is based on the size of the play existing between the upper standing wall portions 101b to 104b and the upper peripheral portions 362a to 365a of the front connector insertion holes 362 to 365. Is also small. As described above, since the connector-compatible plate 314 is fixed to the main control board 61, the connector-compatible plate 314 does not follow the front case body 312 even if the front case body 312 (FIG. 42) is slid upward. Therefore, the play existing between the upper standing wall portions 101b to 104b and the upper peripheral peripheral portions 336a to 339a does not spread due to the upward slide of the front case body 312. As a result, a conductive misuse jig such as a wire is formed between the upper standing wall portions 101b to 104b of the first to fourth connectors CN1 to CN4 and the upper peripheral portions 336a to 339a of the plate side insertion holes 336 to 339. The possibility of being inserted can be reduced.

According to the present embodiment described in detail above, the following excellent effects are obtained.

The connector-compatible plate 314 is fixed to the main control board 61. In a state where the connector-compatible plate 314 is fixed to the main control board 61, the connector-compatible plate 314 moves following the main control board 61. Therefore, by moving the front case body 312 with respect to the main control board 61 and the connector compatible plate 314 while the connector compatible plate 314 is fixed to the main control board 61, the first to fourth connectors CN1 to CN4 Positions of the first to fourth front side connector insertion holes 362 to 365 with respect to the first to fourth connector CN1 to CN4 while preventing the positions of the first to fourth plate side insertion holes 336 to 339 from changing. Can be made possible to change.

The front case body 312 has a back case body 313 by screwing the front side first case fixing boss 391 to the front side third case fixing boss 393 to the back side first case fixing boss 394 to the back side third case fixing boss 396. Is fixed to. In a state where the front case body 312 is fixed to the back case body 313, the lower standing wall portions 101c to 104c of the first to fourth connectors CN1 to CN4 and the lower side of the first to fourth front side connector insertion holes 362 to 365. The play existing between the peripheral edges 362b to 365b is the upper peripheral wall portions 101b to 104b of the first to fourth connectors CN1 to CN4 and the upper peripheral edges 362a to the upper peripheral portions 362a to 362 to 365 of the first to fourth front side connector insertion holes 362 to 365. It is smaller than the play that exists between 365a. Therefore, by fixing the front case body 312 to the back case body 313, the play existing between the lower standing wall portions 101c to 104c and the lower peripheral peripheral portions 362b to 365b is reduced to the upper standing wall portions 101b to 104b. It is possible to maintain a state smaller than the play existing between the upper peripheral edge portions 362a to 365a.

Before the front case body 312 is slid upward, the through holes 391a to 393a of the front side first case fixing boss 391 to the front side third case fixing boss 393 and the back side first case fixing boss 394 to the back side third case fixing The screw holes 394a to 396a of the boss 396 are displaced in the vertical direction, and the screws cannot be fixed as they are. After the front case body 312 is slid upward, the through holes 391a to 393a of the front side first case fixing boss 391 to the front side third case fixing boss 393 and the back side first case fixing boss 394 to the back side third case fixing boss The deviation of the 396 screw holes 394a to 396a is eliminated, and the through holes 391a to 393a and the screw holes 394a to 396a are in communication with each other, and the front case body 312 and the back case body 313 are screwed and fixed. It becomes possible. The front case body 312 and the back case body 313 cannot be fixed by screws unless the front case body 312 is slid upward, so that the front case body 312 is not slid upward. It is prevented that the front case body 312 and the back case body 313 are fixed in a state where the slide is performed only halfway.

When the state in which the front case body 312 is fixed to the back case body 313 is released, the free ends of the first to fourth connectors CN1 to CN4 are above and below the first to fourth front side connector insertion holes 362 to 365. It can be in a state of being in the center of the direction. In this state, the lower standing wall portions 101c to 104c and the first to fourth front sides of the first to fourth connectors CN1 to CN4 are compared with the state in which the front case body 312 is fixed to the back case body 313. The size of the play existing between the lower peripheral edges 362b to 365b of the connector insertion holes 362 to 365 is increased. Therefore, in the process of assembling the board box 311, the free ends of the first to fourth connectors CN1 to CN4 are set to be in the center of the first to fourth front side connector insertion holes 362 to 365 in the vertical direction. As a result, the work of inserting the first to fourth connectors CN1 to CN4 into the first to fourth front side connector insertion holes 362 to 365 can be facilitated. After that, the play existing between the lower upright wall portions 101c to 104c and the lower peripheral edge portions 362b to 365b of the first to fourth front side connector insertion holes 362 to 365 is formed between the upper upright wall portions 101b to 104b and the upper peripheral edge. The front case body 312 can be fixed to the back case body 313 in a state smaller than the play existing between the portions 362a to 365a. As a result, the lower upright wall portions 101c to 104c and the lower peripheral edge portions 362b to 365b can be brought into close contact with each other.

By moving the front case body 312 upward with respect to the main control board 61 and the connector-compatible plate 314, the upper peripheral edges of the first to fourth plate side insertion holes 336 to 339 with respect to the first to fourth connectors CN1 to CN4. The upper side of the first to fourth front side connector insertion holes 362 to 365 with respect to the first to fourth connectors CN1 to CN4 while preventing the positions of 336a to 339a and the lower peripheral edges 336b to 339b from changing. The peripheral edges 362a to 365a and the lower peripheral edges 362b to 365b can be moved upward. By moving upward, the lower peripheral edges 362b to 365b of the first to fourth front side connector insertion holes 362 to 365 are brought closer to the lower standing wall portions 101c to 104c of the first to fourth connectors CN1 to CN4. , The play existing between the lower standing wall portions 101c to 104c and the side peripheral edges portions 362b to 365b can be reduced. Due to the upward movement, it exists between the upper standing wall portions 101b to 104b of the first to fourth connectors CN1 to CN4 and the upper peripheral portions 362a to 365a of the first to fourth front side connector insertion holes 362 to 365. Although the play becomes large, the size of the play existing between the upper standing wall portions 101b to 104b and the upper peripheral portions 336a to 339a of the first to fourth plate side insertion holes 336 to 339 does not change. Therefore, on the element mounting surface 61e of the main control board 61, the area of the region exposed to the outside of the board box 311 becomes large around the upper standing wall portions 101b to 104b of the first to fourth connectors CN1 to CN4. While suppressing this, the area of the region exposed to the outside of the substrate box 311 can be reduced around the lower standing wall portions 101c to 104c.

A connector-compatible plate 314 that surrounds the first to fourth connectors CN1 to CN4 is provided between the main control board 61 and the front case body 312. The play existing between the upper standing wall portions 101b to 104b of the first to fourth connectors CN1 to CN4 and the upper peripheral portions 336a to 339a of the first to fourth plate side insertion holes 336 to 339 is the upper standing wall portion. It is smaller than the play existing between 101b to 104b and the upper peripheral edges 362a to 365a of the first to fourth front side connector insertion holes 362 to 365. Therefore, the connector-compatible plate 314 allows the upper standing wall portions 101b to 104b to reach the outside of the board box 311 through play existing between the upper peripheral portions 362a to 365a of the first to fourth front side connector insertion holes 362 to 365a. The range of the exposed main control board 61 can be narrowed. As a result, a conductive misuse jig such as a wire is inserted into the play existing between the upper standing wall portions 101b to 104b and the upper peripheral portions 362a to 365a of the first to fourth front side connector insertion holes 362 to 365. It is possible to reduce the possibility that the fraudulent jig will reach the terminals 111 to 116 and the wiring pattern existing on the element mounting surface 61e of the main control board 61 when the fraudulent act is performed. Therefore, it is possible to prevent fraudulent acts of illegally manipulating signals by using a conductive fraudulent jig.

The connector-corresponding plate 314 exists between the connector group-corresponding plate portion 361a and the fixing portions 111b to 116b at the terminals 111 to 116 of the first to fourth connectors CN1 to CN4. Since the connector-compatible plate 314 exists on the connector group-compatible plate portion 361a side of the fixing portions 111b to 116b, the connector-compatible plate 314 prevents the unauthorized jig from coming into contact with the fixing portions 111b to 116b. be able to. Since the connector-compatible plate 314 is present on the main control board 61 side of the connector group-compatible plate portion 361a, it is possible to prevent the connector-compatible plate 314 from being illegally removed.

The opening areas of the first to fourth plate side insertion holes 336 to 339 formed in the connector corresponding plate 314 are the opening areas of the first to fourth front side connector insertion holes 362 to 365 formed in the connector group corresponding plate portion 361a. It is narrower than the opening area. Therefore, in the main control board 61, as compared with the configuration in which the connector-compatible plate 314 is not provided and the first to fourth connectors CN1 to CN4 are inserted only through the first to fourth front side connector insertion holes 362 to 365. The area of the region exposed to the outside of the substrate box 311 around the first to fourth connectors CN1 to CN4 can be reduced. As a result, it is possible to reduce the possibility of fraudulent acts in which the conductive fraudulent jig is electrically contacted with the region exposed to the outside of the board box 311 in the main control board 61.

<Another form of the third embodiment>
The connector-compatible plate 314 is fixed to the main control board 61 in such a manner that the upper standing wall portions 101b to 104b of the first to fourth connectors CN1 to CN4 and the upper peripheral edges 336a to 339a of the connector-compatible plate 314 are in contact with each other. May be. Specifically, in the main control board 61, a pair of left and right plate fixing holes that allow screws 349 for fixing the connector-compatible plate 314 to the main control board 61 can be inserted at both ends of the connector group mounting area 88 in the longitudinal direction. And a plate position adjusting hole that allows the free end of the plate position adjusting bosses 343 and 344 extending from the plate-shaped portion 335 of the connector-corresponding plate 314 to be inserted are formed. These plate fixing holes and plate position adjusting holes are through holes that penetrate the main control board 61 in the plate thickness direction. In this configuration, the connector-compatible plate 314 is fixed to the main control board 61 in such a manner that the upper standing wall portions 101b to 104b of the first to fourth connectors CN1 to CN4 and the upper peripheral edges 336a to 339a of the connector-compatible plate 314 are in contact with each other. A plate fixing hole and a plate position adjusting hole are formed at the positions to be formed.

In the process of assembling the main control device 310, the connector-corresponding plate 314 is inserted into the plate-side insertion holes 336 to 339 corresponding to the first to fourth connectors CN1 to CN4, and then the two plate position adjusting bosses 343 and 344 are inserted. It is assumed that it is inserted through the two corresponding plate position adjustment holes. By inserting the two plate position adjusting bosses 343 and 344 into the corresponding two plate position adjusting holes, the fixing position of the connector corresponding plate 314 with respect to the main control board 61 is determined. After that, the plate fixing bosses 341 and 342 are screwed to the main control board 61 from the back side of the main control board 61 to be fixed to the main control board 61. In a state where the connector-compatible plate 314 is fixed to the main control board 61, the first to fourth connectors CN1 to CN4 are inserted into the corresponding plate-side insertion holes 336 to 339, and the first to fourth connectors CN1 are inserted. The upper standing wall portions 101b to 104b of ~ CN4 are in contact with the upper peripheral portions 336a to 339a of the connector-corresponding plate 314. This makes it possible to prevent a conductive misuse jig such as a wire from being inserted between the other end of the first to fourth connectors CN1 to CN4 and the plate-shaped portion 335. Therefore, it is possible to prevent fraudulent activity in which the conductive fraudulent jig is brought close to the terminals 112 and 116 on the other ends of the first connector CN1 and the fourth connector CN4.

In the front case body 312, as already described in the third embodiment, the lower peripheral edges 362b to 365b of the first to fourth front side connector insertion holes 362 to 365 are below the first to fourth connectors CN1 to CN4. It is slid upward until it comes close to the side standing wall portions 101c to 104c, and is fixed to the back case body 313 in the state where the slide is completed. The lower upright wall portions 101c to 104c of the first to fourth connectors CN1 to CN4 and the lower peripheral edges 362b to 365b of the first to fourth front side connector insertion holes 362 to 365 are close to each other, and the first to first to fourth connectors are close to each other. The first to first ones are configured such that the upper upright wall portions 101b to 104b of the fourth connectors CN1 to CN4 and the upper peripheral edges 336a to 339a of the first to fourth plate side insertion holes 336 to 339 are in contact with each other.

Alternatively, in this state, the connector group-corresponding plate portion 361a may be in a state of approaching the plate-shaped portion 335 of the connector-corresponding plate 314 at a predetermined interval (approximately 1 mm interval). The predetermined interval is an interval that makes it difficult to insert a conductive fraudulent jig such as a wire. Even if the configurations are such that they are brought close to each other at a predetermined interval, it is possible to prevent the unauthorized jig from being inserted due to the play existing between the plate portion 361a corresponding to the connector group and the plate-shaped portion 335. ..

The fixing portions 111b to 116b of the terminals 111 to 116 of the first to fourth connectors CN1 to CN4 may be in contact with the connector-compatible plate 314. As a result, the distance between the element mounting surface 61e of the main control board 61 and the connector-compatible plate 314 can be reduced. Therefore, a conductive misuse jig such as a wire is inserted from the upper play existing between the upper standing wall portions 101b to 104b and the upper peripheral portions 156a to 159a of the first to fourth connector insertion holes 156 to 159. Then, a fraudulent act of contacting the fixed portions 111b, 113b to 115b of the terminal 111 on one end side of the first connector CN1, the terminal 112 of the second connector CN2, the terminal 113 of the third connector CN3, and the terminal 115 on one end side of the fourth connector CN4. Can be prevented.

The front case in a state where the lower standing wall portions 101c to 104c of the first to fourth connectors CN1 to CN4 and the lower peripheral edges 362b to 365b of the first to fourth front side connector insertion holes 362 to 365 are in contact with each other. The body 312 may be fixed to the back case body 313. In this configuration, the front case body 312 is manually slid upward with respect to the back case body 313, the main control board 61, and the connector compatible plate 314 until the position adjustment bosses 381 to 384 come into contact with the upper ends of the boss insertion holes 385 to 388. By doing so, the lower upright wall portions 101c to 104c and the lower peripheral edge portions 362b to 365b can be brought into contact with each other. As a result, it is possible to prevent fraudulent acts of inserting a conductive fraudulent jig such as a wire between the lower standing wall portions 101c to 104c and the lower peripheral edge portions 362b to 365b.

As already described with reference to FIG. 7 in the first embodiment, the main control device 60 is mounted so that the surface of the front case body 121 faces the rear of the pachinko machine 10. In the installed state in the game hall, the element mounting surface 401e of the main control board 401 faces the rear of the pachinko machine 10, and the solder surface 401f faces the front of the pachinko machine 10. By opening the gaming machine main body 12 from the outer frame 11 to the front of the pachinko machine 10, the back side of the gaming machine main body 12 becomes visible. In this case, the main control device 60 constitutes the back portion of the gaming machine main body 12, and further, since the surface of the front case body 121 faces the rear of the pachinko machine 10 as described above, the gaming machine main body 12 is removed. By opening to the frame 11, the element mounting surface 401e of the main control board 401 becomes visible through the transparent front case body 121.

A configuration for detecting these frauds will be described.

As shown in FIG. 47 (a), the element mounting surface 401e of the main control board 401 is provided with a GND line 405 that goes around the peripheral edge of the element mounting surface 401e, and is more main than the GND line 405. A fraud detection line 406 that goes around the peripheral edge of the element mounting surface 401e is provided at a position closer to the center of the control board 401. The GND line 405 and the fraud detection line 406 are formed by etching a conductive metal foil (specifically, a copper foil).

The fraud detection line 406 is an electrical wiring that makes it possible to grasp that a conductive fraud jig such as a minus driver has been inserted from the side surface side of the main control device 60 or the like. A fraud detection voltage (specifically, a + 5V voltage) is supplied to the fraud detection line 406. When the main CPU 64 monitors the voltage of the fraud detection line 406 and finds that the fraud detection line 406 and the GND line 405 are conducted by a conductive fraud jig and the voltage of the fraud detection line 406 drops. To identify that fraud has been committed.

The GND line 405 includes an upper GND line 405a that extends linearly with a predetermined width (specifically, a width of about 1.5 mm) from the left end to the right end of the upper side 401a along the upper side 401a of the main control board 401. A lower GND line 405b extending linearly with a predetermined width (specifically, a width of about 1.5 mm) from the left end to the right end of the lower side 401b along the lower side 401b of the control board 401, and the left side of the main control board 401.

It is provided with a right-side GND line 405d that extends linearly from the upper end to the lower end of the 401d with a predetermined width (specifically, a width of about 1.5 mm).

The fraud detection line 406 includes an upper fraud detection line 406a provided at a distance of approximately 1 mm below the upper GND line 405a and a lower side provided at a distance of approximately 1 mm above the lower GND line 405b. The fraud detection line 406b, the left fraud detection line 406c provided at a distance of approximately 1 mm to the right from the left GND line 405c, and the right side provided at a distance of approximately 1 mm to the left from the right GND line 405d. It is equipped with a fraud detection line 406d. The upper fraud detection line 406a extends linearly from the upper end of the left fraud detection line 406c to the upper end of the right fraud detection line 406d with a predetermined width (specifically, a width of about 1.5 mm), and the lower fraud detection line 406a. The detection line 406b extends linearly from the lower end of the left fraud detection line 406c to the lower end of the right fraud detection line 406d with a predetermined width (specifically, a width of about 1.5 mm). The top, bottom, left, and right fraud detection lines 403a to 403d are electrically connected.

The peripheral edge of the element mounting surface 401e is doubly surrounded by the outer GND line 405 and the inner fraud detection line 406. These GND lines 405 and fraud detection line 406 are exposed on the surface of the main control board 401, and when a conductive fraudulent jig comes into contact with the GND line 405 and fraud detection line 406, the GND line 405 and fraud detection are detected. Line 406 is conducted. Since the fraud detection line 406 is provided close to the GND line 405, when the conductive fraudulent jig is brought closer to the element mounting surface 401e, the fraud detection jig will be used for the GND line 405 and the fraud detection. There is a high possibility that the voltage of the fraud detection line 406 will drop because it is in contact with both lines 406.

A large number of GND contact portions 407 are formed on the top, bottom, left, and right GND lines 405a to 405d so as to form one row in the extending direction of the GND lines 405a to 405d.

The GND contact portion 407 includes a solder bulging portion 407d that bulges approximately 1 mm from the solder surface 401f. The solder bulging portion 407d is formed by allowing solder to flow into the inside of the through hole 407a and the land 407c on the solder surface 401f side from the solder surface 401f side. The solder bulging portions 407d of all GND contact portions 407 are electrically connected to the GND line 405. Since the solder bulging portion 407d bulges from the solder surface 401f, the possibility that the conductive fraudulent jig brought close to the solder surface 401f comes into contact with the solder bulging portion 407d is increased. In the top, bottom, left, and right GND lines 405a to 405d, the GND contact portions 407 are provided at equal intervals so that the distance between the centers of the adjacent GND contact portions 407 is approximately 3 mm. As a result, the possibility that the conductive misuse jig brought close to the solder surface 401f comes into contact with the solder bulging portion 407d of any of the GND contact portions 407 is increased.

A large number of fraud detection contact portions 408 are formed on the top, bottom, left, and right fraud detection lines 406a to 406d so as to form one row in the extending direction of the fraud detection lines 406a to 406d. As shown in FIG. 48 (b), the fraud detection contact portion 408 penetrates the main control board 401 in the plate thickness direction, and its inner peripheral surface is plated with a conductive metal (specifically, copper).

The fraud detection contact portion 408 includes a solder bulging portion 408d that bulges approximately 1 mm from the solder surface 401f. The solder bulging portion 408d is formed by allowing solder to flow into the inside of the through hole 408a and the land 408c on the solder surface 401f side from the solder surface 401f side. The solder bulging portions 408d of all fraud detection contact portions 408 are electrically connected to the fraud detection line 406. Since the solder bulging portion 408d bulges from the solder surface 401f, the possibility that the conductive fraudulent jig brought close to the solder surface 401f comes into contact with the solder bulging portion 408d is increased. In the up, down, left, and right fraud detection lines 406a to 406d, the fraud detection contact portions 408 are provided at equal intervals so that the distance between the centers of the adjacent fraud detection contact portions 408 is approximately 3 mm. As a result, the possibility that the conductive fraudulent jig brought close to the solder surface 401f comes into contact with the solder bulging portion 408d of any fraud detection contact portion 408 is increased.

As described above, the fraud detection line 406 is provided close to the GND line 405 on the element mounting surface 401e. Therefore, the fraud detection contact portion 408 and the GND contact portion 407 are close to each other on the solder surface 401f. As a result, when the conductive fraudulent jig is brought close to the solder surface 401f, one or more GND contact portions 407 and one or more fraud detection contact portions 408 are in contact with each other, and the fraud detection line 406 There is an increased possibility that the voltage of the solder will drop.

As shown in FIGS. 47 (a) and 47 (b), the MPU 402 is mounted near the center of the element mounting surface 401e of the main control board 401.

A copper wiring 414 is formed that electrically connects the GND contact portion 407 and the GND connection pin 411 of the MPU 402. The wiring 414 is covered with an insulator resist (not shown) so as not to be exposed on the surface.

As shown in FIG. 47 (a), the first connector CN41 is mounted on the upper side 401a side of the element mounting surface 401e of the main control board 401. The first connector CN41 includes a large number of pins 415 and 416 (FIG. 48 (a)), and one of the large number of pins 415 and 416 supplies a voltage to the fraud detection line 406 (FIG. 48 (a)). It is a voltage supply pin 415 (FIG. 48 (a)). The large number of pins 415 and 416 including the voltage supply pin 415 are soldered on the solder surface 401f. As shown in FIG. 48A, one fraud detection contact portion 408 provided near the right side 401d of the main control board 401 and the fraud detection connection pin 412 of the MPU 402 are electrically connected to the solder surface 401f. The copper wiring 417 is formed, and the copper wiring 417 is electrically connected to the one fraud detection contact portion 408 provided near the upper side 401a of the main control board 401 and the voltage supply pin 415 of the first connector CN41. Wiring 418 is formed. These wirings 417 and 418 are covered with an insulator resist (not shown) so as not to be exposed on the surface.

In a state where the operating power is being supplied to the pachinko machine 10, the fraud detection line 406 is connected to the fraud detection line 406 via the voltage supply pin 415 and the wiring 418 of the first connector CN41 to detect fraud (specifically, + 5V voltage) is supplied, and the fraud detection voltage is supplied to the input side of the MPU 402 via the fraud detection line 406, the fraud detection connection pin 412, and the wiring 417. The main CPU 64 monitors the voltage supplied to the input side of the MPU 402 via the fraud detection connection pin 412, and when the voltage is the fraud detection voltage, it can be grasped that it is in a normal state. it can.

As described above, the GND contact portion 407 and the fraud detection contact portion 408 are close to each other on the solder surface 401f of the main control board 401. Therefore, a conductive fraudulent jig such as a minus driver is inserted from the side surface side of the main control device 60 to the solder surface 401f side and is in contact with the GND contact portion 407 and the fraud detection contact portion 408. In that case, the GND line 405 and the fraud detection line 406 are conducted by the fraud jig. Further, as described above, the GND line 405 and the fraud detection line 406 are provided close to each other on the element mounting surface 401e of the main control board 401. Therefore, a conductive fraudulent jig such as a minus driver is inserted from the side surface side or the front side of the main control device 60 to the element mounting surface 401e side and is in contact with the GND line 405 and the fraud detection line 406. In that case, the GND line 405 and the fraud detection line 406 are conducted by the fraud jig. When the main CPU 64 monitors the voltage of the fraud detection line 406 and identifies that the GND line 405 and the fraud detection line 406 are conducted and the voltage of the fraud detection line 406 drops, an abnormality occurs in the fraud detection line 406. Know what happened.

Next, the fraud detection process executed by the main CPU 64 will be described with reference to the flowchart of FIG. The fraud detection process is executed in step S205 of the timer interrupt process (FIG. 27).

In the fraud detection process, first, the voltage of the fraud detection line 406 connected to the input side of the MPU 402 is monitored, and it is determined whether or not a drop in the voltage is detected (step S901). If a negative determination is made in step S901, it is determined whether or not the monitoring target is fraudulent (step S902). In step S902, the monitoring target is based on the detection signals received from the radio wave detection sensor 202 and the magnetic detection sensor 203, as in the fraud detection process (step S205 of the timer interrupt process (FIG. 27)) in the first embodiment. Identify that fraud has occurred. If the fraud to be monitored has not occurred (step S902: NO), the fraud detection process is terminated as it is.

If an affirmative determination is made in step S901, or if an affirmative determination is made in step S902, the abnormality notification process is executed (step S903). In the abnormality notification process, an abnormality notification command is transmitted to the voice emission control device 70. The abnormality notification command is a command for causing the voice emission control device 70 to execute a process for performing abnormality notification for notifying that an abnormality, a radio wave abnormality, or a magnetic abnormality has occurred in the fraud detection line 406. When the voice emission control device 70 receives the abnormality notification command, the voice emission control device 70 controls the sound output of the speaker unit 54, the light emission control of the display light emission unit 53, and the display control device 90 for notifying that the fraud is detected. .. As a result, it is possible to grasp from the outside of the pachinko machine 10 that an abnormality in the fraud detection line 406, a radio wave abnormality, or a magnetic abnormality has been detected. Further, in the abnormality notification process in step S903, an abnormality signal is output to the management computer (not shown) of the game hall, which is an external device. As a result, it is possible for the management computer to grasp that an abnormality, a radio wave abnormality, or a magnetic abnormality of the fraud detection line 406 has been detected.

After that, "1" is set in the game stop flag in the main RAM 66 (step S904), and the fraud detection process ends. As already described in the first embodiment, the process for advancing the game in the timer interrupt process (FIG. 27) by setting the game stop flag to "1" (processes in steps S208 to S219). Will not be executed.

According to the present embodiment described in detail above, the following excellent effects are obtained.

All GND contact parts 407 are electrically connected to the GND line 405, and all fraud detection contact parts 408 are electrically connected to the fraud detection line 406. The GND contact portion 407 and the fraud detection contact portion 408 include solder bulging portions 407d and 408d that bulge from the solder surface 401f. A conductive fraudulent jig is brought close to the solder surface 401f of the main control board 401, and the fraudulent jig is a solder bulging portion 407d and one or more fraud detection contact portions 408 in one or more GND contact portions 407. When the solder bulging portion 408d is in contact with both of the solder bulging portions 408d, the GND line 405 and the fraud detection line 406 are electrically connected. When the main CPU 64 monitors the voltage of the fraud detection line 406 and finds that the fraud detection line 406 and the GND line 405 are conducted by a conductive fraud jig and the voltage of the fraud detection line 406 drops. To identify that fraud has been committed. As a result, it is possible to detect an illegal act of inserting a conductive illegal use jig on the solder surface 401f side of the main control board 401. When pins 411 to 413,415,416 of various electronic components are fixed by solder on the solder surface 401f, when a fraudulent act is performed in which a conductive fraudulent jig is brought into contact with the fixed portion by solder and its periphery. There is a risk that the signal transmitted from various electronic components or the signal received by various electronic components may be tampered with. On the other hand, by making it possible to grasp the fraudulent act of bringing the conductive fraudulent jig close to the solder surface 401f, the possibility that the fraudulent act is performed without the manager of the game hall noticing is reduced. Has been done.

On the element mounting surface 401e, the fraud detection line 406 and the GND line 405 are exposed on the surface. For this reason, when a fraudulent act of bringing a conductive fraudulent jig closer to the element mounting surface 401e is performed and the fraudulent jig is in contact with both the GND line 405 and the fraud detection line 406, , The GND line 405 and the fraud detection line 406 are conducted, and the voltage of the fraud detection line 406 drops. As a result, it is possible to grasp that the fraudulent act has been committed.

On the element mounting surface 401e, the fraud detection line 406 is arranged side by side with the GND line 405.

The possibility of voltage drop is increased.

When the main CPU 64 detects a voltage drop in the fraud detection line 406, it executes an abnormality notification process. As a result, the abnormality of the fraud detection line 406 can be notified to the manager of the game hall.

Each of the GND line 405 and the fraud detection line 406 is provided along the peripheral edge portion of the element mounting surface 401e of the main control board 401. Therefore, when a fraudulent act is performed in which the conductive fraudulent jig approaches the element mounting surface 401e side of the main control board 401 from the side surface side of the main control device 60, the fraudulent jig detects the GND line 405 and the fraudulent act. It is possible to increase the possibility that the line 406 will be in a conductive state. As a result, the fraudulent activity can be grasped at an early stage.

Each of the GND line 405 and the fraud detection line 406 is provided over the entire circumference of the peripheral edge portion of the element mounting surface 401e of the main control board 401. Therefore, as compared with the configuration in which at least one of the GND line 405 and the fraud detection line 406 is provided only on a part of the peripheral edge of the element mounting surface 401e, the main control board 401 is viewed from the side surface side of the main control device 60. When a fraudulent act is performed in which a conductive fraudulent jig approaches the element mounting surface 401e, it is possible to increase the possibility that the GND line 405 and the fraud detection line 406 are connected by the fraudulent jig. .. As a result, the fraudulent activity can be grasped at an early stage.

The main control board 401 is provided with a large number of GND contact portions 407 along the GND line 405, and is provided with a large number of fraud detection contact portions 408 along the fraud detection line 406. All GND contact parts 407 are electrically connected to the GND line 405, and all fraud detection contact parts 408 are electrically connected to the fraud detection line 406. The GND contact portion 407 and the fraud detection contact portion 408 include solder bulging portions 407d and 408d that bulge from the solder surface 401f. Since the solder bulging portion 407d of the GND contact portion 407 bulges from the solder surface 401f, the conductive illegal jig brought closer to the solder surface 401f side of the main control board 401 causes the solder bulging portion 407 of the GND contact portion 407 to bulge. The possibility of electrical contact with the portion 407d is increased. Since the solder bulging portion 408d of the fraud detection contact portion 408 bulges from the solder surface 401f, the conductive fraudulent jig brought closer to the solder surface 401f side of the main control board 401 is soldered to the fraud detection contact portion 408. The possibility of electrical contact with the bulging portion 408d is increased. Therefore, when a conductive illegal jig is brought close to the solder surface 401f where various electronic components mounted on the main control board 401 and the main control board 401 are fixed by soldering, the jig is brought close to the solder surface 401f. It is possible to increase the possibility that the solder bulging portion 407d of the GND contact portion 407 and the solder bulging portion 408d of the fraud detection contact portion 408 are in a conductive state by the fraudulent jig. When pins 411 to 413,415,416 of various electronic components are fixed by solder on the solder surface 401f, when a fraudulent act is performed in which a conductive fraudulent jig is brought into contact with the fixed portion by solder and its periphery. There is a risk that the signal transmitted from various electronic components or the signal received by various electronic components may be tampered with. On the other hand, by making it possible to grasp the fraudulent act of bringing the conductive fraudulent jig close to the solder surface 401f, the possibility that the fraudulent act is performed without the manager of the game hall noticing is reduced. Has been done.

On the solder surface 401f, the solder bulging portion 408d of the fraud detection contact portion 408 is arranged side by side with the solder bulging portion 407d of the GND contact portion 407. As a result, when the conductive fraudulent jig is brought closer to the solder surface 401f side, the fraudulent jig is attached to the solder bulging portion 407d of the GND contact portion 407 and the solder bulging portion 408d of the fraud detection contact portion 408. There is a high possibility that the voltage of the fraud detection line 406 will drop because it is in contact with both.

The peripheral edge of the solder surface 401f is intermittently arranged at a position closer to the center of the main control board 401 than the solder bulging portion 407d of the GND contact portion 407 and the solder bulging portion 407d of the GND contact portion 407. It is doubly surrounded by the solder bulging portion 408d of the fraud detection contact portion 408 arranged so as to be. Therefore, when the conductive fraudulent jig is brought closer to the solder surface 401f side of the main control board 401 from the side surface side of the main control device 60, the fraudulent jig becomes the solder bulging portion 407d of the GND contact portion 407 and the solder bulging portion 407d. There is an increased possibility that the voltage of the fraud detection line 406 will drop because the fraud detection contact portion 408 is in contact with both the solder bulging portions 408d.

The GND line 405 is a continuous upper GND line 405a, lower GND line 405b, and left GND line 405c on the upper peripheral edge portion, the lower peripheral edge portion, the left peripheral peripheral portion, and the right peripheral edge portion on the element mounting surface 401e of the main control board 401. And the right side GND line 405d. Therefore, as compared with the configuration in which the GND lines 405a to 405c are intermittently formed, when the conductive fraudulent jig is brought closer to the main control board 401, any of the fraudulent jigs is used. It is possible to increase the possibility of contacting the GND lines 405a to 405d.

The four GND lines 405a to 405d are connected to the ground of the main control board 401. As a result, when the conductive fraudulent jig comes into contact with any of the GND lines 405a to 405d and the fraud detection line 406 and the GND line 405 and the fraud detection line 406 become conductive, the fraud detection is performed. It is possible to create a state in which the voltage at line 406 is dropping. Therefore, it is possible to easily identify that the GND line 405 and the fraud detection line 406 are in a conductive state.

The fraud detection line 406 is located on the element mounting surface 401e of the main control board 401 at a position closer to the center than the four GND lines 405a to 405d, and is a continuous upper fraud detection line 406a, lower fraud detection line 406b, and left fraud detection line. It is equipped with a 406c and a right fraud detection line 406d. Therefore, as compared with the configuration in which the fraud detection lines 406a to 406c are intermittently formed, when the conductive fraudulent jig is brought closer to the main control board 401, the fraudulent jig will eventually be used. The possibility of contacting the fraud detection lines 406a to 406d can be increased.

A fraud detection voltage is supplied to all of the four fraud detection lines 406a to 406d. As a result, if the conductive fraudulent jig is in contact with both the GND lines 405a to 405d and the fraud detection lines 406a to 406d, the fraudulent jig is fraudulent. Regardless of where the detection lines 406a to 406d are touched, it is possible to create a state in which the voltage in the fraud detection line 406 is reduced as the GND line 405 and the fraud detection line 406 are electrically connected. .. Therefore, it is possible to easily identify that the GND line 405 and the fraud detection line 406 are in a conductive state.

The GND contact portion 407 is such that the distance between the centers of the adjacent GND contact portions 407 is approximately 3 mm along the upper GND line 405a, the lower GND line 405b, the left GND line 405c, and the right GND line 405d. It is provided at intervals. As a result, the possibility that the conductive misuse jig brought close to the solder surface 401f comes into contact with the solder bulging portion 407d of any of the GND contact portions 407 is increased.

In the fraud detection contact portion 408, the distance between the centers of the adjacent fraud detection contact portions 408 is approximately approximately along the upper fraud detection line 406a, the lower fraud detection line 406b, the left fraud detection line 406c, and the right fraud detection line 406d. It is provided at equal intervals so as to be 3 mm. As a result, the possibility that the conductive fraudulent jig brought close to the solder surface 401f comes into contact with the solder bulging portion 408d of any fraud detection contact portion 408 is increased.

<Another form of the fourth embodiment>

The configuration may be different from the mode of the abnormality notification performed in. Specifically, when an abnormality in the fraud detection line 406 is detected, the main CPU 64 transmits a first abnormality notification command to the voice emission control device 70 in the abnormality notification process. The first abnormality notification command is a command for causing the voice emission control device 70 to execute a process for performing the first abnormality notification for notifying that an abnormality in the fraud detection line 406 has been detected.

The control device 90 is controlled. In the first abnormality notification, a voice "first abnormality has occurred" is output from the speaker unit 54, the display light emitting unit 53 is controlled to emit light in a manner corresponding to the abnormality of the fraud detection line 406, and the display surface 41a of the symbol display device 41 The characters "first abnormality occurred" are displayed in. As a result, it is possible to grasp from the outside of the pachinko machine 10 that an abnormality in the fraud detection line 406 has been detected. When an abnormality in the fraud detection line 406 is detected, the main CPU 64 outputs a first abnormality signal to the management computer (not shown) of the game hall, which is an external device, in the abnormality notification process. As a result, it is possible for the management computer to grasp that an abnormality in the fraud detection line 406 has been detected.

When a radio wave abnormality or a magnetic abnormality is detected, the main CPU 64 transmits a second abnormality notification command to the voice emission control device 70 in the abnormality notification process. The second abnormality notification command is a command for causing the voice emission control device 70 to execute a process for performing a second abnormality notification for notifying that a radio wave abnormality or a magnetic abnormality has been detected. When the voice light emission control device 70 receives the second abnormality notification command, the sound output control of the speaker unit 54, the light emission control and the display control of the display light emission unit 53 for notifying that a radio wave abnormality or a magnetic abnormality has been detected. Control the device 90. In the second abnormality notification, a voice "second abnormality has occurred" is output from the speaker unit 54, the display light emitting unit 53 is controlled to emit light in a manner corresponding to a radio wave abnormality or a magnetic abnormality, and is displayed on the display surface 41a of the symbol display device 41. The characters "second anomaly have occurred" are displayed. As a result, it is possible to grasp from the outside of the pachinko machine 10 that a radio wave abnormality or a magnetic abnormality has been detected. When a radio wave abnormality or a magnetic abnormality is detected, the main CPU 64 outputs a second abnormality signal to the management computer (not shown) of the game hall, which is an external device, in the abnormality notification process. As a result, it is possible for the management computer to grasp that a radio wave abnormality or a magnetic abnormality has been detected.

In this way, in a configuration in which a second abnormality notification is performed when a radio wave abnormality or a magnetic abnormality is detected, when an abnormality in the fraud detection line 406 is detected, a first abnormality notification different from the second abnormality notification is performed. With the configuration in which the above is performed, it is possible to quickly grasp that an abnormality in the fraud detection line 406 has been detected.

The plate surface on which the wiring 417 to be connected and the wiring 418 for electrically connecting one fraud detection contact portion 408 and the voltage supply pin 415 of the first connector CN41 is formed is not limited to the solder surface 401f. .. A part or all of these wirings 414, 417, 418 may be formed on the element mounting surface 401e.

In the main control board 401, a plate surface on which the GND line 405 is provided (element mounting surface 401e in the fourth embodiment) and a plate surface on which the solder bulging portion 407d of the GND contact portion 407 is provided (fourth). In the embodiment of the above, the solder surface 401f) may be reversed. By configuring the solder bulging portion 407d of the GND contact portion 407 to bulge toward the element mounting surface 401e, the conductive fraudulent jig brought closer to the element mounting surface 401e side of the main control board 401 comes into contact with the GND. The possibility of contact with the portion 407 can be increased.

In the main control board 401, a plate surface provided with a fraud detection line 406 (element mounting surface 401e in the fourth embodiment) and a plate surface provided with a solder bulging portion 408d of the fraud detection contact portion 408 (in the fourth embodiment). In the fourth embodiment, the solder surface 401f) may be reversed. By configuring the solder bulging portion 408d of the fraud detection contact portion 408 to bulge toward the element mounting surface 401e, the conductive fraudulent jig brought closer to the element mounting surface 401e side of the main control board 401 is fraudulent. The possibility of contact with the detection contact portion 408 can be increased.

A solder swelling region may be formed by adhering solder to the entire area of the GND line 405 formed on the element mounting surface 401e of the main control board 401. The solder swelling region bulges approximately 1 mm from the element mounting surface 401e. Thereby, when the conductive fraudulent jig is brought close to the element mounting surface 401e side, the possibility that the fraudulent jig comes into electrical contact with the GND line 405 through the solder swelling region can be increased.

A solder swelling region may be formed by adhering solder to the entire area of the fraud detection line 406 formed on the element mounting surface 401e of the main control board 401. The solder swelling region bulges approximately 1 mm from the element mounting surface 401e. As a result, when the conductive fraudulent jig is brought close to the element mounting surface 401e, the possibility that the fraudulent jig comes into electrical contact with the fraud detection line 406 through the solder swelling region can be increased.

Instead of the configuration in which both the solder bulging portion 407d of the GND contact portion 407 and the solder bulging portion 408d of the fraud detection contact portion 408 are provided on the solder surface 401f of the main control board 401, these 2 are provided on the solder surface 401f. A configuration may be configured in which only one of the types of solder bulging portions 407d and 408d is provided. In a configuration in which only the solder bulging portion 407d of the GND contact portion 407 is provided on the solder surface 401f, the fraud detection contact portion 408 is provided with the solder contact portion on the solder surface 401f. The solder contact portion is formed by allowing solder to flow into the through hole 408a of the fraud detection contact portion 408 from the solder surface 401f side, but does not bulge from the solder surface 401f and is formed on the solder surface 401f and the surface. It is one.

With the provided configuration, it is possible to grasp that a fraudulent act of bringing a conductive fraudulent jig closer to the solder surface 401f side has been performed.

<Fifth Embodiment>
The present embodiment is different from the fourth embodiment in that the pachinko machine 10 is provided with a configuration for monitoring fraudulent activity in a power-off state in which the supply of operating power to the pachinko machine 10 is stopped. Hereinafter, a configuration different from the fourth embodiment will be described. The description of the same configuration as that of the fourth embodiment is basically omitted.

FIG. 50 is an explanatory diagram for explaining an electrical configuration for monitoring fraudulent activity in a power-off state in the present embodiment.

Similar to the fourth embodiment, the element mounting surface 401e (FIG. 47 (a)) of the main control board 401 is provided with a GND line 405 and a fraud detection line 406. Further, on the solder surface 401f (FIG. 48 (a)) of the main control board 401, a large number of GND contact portions 407 electrically connected to the GND line 405 and a large number of electrical connections to the fraud detection line 406 are provided. The fraud detection contact unit 408 is provided. The main control board 401 in the present embodiment includes a MOSFET 421 that can switch between a state in which voltage is supplied to the fraud detection line 406 and a state in which voltage is not supplied, and a conductive fraudulent jig such as a flat-blade screwdriver in a power-off state. A fraud detection capacitor 422 is provided so that a fraudulent act can be grasped so as to bring the solder surface closer to the solder surface 401f. The MOSFET 421 and the fraud detection capacitor 422 are mounted on the element mounting surface 401e.

The MOSFET 421 includes a gate terminal 421a, a source terminal 421b, and a drain terminal 421c. In the MOSFET 421, a current flows between the source terminal 421b and the drain terminal 421c when the input voltage of the gate terminal 421a is in the HI state, and the source terminal is in the LOW state when the input voltage of the gate terminal 421a is in the LOW state. No current flows between the 421b and the drain terminal 421c.

The gate terminal 421a is electrically connected to the main CPU 64 by a copper wiring 423. The main CPU 64 controls the input voltage of the gate terminal 421a. The source terminal 421b is connected to the voltage supply pin 415 of the first connector CN41 that supplies voltage to the fraud detection line 406, and the drain terminal 421c is connected to the fraud detection line 406.

The fraud detection capacitor 422 includes a first terminal 422a and a second terminal 422b. The first terminal 422a is electrically connected to the wiring 425 connecting the fraud detection line 406 and the main CPU 64 by the copper wiring 424. The second terminal 422b is electrically connected to the GND line 405.

The main CPU 64 sets the input voltage of the gate terminal 421a to the HI state after the supply of the operating power to the pachinko machine 10 is started. As a result, the voltage is supplied to the fraud detection line 406, and the electric charge is accumulated in the first terminal 422a of the fraud detection capacitor 422. The main CPU 64 can grasp whether or not the electric charge is accumulated in the first terminal 422a based on the voltage of the wiring 425.

When the supply of operating power to the pachinko machine 10 is stopped and the power is cut off while the electric charge is accumulated in the first terminal 422a, the electric charge accumulated in the first terminal 422a is retained as it is. In the power cut-off state, one or more GND contact portions 407 and one are brought close to the solder surface 401f side of the main control board 401 from the side surface side of the main control device 60 by a conductive misuse jig such as a minus driver. When the fraud detection contact portion 408 is in contact with the above, the GND line 405 and the fraud detection line 406 are conducted. Further, in the power cut-off state, a conductive fraudulent jig such as a minus driver is brought closer to the element mounting surface 401e side of the main control board 401 from the side surface side or the front side of the main control device 60, and the GND line 405 and the fraudulent Even when the detection line 406 is in contact with the detection line 406, the GND line 405 and the fraud detection line 406 are electrically connected. When the fraud detection line 406 and the GND line 405 are conducted, the electric charge accumulated in the first terminal 422a escapes to the GND line 405. As a result, the electric charge is not accumulated in the first terminal 422a. When the supply of the operating power to the pachinko machine 10 is started, the main CPU 64 determines whether or not the electric charge is accumulated in the first terminal 422a, and when the electric charge is not accumulated in the first terminal 422a. Understand that fraudulent acts have been performed by bringing the fraudulent jig closer to the machine while the power is cut off.

Next, the power-on setting process executed by the main CPU 64 will be described with reference to the flowchart of FIG. The power-on setting process is executed in step S109 of the main process (FIG. 26).

In the power-on setting process, first, it is determined whether or not an electric charge is accumulated in the first terminal 422a of the fraud detection capacitor 422 (step S1001). When the electric charge is not accumulated in the first terminal 422a (step S1001: NO), it means that the electric charge accumulated in the first terminal 422a is lost in the power cutoff state. The process is executed (step S1002). In the abnormality notification process, the corresponding abnormality notification command is transmitted to the voice emission control device 70. When the voice emission control device 70 receives the abnormality notification command, the sound output control of the speaker unit 54, the light emission control of the display light emission unit 53, and the display control device 90 for notifying that an illegality in the power cut state is detected. To control. As a result, it is possible to grasp from the outside of the pachinko machine 10 that fraud in the power-off state has been detected. Further, in the abnormality notification process in step S1002, an abnormality signal is output to the management computer (not shown) of the game hall, which is an external device. As a result, it is possible for the management computer to grasp that fraud has been detected in the power-off state.

When the affirmative determination is made in step S1001 or the process of step S1002 is performed, the input voltage rise process for raising the input voltage of the gate terminal 421a from the LOW state to the HI state is performed (step S1003). As a result, the voltage is supplied to the fraud detection line 406, and the electric charge is accumulated in the first terminal 422a.

After that, an initial value setting process for setting a predetermined area of the main RAM 66 to the initial value, such as initialization of the power failure flag, is executed (step S1004), and a command corresponding to the current gaming state is executed in order to recognize the current gaming state. Is executed for the game state command transmission process (step S1005), and the power-on setting process is completed.

As described above, after the supply of the operating power is started, the main CPU 64 determines whether or not the electric charge is accumulated in the first terminal 422a before raising the input voltage of the gate terminal 421a to the HI state. This makes it possible to grasp the state of the first terminal 422a in the power cutoff state.

If it is determined in step S1001 that no electric charge is accumulated in the first terminal 422a, the input voltage of the gate terminal 421a is raised to the HI state after the abnormality notification process in step S1002 is executed. Therefore, when the supply of the operating power to the pachinko machine 10 is stopped after the abnormality notification process is executed and then the supply of the operating power is restarted, even though no fraudulent activity has been performed. It is prevented that the negative determination is made again in step S1001 and the abnormality notification process in step S1002 is executed.

According to the present embodiment described in detail above, the following excellent effects are obtained.

In the main control board 401, electric charges are accumulated in the first terminal 422a in a state where the operating power is being supplied to the pachinko machine 10, and the conductivity is inserted into the main control device 60 after the power is cut off. A fraud detection capacitor 422 is mounted, in which the electric charge accumulated in the first terminal 422a is lost when the fraud detection line 406 and the GND line 405 are conducted by the fraud jig. Therefore, it is possible to grasp the presence or absence of fraud in the power cutoff state by determining whether or not the electric charge is accumulated in the first terminal 422a after the supply of the operating power to the pachinko machine 10 is started. ..

When the main CPU 64 determines in step S1001 in the power-on setting process (FIG. 51) that the electric charge is not accumulated in the first terminal 422a of the fraud detection capacitor 422, the main CPU 64 executes the abnormality notification process. The manager of the game hall can grasp that the electric charge accumulated in the first terminal 422a has been lost due to the fraudulent act performed in the power-off state based on the execution of the abnormality notification process. ..

<Sixth Embodiment>
In this embodiment, the configuration of the main control board is different from that of the fourth embodiment. Hereinafter, a configuration different from the fourth embodiment will be described. The description of the same configuration as that of the fourth embodiment is basically omitted.

FIG. 52 (a) is a plan view showing the element mounting surface 431e of the main control board 431 according to the present embodiment, and FIG. 52 (b) is a plan view of the main control board 431 showing a part of the MPU 432 in an enlarged manner. 53 (a) is a plan view showing the back surface 431f of the main control board 431, and FIG. 53 (b) is a sectional view taken along line AA of FIG. 53 (a). Similar to the first embodiment, the main control board 431 is formed in a horizontally long rectangular shape, and as shown in FIG. 52 (a), a pair of upper and lower sides 431a and a lower side 431b and a pair of left and right left sides 431c are formed on the peripheral edges. And 431d on the right side. A large number of surface mount components such as MPU432, first to seventh connectors CN51 to CN57, and various elements are mounted on the main control board 431. These surface mount components are mounted only on the plate surface on one side of the main control board 431, and the plate surface is the element mounting surface 431e.

The MPU 432 and the first connector CN51 include terminals 441 to 443, 445 and 446 (FIGS. 52 (a) and 52 (b)) extending along the element mounting surface 431e of the main control board 431. Although not shown, surface mount components other than the MPU 432 and the first connector CN51 also have terminals extending along the element mounting surface 431e. Surface mount components including the MPU 432 and the first connector CN51 have terminals 441 to 443, 445 and 446 soldered to the element mounting surface 431e by surface mounting technology such as reflow soldering to the element mounting surface 431e side. It is implemented. In the present embodiment, the terminals 441 to 443, 445, 446 of the surface mount component exist only on the element mounting surface 431e side of the main control board 431, and do not exist on the back surface 431f side of the board. A wiring pattern (not shown) for electrically connecting terminals (not shown) of surface mount components is formed on the element mounting surface 431e.

As already described with reference to FIG. 7 in the first embodiment, the main control device 60 is mounted so that the surface of the front case body 121 faces the rear of the pachinko machine 10. In the installed state in the game hall, the element mounting surface 431e of the main control board 431 faces the rear of the pachinko machine 10, and the back surface of the board 431f faces the front of the pachinko machine 10. By opening the gaming machine main body 12 from the outer frame 11 to the front of the pachinko machine 10, the back side of the gaming machine main body 12 becomes visible. In this case, the main control device 60 constitutes the back portion of the gaming machine main body 12, and further, since the surface of the front case body 121 faces the rear of the pachinko machine 10 as described above, the gaming machine main body 12 is removed. By opening the frame 11 to the frame 11, the element mounting surface 431e of the main control board 431 becomes visible through the transparent front case body 121.

In the configuration in which the terminals 441 to 443, 445 and 446 of the surface mount component exist only on the element mounting surface 431e side of the main control board 431 as in the present embodiment, the illegal use of conductivity such as a minus driver is cured. There is a possibility that the jig may be inserted from the side surface side or the front surface side of the main control device 60 and brought into contact with the terminals 441 to 443, 445 and 446 existing on the element mounting surface 431e side. The configuration for detecting the fraud will be described.

As shown in FIG. 53 (a), the substrate back surface 431f of the main control board 431 is provided with a GND line 435 that goes around the peripheral edge of the substrate back surface 431f once, and the main control board is more than the GND line 435. A fraud detection line 436 that goes around the peripheral edge of the back surface 431f of the substrate is provided at a position closer to the center of the 431. The GND line 435 and the fraud detection line 436 are formed by etching a conductive metal foil (specifically, a copper foil).

The fraud detection line 436 is an electric wiring that makes it possible to grasp that a conductive fraud jig such as a minus driver has been inserted from the side surface side of the main control device 60 or the like. A fraud detection voltage (specifically, a + 5V voltage) is supplied to the fraud detection line 436. Similar to the fourth embodiment, the main CPU 64 monitors the voltage of the fraud detection line 436, and the fraud detection line 436 and the GND line 435 are conducted by a conductive fraud jig to conduct the fraud detection line 436. When it is known that the voltage of the device has dropped, it is possible to identify that the fraud has occurred.

The GND line 435 includes an upper GND line 435a that extends linearly along the upper side 431a of the main control board 431 from the left end to the right end of the upper side 431a with a predetermined width (specifically, a width of about 1.5 mm). A lower GND line 435b extending linearly with a predetermined width (specifically, a width of about 1.5 mm) from the left end to the right end of the lower side 431b along the lower side 431b of the control board 431, and the left side of the main control board 431. The left GND line 435c extending linearly with a predetermined width (specifically, a width of about 1.5 mm) from the upper end to the lower end of the left side 431c along 431c, and the right side along the right side 431d of the main control board 431. It is provided with a right side GND line 435d extending linearly with a predetermined width (specifically, a width of about 1.5 mm) from the upper end to the lower end of the 431d.

The fraud detection line 436 is provided with an upper fraud detection line 436a provided at a distance of approximately 1 mm downward from the upper GND line 435a and a lower side provided at a distance of approximately 1 mm upward from the lower GND line 435b. The fraud detection line 436b, the left fraud detection line 436c provided with an interval of approximately 1 mm to the right from the left GND line 435c, and the right side provided with an interval of approximately 1 mm to the left from the right GND line 435d. It is equipped with a fraud detection line 436d. The upper fraud detection line 436a extends linearly from the upper end of the left fraud detection line 436c to the upper end of the right fraud detection line 436d with a predetermined width (specifically, a width of about 1.5 mm), and the lower fraud detection line 436a has a predetermined width (specifically, a width of about 1.5 mm). The detection line 436b extends linearly from the lower end of the left fraud detection line 436c to the lower end of the right fraud detection line 436d with a predetermined width (specifically, a width of about 1.5 mm). The top, bottom, left, and right fraud detection lines 403a to 403d are electrically connected.

The peripheral edge of the back surface 431f of the substrate is doubly surrounded by the outer GND line 435 and the inner fraud detection line 436. The GND line 435 and the fraud detection line 436 are covered with an insulator resist (not shown) so as not to be exposed on the surface.

A large number of GND contact portions 437 are formed on the top, bottom, left, and right GND lines 435a to 435d so as to form one row in the extending direction of the GND lines 435a to 435d. As shown in FIG. 53 (b), the GND contact portion 437 penetrates the main control substrate 431 in the plate thickness direction, and its inner peripheral surface is plated with a conductive metal (specifically, copper). The through hole 437a is provided with lands 437b and 437c provided in a circle on the peripheral edge of the through hole 437a on the element mounting surface 431e and the substrate back surface 431f. The lands 437b and 437c are made of metal, specifically copper. The diameter of the through hole 437a is approximately 0.6 mm, and the diameter of the lands 437b and 437c is approximately 1.2 mm.

The GND contact portion 437 includes a solder bulging portion 437d that bulges approximately 1 mm from the element mounting surface 431e. The solder bulging portion 437d is formed by allowing solder to flow into the inside of the through hole 437a and the land 437b on the element mounting surface 431e side from the element mounting surface 431e side. The solder bulging portions 437d of all GND contact portions 437 are electrically connected to the GND line 435. Since the solder bulging portion 437d bulges from the element mounting surface 431e, the possibility that the conductive fraudulent jig brought close to the element mounting surface 431e comes into contact with the solder bulging portion 437d is increased. In the top, bottom, left, and right GND lines 435a to 435d, the GND contact portions 437 are provided at equal intervals so that the distance between the centers of the adjacent GND contact portions 437 is approximately 3 mm. As a result, the possibility that the conductive fraudulent jig brought close to the element mounting surface 431e comes into contact with the solder bulging portion 437d of any GND contact portion 437 is increased.

A large number of fraud detection contact portions 438 are formed on the top, bottom, left, and right fraud detection lines 436a to 436d so as to form one row in the extending direction of the fraud detection lines 436a to 436d. As shown in FIG. 53 (b), the fraud detection contact portion 438 penetrates the main control board 431 in the plate thickness direction, and its inner peripheral surface is plated with a conductive metal (specifically, copper). The through hole 438a is provided with lands 438b and 438c provided in a circle on the peripheral edge of the through hole 438a on the element mounting surface 431e and the substrate back surface 431f. The lands 438b and 438c are made of metal, specifically copper. The diameter of the through hole 438a is approximately 0.6 mm, and the diameter of the lands 438b and 438c is approximately 1.2 mm.

The fraud detection contact portion 438 includes a solder bulging portion 438d that bulges approximately 1 mm from the element mounting surface 431e. The solder bulging portion 438d is formed by allowing solder to flow into the inside of the through hole 438a and the land 438b on the element mounting surface 431e side from the element mounting surface 431e side. The solder bulging portions 438d of all fraud detection contact portions 438 are electrically connected to the fraud detection line 436. Since the solder bulging portion 438d bulges from the element mounting surface 431e, the possibility that the conductive fraudulent jig brought close to the element mounting surface 431e comes into contact with the solder bulging portion 438d is increased. In the up, down, left, and right fraud detection lines 436a to 436d, the fraud detection contact portions 438 are provided at equal intervals so that the distance between the centers of the adjacent fraud detection contact portions 438 is approximately 3 mm. As a result, the possibility that the conductive fraudulent jig brought close to the element mounting surface 431e comes into contact with the solder bulging portion 438d of any fraud detection contact portion 438 is increased.

The fraud detection line 436 is provided close to the GND line 435 on the back surface 431f of the substrate, and the fraud detection contact portion 438 and the GND contact portion 437 are close to each other on the element mounting surface 431e. As a result, when the conductive fraudulent jig is brought close to the element mounting surface 431e, one or more GND contact portions 437 and one or more fraud detection contact portions 438 are in contact with each other, resulting in a fraud detection line. The possibility that the voltage of 436 will drop is increased.

As shown in FIGS. 52 (a) and 52 (b), the MPU 432 is mounted near the center of the element mounting surface 431e of the main control board 431. The MPU 432 includes a large number of terminals 441 to 443 including a GND connection terminal 441 and a fraud detection connection terminal 442, and these terminals 441 to 443 are soldered on the element mounting surface 431e. As shown in FIG. 53A, a gap larger than the above-mentioned 3 mm gap between adjacent fraud detection contact portions 438 is provided near the center of the right side 431d of the back surface 431f of the substrate, and 1 is provided through the gap. A copper wiring 444 is formed that electrically connects the GND contact portion 437 and the GND connection terminal 441 of the MPU 432. The wiring 444 is covered with an insulator resist (not shown) so as not to be exposed on the surface.

As shown in FIG. 52A, the first connector CN51 is mounted on the upper side 431a side of the element mounting surface 431e of the main control board 431. The first connector CN51 includes a large number of terminals 445 and 446, and one of the large number of terminals 445 and 446 is a voltage supply terminal 445 (FIG. 53 (a)) that supplies voltage to the fraud detection line 436 (FIG. 53 (a)). 53 (a)). The numerous terminals 445 and 446, including the voltage supply terminal 445, are soldered on the element mounting surface 431e. As shown in FIG. 53A, one fraud detection contact portion 438 provided near the right side 431d of the main control board 431 and the fraud detection connection terminal 442 of the MPU 432 are electrically connected to the back surface 431f of the board. The copper wiring 447 is formed, and the copper wiring 447 provided in the vicinity of the upper side 431a of the main control board 431 is electrically connected to the voltage supply terminal 445 of the first connector CN51. Wiring 448 is formed. These wirings 447 and 448 are covered with an insulating resist (not shown) so as not to be exposed on the surface.

In a state where the operating power is being supplied to the pachinko machine 10, the fraud detection line 436 is connected to the fraud detection line 436 via the voltage supply terminal 445 of the first connector CN51 and the wiring 448 (specifically, the fraud detection voltage (specifically). + 5V voltage) is supplied, and the fraud detection voltage is supplied to the input side of the MPU 432 via the fraud detection line 436 and the fraud detection connection terminal 442. The main CPU 64 monitors the voltage supplied to the input side of the MPU 432 via the fraud detection connection terminal 442, and when the voltage is the fraud detection voltage, it can grasp that it is in a normal state. it can.

As described above, the GND contact portion 437 and the fraud detection contact portion 438 are close to each other on the element mounting surface 431e of the main control board 431. Therefore, a conductive fraudulent jig such as a minus driver is inserted from the side surface side or the front side of the main control device 60 to the element mounting surface 431e side and is in contact with the GND contact portion 437 and the fraud detection contact portion 438. When the state is reached, the GND line 435 and the fraud detection line 436 are conducted by the fraud jig. When the main CPU 64 monitors the voltage of the fraud detection line 436 and identifies that the GND line 435 and the fraud detection line 436 are conducted and the voltage of the fraud detection line 436 drops, an abnormality occurs in the fraud detection line 436. Know what happened.

According to the present embodiment described in detail above, the following excellent effects are obtained.

A GND line 435 and a fraud detection line 436 are provided on the back surface 431f of the main control board 431. The fraud detection line 436 is an electric wiring that makes it possible to grasp that a conductive fraud jig such as a minus driver has been inserted from the side surface side of the main control device 60 or the like. A fraud detection voltage is supplied to the fraud detection line 436. The main control board 431 is provided with a large number of GND contact portions 437 along the GND line 435, and is provided with a large number of fraud detection contact portions 438 along the fraud detection line 436. All GND contact parts 437 are electrically connected to the GND line 435, and all fraud detection contact parts 438 are electrically connected to the fraud detection line 436. The GND contact portion 437 and the fraud detection contact portion 438 include solder bulging portions 437d and 438d that bulge from the element mounting surface 401e. A conductive fraudulent jig is brought close to the element mounting surface 431e of the main control board 431, and the fraudulent jig is a solder bulging portion 437d and one or more fraud detection contact portions in one or more GND contact portions 437. When the solder bulging portion 438d in the 438 is in contact with both of the solder bulging portions 438d, the GND line 435 and the fraud detection line 436 are conductive. When the main CPU 64 monitors the voltage of the fraud detection line 436 and finds that the fraud detection line 436 and the GND line 435 are conducted by a conductive fraud jig and the voltage of the fraud detection line 436 drops. To identify that fraud has been committed. As a result, it is possible to detect an illegal act of inserting a conductive illegal jig on the element mounting surface 431e side of the main control board 431. On the element mounting surface 431e to which the terminals 441 to 443, 445, 446 of various electronic components are fixed by solder, a fraudulent act was performed in which a conductive fraudulent jig was brought into contact with the fixed portion by solder and its periphery. In this case, the signal transmitted from the various electronic components or the signal received by the various electronic components may be illegally changed. On the other hand, since the configuration is such that the fraudulent act of bringing the conductive fraudulent jig close to the element mounting surface 431e can be grasped, there is a possibility that the fraudulent act is performed without the manager of the game hall noticing. It has been reduced.

Since the solder swelling portion 437d of the GND contact portion 437 bulges from the substrate back surface 431f, the conductive fraudulent jig brought closer to the substrate back surface 431f side of the main control board 431 causes the solder swelling of the GND contact portion 437. The possibility of electrical contact with the portion 437d is increased.

Since the solder bulging portion 438d of the fraud detection contact portion 438 bulges from the substrate back surface 431f, the conductive fraudulent jig brought closer to the substrate back surface 431f side of the main control board 431 is soldered to the fraud detection contact portion 438. The possibility of electrical contact with the bulging portion 438d is increased.

On the element mounting surface 431e, the solder bulging portion 438d of the fraud detection contact portion 438 is arranged side by side with the solder bulging portion 437d of the GND contact portion 437. As a result, when the conductive fraudulent jig is brought closer to the element mounting surface 431e side, the fraudulent jig is the solder bulging portion 437d of the GND contact portion 437 and the solder bulging portion 438d of the fraud detection contact portion 438. It is more likely that you will be in contact with both of them. Therefore, there is an increased possibility that the fraud detection line 436 and the GND line 435 are conductive and the voltage of the fraud detection line 436 drops.

The solder bulging portion 437d of the GND contact portion 437 and the solder bulging portion 438d of the fraud detection contact portion 438 are provided intermittently along the peripheral edge portion of the element mounting surface 431e of the main control board 431. Therefore, when a fraudulent act is performed in which the conductive fraudulent jig approaches the element mounting surface 431e side of the main control board 431 from the side surface side of the main control device 60, the fraudulent jig is soldered to the GND contact portion 437. There is an increased possibility that the bulging portion 437d and the solder bulging portion 438d of the fraud detection contacting portion 438 are in contact with each other. As a result, the possibility that the GND line 435 and the fraud detection line 436 are conducted and the voltage of the fraud detection line 436 drops is increased. Therefore, the fraudulent activity can be grasped at an early stage.

Each of the solder bulging portion 437d of the GND contact portion 437 and the solder bulging portion 438d of the fraud detection contact portion 438 is provided over the entire circumference of the peripheral edge portion of the element mounting surface 431e of the main control board 431. Therefore, as compared with the configuration in which at least one of the solder bulging portion 437d of the GND contact portion 437 and the solder bulging portion 438d of the fraud detection contact portion 438 is provided only on a part of the peripheral edge portion of the element mounting surface 431e. When a conductive fraudulent jig approaches the element mounting surface 431e side of the main control board 431 from the side surface side of the main control device 60, the fraudulent jig causes solder swelling of the GND contact portion 437. There is an increased possibility that the solder bulging portion 438d of the portion 437d and the fraud detection contact portion 438 will be in contact with both portions.

The GND contact portion 437 is such that the distance between the centers of the adjacent GND contact portions 437 is approximately 3 mm along the upper GND line 435a, the lower GND line 435b, the left GND line 435c, and the right GND line 435d. It is provided at intervals. As a result, the possibility that the conductive fraudulent jig brought close to the element mounting surface 431e comes into contact with the solder bulging portion 437d of any GND contact portion 437 is increased.

In the fraud detection contact portion 438, the distance between the centers of adjacent fraud detection contact portions 438 along the upper fraud detection line 436a, the lower fraud detection line 436b, the left fraud detection line 436c, and the right fraud detection line 436d is approximately short. It is provided at equal intervals so as to be 3 mm. As a result, the possibility that the conductive fraudulent jig brought close to the element mounting surface 431e comes into contact with the solder bulging portion 438d of any fraud detection contact portion 438 is increased.

<Another form of the sixth embodiment>
-In the main control board 431, the wiring 444 that electrically connects one GND contact portion 437 and the GND connection terminal 441 of the MPU 432, one fraud detection contact portion 438, and the fraud detection connection terminal 442 of the MPU 432 are electrically connected. The plate surface on which the wiring 447 to be connected and the wiring 448 for electrically connecting one fraud detection contact portion 438 and the voltage supply terminal 445 of the first connector CN51 are formed is not limited to the element mounting surface 431e. Absent. A part or all of these wirings 444, 447, 448 may be formed on the back surface 431f of the substrate.

In the main control board 431, the GND line 435 may be provided on the element mounting surface 431e instead of the configuration in which the GND line 435 is provided on the back surface 431f of the board. In the GND line 435 provided on the element mounting surface 431e, the surface of the region other than the region where the GND contact portion 437 is provided is covered with a resist. The solder bulging portion 437d of the GND contact portion 437 is provided on the element mounting surface 431e side as in the sixth embodiment, and is a region other than the region where the GND contact portion 437 is provided in the GND line 435. It bulges about 1 mm from the resist covering the above. As a result, when the conductive fraudulent jig is brought close to the element mounting surface 431e side of the main control board 431, the possibility that the fraudulent jig comes into contact with the GND contact portion 437 is increased. As described above, even if the GND line 435 is provided on the element mounting surface 431e, the GND contact portion 437 can be brought into contact with the conductive fraudulent jig brought closer to the element mounting surface 431e side.

In the main control board 431, the fraud detection line 436 may be provided on the element mounting surface 431e instead of the fraud detection line 436 provided on the back surface 431f of the board. In the fraud detection line 436 provided on the element mounting surface 431e, the surface of a region other than the region where the fraud detection contact portion 438 is provided is covered with a resist. The solder bulging portion 438d of the fraud detection contact portion 438 is provided on the element mounting surface 431e side as in the sixth embodiment, and is an area where the fraud detection contact portion 438 is provided in the fraud detection line 436. It bulges approximately 1 mm from the resist covering a region other than the above. As a result, when the conductive fraudulent jig is brought close to the element mounting surface 431e side of the main control board 431, the possibility that the fraudulent jig comes into contact with the fraud detection contact portion 438 is increased. As described above, even if the fraud detection line 436 is provided on the element mounting surface 431e, the fraud detection contact portion 438 can be brought into contact with the conductive fraudulent jig brought closer to the element mounting surface 431e.

Instead of the configuration in which both the solder bulging portion 437d of the GND contact portion 437 and the solder bulging portion 438d of the fraud detection contact portion 438 are provided on the element mounting surface 431e of the main control board 431, the element mounting surface 431e A configuration may be configured in which only one of these two types of solder bulging portions 437d and 438d is provided. In a configuration in which only the solder bulging portion 437d of the GND contact portion 437 is provided on the element mounting surface 431e, the fraud detection contact portion 438 is provided with the solder contact portion on the element mounting surface 431e. The solder contact portion is formed by allowing solder to flow into the through hole 438a of the fraud detection contact portion 438 from the element mounting surface 431e side, but does not bulge from the element mounting surface 431e and the element mounting surface. It is flush with 431e. The solder contact portion is exposed, and the conductive fraudulent jig is brought closer to the element mounting surface 431e side and comes into contact with both the solder bulging portion 437d of the GND contact portion 437 and the solder contact portion of the fraud detection contact portion 438. In this state, the GND line 435 and the fraud detection line 436 are conducted by the fraudulent jig. Further, in the configuration in which only the solder bulging portion 438d of the fraud detection contact portion 438 is provided on the element mounting surface 431e, the GND contact portion 437 is provided with the solder contact portion on the element mounting surface 431e. The solder contact portion is formed by allowing solder to flow into the through hole 437a of the GND contact portion 437 from the element mounting surface 431e side, but does not bulge from the element mounting surface 431e and the element mounting surface 431e. It is flush with each other. The solder contact portion is exposed, and the conductive fraudulent jig is brought close to the element mounting surface 431e side and comes into contact with both the solder contact portion of the GND contact portion 437 and the solder bulge portion 438d of the fraud detection contact portion 438. In this state, the GND line 435 and the fraud detection line 436 are conducted by the fraudulent jig. As described above, even if only one of the solder bulging portion 437d of the GND contact portion 437 and the solder bulging portion 438d of the fraud detection contact portion 438 is provided on the element mounting surface 431e, the solder contact portion is provided on the other. With the configuration provided with the above, it is possible to grasp that a fraudulent act of bringing a conductive fraudulent jig closer to the element mounting surface 431e side has been performed.

<7th Embodiment>
In the present embodiment, the configuration for executing the power failure monitoring process when the supply of the operating power to the pachinko machine 10 is stopped is different from that of the first embodiment. Hereinafter, a configuration different from the first embodiment will be described. The description of the same configuration as that of the first embodiment is basically omitted.

FIG. 54 (a) is a plan view showing the element mounting surface 451 a of the main control board 451 according to the present embodiment, and FIG. 54 (b) is a plan view of the main control board 451 enlarged near the center.

Similar to the fourth embodiment, the main control board 451 is mounted with a large number of through-hole mounting components such as the MPU 452, the first to seventh connectors CN61 to CN67, and various elements. These through-hole mounting components are mounted only on the plate surface on one side of the main control board 451, and the plate surface is the element mounting surface 451a.

The through-hole mounting component includes a pin (not shown) that extends linearly in the plate thickness direction of the main control board 451. The insert-mounting component is mounted by being soldered by an insertion-mounting technique such as flow soldering with the pin inserted through a through-hole (not shown) provided by penetrating the main control board 451 in the plate thickness direction. Has been done. The plate surface of the main control board 451 opposite to the element mounting surface 451a is a solder surface to which the pins of the through-hole mounting components are soldered.

On the element mounting surface 451a, a connector group mounting area 453 on which the first to fourth connectors CN61 to CN64 are mounted and a fifth to seventh connector mounting area on which the fifth to seventh connectors CN65 to CN67 are mounted. 454 to 456 and an element mounting area 457 on which a large number of elements are mounted are provided.

An MPU 452 is mounted near the center of the element mounting area 457, and a power failure monitoring device 461 is mounted between the MPU 452 and the connector group mounting area 453 in the element mounting area 457. The power failure monitoring device 461 has a power supply voltage terminal 461a in which a power supply voltage of + 36V (DC36V) is input from the power supply / emission control device 78 via the first connector CN61, and a power supply / emission control device 78 via the first connector CN61. It is provided with a drive voltage terminal 461b to which an element drive voltage of DC5V is input, a reset signal terminal 461c for transmitting a reset signal to the MPU 452, and a power failure signal terminal 461d for transmitting a power failure signal to the MPU 452. Note that in FIGS. 54 (a) and 54 (b), the wiring connecting the first connector CN61 and the power failure monitoring device 461 is not shown.

The MPU 452 includes a reset signal receiving terminal 462 that receives a reset signal and a power failure signal receiving terminal 463 that receives a power failure signal. On the solder surface of the main control board 451 opposite to the element mounting surface 451a, a reset signal wiring 464 for electrically connecting the reset signal terminal 461c and the reset signal receiving terminal 462, and a power failure signal terminal 461d A power failure signal wiring 465 that electrically connects the power failure signal receiving terminal 463 and the power failure signal receiving terminal 463 is formed. The reset signal wiring 464 and the power failure signal wiring 465 are copper wiring patterns, and are covered with an insulator resist so as not to be exposed on the surface.

The power failure monitoring device 461 monitors the power supply voltage input from the power supply / emission control device 78, and when the power supply voltage drops below the power failure reference voltage of + 24V (DC24V), the operating power to the pachinko machine 10 is increased. Identify that the supply will be stopped. When the power failure monitoring device 461 determines that the supply of operating power is stopped, the power failure monitoring device 461 lowers the power failure signal output to the MPU 452 from the HI state to the LOW state. The main CPU 64 grasps that the supply of the operating power to the pachinko machine 10 is stopped by detecting the fall of the power failure signal from the HI state to the LOW state, and similarly to the first embodiment described above. The power failure information storage process (step S201 in the timer interrupt process (FIG. 27)) executes the power failure processing.

The power failure monitoring device 461 lowers the reset signal from the HI state to the LOW state after a predetermined time (specifically, 9 milliseconds later) after the power failure signal is turned off. The operation of the main CPU 64 is stopped when the reset signal falls. In order to execute the power failure processing, the element drive voltage supplied to the MPU 452 needs to be maintained at + 5V (DC5V) until the power failure processing is completed. In the present embodiment, the power failure reference voltage is set to 24V so that sufficient time for executing the power failure processing can be secured. The power failure reference voltage is not limited to + 24V and is arbitrary as long as sufficient time can be secured to execute the power failure processing.

<Power failure information storage processing>
Next, the power failure information storage process executed by the main CPU 64 will be described with reference to the flowchart of FIG. 55. The power failure information storage process is executed in step S201 of the timer interrupt process (FIG. 27).

In the power failure information storage process, first, it is determined whether or not a fall of the power failure signal received from the power failure monitoring device 461 from the HI state to the LOW state is detected (step S1101), and the fall of the power failure signal is detected. If not (step S1101: NO), the power failure information storage process is terminated as it is.

On the other hand, when the fall of the power failure signal is detected (step S1101: YES), the power failure processing (process of steps S1102 to S1104) is executed. Specifically, first, the checksum of the main RAM 66 is calculated (step S1102), and the calculated checksum is saved (step S1103). After that, "1" is set in the power failure flag provided in the main RAM 66 (step S1104), and the power failure information storage process is completed. The power failure flag is a flag for the main CPU 64 to grasp that the power failure processing (processes in steps S1102 to S1104) has been normally executed when the supply of operating power to the main CPU 64 is stopped. is there.

Next, a state in which the power failure processing is executed will be described with reference to the time charts of FIGS. 56 (a) to 56 (g). FIG. 56A shows a period during which power failure processing is executed by the main CPU 64, and FIG. 56B shows a power supply voltage input from the power supply / emission control device 78 to the power failure monitoring device 461. FIG. 56B. (C) shows the element drive voltage input from the power supply / emission control device 78 to the power failure monitoring device 461, FIG. 56 (d) shows the state of the power failure signal, and FIG. 56 (e) shows the state of the reset signal. 56 (f) shows the timing when the supply of the operating power to the pachinko machine 10 is started, and FIG. 56 (g) shows the timing when the supply of the operating power to the pachinko machine 10 is stopped.

As shown in FIG. 56 (f), when the supply of the operating power is started at the timing of t1, as shown in FIGS. 56 (b) and 56 (c), the power supply / emission control device is at the timing of t1. The power supply voltage and the element drive voltage input to the power failure monitoring device 461 from 78 start to rise. After that, as shown in FIG. 56 (c), when the element drive voltage input from the power supply / emission control device 78 to the power failure monitoring device 461 at the timing of t2 reaches the voltage (+ 5 V) in the normal operating range, FIG. 56 ( As shown in d), the power failure monitoring device 461 raises the power failure signal from the LOW state to the HI state at the timing of t2.

After that, as shown in FIG. 56B, the power supply voltage input from the power supply / emission control device 78 to the power failure monitoring device 461 reaches + 36V (DC36V) at the timing of t3. After that, at the timing of t4 when a predetermined time (specifically, 9 milliseconds) has elapsed from the timing of t2, the power failure monitoring device 461 raises the reset signal from the LOW state to the HI state as shown in FIG. 56 (e). .. The main CPU 64 starts operation when the reset signal is activated.

The time from the timing of t2 when the power failure monitoring device 461 raises the power failure signal to the timing of t4 when the power failure signal is raised is a predetermined time sufficient to stabilize the element drive voltage supplied to the MPU 452 at + 5V (DC5V). Specifically, it is set to 9 milliseconds). As a result, the operation of the main CPU 64 can be started after the MPU 452 is in a state where the element drive voltage of + 5V (DC5V) can be stably supplied.

After that, as shown in FIG. 56 (g), when the supply of the operating power is stopped at the timing of t5, it is input from the power supply / emission control device 78 to the power failure monitoring device 461 as shown in FIG. 56 (b). The power supply voltage starts to drop from + 36V (DC36V) and becomes below the power failure reference voltage (specifically, + 24V) at the timing of t6. As shown in FIG. 56 (d), the power failure monitoring device 461 lowers the power failure signal from the HI state to the LOW state at the timing of t6.

After that, as shown in FIG. 56A, the main CPU 64 detects the fall of the power failure signal in the power failure information storage process (FIG. 55) performed at the timing of t7, and also performs the power failure processing (power failure information). The processing of steps S1102 to S1104 in the storage process (FIG. 55) is started. The power failure processing ends at the timing of t8.

During the period from the timing of t7 to the timing of t8 when the power failure processing is executed, the HI state of the reset signal is maintained as shown in FIG. 56 (e), and the power supply is maintained as shown in FIG. 56 (c). The element drive voltage input from the launch control device 78 to the power failure monitoring device 461 is maintained at a normal voltage (specifically, + 5V). As a result, the processing at the time of power failure can be completed before the operation of the main CPU 64 is stopped, and when the supply of the operating power to the pachinko machine 10 is started, the game starts from the state before the supply of the operating power is stopped. Can be restarted normally.

After that, as shown in FIG. 56 (e), a power failure occurs at the timing of t9, which is later than the timing of t8 and the timing at which a predetermined time (specifically, 9 milliseconds) has elapsed from the timing of t6. The monitoring device 461 lowers the reset signal from the HI state to the LOW state. As a result, the operation of the main CPU 64 is stopped. After that, as shown in FIG. 56 (c), the element drive voltage input from the power supply / emission control device 78 to the power failure monitoring device 461 starts to drop at the timing of t10.

As described above, the operation of the main CPU 64 is stopped because a sufficient period is secured for executing the power failure processing as the period from the power failure signal being shut down to the reset signal being shut down. It is possible to complete the power failure processing at a timing earlier than that.

Next, a configuration for reducing the influence of radiation noise on the reset signal wiring 464 connecting the power failure monitoring device 461 and the MPU 452 will be described.

As described above, the operation of the main CPU 64 is stopped when the reset signal drops from the HI state to the LOW state. Therefore, when only the reset signal falls due to the influence of noise without the power failure signal falling in advance, the power failure processing (the processing of steps S1102 to S1104 in the power failure information storage process (FIG. 55)) is executed. The operation of the main CPU 64 stops without being performed. In this case, since "1" is not set in the power failure flag in the main RAM 66, a negative determination is made in step S105 of the main process (FIG. 26), and the main RAM 66 is cleared (step S108). Further, when the power failure signal drops from the HI state to the LOW state, the power failure processing is executed. Therefore, when the power failure signal drops due to the influence of noise, the power failure processing is unnecessarily executed.

As described above, the reset signal wiring 464 and the power failure signal wiring 465 are formed on the solder surface which is the plate surface on the main control board 451 opposite to the element mounting surface 451a. Further, as already described with reference to FIG. 7 in the first embodiment, the main control device 60 is mounted so that the surface of the front case body 121 faces the rear of the pachinko machine 10. In the state where the pachinko machine 10 is installed in the island equipment, the element mounting surface 451a of the main control board 451 faces the rear of the pachinko machine 10. The game ball replenishment route for sequentially replenishing the game balls from the island equipment to the tank 75 (FIG. 2) in the payout mechanism unit 73 exists behind the pachinko machine 10 with respect to the main control board 451. In the game ball replenishment route, static electricity is generated due to the game balls rubbing against each other or the friction between the game balls and the ball passage. Then, radiation noise is generated when this static electricity is suddenly discharged. As described above, the reset signal wiring 464 and the power failure signal wiring 465 are provided on the side opposite to the game ball replenishment path with the main control board 451 interposed therebetween. As a result, the possibility that the reset signal and the power failure signal are affected by the radiation noise generated by the game ball replenishment path is reduced.

As shown in FIGS. 54 (a) and 54 (b), the element mounting surface 451a of the main control board 451 is provided with a noise countermeasure solid 466 for reducing the influence of radiation noise on the reset signal and the power failure signal. ing. The noise suppression solid 466 is a metal (specifically, copper) solid pattern coated with an insulator resist, and is electrically connected to a ground plane (not shown) of the main control board 451. The noise countermeasure solid 466 is formed by etching a metal foil (specifically, a copper foil). The noise countermeasure solid 466 is located on the element mounting surface 451a of the main control board 451 at a position corresponding to the reset signal wiring 464 and the power failure signal wiring 465 formed on the solder surface of the main control board 451. , 465 is provided so as to be wider than these signal wirings 464 and 465 along these signal wirings 464 and 465 in such a manner that a noise countermeasure solid 466 exists between substantially the entire area and the game ball replenishment path. Has been done.

The noise countermeasure solid 466 exists between the game ball replenishment path for sequentially replenishing the game ball to the tank 75 (FIG. 2) in the payout mechanism unit 73 from the island equipment, and the reset signal wiring 464 and the power failure signal wiring 465. doing. The electrical noise generated in the game ball replenishment path is applied to the noise countermeasure solid 466 existing in front of the reset signal wiring 464 and the power failure signal wiring 465 when viewed from the noise source (game ball replenishment path). It is absorbed and escapes to the ground plane (not shown) of the main control board 451. As a result, it is possible to reduce the possibility that the influence of the electrical noise generated in the game ball replenishment path affects the reset signal and the power failure signal.

In a configuration in which the reset signal wiring 464 and the power failure signal wiring 465 are provided on the opposite sides of the main control board 451 from the game ball replenishment path, the reset signal wiring 464 and the power failure signal wiring 465 and the game ball replenishment path By further providing a metal noise countermeasure solid 466 in between, the ability to shield the radiant noise generated in the game ball replenishment path is enhanced, and the influence of the radiant noise on the reset signal and the power failure signal is affected. It can be further reduced.

According to the present embodiment described in detail above, the following excellent effects are obtained.

A metal noise countermeasure solid 466 is provided between the reset signal wiring 464 and the power failure signal wiring 465 and the game ball replenishment path for replenishing the game ball to the tank 75. The electrical noise generated in the game ball replenishment path is caused by the noise countermeasure solid 466 existing in front of the reset signal wiring 464 and the power failure signal wiring 465 when viewed from the noise source (game ball replenishment path). Be absorbed. As a result, it is possible to reduce the possibility that the influence of the electrical noise generated in the game ball replenishment path affects the reset signal and the power failure signal.

By reducing the possibility that the reset signal will fall due to the influence of radiation noise, the power failure signal will not fall in advance and only the reset signal will fall due to the influence of radiation noise, resulting in power failure processing (power failure processing ( It is prevented that the operation of the main CPU 64 is stopped without executing the process of step S1102 to step S1104 in the power failure information storage process (FIG. 55). Further, since the possibility that the power failure signal falls due to the influence of radiation noise is reduced, it is prevented that the power failure processing is unnecessarily executed.

The noise suppression solid 466 is a solid pattern made of metal (specifically, copper), and is electrically connected to the ground plane of the main control board 451. Noise Countermeasures The electrical noise absorbed by the solid 466 escapes to the ground plane. As a result, the possibility that the electrical noise generated in the game ball replenishment path is absorbed by the noise countermeasure solid 466 can be increased, and the possibility that the influence of the noise affects the reset signal and the power failure signal is reduced. can do.

The noise countermeasure solid 466 is such that the reset signal wiring 464 and the power failure signal wiring 465 face the game ball replenishment path with the noise countermeasure solid 466 in between, and these signal wirings are arranged along these signal wirings 464 and 465. It is provided so as to be wider than 464 and 465. As a result, the possibility that the electrical noise generated in the game ball replenishment path reaches the reset signal wiring 464 and the power failure signal wiring 465 without being absorbed by the noise countermeasure solid 466 is reduced. Therefore, the influence of radiation noise on the reset signal and the power failure signal can be reduced.

The MPU 452 and the power failure monitoring device 461 are through-hole mounting components, and the MPU 452 and the power failure monitoring device 461 are mounted on the element mounting surface 451a of the main control board 451. The terminals 462 and 463 of the MPU 452 and the terminals 461a to 461d of the power failure monitoring device 461 are soldered on the main control board 451 on the solder surface which is the plate surface opposite to the element mounting surface 451a. Therefore, in the main control board 451, the entire reset signal wiring 464 for the power failure monitoring device 461 to transmit the reset signal to the main control board 451 and the power failure signal wiring 465 for transmitting the power failure signal are provided on the solder surface. In addition, noise countermeasure solid 466 may be provided on the element mounting surface 451a of the main control board 451 in a region opposite to the entire reset signal wiring 464 and the power failure signal wiring 465 with the main control board 451 sandwiched between them. it can. As a result, before the electrical noise generated on the opposite side of the reset signal wiring 464 and the power failure signal wiring 465 with the noise countermeasure solid 466 sandwiched between them reaches the reset signal wiring 464 and the power failure signal wiring 465, the noise is generated. The noise can be blocked by the noise countermeasure solid 466 existing in front of the reset signal wiring 464 and the power failure signal wiring 465 when viewed from the source (game ball replenishment path).

The reset signal wiring 464 and the power failure signal wiring 465 are provided on the side opposite to the game ball replenishment path with the main control board 451 interposed therebetween. As a result, the possibility that the reset signal and the power failure signal are affected by the radiation noise generated in the game ball replenishment path is reduced.

The power failure monitoring device 461 is mounted on the main control board 451 on which the MPU 452 is mounted. Therefore, the total length of the reset signal wiring 464 can be shortened and the total length of the power failure signal wiring 465 can be shortened as compared with the configuration in which the power failure monitoring device 461 is mounted on a board different from the MPU 452. .. As a result, the influence of radiation noise on the reset signal and the power failure signal is reduced.

If the operation of the main CPU 64 is stopped without executing the power failure processing, the main RAM 66 is cleared after the supply of the operating power to the pachinko machine 10 is started. As a result, when the operation of the main CPU 64 is not normally stopped, it is possible to prevent the game from being performed while the information stored in the main RAM 66 is maintained.

<Other Embodiments>
It should be noted that the description is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the spirit of the present invention. For example, it may be changed as follows. Incidentally, the following configuration of another embodiment may be applied individually or in combination to the configuration of the above embodiment.

(1) In the first embodiment, instead of the configuration in which the main control board 61 is fixed to the back case body 122, the main control board 61 may be fixed to the front case body 121. The front side facing plate portion 141 of the front case body 121 is used for position adjustment when the main control board 61 is combined with the front case body 121 at the four corners (upper left side, lower left side, lower right side and upper right side) of the element facing surface 141a. The substrate position adjustment boss used is integrally formed. The substrate position adjusting boss is formed in a cylindrical shape so as to project from the element facing surface 141a toward the back side facing plate portion 123.

(8) In the first to third embodiments, when a fraudulent act of illegally manipulating a signal is performed, a signal having a relatively large number of game balls to be paid out is preferentially protected from the fraudulent act. While assigned to the terminal 115 on one end side of the fourth connector CN4, the signal on which the number of game balls to be paid out when the fraudulent act is performed is relatively small is the terminal on the other end side of the fourth connector CN4. It may be the configuration assigned to 116. As already described in the first to third embodiments, the terminal 115 on one end side of the fourth connector CN4 is brought into contact with a conductive fraudulent jig as compared with the terminal 116 on the other end side to illegally signal. Priority is given to protection from fraudulent operations. Since the number of the terminal 115 on the one end side of the fourth connector CN4 is limited, the number of signals assigned to the terminal 115 on the one end side is also limited.

In this configuration, the detection signals of the first to third winning opening detection sensors 42a to 44a and the detection signals of the special electric detection sensor 45a are assigned to the terminal 115 on one end side, while the detection signal of the gate detection sensor 49a is on the other end side. It is assigned to terminal 116. As already described in the first embodiment, even if a ball enters the through gate 35, the game ball is not paid out. On the other hand, when a ball enters the general winning opening 31, 10 prize balls are paid out, and when a ball enters the special electric winning device 32, 15 prize balls are paid out. Is paid out. For this reason, when a fraudulent act of illegally manipulating the detection signals of the first to third prize opening detection sensors 42a to 44a is performed continuously as if a ball was entered into the general winning opening 31, 10 pieces are used. The prize balls are paid out continuously. Further, when a fraudulent act of illegally manipulating the detection signal of the special electric power detection sensor 45a is performed continuously as if a ball has entered the special electric power winning device 32, 15 prize balls are continuously paid out. Will be done. In these cases, the economic loss that the game hall suffers in a short time becomes large.

By assigning a detection signal to which a relatively large number of game balls (for example, 10 or more game balls) are paid out when the signal is illegally operated to the terminal 115 on one end side of the fourth connector CN4, the game hole is shortened. It is possible to prevent fraudulent activities that cost a lot of time.

Terminals 113 to 115 are preferentially protected from fraudulent acts of illegally manipulating the signal in the 2nd to 4th connectors CN2 to CN4 only for the signal regarding the presence or absence of the game ball entering the ball entry portion where It may be the configuration assigned to. As signals regarding the presence or absence of a game ball entering the ball entry portion, the first to third winning opening detection sensors 42a to 44a, the special electric detection sensor 45a, the first operation port detection sensor 46a, the second operation port detection sensor 47a, The detection signals of the out port detection sensor 48a and the gate detection sensor 49a are present.

In this configuration, among these detection signals, the detection signals of the first operation port detection sensor 46a, the second operation port detection sensor 47a, and the gate detection sensor 49a, which are related to the transition to a state advantageous for the player, are fraudulent acts. It is assigned to terminals 113 to 115 that are preferentially protected from. On the other hand, the detection signals of the first to third winning opening detection sensors 42a to 44a, the special electric detection sensor 45a, and the out opening detection sensor 48a, which are not related to the transition to the advantageous state for the player, are the terminals on the other end side of the fourth connector CN4. It is assigned to 116. The other end terminal 116 is not a target to be preferentially protected from fraudulent activity.

As already described in the first embodiment, the winning lottery is performed with the winning of the first operating port 33 or the second operating port 34 as a trigger. If a big hit or a small win is won in the winning lottery based on the winning of the first operating port 33, the mode shifts to the open / close execution mode. In addition, even if a big hit or a small hit is won in the winning lottery based on the winning of the second operating port 34, the mode shifts to the open / close execution mode. The opening / closing execution mode is a game mode in which the special electric winning device 32 can be won, which is advantageous for the player. As already described in the first embodiment, the internal lottery is performed with the winning of the through gate 35 as a trigger. Then, when the result of the internal lottery is the electric service opening winning, the stop result corresponding to the result is displayed, and the variable display of the general drawing display unit 38a is completed, the state shifts to the general electric opening state. The general electric power open state is a state in which the general electric power accessory 34a is in the open state in a predetermined mode and the second operating port 34 can be won a prize, which is advantageous for the player.

Among the signals regarding the presence or absence of the game ball entering the ball entry section, the transition to a state advantageous for the player occurs due to the entry of the game ball. By configuring the configuration in which only the presence / absence signal is assigned to the terminals 113 to 115 which are preferentially protected from fraudulent acts of illegally manipulating the signal in the second to fourth connectors CN2 to CN4, the signal is illegal. It is possible to prevent the player from being illegally created in a favorable state by the fraudulent act of manipulating the player.

The normal electric drive signal may be assigned to the terminal 115 on one end side of the fourth connector CN4, and the special electric open detection sensor 32b and the general electric open detection sensor 34b may not be provided.

If the special electric drive signal is illegally transmitted to the special electric drive unit 32c, the special electric winning device 32 is illegally opened, so that the special electric winning device 32 is illegally won. I will be forced to. In the configuration in which the special electric opening detection sensor 32b is not provided, the main CPU 64 cannot grasp the situation in which the special electric winning device 32 is illegally won. If a fraudulent act of illegally transmitting a special electric drive signal to the general electric drive unit 34c is performed, the general electric accessory 34a is illegally opened, so a prize is given to the second operating port 34. It will be generated illegally. In the configuration in which the normal power opening detection sensor 34b is not provided, the main CPU 64 cannot grasp the situation in which the winning of the second operating port 34 is illegally generated.

On the other hand, by configuring the special electric drive signal and the general electric drive signal to be assigned to the terminal 115 on one end side of the fourth connector CN4, a fraudulent act of illegally manipulating the special electric drive signal and the general electric drive signal can be performed. Can be prevented. In this configuration, only one of the special electric drive signal and the general electric drive signal is assigned to the terminal 115 on one end side of the fourth connector CN4, and the other is assigned to the terminal 116 on the other end side. May be.

Due to the peripheral edge of the variable display unit projecting forward of the pachinko machine 10 from the surface of the game board 24, the areas where the game ball can flow down in the game area PA are the upper area and the upper area. On the other hand, it is divided into a left side region and a right side region which are continuous below the left side region, and a lower region which is continuous below the left side region and the right side region, respectively. The game ball flows down in the order of the upper region → the left side region → the lower region when the launch operation device 28 is operated with the rotation amount in the first range, and the upper side when the launch operation device 28 is operated with the rotation amount in the second range. It flows down in the order of area → right area → lower area.

In the lower region, a first operating portion is provided so that a prize can be won only when the game ball flows down the left region of the left region and the right region. A second actuating portion having a guidance unit is provided in the right region. The game ball flowing down the right region does not enter the second operating portion when the guiding unit is in the non-inducing state, while it enters the second operating portion when the guiding unit is in the guided state.

A winning device is provided. The game ball that has won the through winning section can win the second operating section, the special electric winning device, or the distribution winning device. The through winning unit, the special electric winning device, and the distribution winning device can win a prize only when the game ball flows down the right side region of the left side region and the right side region. When a predetermined number of game balls are paid out when the first operating unit, the second operating unit, the distribution winning device, and the special electric winning device are hit, it is assumed that the through winning section is hit. However, the payout of the game ball is not executed. When a lottery is performed triggered by winning a prize in the through winning unit and the result of the lottery is a winning in the guidance execution state, the guidance unit of the second operating unit enters the guidance execution state in a predetermined mode. Transition.

A winning lottery is held based on the winning of the first operating unit or the second operating unit. When either the 6R jackpot result or the 15R jackpot result is selected in the winning lottery, the mode shifts to the open / close execution mode in which the special electric winning device can be won after the game times corresponding to the jackpot result are completed. .. If any of the first small hit result to the third small hit result is selected in the winning lottery executed based on the winning of the second operating unit, after the game round corresponding to the small hit result is completed, The mode shifts to the distribution execution mode in which the distribution prize device can be won. The distribution winning device is provided with a distribution entrance having a size that allows the game ball to pass through, and is in a closed state in which the game ball cannot pass through the distribution entrance and an open state in which the game ball can pass through. It is equipped with a distribution side opening / closing member for switching. The game ball that has won a prize at the distribution entrance is led out to a branch passage formed in the base body of the distribution winning device. The branch passage includes an upstream passage region, a discharge passage region set to be continuous with the downstream end of the upstream passage region, and a discharge passage region branched from an intermediate position of the discharge passage region.

At the branching point to the V winning passage area in the discharge passage area, a switching piece is provided which is arranged at the retracted position in the first state and is arranged at the V induction position in the second state. The game ball that has flowed into the branch passage in the first state flows down the discharge passage region without being guided to the V winning passage region, and is detected by a count detection sensor provided downstream from the branch position by the switching piece. In the second state, the game ball that has flowed into the branch passage is guided by the switching piece and flows into the V winning passage area, and is detected by the V winning detection sensor provided in the V winning passage area. In the distribution execution mode, the game ball is basically detected by the V winning detection sensor.

Regardless of whether the game ball is detected by the count detection sensor or the game ball is detected by the V prize detection sensor, the same number of prize balls corresponding to the distribution winning device are paid out. Further, when the game ball is detected by the V winning detection sensor in the distribution execution mode, the open / close execution mode is generated after the distribution execution mode. On the other hand, if the distribution execution mode ends without the game ball being detected by the V winning detection sensor, the opening / closing execution mode does not occur.

The connectors CN5 to CN7 are inserted into the 5th to 7th connector insertion holes 374 to 376. After that, the main control board 61 is manually slid upward with respect to the front case body 312 and the connector-compatible plate 314 until the board position adjusting boss abuts on the upper end of the board fixing boss. As a result, the lower peripheral edges 362b to 365b of the first to fourth front side connector insertion holes 362 to 365 are in a state of approaching the lower upright wall portions 101c to 104c of the first to fourth connectors CN1 to CN4. ..

The front side facing plate portion 351 has a columnar front side board fixing boss used for fixing the main control board 61 to the front case body 312 on the left upper part, the left lower part, the right side lower part, and the right side upper part of the element facing surface 351a. It is integrally formed. The front board fixing boss projects from the element facing surface 351a toward the main control board 61, and a screw hole for screw fixing the main control board 61 is formed at the free end of the front board fixing boss. Substrate fixing through holes are formed in the upper left side, the lower left side, the lower right side, and the upper right side of the main control board 61 so that the main control board 61 can be screwed to the front board fixing boss.

(16) In the fourth to fifth embodiments, a power supply line for supplying operating power to the main CPU 64 may be provided instead of the fraud detection line 406. The GND line 405 and the power supply line are provided close to the element mounting surface 401e of the main control board 401. Therefore, in a state where the operating power is supplied to the main CPU 64 through the power supply line, a conductive fraudulent jig such as a minus driver is inserted into the element mounting surface 401e side of the main control board 401, and the fraudulent activity When the GND line 405 and the power supply line are conducted by the jig, a state in which the operating power is not supplied to the main CPU 64 is created. As a result, the operation of the main CPU 64 is stopped.

The solder surface 401f of the main control board 401 is provided with a large number of power supply contact parts instead of the large number of fraud detection contact parts 408. The power supply contact portion includes a solder bulging portion that bulges approximately 1 mm from the solder surface 401f. All power supply contacts are electrically connected to the power supply line. Since the solder bulging portion of the power supply contact portion bulges from the solder surface 401f, the possibility of contact with the fraudulent jig when the fraudulent jig is brought closer to the solder surface 401f side is increased. There is. While operating power is being supplied to the main CPU 64 through the power supply line, a conductive fraudulent jig such as a minus driver is inserted into the solder surface 401f side of the main control board 401 to make one or more GND contacts. When the 407 and one or more power supply contact portions are in contact with each other, a state is created in which the GND line 405 and the power supply line are conducted so that the main CPU 64 is not supplied with operating power. As a result, the operation of the main CPU 64 is stopped.

As described above, the main control is provided by providing the power supply line on the element mounting surface 401e of the main control board 401 and providing the solder bulging portion of the power supply contact portion on the solder surface 401f. The operation of the main CPU 64 can be stopped when the fraudulent jig is brought close to the element mounting surface 401e side or the soldering surface 401f side of the substrate 401. As a result, it is possible to prevent the game from proceeding in a state where fraud using a fraud jig is performed.

(17) In the fourth to fifth embodiments, the combination of the GND line 405 and the GND contact portion 407 and the fraud detection line 406 and the fraud detection contact portion 408 is different from the peripheral portion of the main control board 401. It may be the configuration provided in. For example, a combination of the GND line 405 and the GND contact portion 407 and the fraud detection line 406 and the fraud detection contact portion 408 may be provided around the MPU 402. Specifically, on the element mounting surface 401e, a GND line having a width of about 1.5 mm is provided around the MPU 402 at a predetermined distance (for example, a distance of about 2 mm) from the pins 411 to 413 of the MPU 402. At the same time, fraud detection lines having a width of about 1.5 mm are arranged side by side on the GND line at a predetermined distance (specifically, a distance of about 1 mm) from the GND line on the opposite side of the MPU 402. The GND line and the fraud detection line are provided so as to surround the entire circumference of the MPU 402. The GND line and the fraud detection line may be provided only in a part around the MPU 402.

The surfaces of the GND line and the fraud detection line are not covered with the resist and are exposed. Therefore, if a conductive fraudulent jig such as a flat-blade driver is inserted into the element mounting surface 401e side of the main control board 401 to bring it into contact with the MPU 402, the fraudulent jig causes the GND line. And the fraud detection line are in a conductive state, and the voltage of the fraud detection line drops. Similar to the fourth embodiment, the main CPU 64 monitors the voltage of the fraud detection line, and when it is found that a voltage drop has occurred, the main control board 401 is provided with a conductive fraudulent jig. Identify that a fraudulent activity has been committed.

The solder surface 401f of the main control board 401 has a predetermined distance (for example, between the centers of adjacent GND contact portions) along the GND line provided on the element mounting surface 401e, which is the plate surface opposite to the solder surface 401f. A plurality of GND contact portions are provided at intervals (distances such that the distance is approximately 3 mm). Similar to the fourth embodiment, the GND contact portion penetrates the main control board 401 in the plate thickness direction and its inner peripheral surface is plated with a conductive metal (specifically, copper). It includes a through hole, a land circularly provided on the peripheral edge of the through hole on the element mounting surface 401e and the solder surface 401f, and a solder bulging portion bulging from the solder surface 401f. All GND contacts are electrically connected to the GND line by through holes. The solder bulging portion bulges approximately 1 mm from the solder surface 401f, and when a conductive fraudulent jig such as a minus driver is brought close to the solder surface 401f, the fraudulent jig comes into contact with the solder bulging portion. The possibility is increasing.

The solder surface 401f of the main control board 401 has a predetermined interval (for example, the center of an adjacent fraud detection contact portion) along the fraud detection line provided on the element mounting surface 401e which is the plate surface opposite to the solder surface 401f. A plurality of fraud detection contact portions are provided at intervals (intervals such that the distance between them is approximately 3 mm). Similar to the fourth embodiment, the fraud detection contact portion penetrates the main control board 401 in the plate thickness direction and its inner peripheral surface is plated with a conductive metal (specifically, copper). It is provided with a through hole, a land provided in a circle on the peripheral edge of the through hole on the element mounting surface 401e and the solder surface 401f, and a solder bulging portion bulging from the solder surface 401f. All fraud detection contacts are electrically connected to the fraud detection line by through holes. The solder bulging portion bulges approximately 1 mm from the solder surface 401f, and when a conductive fraudulent jig such as a minus driver is brought close to the solder surface 401f, the fraudulent jig comes into contact with the solder bulging portion. The possibility is increasing.

The wiring pattern for electrically connecting the MPU 402 and other through-hole mounting components mounted on the main control board 401 is formed on the solder surface 401f through the gap between the GND contact portion and the fraud detection contact portion. If a fraudulent act is performed in which a conductive fraudulent jig is inserted into the solder surface 401f side of the main control board 401 to bring it into contact with the pins 411 to 413 of the MPU 402, the fraudulent jig is used for the GND contact part and fraud. By being in contact with both of the detection contact portions, the GND line and the fraud detection line are in a conductive state, and the voltage of the fraud detection line drops. As a result, it is possible to identify that the main CPU 64 has performed a fraudulent act of bringing the conductive fraudulent jig close to the main control board 401.

In this way, the main control board 401 is mounted on the main control board 401 by forming a combination of the GND line and the GND contact portion and the fraud detection line and the fraud detection contact portion around the MPU 402. Among the through-hole mounting parts, it is possible to grasp the fraudulent act of bringing the conductive fraudulent jig closer to the MPU 402. In addition to the configuration of the fourth embodiment in which the combination of the GND line 405 and the GND contact portion 407 and the fraud detection line 406 and the fraud detection contact portion 408 is provided around the main control board 401, the present invention As in the configuration, a combination of the GND line and the GND contact portion and the fraud detection line and the fraud detection contact portion may be provided around the MPU 402.

(18) In the fourth to sixth embodiments, instead of the configuration in which the main CPU 64 monitors the voltage of the fraud detection line 406 (the fraud detection line 436 in the sixth embodiment), the main CPU 64 detects fraud. It may be configured to monitor the current flowing through the line 406. In this configuration, in a state where the operating power is supplied to the pachinko machine 10, a current of, for example, 5 mA flows through the fraud detection line 406 as a fraud detection current. When the GND line 405 (GND line 435 in the sixth embodiment) and the fraud detection line 406 are conducted by a conductive fraudulent jig such as a flat-blade driver, the amount of current flowing through the fraud detection line 406 is used as a reference. A state in which the amount of current is reduced to less than 2.5 mA (for example, 2.5 mA) or a state in which no current is flowing through the fraud detection line 406 occurs. The main CPU 64 monitors the current flowing through the fraud detection line 406, and the amount of current flowing through the fraud detection line 406 is less than the reference current amount, or no current is flowing through the fraud detection line 406. When the occurrence of the state is grasped, it is identified that the fraudulent act using the conductive fraudulent jig has been performed. In this way, even if the main CPU 64 monitors the current flowing through the fraud detection line 406, it is possible to detect fraudulent acts in which the conductive fraudulent jig is brought close to the main control board 61.

(19) In the fourth to sixth embodiments, the GND line 405 is replaced with the configuration provided on the entire circumference of the main control board 401 (the main control board 431 in the sixth embodiment). May be configured to be provided only on a part of the peripheral edge of the main control board 401. For example, the GND line and the right GND line are provided on the left and right peripheral edges of the main control board 401 formed in a horizontally long rectangle, while the GND lines are provided on the upper and lower peripheral edges of the main control board 401. It may be configured without.

The left fraud detection line is provided at a distance of approximately 1 mm to the right from the left GND line, and the right fraud detection line is provided at a distance of approximately 1 mm to the left from the right GND line. The left fraud detection line and the right fraud detection line have a predetermined width (specifically, a width of about 1.5 mm) and extend linearly in the vertical direction from the upper end to the lower end of the main control board 401.

As described above, GND lines are not provided on the upper and lower peripheral edges of the main control board 401. Therefore, fraud detection lines can be provided near the upper side 401a and the lower side 401b of the main control board 401. The upper fraud detection line has a predetermined width (approximately 1.5 mm width) along the upper side 401a (upper side 431a in the sixth embodiment) of the main control board 401, and is from the upper end of the left fraud detection line to the right fraud detection line. It extends linearly to the upper end in the left-right direction. Further, the lower fraud detection line has a predetermined width (approximately 1.5 mm width) along the lower side 401b (lower side 431b in the sixth embodiment) of the main control board 401, and is fraudulent from the lower end of the left fraud detection line to the right side. It extends linearly to the lower end of the detection line in the left-right direction. These fraud detection lines on the top, bottom, left, and right are electrically connected.

In a configuration in which the vertical dimension of the main control board 401 is smaller than the horizontal dimension, a GND line and a fraud detection line are provided on the left and right peripheral edges of the main control board 401, while the upper and lower sides of the main control board 401 are provided.

It exists on the rotation tip side of 13. When a fraudulent act such as inserting a conductive fraudulent jig such as a minus driver from the side surface of the main control device 60 to bring it closer to the main control boards 401 and 431 without removing the main control device 60 from the inner frame 13 is performed. If an unauthorized jig is inserted from the rotation base end side of the frame 13 (right side 401d, 431d side of the main control boards 401, 431), the other directions (upper sides 401a, 431a side of the main control boards 401, 431) are to be inserted. , The lower side 401b, 431b side, or the left side 401c, 431c side), as compared with the case where the fraudulent jig is inserted, it becomes necessary to open the inner frame 13 greatly with respect to the outer frame 11. Therefore, the fraudulent act of inserting the fraudulent jig from the side surface of the main control boards 401 and 431 to bring it closer to the main control boards 401 and 431 is the upper side 401a and 431a side and the lower side 401b and 431b side of the main control boards 401 and 431. , Or there is a high possibility that it will be performed from the left side 401c, 431c side.

In this configuration, GND lines and fraud detection lines are provided on the upper peripheral edge, lower peripheral edge, and right peripheral edge of the main control boards 401 and 431, while the right peripheral edge of the main control boards 401 and 431 is provided.

The upper GND line extends linearly along the upper sides 401a and 431a of the main control boards 401 and 431 from the left end to the right end of the upper sides 401a and 431a with a predetermined width (specifically, a width of approximately 1.5 mm). The lower GND line is linearly aligned with the lower sides 401b and 431b of the main control board 401 from the left end to the right end of the lower sides 401b and 431b with a predetermined width (specifically, a width of about 1.5 mm). It is postponed. Further, the left GND line extends linearly along the left sides 401c and 431c of the main control boards 401 and 431 from the upper end to the lower end of the left sides 401c and 431c with a predetermined width (specifically, a width of approximately 1.5 mm).

The upper fraud detection line is provided at a distance of approximately 1 mm below the upper GND line, and the lower fraud detection line is provided at a distance of approximately 1 mm above the lower GND line. Further, the left fraud detection line is provided at a distance of approximately 1 mm to the right from the left GND line. As described above, the GND line is not provided on the right peripheral edge of the main control board 61. Therefore, the fraud detection line can be provided in the vicinity of the right sides 401d and 431d of the main control boards 401 and 431. The right fraud detection line has a predetermined width (approximately 1.5 mm width) along the right sides 401d and 431d of the main control board 401, and is linear in the vertical direction from the right end of the upper fraud detection line to the right end of the lower fraud detection line.

These fraud detection lines on the top, bottom, left, and right are electrically connected.

Only the fraud detection line is provided on the right peripheral edge of the main control boards 401 and 431, and the GND line is not provided. Therefore, the GND line and the fraud detection line are provided on the right peripheral edge of the main control boards 401 and 431. Compared with the above configuration, the area on which the through-hole mount components or the surface mount components can be mounted on the main control boards 401 and 431 is expanded in the left-right direction of the main control boards 401 and 431.

As described above, in the configuration in which the right sides 401d and 431d of the main control boards 401 and 431 are the rotation base ends of the inner frame 13 and the left sides 401c and 431c are the rotation tip sides of the inner frame 13.

A wide area on which mounting components can be mounted can be secured.

(21) In the fourth to sixth embodiments, the GND lines 405 and 435 and the GND contact portions 407 and 437 of the main control boards 401 and 431 are more than the fraud detection lines 406 and 436 and the fraud detection contact portions 408 and 438. Instead of the configuration provided on the outer peripheral side, the fraud detection lines 406, 436 and the fraud detection contact parts 408, 438 are on the outer peripheral side of the main control boards 401, 431 rather than the GND lines 405, 435 and the GND contact parts 407, 437.

All power supply contacts are electrically connected to the power supply line. The power supply contact portion includes a solder bulging portion that bulges approximately 1 mm from the solder surface 401f. All power supply contacts are electrically connected to the power supply line. Since the solder bulging portion of the power supply contact portion bulges from the solder surface 401f, the possibility of contact with the fraudulent jig when the fraudulent jig is brought closer to the element mounting surface 431e is increased. ing. While operating power is being supplied to the main CPU 64 through the power supply line, a conductive fraudulent jig such as a minus driver is inserted into the element mounting surface 431e side of the main control board 431 to make one or more GND contacts. When the unit 437 and one or more power supply contact portions are in contact with each other, a state is created in which the GND line 435 and the power supply line are conducted so that the main CPU 64 is not supplied with operating power.
