All or any part of the unit 60 is a liquid crystal display that can be selectively switched between a drum display state in which the rotary drum 40 can be seen through and a drum shielding state in which the rotary drum 40 cannot be seen through, and controls the image display 18. The display control means 61 is configured on the image control board 28.

  The display unit 60 includes a liquid crystal display panel 62 and a liquid crystal light control panel 63 disposed on the rear side of the liquid crystal display panel 62. The liquid crystal panels 62 and 63 include three transparent panels 64 (glass substrates). 64). The liquid crystal display panel 62 and the liquid crystal light control panel 63 each have a deflection filter, a large number of liquid crystal cells, and transparent electrodes, and are configured to be in a completely transmissive state (transparent). It has a large number of color filters and is configured to be able to display effect images (moving images) in color.

  The display portion 60 (panels 62 to 64) has an outer peripheral portion fitted and held by the frame member 65 and faces forward from the display window 65 a inside the front end of the frame member 65. The frame member 65 is fixed to the drum case 50. Drum illumination is provided on the front side of the nine rotating drums 40, and a liquid crystal backlight is provided on the rear side of the display unit 60. The drum illumination and the liquid crystal backlight are used as a common illumination, and the illumination light reaches the display unit 60 (liquid crystal light control panel 63) and the nine rotating drums 40 (front cover 51) from between them. Can be configured.

  When the liquid crystal display panel 62 and the liquid crystal light control panel 63 are both in a completely transmissive state in all or an arbitrary part of the display unit 60, the drum display state is entered. Here, the rotating drum 40 is clearly seen in a completely transparent state. When the liquid crystal display panel 62 and the liquid crystal light control panel 63 are not completely transmitted, the drum is shielded. In addition, when the liquid crystal light control panel 63 is in a completely transmissive state in all or an arbitrary part of the display unit 60, if the liquid crystal display panel 62 is not in a completely transmissive state, an image displayed on the liquid crystal display panel 62 is displayed. Depending on the color tone or the like, either the drum display state or the drum shielding state is set. In this drum display state, the effect image is displayed somewhat unclear and the rotating drum 40 is displayed in a semi-transparent manner on the rear side. The

  As shown in FIG. 13, the effect display device 16 has the motor control means 43 for each of the nine rotating drums 40 from the time when the origin position detecting means 44 detects the origin position P0 to the time when the rotation of the stepping motor 41 is stopped. Of the rotating drum 40 based on the motor stop side control value Ca and the motor starting side control value Cb in the motor control means 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 means 44. There is provided a first drum operation failure detection means 70 capable of detecting a drum operation failure due to a rotational deviation between the rotational position on the control of the motor control means 43 and the actual rotation position. The first drum operation failure detection means 70 is configured on the image control board 28.

  The first drum operation failure detection means 70 is a rotating drum calculated from the motor stop side control value Ca when the rotation direction when the rotation of the rotary drum 40 is stopped and the rotation direction when the rotation starts. The rotation angle θ from the origin position P0 to the stop position Ps of 40 (P0 → Ps) and the rotation angle θ from the stop position Ps of the rotary drum 40 calculated from the motor start side control value Cb to the origin position P0 (Ps → If the sum of P0) is not 360 degrees, it is determined that the drum operation is defective.

  Further, the first drum operation failure detection means 70 is calculated from the motor stop side control value Ca when the rotation direction when the rotation of the rotary drum 40 is stopped and the rotation direction when the rotation is started are opposite to each other. The rotation angle θ (P0 → Ps) from the origin position P0 to the stop position Ps of the rotary drum and the rotation angle θ (Ps) from the stop position Ps of the rotary drum 40 to the origin position P0 calculated from the motor start side control value Cb. → If P0) does not match, it is determined that the drum operation is defective.

  Further, the effect display device 16 corresponds to one rotation of the drum in the motor control means 43 from the time when the origin position detecting means 44 detects the origin position P0 until the next origin position P0 is detected for each of the nine rotating drums 40. Second drum operation failure detection means capable of detecting a drum operation failure due to a rotational deviation between a control rotational position and an actual rotation position in the motor control means 43 of the rotary drum 40 based on the motor 1 rotation control value Cc to be performed. 71 is provided. The second drum operation failure detection means 71 is configured on the image control board 28.

  The second drum operation failure detecting means 71 is used when the rotation angle θ (P0 → P0) from the origin position P0 of the rotary drum 40 to the next origin position P0 calculated from the motor 1 rotation control value Cc is not 360 degrees. It is determined that the drum operation is defective.

  In this effect display device 16, when a drum operation failure is detected by the drum operation failure detection means 70 or 71, the display control means 61 includes the display unit 60 of the image display unit 18 of the rotating drum 40 with the drum operation failure. An image is displayed so that a part positioned on the front side is switched to and maintained in the drum shielded state, and a game effect (effect image) dedicated to defective drum operation different from normal is displayed in the part maintained in the drum shielded state. The display 18 is controlled.

  In this case, the display control means 61 is a game effect in place of the game effect displayed on the rotating drum 40 having the defective drum operation among the nine rotating drums 40 as the game effect dedicated to the defective drum operation, and the drum operation is defective. The game effect displayed on the rotary drum 40 is displayed as an image. In addition, when a drum operation failure is detected by the drum operation failure detection means 70 or 71, the motor control means 43 prevents the rotation drum 40 having the drum operation failure from rotating among the nine rotation drums 40. 41 is controlled.

  Next, specific processing executed by the display control unit 61, the motor control unit 43, and 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 game control board 22 and the effect control board 27 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 of the game effect patterns 1, 2, 3,... N shown in FIG. Is selected and set, and a variation effect start command including information on the game effect pattern is output to the image control board 28.

  The display / motor control process executed by the display control means 61 and the motor control means 43 is shown in the flowchart of FIG. Here, 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 depends on the direction of the pulse. And the rotation speed of each rotary drum 40 is controlled by the pulse frequency. The display area of the display unit 60 of the graphic image display 18 is composed of nine display areas 60a to 60i corresponding to the nine rotating drums 40, respectively.

  As shown in FIG. 15, in this display / motor control process, after the pachinko gaming machine 1 is turned on, first, the initial setting (S1) is executed. In this initial setting, the nine rotating drums 40 are restored, Therefore, each rotary drum 40 is rotated, the origin position P0 is detected by the origin detection means 44, and the rotation is stopped at a fixed position.

  Next, it is determined whether or not a change effect start command is received from the effect control board 27 (S2). If S2; No, the drum operation failure flag F is 1 (that is, the drum operation failure detection means 70 or 71, whether or not a drum operation failure is detected is determined (S3). In the case of S3; No, a normal standby display control process (S4) is executed, and the process returns to S2. In S4, as shown in FIG. The drum display state is set so that the rotary drum 40 is completely transparent.

  In the case of S3; Yes, the standby display control process (S5) for defective drum operation is executed, and the process returns to S2. The portion of the rotating drum 40 located on the front side of the rotating drum 40 in which the drum operation is poor is switched to and maintained in the drum shielding state, and the drum operation failure of the rotating drum 40 located on the rear side is maintained in this drum shielding state. If not, the rotation stop state is displayed in a pseudo manner. For example, when the rotating drum 40 on the rear side of the display area 60a has a defective drum operation, the display area 60a of the display section 60 is maintained in the drum shielding state as shown in FIG. At 60a, the rotation stop state of the rotary drum 40 that has stopped displaying the specific symbol ("7") is displayed in a pseudo manner as in FIG.

  Next, when the change effect start command is received from the effect control board 27 (S2; Yes), the change effect start command (game effect pattern) is analyzed (S6). Next, when the drum operation failure flag F is not 1 (S7; No), a normal effect motor control process (S8) and a normal effect display control process (S9) are executed, and the process proceeds to S12.

  In S8 and S9, after the nine rotary drums 40 start rotating from the state of FIG. 17 as shown in FIG. 19, the drum operation corresponding to the effect pattern selected and analyzed (analyzed in S6) The nine stepping motors 41 are controlled so as to rotate at the drum stop position selected and set (see FIG. 14), and the display corresponding to the selected effect pattern is displayed. Control is performed to execute the effect (see FIG. 14).

  In S9, as shown in FIG. 19, the entire display unit 60 is in a drum display state in which the rotary drum 40 is completely transparent, or as shown in FIG. 20, the entire display unit 60 is in a drum shielding state. Therefore, an effect image is displayed, or as shown in FIG. 21, the entire display unit 60 is in a drum display state in which the rotary drum 40 is semi-transparent, and the effect image is displayed somewhat unclearly there.

  Further, as shown in FIG. 22, a part of the display unit 60 (for example, the display area 60 f) is brought into a drum display state in which the rotary drum 40 is completely transparent, and the other part of the display unit 60 is shielded from the drum. Then, an effect image is displayed, and as shown in FIG. 23, a part of the display unit 60 (for example, display areas 60c, 60f, 60i) is in a drum display state in which the rotary drum 40 is completely transparent. At the same time, other than the part of the display unit 60, the drum display state in which the rotary drum 40 is semi-transparent is used.

  Each of the display effects of the plurality of types of game effect patterns has at least one of FIGS. Finally, as in FIG. 17, the entire display unit 60 is brought into a drum display state in which the rotary drum 40 is completely transparent, and in S8, the nine rotary drums 40 are set to the selected drum stop. Nine stepping motors 41 are controlled so as to stop the rotation at the position, and when winning in the big hit lottery, as shown in FIG. 24, as shown in FIG. 7 ") (two sets in FIG. 24) are stopped and displayed so as to be aligned.

  On the other hand, as shown in FIG. 15, when the drum operation failure flag F is 1 (S7; Yes), the drum operation failure effect motor control processing (S10) and the drum operation failure effect display control processing (S11) are performed. Once executed, the process proceeds to S12.

  In S10 and S11, the rotating drums 40 other than the rotating drums 40 with defective drum operation (for example, eight) are selected and set after starting to rotate as shown in FIG. 25 from the state of FIG. 18 (S6). The nine stepping motors 41 are controlled to rotate at the drum operation (see FIG. 14) corresponding to the effect pattern (analyzed in FIG. 14) and stop at the selected drum stop position, and the image display Control is performed so as to execute a display effect (see FIG. 14) for drum operation failure in place of the display effect corresponding to the effect pattern 18 selected and set.

  Most of the display effects executed in S11 are the same as the display effects executed in S9. For example, FIG. 20 and FIG. 22 are exactly the same. However, in FIG. 25 corresponding to FIG. 19, FIG. 26 corresponding to FIG. 21, and FIG. 27 corresponding to FIG. 23, in order to conceal the rotating drum 40 having the drum operation failure, the drum operation failure in the display unit 60. A portion located on the front side of the rotating drum 40 (for example, the display area 60a) is maintained in the drum shielding state, and the rotating operation when the rotating drum 40 located on the rear side is not defective is displayed in a pseudo manner. The In the case of FIGS. 26 and 27, it is desirable to display the rotating drum 40 in a semi-transparent manner in the case of FIGS. In the case of FIG. 26, it is desirable that a part of the effect image is displayed somewhat unclear similarly to FIG.

  Finally, as in FIG. 18, the portion of the display unit 60 located on the front side of the rotating drum 40 in which the drum operation is poor is maintained in the drum shielding state, and there, the drum of the rotating drum 40 located on the rear side thereof. Although the rotation stop state when there is no malfunction is displayed in a pseudo manner, the other drums are displayed in a drum display state in which the rotation drum 40 is completely transparent. The nine stepping motors 41 are controlled so as to stop the rotation at the selected drum stop position.

  Therefore, when winning in the big hit lottery, three specific symbols (“7”) are stopped and displayed so as to be aligned on a straight line. Here, as shown in FIG. 28, when the rotating drum 40 that stops and displays specific symbols arranged in a straight line is malfunctioning, a portion of the display unit 60 that is positioned on the front side of the rotating drum 40 that is malfunctioning (for example, In the display area 60a), the rotation stop state of the rotary drum 40 that has stopped displaying the specific symbol (“7”) is displayed in a pseudo manner as in FIG. In S12, it is determined whether or not a variable effect stop command is received from the effect control board 27. If S12; No, the process returns to S7, and if S12; Yes, the process returns to S2.

  The first drum operation failure detection process executed by the first drum operation failure detection unit 70 for each rotary drum 40 is shown in the flowcharts of FIGS. 29 and 30, and the second drum operation failure detection unit 71 is used for each rotation drum 40. FIG. 31 and FIG. 32 show the second drum operation failure detection process to be executed. The first and second drum operation failure detection processes are executed in 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. 29, in the first drum operation failure detection process, after the pachinko gaming machine 1 is turned on, first, initial setting (S20) is performed, and the process waits until the stepping motor 41 starts to rotate. When the stepping motor 41 starts to rotate (S21), the motor control value Cn is updated (S22). In S22 and subsequent S31, 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 S20, 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 S22. In S20, the drum operation failure flag F is basically reset to 0. However, even if the drum operation failure flag F (0 or 1) is adopted so that the drum operation failure flag F can be stored from the time when the power of the pachinko gaming machine 1 is turned off to the time when the power is turned on this time. Good.

  Next, it is determined whether or not the origin position P0 of the rotary drum 40 has been detected (S23). If S23; No, the process proceeds to S25. If S23; Yes, the motor control value Cn is reset to 0 ( S24), and then the process proceeds to S25. Next, it is determined whether or not the stepping motor 41 has stopped rotating (S25). If S25; No, the process returns to S22, and S22 to S25 are repeatedly executed.

  When the stepping motor 41 stops rotating (S25; Yes), the latest motor control value Cn is stored as the motor stop side control value Ca (S26), and then the motor control value Cn is reset to 0 (S27). Wait until the motor 41 starts rotating. When the stepping motor 41 starts to rotate (S28; Yes), the motor control value Cn is calculated and updated (S29). Next, it is determined whether or not the origin position P0 of the rotating drum 40 is detected (S30), S30; No In this case, the process returns to S29, and S29 to S30 are repeatedly executed.

  When the origin position P0 of the rotary drum 40 is detected (S30; Yes), the latest motor control value Cn is stored as the motor start side control value Cb (S31), and then the motor control value Cn is reset to 0 ( Next, a first drum operation failure determination process (S33) is executed, and then the process returns to S25.

  As shown in FIG. 30, in the first drum operation failure determination process of S33, 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. (S40). 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.

  S40: 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 (S41), S41; If No, it is determined that the drum operation is defective, the drum operation failure flag F is set to 1 (S43), and the process returns.

  In the case of S40; No, the rotation angle θ (P0 → Ps) from the rotation drum origin position P0 to the stop position Ps 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 (S42). If S42: Yes, the process returns. If S42; It is determined that the drum operation is defective, the drum operation failure flag F is set to 1 (S43), and the process returns.

  Next, as shown in FIG. 31, in the second drum operation failure detection process, after the pachinko gaming machine 1 is turned on, first, the initial setting (S50) is executed, and the process waits until the stepping motor 41 starts to rotate. . When the stepping motor 41 starts to rotate (S51), the motor control value Cn is updated (S52). In S52, 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 S50, when the rotating drum 40 is restored, the rotating drum 40 is rotated, 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 as in S52. In addition, the drum operation failure flag F is basically reset to 0. However, even if the drum operation failure flag F (0 or 1) is adopted so that the drum operation failure flag F can be stored from the time when the power of the pachinko gaming machine 1 is turned off to the time when the power is turned on this time. Good.

  Next, it is determined whether or not the origin position P0 of the rotary drum 40 has been detected (S53). If S53; No, the process proceeds to S57. S53: If Yes, the latest motor control value Cn is stored as the motor 1 rotation control value Cc (S54), then the motor control value Cn is reset to 0 (S55), and then the second drum operation A defect determination process (S56) is performed, and then the process proceeds to S57. In S57, it is determined whether or not the stepping motor 41 has stopped rotating. If S57; Yes, the process proceeds to S51, and if S57; No, the process proceeds to S52.

  As shown in FIG. 32, in the second drum operation failure determination process of S56, 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 → P0) is determined to be 360 degrees (S60). If S60; Yes, the process returns. If S60; No, it is determined that the drum operation is defective, and the drum operation failure flag F is set to 1. Set (S61) and return.

  The first and second drum operation failure detection processes may be stopped after the drum operation failure is detected. However, when a power failure is detected and the power is turned on after the power is turned off, the first and second drum operation failure detection processes may be resumed, and 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 disposing the transmissive display unit 60 of the image display 18 on the front side of the nine rotating drums 40, various game effects can be executed, and the drum operation failure detection means 70 and 71 perform drum operation. When a defect is detected, the image display 18 is used to switch and maintain the portion of the display unit 60 of the image display 18 that is located on the front side of the rotating drum 40 that is defective in drum operation in a drum shielding state. Thus, it is possible to conceal the rotating drum 40 with the defective drum operation so that the player can not see the defective game production due to the defective drum operation as it is. It is possible to prevent specific symbols of the rotating drum 40 from being stopped and displayed side by side in a straight line (giving the player suspicion).

  Moreover, in the portion of the display unit 60 of the image display 18 that is maintained in the drum shielding state, a game effect dedicated to defective drum operation that is different from the normal one is displayed, so that a game effect that covers defects due to defective drum operation is displayed. This can be executed, and the production effect can be maintained without deteriorating. If a drum operation failure is detected by the drum operation failure detection means 70, 71, the rotating drum 40 having a defective drum operation among the nine rotating drums 40 is not rotated, thereby adversely affecting the drum operation failure of the rotating drum 40 (for example, Occurrence of abnormal noise and further failure due to rotation of the rotating drum 40 with defective drum operation can be prevented.

  By displaying on the display unit 60 of the image display 18 a game effect instead of the game effect displayed on the rotating drum 40 having the defective drum operation among the nine rotating drums 40 as the game effect dedicated to the drum operation failure, It is possible to reliably execute a game effect that covers a defect caused by a defective drum operation, and to further display a game effect displayed on the rotating drum 40 (the rotating drum 40 that has a defective drum operation), thereby causing a defective drum operation. It is possible to show the player the game effect that covers the defect caused by the game like a normal game effect.

  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.

  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.

  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.

  The second embodiment is obtained by changing the processing and control executed by the display control unit 61 in the first embodiment. In the display control means 61, when a drum operation failure is detected, as shown in FIG. 33, a portion (display region 60a) of the display unit 60 of the image display 18 that is positioned on the front side of the rotating drum 40 with the drum operation failure. ) Is switched to the drum shield state, and as a game effect dedicated to defective drum operation, the current stage in the game effect (a plurality of types of effect modes) is not displayed as a pseudo game display displayed on the rotating drum 40. For example, the image display 18 is controlled so as to display “XXX stage”) with characters.

  The third embodiment is obtained by changing the processing and control executed by the motor control unit 43 in the first embodiment. In this motor control means 61, when a drum operation failure is detected, after the rotation drums 40 other than the drums 40 (for example, 8 drums) having the drum operation failure start to rotate, as shown in FIG. The nine stepping motors 41 are controlled so as to rotate by the drum operation for the defective drum operation instead of the drum operation corresponding to the effect pattern, and stop at the selected drum stop position.

  For example, as shown in FIG. 35, when no drum operation failure is detected, the three rotary drums 40 including the rotary drum 40 on the rear side of the display area 60a are identified by the drum operation corresponding to the selected effect pattern. When the symbols ("7") are stopped and displayed so as to be aligned in a straight line, if the rotating drum 40 on the rear side of the display area 60a becomes defective in the drum operation and the display area 60a is switched to a drum shield, As in the second embodiment, when a game effect other than the pseudo display of the game effect displayed on the rotary drum 40 is displayed, specific symbols (“7”) of the three rotary drums 40 are aligned. Will stop appearing.

  Therefore, as shown in FIG. 36, three drums other than the rotating drum 40 with the defective drum operation (the rotating drum 40 on the rear side of the display area 60a) are generated by the drum operation for the defective drum operation corresponding to the selected production pattern. The specific design ("7") of the rotary drum 40 can be stopped and displayed so as to be aligned on a straight line. Note that the drum operation for the drum operation failure is set in advance based on the normal drum operation and the position of the rotating drum 40 with the drum operation failure, or is set when the drum operation failure is detected. Shall be.

  In the fourth embodiment, the processing and control executed by the display control unit 61 in the first embodiment is changed. In the display control means 61, when a drum operation failure is detected, as shown in FIG. 37, a plurality of rotating drums 40 (drum operation) including the rotating drum 40 having a drum operation failure in the display unit 60 of the image display 18 are displayed. A portion (display areas 60a, 60b, 60c) located in front of the non-defective rotating drum 40) is switched to and maintained in the drum shielding state, so that a game effect dedicated to defective drum operation is displayed. The display 18 is controlled.

  In the fifth embodiment, the processing / control executed by the display control means 61 in the first embodiment is changed. In this display control means 61, when a drum operation failure is detected, as shown in FIG. 38, the entire display unit 60 of the image display 18 is switched to the drum shielded state and maintained. As the game effects, the image display 18 is controlled so that the game effects displayed on all nine rotating drums 40 are displayed in a pseudo manner.

  In the sixth embodiment, the processing / control executed by the display control means 61 in the first embodiment is changed.
