Description

  The present invention relates to a gaming machine such as a pachinko gaming machine or a slot machine installed in a game hall such as a gaming hall.

  Patent Document 1 discloses a game provided with a rendering device that is disposed in front of a game board and performs a character effect that indicates a result of a hit determination by operating a character, and an electric decoration board that controls the rendering device. The machine is listed. The character is connected to the motor, and moves between the winning position and the winning position, which is the origin position, under the control of the motor by the illumination board. The effect device is provided with a photosensor for detecting whether or not the character is located at the origin position. In order to allow the movement of the character to start from the origin in the effect production, the decoration board is displayed by the photo sensor at the time of the start of the effect production or at the time of displaying the demonstration screen displayed while the game is stopped. It is determined whether or not it is located at the origin position. If it is not located at the origin position, the character is returned to the origin position. In this process, the illumination board moves the character to the origin position by the motor, and stops the motor when the photo sensor detects that the character has reached the origin position.

JP 2009-106546 A

  When the game is performed, the movable body is moved or rotated as described in Patent Document 1 within a range including the predetermined first position and the predetermined second position, and the movable body is in the predetermined first position. In the gaming machine having the detecting means for detecting the movement, the driving of the stepping motor is controlled, and the movable body moved or rotated to the predetermined second position is moved or rotated to the predetermined first position, and then the predetermined stop position. Some of them have a control unit that executes a stop process to be stopped. The control unit starts driving the stepping motor when there is a movable body at the predetermined second position, and the control unit corresponds to a predetermined amount corresponding to the amount of movement or rotation of the movable body from the predetermined second position to the predetermined first position. Assuming that there are variations in the shape of the movable body and assembly errors in the basic number of steps, the number of steps obtained by adding a predetermined number of additional steps is taken as the number of normal driving steps, and the cumulative number of steps from the start of driving the stepping motor is When the detection means detects the movable body before the normal drive step number is reached, or when the detection means does not detect the movable body and the cumulative step number reaches the normal drive step number, the movable body stop processing is performed. Execute.

  However, when the control unit is applied to the pachinko gaming machine of Patent Document 1, in a state where the photosensor cannot detect a character, for example, in a state where an abnormality (such as a short circuit of a chip capacitor) occurs in the photosensor, Since the character cannot be detected, the control unit unnecessarily rotates the stepping motor until the end of driving for the number of normal driving steps after the character reaches the origin position every time the character is returned to the origin position. Move the movable body unnecessarily. In this case, in order to reliably stop the character at the origin position, the pachinko gaming machine can be provided with a stopper that stops the movement of the character by contacting the character that is going to move beyond the origin position. Since the control unit tries to move the character unnecessarily even after the character comes into contact with the stopper, the character may be damaged.

  This invention is made | formed in view of the said actual condition, and it aims at providing the game machine which prevents trying to move or rotate a movable body unnecessarily.

  In order to achieve the above object, a gaming machine of the present invention includes a movable body, a movable body detection means, a stepping motor, a drive control means, and a mode change means.

  The movable body is supported by the gaming machine main body so as to be rotatable or movable within a range including the first position and the second position. The movable body detection means is fixed to the gaming machine body in order to detect the movable body at the first position. The stepping motor can be rotated by the number of steps, and is connected to the movable body to drive the movable body. The drive control means controls the stepping motor to rotate or move the movable body at the second position toward the first position. The stop control means is selectively set to the normal mode and the error mode, and controls the stepping motor to execute the stop process of the movable body. The mode change means changes the stop control means from the normal mode to the error mode.

  Further, the normal mode stop control means sets the number of steps obtained by adding a predetermined number of additional steps to the number of basic steps corresponding to the amount of rotation or movement of the movable body from the second position to the first position as the number of normal driving steps. When the movable body detection means detects the movable body before the cumulative number of steps from the start of driving the stepping motor by the drive control means reaches the normal drive step number, or the movable body detection means detects the movable body. When the cumulative number of steps reaches the number of normal driving steps, the movable body stop process is executed. The mode change means changes the stop control means from the normal mode to the error mode when the movable body detection means does not detect the movable body even when the cumulative step number reaches the normal drive step number in the normal mode. The error mode stop control means executes the stop process of the movable body when the cumulative number of steps from the start of driving of the stepping motor by the drive control means reaches the basic step number.

  In the above configuration, when the movable body detection unit cannot detect the movable body, the mode change unit changes the stop control unit from the normal mode to the error mode. The stop control means in the error mode controls the stepping motor to execute the movable body stop processing when the cumulative number of steps from the start of driving of the stepping motor by the drive control means reaches the basic step number. That is, after the stop control unit is changed to the error mode, the stop control unit executes the stop process without driving the stepping motor by the number of additional steps by the drive control unit. For this reason, since the stepping motor is not driven unnecessarily, it is possible to prevent the movable body from being moved or rotated unnecessarily.

  According to the present invention, it is possible to prevent the movable body from being moved or rotated unnecessarily.

(Discharge control device 71)
The payout control device 71 is equipped with a circuit board (payout control board) on which a payout control CPU 80 is mounted. The payout control CPU 80 also includes a CPU core (not shown), like the main control CPU 73, and includes a ROM 81 and a RAM 82. It is configured as an LSI together with a semiconductor memory. The payout control CPU 80 controls the game ball payout operation based on the prize ball instruction command (payout command transmission signal) received from the main control CPU 73, and causes the specified number of game balls to be paid out. The main control CPU 73 generates and outputs a prize ball information signal as an external information signal separately from the prize ball instruction command. Specifically, the main control CPU 73 generates and outputs a prize ball information signal as an external information signal every time the designated number reaches a predetermined number (for example, 10). The payout control CPU 80 also generates and outputs a prize ball information signal as an external information signal every time the total number of payouts reaches a predetermined number (for example, 10).

  The game balls replenished from the ball supply path (not shown) of the game hall are stored in a prize ball tank (not shown), and flow down a prize ball bowl (not shown) and introduced into a prize ball case (not shown). , And supplied to the upper plate 10 from the prize ball case.

  The prize ball case is provided with a payout motor (for example, a stepping motor) 83, and the payout control device 71 (payout control board unit 63) is provided with a drive circuit (not shown) of the payout motor 83. The payout control device 71 rotationally drives the payout motor 83 based on the prize ball instruction command received from the main control CPU 73, and pays out the designated number of game balls from the prize ball case. The game balls that have been paid out flow down to the front board 4 through a payout passage (not shown).

  A payout counting switch 84 is installed on the downstream side of the payout motor 83, and when a prize ball is actually paid out by driving the payout motor 83, a count signal from the payout count switch 84 is transmitted to the payout control device 71. The payout control CPU 80 detects the actual payout number and the out-of-ball state based on the received count signal, and manages the payout of game balls.

  A tray full tank switch 85 is installed in the supply path of game balls to the upper plate 10 (shown in FIG. 1), and when the lower plate 11 (shown in FIG. 1) is full of game balls, the plate full tank switch 85 is turned on. It becomes ON, and a full tank detection signal is transmitted to the payout control device 71. The payout control CPU 80 that has received the full tank detection signal temporarily holds the prize ball operation according to the prize ball instruction command received from the main control CPU 73, and stores the unpaid prize ball remaining number in the RAM 82. The RAM 82 can be backed up even when the power is cut off, so that even if a power outage (including momentary power outage) occurs during the game, the information on the number of remaining unpaid prize balls will not be lost. .

  The firing device 19 (shown in FIG. 2) is provided with a firing motor 86 and a ball feed solenoid 87, and the firing handle 18 (shown in FIG. 1) has a firing volume 88, a touch sensor 89, a firing stop switch 90, Is provided. The ball feed solenoid 87 sends game balls that have flowed down from the upper plate 10 (shown in FIG. 1) one by one to the launch position, and the launch motor 86 launches the game balls sent to the launch position. In addition, the launch interval of game balls is, for example, about 0.6 seconds (within 100 per minute).

  The firing volume 88 transmits a firing force instruction signal proportional to the rotational operation amount (stroke) of the firing handle 18 (shown in FIG. 1) to the dispensing control device 71. The touch sensor 89 detects that the player's body is touching the firing handle 18 from the change in capacitance, and transmits the detection signal to the payout control device 71. The firing stop switch 90 transmits a firing stop signal (contact signal) to the payout control device 71 when operated by the player.

  When the player rotates the firing handle 18, a firing force instruction signal corresponding to the amount of rotational operation is transmitted from the firing volume 88 to the payout control device 71. The payout control CPU 80 controls driving of the firing motor 86 based on the received firing force instruction signal. Thereby, the launch strength of the game ball is adjusted according to the operation amount of the player. However, the payout control CPU 80 stops driving the firing motor 86 when the detection signal from the touch sensor 89 is off (low level) and when the firing stop signal is input from the firing stop switch 90. In addition, the payout control CPU 80 stops the driving of the firing motor 86 when the CR unit 50 is not connected to the pachinko machine P.

  When the ball lending switch 12 or the return switch 13 is operated, the operation signal is transmitted to the CR unit 50 via the relay board 91. From the CR unit 50, a frequency signal indicating the remaining frequency of the valuable medium is transmitted to the frequency display device 14 via the relay substrate 91.

(Sub-control device 72)
The sub-control device 72 is equipped with a circuit board (composite sub-control board) on which an effect control CPU (drive control means, stop control means, mode change means) 92 is mounted. The effect control CPU 92 is also connected to the main control CPU 73. Similarly, it includes a CPU core (not shown) and is configured as an LSI together with semiconductor memories such as ROM 93 and RAM 94. The sub-control device 72 is equipped with an input / output driver and various peripheral ICs (both not shown).

  The ROM 93 of the sub-control device 72 stores an effect control program related to effect control and a plurality of effect patterns, and the effect control CPU 92 transmits a variation pattern command transmitted from the main control CPU 73 in accordance with the stored effect control program. Based on the above, one effect pattern is selected from the plurality of effect patterns, and effect control by the effect display device 31, the various lamps 25 and 60, the sound generator 97, and the shutter accessory 100 is executed. The effect display device 31 includes an image processor, a liquid crystal, and the like, and the sound generation device 97 includes a sound processor, a speaker 22, and the like. For the production control, the display control of the image on the production display device 31, the light emission control of the various lamps 25, 60, the sound generation control from the speaker 22, and the shutter accessory 100 (the right shutter accessory 100a and the left shutter accessory 100b). ) Drive control (specifically, drive control of the stepping motor 103 of the right shutter accessory 100a and drive control of the stepping motor 142 of the left shutter accessory 100b). Note that the image processor and the sound processor may be provided in the sub-control board unit 64.

  In the ROM 93, a basic step number storage area is set in which the basic step number used when the effect control CPU 92 performs drive control of the right shutter accessory 100a and drive control of the left shutter accessory 100b is stored. The number of basic steps means that the simulation results during the design of the pachinko machine P and the test results of prototypes during mass production trials are ideal when there is no variation in the shape of the shutter part 120 or assembly errors. By driving (reversing) the stepping motor 103 by the control CPU 92, the shielding side index detection sensor 117 is in the shielding direction (in the right shutter accessory 100a, the X1 direction shown in FIGS. 5 to 9 (hereinafter simply referred to as the X1 direction)). The detection of the shielding side index 131 of the moving shutter unit 120 starts from the shielding position (second position) shown in FIG. 9B, and the opening side index detection sensor 112 opens (in the right shutter accessory 100a, FIGS. A shutter unit that moves in the X2 direction (hereinafter simply referred to as the X2 direction) shown in FIG. Figure 9 (a) to the open position shown to start detection of the open side index 128 of 20 up (first position), is the step number of the stepping motor 103 corresponding to the movement amount when the shutter unit 120 is moved. In the present embodiment, 400 steps are stored as the number of basic steps.

  The ROM 93 is set with an additional step number storage area in which the additional step number is stored. The number of additional steps means that when the effect control CPU 92 reverses the stepping motor 130 by the number of basic steps and moves the shutter part 120 at the shielding position in the opening direction, the reverse of the number of basic steps is completed. When the open side index detection sensor 112 does not detect the open side index 128, the driving of the stepping motor 103 for causing the open side index detection sensor 112 to detect the open side index 128 after completion of the reverse rotation for the number of basic steps. The maximum number of steps allowed. In the present embodiment, 400 steps having the same number of steps as the number of basic steps are stored. Note that after the reverse rotation for the number of basic steps of the stepping motor 103 is completed, the movement of the movable body accompanying the reverse rotation within the number of additional steps of the stepping motor 103 by the effect control CPU 93 is referred to as a margin operation.

  The RAM 94 of the sub-control device 72 stores a count value of the number of drive steps of the stepping motor 103 counted by the effect control CPU 92 in drive control of the right shutter accessory 100a and drive control of the left shutter accessory 100b described later. A value storage area is set. In the count value storage area in the initial state immediately after the sub control device 72 is supplied with power, 0 is stored as the count value. Further, for each of the right shutter accessory 100a and the left shutter accessory 100b, a flag storage area for storing an index error flag that is set to ON in the case of an index error state described later is set.

  The drive control of the right shutter accessory 100a and the drive control of the left shutter accessory 100b executed by the effect control CPU 92 include an effect process and an open side index detection process, respectively, and the open side index detection process is a push-in process (stop process). Including.

  In the effect process, the effect control CPU 92 selects one effect pattern from a plurality of effect patterns stored in the ROM 93 based on the variation pattern command transmitted from the main control CPU 73, and determines a predetermined according to the selected effect pattern. A pulse signal is output to the stepping motor 103 in accordance with an excitation pattern for forward rotation or an excitation pattern for reverse rotation, the drive of the stepping motor 103 is controlled, the stepping motor 103 is rotated forward or backward, and the shutter unit 120 is moved. It is moved from the stop position, and reciprocated between the open position and the shield position. In the present embodiment, the effect patterns selected in the effect processes of the drive control of the right shutter accessory 100a and the drive control of the left shutter accessory 100b are the shutter portions 120 of the right shutter accessory 100a and the left shutter accessory 100b. Is an effect pattern that reciprocates between the shielding position and the opening position at the same timing. Therefore, in the shutter accessory 100, the shutter part 120 of the right shutter accessory 100a and the left shutter accessory 100b are both in the shielding position, and the shielding state in which the lower part of the effect display device 31 is shielded from the player, Both the shutter part 120 of the right shutter accessory 100a and the left shutter accessory 100b are in the open position, and the state transition is repeated between the open state where the lower part of the effect display device 31 is opened to the player, An effect that enhances the interest of the player can be performed. Regardless of which effect pattern is selected, the effect control CPU 92 detects the shield-side index output from the shield-side index detection sensor 117 so that the shutter unit 120 stops at the shield position at the end of the effect process. When the reception of the signal is started, the stepping motor 103 is stopped.

  The effect control unit CPU 92 executes an open side index detection process after the effect process is finished, and returns the shutter unit 120 from the shield position to the open position. In the opening side index detection process, the effect control unit CPU 92 performs an index detection process with margin operation (hereinafter referred to as an index detection process with margin) and an index detection process without margin operation (referred to as an index detection process without margin). Run selectively. In the opening side index detection process, the effect control CPU 92 first determines whether or not the index error flag in the RAM 94 is set to ON, and if it is OFF, executes the index detection process with margin. On the other hand, if it is on, the marginless index detection process is executed.

  In the index detection process with a margin, the effect control CPU 92 outputs a pulse signal for reversing the stepping motor 103 to reverse the stepping motor 103 and move the shutter unit 120 in the opening direction. The effect control CPU 92 counts the number of pulses of the output pulse signal as the number of driving steps of the stepping motor 103. Specifically, the effect control CPU 92 adds 1 to the count value stored in the count value storage area of the RAM 94 and stores it every time one pulse signal is output. Further, every time one pulse signal is output, it is determined whether or not the open side index detection sensor 112 has detected the open side index 128 based on whether or not the open side index detection signal is received. When the open side index detection signal is received, it is determined that it has been detected, and the push-in process is executed. On the other hand, if the open side index detection signal has not been received, it is determined that the open side index detection signal has not been detected, and the count value (count step number) stored in the RAM 94 is the number of steps obtained by adding the additional step number to the basic step number. It is determined whether or not a certain number of normal driving steps has been exceeded. If not, the output of a pulse signal for reversing the stepping motor 103 is repeated. On the other hand, if it has exceeded, even if the production control CPU 92 drives the stepping motor 103 by the number of normal drive steps, the open side index detection sensor 112 cannot detect the open side index 128, that is, the index error state. The index error flag of the indicated RAM 94 is set to ON, and the push-in process is executed.

  In the marginless index detection process, the effect control CPU 92 outputs a pulse signal that reversely rotates the stepping motor 103, reverses the stepping motor 103, and moves the shutter unit 120 in the opening direction. The effect control CPU 92 counts the number of pulses of the output pulse signal as the number of driving steps of the stepping motor 103. Specifically, the production control CPU 92 determines whether or not the count value (number of count steps) stored in the RAM 94 exceeds the basic number of steps every time one pulse signal is output. Repeats the output of the pulse signal. On the other hand, if it has exceeded, push-in processing is executed. That is, in the marginless index detection process, the effect control CPU 92 performs the pushing process without reversing the stepping motor 103 by the number of basic steps and without reversing the number of additional steps. Don't do it.

  As described above, the effect control CPU 92 changes the mode of the effect control CPU 92 from the normal mode that executes the index detection process with margin to the error mode that executes the index detection process without margin by setting the error flag to ON. Functions as a mode change means.

  In the push-in process, the effect control CPU 92 outputs a pulse signal that reverses the stepping motor 103 by a predetermined number of push steps, that is, 10 steps in this embodiment (that is, a pulse signal of 10 pulses according to the excitation pattern for reverse rotation) Thereafter, the driving of the stepping motor 103 is stopped and the shutter unit 120 is stopped. Thereby, when the shutter part 120 is located in the open position, the shutter part stops at the origin position shown in FIG. 9C which is further moved in the open direction (X2 direction). For this reason, even if the shutter unit 120 moves slightly in the shielding direction (X1 direction) due to vibrations transmitted from the outside to the pachinko machine P after the shutter unit 120 stops, the open side index detection sensor The state where 112 detects the open side index 128 can be reliably maintained. Therefore, in the index detection process with margin, the maximum number of steps driven by the stepping motor 103 is pushed into 800 steps of the normal drive step number (the number of steps obtained by adding 400 steps of the additional steps to 400 steps of the basic steps). It becomes 810 steps which added 10 steps of the number of steps. In the marginless index detection process, the maximum number of steps driven by the stepping motor 103 is 410 steps obtained by adding the pushing step number of 10 steps to the basic step number of 400 steps.

  The effect control CPU 92 detects the opening side index detection sensor 112 from the opening side index detection sensor 112 after the driving control of the right shutter part 100a and the left shutter part 100b is finished and at the end of the change of the first special symbol or the second special symbol. When the signal is not received, that is, when the open side index detection sensor 112 does not detect the open side index 128, the origin return process for reversing the stepping motor 103 by a predetermined number of steps is executed.

(Output to the outside)
Various external information signals generated in the main control device 70 and the payout control device 71 are output from the external information terminal board 65 to the outside. The signals output from the external information terminal board 65 are totaled, for example, by a hall computer 68 in a game hall.

[Open side index detection processing]
Next, the opening side index detection process executed by the effect control CPU 92 will be described with reference to the flowchart of FIG.

  When the opening side index detection operation is started, the effect control CPU 92 determines whether or not the index error flag of the RAM 94 is set to ON. When set to on (step S1: YES), the marginless index detection process is executed. On the other hand, when set to off (step S1: NO), the margined index detection process is executed, This process ends.

[Index detection process with margin]
Next, the margined index detection process executed by the effect control CPU 92 will be described with reference to the flowchart of FIG.

  In step S11, the effect control CPU 92 outputs a pulse signal that reverses the stepping motor 103 by one step, moves the shutter unit 120 in the opening direction, and proceeds to step S12.

  In step S <b> 12, the effect control CPU 92 counts the number of pulses output to the stepping motor 103 as the number of driving steps of the stepping motor 103, specifically, 1 is added to the count value stored in the count value storage area of the RAM 94. Are added and stored, and the process proceeds to step S13.

  In step S <b> 13, whether the open side index detection sensor 112 detects the open side index 128 of the shutter unit 120 based on whether or not the open side index detection signal output from the open side index detection sensor 112 is received. If it is determined and detected (step S13: YES), the process proceeds to step S16. On the other hand, when not detecting (step S13: NO), it transfers to step S14.

  In step S14, it is determined whether or not the count value stored in the count value storage area of the RAM 94, that is, the counted step number (count step number) exceeds the normal drive step number. If not, the process proceeds to step S11.

  In step S15, the index error flag is set to ON, and the process proceeds to step S16.

  In step S16, the pushing process is executed, the stepping motor 103 is reversed by the number of pushing steps to stop the stepping motor, the shutter unit 120 is stopped, and this process is terminated.

[No margin index detection processing]
Next, the marginless index detection process executed by the effect control CPU 92 will be described with reference to the flowchart of FIG. Steps S21 to S22 and S24 are the same as steps S11 to S12 and S16 in the index detection process with a margin, and thus the description thereof is omitted.

  In step S23, the effect control CPU 92 determines whether or not the count value stored in the count value storage area of the RAM 94, that is, the counted step number (count step number) exceeds the normal drive step number. If (step S23: YES), the process proceeds to step S24, and if not exceeded (step S23: NO), the process proceeds to step S21.

  In the present embodiment, when the effect control CPU 92 controls the effect by the shutter accessory 100 based on the variation pattern command transmitted from the main control CPU 93, the open side index detection sensor 112 can detect the open side index 128. In the state, that is, when the index error flag is OFF, the index detection process with margin is selectively executed in the open side index detection process.

  In addition, when the open side index detection sensor 112 enters an index error state in which the open side index 128 cannot be detected due to, for example, a short circuit of the chip capacitor, the first shutter accessory 100 produces an effect. In the open side index detection process in the control (drive control of the shutter accessory 100), the index detection process with margin is selectively executed, so the effect control CPU 92 adds the stepping motor 103 to the number of normal drive steps (the number of basic steps). The pushing process is executed after driving 800 steps (the number of steps obtained by adding the number of steps). Therefore, before the effect control CPU 92 finishes driving the number of normal driving steps of the stepping motor 103, the shutter unit 120 reaches the open position and passes through the open position, as shown in FIG. Even after the right side surface of the pedestal portion 122 of the shutter portion 120 contacts the stopper 110, the effect control CPU 92 drives the stepping motor 103 to move the shutter portion until the drive for the number of normal drive steps is completed. Therefore, elastic deformation of the shutter unit 120 and idle rotation of the stepping motor 103 occur (if these occur frequently, damage to the shutter unit 120 and failure of the stepping motor 103) occur. However, in this margined index detection process, the effect control CPU 92 sets the index error flag of the RAM 94 to ON, so that the effect control by the shutter accessory 100 executed by the effect control CPU 92 on and after the next time (the shutter accessory 100 In the open side index detection process in the drive control), the index detection process without margin is selectively executed. In the marginless index detection process, the effect control CPU 92 executes the push-in process without reversing the stepping motor 103 by the number of basic steps and then reversing the number of additional steps. Therefore, in the opening side index detection processing after the next time, since the margin operation is not performed on the shutter unit 120, it is possible to prevent the shutter unit 120 from being moved unnecessarily, and the shutter unit 120 can be used as the stopper 110. It is possible to prevent damage caused by trying to move the contact after contact, or failure caused by the idling of the stepping motor 103.

  Further, as the number of basic steps, as shown in FIG. 9B, the shielding-side index detection sensor 117 starts detecting the shielding-side index 131 of the shutter unit 120 that moves in the shielding direction by driving the stepping motor 103 by the effect control CPU 92. The movement amount when the shutter unit 120 moves from the shield position to the open position shown in FIG. 9A where the open side index detection sensor 112 starts to detect the open side index 128 of the shutter unit 120 moving in the open direction. Since the number of steps of the corresponding stepping motor 103 is set, even when the marginless index detection processing is selectively executed in the open side index detection processing, the driving for the number of basic steps of the stepping motor 103 is performed. By the shutter unit 120 It can be moved in the vicinity of the open position.

  When the open side index detection sensor 112 is in a state where the open side index 128 cannot be detected, the effect control CPU 92 executes the above-described origin return process after the drive control and at the end of the change. However, in the origin return process, the number of steps that the effect control CPU 92 reverses the stepping motor 103 is such that the shutter unit 120 and the stepping motor 103 are moved in the X2 direction after the shutter unit 120 is brought into contact with the stopper 110 and moved. Is set to a relatively small number of steps, for example, 10 steps.

  In the present embodiment, the effect control CPU 92 stops the shutter unit 120 at the shielding position at the end of the effect processing of the right shutter accessory 100a and the left shutter accessory 100b, and stores the basic step number in the ROM 93 as a fixed value. Although the aspect which memorize | stores was demonstrated, the production | presentation control CPU92 may stop the shutter part 120 at the approximate middle point of a shielding position and an open position at the time of completion | finish of production processing. In this case, the effect control CPU 92 stores, in the RAM 94, the number of steps in which the stepping motor 103 is rotated forward and backward during the effect process, and opens from the position where the shutter unit 120 is stopped based on the stored number of steps. The number of steps required to move to the position is calculated (for example, 200 steps when the shutter unit 120 is stopped at a substantially intermediate point between the shielding position and the open position), and the calculated number of steps is used as the basic number of steps. It may be used to perform open side index detection processing.

  In the present embodiment, the mode in which the open-side index detection sensor 112 detects the open-side index 128 of the shutter unit 120 in the open position has been described, but instead of this, the shutter 121 of the shutter unit 120 in the open position or A sensor that detects the base portion 122 and outputs a detection signal to the sub-control device 72 may be provided. In this case, the trouble of providing the open side index 128 can be saved.

  The execution timing of the open side index detection process can be set as appropriate. For example, when a demonstration video (demonstration screen) such as a video that introduces the contents of a game in a standby state where no game is being performed is displayed on the effect display device 31, the open side index is displayed every predetermined time in the so-called demonstration screen. You may perform a detection process.

  Next, a second embodiment will be described. This embodiment is different from the first embodiment in that the present invention is applied to the rotating combination 140 shown in FIGS. 2, 14, and 15. In the following second embodiment, descriptions of parts common to the first embodiment are omitted.

  As shown in FIG. 2, the rotating combination 140 is provided on the left side of the game area 8 and at a substantially central portion in the vertical direction. As shown in FIGS. 14 and 15, the rotating accessory 140 includes a decorative body (movable body) 141, a stepping motor 142, and an index detection sensor (movable body detection means) 150. The stepping motor 142 includes a motor main body 143 that is fixed to the back surface of the game board 5 via a bracket (not shown), and a motor shaft 144 that protrudes to the left from a substantially central portion of the motor main body 143.

  The decorative body 141 includes a cylindrical portion 145, a side surface portion 146, an index 147, and a motor bearing hole forming portion 148, which are integrally formed. The cylinder portion 145 is a large-diameter cylindrical body extending in the left-right direction. On the outer peripheral surface of the cylindrical portion 145, a character string “CHANCE” is written side by side in a direction orthogonal to the rotation direction of the decorative body 141. A part of the cylindrical portion 145 is exposed from a substantially rectangular display window 8a provided on the left side of the game area 8 and at a substantially central portion in the vertical direction, and is visible to the player. The side surface portion 146 is a disk-like body that extends inward from the inner edge of the left end of the outer cylinder portion 145. The index 147 is a protruding piece that extends rightward from the inner surface 146a of the side surface portion 146 inside the tube portion 145 and has a predetermined width in the rotation direction. The motor bearing hole forming portion 148 is a columnar body extending rightward from a substantially central portion of the inner surface 146a of the side surface portion 146. The motor bearing hole forming portion 148 has a motor bearing hole 148a inside. When the motor shaft portion 144 is inserted into the motor bearing hole 148a, the decorative body 141 is rotatably supported on the back surface of the game board 5 via the stepping motor 142. The index 147 is a position where the character string notation part (character string notation part) on the outer peripheral surface of the outer cylinder part 145 is not exposed through the display window 8a, for example, the character string notation part is the lower end of the outer cylinder part 145. It is formed so as to be positioned at the uppermost position in the rotational position of the decorative body 141 when positioned at the portion. When the decorative body 141 rotates, the position of the index 147 changes. Note that the downward arrow in FIG. 14 indicates the direction of rotation of the decorative body 141 that rotates following the rotation of the stepping motor 142.

  As shown in FIG. 15, the index detection sensor 150 includes a photo interrupter including a light emitting unit 151 and a light receiving unit 152. The index detection sensor 150 is fixed to the back surface of the game board 5 via a bracket 153. The light emitting unit 151 and the light receiving unit 152 of the index detection sensor 150 are configured such that the index 147 receives light from the light emitting unit 151 when the rotational position of the decorative body 141 is within a predetermined range including when the index 147 is positioned at the top. It arrange | positions so that it may interpose between the parts 152. The index detection sensor 150 transmits an index detection signal to the sub-control device 72 when the index 147 is interposed between the light emitting unit 151 and the light receiving unit 152. In the present embodiment, the rotation position of the decorative body 141 when the stepping motor 142 is reversed by the effect control CPU 92 and the index detection sensor 150 starts detecting the index 147 is set as the first position.

  The ROM 93 of the sub-control device 72 in this embodiment stores 48 steps as the basic step number. The ROM 93 stores 200 steps (the number of steps corresponding to one rotation of the decorative body 141) as the number of additional steps.

  The effect control CPU 92 of the sub control device 72 in the present embodiment executes the effect control (drive control of the rotating character 140) by the rotating character 140 based on the variation pattern command transmitted from the main control CPU 73. The drive control of the rotating combination 140 includes effect processing and index detection processing. The index detection process includes a push-in process.

  In the effect process, the effect control CPU 92 selects one effect pattern from a plurality of effect patterns stored in the ROM 93 on the basis of the variation pattern command transmitted from the main control CPU 73, and the predetermined control is performed according to the selected effect pattern. A pulse signal is output to the stepping motor 142 in accordance with the excitation pattern for reversing the rotation, the driving of the stepping motor 142 is controlled, the stepping motor 142 is reversed, and the ornamental body 141 at the origin position described later is rotated. For example, the effect pattern selected based on the variation pattern command transmitted from the main control CPU 73 rotates the decorative body 141 to expose the character string “CHANCE” written on the outer peripheral surface from the display window and stops. In the case of the content, the stepping motor 142 is reversed by the number of steps of 150 steps (corresponding to 3/4 rotation of the decorative body 141), and the decorative body 141 is rotated about 3/4 to expose the character string from the display window 8a. Then, the driving of the stepping motor 142 is stopped, and the decorative body 141 is stopped at this rotational position. In the present embodiment, this rotational position is the second position. In the present embodiment, the effect control CPU 92 stops the decorative body 141 at the second position at the end of the effect process, regardless of which effect pattern is selected.

  The effect control CPU 92 executes an index detection process after the effect process ends, and returns the decorative body 141 from the second position to the first position. In the index detection process, the effect control CPU 92 selectively executes an index detection process with a margin and an index detection process without a margin.

  In the index detection process with a margin, the effect control CPU 92 outputs a pulse signal that reversely rotates the stepping motor 142 to reversely rotate the stepping motor 142 and rotate the decorative body 141. The effect control CPU 92 counts the number of pulses of the output pulse signal as the number of driving steps of the stepping motor 142. Specifically, the effect control CPU 92 adds 1 to the count value stored in the count value storage area of the RAM 94 and stores it every time one pulse signal is output. Further, every time one pulse signal is output, it is determined whether or not the index detection sensor 150 has detected the index 147 based on whether or not the index detection signal has been received. If an index detection signal is received, it is determined that it has been detected, and a push-in process is executed. On the other hand, when the index detection signal has not been received, it is determined that the index detection signal has not been detected, and the count value (count step number) stored in the RAM 94 is the number of steps obtained by adding the additional step number to the basic step number. It is determined whether or not the number of drive steps has been exceeded. If not, the output of a pulse signal for reversing the stepping motor 142 is repeated. On the other hand, if it exceeds, the index error flag is set to ON and the push-in process is executed.

  In the marginless index detection process, the effect control CPU 92 outputs a pulse signal that reversely rotates the stepping motor 142 to reversely rotate the stepping motor 142 and rotate the decorative body 141. The effect control CPU 92 counts the number of pulses of the output pulse signal as the number of driving steps of the stepping motor 142. Specifically, the effect control CPU 92 adds 1 to the count value stored in the count value storage area of the RAM 94 and stores it every time one pulse signal is output. Further, every time a pulse signal is output, it is determined whether or not the count value (count step number) stored in the RAM 94 exceeds the basic step number. If not, the pulse signal output is repeated. . On the other hand, if it has exceeded, push-in processing is executed.

  In the pushing process, the effect control CPU 92 outputs a pulse signal that reverses the stepping motor 142 by a predetermined number of pushing steps, that is, two steps in this embodiment (that is, a two-pulse pulse signal according to the excitation pattern for reverse rotation), Thereafter, the driving of the stepping motor 142 is stopped, and the decorative body 141 is stopped at this rotational position (origin position).

  In the present embodiment, when the index detection sensor 150 enters an index error state in which the index 147 cannot be detected due to, for example, a short circuit of the chip capacitor, the drive control of the first rotating accessory 140 after this state is reached. Since the index detection process with margin is selectively executed in the index detection process, the effect control CPU 92 drives the stepping motor 142 for 248 steps of the normal drive step number (the number of basic steps plus the number of additional steps). After that, the push-in process is executed. Therefore, even if the rotation position of the decorative body 141 reaches the first position before the effect control CPU 92 finishes driving the stepping motor 142 for the normal drive step number, the effect control CPU 92 is equivalent to the normal drive step number. Since the stepping motor 142 is driven until the driving is completed, the decorative body 141 is rotated by about one rotation (about 200 steps) (when this occurs at every driving control, the player rotates extra. There is a possibility that the decorative body 141 may feel uncomfortable). However, in this index detection process with a margin, the effect control CPU 92 sets the index error flag of the RAM 94 to ON, so in the index detection process in the drive control of the rotating accessory 140 performed by the effect control CPU 92 on and after the next time, the margin None Index detection processing is selectively executed. In the marginless index detection process, the effect control CPU 92 executes the push-in process without reversing the stepping motor 142 by the number of basic steps and then reversing the number of additional steps. Therefore, in the index detection process after the next time, the decorative body 141 is not rotated by about one extra turn (about 200 steps), so that the player can be prevented from feeling uncomfortable.
