Below the medal selector 100 is connected a cancel chute 150 (FIG. 2) for paying out medals determined to be illegal medals and medals discharged from the medal hopper 21 to the medal payout exit 20.

As shown in FIGS. 4 and 5, the base plate portion 110 has a guide passage 130c for guiding the medals discharged from the medal outlet portion 115 of the medal selector 100 to the medal hopper 21 (FIG. 3). The guide 130 is connected and fixed.

A medal entrance 112 for receiving medals inserted from the medal insertion slot 12 is provided at the upstream end of the base plate 110, and medals inserted into the medal selector 100 from the medal entrance 112 are transferred to the medal rails 111. It is guided along the downstream end. A select plate 113 for guiding a regular-sized medal to the downstream side of the medal rail 111 is arranged at a substantially intermediate position of the medal rail 111. A medal pusher 114, which is pushed downward by a passing medal, is arranged at a surface position of the medal rail 111 where the select plate 113 is arranged.

The select plate 113 and the medal pusher 114 are configured to push the medal into the cancel shooter 140 by the medal pusher 114 without guiding the medal by the select plate 113 when the inserted medal is smaller than the regular standard size. (See medal M2 in FIG. 6). If the inserted medal is a proper medal (regular medal), the medal is guided along the select plate 113 (see medal M1 in FIG. 6), and the medal pressure 114 is pushed in while the medal rail 111 is on the downstream side. Will be guided to.

Normally, the select plate 113 is positioned at the medal guide position, but under certain conditions (for example, when a specified number of medals are inserted, when an error occurs, when a game is started, etc.), the select plate 113 displays After moving to the ejection position, the medals inserted from the medal insertion slot 21 are forcibly ejected to the cancel shooter 140. Further, a magnet is arranged on the medal rail 111 (not shown), and the medals attracted to this magnet are discharged to the cancel shooter 140 as nonstandard medals (illegal medals).

[Medal ejection guide (game media ejection part)]
Embodiments 1 to 3 of the medal discharge guide 130 according to the present invention will be described below with reference to FIGS. 4, 5, 8 and 9.

(Example 1)
The medal discharge guide 130 according to the first embodiment will be described with reference to FIGS. 4 and 8.
<Structure>
As shown in FIG. 4, the medal discharge guide 130 according to the first embodiment is fixedly or integrally connected to the base plate portion 110 of the medal selector 100. The medal discharge guide 130 is curved downwardly and has a recessed guide passage 130c formed between an outer wall 130a and an inner wall 130b of the medal discharge guide 130.

The entrance side of the medal discharge guide 130 communicates with the medal exit section 115 of the medal selector 100, and the exit side is arranged above the medal hopper 21.

The width of the recessed guide passage 130c is designed to be larger than the width of the medal so that the medal discharged from the medal selector 100 can pass smoothly, and the heights of the outer wall 130a and the inner wall 130b are also different. The height is designed so as not to deviate from the guide passage 130c.

The inner wall 130b of the medal ejection guide 130 is provided with a second medal sensor 132 which is a reflective or transmissive optical sensor for detecting passage of a medal. In the present embodiment (Examples 1 to 3), the second medal sensor 132 constitutes a second game medium detecting means for detecting the game medium which is the medal ejected from the medal ejection guide.

In the present embodiment, the second medal sensor 132 is provided at a height position such that its detection light is incident on the central portion of the medal passing through the guide passage 130c.

Although the example of FIG. 4 shows an example in which the second medal sensor 132 is provided on the exit side of the guide passage 132c, the invention is not limited to this, and it may be provided on the central portion or the entrance side. Further, the second medal sensor 132 may be provided on the outer wall 130a instead of the inner wall 130b.

<Action>
In the medal ejection guide 130 according to the first embodiment configured as described above, the medals ejected from the medal exit portion 115 of the medal selector 100 are guided in a concave shape that is curved and inclined downward from the entrance side of the medal ejection guide 130. It passes through the passage 130c and is finally discharged from the exit side to the medal hopper 21.

The second medal sensor 132 detects passage of the medal while the medal passes through the guide passage 130c of the medal ejection guide 130.

In the first embodiment, as shown in FIG. 8, the second medal sensor 132 outputs an ON signal when a medal is detected and outputs an OFF signal when the medal is not detected.

By the way, as described above, the width of the guide passage 130c is larger than the thickness of the medal, and the guide passage 130 is curved as shown in FIG. Therefore, the second medal sensor 132 according to the first embodiment is not limited to the case where the medals alone pass, but the number of medals to be passed is not only when the medals pass by themselves but also when the two or three medals pass through the second medal sensor 132. Can be counted.

Hereinafter, a method of counting medals passing through the guide passage 130c of the medal discharge guide 130 according to the first embodiment will be described with reference to FIGS. In the following description, an example in which two medals pass through in an overlapping manner will be described, but it is possible to count even when three or more medals overlap.

FIG. 8A shows a case where the medals pass by themselves, FIG. 8B shows a case where the medals pass by overlapping (low overlapping degree), and FIG. 8C shows a case where medals pass by overlapping (the overlapping degree). In the schematic diagram of the (high) medal and the on/off output diagram of the second medal sensor 132, the broken line in the center indicates the position where the detection light of the second medal sensor 132 is incident on the medal. It is incident on the approximate center of the medal.

As a precondition, each medal moves at the same speed when passing the second medal sensor 132 in the guide passage 130c. Also, it has been experimentally confirmed that when one unit (single) medal passes through the second medal sensor 132, the unit detection duration is about 33 to 34 msec.

(1) Example of Single Passage As shown in FIG. 8(a), the second medal sensor 132 emits detection light to the substantially central portion of the medal, so the on state continues until the diameter portion of the medal passes.

In the first embodiment, the number of medals is counted as one when the second medal sensor 132 changes from the off state to the on state in order to simplify the control element and reduce the control load. However, the present invention is not limited to this, and for example, when the ON duration is 0.8 times or more and less than 1.3 times the unit detection duration, it may be counted as one sheet.

(2) Example of overlapping passage (high overlap and low overlap)
As shown in FIGS. 8B and 8C, the ON state continues for a longer time than in the case of the single passage of (1) (unit detection duration time).

In the first embodiment, when the ON duration is about 42.5 ms (about 1.3 times the unit detection duration), the number of passed medals is counted as two.

In the following, it is possible to count the number of medals passing by overlapping three or more by a similar method. However, when the degree of overlap is high, for example, three medals may be erroneously counted as two medals, but since such erroneous counting is considered to occur infrequently, it is processed as a counting error.

In addition, when the ON duration is a certain time or longer (for example, when the ON duration is 100 msec or more), it is possible to treat the medal as being clogged.

In the first embodiment, the regular interrupt processing time of the main control circuit 71 is used to detect the ON/OFF detection duration of the second medal sensor 132 without using a timer. As a result, it is possible to reduce the number of parts and the control load. Details of the specific counting process flow performed by the main control circuit 71 will be described later (FIG. 15).

<Effect>
As described above, according to the first embodiment, by measuring and analyzing the ON duration of the second medal sensor 132, it is possible to determine whether one or more medals have passed. It can count with high accuracy. Further, since the regular interrupt processing by the existing main control circuit is used without preparing a new timer device or the like for counting the duration, it is possible to reduce the number of parts and the control load.

(Example 2)
The medal discharge guide 130 according to the second embodiment will be described with reference to FIGS. 5 and 9.
<Structure>
In the second embodiment, two second medal sensors 132a and 132b are provided in the height direction of the inner wall 130b of the guide passage, as shown in FIG. 5, in order to reduce erroneous counting.

The two second medal sensors 132b are arranged at a predetermined interval in the height direction of the inner wall 130b, and the second medal sensor 132a has a second medal sensor 132b so that the detection light of the second medal sensor 132a enters the medal at a substantially central portion. Is provided on the inner wall 130b so that the detection light is incident on the top of the medal. In the present embodiment (Example 2), the second medal sensors 132a and 132b constitute a plurality of detection devices of the second game medium detecting means for detecting the game medium which is the medal ejected from the medal ejection guide.

<Action>
9(a) to 9(c) show on/off output diagrams of the two second medal sensors 132a and 132b in the second embodiment configured as described above.

The on/off diagram of the second medal sensor 132a is the same as that of the first embodiment, but when the degree of overlap of medals is high, the second medal sensor 132b has an on duration longer than 132a as shown in FIG. 9B. short. Further, when the degree of overlapping of medals is low, an off state occurs between the medals at the upper part of the medals, so that an on/off diagram as shown in FIG. 9C is obtained.

Therefore, by comparing the on/off durations of the second medal sensors 132a and 132b, the number of passed medals can be more accurately counted. That is, by adding the second medal sensor 132b, it is possible to accurately determine and count the overlapping of two or more medals.

As described above, in the second embodiment, the number of medals passing through by overlapping two or more medals can be more accurately counted by using the two second medal sensors 132a and 132b.

In the above description, the example in which the second medal sensor 132b is arranged so that the detection light of the second medal sensor 132b is incident on the upper part of the medal has been described, but it may be arranged so as to be incident on the lower part of the medal. Also, a plurality of second medal sensors 132b may be arranged so as to enter both the upper part and the lower part.

<Effect>
As described above, according to the second embodiment, by measuring and analyzing the on-duration times of the plurality of second medal sensors 132a and 132b, it is possible to more reliably determine the passage of one or more medals. Therefore, the number of medals can be counted with high accuracy. Further, since the regular interrupt processing by the existing main control circuit is used without preparing a new timer device or the like for counting the duration, it is possible to reduce the number of parts and the control load.

(Example 3)
The number of medals passing through the medal ejection guide 130 is counted by the second medal sensor 132 based on the method described in the first and second embodiments. In the third embodiment, the method described in the first embodiment is used. Based on the comparison process between the count value detected by the second medal sensor 132 and the count value detected by the first medal sensor 120, the number-of-medals-checking process for determining the presence or absence of fraud or clogging of medals will be described.

In the medal number check process of the third embodiment, the number of medals detected by the first medal sensor 120 provided in the medal selector 100 and counted by the first medal counter is divided into three ranges in order to reduce the control load. That is, it is divided into three ranges of 1 to 4, 5 to 14, and 15 or more, and the allowable difference number (0, 2, 3 in the third embodiment) is defined for each. ..

Then, in each range, the number of medals detected by the second medal sensor 132 and compared with the number of medals counted by the second medal counter are compared. If the difference is less than or equal to the allowable difference number, it is determined to be normal, and if the allowable difference number is exceeded. It is determined that an error such as fraudulent activity or clogging of medals has occurred, and error processing is executed.

According to the third embodiment, the number of medals is counted by the second medal sensor 132 to determine whether the medals have passed or passed, so that the number of medals passing through the medal ejection guide 130 can be counted with higher accuracy. You can Therefore, the presence/absence of abnormality can be determined more accurately, and the frequency of erroneous determination and false alarm can be reduced.
As a result, the reliability and operating rate of the gaming machine can be improved.

In the third embodiment, the number of medals detected by the first medal sensor 120 and counted by the first medal counter is divided into three ranges for determination, but the present invention is not limited to this. The number of sheets can be changed appropriately. Further, the allowable difference number may be a certain ratio of the number of coins detected by the first medal sensor 120 and counted by the first medal counter, for example, about 20% or less, without dividing the number of medals into a plurality of ranges.
Details of this medal number check processing flow will be described later (FIG. 16).

[Configuration of main CPU]
FIG. 10 shows a main CPU (main control circuit, control unit) 71 that controls the operation of the gaming machine 1, peripheral devices (actuators, etc.) electrically connected to the main CPU 71, and control signals transmitted from the main CPU 71. A circuit configuration including the liquid crystal display device 160, the speakers 6L and 96, the LEDs 151, and the sub control circuit 72 that controls the lamps 152 based on the above is shown.

The main CPU 71 has a microcomputer 30 arranged on a circuit board as a main component, and a circuit for extracting a random value is added to this. The microcomputer 30 includes a CPU 31, a ROM 32, and a RAM 33.

The main CPU 71 executes a program stored in the ROM 32 to perform processing relating to the progress of the game and directly or indirectly control the operation of each actuator. The main CPU 71 includes a clock pulse generation circuit 34 and a frequency divider 35 that generate a reference clock pulse, a random number generator 36 that generates a random number, and a sampling circuit 37 that extracts a random number value from the generated random number. Are connected. The main CPU 71 may be configured to generate a random number and extract a random number value. In that case, the random number generator 36 and the sampling circuit 37 can be omitted, but they may be left for preliminary use.

The ROM 32 stores programs executed by the main CPU 71 (FIG. 11 etc.) and fixed data. In the ROM 32, for example, an internal lottery table (not shown) for determining an internal lottery combination based on the extracted random number value, and a display combination expected storage area for determining a reel stop mode according to a stop operation (Not shown) and the like are stored. In addition, various control signals and the like to be transmitted to the sub control circuit 72 are stored. It should be noted that commands and information are not transmitted from the sub control circuit 72 to the main CPU 71, and one-way communication is performed from the main CPU 71 to the sub control circuit 72.

The RAM 33 is used to temporarily store data when the main CPU 71 executes a program. The RAM 33 stores, for example, an internal lottery combination, information on the current gaming state, and the like.

In FIG. 10, the main actuators whose operation is controlled by a control signal from the microcomputer 30 include a BET lamp (1-BET lamp 7a, 2-BET lamp 7b, maximum BET lamp 7c) and a bonus number display section 8 , A credit display section 9, a display section such as a payout number display section 10 and the like, a hopper 21 for storing medals and paying out a predetermined number of medals according to a command from the hopper drive circuit 41, and stepping for rotating the reels 3L, 3C, 3R. There are motors 49L, 49C, 49R.

Further, a motor drive circuit 39 for controlling the rotation operation of the stepping motors 49L, 49C, 49R by outputting a pulse (for example, an excitation signal) to the stepping motors 49L, 49C, 49R, and a hopper drive circuit for controlling the operation of the hopper 21. 41, a lamp drive circuit 45 for controlling lighting and extinguishing of the BET lamps 7a, 7b, 7c, and a display unit (that is, a bonus bonus number display unit 8, a credit display unit 9, a payout number display unit 10, etc.). The display drive circuit 48 is connected to the main CPU 71. Each of these drive circuits receives a control signal output from the main CPU 71 and controls the operation of each actuator.

The start switch 17S, the stop switches 18LS, 18CS, 18RS, the 1-BET switches 13S, 2- are provided as means for generating an input signal that is transmitted to the microcomputer 30 to generate a control signal. There are a BET switch 14S, a maximum BET switch 15S, a settlement (C/P) switch 16S, a reel position detection circuit 50, a payout completion signal circuit 51, a first medal sensor 120, a second medal sensor 132, and the like.

The start switch 17S detects an operation in which the start lever 17 is tilted, and outputs a game start command signal for commanding the start of the game. The stop switches 18LS, 18CS, 18RS generate stop command signals for instructing the stop of the fluctuation of the symbols in response to the operation of the corresponding stop buttons 18L, 18C, 18R.

The reel position detection circuit 50 receives a pulse from a reel rotation sensor provided on the reels 3L, 3C, 3R and supplies a signal for detecting the rotation position of each reel 3L, 3C, 3R to the main CPU 71. The payout completion signal circuit 51 pays out medals when the total number of medals detected by the payout medal detection unit 218 (that is, the number of medals paid out from the payout mechanism 212 of the medal hopper 21) reaches a specified value. Generate a signal to detect completion.

The main CPU 71 causes the first medal sensor 120 to count the number of medals determined to be normal by the medal selector 100 as described above. Further, the main CPU 71 causes the second medal sensor 132 to count the number of medals passing through the medal ejection guide 130 as described above.

Further, the main CPU 71 detects the medals passing through the medal ejection guide 130 by the second medal sensor 132 and counts them by the second medal counter, and the main CPU 71 counts them by the first medal counter and the second medal counter by the signal thereof. By checking the consistency of the number of medals that have been played, it is checked whether fraud has occurred or whether an abnormality such as clogging has occurred. The details will be described later.

In the circuit of FIG. 10, the random number generator 36 generates a random number belonging to a certain numerical range, and the sampling circuit 37 is generated by the random number generator 36 at an appropriate timing after the operation of tilting the start lever 17. Extract one random value from the random numbers. The random number value thus extracted is stored in the random number storage area provided in the RAM 33, and for determining the internal lottery combination, etc. based on an internal lottery table (not shown) stored in the ROM 32, for example. Referenced.

The reels 3L, 3C, 3R basically make one rotation by outputting a pulse (that is, an excitation signal) to the stepping motors 49L, 49C, 49R a predetermined number of times (for example, 336 times). The number of pulses output to each of the stepping motors 49L, 49C, 49R is written in a predetermined area of the RAM 33 as a pulse count value.

On the other hand, a reset pulse is obtained from the reels 3L, 3C, 3R every one rotation. When this reset pulse is input to the main CPU 71 via the reel position detection circuit 50, the count value of the pulse stored in the RAM 33 is updated to "0". As a result, the pulse count value corresponds to the rotation position within the range of one rotation for each reel 3L, 3C, 3R.

The symbol arrangement table stored in the ROM 32 is used for associating the rotational positions of the reels 3L, 3C, 3R with the symbols drawn on the reel outer peripheral surface. In this symbol arrangement table, the rotation position at which the reset pulse is generated is used as a reference (reference position), which corresponds to each of the code numbers and code numbers sequentially given at constant rotation pitches of the reels 3L, 3C, 3R. It is associated with a design code that is information indicating the design.

Further, in the ROM 32, a symbol combination table (not shown) is stored. This symbol combination table is given to the player and the player after the stop of all reels 3L, 3C, 3R when controlling the rotation of the left reel 3L, the center reel 3C, and the right reel 3R. It is referred to for determining a profit (for example, the number of paid out medals).

When the internal lottery combination is determined by the internal lottery process described later based on the extraction of the random number value, the main CPU 71 causes the stop switches 18LS, 18CS, 18RS to operate at the timing when the player operates the stop buttons 18L, 18C, 18R. A signal for controlling the rotation of the reels 3L, 3C, 3R is sent to the motor drive circuit 39 based on the input signal sent, the determined stop table (not shown), and the like.

When the combination of symbols corresponding to the small winning combination is displayed along the activated line, the main CPU 71 supplies a payout command signal to the hopper drive circuit 41 to pay out a predetermined number of medals from the payout mechanism 212 of the medal hopper 21. To do. At that time, the payout completion signal circuit 51 counts the number of medals paid out from the payout mechanism 212, and when the counted value reaches the designated number, inputs the medal payout completion signal to the main CPU 71. As a result, the main CPU 71 stops driving the payout mechanism 212 via the hopper drive circuit 41 and ends the medal payout process.

Further, the gaming machine 1 is provided with an operation unit for adjusting the volume of the pedestal 11 or for displaying game information as a means for generating an input signal transmitted to the sub control circuit 72. (Not shown). This operation unit can be operated by an employee, a player, or the like in the game hall, and adjusts the volume output from the speakers 6L and 6R, for example. The sub-control circuit 72 controls the sound output from the speakers 6L and 6R to a volume corresponding to the transmitted input signal based on the input signal from the operation unit.

[Control flow of main CPU (main control circuit)]
A control flow performed by the main CPU 71 (main control circuit) will be described with reference to FIG. 11.

First, the main CPU 71 performs initialization processing (S1). Specifically, the main CPU 71 initializes the storage content of the RAM 33.

Then, the main CPU 71 causes the designated storage area in the RAM 33 (for example, information on a storage area for storing information on the internal lottery combination, the value of the medal passing timer described later, the values of the first and second medal counters, etc.). Is erased (that is, cleared) (S2). Specifically, the main CPU 71 erases data in a predetermined area of the RAM 33 used in the previous game.

In S3, the main CPU 71 executes a bonus operation monitoring process, and then executes a process of S4. In this bonus operation monitoring process, the main CPU 71 operates the RB gaming state based on the BB operating flag and the RB operating flag. The BB operating flag is information for identifying whether or not to operate the RB gaming state. The RB operating flag is information for identifying whether the gaming state is the RB gaming state.

Specifically, when the BB operation flag is ON, the main CPU 71 updates the RB operation flag to ON when the RB game state ends, and the RB game state starts again. I do. That is, after the symbol combination corresponding to BB is displayed along the activated line, the RB game state is maintained until the BB operating flag is updated to OFF. Further, the main CPU 71 stores the initial value of the number of possible games (for example, 12 times) and the initial value of the number of possible winnings (for example, 8 times) in the RAM 33.

In S4, the main CPU 71 executes medal acceptance/start check processing, and subsequently executes processing of S5. Here, the main CPU 71 updates the information of the inserted number based on the input (signal) from the start switch 17S, the first medal sensor 120, or the BET switches 13 to 15, and turns on the BET lamps 7a to 7c. The process of turning off the light, the process of transmitting the bet command and the demo command to the sub control circuit 72, and the like are performed. The sub-control circuit 72 that has received the bet command controls the liquid crystal display unit 2b to display an image as an effect performed at the time of the insertion operation. In addition, the sub-control circuit 72 that has received the demo command performs control to display a so-called demo image on the liquid crystal display unit 2b.

In S5, the main CPU 71 extracts a random number value, stores it in the random number value storage area, and then performs the process of S6. The random number value extracted in this process is used in the internal lottery process (S7 described later).

In S6, the main CPU 71 carries out a game state monitoring process, and subsequently carries out a process of S7.
In this game state monitoring process, the main CPU 71 determines (shifts) the game state based on the RB operating flag. Specifically, the main CPU 71 determines whether or not the RB operating flag is on, and if the RB operating flag is on, an identifier (information) indicating the RB gaming state is predetermined in the RAM 33. Store in the storage area. On the other hand, if the RB operation flag is off, the identifier (information) indicating the general gaming state is stored in a predetermined storage area of the RAM 33.

In S7, the main CPU 71 carries out the above-mentioned internal lottery processing, and subsequently carries out the processing of S8. In this internal lottery process, the main CPU 71 determines the number of lottery times according to the gaming state. Specifically, when the gaming state is the RB gaming state, the main CPU 71 determines "3" as the number of times of lottery.

On the other hand, when the gaming state is the general gaming state, the main CPU 71 basically determines "6" as the number of times of lottery. However, when the combination of symbols corresponding to BB is allowed to be displayed along the activated line over one or more games, the main CPU 71 determines “4” as the lottery number. Therefore, when the combination of the symbols corresponding to BB is allowed to be displayed along the activated line over one or more games, since "5" or "6" is not determined as the lottery number, BB1, Alternatively, BB2 is never decided as the internal lottery.

In S8, the main CPU 71 carries out a process of transmitting a start command to the sub control circuit 72, and then carries out the process of S9. The start command includes information such as a game state and an internal lottery combination, and is transmitted to the sub control circuit 72. In S9, the main CPU 71 requests the start of rotation of all reels, and then executes the process of S10.

In S10, the main CPU 71 executes a reel stop control process, and then executes a process of S11. In this reel stop control process, the main CPU 71 controls the rotation of the reels 3L, 3C, 3R based on the internal lottery combination, the timing of the stop operation by the player, and the like.

In S11, the main CPU 71 determines the display combination and the number of payouts based on the symbol combination table, and subsequently performs the process of S12. Specifically, the main CPU 71 determines the display combination and the payout number based on the symbol combination table displayed in the display windows 21L, 21C, 21R and the symbol combination table.

In S12, the main CPU 71 performs a process of transmitting the display combination command to the sub control circuit 72, and then performs the process of S13. This display combination command includes the information of the display combination determined in S11. Upon receiving the display combination command, the sub-control circuit 72 controls the liquid crystal display unit 2b to display an image as an effect performed after all reels 3L, 3C, 3R are stopped.

In S13, the main CPU 71 conducts a process of checking the number of passed medals passing through the medal ejection guide 130, and subsequently carries out the process of S14. In the medal passing number checking process, it is determined whether the medals passing through the medal ejection guide 130 are passing alone or in an overlapping manner based on the detection value of the second medal sensor 132, and the number of passing medals is accurately determined. While counting and comparing with the count value of the first medal sensor 120, abnormality such as fraudulent activity or clogging is determined, and an alarm is issued if necessary.

In S14, the main CPU 71 carries out a medal payout process, and subsequently carries out a process of S15.

In S15, the main CPU 71 updates the bonus end number counter for counting the bonus end number information based on the payout number, and then performs the process of S16. Here, the main CPU 71 determines whether either the RB operation flag or the BB operation flag is on. When this determination is "YES", the process of S17 is subsequently performed, and when this determination is "NO", the process of S18 is subsequently performed.

In S17, the main CPU 71 conducts bonus end check processing, and subsequently performs processing in S18.
In the bonus end check process of S17, the main CPU 71 ends the bonus game when the condition for ending the bonus game is satisfied.

Specifically, when the value of the bonus end number counter is "0", the main CPU 71 executes the RB end process and the BB end process, and the information on the number of possible wins is "0" or the number of possible games. When the information is "0", the RB end processing is performed. In the RB end process, the main CPU 71 clears the RB operation flag, information on the number of possible winnings, information on the number of possible games, and the like. In the BB end process, the main CPU 71 clears the BB in-operation flag and the bonus end number counter.

In S18, the main CPU 71 conducts bonus operation check processing, and subsequently returns to S2. In the bonus operation check process of S18, the main CPU 71 starts the bonus game when the start condition of the bonus game is satisfied. In the embodiment, the main CPU 71 BBs on the condition that a combination of symbols corresponding to BBs (“red 7-red 7-red 7” or “BAR-BAR-BAR”) is displayed along the activated line. Perform processing during operation.

In this BB operation process, the main CPU 71 updates the BB operation flag corresponding to BB1 or BB2 to ON, and sets a predetermined value (for example, "350") defined in advance as the initial value of the bonus end number counter. ..

[Medal reception/start check processing]
The medal acceptance/start check processing S4 of FIG. 11 executed by the main CPU 71 will be described with reference to FIG.

First, in S20, the main CPU 71 determines whether or not there is an automatic medal insertion request. If “YES”, the process proceeds to S21, and if “NO”, the process proceeds to S28.

If there is an automatic loading request in S20, the main CPU 71 carries out an automatic loading process, and moves the process to S28.

On the other hand, if there is no automatic insertion request, the main CPU 71 executes medal acceptance permission processing in S22, and proceeds to S23.

Next, the main CPU performs a process of setting the maximum value of the inserted number according to the game state in S23, and proceeds to S24.

Next, the main CPU 71 determines in S24 whether or not the medal acceptance is permitted. If “YES”, the process proceeds to S25, and if “NO”, the process proceeds to S28.

Next, the main CPU 71 conducts a medal insertion check process in S25. In the medal insertion check process, the inserted medals are detected by the first medal sensor 120, and the detection result is output to a first medal counter (hereinafter, referred to as “first medal counter”) provided in the RAM 33, and is used as the number of medals. Store. Next, a medal insertion command transmission process is performed in S26, and the process proceeds to S27.

Next, in S27, the main CPU 71 determines whether or not the inserted number is the game startable number. If “YES”, the process proceeds to S28, and if “NO”, the process proceeds to S29.

Next, the main CPU 71 conducts settlement switch check processing in S28, and proceeds to S29.

Next, in S29, the main CPU 71 determines whether or not the start switch is ON, and if “YES”, the process proceeds to S30 to perform medal acceptance prohibition processing, and ends the medal acceptance/start check processing.

On the other hand, in the case of “NO”, the process returns to S24.

[Settlement switch check processing]
The settlement switch check process S28 in the medal acceptance/start check process of FIG. 12 executed by the main CPU 71 will be described with reference to FIG.

First, the main CPU 71 determines in S40 whether or not the settlement (C/P) switch 16S is turned on.

If "YES", the process proceeds to S41, and if "NO", the settlement switch check process ends.

Next, the CPU 71 performs a medal payout process in S41, and proceeds to S42.

Next, the CPU 71 performs a medal passage number check process in S42, and thereafter ends the settlement switch check process.

[Periodic interrupt processing by control of main control circuit (main CPU)]
The regular interrupt processing S50 under the control of the main CPU 71 will be described with reference to FIG. In the present embodiment, this interrupt process is performed every 1.1172 ms.

First, the main CPU 71 saves registers (S51). Next, the main CPU 71 conducts input port check processing (S52). In this process, signals input from various switches such as the stop switch 18LS are checked.

Next, the main CPU 71 carries out a timer updating process (S53), and then the main CPU 71 carries out a communication data transmitting process (S54). In this processing, various command data stored in the communication data storage processing is transmitted to the sub control circuit 72.

Next, the main CPU 71 conducts reel control processing (S55). In this process, when the rotation start of all reels is requested, the drive of the stepping motors 49L, 49C, 49R is controlled so as to start the rotation of each reel 3L, 3C, 3R and then rotate at a constant speed. To be done. Further, when the number of sliding pieces is determined, the symbol counter of the corresponding reel is updated by the number of sliding pieces. Then, after waiting for the updated symbol counter to match the value according to the planned stop position (the symbol at the planned stop position reaches the middle stage of the display window), the rotation of the corresponding reel is decelerated and stopped. The drive of the stepping motor is controlled.

Next, the main CPU 71 conducts a lamp/7-segment drive process (S56). In this process, the drive control of the 7-segment display 6 is performed to display the number of payouts, the number of credits, and the like.

Next, the main CPU 71 conducts a medal passage check process based on the output value of the second medal sensor 132 provided on the medal ejection guide 130 (S57). The details will be described later.

After the end of S57, the main CPU 71 executes a register restoration process (S58). When this process ends, the main CPU 71 ends the interrupt process.

[Medal passage check processing]
The medal passage check process executed in S57 of the interrupt process under the control of the main control circuit (main CPU) in FIG. 14 will be described with reference to FIG.

First, in S71, the main CPU 71 determines whether or not the second medal sensor 132, which is provided in the medal guide passage 102 and detects the medals passing through the medal ejection guide 130, is ON, and is “YES” (that is, ON state). If so, the process proceeds to S72, and if "NO" (that is, the off state), the process proceeds to S76.

If "YES" in S71, the main CPU 71 subtracts 1 from the value of the medal passage timer (hereinafter referred to as "medal passage timer") provided in the RAM 33 in S72 (S72).
At this time, if the previous medal passage check process is “NO”, “1” is added to the second medal counter (hereinafter, referred to as “second medal counter”) provided in the RAM 33. That is, when the second medal sensor 132 changes from the off state to the on state (also referred to as an on-edge detection), it is determined that one medal has passed, and the value of the second medal counter (“0” in this example). Is incremented by 1 and the value of the second medal counter is changed from "0" to "1".

Next, the main CPU 71 determines in S73 whether or not the value of the medal passage timer is zero (0). If it is zero, the process proceeds to S74, and if it is not zero, the process returns to S57.

Next, the main CPU 71 adds 1 to the value of the second medal counter in S74, and proceeds to S75. That is, in this example, the value of the second medal counter changes from "1" to "2".

Next, in S75, the main CPU sets the medal passage timer to the initial value (“38” in the present embodiment), and returns to S57.

The initial value "38" of the medal passage timer means the number of interruption processes, and if the value of the medal passage timer becomes "0" in S73, the interruption process is performed 38 times, and during that period, That is, it means that the second medal sensor 132 is in the ON state for 42.4536 ms (38 times×1.1172 ms), that is, continues to detect medals.

Next, the main CPU 71 sets the medal passage timer to "0" in S76, and returns to S57.

As described above, in the medal passage check process, the number of medals can be accurately counted even when two or more medals are overlapped and passed.

However, as described above, when the degree of overlap is high (FIG. 8(b), FIG. 9(b)), for example, 3 or 4 medals may be erroneously counted as 2 or 3. Since such an incorrect counting is considered to occur less frequently, it is processed as a counting error.

As a modified example, in the medal passage check process immediately after the medal passage timer is set to the initial value (38) in S75, when the second medal sensor 132 is turned on in S71 (in the case of “YES”), You may make it add "1" to the value of a 2 medal counter. For example, if the value of the second medal counter is “2” at the time when the number of interrupts reaches 38 with the second medal sensor 132 remaining in the ON state (approx. 42.5 msec), the medal passage immediately after that is performed. If the second medal sensor 132 continues to be turned on in the checking process, the value of the second medal counter is incremented by "1" to be "3", and if the on state continues 38 times, the second medal at that point The value of the second medal counter is set to "1" in order to correct the value of the second medal counter at the time when it is turned off in less than 30 times by adding "1" to the value of the counter to be "4". The subtraction may be performed.

In addition, when the ON duration is a certain time or longer (for example, when the ON duration is 100 msec or more), it is possible to treat the medal as being clogged.

[Medal number check process]
The medal passing number check processing executed by the main CPU 71 in S13 of FIG. 11 and S42 of FIG. 13 will be described with reference to FIG.

First, the main CPU 71 determines in S80 whether or not the second medal sensor 132 is on. If “NO”, the process proceeds to S81, and if “YES”, the process proceeds to S88.

In S81, the main CPU 71 determines whether or not the value of the first medal counter is "zero". If "NO", the process proceeds to S82, and if "YES", the process proceeds to S89. Here, the value of the first medal counter is the number of medals detected by the first medal sensor 120.

In S82, the main CPU 71 sets the allowable difference number to "0", and proceeds to S83.

Next, the main CPU 71 determines in S83 whether or not the value of the first medal counter is within the range of 1 to 4. If "NO", the process proceeds to S83, the allowable difference number is set to "1" in S83, and the process proceeds to S87. On the other hand, if “YES”, the process proceeds to S87.

Next, the main CPU 71 determines in S85 whether the value of the first medal counter is within the range of 5 to 14. If "NO", the process proceeds to S86, the allowable difference number is set to "2" in S86, and the process proceeds to S87. On the other hand, if “YES”, the process proceeds to S87.

Next, the main CPU 71 subtracts the value of the second medal counter from the value of the first medal counter in S87, and determines whether the subtracted value is equal to or less than the allowable difference number. Here, the value of the second medal counter is the number of medals counted by the second medal sensor.

If the determination result is "NO", the process proceeds to S88, and if "YES", the process returns to S81.

Next, the main CPU 71 determines in S88 that an abnormality has occurred, performs error processing, and proceeds to S89. In the error processing, a 2-digit error code (for example, “CC”) is displayed on the 7-segment LED of the payout amount display unit 10. In the error processing, the progress of the game is suspended until the generated error factor is released, and after the error factor is released, the progress of the game is restarted from the point of interruption.

In S89, the main CPU 71 sets the value of the first medal counter and the value of the second medal counter to "0", and proceeds to S90.

In S90, the main CPU 71 sets the medal passage switch timer to "0" and finishes the medal passage number check process.

In the present medal number check process, in order to reduce the control load, the number of medals detected by the first medal sensor 120 and counted by the first medal counter is divided into three ranges, that is, 1 to 4 Although it is divided into 3 ranges of 5 to 14 sheets and 15 or more sheets and the allowable difference number (that is, 0 sheet, 1 sheet, 2 sheets) is defined for each, the number is not limited to this, and the number of divided ranges and the allowable range are set. The difference number can be changed appropriately. Further, the allowable difference number may be set to a certain ratio of the numbers counted by the first medal counter detected by the first medal sensor 120, for example, about 20% or less, without dividing the number of medals into a plurality of ranges.

Although the embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, combinations, replacements, and changes can be made without departing from the spirit of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the scope equivalent thereto. Further, in the above-described embodiments and modified examples, a pachi-slot machine was described as an example of a gaming machine, but the present invention is not limited to this, and the present invention is also applicable to a gaming machine called a “pachinko machine”. For example, the same effect can be obtained by providing a second sensor at the discharge port of the game ball of the upper plate by the ball payout of the game ball payout device of the pachinko machine.
