It arrange | positions so that it may oppose front and back on both sides of an upper side, for example, it is detachably fixed to the downstream cover plate 44 side via the support bracket 33a.

  The detection means for determination 34 detects a medal based on a mechanical operation received from a medal flowing down the guide passage 31, and is arranged corresponding to the non-permitted return position B on the medal drop hole 55, for example. As shown in FIGS. 5, 6, 8, 9, and the like, the operating piece 63 is guided to the non-operating state in which the operating piece 63 protrudes toward the guide passage 31, and pushed by a medal flowing down in the guide passage 31. An operating member 64 that can be changed to an operating state retracted toward the outside of the passage 31 and a determination switch 65 that detects that the operating member 64 is in the operating state are provided.

  The operating member 64 is disposed, for example, on the front surface side of the base plate 41, and is provided with a rotating shaft portion 66 supported so as to be rotatable around a substantially vertical axis, and projecting from the rotating shaft portion toward the downstream side of the guide passage 31. The rotating arm portion 67, the operating piece 63 projecting backward from the distal end side of the rotating arm portion 67, and extending from the distal end side of the rotating arm portion 67 in a predetermined direction, for example, downstream of the guide passage 31. The provided detection piece 68 is integrally provided, for example.

  The actuating member 64 includes a non-actuated state (FIG. 9A) in which the actuating piece 63 protrudes to the guide passage 31 side through the through hole 69 on the base plate 41 side, and the actuating piece 63 is outside the guide passage 31. That is, it can swing between the operation state retracted toward the front side (FIG. 9B) and is elastically biased to the non-operation state side by the spring member 70. It should be noted that the distal end side edge portion of the operating piece 63 is formed in an inclined shape in which the protruding amount toward the guide passage 31 gradually increases from the upstream side to the downstream side of the guide passage 31 when in the inoperative state. .

  The determination switch 65 is constituted by, for example, a transmission type photosensor, and is disposed at a position where the detection piece 68 is detected when the operation member 64 is in an operation state.

  The operating member 64, the determination switch 65, and the like are detachably mounted on the front side of the base plate 41 via one mounting frame 71.

  The operation of the medal sorting means 26 having the above configuration will be briefly described. The medals inserted into the medal insertion slot 17 enter the guide passage 31 from the passage entrance 31a, and flow down while rolling on the medal guide rail 45 with the front and rear guided by the base plate 41 and the upstream cover plate 43. When the medal reaches the medal sorting position A, if the medal is an appropriate medal, the upper and lower ends are held from the front side by the upper guide 48 and the lower guide 47 and the opening window 46 is moved to the downstream side. It passes through (Fig. 7 (a)).

  On the other hand, in the case of an improper medal having a diameter smaller than that of the appropriate medal, when reaching the medal sorting position A, the upper end side is not supported by the upper guide 48 and only the lower end side is supported by the lower guide 47 from the front side. Therefore, it falls on the guide plate part 42b on the front side through the opening window 46 from the upper end side, is guided by the inclination of the guide plate part 42b, and returns to the lower side through the notch part 43a on the upstream cover plate 43 side. It falls to the passage 27 side and is returned to the medal tray 25 side (FIG. 7C).

  As described above, the improper medal removal means 32 for removing the improper medal from the guide passage 31 at the medal sorting position A is the opening window 46, the upper guide 48, the lower guide 47, the removal guide plate 42, and the upstream cover plate. 43 notches 43a and the like.

  For example, when an improper medal thicker than the appropriate medal is inserted into the medal insertion slot 17, it is sandwiched between the base plate 41 and the upstream cover plate 43 when entering the guide passage 31 from the passage entrance 31a. Flow is prevented. In this state, when the player depresses the return button 18, the removal guide plate 42 swings backward to the forced guide state via the interlocking member 51, and the upstream cover plate 43 swings backward in conjunction therewith. To be separated from the base plate 41 (FIG. 7B). As a result, the improper medal sandwiched between the base plate 41 and the upstream cover plate 43 flows down along the medal guide rail 45 and is guided by the guide plate portion 42b protruding into the opening window 46 at the medal sorting position A. It is guided to the front side, falls to the lower return passage 27 side, and is returned to the medal tray 25 side.

  For example, if the number of credits has reached the upper limit value (50), the blocker solenoid 58 is held in the ON state, and the open / close plate 57 has the open / close plate portion 57b. Is closed, and the medal guidance state in which the medal is guided downstream (FIG. 8A). Accordingly, an appropriate medal that has passed through the medal sorting position A without being removed by the improper medal removal means 32 is not permitted along the guide passage 31 without falling from the medal drop hole 55 except during a medal acceptance period. Pass the return position B.

  When passing through the non-permitted return position B, the medal flows down while pushing the operating piece 63 protruding toward the guide passage 31 to the outside of the guide passage 31 (FIGS. 9A to 9B). During a predetermined time during which the operating piece 63 is pressed by the medal, the operating member 64 swings to change from the non-operating state to the operating state, and the determination switch 65 detects the detecting piece 68 and turns ON.

  During the medal unacceptable period, the blocker solenoid 58 is in the OFF state and the medal drop hole 55 is opened (FIG. 8B), so that the medal selection position is not removed by the inappropriate medal removal means 32. The appropriate medal that has passed through A falls to the return passage 27 side from the medal drop hole 55 and is returned to the medal tray 25 side. In this embodiment, the medal also pushes the operating piece 63 at this time, The switch 65 is turned on for a predetermined time.

  The appropriate medals that have passed through the non-permitted return position B along the guide passage 31 are sequentially detected by the first and second appropriate medal switches 61 and 62, and then discharged from the passage outlet 31b. Guided to the side.

  FIG. 11 is a block diagram of the control system of the slot machine. This control system is mainly composed of a game control means 81 that performs control related to the gaming state, and an effect control means 82 that performs control related to effects. The game control means 81 and the effect control means 82 are provided on separate boards. For example, the game control means 81 includes the symbol display reels 5a to 5c, the start lever 22, the stop buttons 23a to 23c, the insertion button 19, 20, determination detection means 34, appropriate medal count detection means 33, blocker solenoid 58, credit display means 14, earned medal display means 15, credit settlement button 21, medal payout means 11 and the like are connected to effect control means 82. Are connected to a lamp 83, a speaker 84, and the like. The production control unit 82 performs control based on a control command transmitted from the game control unit 81.

  The game control means 81 is constituted by a CPU, a ROM, a RAM, and the like, and a game control processing program is stored in advance in the ROM. By executing this game control processing program on the CPU for each game, FIG. The game control process shown in FIG.

  In the game control process, as shown in FIG. 12, a RAM clear process (S1) is first performed, and then a medal insertion process (S2) which is a game start condition is performed. When it is confirmed in the medal insertion process (S2) that a predetermined number (three in this case) of medals has been inserted, a game is possible.

  After that, when the player operates the start lever 22, a random number extraction process (S3) for extracting a predetermined lottery random number is performed, and the symbols are combined in a jackpot mode set in advance based on the extracted random number value. A symbol lottery process (S4) for determining whether or not to permit the stop is performed, and at the same time, the three symbol display reels 5a to 5c start to rotate simultaneously by the symbol variation start process (S5).

  When the player operates the stop buttons 23a to 23c in an arbitrary order after the rotation of the symbol display reels 5a to 5c is stabilized, the symbol change reels 5a to 5c are rotated by a predetermined number of frames by the symbol variation stop process (S6). It is stopped with a sliding motion (for example, 0 to 4 frames). Thereby, when it is permitted to stop in a predetermined mode such as a big hit mode in the symbol lottery process (S4), the big hit mode or the like or the off mode depending on the operation timing of the stop buttons 23a to 23c of the player If it is not permitted to stop in a predetermined mode such as a big hit mode, the player always stops in a disengaged mode regardless of the operation timing of the stop buttons 23a to 23c of the player.

  When all the symbol display reels 5a to 5c are stopped, the combination of symbols that are stopped and displayed on the predetermined winning line by the winning determination process (S7) is a big win mode, a small hit mode, a small role mode, a replay mode, It is determined which of the detachment modes and the like. Then, when the determination result is any one of the big hit mode determination, the small hit mode determination, and the small role mode determination, a predetermined number of medals are added to the credit number by the medal payout process (S8). Alternatively, the tokens are paid out to the medal tray 25 by driving the medal payout means 11.

  The acquired medal number is displayed on the acquired medal display means 15, and when the credit number is added, the value of the credit number displayed on the credit display means 14 is updated.

  After that, for example, if it is determined by the winning determination process (S7) that the replay mode, the big hit mode, or the small win mode is (S9, S11 or S13: Yes), the replay start processing (S10), BB (big bonus) ) Start processing (S12) or RB (regular bonus) start processing (S14) is performed.

  Further, if it is either BB or RB (S15 or S17: Yes), a predetermined BB process (S16) or RB process (S18) is performed, and the game control process is completed.

  In addition, the game control means 81 executes the game control process as described above for each game, and during the game control process, the periodic interrupt process shown in FIG. 13 is performed at predetermined time intervals (for example, every 1.490 ms). Is to be executed.

  Hereinafter, a more specific processing procedure for the periodic interruption process and the medal insertion process (S2) in the game control process will be described.

  In the periodic interrupt process (FIG. 13), it is determined how the ON / OFF state of the determination detecting unit 34 has changed since the previous periodic interrupt process (S21, S25, S29), and according to the determination result. Predetermined processing is performed.

  That is, for example, when the state of the detection means for determination 34 changes from OFF to ON (S21: Yes), if it is in the game (S22: Yes), the error flag is set to ON (S23), and the game If it is not medium (S22: No), an initial value is set in the detection time timer for determination (S24), and the periodic interrupt process ends.

  The initial value set in the detection time timer for determination is set to a value corresponding to the allowable upper limit value of the ON state continuation time of the determination detection means 34 (the time from the rise to the fall of the medal detection signal). . This allowable upper limit value may be set to a time slightly longer than the duration when the detection means for determination 34 is turned on by inserting a proper medal. In this embodiment, it is assumed that the allowable upper limit value of the ON state duration of the detection means for determination 34 is about 200 ms, and 134 (≈200 / 1.490) is set as the initial value in the detection time timer for determination.

  When the state of the detection means for determination 34 has not changed from the previous ON state (S25: Yes), the value of the detection time timer for determination is subtracted (S26), and the timer value after the subtraction is 0. In other words, if the duration of the ON state of the detection means for determination 34 (hereinafter referred to as the detection time for determination) reaches the allowable upper limit (S27: Yes), the error flag is set to ON (S28). Periodic interrupt processing ends.

  When the state of the detection means for determination 34 changes from ON to OFF (S29: Yes), a predetermined number X (here, 1) is added to the medal count number MCNT (S30), and the medal count number after the addition If the value of MCNT is not within the proper range (second proper range) (S31: Yes), the error flag is set to ON (S32), and the periodic interrupt process ends. The appropriate range of the value of the medal count number MCNT after the addition in S30 is the maximum value of the number of subsequent medals already detected by the determination detection means 34 at the time of detection of the medal by the appropriate medal count detection means 33. Assuming that the number is 1 (here, 1) (see FIG. 6), 0 ≦ α, and MCNT ≦ X × (Y + 1) + α. In the present embodiment, α is set to 3, and the appropriate range of the medal count number MCNT is set to MCNT ≦ 5. That is, when the value of the medal count number MCNT exceeds 5 in S31, the error flag is set to ON.

  Next, a specific procedure of the medal insertion process (FIG. 14) will be described. In the medal insertion process, it is first determined whether or not the error flag is set to ON (S41). If the error flag is set to ON (S41: Yes), a predetermined error process is executed. (S42). That is, when the error flag is turned ON in S23, S28 or S32 in the immediately preceding periodic interrupt process (FIG. 13), the error process is executed here.

  In this error processing, for example, the game is stopped, the occurrence of an error is notified by voice, a lamp, etc., and the blocker solenoid 58 is switched OFF, and all medals inserted into the medal slot 17 thereafter are dropped. It falls into the return passage 27 from the hole 55 and is returned to the medal tray 25.

  Subsequently, it is determined whether or not the game is a replay (S43). If it is a replay, a medal insertion process at the time of the replay is performed (S44). That is, the value of the number of inserted medals is set to, for example, three without subtracting the number of credits and without accepting the insertion of medals from the medal insertion slot 17.

  On the other hand, when it is determined in S43 that the game is not a replay, a medal insertion detection process is performed (S45). This medal insertion detection process (S45) is performed in the procedure as shown in FIG. That is, first, it is determined whether or not the value of the number of inserted medals is already three (S61). If the number of inserted medals is three (S61: Yes), the number of credits is the upper limit. On condition that the medal acceptance period is exceeded (S62: Yes), the blocker solenoid 58 is switched OFF (S63), and the medal insertion detection process ends here.

  When the blocker solenoid 58 is switched off, the open / close plate 57 of the medal drop hole opening / closing means 56 changes from the medal guide state to the medal drop state (see FIG. 8). Is a proper medal, it falls into the return passage 27 from the medal dropping hole 55 and is returned to the medal tray 25.

  When the number of inserted medals is less than 3 (S61: No), or when the number of inserted medals has reached 3 and the number of credits has not reached the upper limit (50) (S61: Yes → S62: No) ), Determination processing of a detection signal of the appropriate medal count detection means 33 is performed (S64).

  The determination processing of the detection signal of the appropriate medal count detection means 33 is performed based on the detection signals from the first and second appropriate medal switches 61 and 62 constituting the appropriate medal count detection means 33. This is performed by determining whether or not a predetermined error detection condition is satisfied. This error detection condition is set as shown in FIG. 16, for example.

  That is, when both the first appropriate medal switch 61 and the second appropriate medal switch 62 are OFF (section a), the first appropriate medal switch 61 and the second appropriate medal switch 62 are simultaneously turned ON, or An error is determined when only the second appropriate medal switch 62 is turned on. When only the first appropriate medal switch 61 is ON (section b), the first appropriate medal switch 61 is turned OFF or only the first appropriate medal switch 61 is ON for a predetermined time (for example, 100 ms) or longer. If it continues, it is determined as an error.

  When both the first appropriate medal switch 61 and the second appropriate medal switch 62 are ON (section c), the second appropriate medal switch 62 is turned OFF or the first appropriate medal switch 61 and the second appropriate medal An error is determined when both the switches 62 are ON for a predetermined time (for example, 100 ms) or longer. When only the second appropriate medal switch 62 is ON (section d), the first appropriate medal switch 61 is ON or only the second appropriate medal switch 62 is ON for a predetermined time (for example, 100 ms) or longer. If it continues, it is determined as an error.

  If the detection signal from the appropriate medal count detection means 33 changes from the section a to the section a through the sections b, c, and d without satisfying the error detection condition, the correct medal is normal. It is determined that it was thrown in.

  If it is not determined in S64 that the proper medal has been normally inserted, that is, if the detection signal of the proper medal count detection means 33 satisfies the error detection condition shown in FIG. 16, or the proper medal count detection means If the detection signal from 33 does not satisfy the error detection condition shown in FIG. 16 but has not yet reached the section a again from the section a via the sections b, c, d (S65: No), there is a medal. The input detection process ends.

  If it is determined in S64 that a proper medal has been inserted normally (S65: Yes), a predetermined number X (1 here) is subtracted from the value of the medal count number MCNT (S66). If the value of the medal count MCNT after the subtraction is within the proper range (first proper range), the medal insertion flag is set to ON (S67: Yes → S69), and if it is not within the proper range, an error occurs. The flag is set to ON (S67: No → S68), and the medal insertion detection process ends.

  The appropriate range of the value of the medal count number MCNT after subtraction in S66 is the maximum value of the number of subsequent medals already detected by the determination detection means 34 at the time of detection of the medal by the appropriate medal count detection means 33. If the number is 1 (here, 1) (see FIG. 6), 0 ≦ MCNT ≦ X × Y, that is, 0 ≦ MCNT ≦ 1. Therefore, if the value of the medal count number MCNT is neither 0 nor 1 in S67, the error flag is set to ON.

  When the above medal insertion detection process (S45) is completed, the detection process of the insertion buttons 19 and 20 is performed (S46). That is, on the condition that the insertion buttons 19 and 20 are operated, the number of credits is subtracted and the number of inserted medals is added.

  When the process of S44 or S46 ends, it is determined whether or not the medal insertion flag is ON (S47). When it is determined in S47 that the medal insertion flag is ON, that is, when the medal detection is normally performed by the appropriate medal count detection means 33, the number of medal insertions at that time is already the maximum value ( For example, if it has reached 3), 1 is added to the number of credits (S48: Yes → S50), and if the number of inserted medals has not yet reached the maximum value (for example, 3), 1 is added to the number of inserted medals. (S48: No → S49).

  If there is a medal insertion (S51: Yes) and the start lever 22 is operated (S52: Yes), the medal insertion process ends here. If no medal has been inserted (S51: No), or if a medal has been inserted but the start lever 22 has not yet been operated (S51: Yes → S52: No), the processing from S41 onward is repeated. Here, in the case of a three-sheet dedicated machine, in S51, it may be determined whether or not the value of the number of inserted medals has reached the maximum value of three.

  If the error flag is set to ON in S68 immediately before, the medal insertion flag is not set to ON, so that 1 is not added to the medal insertion number in S48, and in S42 in the next repetitive processing. Error handling is performed.

  FIGS. 17A and 17B are examples of detection histories of the determination detection means 34 and the appropriate medal count detection means 33 when a proper medal is normally inserted before the start of the game. First, FIG. 17A shows an example in which only one appropriate medal is inserted. In this case, since the rising point (T11) of the detection means 34 for determination from OFF to ON is before the start of the game, the error flag is not set to ON in S23. Further, since the detection time for determination from the time when the detection means for determination 34 is turned on until it is turned off (T11 → T12) is 200 ms or less, the error flag is not set to ON in S28. In addition, since the value of the medal count number MCNT after addition of 1 at the time point (T12) when the detection means for determination 34 falls from ON to OFF is 1, and the condition of MCNT> 5 is not satisfied, an error is detected in S32. The flag is never set ON.

  Furthermore, since the value of the medal count number MCNT after subtraction of 1 at the medal detection time (T13) by the appropriate medal count detection means 33 is 0 and the condition 0 ≦ MCNT ≦ 1 is satisfied, an error flag is set in S68. Is never set to ON.

  Accordingly, in the case of FIG. 17A, the error processing is not performed in S42 in the medal insertion process, and it is assumed that the medal insertion is normal, and at the medal detection time point (T13) by the appropriate medal count detection means 33. 1 is added to the number of medals inserted or the number of credits.

  FIG. 17B shows an example in which two appropriate medals are continuously inserted. In this case, the second medal passes through the determination detection means 34 (T11 ′ →) before the time point (T24) when the first medal is detected by the appropriate medal count detection means 33. Therefore, the value of the medal count number MCNT after 1 subtraction at the first medal detection time (T13) by the appropriate medal count detection means 33 is 1, but this also satisfies the condition of 0 ≦ MCNT ≦ 1. Therefore, the error flag is not set to ON in S68.

  In other S23, S28, and S32, the error flag is not set to ON as in the case of FIG. Accordingly, also in the case of FIG. 17B, the error processing is not performed in S42 in the medal insertion process, and it is assumed that the medal insertion is normal, and at the medal detection time (T13) by the appropriate medal count detection means 33. 1 is added to the number of medals inserted or the number of credits.

  18 to 21 are examples of detection histories of the determination detection means 34 and the appropriate medal count detection means 33 when an illegal operation is performed on the medal insertion process. In the case of FIG. 18, since the detection time for determination exceeds 200 ms from when the detection means for determination 34 is turned on until it is turned off (T21 → T22), when the detection time for determination exceeds 200 ms. In S28, the error flag is set to ON, and error processing is performed in S42 in the medal insertion process.

  The situation as shown in FIG. 18 is a situation that is not possible when a medal is inserted normally, except in a special case where the medal is jammed in the state detected by the detection means 34 for determination. For this reason, it is assumed that the fraud has occurred and error processing is performed.

  In the case of FIG. 19, before the medal detection by the appropriate medal count detection means 33, ON / OFF by the determination detection means 34 is repeated six times, and the medal at the sixth falling time from ON to OFF (T31). Since the count number MCNT is 6 and MCNT> 5 is satisfied, the error flag is set to ON in S32, and error processing is performed in S42 in the medal insertion process.

  The situation as shown in FIG. 19 is not possible when a medal is inserted normally except for a special case such as an abnormality in the detection means 34 for determination. Error handling.

  In the case of FIG. 20, when the ON / OFF by the detection means for determination 34 is repeated three times and the medal is detected by the detection means 33 for proper medal count thereafter (T41), the medal count number after 1 subtraction. Since the value of MCNT is 2 and the condition of 0 ≦ MCNT ≦ 1 is not satisfied, the error flag is set to ON in S68, and error processing is performed in S42 in the medal insertion process.

  The situation as shown in FIG. 20 is a situation that is not possible when a medal is inserted normally except for a special case such as an abnormality of the detection means for determination 34. Error handling.

  In the case of FIG. 21, the medal is detected by the appropriate medal count detection means 33 even though the determination detection means 34 is not turned ON / OFF. The value of the medal count number MCNT after 1 subtraction at T51) is −1 and does not satisfy the condition of 0 ≦ MCNT ≦ 1, so the error flag is set to ON in S68, and error processing is performed in S42 in the medal insertion process. Done.

  The situation as shown in FIG. 21 is a situation that is impossible when a medal is inserted normally except for a special case such as an abnormality in the determination detection unit 34, and therefore, it is estimated that there was an injustice. Error handling.

  As described above, in the slot machine of the present embodiment, the determination for detecting medals based on the mechanical operation provided from the medals provided upstream of the appropriate medal count detection means 33 and flowing down the guide passage 31. The detection means 34 is provided and is configured to determine whether or not the medal insertion is appropriate based on the detection signal from the determination detection means 34 and the detection signal from the appropriate medal count detection means 33. In order to carry out fraud, it is necessary to cause the detection means 34 for determination as a mechanical switch to malfunction at the same time in addition to the detection means 33 for proper medal count. In addition to the fact that fraudulent acts using conventional slot insertion-type fraudulent devices that increase credits are impossible, new fraudulent devices There is an advantage that can prevent fraud effectively by.

  The predetermined value X is added to the determination medal count value MCNT based on the medal detection by the determination detection means 34, and the predetermined value X is calculated from the determination medal count value MCNT based on the medal detection by the appropriate medal count detection means 33. It is configured to subtract, and it is determined that the medal insertion is inappropriate on condition that the value of the determination medal count value MCNT after the medal detection by the appropriate medal count detection means 33 is not within the first appropriate range. Therefore, the determination is made when the appropriate medal count detection means 33 is in the detection state without detection by the determination detection means 34 or before the proper medal count detection means 33 is in the detection state. The medal count can be invalidated when the detection means 34 is in a detection state a number of times that cannot be in a normal state. Order can be effectively eliminated.

  In addition, since the determination medal count value MCNT is not within the second appropriate range after the detection by the determination detection unit 34, it is determined that the medal insertion is inappropriate. If the detection means 34 for determination is continuously detected for a number of times that cannot be in a normal state, it can be determined that the determination is inappropriate at that time, and fraud can be effectively eliminated.

  Further, since the medal insertion state is determined to be inappropriate on condition that the duration of the medal detection state by the determination detection unit 34 exceeds the upper limit value, the detection by the determination detection unit 34 is detected. It is possible to determine that the state is inappropriate when the state continues for a long time which cannot be a normal state, and it is possible to effectively eliminate fraud.

  Further, since it is determined that the insertion of the medal is inappropriate under the condition that the detection means 34 for determination is detected during the game, the reliability of fraud elimination is further improved.

  Further, since the determination detection means 34 is arranged so as to detect medals downstream from the medal selection position A, the determination detection means only when it is not excluded as an inappropriate medal at the medal selection position A. It is possible to determine fraud based on 34, etc., and to prevent the control process from becoming more complicated than necessary.

  22 to 24 exemplify the second embodiment of the present invention, and the elapsed time from the medal detection by the determination detection means 34 to the medal detection by the appropriate medal count detection means 33 is in an appropriate range (third appropriate range). An example is shown in which it is determined that the medal insertion is inappropriate on the condition that it is not within.

  As shown in FIG. 22, in the periodic interrupt process of the present embodiment, when the state of the detection means for determination 34 changes from ON to OFF (S29: Yes), 1 is added to the medal count number MCNT (S30). ) When the value of the medal count number MCNT after the addition is within the appropriate range (second appropriate range), that is, when the condition of MCNT> 5 is not satisfied, an initial value is set in the detection interval timer. (S31a) and the detection interval flag is set to ON (S31b).

  The initial value set in this detection interval timer is from medal detection by the determination detection means 34 (at the time of falling from ON to OFF) to medal detection by the appropriate medal count detection means 33 (second appropriate medal switch 62). Is set to a value corresponding to the allowable upper limit value of the elapsed time from the ON to the OFF fall). The allowable upper limit value may be set to a time slightly longer than the elapsed time when a proper medal is inserted. In the present embodiment, the allowable upper limit value of the elapsed time from the medal detection by the determination detection unit 34 to the medal detection by the appropriate medal count detection unit 33 is about 400 ms, and the initial value of the detection interval timer is 268 (≈400 / 1). .490) is set.

  In the subsequent periodic interrupt processing, if the state of the detection means for determination 34 has not changed from the previous OFF state (S29: No), the detection interval timer is set on condition that the detection interval flag is ON. Is subtracted (S29b), and if the timer value after the subtraction is 0 (S29c: Yes), the error flag is set to ON (S29d), and the periodic interrupt process ends.

  In the medal insertion detection process, as shown in FIG. 23, when the blocker solenoid 58 is turned OFF in S63 (S62: Yes → S63), it is determined that the proper medal has been normally inserted in S64. In this case (S65: Yes), the detection interval flag is set to OFF (S63a, S65a). Note that the medal insertion process including the medal insertion detection process and the periodic interrupt process are the same as those in the first embodiment.

  By performing the above processing, as shown in FIG. 24, after the medal detection by the determination detection unit 34, the medal detection by the appropriate medal count detection unit 33 is not performed within a predetermined time (about 400 ms). In this case (T61), the error flag is set to ON in S29d, and the error process is performed in S42 in the medal insertion process.

  In this way, the medal insertion is inappropriate on the condition that the elapsed time from the medal detection by the determination detection means 34 to the medal detection by the appropriate medal count detection means 33 is not within the appropriate range (third appropriate range). By further performing the process of determining that there is, it is determined to be inappropriate at the time when there is no detection by the next appropriate medal count detection means 33 even if a long time that cannot be normal after detection by the determination detection means 34 has elapsed. It is possible to judge and cheating can be eliminated more effectively.

  FIGS. 25 to 27 illustrate the third embodiment of the present invention, and show an example in which the detection means 34 for determination is provided, for example, in the vicinity of the medal sorting position A upstream from the non-permitted return position B. .

  As shown in FIGS. 25 to 27, in this embodiment, the detection means 34 for determination is arranged on the rear side in the vicinity thereof corresponding to the medal sorting position A, for example, mounted on the back side of the upstream cover plate 43. Has been.

  The configuration of the determination detection unit 34 is basically the same as that of the first embodiment. In other words, the detection means 34 for determination is retracted when the operating piece 63 protrudes toward the guide passage 31 and is pushed by a medal flowing down in the guide passage 31 so that the operating piece 63 faces the outside of the guide passage 31. The operating member 64 that can be changed to the operating state, and a determination switch 65 that detects that the operating member 64 is in the operating state are provided.

  The actuating member 64 is disposed, for example, on the back side of the upstream cover plate 43 and is supported so as to be rotatable about a substantially vertical axis, and from the rotary shaft portion toward the downstream side of the guide passage 31. A rotating arm portion 67 projecting from the distal end side of the rotating arm portion 67, and a working piece 63 projecting forward from the distal end side of the rotating arm portion 67, and a predetermined direction from the distal end side of the rotating arm portion 67, for example, downstream of the guide passage 31. For example, a detection piece 68 extending toward the surface is integrally provided.

  The operating member 64 includes a non-operating state in which the operating piece 63 protrudes toward the guide passage 31 through the through hole 69 ′ on the upstream cover plate 43 side, and the operating piece 63 outside the guide passage 31, that is, the rear side. And is urged elastically by the spring member 70 toward the non-operating state. It should be noted that the distal end side edge portion of the operating piece 63 is formed in an inclined shape in which the protruding amount toward the guide passage 31 gradually increases from the upstream side to the downstream side of the guide passage 31 when in the inoperative state. .

  The determination switch 65 is constituted by, for example, a transmission type photosensor, and is disposed at a position where the detection piece 68 is detected when the operation member 64 is in an operation state.

  The operating member 64, the determination switch 65, and the like are detachably mounted on the back side of the upstream cover plate 43 via one mounting frame 71.

  In this case, the determination detecting means 34 is arranged so as to detect medals downstream from the medal sorting position A, and only the medals that have not been removed from the guide path 31 at the medal sorting position A are detected for determination. It is desirable that detection is possible by means 34. In this case, the periodic interrupt process and the medal insertion process may be performed in the same manner as in the first embodiment.

  Further, the determination detecting means 34 is arranged so as to detect medals upstream from the medal sorting position A, and then all of them are detected regardless of whether or not they are removed from the guide path 31 at the medal sorting position A. May be configured to be detected by the detection means 34 for determination. However, in this case, for example, when an improper medal that is thicker than the appropriate medal is inserted, there is a case where the determination detection unit 34 is turned on, and the improper medal is continuously added, for example. Even when it is inserted, it should be noted that the value of the medal count number MCNT is added in S30 of the periodic interrupt process, and the error flag may be set to ON in S32.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the appropriate medal count detection means 33 may use various non-contact detection means other than a photo sensor, or a contact detection means that detects a medal based on a mechanical operation received from the medal. Also good. The appropriate medal count detection means 33 may be constituted by one or three or more switches.

  The determination detection means 34 may be composed of two or more switches. In this case, similarly to the appropriate medal count detection means 33, based on the detection signals from the plurality of switches, it is determined whether or not the detection signals satisfy a predetermined error detection condition, and the error detection condition is satisfied. If there is no medal detection by the detection means for determination 34, it may be determined that the medal has been detected.

  The five types of error determinations related to S23, S28, S32, S68, and S29d shown in the embodiment are preferably performed, but only one or more of them may be performed depending on the situation. Good.

  The determination conditions used for error determination, that is, the first to third appropriate ranges, etc. may be set to appropriate values according to the configuration of the medal sorting means 26 and the like.

  In the embodiment, the predetermined value X is added to the determination medal count value MCNT based on the medal detection by the determination detection means 34 (S30), and the determination medal count value based on the medal detection by the appropriate medal count detection means 33. Although the predetermined value X is subtracted from the MCNT (S66), the predetermined value X is subtracted from the determination medal count value MCNT based on the medal detection by the determination detection means 34, and the appropriate medal count detection means 33 A predetermined value X may be added to the determination medal count value MCNT based on medal detection.

  In this case, the first appropriate range may be −X × Y ≦ MCNT ≦ 0, and the second appropriate range may be −X × (Y + 1) −α ≦ MCNT. Further, the predetermined value X to be added to or subtracted from MCNT may be a value other than 1.

  In the embodiment, the switches 65 and 61 are arranged at positions where the determination switch 65 and the first appropriate medal switch 61 are not simultaneously turned on by one medal (see FIG. 17). 65 and the first appropriate medal switch 61 may be arranged at positions where they are simultaneously turned on by one medal.

  In S22 in the periodic interruption process (FIG. 13 and the like), it may be determined whether or not the medal reception is not possible, that is, whether or not the blocker solenoid 58 is OFF.

  The medal insertion detection process (FIG. 15) may be performed only when the blocker solenoid 58 is ON, that is, during a period other than during the medal unacceptable period. In this case, the periodic interrupt processing (FIG. 13 and the like) may be performed only when the blocker solenoid 58 is ON (when not in a medal acceptance period).

  The error flag is set to ON in S23, S28, S32, S68, and S29d. The error in the detection process (S64) of the detection signal of the appropriate medal count detection means 33 and the error related to the detection signal of the determination switch 65. Different error notification may be performed depending on the error in the case.

  If an error related to the detection signal of the determination switch 65 occurs, that is, if the error flag is turned on in S23, S28, S32, S68, S29d, error information is output to the outside without stopping the game. You may make it do. This would make it easier to detect fraudsters.

  In the embodiment, an example in which the present invention is applied to a slot machine has been described, but it goes without saying that the present invention can be similarly applied to any type of gaming machine as long as a medal is used as a gaming medium. .
