The CPU 601 selects and reads out the operation pattern data stored in the ROM 602 corresponding to the command sent from the effect control unit 400. Then, the CPU 601 controls the operation of the movable accessory 22 based on the read operation pattern data.

(First embodiment)
Next, with reference to FIG. 3, the movable accessory 22 and its control of the gaming machine 1 according to the first embodiment will be described. FIG. 3 is a block diagram illustrating details of the configuration of the lamp control unit 600 and the movable accessory 22 according to the first embodiment.

  As illustrated in FIG. 3, the lamp control unit 600 includes a motor driver 611 in addition to the CPU 601, the ROM 602, and the RAM 603 described above. In addition, a motor 612 is electrically connected to the lamp control unit 600. The motor 612 is, for example, a stepping motor that rotates once in 100 steps. The ROM 602 stores a control program for controlling the motor 612. The CPU 601 executes the program to rotate the motor 612 via the motor driver 611 and move the movable accessory 22.

  The motor 612 is controlled by the CPU 601 and the motor driver 611. Specifically, the CPU 601 transmits a pulse signal and information regarding the rotation direction to the motor driver 611. When the motor driver 611 receives the pulse signal and the rotation direction information from the CPU 601, the motor driver 611 rotates the motor 612 in a predetermined direction by one step (ie, 3.6 degrees). The CPU 601 can rotate the motor 612 at a predetermined speed by transmitting pulse signals at predetermined time intervals.

  The motor 612 is connected to the movable accessory 22 and gives a driving force to the movable accessory 22. The movable accessory 22 is moved by a driving force from the motor 612 and performs a predetermined operation. The movable accessory 22 is a accessory that partially rotates in accordance with the rotational force from the motor 612.

  FIG. 4 is a diagram showing details of the movable accessory 22. As shown in FIG. 4, the movable combination 22 is a combination in which the rotating body 22a rotates in a predetermined direction around the rotation shaft 22b. The rotating body 22a is initially stationary (while the effect is not executed) at a position (initial position) as shown in FIG. When the effect is executed based on the command sent from the effect control unit 400 as described above, the rotating body 22a rotates. Specifically, when the CPU 601 of the lamp control unit 600 receives a command related to the operation of the movable accessory 22 from the effect control unit 400, the CPU 601 drives (rotates) the motor 612 with a control pattern corresponding to the command. Then, the driving force from the motor 612 is transmitted to the rotating shaft 22b via a gear or the like (not shown), and the rotating body 22a rotates. The ROM 602 stores a plurality of control patterns corresponding to commands from the effect control unit 400 in advance. Production of different operation patterns is executed by such a plurality of control patterns. The effects of different operation patterns are effects in which the rotation direction, rotation time, speed, and the like of the rotating body 22a are different. In this way, the effect is executed when the rotating body 22a performs a predetermined operation in response to the command from the effect control unit 400. When the effect is finished, the rotating body 22a is controlled to stop at the initial position.

  On the other hand, as shown in FIGS. 3 and 4, a photosensor 613 is provided in the vicinity of the movable accessory 22. The photo sensor 613 irradiates light to a part of the movable accessory 22 (initial position of the rotating body 22a), thereby determining whether or not the rotating body 22a has passed the position (the rotating body 22a is at that position). Whether or not it exists) (see FIG. 4). When the photo sensor 613 detects the rotating body 22a, the photo sensor 613 transmits information indicating the detection to the CPU 601. Thereby, the CPU 601 can determine whether or not the rotating body 22a exists at the initial position and how many times the rotating body 22a has rotated.

  Next, details of the control of the movable accessory 22 will be described. As described above, the ROM 602 stores a control pattern of the motor 612 in advance, and the rotating body 22a operates according to the control pattern. For example, in an operation pattern in which the rotator 22a rotates in a predetermined direction for 10 seconds, the rotator 22a is accelerated for a predetermined time (for example, 1 second) after the start of production, and then moves at a constant speed at a predetermined speed. It is controlled to rotate at a constant speed. Then, when a predetermined time (for example, 9 seconds) elapses from the start of the production (or when the rotation is performed a predetermined number of times), the rotating body 22a is decelerated for the remaining time (1 second) and stops at the initial position. That is, when the effect is finished, the rotating body 22a is controlled to stop at the initial position by being controlled by the control pattern. Here, since the rotation angle of the motor 612 is controlled by the pulse signal from the CPU 601 as described above, the rotation speed of the motor 612 is determined by the number of pulse signals (pulse frequency) from the CPU 601 per unit time. . Accordingly, when the rotating body 22a is decelerated from the state of constant velocity motion, the CPU 601 decelerates the rotating body 22a by gradually decreasing the pulse frequency during the remaining time (1 second). Then, the CPU 601 changes the pulse frequency in a predetermined pattern so that the rotating body 22a stops at the initial position.

  FIG. 5 is a diagram showing an example of the relationship between the pulse frequency of the pulse signal input to the motor 612 and time when the rotating body 22a is rotated in a certain pattern. In FIG. 5, the vertical axis represents the pulse frequency, and the horizontal axis represents the elapsed time from the start of production (the rotation start of the rotating body 22a). As described above, the rotational speed of the motor 612 is proportional to the pulse frequency. As shown in FIG. 5, the motor 612 is accelerated at a predetermined rate (acceleration pattern) for 0 to 1 second (acceleration period), and the motor 612 is equal for 1 to 9 seconds (constant speed period). Move fast (constant velocity pattern). During 9 to 10 seconds (deceleration period), the motor 612 is decelerated at a predetermined rate (deceleration pattern). In FIG. 5, the graph is linear during the acceleration period or deceleration period, that is, the rotational acceleration (angular acceleration) of the motor 612 is constant, but is actually stepped. The graph in the acceleration period or the deceleration period may be curved. The rotational acceleration of the motor 612 is a rate of change per unit time of the rotational speed of the motor, and means rotational acceleration and deceleration.

  When the motor 612 is operated in a pattern as shown in FIG. 5, the rotating body 22a, for example, rotates 18 times from the initial position and stops at the initial position again. Here, the area surrounded by the horizontal axis and the graph in FIG. 5 (that is, the integral value obtained by integrating the rotational speed of the motor 612 with time) is the number of pulse transmissions to the motor 612 (the number of steps given to the motor 612). . Accordingly, during the acceleration period, the rotating body 22a rotates once, and during the constant speed period, the rotating body 22a rotates 16 times. Further, during the deceleration period, the rotating body 22a rotates once and stops at the initial position.

  However, when a step-out occurs in the motor 612, the rotating body 22a may stop at a position delayed from the initial position. Here, the step out means a state in which the rotating shaft of the motor 612 does not rotate despite the input of a pulse signal. The step-out occurs because a large load is applied to the motor 612 or the torque of the motor 612 is insufficient.

  FIG. 6 is a diagram illustrating a case where the rotating body 22a does not stop at the initial position due to the step-out of the motor 612. FIG. 6A is a diagram illustrating the position of the rotating body 22a when the motor 612 starts decelerating when the motor 612 has stepped out. FIG. 6B is a diagram illustrating a position where the rotating body 22a has stopped when the motor 612 has stepped out. FIG. 6A is a diagram when 9 seconds have passed since the rotation start time of the rotating body 22a. If no step-out has occurred, the rotating body 22a exists at the initial position. However, since the step-out has occurred, the rotating body 22a is delayed by a predetermined step as shown in FIG. In this state, when deceleration is started with the deceleration pattern, the rotating body 22a stops with a predetermined step delay as shown in FIG. 6B. When step-out occurs in this way, the rotating body 22a does not stop at the initial position, which is not preferable in appearance. In addition, when the movable accessory 22 appears only at the time of production and is accommodated at times other than the performance, it may not be accommodated unless the rotating body 22a is stopped at the initial position. That is, when the movable accessory 22 is accommodated, the movable accessory 22 may not be accommodated because there is a case where the rotating body 22a is not stationary at the initial position and may come into contact with a nearby accessory.

  Therefore, in the gaming machine 1 according to the first embodiment, the step-out is detected, and the speed of the rotating body 22a is controlled according to the degree. FIG. 7 is a chart showing the relationship between the degree of step-out and the deceleration pattern. As shown in FIG. 7, for example, when the step out is between 1 to 5 steps, the rotating body 22a is decelerated by the deceleration pattern A (A represents the acceleration of rotation (angular acceleration)), and the step out is from 6 to 6. In the case of 10 steps, the rotating body 22a is decelerated by the deceleration pattern B. In the deceleration pattern B, the rotating body 22a is decelerated more slowly than the deceleration pattern A.

  Here, the degree of step-out is detected based on the pulse signal from the CPU 601 to the motor driver 611 and the detection result of the photosensor 613. Specifically, when transmitting a pulse signal to the motor driver 611, the CPU 601 counts the number of transmitted pulses. For example, in the case of a motor that rotates once in 100 steps, the CPU 601 can determine how many times the motor 612 has been rotated by counting the number of transmitted pulses. On the other hand, when the rotating body 22a passes through the initial position, the photosensor 613 transmits a signal indicating that the rotating body 22a has been detected to the CPU 601. Therefore, the CPU 601 can know how many times the motor 612 has actually rotated by counting the signals from the photosensor 613. The CPU 601 can detect how many steps the motor 612 is out of step based on the number of pulse signals transmitted to the motor driver 611 at the time when the signal from the photosensor 613 is received. For example, when the number of transmissions of pulse signals at the time of receiving a signal from the photosensor 613 is 102, the CPU 601 can determine that a two-step step-out has occurred.

  Next, details of each deceleration pattern shown in FIG. 7 will be described. FIG. 8 is a conceptual diagram showing each deceleration pattern. As shown in FIG. 8, in the deceleration pattern A, the step-out is relatively small as 1 to 5 steps. Therefore, the rotating body 22a decelerates at the same rotational acceleration as the normal (when no step-out occurs) deceleration pattern. Is done. In the deceleration pattern A, when the step-out has occurred, for example, in 3 steps, the rotating body 22a stops at a position delayed by 3 steps from the initial position (position shifted by 3 steps in the direction opposite to the rotation direction). When the degree of step-out is relatively small, there is no problem in appearance even if the rotating body 22a is slightly shifted from the initial position and stopped. Further, as described above, a slight shift is not a problem as long as the movable accessory 22 is not contacted with another accessory when the movable accessory 22 is accommodated. Therefore, when the degree of step-out is relatively small, the rotating body 22a is decelerated in the same pattern as usual.

  However, when the degree of step-out is relatively large, the rotating body 22a stops with a relatively large shift from the initial position, and thus the above-described problem may occur. Therefore, when the degree of step-out is relatively large, the rotating body 22a is decelerated relatively slowly (the deceleration of the rotating body 22a (acceleration in the direction opposite to the rotation direction) is reduced) and the vicinity of the initial position. To stop. Specifically, as shown in FIG. 8, in the deceleration pattern B, the rotating body 22a is decelerated more slowly than the deceleration pattern A. That is, in the deceleration pattern B, the step-out occurs in 6 to 10 steps, so that the rotation speed of the rotating body 22a is controlled so that the deceleration period becomes longer than that in the case of the deceleration pattern A. As described above, since the area surrounded by the graph of FIG. 8 and the horizontal axis is the number of pulse transmissions to the motor 612, the number of pulse transmissions to the motor 612 from when the rotating body 22a starts decelerating is reduced. There are more deceleration patterns B than patterns A. That is, the deceleration pattern B advances in a predetermined step rotation direction than the deceleration pattern A (the angle at which the rotating body 22a rotates during the deceleration period is greater in the deceleration pattern B than in the deceleration pattern A). Therefore, the rotating body 22a is delayed by 6 to 10 steps from the initial position at the time of starting deceleration, but the rotating body 22a stops near the initial position because the delay is eliminated at the time of stopping. Become. Similarly, when the step-out occurs in 11 to 15 steps, the rotating body 22a is further slowly decelerated by the deceleration pattern C. Thereby, even if it is a case where the degree of step-out is large, the rotary body 22a can be stopped in the vicinity of an initial position.

  Next, the control of the movable accessory 22 performed by the lamp control unit 600 will be described in detail with reference to FIG. FIG. 9 is a flowchart illustrating an example of processing performed by the lamp control unit 600. When a command indicating execution of an effect using the movable accessory 22 is sent from the effect control unit 400, the CPU 601 copies the program stored in the ROM 602 to the RAM 603 and starts executing the program. The flowchart shown in FIG. 9 is a flowchart showing a process performed after the above process is completed.

  First, in step S1, the CPU 601 accelerates the motor 612 in a predetermined pattern. The processing here is processing in the acceleration pattern in FIG. The acceleration pattern is a pattern related to the control of the motor 612 stored in the RAM 603 in advance. Specifically, the CPU 601 transmits to the motor driver 611 a pulse signal and information indicating the rotation direction in a predetermined pattern (time interval of a pattern in which the motor 612 accelerates). For example, the CPU 601 transmits a pulse at a relatively low frequency to the motor driver 611 during a predetermined period (or predetermined step) from the start of acceleration. The CPU 601 transmits pulses at a higher frequency in the next predetermined period than in the first predetermined period. In this manner, the CPU 601 accelerates the motor 612 by gradually increasing the pulse frequency in accordance with the passage of time (or the cumulative number of steps) from the start of acceleration. Note that the CPU 601 counts the number of transmitted pulse signals and stores it in the RAM 603 as a count value i. Next, the CPU 601 executes the process of step S2.

  In step S2, the CPU 601 performs motor control for production. The process here is a process with a constant velocity pattern in FIG. The constant velocity pattern is a pattern related to the control of the motor 612 stored in the RAM 603 in advance. Specifically, the CPU 601 transmits a pulse signal and information indicating the rotation direction at regular time intervals to the motor driver 611 so that the motor 612 rotates at a constant speed. Similarly to step S1, the CPU 601 counts the number of transmitted pulse signals, and stores the number of transmitted pulses in the RAM 603 in addition to the count value i. In the process of step S2, the CPU 601 may not only rotate the motor 612 at a constant speed, but also rotate it in various patterns according to the contents of the effect. For example, the motor 612 may be controlled such that the rotation direction changes at a predetermined time interval. Next, the CPU 601 executes the process of step S3.

  In step S3, the CPU 601 determines whether the photo sensor 613 has detected the rotating body 22a. Note that the CPU 601 stores the number of times that the photo sensor 613 has detected the rotating body 22a in the RAM 603 as a detection number value m. That is, in step S <b> 3, the CPU 601 adds 1 to the number of detections m stored in the RAM 603 and stores it in the RAM 603 again. Accordingly, the detection frequency value m represents the number of times the rotating body 22a has actually rotated since the rotating body 22a started rotating. When the photo sensor 613 detects the rotating body 22a, the CPU 601 next executes the process of step S4. On the other hand, when the photo sensor 613 has not detected the rotating body 22a, the CPU 601 next executes the process of step S6.

  In step S4, the CPU 601 acquires the number of steps. Specifically, the CPU 601 refers to the count value i stored in the RAM 603 and stores it in the RAM 603 as the step number n. That is, the CPU 601 stores the total number of pulses transmitted to the motor 612 in the processes of steps S1 and S2 in the RAM 603 as the step number n. Next, the CPU 601 executes the process of step S5.

  In step S5, the CPU 601 detects the degree of step-out. Specifically, the CPU 601 subtracts a value obtained by multiplying the number of steps m acquired in step S4 by the number of steps m of the motor 612 (= step number n−detection). The number of times m × 100) is calculated. When no step-out occurs in the motor 612, the rotation given to the motor 612 matches the actual rotation, so the degree of step-out becomes zero. However, when step-out has occurred in the motor 612, the degree of step-out becomes a non-zero value. For example, when the number of steps n is 302 and the number of detections m (the actual number of rotations of the rotating body 22a) is 3, the degree of step-out is 2 steps. When some force is applied in the rotation direction of the rotating body 22a, the degree of step-out may be a negative value (the number of steps actually rotated is larger than the number of steps given to the motor 612). Sometimes). Next, the CPU 601 executes the process of step S6.

  In step S6, the CPU 601 determines whether to start deceleration. Here, it is determined whether or not to end the effect of the movable accessory 22. The CPU 601 determines whether or not to end the effect based on the elapsed time from the start of the effect and the command from the effect control unit 400. If the determination result is affirmative, the CPU 601 executes the process of step S7. If the determination result is negative, the CPU 601 returns the process to step S2 and continues to perform motor control.

  In step S7, the CPU 601 sets a deceleration pattern. Specifically, the CPU 601 refers to the table stored in the RAM 603 (the table showing the relationship between the degree of step-out and the deceleration pattern shown in FIG. 7), according to the degree of step-out detected in step S5. Set the deceleration pattern. Next, the CPU 601 executes the process of step S8.

  In step S8, the CPU 601 controls the motor with the deceleration pattern set in step S7. The process here is a process in the deceleration pattern in FIG. 5 or 8 and is a process for stopping the movable accessory 22. Specifically, the CPU 601 transmits to the motor driver 611 a pulse signal and information indicating the rotation direction in a predetermined pattern (time interval of a pattern in which the motor 612 decelerates at a predetermined acceleration (deceleration)). The CPU 601 decelerates the motor 612 until the rotation speed of the motor 612 becomes zero. And the movable accessory 22 stops and the process of this flowchart is complete | finished (production | presentation is complete | finished).

  As described above, by detecting the step-out of the motor 612 and controlling the deceleration of the motor 612 in accordance with the degree, the movable accessory 22 (the rotating body 22a) can be stopped at a desired position. Further, since the speed until the rotating body 22a stops changes according to the degree of step-out, it can be determined at a glance whether or not step-out has occurred. Further, by storing the degree of step-out and the deceleration pattern in a table in advance as shown in FIG. 7, the movable accessory 22 can be controlled without imposing a large load on the CPU 601.

  In addition, although the said embodiment demonstrated the rotating accessory as an example, in other embodiment, the accessory which operate | moves in one direction may be sufficient. For example, the rotational speed (angular speed) of the motor may be controlled in order to stop the accessory that moves in the left-right direction at a predetermined position. Further, the present invention is not limited to these examples, and the present invention can be applied to the control of an arbitrary accessory driven by a motor.

  Moreover, in the said embodiment, in order to stop an accessory in a predetermined position, the deceleration of the motor was controlled according to the step-out degree of the motor. In another embodiment, the speed of the motor is controlled not only in the deceleration period for stopping the accessory at a predetermined position, but also in the acceleration period or the constant speed period according to the degree of step-out of the motor. Also good. For example, when the motor is accelerated, a step-out may occur during the acceleration period depending on the magnitude of the rotational acceleration (angular acceleration). When a step-out occurring in such an acceleration period is detected, control may be performed to reduce the rotational acceleration of the motor. Thereby, it is possible to prevent the step-out that occurs because the rotational acceleration is too large. Similarly, when the motor is rotating at a constant speed, by controlling the motor speed by the above-described method, the step-out can be prevented even when the step-out is likely to occur above a certain speed. Can do. In addition to the purpose of stopping the accessory at a predetermined position, the speed of the motor during the deceleration period may be controlled according to the degree of step-out for various purposes. In this way, the rotational speed of the motor may be controlled in accordance with the difference between the drive amount (rotation speed or rotation angle) given to the motor and the amount actually driven by the accessory.

  In the above embodiment, the accessory is moved using the stepping motor. However, in other embodiments, other motors such as a DC motor and a servo motor may be used.

  In the above embodiment, it is detected whether or not a part of the movable accessory exists at the initial position using one photosensor. However, the position of the movable accessory is accurately detected using a plurality of photosensors. May be. In other embodiments, not only the photosensor but also any sensor may be used for detecting the position of the movable accessory.

  In the above embodiment, the degree of step-out is detected based on the difference between the rotational speed given to the motor and the actual rotational speed of the accessory. In another embodiment, the step-out detection method is not limited to this, and the step-out may be detected by any method.

  Further, the cause of the difference between the rotational speed given to the motor and the actual rotational speed of the accessory is not limited to the motor step-out. For example, when the driving force of the motor is transmitted to the movable accessory due to idle rotation of a gear or the like, the transmission of the driving force may not be normally performed. Can be stopped in position.

  In the above embodiment, the rotating body 22a is stopped at a predetermined position by decreasing the motor deceleration as the degree of motor step-out increases. In another embodiment, when the motor is decelerated at a constant deceleration and the motor is stopped, the rotating body 22a may be stopped at a predetermined position by rotating the motor by the number of detected step-out steps. Good.

  In the above embodiment, the deceleration pattern corresponding to the degree of motor step-out is stored in the table. However, in other embodiments, the rotation speed of the motor is obtained by calculation according to the degree of motor step-out. May be.

(Second Embodiment)
Next, a second embodiment will be described. Here, the details of the inspection method in the case of reusing (reusing) the movable accessory 22 and the motor 612 described above will be described. Also in the second embodiment, the configurations of the lamp control unit 600 and the movable accessory 22 are the same as those in the first embodiment, and thus the description thereof is omitted.

  As described above, the motor 612 may be stepped out for various reasons, and the movable accessory 22 may not operate normally. Further, the driving force of the motor 612 may not be normally transmitted to the rotating body 22a due to secular change or manufacturing error of the movable accessory 22 and a gear that transmits the driving force of the motor 612 to the movable accessory 22. Thus, if there is a malfunction in the movable accessory 22, the movable accessory 22 cannot be taken out of the gaming machine collected from the market and reused for a new gaming machine.

  Therefore, it is necessary to visually inspect whether or not such a movable accessory 22 operates normally by actually moving the movable accessory 22.

  However, it is difficult to detect whether or not the movable accessory 22 operates normally visually. For example, as shown in FIG. 6, the rotating body 22 a is stopped by deviating from the initial position by a predetermined step, but it is difficult to visually determine how much it is deviated or actually deviated. It is.

  Therefore, in the second embodiment, an inspection command is transmitted from the effect control unit 400 to the lamp control unit 600 to operate the movable accessory 22. Specifically, when the main control unit 100 is replaced with a main control unit for inspection and power is turned on or a predetermined operation is performed, a predetermined command is transmitted from the main control unit for inspection to the effect control unit 400. . In response, an inspection command is transmitted from the effect control unit 400 to the lamp control unit 600. When the inspection command is received, the CPU 601 starts a predetermined operation for inspection. This operation is the same as the actual performance operation, but when an unacceptable step-out is detected, the operation is different from the actual performance operation. That is, when an unacceptable step-out is detected when the movable accessory 22 operates and decelerates, the CPU 601 seems to decelerate the rotation body 22a more slowly (decrease the deceleration) than when there is no step-out. To control. FIG. 10 is a chart showing the relationship between the degree of step-out and the deceleration pattern in the second embodiment. As shown in FIG. 10, for example, when the degree of step-out is between 1 to 5 steps, the rotating body 22a is decelerated with the deceleration pattern A, and when the step-out is 6 steps or more, the rotating body 22a with the deceleration pattern D is used. Decelerate. In the deceleration pattern D, for example, the rotating body 22a is decelerated more slowly than the deceleration pattern C (see FIG. 8) (the deceleration is further reduced).

  As a result, whether or not a difference between the rotational speed given to the motor 612 and the actual rotational speed of the rotating body 22a is greater than or equal to a predetermined value due to step-out or other causes is determined. It can be easily confirmed by observing the movement of time. Further, it is preferable to confirm whether or not the movable combination 22 can be reused by operating the movable combination 22 in the same manner as the actual production operation. On the other hand, it is difficult to confirm whether or not it is normal in the process of actual performance operation. That is, when the movable accessory 22 itself operates, but there is a problem that the step-out frequently occurs, it is difficult to determine such a problem in the process of operation. However, in the method described above, the effect operation is actually started and the effect is executed. Then, it is detected whether or not a step-out has occurred when finishing the effect operation, and when the step-out has occurred, the rotating body 22a is slowly decelerated. Thereby, with the method mentioned above, the operation | movement of the movable accessory 22 can be confirmed easily and reliably.

  As described above, in the second embodiment, it can be easily determined whether or not the movable accessory 22 can operate normally. Further, by preparing an operation pattern of the movable accessory 22 corresponding to the inspection command in advance, the determination becomes easy.

  Note that it may be determined whether or not the movable accessory 22 can be reused by measuring the operating speed of the movable accessory 22 with a speedometer or the like instead of visually.

  Further, the inspection method according to the second embodiment is not limited to the reuse of the movable accessory 22 but is also effective as an inspection method at the manufacturing stage.

  In the above description, the inspection command is transmitted to the lamp control unit 600 by exchanging it with the main control unit for inspection. However, the command can be reused by transmitting a normal effect command and operating the movable accessory 22. It may be determined whether or not. That is, the movable accessory 22 can be inspected by visually confirming the effect of the movable accessory 22 that is performed in response to a command from the normal main control unit 100.
