Further, a demultiplexer 419 is connected to the output interface 470. The demultiplexer 419 distributes the signal transmitted from the output interface 470 to each display unit and the like. That is, the demultiplexer 419 determines the upper lamp 150, the side lamp 151, the center lamp 152, the waist lamp 153, the lower lamp 154, the reel panel lamp 128, the title panel lamp 170, and the payout exit strobe 171 according to the data received from the CPU 410. To control. The title panel lamp 170 is a lamp that illuminates the title panel 162, and the payout exit strobe 171 is a strobe type lamp installed inside the medal payout opening 155. The CPU 410 performs signal transmission to the door / liquid crystal screen control unit 490 via the demultiplexer 419. The door / liquid crystal screen control unit 490 is a control unit that controls the liquid crystal display device 157 and the door device 163.

<Main control unit main processing>
Next, the main process of the main control unit 300 will be described with reference to FIG. FIG. 3 is a flowchart showing the flow of main processing of the main control unit 300.

  Basic control of the game is performed mainly by the Main CPU 310 of the main control unit 300, and unless the power supply is detected, the main CPU 310 repeatedly executes the main control unit main process of FIG. Become.

  When power is turned on to the slot machine 100, first, various initialization processes are executed. Thereafter, in step S101 of the main control unit main process, a process related to medal insertion is performed. Here, it is checked whether or not medals have been inserted, and the winning line display lamp 120 is turned on according to the number of medals inserted.

  In step S102, a process related to a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated. If it is determined that the start operation has been performed, the number of inserted medals is determined.

  In step S103, a valid pay line 114 is determined. In step S104, the random number generated by the random number generator 317 is acquired. In step S105, the winning combination internal lottery is performed using the random value acquired in step S104 and the winning combination lottery table stored in the ROM 312.

  In step S106, one of the reel stop control tables is selected with reference to the stop position data selection table based on the result of the internal lottery in step S105. In step S107, rotation of all reels 110 to 112 is started by reel rotation start processing.

  In step S108, the reels 110 to 112 corresponding to the pressed stop buttons 137 to 139 are stopped from rotating by the reel stop control process. At this time, the reels 110 to 112 are stopped based on the reel stop control table selected in step S106.

  In step S109, the winning determination of the symbols stopped when the stop buttons 137 to 139 are pressed is performed. Here, it is determined that the winning combination is won when the winning winning combination 114 corresponding to the internal winning winning combination or the winning combination having the flag carried over is arranged (displayed). . For example, if “Replay-Replay-Replay” is arranged on the validated winning line 114, it is determined that the player wins the replay.

  In step S110, a medal payout process is performed. In this medal payout process, if a winning combination with a payout is won, the number of medals corresponding to the winning combination is paid out. In step S111, game state control processing is performed. In this gaming state control process, control for shifting the gaming state is performed.

<Operation principle of drive motor>
Next, the operation principle of the drive motor 616 that is the drive source of the reels 110 to 112 will be described in detail with reference to FIG. The figure schematically shows the operation principle of the drive motor 616.

  The drive motor 616 includes a stator 616A made of a fixed electromagnet, and a rotor 616B rotatably attached to a rotating shaft (not shown). A current is passed through a coil wound around the stator 616A to cause each phase of the stator 616A. Are sequentially magnetized based on an excitation pattern described later, and the rotor 616B is rotated by attracting the rotor 616B with a magnetic force.

  As described above, in this embodiment, the drive motor 616 is a 1-2 phase excitation stepping motor. The stator 616A of the 1-2 phase excitation type stepping motor has four phases of A phase, B phase, / A phase, and / B phase, and these four phases are excitation patterns as shown in FIG. A phase (1 phase excitation) → A phase and B phase (2 phase excitation) → B phase (1 phase excitation) → / A phase and B phase (2 phase excitation) → / A phase (1 phase excitation) → / A By exciting in the order of phase and / B phase (2-phase excitation) → / B phase (1 phase excitation) → A phase and / B phase (2 phase excitation) → A phase (1 phase excitation) → The rotor 616B is configured to rotate. In the figure, for convenience of explanation, the number of each phase arranged in the stator 616A is two, but it is not limited to this example.

  More specifically, the CPU 310 of the main control unit 300 uses the above-described output interface 370 and the reel motor control unit 330 to turn on a pulse signal (for example, a high level) in the phase for exciting the stator 616A of the drive motor 616. At the same time as outputting a level signal), an off-level pulse signal (for example, a low-level signal) is output to a phase where excitation is not performed, thereby exciting a predetermined phase. As a result, the rotor 616B of the drive motor 616 is rotated by a predetermined angle (one step). For example, the CPU 310 of the main control unit 300 outputs an on-level pulse signal (for example, a high-level signal) to the A phase of the stator 616A of the drive motor 616, and at the same time turns off to the B phase, / A phase, and / B phase. By outputting a level pulse signal (for example, a low level signal), only the A phase is excited, the rotor 616B is rotated by one pulse (one step), and thereafter the excitation is switched in the above order. The rotor 616B is rotated by a predetermined pulse. In addition, A phase (1 phase excitation) → A phase and B phase (2 phase excitation) → B phase (1 phase excitation) → / A phase and B phase (2 phase excitation) → / A phase ( 1 phase excitation) → / A phase and / B phase (2 phase excitation) → / B phase (1 phase excitation) → A phase and / B phase (2 phase excitation) for 8 pulses (8 steps) Hereinafter, it may be referred to as one cycle.

  Here, in the present embodiment, the number of pulses required to rotate the rotor 616B once (360 degrees) is set to 504 pulses (63 cycles). Therefore, the rotation angle of the rotor 616B per pulse is about 0.71428 degrees (= 360 degrees / 504 pulses). In addition, since the number of pulses necessary to rotate the rotor 616B by 90 degrees is 15 cycles and 6 pulses (= 504 pulses × 90 degrees / 360 degrees / 8 pulses), the first reel frame 612 with respect to the movable body gear 620 When the circumferential engagement position is shifted by 90 degrees, the position of the rotor 616B with respect to the first reel frame 612 is shifted by 6 pulses before and after the rotation of the first reel frame 612. Further, since the number of pulses necessary for rotating the rotor 616B by 180 degrees is 31 cycles and 4 pulses (= 504 pulses × 180 degrees / 360 degrees / 8 pulses), the first reel frame 612 with respect to the movable body gear 620 When the circumferential engagement position is shifted by 180 degrees, the position of the rotor 616B with respect to the first reel frame 612 is shifted by 4 pulses before and after the rotation of the first reel frame 612.

  As a comparative example, considering the case where the number of pulses required to rotate the rotor 616B once (360 degrees) is set to 400 pulses (63 cycles), the rotation angle of the rotor 616B per pulse is 0. .9 degrees (= 360 degrees / 400 pulses). In this case, since the number of pulses necessary for rotating the rotor 616B by 90 degrees is 12 cycles and 4 pulses (= 400 pulses × 90 degrees / 360 degrees / 8 pulses), the first reel for the movable body gear 620 is used. When the circumferential engagement position of the frame 612 is shifted by 90 degrees, the position of the rotor 616B with respect to the first reel frame 612 is shifted by 4 pulses before and after the rotation of the first reel frame 612. Further, since the number of pulses necessary for rotating the rotor 616B by 45 degrees is 6 cycles and 2 pulses (= 400 pulses × 45 degrees / 360 degrees / 8 pulses), the first reel frame 612 with respect to the movable body gear 620 When the circumferential engagement position is shifted by 45 degrees, the position of the rotor 616B with respect to the first reel frame 612 is shifted by two pulses before and after the rotation of the first reel frame 612. Further, since the number of pulses necessary for rotating the rotor 616B by 135 degrees is 18 cycles and 6 pulses (= 400 pulses × 135 degrees / 360 degrees / 8 pulses), the first reel frame 612 with respect to the movable body gear 620 When the circumferential engagement position is shifted by 135 degrees, the position of the rotor 616B with respect to the first reel frame 612 is shifted by 6 pulses before and after the rotation of the first reel frame 612.

  On the other hand, since the number of pulses required to rotate the rotor 616B by 180 degrees is 25 cycles (= 400 pulses × 180 degrees / 360 degrees / 8 pulses), the circumferential direction of the first reel frame 612 with respect to the movable body gear 620 When the engagement position is shifted by 180 degrees, the position of the rotor 616B with respect to the first reel frame 612 is the same before and after the rotation of the first reel frame 612, and adjusting the position of the rotor 616B with respect to the first reel frame 612 is not possible. Can not.

<Reel inspection device>
Next, the reel inspection apparatus 700 will be described with reference to FIG. This figure is an external perspective view showing a state in which the reel drive unit 602 is set in the reel inspection apparatus.

  This reel inspection apparatus 700 is a temporary installation for temporarily installing a marking member 706 that can be rotated horizontally around a rod-like member 704 standing on a base 702 and a reel drive unit 602 to be inspected. And a main body 710 that controls the reel drive unit 602 installed in the temporary installation unit 708. The main body 710 includes a start lever 710A, an emergency stop button 710B, a reset button 710C, a power-on button 710D, an OK lamp 711A, an NG lamp 711B, and an abnormal lamp 711C. The role of each button and each lamp will be described later.

  FIG. 11 is a circuit configuration diagram illustrating an example of a control circuit included in the main body unit 710. The control circuit of the main body 710 includes a CPU 712 that is an arithmetic processing unit for controlling the entire reel inspection apparatus 700, a ROM 714 for storing control programs and control data, and a RAM 716 for storing temporary data. It has. In addition, a start lever sensor 720 is connected to the CPU 712 via an input interface 718. The start lever sensor 720 is a sensor for detecting whether or not a start lever 710A provided in the main body 710 has been operated.

  Further, an inspection lamp 724 (an OK lamp 711A, an NG lamp 711B, and an abnormal lamp 711C) is connected to the CPU 710 via an output interface 722. Further, a motor control unit 728 is connected to the CPU 710 via an input / output interface 726. The motor control unit 728 is configured to be connectable to a drive motor 616 and an index sensor 606A included in the reel drive unit 602. The reel inspection device 700 controls the drive motor 616 of the reel drive unit 602 and the reel drive unit. A signal input from the index sensor 606A of 602 can be detected.

  With such a configuration, the main body unit 710 of the reel inspection apparatus 700 controls the reel drive unit 602 with the same reel control as the main control unit 300 of the slot machine 100 described above (for example, the timing of interrupt processing related to reel control, The detection timing of the light shielding piece 612D by the index sensor 606A, the control method of the drive motor 616, etc.) can be performed.

<Inspection main process>
Next, an inspection main process executed by the CPU 712 of the reel inspection apparatus 700 will be described with reference to FIG. FIG. 9 is a flowchart showing the flow of main processing of the reel inspection apparatus 700.

  The main body 710 of the reel inspection device 700 includes a counter / timer (not shown) that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 1.504 ms). As a trigger, the inspection main process is executed at a predetermined cycle.

  In step S201, it is determined whether the emergency stop button 710B is ON or OFF. If the emergency stop button 710B is ON, the process proceeds to step S202 where the drive flag is reset (information indicating that the drive flag is OFF is stored in a predetermined storage area of the RAM 716) and the emergency stop flag is set (RAM 716). The information indicating that the emergency stop flag is ON is stored in the predetermined storage area), and the process proceeds to step S203. On the other hand, if the emergency stop button 710B is OFF, the process proceeds to step S203.

  In step S203, it is determined whether the reset button 710C is ON or OFF. If the reset button 710C is ON, the process proceeds to step S204. If the reset button 710C is OFF, the process proceeds to step S205.

  In step S204, after the RAM 716 is cleared (initialized), a reset flag is set (information indicating that the reset flag is ON is stored in a predetermined storage area of the RAM 716). Note that the above-described emergency stop flag, drive stop flag, abnormality flag, OK flag, and NG flag described above are reset by clearing the RAM 716 (information indicating that each flag is OFF is stored in a predetermined storage area of the RAM 716). In addition, the previous excitation phase storage area and the current excitation phase storage area, which will be described later, are cleared.

  In step S205, it is determined whether start lever 710A is ON or OFF. When the start lever 710A is ON, the process proceeds to step S206, and when the start lever 710A is OFF, the process proceeds to step S208.

  In step S206, it is determined whether or not there is a reset flag by referring to a predetermined storage area of the RAM 716. If there is a reset flag (if set), the process proceeds to step S207, and if there is no reset flag (set) If not, the process proceeds to step S210.

  In step S207, the reset flag is cleared (information indicating that the reset flag is OFF in the predetermined storage area of the RAM 716), and then the drive flag is set (the drive flag is ON in the predetermined storage area of the RAM 716). Information is stored), and the process proceeds to step S209.

  In step S208, the predetermined storage area of the RAM 716 is referenced to determine whether or not there is a drive flag. If there is a drive flag (if set), the process proceeds to step S209, and if there is no drive flag (set). If not, the process proceeds to step S210.

  In step S209, after performing the driving process, the process proceeds to step S210. Although details will be described later, in this drive process, the drive process of the drive motor 616, reference of the excitation phase, and the like are performed under the same control as the main control unit 300 of the slot machine 100 described above.

  In step S210, referring to a predetermined storage area of the RAM 716, it is determined whether or not there is an emergency stop flag or a drive stop flag described later. If there is an emergency stop flag or a drive stop flag (when set), the process proceeds to step S211, and if there is no emergency stop flag or drive stop flag (when it is not set), the process proceeds to step S212.

  In step S211, the drive stop process is performed, and then the process proceeds to step S212. Although details will be described later, in this drive stop process, the drive motor 616 is stopped by the same control as that of the main control unit 300 of the slot machine 100 described above.

  In step S212, after performing the notification process, the process ends. Although details will be described later, in this notification process, the lighting process of the inspection lamp 724 is performed.

<Drive processing>
Next, a driving process in the above-described inspection main process will be described with reference to FIG. This figure is a flowchart showing the flow of drive processing.

  In step S301, a drive pulse is output to the drive motor 616 of the reel drive unit 602 via the motor control unit 728 based on a drive pattern including strong excitation and medium excitation described later. For example, when the drive motor 616 is started, the drive motor 616 is accelerated by strong excitation until it reaches a predetermined rotation speed (for example, 80 rpm), and then the drive motor 616 is held at a constant rotation speed by medium excitation. In addition, an on-level pulse signal (for example, a high level signal) is output to the phase in which the stator 616A of the drive motor 616 is excited, and at the same time, an off-level pulse signal (for example, a low level signal is output to the phase in which excitation is not performed). ) Is output, the excitation pattern is A phase (1 phase excitation) → A phase and B phase (2 phase excitation) → B phase (1 phase excitation) → / A phase and B phase (2 phase excitation) → / A phase (1 phase excitation) → / A phase and / B phase (2 phase excitation) → / B phase (1 phase excitation) → A phase and / B phase (2 phase excitation) → A phase (1 phase excitation) In this order, the stator 616A of the drive motor 616 is excited to rotate the rotor 616B.

  In step S302, it is determined whether or not the rotational speed of the drive motor 616 has reached a predetermined rotational speed (for example, 80 rpm). If applicable, the process proceeds to step S303, and if not, the process ends. In step S303, a signal input from the index sensor 606A of the reel drive unit 602 is monitored, and whether the light shielding piece 612D provided on the first reel frame 612 has passed between the light projecting portion and the light receiving portion of the index sensor 606A. Determine whether or not. If it is determined that the light shielding piece 612D provided on the first reel frame 612 has passed between the light projecting unit and the light receiving unit of the index sensor 606A, the process proceeds to step S304. If not, the process is performed. finish.

  In step S304, the excitation phase excited in the stator 616A of the drive motor 616 is referred to based on the passage of the light shielding piece 612D by the index sensor 606A in step S303.

  In step S305, it is determined whether or not the information on the excitation phase detected in the previous drive process is already stored in the previous excitation phase storage area provided in the RAM 716. If this is the case, in step S307, in step S304. The referenced excitation phase information is stored in the current excitation phase storage area provided in the RAM 716, and the process proceeds to step S308. Otherwise, the process proceeds to step S306.

  In step S306, the information on the excitation phase referred to in step S304 is stored in the previous excitation phase storage area, and then the process ends. In step S308, the excitation phase confirmation process described below is performed, and then the process ends.

<Excitation phase confirmation process>
Next, the excitation phase confirmation process in the above-described drive process will be described with reference to FIG. In addition, the same figure is a flowchart which shows the flow of an excitation phase confirmation process.

  In step S401, information on the respective excitation phases stored in the previous excitation phase storage area and the current excitation phase storage area is compared, and in step S402, it is determined whether or not they match. If the past two excitation phase information does not match, the process proceeds to step S403 to set an abnormality flag and then proceeds to step S407. If they match, the process proceeds to step S404. In addition, after the determination in step S402 is performed, information on the excitation phase stored in the previous excitation phase storage area and the current excitation phase storage area is cleared. As described above, by determining whether or not the information of the excitation phases for the past two times coincides, it may be possible to find a defect such as a defect of the reel drive unit 602 or a misalignment.

  In step S404, it is determined whether or not the coincident excitation phase is a specific excitation phase (excitation layer in which the drive motor 616 cannot be stopped by the excitation phase to be stopped), and if applicable, the process proceeds to step S405. After the NG flag is set in step S407, the process proceeds to step S407. If not applicable, the process proceeds to step S406. After the OK flag is set, the process proceeds to step S407. In step S407, after setting the drive stop flag, the process ends.

<Drive stop processing>
Next, the drive stop process in the above-described inspection main process will be described with reference to FIG. This figure is a flowchart showing the flow of the drive stop process.

  In step S501, it is determined whether it is time to set the initial value corresponding to the excitation phase in the counter provided in the RAM 716. If yes, the process proceeds to step S502. If not, the process proceeds to step S505.

  In step S502, an initial value corresponding to the excitation phase is set in the counter, and the process proceeds to step S503. The details will be described later with reference to FIG. 20. As shown in FIG. 20, when the excitation phases to be stopped are the A phase and the B phase (two-phase excitation), for example, the determination processing in step S402 matches. When the excitation phase is the A phase (one-phase excitation), the counter is set to 8 as the initial value of the number of pulses, and the excitation phases that coincide in the determination processing in step S402 are the / A phase and the / B phase (two phases). In the case of excitation), 3 is set in the counter as the initial value of the number of pulses.

  In step S503, excitation output of the stator 616A of the drive motor 616 is performed with medium excitation (excitation output 60%) based on the excitation phase corresponding to the counter value updated in step S504.

  In step S504, the counter value set in step S502 is subtracted. For example, if 8 is set in the counter as the initial value of the number of pulses in the previous example, the counter value is changed from 8 → 7 → 6 →... → 1 → 0 each time the processing of step S504 is executed. In this manner, the counter value is subtracted one by one until it becomes zero.

  In step S505, it is determined whether or not the value of the counter updated by subtraction in step S504 of the previous drive stop process is zero. If the count value is 0, the process proceeds to step S506. If the counter value is other than 0, the process proceeds to step S503.

  In step S506, it is determined whether or not the drive motor 616 is driven with strong excitation. If applicable, the process proceeds to step S507, and if not, the process proceeds to step S508.

  In step S507, it is determined whether or not a predetermined time (20 ms in this example) has elapsed since the drive motor 616 was driven with strong excitation. If applicable, the process proceeds to step S509, and if not, the process proceeds to step S508. move on.

  In step S508, the excitation output of the stator 616A of the drive motor 616 is strongly excited (excitation output 100%), and the drive motor 616 is stopped and held in the same excitation layer as the excitation phase that is currently excited, and then the process ends. To do.

  In step S509, the excitation output of the stator 616A of the drive motor 616 is switched from strong excitation to medium excitation, and the drive motor 616 is stopped and held in the same excitation layer as the excitation phase currently being excited, and then the process ends.

<Notification process>
Next, the notification process in the above-described inspection main process will be described with reference to FIG. This figure is a flowchart showing the flow of notification processing.

  In step S601 and step S602, it is determined whether either an abnormality flag or an emergency stop flag is set. If either the abnormal flag or the emergency stop flag is set, the process proceeds to step S603 to turn on the abnormal lamp 711C, and then the process is terminated, and either the abnormal flag or the emergency stop flag is set. If not, the process proceeds to step S604.

  In step S604, it is determined whether the OK flag is set. Then, if applicable, the process proceeds to step S605 and the OK lamp 711A is turned on, and then the process ends. If not, the process proceeds to step S606. In step S606, it is determined whether the NG flag is set. Then, if applicable, the process proceeds to step S607 to turn on the NG lamp 711B, and then the process is terminated. If not, the process is terminated.

<Assembly inspection method of reel drive unit 602>
Next, an assembly inspection method for the reel drive unit 602 will be described with reference to FIG. This figure shows the flow of the assembly inspection process of the reel drive unit 602.

  The assembly inspection process of the reel drive unit 602 includes a reel drive unit temporary attachment process ST1, an excitation phase inspection process ST2, a reel frame adjustment process ST3, a reel band application position marking process ST4, and a reel band application process ST5. Composed.

  In the reel drive unit temporary attachment step ST1, the operator attaches the first reel frame 612 of the reel drive unit 602 to the movable body gear 620 of the drive device 604, assembles the reel drive unit 602, and then mounts the reel drive unit 602. Then, it is set in the temporary installation unit 708 of the reel inspection device 700. In addition, the operator connects the drive motor 616 and the index sensor 606 </ b> A included in the reel drive unit 602 to the motor control unit 728 of the reel inspection apparatus 700.

  In the excitation phase inspection step ST2, the operator turns on the power supply button 710D of the reel inspection apparatus 700 to turn on the power of the reel inspection apparatus 700, and then presses the reset button 710C once, and then presses the start lever 710A. Turn on (press the start lever 710A) to start the excitation phase inspection. When it is determined that the reset button 710C is ON (when it is determined YES in step S203), the reel inspection apparatus 700 clears (initializes) the RAM 716, and then the start lever 710A is ON. (When it is determined YES in step S205), the motor control unit 728 drives the drive motor 616 of the reel drive unit 602 (step S301) to move the first reel frame 612 to a predetermined rotational speed. (Step S301 and Step S302).

  Subsequently, when the reel inspection apparatus 700 determines that the light shielding piece 612D provided on the first reel frame 612 has passed between the light projecting unit and the light receiving unit of the index sensor 606A (YES in step S303). When it is determined, the excitation phase excited in the stator 616A of the drive motor 616 is referred to (step S304).

  Subsequently, the reel inspection apparatus 700 compares the information on the respective excitation phases stored in the previous excitation phase storage area and the current excitation phase storage area (step S401), and determines whether or not they match. (Step S402 above). When it is determined that they do not match (when NO is determined in step S402), an abnormality flag is set (step S402), both match and the specified excitation phase is a specific excitation phase. If (YES in step S402 and YES in step S404), the NG flag is set (step S404), the two match, and the matching excitation phase is not specified. If it is not an excitation phase (YES in step S402 and NO in step S404), an OK flag is set (step S405).

  Subsequently, after the reel inspection apparatus 700 executes the above-described drive stop process to stop the rotation of the first reel frame 612, the abnormal lamp 711C is set when the abnormality flag is set in the above-described notification process. Is turned on (step S603), the OK lamp 711A is turned on when the OK flag is set (step S605), and the NG lamp 711B is turned on when the NG flag is set (step S605). S607).

  When the NG lamp 711B of the reel inspection device 700 is lit, the operator performs the reel frame adjustment process ST3 following the excitation phase inspection process ST2, and when the OK lamp 711A is lit, Subsequent to the excitation phase inspection step ST2, a reel band sticking position marking step ST4 is executed.

  In the reel frame adjustment step ST3, the operator removes the first reel frame 612 of the reel drive unit 602 from the movable body gear 618 of the drive device 604, and the first reel frame 612 is set at a predetermined angle with respect to the movable body gear 620. After rotating at 90 degrees in this example, the first reel frame 612 is attached to the movable body gear 618 again. As a result, the circumferential engagement position of the first reel frame 612 with respect to the movable body gear 620 changes by 90 degrees, so that the position of the rotor 616B with respect to the first reel frame 612 is the position of the first reel frame 612 as described above. There will be a shift of 6 pulses before and after the rotation. Thereafter, the operator executes the excitation phase inspection process ST2 again.

  In the reel band sticking position marking step ST4, the operator rotates the marking member 706 to a position close to the first reel frame 612 and puts the reel band 610 on the first reel frame 612 stopped at the reference stop position. The mark P1 which shows the start position which winds any one edge part is formed (refer Fig.18 (a)). Here, the example in which the mark P1 is formed only on the first reel frame 612 is shown, but the mark P1 is formed only on the second reel frame 614, or both the first reel frame 612 and the second reel frame 614 are formed. A mark P1 may be formed on the surface.

  In the reel band attaching step ST5, the operator winds the reel band 610 around the first reel frame 612 and the second reel frame 614 using the mark P1 formed in the reel band applying position marking step ST4 as a start position (FIG. 18 (b)), the reel drive unit assembly inspection process is completed.

<Conventional excitation phase inspection process>
Next, an excitation phase inspection process in a conventional reel inspection apparatus will be described with reference to FIG. The figure shows an example of a timing chart of an excitation phase inspection process in a conventional reel inspection apparatus.

  When the rotor 616B is stopped at the timing of exciting the stator 616A of the drive motor 616 by the shaded A phase and B phase (two-phase excitation) in the drawing, the first reel frame 612 is moved to the reference stop position (reel band 610). It is assumed that the symbol of symbol number 0 applied to can be stopped at a position where the symbol stops at the middle stage of the symbol display window 113). The excitation phase used as the stop position of the drive motor for the conventional reel is any two phases (A phase and B phase, / A phase and B phase, / A phase and / B phase, A phase and / B phase) , Any is possible).

  The control unit of the conventional reel inspection apparatus starts interrupt processing at a predetermined time interval (in this example, about 1.504 ms interval) indicated by ▼ in the figure. In this interrupt processing, the state of the index sensor 606A is detected at the timing indicated by “Idx reception timing” in the drawing, and the first reel frame 612 is provided between the light projecting portion and the light receiving portion of the index sensor 606A. When it is determined that the light shielding piece 612D has passed, the excitation phase excited in the stator 616A of the drive motor 616 is referred to. If the excitation phase referred to is one-phase excitation, it is not enough to stop the next two-phase excitation in terms of processing, so the number of pulses required to stop the next two-phase excitation is 2 Is selected, and 2 is set as an initial value of the number of pulses in a predetermined counter at the timing indicated by “initial value set” in the drawing (conventional processing corresponding to step S503). On the other hand, when the excitation phase referred to is two-phase excitation, the next two-phase excitation can be stopped in the process, so 1 is set as the number of pulses required to stop the next two-phase excitation. At the timing indicated by “Initial value output” in the figure, 1 is set as the initial value of the number of pulses in a predetermined counter (conventional processing corresponding to step S503).

  When the control unit of the reel inspection apparatus sets the next number of pulses to be output to the stator 616A in the interrupt process, a pulse corresponding to the set number of pulses is output to the stator 616A at the timing indicated by “initial value output timing” in the drawing. Is output, and excitation of the phase indicated by “excitation output” in the figure is performed.

  For example, when the excitation phase referred to at the Idx reception timing is / B phase (one-phase excitation) (when index passage is in section (2)), 2 is selected as the number of pulses, and “initial value set” in the figure is selected. "2" is set as the next number of pulses to be output to the stator 616A at the timing shown in FIG. As a result, a pulse corresponding to the set number of pulses 2 is output to the stator 616A at the timing indicated by “initial value output timing” in the figure, so that it is driven in the A phase and the / B phase (two-phase excitation) → The first reel frame 612 is moved to the reference stop position (A phase and B phase) by controlling the stator 616A in the excitation order of driving in the A phase (1 phase excitation) → stopping in the A phase and B phase (2 phase excitation). (2-phase excitation) timing). When the excitation phase referenced at the Idx reception timing is the A phase and the / B phase (two-phase excitation) (when the index passes through the section (3)), 1 is selected as the number of pulses. 1 is set as the number of next pulses to be output to the stator 616A at the timing shown in the “initial value set”. As a result, a pulse corresponding to the set number of pulses 1 is output to the stator 616A at the timing indicated by “initial value output timing” in the figure, so that driving is performed in the A phase (one-phase excitation) → A phase and B The first reel frame 612 can be stopped at the reference stop position (timing of phase A and phase B (two-phase excitation)) by controlling the stator 616A in the excitation order of stopping at the phase (two-phase excitation). .

  On the other hand, when the excitation phase referenced at the Idx reception timing is, for example, the / A phase (one-phase excitation) (when the index passes through the section (1)), 1 is selected as the number of pulses, and “ 1 is set as the number of next pulses to be output to the stator 616A at the timing shown in the “initial value set”. As a result, a pulse corresponding to the set number of pulses 1 is output to the stator 616A at the timing indicated by “initial value output timing” in the figure, so that it is driven by the / A phase and the / B phase (two-phase excitation). → Drive by / B phase (1-phase excitation) → Control the stator 616A in the excitation order of stopping at A phase and / B phase (2 phase excitation), thereby moving the first reel frame 612 to the reference stop position (A phase) And the first reel frame 612 can be stopped at the two-phase excitation position (phase A and phase B / two-phase excitation) before the reference stop position. ) Will stop. In addition, when the excitation phase referred to at the Idx reception timing is, for example, the A phase (one-phase excitation) (when the index passes through the section (4)), 2 is selected as the number of pulses, and “Initial” 2 is set as the next number of pulses to be output to the stator 616A at the timing indicated by “value set”. As a result, pulses corresponding to the set number of pulses 2 are output to the stator 616A at the timing indicated by “initial value output timing” in the figure, so that driving is performed in the A phase and the B phase (two-phase excitation) → B By driving the stator 616A in the excitation order of driving in phase (one-phase excitation) → stopping in phase A and phase B (two-phase excitation), the first reel frame 612 is moved to the reference stop position (phase A and phase B). (The timing of (2-phase excitation)), the first reel frame 612 cannot be stopped at the next two-phase excitation position (/ A phase and B phase (2-phase excitation) timing) beyond the reference stop position. Will stop at.

  Therefore, in order to stop the first reel frame 612 at the reference stop position in the excitation phase inspection process in the conventional reel inspection apparatus, it is within the range indicated by “AB stop” in the drawing (about the time corresponding to two interrupt processes). It is necessary to adjust the mounting position of the movable body gear 620 and the first reel frame 612 so that the light shielding piece 612D can be detected at 3.008 ms). In addition, if the detection error of the light shielding piece 612D due to the rotation unevenness of the drive motor (stepping motor) 616 is taken into consideration, it is within the range indicated by “inspection OK” in the drawing (about 1.504 ms which is the time for one interrupt process) ), It is necessary to adjust the mounting position of the movable body gear 620 and the first reel frame 612 so that the light shielding piece 612D can be detected. The probability that the light shielding piece 612D passes within the range indicated by “AB stop” in the figure is the range indicated by “inspection OK” in the figure (in this example, about 1.5 ms) × 4/1 cycle (this In the example, about 12 ms) = about 50%. Further, when the diameter of the first reel frame 612 is set to 250 mm, the outer circumference is 785 mm, and the pitch of the reel band 610 is about 37.4 mm (= 785 mm / 21 symbols), and three cycles are required for movement of one symbol. Since it is necessary (24 pulses / 12 steps), a deviation of 37.4 mm / 12 = 3.1 mm occurs with a deviation of one step.

<Excitation phase inspection process of this embodiment>
Next, an excitation phase inspection process in the reel inspection apparatus 700 according to this embodiment will be described with reference to FIG. The figure shows an example of a timing chart of the excitation phase inspection process in the reel inspection apparatus 700 according to the present embodiment.

  When the rotor 616B is stopped at the timing of exciting the stator 616A of the drive motor 616 by the shaded A phase and B phase (two-phase excitation) in the drawing, the first reel frame 612 is moved to the reference stop position (reel band 610). It is assumed that the symbol of symbol number 0 applied to can be stopped at a position where the symbol stops at the middle stage of the symbol display window 113). The excitation phase used as the stop position of the drive motor for the reel of this embodiment is configured to be two specific phases (in this embodiment, only the A phase and the B phase) unlike the conventional one.

  The control unit of the reel inspection apparatus 700 starts interrupt processing at a predetermined time interval (in this example, about 1.504 ms interval) indicated by ▼ in the drawing. In this interrupt processing, the state of the index sensor 606A is detected at the timing indicated by “Idx reception timing” in the drawing, and the first reel frame 612 is provided between the light projecting portion and the light receiving portion of the index sensor 606A. When it is determined that the light shielding piece 612D has passed, the excitation phase excited in the stator 616A of the drive motor 616 is referred to. Then, using the table shown in the lower right of the figure (a table in which the number of pulses (initial value) required to update the step from the currently excited phase to the specific two phases to be stopped) is updated. Select the number of pulses corresponding to the referenced excitation phase. For example, if the referenced excitation phase is / A phase and / B phase (two-phase excitation), select 3 as the number of pulses, and at the timing shown in “Initial value set” in the figure, the number of pulses in the above counter Is set to 3 as an initial value (step S503). When the excitation phase referred to is the A phase (one-phase excitation), 8 is selected as the number of pulses, and at the timing shown in “Initial value set” in the figure, the above counter is set to 8 as the initial value of the pulse number. Is set (step S503).

  When the control unit of the reel inspection apparatus sets the next number of pulses to be output to the stator 616A in the interrupt process, a pulse corresponding to the set number of pulses is output to the stator 616A at the timing indicated by “initial value output timing” in the drawing. Is output, and excitation of the phase indicated by “excitation output” in the figure is performed.

  For example, the excitation phases referred to at the Idx reception timing are the / A phase and the / B phase (two-phase excitation) (the A phase and / B phase (two-phase excitation) in which the reel cannot be stopped at the stop target) as the excitation order n. Then, when the excitation order is n-2) (when the passage of the index is the section (1)), 3 is selected as the number of pulses, and output to the stator 616A at the timing shown in the “initial value set” in the figure. 3 is set as the next number of pulses to be performed. As a result, a pulse corresponding to the set number of pulses 3 is output to the stator 616A at the timing indicated by “initial value output timing” in the figure, so that the first reel frame 612 is moved to the reference stop position (A phase and B Phase (two-phase excitation) timing). Also, if the excitation phase referred to at the Idx reception timing is / B phase (1-phase excitation) (A phase (1-phase excitation) where the reel cannot be stopped at the stop target) is the excitation order n, the excitation order is n-2. ) (When the passage of the index is in the section (2)), 2 is selected as the number of pulses, and 2 is output as the next number of pulses to be output to the stator 616A at the timing indicated by “initial value set” in the figure. Set. As a result, a pulse corresponding to the set number of pulses 2 is output to the stator 616A at the timing indicated by “initial value output timing” in the drawing, so that the first reel frame 612 is moved to the reference stop position (A phase and B phase). Phase (two-phase excitation) timing).

  In this example, the number of pulses to be output to the stator 616A is set when the excitation order is n-2 when the excitation order of the excitation phase in which the reel cannot be stopped at the stop target is n. In this example, the first reel frame 612 is stopped at the reference stop position (the shaded A-phase and B-phase (two-phase excitation) timings in FIG. 20), but the present invention is not limited to this. .

  Therefore, for example, when the excitation order of the excitation phases (for example, A phase and / B phase (2-phase excitation)) that cannot stop the reel at the stop target is n, the excitation layer (A Phase and B phase (2-phase excitation)) (when the passage of the index is in section (5)), if the number of pulses output to stator 616A is set, A phase and B phase (shaded in FIG. 20) The first reel frame 612 can be stopped at the reference stop position when the timing of the A phase and B phase (two-phase excitation) of the next cycle of the two-phase excitation) is the reference stop position. In addition, when the excitation order of the excitation phase (for example, A phase (1 phase excitation)) in which the reel cannot be stopped at the stop target is n, the excitation layer (B phase (1 phase excitation) with an excitation order of n + 2) ) (When the passage of the index is section (6)), if the number of pulses to be output to stator 616A is set, the next cycle of A phase and B phase (two-phase excitation) shaded in FIG. When the timing of the A phase and the B phase (two-phase excitation) is the reference stop position, the first reel frame 612 can be stopped at the reference stop position. Furthermore, / A phase and B phase (two-phase excitation) included in the OK region (when index passing is in section (7)) or / A phase (one-phase excitation) (index passing is in section (8)) If the number of pulses to be output to the stator 616A is set, the A phase and B phase (two phase excitation) of the next cycle of the A phase and B phase (two phase excitation) shaded in FIG. When the timing is the reference stop position, the first reel frame 612 can be stopped at the reference stop position.

  On the other hand, the excitation phase referred to at the Idx reception timing is, for example, A phase (1-phase excitation) (excitation sequence m-1) when the stop target A-phase and B-phase (2-phase excitation) are the excitation sequence m. In this case (when the passage of the index is the section (4)), 8 is selected as the number of pulses, and 8 is set as the number of the next pulse to be output to the stator 616A at the timing indicated by “initial value set” in the figure. . In this case, a pulse corresponding to the set number of pulses of 8 is output to the stator 616A at the timing indicated by “initial value output timing” in the figure. The timing of this pulse output is the first reel frame. Since the timing at which 612 can be stopped at the reference stop position (timing of A phase and B phase (two-phase excitation)) is not in time, the first reel frame 612 is moved to the reference stop position (A phase and B phase (two phase)). The first reel frame 612 stops at a position exceeding the reference stop position (next A phase and B phase (two-phase excitation) timing).

  Further, when the excitation phases referred to at the Idx reception timing are the A phase and the / B phase (two-phase excitation) (the stop target A-phase and B-phase (two-phase excitation) are the excitation order m, the excitation order is m−2. ) (When the passage of the index is the section (3)), 1 is selected as the number of pulses, and 1 is set as the number of next pulses to be output to the stator 616A at the timing indicated by “initial value set” in the drawing. Set. As a result, a pulse corresponding to the set number of pulses 1 is output to the stator 616A at the timing indicated by “initial value output timing” in the drawing, and therefore the first reel frame 612 is moved to the reference stop position (A phase and B). Phase (two-phase excitation) timing). However, since the light shielding piece 612D may vibrate due to minute vibration of the drive motor (stepping motor) 616, the behavior of the light shielding piece 612D becomes unstable, and therefore the timing at which the light shielding piece 612D passes through the index sensor 606A. There are cases where the section (3) of the OK area is entered and the section (4) of the NG area is entered. When the light shielding piece 612D passes through the index sensor 606A in the section (4) of the NG area (for example, the hatched portion in the figure), the pulse output timing causes the first reel frame 612 to move to the reference stop position as described above. Since the timing that can be stopped at (A-phase and B-phase (two-phase excitation) timing) is not in time, the first reel frame 612 is moved to the reference stop position (timing for A-phase and B-phase (two-phase excitation)). The first reel frame 612 stops at a position beyond the reference stop position (next timing of A phase and B phase (two-phase excitation)).

  Therefore, in order to stop the first reel frame 612 at the reference stop position in the excitation phase inspection step ST2 in the reel inspection apparatus 700 according to the present embodiment, the light shielding piece 612D is within the range indicated by “OK region” in the drawing. What is necessary is just to adjust the attachment position of the movable body gear 620 and the 1st reel frame 612 so that it can detect.

  For example, when the excitation phase referred to at the Idx reception timing in the excitation phase inspection process ST2 is the A phase (one-phase excitation) that is the NG region, the first of the reel drive unit 602 is set in the reel frame adjustment process ST3. The reel frame 612 is removed from the movable body gear 618 of the driving device 604, the first reel frame 612 is rotated at 90 degrees in the reel rotation direction with respect to the movable body gear 620, and then the first reel frame 612 is moved to the movable body gear 618. Attach it again. As a result, the circumferential engagement position of the first reel frame 612 with respect to the movable body gear 620 changes by 90 degrees, so that the position of the rotor 616B with respect to the first reel frame 612 is the position of the first reel frame 612 as described above. The excitation phase referred to at the Idx reception timing in the next excitation phase inspection step ST2 is an OK region that is shifted by 6 pulses from the NG region A phase (one-phase excitation). Some / B phase (1 phase excitation).

  Similarly, when the excitation phases referenced at the Idx reception timing in the excitation phase inspection process ST2 are the A phase and the / B phase (two-phase excitation) that are NG regions, the reel drive is performed in the reel frame adjustment process ST3. The first reel frame 612 of the unit 602 is removed from the movable body gear 618 of the driving device 604, and the first reel frame 612 is rotated relative to the movable body gear 620 by 90 degrees in the reel rotation direction. Is attached to the movable body gear 618 again. As a result, the circumferential engagement position of the first reel frame 612 with respect to the movable body gear 620 changes by 90 degrees, so that the position of the rotor 616B with respect to the first reel frame 612 is the position of the first reel frame 612 as described above. The excitation phase is shifted by 6 pulses before and after the rotation, and the excitation phase referred to at the Idx reception timing in the next excitation phase inspection step ST2 is shifted by 6 pulses from the NG region A phase and / B phase (2-phase excitation). The OK region is the / A phase and the / B phase (two-phase excitation).

  On the other hand, when the light shielding piece 612D is detected within the range indicated by “NG area” in the figure (in this example, the excitation phase referenced at the Idx reception timing is the A phase and the / B phase (two-phase excitation), or the excitation phase. Is the A phase (one-phase excitation), in other words, the excitation phase when the light shielding piece 612D actually passes between the light projecting portion and the light receiving portion of the index sensor 606A is the / B phase (one phase excitation). ), Or A phase and / B phase (two-phase excitation)), it is necessary to readjust the mounting positions of the movable body gear 620 and the first reel frame 612. In this case, the above-described reel frame adjustment step ST3 is executed so that the position of the rotor 616B with respect to the first reel frame 612 is shifted by at least two pulses (6 pulses in the embodiment) before and after the rotation of the first reel frame 612. For example, the mounting position of the movable body gear 620 and the first reel frame 612 can be adjusted so that the light shielding piece 612D can be detected within the range indicated by “OK region” in the drawing. Since the probability that the light shielding piece 612D passes within the range indicated by “OK region” in the figure is 6 pulses / 8 pulses = 75%, it is sufficient to perform readjustment with a probability of 25%.

  As described above, the method of assembling and inspecting the reel drive unit 602 according to the present embodiment is based on the reel band (for example, the reel band 610) on which information (for example, symbols) relating to the game is applied, and the reel band on the outer periphery. A reel frame (e.g., first reel frame 612) wound along, a light shielding piece (e.g., light shielding piece 612D) disposed on the reel frame and serving as a reference position of the reel frame, and detection of passage of the light shielding piece A reel drive for a game machine, comprising: a detection unit (for example, an index sensor 606A); and a drive device (for example, a drive device 604) that rotationally drives the reel frame using a stepping motor (for example, drive motor 616) as a drive source An assembly inspection method for a unit, wherein the reel frame is attached to the drive unit (for example, Temporary drive unit ST1) and driving the stepping motor to rotate the reel frame attached in the attachment step at a predetermined rotational speed, and the detection unit detects the passage of the light shielding piece. At the timing of receiving the identification step (for example, excitation phase inspection step ST2) for identifying the excitation phase exciting the stepping motor and one of the reel frame and the driving device based on the identification result of the identification step At least a mounting position adjusting step (for example, a reel frame adjusting step ST3) that adjusts the mounting position of the reel frame and the driving device by rotating at a predetermined angle with respect to the other. This is an assembly inspection method for a reel drive unit for a game machine.

  According to the method for assembling and inspecting the reel drive unit 602 according to the present embodiment, the motor reference position and the reel reference position are obtained by rotating one of the reel frame and the drive device at a predetermined angle with respect to the other in the attachment position adjusting step. In some cases, the deviation can be easily adjusted.

  In addition, the reel inspection apparatus 700 according to this embodiment drives the stepping motor to rotate the reel frame attached to the driving apparatus at a predetermined rotational speed (for example, a motor control unit 728 or a driving process). ) And an identification means (for example, identifying the excitation phase exciting the stepping motor at a timing when the reel unit is rotated by the rotation means and the detection unit receives the detection of the passage of the light shielding piece) Excitation phase confirmation processing) and notification means (for example, inspection lamp 724) for notifying that the excitation phase identified in the identification step is a specific excitation phase. It is an assembly inspection apparatus for a reel drive unit for a game machine.

  According to the reel inspection apparatus 700 according to the present embodiment, it is easy to determine whether or not adjustment is necessary, and it may be possible to easily adjust the deviation between the motor reference position and the reel reference position.

  The attachment position adjusting step is a step of adjusting the attachment position when the excitation phase identified in the identification step is a specific excitation phase in which the reel frame cannot be stopped at a reference stop position. May be. With such a configuration, since it is possible to determine whether or not adjustment is necessary depending on whether or not a specific excitation phase is present, it is easy to determine whether or not adjustment is necessary, and the motor reference position and reel reference are determined. In some cases, the positional deviation can be easily adjusted.

  The predetermined angle may be an angle at which the excitation phase identified in the identification step performed after the attachment position adjustment step can be changed to an excitation phase different from the specific excitation phase. With such a configuration, the adjustment can be performed at a time, and thus the man-hours necessary for the adjustment may be reduced.

  In addition, the predetermined angle is n (n is a positive integer) (for example, A phase (one-phase excitation)). In this case, the excitation phase identified in the identification step performed after the mounting position adjustment step is n-2 (for example, / B phase (one phase excitation)) or n + 2 (for example, B phase (one phase) The angle may be changed to the excitation phase that is the excitation order of excitation)). With such a configuration, the adjustment can be performed at a time, and thus the man-hours necessary for the adjustment may be reduced.

  Moreover, you may further have the winding process (for example, reel band sticking process ST5) which winds the said reel strip | belt around the said reel frame stopped after the said attachment position adjustment process. With such a configuration, it may be possible to easily confirm whether or not the adjustment is completed depending on whether or not the reel band is wound.

  In addition, after the mounting position adjusting step, a forming step for forming a mark indicating a start position for winding one end of the reel band around the stopped reel frame (for example, a reel band sticking position marking step ST4) The winding step may be a step of winding the reel band around the stopped reel frame with the mark formed in the forming step as a start position. With such a configuration, the reel band may be more reliably wound.

  The specific excitation phase is m-1 (for example, when the excitation order of excitation phases used for stopping is m (m is a positive integer) (for example, A phase and B phase (two-phase excitation)). , A phase (1 phase excitation)) and / or m−2 (for example, A phase and / B phase (2 phase excitation)) may be the excitation phase. With such a configuration, there are cases where the stepping motor can be stopped at the target position with high accuracy.

  In the above embodiment, an example of a slot machine using medals (coins) as a game medium has been shown, but the present invention is not limited to this, and for example, a game ball (for example, a pachinko ball) It can also be applied to slot machines and pachinko gaming machines that are used as media.

  In addition, the actions and effects described in the above-described embodiments are merely a list of the most preferable actions and effects resulting from the present invention, and the actions and effects according to the present invention are limited to those described in the above-described embodiments. It is not something.

  For example, in the above embodiment, the drive motor is configured by a 1-2 phase excitation type stepping motor, but a 1 phase excitation type or a 2 phase excitation type stepping motor may be applied.

  In the reel inspection apparatus according to the above embodiment, the example in which the inspection result (presence / absence of readjustment) is notified to the outside using an OK lamp or an NG lamp is shown. However, the configuration is such that the excitation phase is notified as it is. May be.

  In the reel frame adjustment step ST3, an example in which the first reel frame 612 is rotated 90 degrees in the reel rotation direction with respect to the movable body gear 620 has been described. However, the reel frame adjustment step ST3 is 90 degrees in the direction opposite to the reel rotation direction (reel (270 degrees in the rotation direction). That is, in consideration of the remainder of the number of pulses, the mounting position may be adjusted so as to shift the NG excitation phase to the OK excitation phase.

  The gaming machine reel drive unit assembly inspection method and the assembly inspection apparatus according to the present invention can be applied to inspection of a reel drive unit used in a game machine represented by a slot machine.
