  In an effect display device having a drum device of a conventional pachinko machine, an increase in the operation time of the stepping motor (that is, a pachinko game machine) causes a malfunction of the drum in which the rotating drum does not operate normally due to a failure of the stepping motor. There is a case. If the stepping motor has a built-in reduction gear mechanism, the result of disassembling and investigating the stepping motor that actually caused the malfunction of the drum resulted in a meshing failure between the gear members of the reduction gear mechanism (dropping of the gear member and gear shaft) Etc.), it was found that a drum operation failure occurred. It has also been found that this drum operation failure is likely to occur when the rotating drum is decelerated (when the rotation is stopped).

  When this drum operation failure occurs, after the rotation drum is started to rotate, it cannot be rotated at the selected and set drum operation and stopped at the selected and set drum stop position. In this case, the rotating drum is awkwardly rotating, looks bad, and above all, a specific symbol (such as “7”) of a plurality of rotating drums is arranged in a straight line even though it is not won in the big hit lottery. There is concern about the display being stopped, and if that happens, the player will be suspicious. In order to take such measures, it is necessary to detect a drum operation failure.

And the rotation angle from the stop position of the rotary drum (40) calculated from the motor start side control value to the origin position is determined as the drum operation failure. To do.

  After the rotation drum (40) is started to rotate, the rotation drum (40) can be rotated by the selected and set drum operation, and can be stopped at the selected and set drum stop position. When a malfunction of the drum that prevents the rotating drum (40) from operating normally due to a failure of the electric motor (41) occurs, when the origin position is detected by the origin detection means (44) by the drum malfunction detection means (70). From the start of rotation of the electric motor (41) until the origin position is detected by the origin detection means (44) until the rotation of the electric motor (41) is stopped. Based on the motor start side control value in the control means (43), the drum operation failure due to the rotational deviation between the control rotational position in the motor control means (43) of the rotary drum (40) and the actual rotational position is detected.

(6) The game effect displayed on the rotary drum 40 is displayed in a pseudo manner as a game effect dedicated to defective drum operation.

  Next, specific processing executed by the first and second drum operation failure detection units 70 and 71 of the image control board 28 will be described. In addition, processing executed by the motor control means 43 and the display control means 61 of the game control board 22, the effect control board 27, and the image control board 28 will be briefly described.

  First, in the game control board 22, various lottery determinations including a big hit lottery and its determination are performed in response to the winning of a game ball at the start winning ports 10a and 10b, and a change start command including information based on the lottery determination is issued. It is output to the effect control board 27. In the effect control board 27, based on the information of the change start command received from the game control board 22, any one game effect pattern is selected and set from a plurality of types of game effect patterns, and includes information on the game effect pattern. A change effect start command is output to the image control board 28.

  In the image control board 28, the motor control unit 43 controls the nine stepping motors 41 of the drum device 17 on the basis of the information of the change effect start command received from the effect control board 27, and the nine rotary drums 40 are moved. After the rotation is started, the rotation is performed by the drum operation of the game effect pattern selected and set, and the rotation is stopped at the drum stop position selected and set. The motor control means 43 controls each stepping motor 41 by a pulse output to the motor driver, the rotation angle of each rotary drum 40 is controlled by the number of pulses, and the rotation direction of each rotary drum 40 is controlled by the direction of the pulse. The rotational speed of each rotary drum 40 is controlled by the pulse frequency.

  Further, the display control means 61 synchronizes with the drum operations of the nine rotating drums 40 based on the information of the change effect start command received from the effect control board 27, and the image display 18 (the liquid crystal display panel 62, the liquid crystal adjustments). The optical panel 63) is controlled to cause the image display 18 to execute the display effect of the selected game effect pattern. Therefore, the effect image is displayed on the display unit 60 of the image display 18, and the display unit 60 can be selected between a drum display state in which the entire or arbitrary part of the display unit 60 can see through the rotating drum 40 and a drum shielding state in which the see-through cannot be seen through. Is switched to.

  The liquid crystal display 18 and the drum device 17 cooperate to execute a wide variety of game effects based on the game state (normal game state, probability variation game state, latent game state, etc.) in addition to the jackpot lottery and jackpot game. Is done. Eventually, the display unit 60 of the image display 18 is switched to the drum display state, and the nine rotating drums 40 are stopped from rotating. If there is a win in the big hit lottery, at least three rotating drums 40 are selected. A specific symbol (“7”) is stopped and displayed in a straight line.

  The first drum operation failure detection process executed by the first drum operation failure detection means 70 for each rotary drum 40 is shown in the flowcharts of FIGS. 14 and 15, and the second drum operation failure detection means 71 is used for each rotation drum 40. FIG. 16 and FIG. 17 show the second drum operation failure detection process to be executed. The first and second drum operation failure detection processes are executed by a ratio process every minute time in parallel with a series of controls executed by the motor control means 43. The information used for the first and second drum operation failure detection processes other than the detection of the origin position of the rotating drum 40 is based on the control information in the motor control means 43.

  As shown in FIG. 14, in the first drum operation failure detection process, after the pachinko gaming machine 1 is turned on, first, initial setting (S1) is executed, and the process waits until the stepping motor 41 starts to rotate. When the stepping motor 41 starts to rotate (S2), the motor control value Cn is updated (S3). In S3 and subsequent S10, the motor control value Cn is calculated and updated based on the number and direction of pulses output by the motor control means 43 to the motor driver.

  In S1, when the rotating drum 40 is restored, the rotating drum 40 rotates, and when the origin position detecting means 44 detects the origin position P0, the motor control value Cn is reset to 0, and then the rotating drum 40 is set. When the stepping motor 41 rotates in order to stop the rotation at the position, the motor control value Cn is calculated and updated in the same manner as S3.

  Next, it is determined whether or not the origin position P0 of the rotary drum 40 has been detected (S4). If S4; No, the process proceeds to S6, and if S4; Yes, the motor control value Cn is reset to 0 ( After that, the process proceeds to S6. Next, it is determined whether or not the stepping motor 41 has stopped rotating (S6). If S6; No, the process returns to S3, and S3 to S6 are repeatedly executed.

  When the stepping motor 41 stops rotating (S6; Yes), the latest motor control value Cn is stored as the motor stop side control value Ca (S7), and then the motor control value Cn is reset to 0 (S8). Wait until the motor 41 starts rotating. When the stepping motor 41 starts to rotate (S9; Yes), the motor control value Cn is calculated and updated (S10). Next, it is determined whether or not the origin position P0 of the rotating drum 40 is detected (S11), S11; No In this case, the process returns to S10, and S10 to S11 are repeatedly executed.

  When the origin position P0 of the rotating drum 40 is detected (S11; Yes), the latest motor control value Cn is stored as the motor start side control value Cb (S12), and then the motor control value Cn is reset to 0 ( Next, a first drum operation failure determination process (S14) is executed, and then the process returns to S6.

  As shown in FIG. 15, in the first drum operation failure determination process of S14, first, it is determined whether or not the rotation direction when the rotation of the rotary drum 40 is stopped and the rotation direction when the rotation is started are the same direction. (S20). Specifically, based on the motor control value Cn, the direction that passes through the origin position P0 immediately before the rotation of the rotary drum 40 stops and the direction that passes through the origin position P0 immediately after the rotation of the rotary drum 40 starts are the same direction. It is determined whether or not.

  S20: In the case of Yes, it is calculated from the rotation angle θ (P0 → Ps) from the origin position P0 to the stop position Ps of the rotary drum 40 calculated from the motor stop side control value Ca and the motor start side control value Cb. It is determined whether or not the sum of the rotation angle θ (Ps → P0) from the stop position Ps of the rotating drum 40 to the origin position P0 is 360 degrees (S21), S21; If No, it is determined that the drum operation is defective (S23), and the process returns.

  In the case of S20; No, the rotation angle θ (P0 → Ps) from the origin position P0 to the stop position Ps of the rotating drum calculated from the motor stop side control value Ca and the motor start side control value Cb are calculated. It is determined whether or not the rotation angle θ (Ps → P0) from the stop position Ps to the origin position P0 of the rotary drum 40 coincides (S22). If S22: Yes, the process returns. If S22; It is determined that the drum operation is defective (S23), and the process returns.

  In FIG. 14, S8 can be omitted. Moreover, about S2, S3, S5, S7, S8, S10, and S12, you may utilize as what the motor control means 43 performs. In this case, S2, S3, S5, S8, and S10 are omitted. In S7, the latest motor control value Cn is read from the motor control means 43 and stored as the motor stop side control value Ca. In S12, the motor control means. 43, the latest motor control value Cn is read and stored as the motor start side control value Cb.

  Next, as shown in FIG. 16, in the second drum operation failure detection process, after the pachinko gaming machine 1 is turned on, first, the initial setting (S30) is executed, and the process waits until the stepping motor 41 starts to rotate. . When the stepping motor 41 starts to rotate (S31), the motor control value Cn is updated (S32). In S32, the motor control value Cn is calculated and updated based on the number and direction of pulses output by the motor control means 43 to the motor driver.

  In S30, when the rotating drum 40 is restored, the rotating drum 40 rotates, and when the origin position detecting means 44 detects the origin position P0, the motor control value Cn is reset to 0, and then the rotating drum 40 is set. When the stepping motor 41 rotates to stop the rotation at the position, the motor control value Cn is calculated and updated in the same manner as S32.

  Next, it is determined whether or not the origin position P0 of the rotary drum 40 has been detected (S33). If S33; No, the process proceeds to S37. S33: In the case of Yes, the latest motor control value Cn is stored as the motor 1 rotation control value Cc (S34), and then the motor control value Cn is reset to 0 (S35), and then the second drum operation A defect determination process (S36) is executed, and then the process proceeds to S37. In S37, it is determined whether or not the stepping motor 41 has stopped rotating. If S37; Yes, the process proceeds to S31, and if S37; No, the process proceeds to S32.

  As shown in FIG. 17, in the second drum operation failure determination process of S36, the rotation angle θ from the origin position P0 of the rotary drum 40 calculated from the motor 1 rotation control value Cc to the next origin position P0 (P0 → Whether or not (P0) is 360 degrees is determined (S40). If S40; Yes, the process returns. If S40; No, it is determined that the drum operation is defective (S41), and the process returns.

  In FIG. 16, S31, S32, S34, S35, and S37 may be used as those executed by the motor control means 43. In this case, S31, S32, S35, and S37 are omitted, and in S34, the latest motor control value Cn is read from the motor control means 43 and stored as the motor 1 rotation control value Cc.

  The first and second drum operation failure detection processes may be stopped after the drum operation failure is detected. However, if the drum operation failure is detected and then turned on after the power is turned off, the first and second drum operation failure detection processes may be resumed, or the information on the detected drum operation failure may be backed up. It is also possible to store the information at, and not use the information to resume.

Next, functions and effects of the effect display device 16 will be described.
By the first drum operation failure detection processing, the motor stop side control in the motor control unit 43 from the time when the origin position P0 is detected by the origin detection unit 44 to the time when the rotation of the stepping motor 41 is stopped using the existing origin detection unit 44. Based on the value Ca and the motor start side control value Cb in the motor control unit 43 from the start of rotation of the stepping motor 41 to the time of detection of the origin position P0 by the origin detection unit 44, the motor control unit 43 of the rotary drum 40 The drum operation failure due to the rotational deviation between the control rotation position and the actual rotation position is determined at the start of the rotation when the drum operation failure of the rotary drum 40 occurs, or the rotation of the rotation drum 40 where the drum operation failure occurs. It can be detected quickly and reliably at the start of the next rotation after stopping.

  In this case, even when the rotation direction when the rotation of the rotary drum 40 is stopped and the rotation direction when the rotation is started, the rotation direction when the rotation of the rotary drum 40 is stopped and the rotation direction when the rotation is started. When the rotation of the rotary drum 40 starts rotating, or when the rotation of the rotating drum 40 starts rotating after the stop of rotation, the drum starts rotating. It is possible to reliably detect malfunctions.

  In other words, when a drum operation failure occurs, the rotating drum 40 cannot be rotated at the selected and set drum stop position after starting the rotation and then stopped at the selected and set drum stop position. The drum 40 is awkwardly rotating, looks bad, and above all, even though it is not won in the big hit lottery, at least three specific symbols of the rotating drum 40 may be stopped and displayed in a straight line. If this happens, it will make the player suspicious, but it will be possible to take measures quickly.

  By the second drum operation failure detection process, the existing origin detection means 44 is used to rotate the drum one time in the motor control means 43 from the time when the origin position detection means 44 detects the origin position P0 until the next origin position P0 is detected. In accordance with the motor 1 rotation control value Cc corresponding to the above, the drum operation failure of the rotating drum 40 occurs due to the drum operation failure due to the rotation deviation between the control rotation position and the actual rotation position in the motor control means of the rotation drum 40 Can be detected quickly and reliably before the rotation stops. Then, by executing this second drum operation failure detection process together with the first drum operation failure detection process, the detection accuracy (detection speed) of the drum operation failure can be increased.

  As described above, in this stepping motor 41, it has been found that a malfunction of the drum occurs due to a meshing failure between the gear members 41g to 41j of the reduction gear mechanism 41f. It was also found that it is likely to occur during deceleration (when rotation stops). In this case, the first drum operation failure detection process can detect the drum operation failure at the start of the next rotation after the rotation stop where the drum operation failure of the rotation drum 40 has occurred. May occur at the time (at the start of rotation), and in this case, the second drum operation failure detection process may be detected at the start of rotation when the drum operation failure of the rotary drum 40 occurs. it can.

  Further, in this effect display device 16, since the stepping motor 41 has (built in) the reduction gear mechanism 41f, the resolution of the stepping motor 41 can be increased, and the stepping motor 41 can be downsized to reduce the stepping motor. The installation space of 41 is reduced, and the rotating drum 40 can be easily configured with a desired number, shape, size, and arrangement.

  Further, the rotary drum 40 is rotatably supported by the drum base member 46, and the origin detection means 44 is provided at the outer peripheral edge of the rotary drum 40 so as to protrude in a direction parallel to the rotational axis of the rotary drum 40. An optical sensor 42 having a shielding plate 40b, a light emitting portion 42a, and a light receiving portion 42b, and is attached to the drum base member 46 so that the shielding plate 40b passes between the light emitting portion 42a and the light receiving portion 42b. Since the optical sensor 42 is included, the arrangement and mounting of the origin detection means 44 (shielding plate 40b, optical sensor 42) can be simplified, and the rotating drum 40 can be configured with a desired number, shape, size, and arrangement. It becomes effective in doing.

  In the first and second drum operation failure detection processing, the position of the rotating drum 40 is displaced with respect to the output shaft 41a of the stepping motor 41 (as in this embodiment, the output shaft 41a of the stepping motor 41 is moved to the rotating drum 40. When directly connected, it is possible to cope with slippage of the output shaft 41a, that is, it is possible to detect a drum operation failure.

  In the second embodiment, the first drum operation failure detection process of the first embodiment is changed as shown in FIG. This first drum operation failure detection process is obtained by adding S50 and S51 to the first drum operation failure detection process of FIG. In the case of S21; No or S22; No, the process proceeds to S50, and the drum operation failure judgment value is calculated and updated (S50). Thereafter, it is judged whether or not the drum operation failure judgment value is greater than or equal to the set value (S51). If S51; No, the process returns. If S51; Yes, the drum operation is determined to be defective (S23), and the process returns.

  For example, in S50, the number of times S21; No, S22; No is counted, and in S51, it is determined whether or not the number of times is equal to or greater than the set number (two times). Alternatively, for example, in S50, the number of times S21; No, S22; No is counted in a set period (for example, while the rotating drum 40 is continuously stopped and started to rotate 10 times), and in S51, the number of times Is greater than or equal to the set number of times (three times).

  Thus, in the case of S21; No, S22; No, it is not immediately determined that the drum operation is defective, but it is possible to determine the drum operation failure more accurately from the ratio of S21; No, S22; No. For example, a step-out of the stepping motor 41 that occurs rarely can be prevented from being erroneously detected as a defective drum operation. Further, there is a possibility of recovery from a temporary drum operation failure. In this case, it is determined that the drum operation is defective, and it is possible to prevent a measure from being taken even if no countermeasure is required.

  In the third embodiment, the second drum operation failure detection process of the first embodiment is changed as shown in FIG. This second drum operation failure detection process is obtained by adding S60 and S61 to the second drum operation failure detection process of FIG. In the case of S40, the process proceeds to S60, where the drum operation failure determination value is updated (S60), and then it is determined whether or not the drum operation failure determination value is equal to or greater than the set value (S61). If S61 is Yes, it is determined that the drum operation is defective (S41), and the process returns. S60 and S61 are basically the same steps as S50 and S51 of FIG.

  In addition, even if the stepping motor 41 is driven after the rotation of the rotating drum 40 in which the drum operation failure has occurred, the rotating drum 40 may not be able to start the next rotation. As a countermeasure, when the rotation angle of the rotating drum 40 calculated from the motor 1 rotation control value Cb reaches 360 degrees, the origin position P0 of the rotating drum 40 is not detected, and the rotating drum 40 further detects the set angle ( For example, when the stepping motor 41 is controlled to rotate 90 degrees, 180 degrees, or 300 degrees, when the origin position P0 of the rotating drum 40 is not detected, it may be determined that the drum operation is defective. .
