Description

  The present invention relates to a gaming machine, and more particularly to a technique for driving and controlling an electric motor that operates a movable member.

  2. Description of the Related Art Conventionally, in a pachinko gaming machine, an electric motor that activates a movable member (game accessory member) for game effects is driven and controlled by a motor control device (a computer on a lamp control board) via a motor driver. Specifically, the motor control device transmits a plurality of motor control data for causing the movable member to execute a series of operations to the motor driver, and the motor driver drives the electric motor based on the plurality of motor control data.

  By the way, when the processing speed (for example, 500 μs / step) of the motor control device (CPU) is relatively fast, the motor control device sequentially transmits the plurality of motor control data to a motor driver in a plurality of steps. Fine control of the motor becomes possible. On the other hand, when the processing speed of the motor control device (for example, 20 ms / step) is relatively slow, the motor control device transmits the plurality of motor control data to the motor driver in a batch and stores the plurality of motor control data. It is preferable that the electric motor is driven based on the motor control data.

  Here, Patent Document 1 discloses a stop processing technique in which the movable member is reciprocally rotated in the direction parallel to the board surface of the game board over the standby position and the protruding position, and the movable member is stopped at the standby position. Yes. In this stop processing technique, in the computer of the lamp control board, first, 0 is initially set as the driving number n, and finally, the calculated driving number n becomes a set number N (for example, N = 30). In some cases, the electric motor is stopped.

  Therefore, when a stop command is received from the effect board after the drive number n is initially set to 0, N is set to n, and then the standby position of the movable member is detected by the sensor. Immediately, it is determined whether n = N, and since an affirmative determination is made there, the electric motor is stopped. On the other hand, when the stop command is not received and the standby position of the movable member is detected by the sensor, n is added to n + 1. Thereafter, it is determined whether or not n = N. If n ≠ N, the process returns to the step of determining whether or not a stop command has been received. Thereafter, if n = N even if no stop command is received, The electric motor is stopped.

  In a pachinko machine, the motor control device transmits a plurality of motor control data for causing the movable member to execute a series of operations to the motor driver in a batch, stores the motor control data, and performs electric operation based on the plurality of motor control data stored by the motor driver. In a motor configured to drive a motor, a motor control device having a relatively slow processing speed is adopted to reduce the control load, and particularly fine control of the movable member (and other production equipment) is required. It is suitable for those that do not.

  However, since the motor control device cannot obtain feedback that can know the state (position) of the movable member from the motor driver after transmitting a plurality of motor control data, and even if the feedback is obtained, Since it is not reflected in the control of the electric motor, if the motor control data transmitted / stored in the motor driver has a problem (for example, the motor control data changes due to noise, etc.), the electric motor is not driven normally. May not operate normally.

  If a problem occurs in the motor control data transmitted / stored to the motor driver, for example, there is a concern that the electric motor will not stop (excited all the time), which may cause the electric motor to overheat and fail. In addition, for example, there is a concern that the movable member does not stop operating at a predetermined fixed position, that is, after the movable member stops operating, the position detection sensor does not detect that the movable member is in the fixed position. It looks bad and causes the movable member to be damaged by mutual interference with other movable members. In this case, there is a concern that the position detection sensor is defective.

Then, control information (payout information) is output to the game control board 32. The computer of the effect control board 33 receives the control information from the game control board 31, the image control board 34, and the lamp control board 35 and the signal from the effect button SW6 and controls the image control board 34 and the lamp control board 35. Output information.

  The computer of the image control board 34 receives the control information from the effect control board 33, controls the game display image display 16 and the speaker 37, and outputs the control information to the effect control board 33. The computer of the lamp control board 35 receives the control information from the effect control board 33 and is synchronized with the control of the image control board 34 mainly by the computer, so that the game effect frame lamp 38a, the board lamp 38b, and the movable accessory. The device 17 is controlled.

  As shown in FIG. 6, the computer of the lamp control board 35 constitutes a motor control means 40 for driving and controlling the electric motor 25 of the movable accessory device 17 via a motor driver 45 which is a motor driving circuit. The means 40 includes effect motor control means 41, stop processing means 42, return motor control means 43, and return stop processing means 44 (fixed position movement stop processing means 44). The motor driver 45 includes a microprocessor, and a register 46 for storing motor control data is provided therein. Here, the motor control means 40 (that is, the computer of the lamp control board 35) has a relatively slow processing speed (for example, 20 ms / step) of the CPU.

  When the production motor control means 41 receives an execution command (command) of a specific game production from the production control board 33, the movable members 21, 22 move from the standby position to the operation position based on the execution command, and again. A plurality of motor control data for causing the movable members 21 and 22 to execute a series of operations of moving from the operating position to the standby position are collectively transmitted to the motor driver 45 and stored in the register 46, and the motor driver 45 stores the register 46 in the register 46. The electric motor 25 is driven on the basis of a plurality of motor control data stored in. Each motor control data includes information such as the driving direction, driving amount, and driving speed of the electric motor 25.

  The stop processing means 42 measures the elapsed time t1 after the effect motor control means 41 transmits the plurality of motor control data, and the elapsed time t1 is set to a set time T1 set in association with the plurality of motor control data. In this case, a plurality of stop signals are transmitted to the motor driver 45 at intervals of minute time ΔT1, and when the motor driver 45 is driving the electric motor 25 when receiving the stop signal, the motor driver 45 Stop driving. In the stop processing means 42, at least the operation time T1 required for the series of operations of the movable members 21 and 22 is set as the set time T1. The stop processing means 42 receives a signal from the position detection sensor 29 after transmitting a plurality of stop signals, and determines whether or not the movable members 21 and 22 are in a fixed position (standby position).

  For example, as shown in the time chart of FIG. 7, the stop processing means 42 has elapsed time from the start of driving at the time of transmission of a plurality of motor control data (at the start of transmission or at the end of transmission), that is, at the time of production of the electric motor 25. When t1 is started, a stop signal is transmitted when an operation time T1 required for a series of operations of the movable members 21 and 22 has passed (from t1 = T1), and when the first stop signal is transmitted. Then, the remaining 2 stop signals (total 3 stop signals) are transmitted at intervals of 20 ms (= ΔT1), for example. Then, it is determined whether or not the movable members 21 and 22 are in a fixed position when a minute time has elapsed since the last stop signal was transmitted (or when the last stop signal was transmitted).

  Next, after the stop processing means 42 transmits a plurality of stop signals, when it is determined that the movable members 21 and 22 are not in the fixed positions, the return motor control means 43 returns the movable members 21 and 22 to the fixed positions ( Return motor control data (fixed position movement motor control data) to be moved) is transmitted to the motor driver 45 and stored in the register 46, and the electric motor is based on the return motor control data stored in the register 46 by the motor driver 45. 25 is driven. The register 46 newly stores return motor control data after erasing a plurality of motor control data. Note that the return motor control data includes information such as the driving direction, driving amount, and driving speed of the electric motor 25, so that the position of the movable member 21, 22 is fixed regardless of the position of the movable region. It is data that can move reliably.

  The return stop processing means 44 measures the return elapsed time t2 (fixed position movement elapsed time t2) after the return motor control means 43 transmits the return motor control data, and the return elapsed time t2 corresponds to the return motor control data. In addition, when the return setting time T2 (fixed position movement setting time T2) is set, a plurality of return stop signals (fixed position movement stop signals) are transmitted to the motor driver 45 at minute time intervals ΔT2, and the motor driver If the electric motor 25 is being driven when the return stop signal is received, 45 stops the driving of the electric motor 25. In the return stop processing unit 44, at least a return operation time T2 required for the return operation of the movable members 21 and 22 is set as the set time T2. The return stop processing means 44 receives a signal from the position detection sensor 29 after transmitting a plurality of return stop signals, and determines whether or not the movable members 21 and 22 are in a fixed position (standby position).

  For example, as shown in the time chart of FIG. 8, the return stop processing unit 44 returns from the start of driving when the return motor control data is transmitted (at the start of transmission or at the end of transmission), that is, at the return of the electric motor 25. The elapsed time t2 is started, and when the return operation time T2 required for the return operation of the movable members 21 and 22 has passed (from t2 = T2), a return stop signal is transmitted and the first return stop is performed. From the time of signal transmission, the remaining two return stop signals (total three return stop signals) are transmitted at intervals of, for example, 20 ms (= ΔT2). Then, it is determined whether or not the movable members 21 and 22 are in a fixed position when a minute time elapses from the time when the last return stop signal is transmitted (or when the last return stop signal is transmitted).

  Next, when the return stop processing means 44 transmits a plurality of return stop signals and receives a signal from the position detection sensor 29 and determines that the movable members 21 and 22 are not in a fixed position, the motor control means 40 (effect motor) The control means 41 and the return motor control means 43) do not drive the electric motor 25, that is, prohibit the subsequent operation of the movable members 21 and 22 (drive of the electric motor 25).

  Next, motor control including the above-described control and processing executed by the motor control means 40 will be described based on the flowcharts of FIGS. This motor control is started every 20 ms. As shown in FIG. 9, first, it is determined whether or not the operation prohibition flag F = 1 (S1). If the determination of S1 is Yes, the process returns. The operation prohibition flag F is stored and held even when the power is cut off. However, the operation prohibition flag F may be initialized to 0 when the power is turned on.

  If the determination in S1 is No, it is determined whether or not an execution command (command) for a specific game effect (that is, a game effect that operates the movable accessory device 17) is received from the effect control board 33 (S2), and S2 If the determination is No, return. If the determination in S2 is Yes, a plurality of motor control data for causing the movable members 21 and 22 to execute a series of operations according to the received execution command are transmitted to the motor driver 45 (S3) and stored in the register 46 Subsequently, the elapsed time t1 starts to be timed (S4). Next, it is determined whether or not t1 ≧ set time (operation time) T1 (S5). If the determination in S5 is No, the process waits until the determination in S5 becomes Yes.

  Thereafter, when the S5 determination becomes Yes, a stop signal is transmitted to the motor driver 45 (S6), and then the stop signal transmission count n1 is incremented to n1 + 1 (S7). Next, it is determined whether or not n1 = N1 (for example, N1 = 3) (S8). If the determination in S8 is No, a minute time ΔT1 (for example, from the previous execution of S6 (when the stop signal is transmitted)) It is determined whether or not (ΔT1 = 20 ms) has elapsed (S9). If the determination in S9 is Yes, the process returns to S6, and a stop signal is transmitted to the motor driver 45 again (S6).

  The processing including S6 is repeatedly executed until the determination in S8 becomes Yes, and eventually, a plurality (N1 = 3) of stop signals are transmitted to the motor driver 45 at intervals of a minute time ΔT1. If the determination in S8 is Yes, the elapsed time t1 and the stop signal transmission count n1 are reset to 0 (S10), and then it is determined whether or not the movable members 21 and 22 are in a fixed position (standby position) (S11). ). If the determination in S11 is Yes, the process returns. If the determination in S11 is No, the process proceeds to S12.

  As shown in FIG. 10, when the determination in S11 is No, the return motor control data is transmitted to the motor driver 45 (S12) and stored in the register 46, and then the return elapsed time t2 is started (S13). ). Next, it is determined whether or not t2 ≧ reset setting time (return operation time) T2 (S14). If the determination in S14 is No, the process waits until the determination in S14 becomes Yes.

  Thereafter, when the determination of S14 becomes Yes, a return stop signal is transmitted to the motor driver 45 (S15), and then the return stop signal transmission count n2 is incremented to n2 + 1 (S16). Next, it is determined whether or not n2 = N2 (for example, N2 = 3) (S17). If the determination in S17 is No, a minute time ΔT2 (for example, from the previous execution of S15 (when the return stop signal is transmitted)) , ΔT2 = 20 ms) has elapsed (S18). If the determination in S18 is Yes, the process returns to S15, and a return stop signal is transmitted to the motor driver 45 again (S15).

  Until the determination in S17 becomes Yes, the processing including S15 is repeatedly executed. Eventually, a plurality (N2 = 3) of return stop signals are transmitted to the motor driver 45 at intervals of a minute time ΔT2. When the determination in S17 is Yes, the return elapsed time t2 and the return stop signal transmission count n2 are each reset to 0 (S19), and then it is determined whether or not the movable members 21 and 22 are in a fixed position (standby position). (S20). If the determination in S20 is Yes, the process returns. If the determination in S20 is No, the operation prohibition flag F is set to 1 (S21), and the process returns.

The pachinko gaming machine 1 (motor control means 40) described above has the following effects.
First, a plurality of motor control data for causing the production motor control means 41 to cause the movable members 21 and 22 to execute a series of operations are transmitted to the motor driver 45 and stored in the register 46. The motor driver 45 stores in the register 46. Since the electric motor 25 is driven based on the plurality of motor control data, the motor control means 40 (CPU of the lamp control board 35) having a relatively low processing speed (for example, 20 ms / step) is provided. Adopting it reduces the control load, and is particularly suitable for those that do not require much detailed control of the movable members 21 and 22 (and other effect devices such as other frame lamps 38a and panel lamps 38b).

  Here, since the motor control means 40 cannot obtain feedback that can know the state (position) of the movable members 21 and 22 from the motor driver 45 after transmitting a plurality of motor control data, it can also obtain the feedback. However, since it is not reflected in the subsequent control of the electric motor 25, conventionally, a problem occurs in the motor control data transmitted to the motor driver 45 and stored in the register 46 (for example, the motor control data changes due to noise or the like). In this case, there is a possibility that the electric motor 25 is not normally driven, that is, the movable members 21 and 22 are not normally operated. For example, the electric motor 25 may not stop (excited all the time), or the movable members 21 and 22 may not stop operating at a fixed position.

  Therefore, in the present invention, the stop processing means 42 counts the elapsed time t1 after the effect motor control means 41 transmits the plurality of motor control data, and the elapsed time t1 is set in association with the plurality of motor control data. When the set time T1 is reached, a plurality of stop signals are transmitted to the motor driver 45 at minute time intervals ΔT1, and the motor driver 45 is driving the electric motor 25 when receiving the stop signal. Then, the drive of the electric motor 25 is stopped.

  In the stop processing means 42, since the operation time T1 required for a series of operations of the movable members 21 and 22 is set as the set time T1, the operation ends when the movable members 21 and 22 perform a normal rendering operation. By transmitting a stop signal to the motor driver 45 at the same time, if the electric motor 25 that was originally stopped is driven due to a defect in the motor control data at the same time, the electric motor 25 is forced The drive can be stopped automatically.

  In addition, since the stop processing means 42 transmits a plurality of stop signals to the motor driver 45 at minute time intervals ΔT1, the drive stop of the electric motor 25 is forcibly stopped more reliably than when the stop signal is transmitted only once. Can be made. That is, when the originally stopped electric motor 25 is driven, if the cause is a failure of the motor control data, there is a high possibility that the same failure also occurs for the stop signal. Therefore, by transmitting a plurality of stop signals, at least one of the plurality of stop signals should be normally supplied to the motor driver 45 without causing a problem, and thus the above-described effect is reliably realized. .

  The stop processing means 42 receives the signal from the position detection sensor 29 after transmitting a plurality of stop signals, and determines that the movable members 21 and 22 are not in a fixed position, the return motor control means 43 is movable. The return motor control data for returning the members 21 and 22 to the fixed positions is transmitted to the motor driver 45 and stored in the register 46, and the electric motor 25 is changed based on the return motor control data stored in the register 46 by the motor driver 45. Since it is configured to drive, when the movable members 21 and 22 do not stop operating at a fixed position due to a problem of motor control data, the movable members 21 and 22 can be returned to the fixed position.

  In this case, the return stop processing means 44 measures the return elapsed time t2 after transmitting the return motor control data, and the return elapsed time t2 is set in association with the plurality of return motor control data. When the motor driver 45 is driving the electric motor 25 when receiving the return stop signal, the motor driver 45 transmits a plurality of return stop signals to the motor driver 45 at a minute time ΔT2 interval. The drive of the motor 25 is stopped.

  In the return stop processing means 44, the return operation time T2 required for the return operation of the movable members 21 and 22 is set as the set time T2, so that the operation ends when the movable members 21 and 22 return normally. By transmitting a return stop signal to the motor driver 45 at the same time, if the electric motor 25 that was originally stopped is driven due to a malfunction in the motor control data at the same time, the electric motor 25 Can be forcibly stopped.

  In addition, since the return stop processing means 44 transmits a plurality of return stop signals to the motor driver 45 at intervals of a minute time ΔT2, similarly to the effect when the plurality of stop signals are transmitted at intervals of a minute time ΔT1, the return stop processing is performed. Compared to the case where the signal is transmitted only once, the electric motor 25 can be forcibly stopped. When the return stop processing means 44 transmits a plurality of return stop signals and receives a signal from the position detection sensor 29 means and determines that the movable members 21 and 22 are not in a fixed position, the motor control means 40 By not driving the motor 25, it is assumed that there is a problem with the position detection sensor 29, and the operation of the movable members 21 and 22 can be prohibited to cope with it appropriately.

Various modifications can be added and implemented without departing from the spirit of the present invention. Further, the present invention is applicable not only to the electric motor 25 of the movable accessory device 17 disclosed in the above embodiment, but also to a technique for driving and controlling the electric motors of various movable accessory devices.
