Therefore, even though the return ball preventing means 48 and the passage member 63 are connected to each other via the connecting portion 130, they can be easily arranged at appropriate positions regardless of the mounting positions on the other side.

FIG. 14 is a block diagram of a control system of the pachinko machine 1. In FIG. 14, the main control board 140 controls the game operation as a whole, and is composed of a normal symbol processing unit 141, a normal profit state generating unit 142, a special symbol processing unit 143, and a special symbol constituted by a CPU, a ROM, a RAM, and the like. The profit state generating means 144, the winning processing means 145, the ball detection processing means 146, the hitting number counting means 147, the base determination means 148, the control command transmission means 149, etc. are provided.

Various boards such as a production control board 150 and a payout control board 151 are connected to the main control board 140, and display means such as a normal symbol display means 64 and a special symbol display means 65, a normal symbol starting means 55, a special symbol starting means. 57, a big winning means 56, a normal winning means 54, a ball detecting means 49, etc. are connected.

The normal symbol processing means 141 is for performing a variable display process of the normal symbol of the normal symbol display means 64, and based on the normal symbol starting means 55 detecting the passage of the game ball, the normal random number information for hit determination is acquired. Then, the hit/off judgment is performed according to whether or not the obtained random number value matches a predetermined hit judgment value, and after the normal symbol fluctuates for a predetermined time, it is stopped with a stop symbol according to the determination result. To control.

The normal profit state generation means 142 is for generating a normal profit state that is advantageous to the player, and the stop symbol after the change of the normal symbol display means 64 is a hit mode based on the judgment result of the normal symbol processing means 141. When it becomes, the lower start winning means 57b of the special symbol starting means 57 is changed to an open state according to any one of a plurality of types of opening/closing patterns.

The special symbol processing means 143 is for performing variable display processing of the special symbol of the special symbol display means 65, and one of the upper starting winning means 57a and the lower starting winning means 57b of the special symbol starting means 57 detects the winning of the game ball. Based on that, the special random number information for jackpot determination is acquired, and the jackpot/outside determination is performed depending on whether the acquired random number value matches a predetermined jackpot determination value, and the special symbol is After changing for a predetermined time, it is controlled to stop with a stop symbol according to the determination result. In addition, the detection of the game ball of the special symbol starting means 57 can be reserved with the upper limit reservation number (for example, 4) as a limit.

The special profit state generation means 144 is for generating a special profit state that is advantageous to the player, and the stop symbol after the change of the special symbol display means 65 is the big hit mode based on the big hit judgment of the special symbol processing means 143. In this case, a special profit state in which the opening/closing member 56a of the special winning means 56 is opened/closed is generated according to a predetermined opening pattern.

The prize winning processing means 145 is for paying out prize balls according to the winning of the game balls to the special symbol starting means 57, the big winning means 56, and the normal winning means 54. The payout control board 151 is for controlling the payout means 152 according to the payout processing of the prize processing means 145, and the payout means 152 pays out a predetermined number of game balls to the upper plate 34 in accordance with the payout command of the payout control board 151. It is like this.

The sphere detection processing means 146 determines whether or not a game sphere is detected based on the sphere detection signal from the sphere detection means 49 and performs processing for preventing erroneous detection. The sphere detection determination means 155 and erroneous detection prevention means. 156 and.

The sphere detection determining means 155 determines that the game sphere is properly detected by the sphere detecting means 49 when the detection signal from the sphere detecting means 49 continues for a predetermined time X. As shown in FIG. 15A, the sphere detection determining means 155 uses the main loop 4 ms interrupt in the control system of the main control board 140 as a predetermined reference time t, and the sphere detecting means at each interrupt at each reference time t. The ball detection signal from 49 is read, and the interrupt when the ball detection signal changes from the L level to the H level is the first detection of the game ball, and the H level interrupt is a predetermined N times (for example, 4 times). Continuously, when the number of times of continuous detection is N, it is determined that one game ball has been detected at the Nth detection. Therefore, in the case of the number of detections N=4, in the case of the main loop 4 ms interrupt, the predetermined time X required for the ball detection determination means 155 to determine that one game ball has been detected is 12 ms≦X<16 ms. Become.

Even if the erroneous detection prevention means 156 determines that the sphere detection determination means 155 has detected one game sphere, as shown in FIGS. 15A and 15B, the sphere detection determination is the previous sphere detection determination. Therefore, if the dead time is within the predetermined dead time T, a process for outputting no detection output is performed as an erroneous detection due to chattering associated with the bouncing of the game ball.

That is, when the game ball hits the game area 42 and then the game ball collides with the ball collision top portion 66, the collision portion 78 and the like and bounces back toward the return ball prevention means 48 side, the return ball is caused by the impact. The prevention piece 86 rotates around the support shaft 88, a chattering phenomenon occurs in the sphere detection means 49 via the return sphere prevention piece 86, and the sphere detection means 49 continuously outputs a detection signal for a predetermined time X, The detection determination means 155 may erroneously determine that a game ball has passed.

Therefore, the dead time T is set in the erroneous detection prevention unit 156, and the number of continuous detections becomes N times within the dead time T from the previous ball passage determination, and the ball detection determination unit 155 determines the ball detection. Even if there is, the erroneous detection prevention unit 156 does not output as the erroneous detection due to chattering in the ball passage determination.

The dead time T is calculated as T=T1-T2-T3-T4. Here, T1 is the detection interval of the game ball of the ball detection means 49, which is substantially the same as the interval of the game ball emitted by the emission means 17. Therefore, when the maximum number of shots is 100 per minute, T1=600 ms. T2 is the variation in the detection time when the ball detection means 49 detects a game ball. Even when a game ball is shot in a state where the launching strength of the launching means 17 is kept the same, the detection time has a variation of about 9 ms, and the variation of the time is T2.

T3 is the minimum detection interval time. For example, as shown in FIG. 16A, even when the game balls are shot at regular time intervals, the game balls are concentrated in the left hitting passage 38 at the time of right hitting, where the game balls are concentrated in the right hitting passage 39. The strength at which the game ball is launched is greater than when left-handed. Therefore, when transitioning from the left-handed state to the right-handed state, as shown in FIG. 16B, after the ball detection means 49 detects the game ball at the time of the previous left-handed hit, the time of the next right-handed hit The time interval until the game ball is detected becomes shorter. Therefore, it is necessary to consider the difference in the time intervals as the minimum detection interval time T3.

By the way, when the time interval was confirmed by an experiment, it was found that there was a difference of about 152 ms in the time until the ball detecting means 49 detects the game ball due to the difference in the firing intensity between left hitting and right hitting. ..

The minimum detection interval time T3 can be replaced with the maximum chattering time. Because, due to the difference in the launch strength between left hitting and right hitting, the game ball that collides with an obstacle or the like bounces off the return ball preventing means 48, and the ball detecting means 49 passes through the return ball preventing means 48. This is because it can be regarded as the maximum chattering time until the game ball is detected. T4 is the worst value of the variation in the detection range of the ball detection means 49, and is the minimum time required from the elapse of the insensitive time T in calculation to the detection of the next game ball.

By setting the refractory time T in this way in the false detection preventing means 156, false detection due to chattering of the game ball can be surely removed, and the subsequent ball detection signal is driven into the game area 42. Match the number of balls in the game ball. Therefore, when counting the number of game balls that have been driven into the game area 42 by the number-of-drives counting means 147, it is possible to perform highly reliable counting excluding erroneous detections due to chattering.

Based on the winning signal from the winning processing means 145 and the number of hits from the driving number counting means 147, the base determination means 148 wins the gaming ball in the normal game and the gaming ball paid out by the payout means 152. The ratio between the number of payouts and the number of game balls used in the game is calculated, and the base output 148a is output as necessary. It should be noted that the number of game balls to be driven may be utilized for other processing than the base determination.

The control command transmitting means 149 is for transmitting a control command to the sub control board such as the effect control board 150, and based on the special symbol processing of the special symbol processing means 143, a control command relating to the special symbol, a special profit state occurrence. The production commands related to the generation of the means 144 are transmitted to the production control board 150, respectively.

The effect control board 150 is for controlling various effect means including the image display means 50, the speakers 18, 31, 32, and the like. The effect control board 150 is provided with effect symbol control means 158 for controlling the effect symbol display means 52 of the image display means 50.

The effect symbol control means 158 controls the variation of the effect symbol of the effect symbol display means 52, and based on the control command from the main control board 140, in synchronization with the special symbol of the special symbol display means 65, the effect symbol display. The effect design of the means 52 is changed in a predetermined change pattern for a predetermined time and is controlled to stop at a predetermined stop design.

In the game, when the player turns the firing handle 36 to fire a game ball with a predetermined firing strength, the game balls from the upper plate 34 are supplied to the launch rail 21 of the launching means 17 one by one by the ball feeding means. Then, the game ball is shot to the game board 16 side by the batting mallet 24 driven by the firing drive means 25.

The game ball launched by the launching means 17 is guided to the upper side through the ball guide passage 45 between the inner and outer guide rails 43, 44, and on the return ball preventing piece 86 of the return ball preventing means 48 on the ball outlet 47 side. It passes and is driven into the upper part of the game area 42. Then, the game ball in the game area 42 flows downward through either the left-handed passage 38 on the left side or the right-handed passage 39 on the right side of the center case 51, while the normal symbol starting means 55, the normal winning means 54, Either the special symbol starting means 57, the big winning means 56, or the like is won, or it is discharged to the back side of the game board 16 through the bottom outlet without winning.

In the return ball prevention means 48, the return ball prevention piece 86 is normally held at the return ball prevention position D by the weight 104 of the biasing means 87. Then, when the game ball passes through the return ball prevention means 48, the game ball collides with the return ball prevention piece 86, and the inertial force of the game ball causes the return ball prevention piece 86 to be indicated by the arrow e around the support shaft 88. Since it rotates in the direction, the game ball is driven into the upper part of the game area 42 through between the return ball prevention piece 86 and the outer guide rail 43.

After the game ball passes through the return ball prevention piece 86, the return ball prevention piece 86 is rotated around the support shaft 88 in the direction opposite to the arrow e direction by the bias of the weight 104 and returns to the return ball prevention position D. Therefore, even if a game ball hit in the game area 42 collides with the center case 51 or the collision portion 78 of the passage member 63 and the like and the game ball bounces in the opposite direction to the ball outlet portion 47 side, that game ball is also played. The ball only collides with the return ball prevention piece 86 in the standing state at the return ball prevention position D on the side of the ball outlet portion 47 and flows down to the left striking passage 38, and the game ball is guided from the ball outlet portion 47 to the ball. It is possible to prevent returning to the passage 45.

On the other hand, when the return ball prevention piece 86 rotates around the support shaft 88 in the direction of the arrow e, the detected portion 102 rotates together with the return ball prevention piece 86 to receive light from the light projecting portion 116 of the ball detection means 49. Since it is separated from the section 117, the light receiving section 117 receives the light from the light projecting section 116, and the signal of the light receiving section 117 becomes H level. When the return ball prevention piece 86 returns to the return ball prevention position D, the detected portion 102 enters between the light projecting portion 116 and the light receiving portion 117 to shield the light, so that the signal of the light receiving portion 117 is at the L level. Becomes Therefore, the signal of the light receiving section 117 continues to be at the H level for a certain period while the detected section 102 is out of the space between the light projecting section 116 and the light receiving section 117.

Even if the game ball hit in the game area 42 collides with the collision portion 78 or the like and bounces back to the return ball prevention piece 86 side, if the game ball collides with the return ball prevention piece 86, the return ball is caused by the impact. Since the preventive piece 86 vibrates around the support shaft 88, the ball detecting means 49 may detect chattering of the return ball via the return ball preventive piece 86. However, the chattering of the sphere detecting means 49 due to the returning sphere can be eliminated by the erroneous detection preventing means 156 as described later.

At the time of left hitting, after the game ball hits the hitting portion 78 of the ball driving part 77 of the passage member 63 or the like, the game ball flows down the left hitting passage 38 downward. At that time, the game ball that collides with the collision section 78 may bounce back to the lower part of the return ball prevention means 48, especially to the support member 85 side. However, even if there is a game ball that bounces back to the support member 85 side without interruption, since the collision prevention walls 120 and 121 are arranged along the support member 85 on the left striking passage 38 side, inside the left striking passage 38. The game sphere that flows down only collides with the collision prevention walls 120 and 121, and does not collide with the inner support wall portion 95 of the support member 85. Therefore, the impact due to the collision of the game ball on the left hitting passage 38 side can be received by the collision prevention walls 120 and 121, and the damage due to the collision of the game ball with the support member 85 can be prevented.

Further, the support member 85 of the return ball prevention means 48 and the passage rear wall portion 71 of the passage member 63 are separately fixed to the front surface of the game board 16, and the support member 85 and the passage rear wall portion 71 have play. Since they are connected via the connecting portion 130, the impact of the collision prevention walls 120 and 121 does not propagate to the supporting member 85 side of the return ball preventing means 48 via the connecting portion 130. Therefore, the sphere detecting means 49 does not become unstable and malfunction due to the vibration of the supporting member 85 side.

When the ball detecting means 49 is damaged, the pressing side member 91 may be removed and the substrate 89 may be pulled out from the base side member 90 side to the front side. In this case, when the attaching screw 100 of the pressing-side member 91 is removed, the pressing-side member 91 is pulled out from the support shaft 88 forward, so that the substrate 89 can be easily removed. Therefore, the return ball prevention piece 86 may be rotated around the support shaft 88 to a position where the detected portion 102 is separated from the ball detection means 49, and in that state, the substrate 89 may be pulled out to the front side.

Although the external connector 113 of the harness 112 is connected to the board-side connector 111, the length of the harness 112 from the locking portion 114 to the external connector 113 is provided with a margin for extracting the board 89 to the front side. In other words, the external connector 113 may be removed from the board-side connector 111 after the board 89 is pulled out to the front side.

When replacing the substrate 89 with the new ball detecting means 49, insert the substrate 89 into the base side member 90 side in the reverse order, and assemble so that the pressing side member 91 supports the substrate 89 and the support shaft 88. Good.

The return ball prevention means 48 including the ball detection means 49 and the passage member 63 are in a state of being connected to each other through the connection portion 130, and therefore, before the game board 16 is mounted, the return ball prevention means 48 including the return means including the ball detection means 49 is provided. The entire ball prevention means 48 and the passage member 63 can be handled as a single game component, and the management of the game components can be facilitated.

When assembling the center case 51, the passage member 63, the return ball prevention means 48 and the like to the game board 16, first the passage member 63 and the return ball prevention means 48 are attached to the game board 16 and then the passage of the passage member 63 The center case 51 is attached to the game board 16 so that the outer peripheral edge of the center case 51 contacts the front end side of the peripheral wall portion 72 from the front side.

When attaching the passage member 63 and the return ball prevention means 48, the passage member 63 is placed at a predetermined position on the game board 16 by the positioning projection (not shown) of the passage rear wall portion 71, and the return ball prevention means 48 is provided by the support member 85. After positioning the positioning protrusions 126 at predetermined positions on the game board 16, the mounting screws 76 and 127 are tightened to fix the passage rear wall portion 71 and the support member 85 to the game board 16.

In this case, the return ball prevention means 48 is arranged at an optimum position with respect to the inner and outer guide rails 43 and 44 so that the return ball prevention piece 86 allows the game balls to pass smoothly and surely prevents the return balls. In addition, the passage members 63 are fixed to the optimum positions for forming the left-handed passage 38, respectively. At this time, even if there is some variation between the mounting position of the return ball prevention means 48 and the mounting position of the passage member 63, the connection portion 130 of the return ball prevention means 48 and the passage rear wall portion 71 of the passage member 63 are not connected. Since there is a predetermined play between the return ball prevention means 48 and the passage member 63, if the return ball prevention means 48 and the passage member 63 are within the play range, the return ball prevention means 48 and the passage member 63 are separated from each other. Can be installed in the optimum position.

Further, the return ball prevention means 48 including the ball detection means 49 and the passage member 63 are in a connected state through a predetermined play before being mounted on the game board 16, so that the return ball prevention is within the play. Each of the means 48 and the passage member 63 can be arranged in a predetermined position. Therefore, even though the return ball preventing means 48 and the passage member 63 are connected to each other via the connecting portion 130, they can be easily arranged at appropriate positions regardless of the mounting positions on the other side.

When the game ball in the ball guide passage 45 passes the return ball prevention means 48, the game ball contacts the return ball prevention piece 86, so the return ball prevention piece 86 supports against the bias of the biasing means 87. Once around the shaft 88, it rotates in the direction of the arrow e, and after the game ball has passed, the return ball prevention piece 86 is returned to the return ball prevention position D by the urging of the urging means 87.

Interlocked with the reciprocating movement of the return ball prevention piece 86 around the support shaft 88, when the return ball prevention piece 86 rotates in the direction of the arrow e, the detected portion 102 and the light projecting portion 116 of the ball detecting means 49 are connected. When the return ball prevention piece 86 is rotated in the direction indicated by the arrow e after being separated from the light receiving section 117, the detected section 102 returns between the light projecting section 116 of the ball detecting means 49 and the light receiving section 117. To do. Therefore, the light receiving section 117 receives the light from the light projecting section 116 for a predetermined time when the detected section 102 is apart from the light projecting section 116 and the light receiving section 117, and the output of the light receiving section 117 is shown in FIG. As shown in the figure, the L level in the light shielded state changes to the L level in the light shielded state through the H level in the light receiving state. Then, when the game ball passes through the return ball prevention means 48, the H level of the detection signal of the light receiving section 117 continues for a predetermined time X.

Therefore, for the game sphere detection processing, as shown in FIG. 17, the sphere detection determination means 155 always reads the sphere detection signal from the sphere detection means 49 (S1), and the sphere detection signal is the main. In the loop 4 ms interrupt, it is confirmed for each interrupt whether or not it is at H level (S2). Then, when the sphere detection signal at the time of interruption is at the H level as the first detection, +1 is sequentially added to the counter every time the sphere detection signal at the time of interruption is at the H level (S3).

If the sphere detection signal is not at the H level for each interrupt (S2), it is determined whether or not the H level has been detected by that time (S4). If there is, the counter is cleared (S5). The process returns to the reading of the ball detection signals respectively (S1).

Next, it is confirmed whether or not the number of times the ball detection signal at the time of each interruption is at the H level is four times (S6). If the number of detection times is four, the ball detection signal from the ball detection means 49 is played. A sphere detection determination signal indicating that one sphere has been detected is output (S7).

Therefore, if the H level of the ball detection signal from the ball detection means 49 continues for a predetermined time X, and the number of times the H level is detected 4 times from the first detection of the H level, the ball detection determination means 155 is a game ball. Output the detection judgment signal. Therefore, when the foul ball in the ball guide passage 45 temporarily contacts the return ball prevention piece 86 and the ball detection means 49 operates for a short time, due to abnormal vibration of the return ball prevention piece 86 due to a beating of the player or the like. In the case where the sphere detecting means 49 works intermittently in a short time, the sphere detection determining means 155 can eliminate it as an abnormality detection.

For example, the game ball in the ball guide passage 45 reaches the ball outlet portion 47 while stalling, lightly contacts the return ball prevention piece 86 of the return ball prevention means 48, and then returns to the ball guide passage 45 downward as a foul ball. Even in such a case, the return ball prevention piece 86 is rotated around the support shaft 88 by the contact with the game ball, and the light receiving portion 117 of the ball detection means 49 is interlocked with the reciprocating operation of the return ball prevention piece 86. The output may change from L level to H level and then to L level.

However, in such a case, unlike when the game ball is passed, the reciprocating operation time of the return ball prevention piece 86 is extremely short, and the number of H-level detections is less than 4, so the ball detection means 49 is Even if the game ball is detected, the ball detection determination means 155 does not determine that the game ball is detected, and does not output the ball detection determination signal of the game ball.

When the launching strength of the launching means 17 is high, the game ball hit in the game area 42 may bounce back to the return ball preventing means 48 side after colliding with the top of the center case 51 and other places. However, since there is a return ball prevention means 48 on the ball outlet 47 side of the ball guide passage 45, it only collides with the return ball prevention piece 86, and the game ball becomes a return ball and the ball guide passage 45. There is no entry to.

On the other hand, when the bouncing game ball collides with the return ball prevention piece 86, the impact causes the return ball prevention piece 86 to reciprocate around the support shaft 88 to operate the ball detection means 49, which causes the ball detection means 49 to emit at a normal interval. A chattering phenomenon may occur in which the detection signal is output at a shorter interval. However, such chattering due to the bouncing of the game sphere occurs within the dead time T of the erroneous detection preventing means 156, and therefore can be removed by the erroneous detection preventing means 156 as an erroneous detection.

Therefore, despite the configuration that the passage of the game ball to the game area 42 is detected through the operation of the return ball prevention piece 86, it is possible to prevent the malfunction due to the bouncing of the game ball from the side of the game area 42, and the number of hits. The counting means 147 can count the actual number of game balls actually hit in the game area 42.

That is, when the sphere detection determination means 155 detects the fourth detection number and makes the sphere detection determination (S7), whether the time from the previous sphere detection determination to the current sphere detection determination is within the dead time T. It is confirmed (S8). Then, if the time until the present ball detection determination is not within the dead time T, a ball detection output is output assuming that a regular game ball is detected (S8). If the time until the present ball detection determination is within the dead time T, the ball detection means 49 has acted due to chattering when the rebound ball collides with the return ball prevention piece 86, and the subsequent ball detection determination is It is not output as an erroneous detection (S10).

FIG. 18 illustrates a second embodiment of the present invention. In this embodiment, the collision prevention wall 120 arranged near the inner support wall portion 95 of the return ball prevention means 48 is continuous in the vertical direction. Thus, the collision prevention wall 120 may be provided. Therefore, it is not always necessary to separately provide the upper and lower collision preventing walls 120 and 121 as the passage rear wall portion 71 and the pressing side member 91 as in the first embodiment.

19 and 20 illustrate a third embodiment of the present invention. In this embodiment, the passage member 63 and the return ball prevention means 48 are separately mounted on the game board 16. A collision prevention wall 120 is integrally provided on the passage rear wall portion 71 of the passage member 63 in the vicinity of the inner support wall portion 95 of the return ball prevention means 48 along the inner support wall portion 95. Other configurations, such as the sphere detecting means 49 incorporated in the return sphere preventing means 48, are substantially the same as those in the first embodiment.

In this case, since the passage member 63 and the return ball prevention means 48 are independent, they are separately mounted at predetermined positions on the game board 16, but the collision prevention wall 120 allows the return ball prevention means 48 to play. The same effect as that of the first embodiment can be obtained, such as the collision of the ball can be prevented and the impact applied to the collision prevention wall 120 does not propagate to the return ball prevention means 48 side.

FIG. 21 illustrates a fourth embodiment of the present invention. In this embodiment, in the sphere detection processing by the sphere detection processing means 146, the insensitive processing is performed prior to the processing of the detection determination of the game sphere, and even if there is a sphere detection signal from the sphere detection means 49, the previous sphere is detected. If the time from the detection determination is within the dead time T, the sphere detection process is not performed.

If there is a sphere detection signal from the sphere detection means 49 (S1), it is determined whether the time from the previous sphere detection determination is within the dead time T (S11). Then, if the ball detection signal this time is within the dead time T, the dead detection process is performed assuming that the ball detection means 49 has worked due to chattering when the rebound ball collides with the return ball prevention piece 86 (S12). ..

If the time until the current ball detection signal is not within the dead time T (S11), it means that the ball detection means 49 has detected the game ball by a phenomenon other than the chattering phenomenon. Confirm (S2). Then, when the sphere detection signal at the time of interruption is at the H level as the first detection, +1 is sequentially added to the counter every time the sphere detection signal at each interruption is at the H level (S3).

If the sphere detection signal is not at the H level for each interrupt (S2), it is determined whether or not the H level has been detected by that time (S4). If there is, the counter is cleared (S5). The process returns to the reading of the ball detection signals respectively (S1).

Next, it is confirmed whether or not the number of H-level detections for each interrupt is four times (S6), and if the number of detections is four, the ball detection signal from the ball detection means 49 detects one game ball. The sphere detection determination signal is output (S7), and the driving number counting means 147 counts the number of game spheres driven for each sphere detection determination (S13).

In this way, in the ball detection process, if there is a ball detection signal from the ball detection means 49, insensitive processing is performed prior to the processing of game ball detection determination, and the time from the previous ball detection determination is the dead time. If it is within T, the sphere detection processing may not be performed, and if the time from the previous sphere detection determination is outside the dead time T, the sphere detection determination processing may be performed. In this case, it is not necessary to perform the sphere detection determination for each sphere detection signal, so that the processing can be simplified.

Although the respective embodiments of the present invention have been described above in detail, the present invention is not limited to the respective embodiments, and various modifications can be made without departing from the spirit of the invention. In the embodiment, the pachinko machine 1 is exemplified, but the pachinko machine 1 and other game machines such as a ball game machine and an arrangement ball machine can be similarly implemented.

In the first embodiment, the return ball prevention means 48 and the passage member 63 are connected to each other via the connecting portion 130 having a play, but as long as they can be mounted on the game board 16 from the front side, other than the passage member 63. It may be one. Further, when the ball detection means 49 detects a game ball through the operation of the return ball prevention piece 86 of the return ball prevention means 48, it is desirable to incorporate the ball detection means 49 into the return ball prevention means 48, but the ball detection means. It is also possible to provide 49 separately from the return ball prevention means 48.

The ball detecting means 49 can directly detect the game ball without using other members such as the return ball preventing means 48. In that case, a sensing piece may come into contact with the game ball passing through the ball outlet portion 47, and a contact type in which the gaming ball is detected via the sensing piece may be adopted, or an optical non-contact type game ball may be used. You may make it detect.

The biasing means 87 for biasing the return ball prevention piece 86 to the return ball prevention position D is the weight 104 in the embodiment, but a spring or the like may be used instead of the weight 104.

In the embodiment, the connection member 130 of the support member 85 of the return ball prevention means 48 is interposed between the passage member 63 and the attachment portion 122 of the collision prevention wall 121 detachably attached to the passage member 63, and Although the support member 85 of the return ball prevention means 48 is connected, another connection structure may be adopted. Further, the play of the connecting portion 130 may be configured by other means.

The sphere detection determining means 155 determines that the game sphere is detected when the sphere detection signal of the sphere detecting means 49 continues to be at the H level (ON state) for a predetermined time X, but the predetermined time X is the peripheral. It may be appropriately determined according to the conditions. Alternatively, it may be determined that a game ball has been detected when the L level (off state) continues for a predetermined time X.

The ball detection determination means 155 uses the time interval at the time of interruption of the main loop as a reference, and determines that a game ball has been detected when the ball detection signal for each interrupt has been turned on for a predetermined number of times. The time may be a time interval other than the interrupt time.

In the embodiment, the dead time T is a predetermined time after the ball detecting means 49 passes through the game ball, and the game ball detection output is not output during the dead time T. T may be appropriately determined according to the surrounding conditions. Further, the insensitive time T is a chattering time required from the launch ball detection interval for detecting the game ball from the launching means 17 to the return of the launch ball to the ball detecting means 49 side at least after the launch ball is detected by the ball detecting means 49 or It may be the time obtained by subtracting the minimum time between firings. Further, a ball game machine other than the pachinko machine 1, a game machine such as an arrangement ball machine can be similarly implemented.
