Description

The present invention relates to a pachinko machine that detects a winning ball during a power failure.

In current pachinko machines, the control device regularly monitors detection signals from sensors (for example, winning ball detection means, winning ball detection means) provided in the machine, while controlled devices (for example, , Winning devices, display devices, discharge units, etc.) are controlled to advance the game. For this reason, when a power failure occurs, an interrupt signal is generated from the power supply voltage detection device to ensure the time for storing data in the control device (5V) such as a CPU and the operation of various switches (12V). . This time depends on the discharge time of the charge stored in the capacitors provided in each power supply after a power failure, and is secured for at least 0.1 second (see Patent Document 1). However, for example, in a 2-type pachinko machine (so-called feather pachinko machine), immediately after a power failure, if a player enters a blade object and then enters a V prize opening (special prize opening), he enters the blade object. Since it takes time to win the V prize opening after the power outage, it is possible to detect the blade entry after a power outage with the sensor, but it is not possible to detect the ball entry into the V prize opening with the sensor. Become. In order to avoid such an inconvenience, it is conceivable to increase the capacity of the capacitor. However, there is a disadvantage that the capacitor becomes large and it takes a long time to rise after power recovery.

On the other hand, as a detection of the ball entering the V winning opening during a power failure, the closing stop member is displaced by a solenoid in front of the sensor detecting port of the V winning port immediately after the power failure, and the winning ball is stopped in front of the sensor detecting port, An invention has been disclosed in which a closed stop member is opened after power recovery to detect a ball entering a V prize opening (Patent Document 2). However, the mechanism of the closed stop member and the solenoid is necessary in addition to the sensor, and increasing such moving parts may cause a failure.

The game flow of the pachinko machine 1 is described in FIG. When the player operates the launching handle 7 at the lower front of the pachinko machine 1 to launch a game ball on the game board 5, the game ball flows down the game board 5 while the general winning ports 33 to 36, chuckers L, R, Although there are some that win M, most of them are missed and discharged from the outlet 39. Here, the winnings in the general winning openings 33 to 36 are detected by the winning sensors 33 s to 36 s, and a predetermined number, for example, ten winning balls are paid out. Those winning the chuckers L, R, and M (S1) are detected by the incoming sensors Ls, Rs, and Ms, and a predetermined number, for example, five award balls are paid out. It is determined whether or not the chucker M has been won (S2), and if the determination is YES, a blade opening game is performed in which the movable members F1 and F2 of the blades are continuously opened twice at intervals of 1 second for 0.65 seconds. (S4). If the determination is NO, it is determined that the prize has been won for chuckers L and R, and a blade opening game is performed in which the blade movable members F1 and F2 are opened once for 0.35 seconds (S3). At the same time, a lottery for the number of rounds is executed in advance (S5). In the lottery for the number of rounds, the lottery for distributing 1, 3, and 15 rounds by 1/3 is performed, but the probability of the lottery may be changed as appropriate. Whether or not the winning space 21 has been entered is determined by the left and right entrance sensors C1 and C2 based on the opening of the movable members F1 and F2 (S6). If there is no entry, the flow of the feather opening game by the chucker winning is finished. If there is a ball, it is further determined whether the ball has entered the specific winning port 30 of the distribution device 32 or the normal winning port 31 (S7). In this case, 10 prize balls are paid out and the game shifts to jackpot game execution (S8). In the jackpot game, the movement of opening the movable members F1 and F2 of the blades for 0.65 seconds per round can be executed with a maximum of 18 wins or 10 balls at an interval of 1 second. When the ball enters, the round is continued, and ends with an upper limit on the number of rounds drawn. When the player has entered the normal winning opening 31 (NO in S7), 10 winning balls are paid out, and the game flow ends.

FIG. 5 is a conceptual diagram of the embodiment of the present invention of the distribution device, the winning path, and the arrangement of the ball sensor. In addition, the sensor box etc. which support the entrance sensor 30s are abbreviate | omitted from this figure for clarification of a concept. The distribution device 32 that distributes the special winning opening 30 to which the bonus game bonus is given and the normal winning slot 31 to which the bonus game bonus is not given is provided with two normal winning slots 31 and one specific winning slot 30 for the allocation. In the lower part of the device 32, the normal winning passages 40 of the two normal winning openings 31 are combined into one and connected to a back mechanism board (not shown). One specific prize opening 30 is provided with a ball entry sensor 30s for detecting a ball entry in the specific prize passage 41, and is connected to a back mechanism board (not shown). The normal winning award passage 40 and the specific winning award passage 41 are gently inclined from the front to the back side, and the game ball P does not stay in the winning passage and does not stay in the winning aisle even after touching the winning sensor 30s. It moves to the back mechanism board. In the embodiment of the present invention, the ball entry sensor 30s is provided only in the specific winning award passage 41 connected to the specific winning award 30 to which a bonus game bonus is given, but also in the normal winning award passage 40 connected to the normal winning award 31. An incoming ball sensor 31s may be provided. Since the number of game balls that have entered the winning space 21 can be detected by the winning sensors C1 and C2, if the winning sensor 30s is provided at least in the specific winning passage 41 connected to the specific winning opening 30, the normal winning opening 31 This is because the number of game balls that have entered the ball can be finally detected even if there is a time error.

6A and 6B are perspective views of the incoming ball sensor 30s, which is a feature of the present invention. FIG. 6A is a perspective view from the detection unit side, and FIG. 6B is a perspective view from the opposite side to the detection unit. It is. As will be described later, the winning sensor 30s is provided with a mechanism for supporting the rotating shaft above the winning path, and is mechanically rotated by contact with the game ball P rolling in the winning path. The main part of the incoming ball sensor 30 s includes a rotating body 43 that rotates in contact with the game ball P, a shaft body 44 that transmits the rotation of the rotating body 43, and a detection unit 45 provided in a part of the shaft body 44. (See FIG. 6A). In the present embodiment, since the rotation at a predetermined angle is set to 90 degrees, the rotating body 43 is cut so that the four corners are in contact with the game ball P. If the radius of curvature of the shaved portion is slightly larger than the radius of curvature of the game ball P (5.5 mm), sufficient contact with the game ball P can be ensured. In addition, in order to allow only rotation in one direction of the rotating body 43 and to prevent return, a 90 ° -notch is provided in the disk fixed to the rotating body 43 or the shaft body 44 so that the notch is gradually eliminated. A disk 46 having a notch formed on the disk 46 and a plate 47 that is supported by one axis and moves up and down in contact with the circumference of the disk 46 are added. The disk 46 and the plate 47 constitute means for restricting rotation in one direction.

Further, as shown in the perspective view on the opposite side to the detection unit, the spring biasing member 49 and the rotating body 43 or the rotation body 43 or A predetermined angle rotation setting means is constituted by a disk 48 having notches at four corners fixed to the shaft body 44. The spring biasing member 49 includes an upper spring pressing portion 50, a lower spring pressing portion 52 fixed to the support shaft 53, a spring 51 sandwiched therebetween, and a rotating roller 54 provided at the tip of the support shaft 53. . The disk 48 in which the rotating roller 54 is in contact with the circumferential surface has a circumferential surface formed so that the spring 51 extends most when rotated 90 degrees, and the spring 51 contracts most when rotated 45 degrees. The pushing force generates an oblique force on the surface where the rotating roller 54 and the disk 48 are in contact with each other, thereby generating a rotation moment. Therefore, when the rotating body 43 in contact with the game ball P rotates 45 degrees or more, the rotating body 43 automatically rotates 90 degrees using the energy stored in the spring and is stabilized at that position. It will be.

FIG. 7 is a view showing a state in which the game ball P is in contact with the rotating body of the entrance sensor 30s and progresses. 7A is a diagram immediately before contact, FIG. 7B is a diagram in the middle of contact, and FIG. 7C is a diagram immediately before the contact is released. The rotation of the rotating body 43 at a physical angle not caused by the spring biasing member 49 due to the contact with one game ball P corresponds to the radius r of the rotating body 43 and the thickness of the rotating body 43 in the rotation direction. It can be calculated from α, the distance L from the specific winning path 41 at the center of the rotating body 43, and the radius d (usually 5.5 mm) of the game ball P. Assuming that the radius of the rotating body 43 is r = 6 mm, the angle α = 7 degrees, and L = 15 mm, the rotation θ of the contact point from the contact start to the contact release can be obtained by cos θ = (L−2d) / r. The rotation of 43 physical angles (θ + α) is found to be about 55 degrees. This angle is well above 45 degrees, and the rotating body 43 continues to rotate further by the spring biasing member 49 and the disk 48 even after the contact with the game ball P is released, and automatically reaches a predetermined angle of 90 degrees. Rotate and stop there.

FIG. 8 shows a view in which the winning sensor 30 s is arranged in the specific winning path 41. A part of the upper part of the specific winning path 41 has an opening 60 through which a part of the rotating body 43 of the winning sensor 30s enters the winning path. Further, it is configured by a sensor box that covers the opening 60 and supports the shaft body 44 of the ball sensor 30s. The side of the sensor box
It consists of side surfaces 61 and 62 that support the shaft body 44, and the upper surface is composed of an upper wall 63, the upper part of the spring biasing member 49 can project, and the upper spring pressing part 50 is provided with a small hole that cannot project. The upper spring pressing portion 50 is pressed to cause the spring 51 to be biased. Further, a support shaft 64 that supports the plate 47 uniaxially extends from the side surface 61. There may or may not be a side surface of the sensor box in the rolling direction of the game ball. Further, shaft stabilizing ring members 55 and 56 for preventing the shaft body 44 from shaking in the axial direction are provided on the inner surface sides of the side surfaces 61 and 62 of the shaft body 44 of the incoming ball sensor 30s.

FIG. 9 shows an enlarged perspective view of the detection unit 45 of the incoming ball sensor 30s. The detection unit 45 is provided in a part of the shaft body 44. In the present embodiment, the circumference of the shaft body 44 is divided by 90 degrees, and the conductors 70 and 71 are attached to necessary portions. By turning ON / OFF the conduction between the electrode pair 72, 73 and the electrode pair 74, 75, two bits of the upper bit and the lower bit can be detected so that four count values corresponding to rotation by 90 degrees can be detected. It has become. The electrode pairs 72, 73 and the electrode pairs 74, 75 are bent so that the tip portions are in light contact with the shaft body 44, and the conductors 70, 71 are interposed between the electrode pairs 72, 73 and the electrode pairs 74, 75. Continuity is detected when rotating. For example, as shown in FIG. 10, when the count value is 0, since there are no conductors 70 and 71 at the portions of the electrode pairs 72 and 73 and the electrode pairs 74 and 75, there is no continuity and both the upper and lower bits are detected. The applied voltage becomes 0V L level. When the count value is 1, there is no conductor 71 at the electrode pair 72, 73, but there is the conductor 70 at the electrode pair 74, 75, so the upper bit is not conductive and the voltage is 0V. Since the lower bit is conductive, the voltage is detected at the H level of Vcc. When the count value is 2, since the conductor 71 is present at the electrode pair 72 and 73 and the conductor 70 is absent at the electrode pair 74 and 75, the upper bit is conductive, so the voltage is H at Vcc. Since the lower bit is not conductive, the L level of 0V is detected. When the count value is 3, since the conductor 71 is present at the electrode pair 72 and 73 and the conductor 70 is present at the electrode pair 74 and 75, both the upper and lower bits are conductive and detected. The voltage of both the upper and lower bits is at the H level of Vcc. In this way, rotation by 90 degrees can be detected with a simple device.

In the present embodiment, four count values are detected in order to detect rotation by 90 degrees. However, in order to increase the count value, the rotation angle may be reduced. For example, in order to detect six count values, it is sufficient to detect rotation by 60 degrees. However, if the angle is small, it is not preferable because the rotating body 43 that contacts the game ball P needs to be enlarged. Further, the detection unit 45 is directly provided on the shaft body 44, but a gear box is provided between the rotating body 43 and the shaft body 44 or between the shaft body 44 and the detection unit 45, and the detection unit 45 is provided. It is also possible to detect this by increasing or decreasing the rotation angle as appropriate. Further, instead of detecting rotation by electrical conduction, it is also possible to detect the rotation of the rotating body 44 using a rotary encoder using magnetism or the like as the detection unit 45.

The voltage detected by the ball entry sensor 30s provided in the specific winning path 41 of the specific winning opening 30 is input to the counter IC via the Schmitt trigger circuit in order to remove the influence of noise and the like, and the count value Is sent to the CPU of the main control unit MC via the I / O port 1 of the control unit CN. The CPU of the main control unit MC stores the count value in a storage means such as a RAM every predetermined time by software interruption, determines whether there is a change between the previous count value and the current count value, and the change is In some cases, it is determined that there has been one pitch in the specific winning slot 30, and thereafter, ten prize balls are paid out to instruct the execution of the jackpot game.

The detection of a ball entering the specific winning opening 30 during a power failure, which is an advantage of the present invention, will be described below. In order to detect entry during a power failure, it is necessary to store the rotation angle or count value of the entrance sensor 30s during power failure processing. As described above, the RAM of the CPU of the main control unit MC stores and holds the stored value of the value related to the rotation angle of the entrance sensor 30s at the time of the power failure process by the backup capacitor even during the power failure. Therefore, when the CPU of the main control unit MC is stopped due to a power failure and there is one ball in the specific winning opening 30, the rotating body 44 is rotated 90 degrees by the game ball P, and the rotation angle of the ball sensor 30 s is It will increase 90 degrees from the rotation angle of the incoming ball sensor 30s during the power failure process. Thereafter, when the power failure is restored and the power restoration processing is performed, the CPU of the main control unit MC restores the rotation angle or the count value of the incoming ball sensor 30s stored in the RAM at the time of the power failure processing, and after the power restoration The rotation angle or count value of the incoming ball sensor 30s is read. Since the stored value of the rotation angle of the storage means at the time of the power failure process and the rotation angle of the storage means after the power recovery process are different from each other by 90 degrees or the count value of the storage means due to the entry during the power failure Based on the difference in the stored value regarding the rotation angle of the means, it can be determined that there was one ball in the specific winning opening 30 during the power failure. In this embodiment, it is possible to determine up to three balls during a power outage. It is almost impossible to have four balls during a power failure. In such a case, up to seven balls can be detected by changing the number of electrode pairs from two to three.

FIG. 11 is a combination of a feather winning sensor that can accurately determine whether or not to enter a specific winning gate during a power outage, and can prevent troubles and illegal acts with the player. It is a figure which shows the power recovery process of a prize. When the power failure is restored, a reset release signal from the power failure detection unit of the power supply device is sent to the reset terminal of the CPU of the main control unit MC, and the CPU executes a power recovery process for a specific winning. The CPU executes a parity check of information stored in the backup RAM (S20), and determines whether the parity is normal (S21). If it is not normal, there is an error in the stored and stored information, so initialization is performed to delete the information (S22). If the parity is normal, the stored information is correct and the information is restored. Here, the sensor values of the left and right entrance sensors C1, C2 of the movable members F1, F2 of the blades are restored from the backup RAM (S23). If there is a ball in the ball sensors C1 and C2 before the power failure process according to the sensor values of the ball sensors C1 and C2 (YES in S24), the count of the ball sensor 30s in the specific winning opening 30 before the power failure process is counted. The value (Vo) is restored from the backup RAM (S25), and the count value (Vp) of the ball sensor 30s of the specific winning opening 30 after the power recovery process is read (S26). If the answer is NO in S24, the specific winning opening will not be entered during a power failure, and the power recovery process for the specific winning is terminated. If the count value (Vp) of the ball winning sensor 30s of the specific winning opening 30 after the power recovery process is different from the count value (Vo) of the ball winning sensor 30s of the specific winning opening 30 before the power failure process, the determination in S27 is made. It becomes YES, it is determined that the player has entered the specific winning opening 30 during a power failure, the winning ball payout flag is turned ON (S28), the jackpot game flag is turned ON (S29), and the power recovery process for the specific winning is performed. finish. When the count value (Vp) of the winning sensor 30s of the specific winning opening 30 after the power recovery process is the same as the count value (Vo) of the winning sensor 30s of the specific winning opening 30 before the power failure process, the winning space 21 It is determined that the game ball that has entered the ball has not entered the specific winning port 30, but has entered the normal winning port 31, and the power recovery process is terminated without changing the jackpot game flag. Also in this case, since the player has entered the normal winning opening 31, the winning ball payout flag may be turned ON to end the power recovery process.

In addition, when the winning sensor 31s is provided also in the normal winning path 40 connected to the normal winning opening 31, the count value of the winning sensor 31s of the normal winning opening 31 after the power recovery process and the normal winning before the power failure process are provided. If the count value of the entrance sensor 31s of the mouth 31 is different, it is determined that the player has entered the normal winning opening 31 during a power failure, and the payout flag of the prize ball is turned ON to complete the normal winning power recovery process. Can do.

In addition, the configuration of the present application is also effective against a so-called radio wave that is a fraudulent action that causes a malfunction by a powerful electromagnetic wave generator with respect to a proximity switch that detects a change in impedance of a detection coil and detects a ball. is there. In the present application, a sensor that detects a ball enters a rotating body that rotates by a predetermined angle in one direction by contact with a game ball, a shaft that transmits the rotation of the rotating body, and a rotation of the predetermined angle to the shaft. This is because, since the detection unit is configured to detect, it is indispensable that the game ball actually exists, and it is possible to prevent such an electromagnetic got that causes the entrance sensor to malfunction without the game ball.
