  Therefore, the first annular portion 109 is supported by a plurality of arm portions 108 extending from the base portion 107, and the second annular portion 110 is formed by the bridge portion 111 formed on the first annular portion 109. The first and second annular portions 109 and 110 are supported by each other at a constant interval (substantially the same interval as the width WT of the reel tape MTP1). Then, the reel tape MTP1 formed of a long plastic sheet on which a plurality of symbols shown in FIG. 8 are printed is mounted on the outer periphery of the first and second annular portions 109 and 110, An outer peripheral surface of the main reel MR1 is formed.

  Further, a female screw portion 104a is formed at the center of the rotating shaft 104, and through holes 105b and 107a aligned with the female screw portion 104a are also formed at the central portions of the relay shaft 105 and the base 107, respectively. The relay shaft 105, the relay member 106, and the base 107 are fixed to the rotating shaft 104 of the stepping motor MM1 by screwing and tightening the male screw 112 to the female screw portion 104a through the through holes 107a and 105b. Thus, the main reel MR1 is rotated by receiving the driving force of the stepping motor MM1.

  Although not shown, the stepping motor MM1 incorporates an optical rotary encoder that detects the rotation angle of the rotation shaft 104 with respect to a predetermined reference angle. By controlling the stepping motor MM1 while comparing the angle detection signal output from the control signal supplied from the main control board 700, the rotation of the stepping motor MM1 is controlled according to the control signal supplied from the main control board 700. Control of braking and stopping is performed, and accordingly, rotation of the main reel MR1 and control of braking and stopping are appropriately performed.

  Thus, the main reel MR1 has a cylindrical shape and is reduced in weight by mounting the reel tape MTP1 on a skeleton formed of lightweight plastic, and gives a large load to the stepping motor MM1. There is no such thing.

  Further, when the base 107 is fixed to the rotating shaft 104, the main reel MR1 is disposed so as to contain the stepping motor MM1, so that a unit structure having a small thickness in the axial direction of the rotating shaft 104 is realized.

  The second main reel unit having the main reel MR2 and the stepping motor MM2 assembled to the support plate MS2, and the third main reel unit having the main reel MR3 and the stepping motor MM3 assembled to the support plate MS3 are also described above. It has the same basic structure as the first main reel unit, and the reel tape MTP2 shown in FIG. 8 is mounted on the main reel MR2, and the reel tape MTP3 is mounted on the main reel MR3. The widths of the reel tapes MTP2 and MTP3 are also equal to the width WT of the reel tape MTP1.

  In addition, as shown in FIG. 8, the reel tapes MTP1, MTP2, and MTP3 are combined with five kinds of symbols of “watermelon”, “grape”, “lemon”, “peach”, and “eggplant”, respectively. It is drawn one by one.

The main reel device 100 is preferably formed with the specifications listed below.

[9] The pitch interval of the pattern is PP = 29.5 mm.
[10] Length of reel tapes MTP1 to MTP3 is L = 383mm and width is WT = 44mm
However, the number of control steps per rotation of the stepping motors MM1 to MM3 is 400 steps, and the rotation angle per symbol is controlled in 30 steps or 31 steps.

  The above specifications are based on conditions that do not impair as much as possible the gameability (or winning pattern, etc.) of a slot machine that aligns symbols using a large main reel mounted on a conventional and well-known slot machine. Is the most suitable design specification planned in consideration of controllability, visibility and the like.

However, the above-described transparent window WD2 is defined by the sealing member SEL interposed between the substrates SB1 and SB2, and the liquid crystal LQ is filled in the area inside the transparent window WD2 defined by the sealing member SEL. Not. Further, the reflection plate RFM is provided only in a region excluding the transparent window WD2 on the back surface of the transparent plate TPB. For these reasons, the area where the transparent window WD2 of the liquid crystal display panel LCD is formed is a non-display area where the light transmittance is high and no video is displayed.

  Although not shown, the liquid crystal display panel LCD is connected to a display control board DCNT that performs control for displaying an image on the liquid crystal display LQD, a liquid crystal display LQD, and the display control board DCNT. A flexible board on which a driving LSI for driving the LQD is mounted is unitized.

  The light emitted from the backlight LMP to the side surface of the transparent plate TPB is transmitted through the transparent plate TPB, and a part thereof is diffusely reflected by the reflection plate RFM provided on the back surface of the transparent plate TPB and supplied to the liquid crystal display LQD side. Therefore, the transmission image (video) displayed on the liquid crystal display LQD is displayed brightly when viewed from the player side.

  Each of the sub reels SR1, SR2, SR3 is designed to have a diameter of about 230 mm and a width of about 80 mm. The outer reels SR11, SR21, SR31 are arranged on the outer reels on the main reels MR1, MR2, MR3. Also displays 21 large symbols.

  11 and 12 again, the outer reel SR31 and the inner reel SR32 are rotated by the rotational force output from the stepping motors SM31 and SM32 via the transmission means 250. That is, the stepping motors SM31 and SM32 are attached to the transmission unit 250, and the end of the shaft 251 to which the rotational force of the stepping motor SM31 is applied via the reduction mechanism incorporated in the transmission unit 250 is the outer reel. The shaft 251 and the base 211a of the outer reel SR31 are fixed by being fitted into a shaft hole provided in the base 211a of the SR31 and tightening a set screw 261 or the like. Further, the end of the tubular shaft 252 to which the rotational force of the stepping motor SM32 is applied via the speed reduction mechanism in the transmission means 250 is inserted into the shaft hole provided in the base 212a of the inner reel SR31, and the tip of the tubular shaft 252 The tubular shaft 252 and the base 212a of the inner reel SR32 are fixed to each other by tightening the nut 262 into the threaded portion screwed into the portion. The tubular shaft 252 has a through-hole formed along the rotation center axis, and the shaft 251 is inserted into the through-hole so that the shafts can rotate independently without contacting each other.

  The transmission means 250 is fixed to the brackets 281 and 282, which are provided on the inner side of the unit substrate 280, on the side where the stepping motors SM31 and SM32 are attached, via an attachment portion that protrudes from the periphery of the gear case.

A plastic cover 294 is attached to the fixture 293 with the substrate 291 interposed therebetween.

  In the sub reel device 200 having such a configuration, the drive circuit board 600 supplies a drive pulse signal obtained by performing pulse width control to each stepping motor in accordance with a control signal supplied from the main control board 700 as the game progresses. Thus, by causing each stepping motor to rotate forward, reverse, and stop, the movement of each sub-reel SR1, SR2, SR3 is changed variously, and the display is changed by changing the design accordingly.

  For example, in the third sub-reel unit, when a driving pulse signal is supplied to the stepping motor SM31, the rotational force output from the stepping motor SM31 is transmitted to the outer reel SR31 via the shaft 251 provided in the transmission means 250. The Then, the outer reel SR31 rotates at a rotation speed corresponding to the frequency of the drive pulse signal.

  The outer reel SR31 is provided with a light shielding piece 211f, and the light shielding piece 211f passes through the sensing portion of the reference position sensor 231 every time the outer reel SR31 rotates once. When the reference position sensor 231 is shielded by the light shielding piece 211f, the reference position sensor 231 is turned on, and a detection signal indicating that the outer reel SR31 is at a specific rotation angle, that is, the reference position is output to the drive circuit board 600. . The drive circuit board 600 compares the detection signal of the reference position with the number of pulses of the drive pulse signal output to the stepping motor SM31, and controls rotation, braking, and stop while grasping the rotation angle of the outer reel SM31. Is to be done properly.

  Similarly, when a drive pulse signal is supplied from the drive circuit board 600 to the stepping motor SM32, the rotational force output from the stepping motor SM32 is transmitted to the inner reel SR32 via the tubular shaft 252 of the transmission means 250. As a result, the inner reel SR32 rotates at a rotation speed corresponding to the frequency of the supplied drive pulse signal.

  The reference position sensor 232 detects the reference position of the inner reel SR32 by the light shielding piece 212f formed on the inner reel SR32 shielding the sensing unit, and outputs this detection signal to the drive circuit board 600. The drive circuit board 600 appropriately controls the rotation, braking, and stop of the inner reel SM32 by comparing the detection signal of the reference position of the inner reel SR32 with the drive pulse signal.

  In this way, the symbols and patterns drawn on the outer peripheral surface of the sub reels SR1, SR2, SR3 having a double reel structure are displayed in an overlapping manner, thereby decorating the symbols of the sub reels SR1, SR2, SR3 in various display forms. Can be displayed. Further, the light emitting diodes 292 arranged inside the inner reels SR12, SR22, SR32 irradiate light from the inner side of the inner reels SR12, SR22, SR32 toward the display surface side, whereby the inner reels SR12, SR22, SR32 are irradiated. In addition, the symbols and color patterns drawn on the outer peripheral surfaces of the outer reels SR11, SR12, SR12 can be displayed brightly on the display surface side.

In other words, the small role <2> wins only by aligning the “peach” symbol of the main reel MR1 on the effective line L1 of the transparent window WD1, and the symbol 3 of the remaining main reels MR2 and MR3 is 3 It is a role that pays game medals of three (3 times the number of bets).

  When the player turns on the bet button BT1 (or BT2) to present the number of bets per game and turns on the start lever BL, the main control board 700 starts control of one game and performs a lottery drawing. Do.

  In this role lottery, first, the microprocessor MPU in the main control board 700 performs random number calculation, whereby 1 within the range of the minimum random number value 0 to the maximum random number value ηmax (65535 in this embodiment). Two random values ηi are generated internally.

  Then, as shown in FIG. 16B, the single bonus (SB), the replay, the small combination <1>, and the small combination <2> have a predetermined random number value from the minimum random value 0 to the maximum random value ηmax. The microprocessor MPU is assigned in advance in association with the range, and the microprocessor MPU determines the coincidence by comparing the internally generated random number value ηi with each of the assigned random number ranges. One of the bonus (SB), replay, small role <1>, and small role <2> is drawn. If the internally generated random value ηi does not correspond to any of the random values of single bonus (SB), replay, small role <1>, and small role <2>, the microprocessor MPU Lottery.

  For example, the microprocessor MPU draws the small role <2> when the internally generated random value ηi satisfies the relationship 0 ≦ ηi <η1 shown in FIG. 16B, and satisfies the relationship η1 ≦ ηi <η2. If a relationship of η2 ≦ ηi <η3 is satisfied, a replay (replaying player) is selected, and if a relationship of η3 ≦ ηi <η4 is satisfied, a single bonus (SB) is selected, and η4 ≦ When the relationship of ηi <ηmax is satisfied, other combinations or loses are drawn.

  The range of random values corresponding to the loss is the largest, and then the range of random values gradually decreases in the order of small role <2>, small role <1>, replay (replaying role), and single bonus (SB). By being determined in advance, the lottery probability of losing is the highest, and the lottery probability of the single bonus (SB) is the lowest.

  Further, the main control board 700 performs the role lottery, commands the spinning device board 900 to rotate the main reels MR1, MR2, MR3 at a predetermined speed of 80 rpm or less, and further instructs the sub control board 300 to execute the sub reels. Rotating SR1, SR2 and SR3, displaying effect images on the liquid crystal display panel LCD, and further driving the effect lamps 13a to 13e, 14b, 14c, 15b and 15c and the speakers Q1 to Q4 Start production to appeal to.

  Next, when the player performs stop operations on the stop buttons BP1, BP2, BP3 in an arbitrary order, the main control board 700 instructs the spinning device board 900 to stop the main reels MR1, MR2, MR3 as described above. In addition, the sub-control board 300 is instructed to change the rotation of the sub-reels SR1, SR2, SR3, and the images displayed on the liquid crystal display panel LCD and the effect lamps 13a to 13e, 14b, 14c, 15b. , 15c are turned on or blinked, and the sound effects of the speakers Q1 to Q4 are changed to produce an appealing visual and auditory response corresponding to the stop operation of the player.

  Here, when the main control board 700 has drawn the single bonus (SB) in the above-mentioned role lottery, the spinning device board 900 is drawn on the outer peripheral surface of each main reel MR1, MR2, MR3. Stepping motors MM1, MM2, and MM3 are braked and controlled in the order in which they were stopped in order to align the designs on the effective line L1 of the transparent window WD1 with a combination of "watermelon"-"peach"-"peach". Stop within time τ (ie, 190 msec).

  That is, the spinning device substrate 900 satisfies the condition of the number of control frames Nz within the stop time τ, and the symbols drawn on the outer peripheral surfaces of the main reels MR1, MR2, MR3 are “watermelon”-“peach”. ”-“ Peach ”is combined to stop on the effective line L1.

  Here, when the main reel MR1 is rotating, for example, the “grape” symbol (designated by t1) drawn at the bottom of the reel tape MTP1 shown in FIG. 8 is the effective line of the transparent window WD1. If the player stops the stop button BP1 when positioned on L1, the spinning device substrate 900 has the control reel number Nz set to 3 (Nz ≦ 3), so the main reel MR1 Is rotated by up to three frames, and when the “watermelon” symbol of the main reel MR1 is positioned on the effective line L1 during the rotation, the stepping motor MM1 and the main reel MR1 are stopped at that time. That is, when the “watermelon” symbol indicated by the reference symbol t2 in FIG. 8 is positioned on the effective line L1, the stepping motor MM1 and the main reel MR1 are stopped at that time, which corresponds to the winning combination. The "watermelon" symbol to be stopped is accurately stopped on the effective line L1.

  Further, when the main reel MR1 is rotating and, for example, the “watermelon” symbol indicated by reference numeral t2 in FIG. 8 is positioned on the effective line L1 of the transparent window WD1, the player performs a stop operation on the stop button BP1. If so, the spinning device substrate 900 stops the main reel MR1 at the time t2 when the stop operation is performed. Further, when the symbol “watermelon” indicated by t2 is almost separated from the effective line L1 of the transparent window WD1, the number of control frames Nz is set to 3 (Nz ≦ 3). The lottery is performed by rotating the main reel MR1 by a maximum of three frames and stopping the stepping motor MM1 and the main reel MR1 when the “watermelon” symbol indicated by the symbol t3 is positioned on the effective line L1. The symbol of “watermelon” corresponding to the played role is accurately stopped on the effective line L1.

  Similarly, since the spinning device substrate 900 has the control frame number Nz set to 3 (Nz ≦ 3), the main reel MR1 is rotated by up to 3 frames from the time when the stop operation is performed, and the rotation is performed. When the “watermelon” symbol of the main reel MR1 is positioned on the effective line L1, the stepping motor MM1 and the main reel MR1 are stopped at that time, so that the single bonus (SB) that is drawn in a lottery is almost certainly obtained. The corresponding “watermelon” symbol is positioned on the effective line L1, and the stepping motor MM1 and the main reel MR1 are stopped.

  Further, even if any of the other small roles <1>, small roles <2>, and replays (replays) is drawn, the spinning device substrate 900 is the same as in the case of the single bonus (SB) role. By controlling the stepping motor MM1 while satisfying the conditions of the number of control frames Nz and the stop time τ, it is almost certain that the symbols corresponding to those roles (when the lottery role is a small role <1>) "Watermelon", "peach" in the case of the small role <2>, "grape" in the case of replay) is positioned on the effective line L1, and the stepping motor MM1 and the main reel MR1 are stopped.

  Further, when the stop buttons BP2 and BP3 are operated to stop, the spinning device substrate 900 satisfies the conditions of the number of control frames Nz and the stop time τ as in the case where the stop button BP1 is operated. However, by controlling the stepping motors MM2 and MM3 for braking, the symbol corresponding to the winning combination is positioned on the effective line L1, and the stepping motors MM2 and MM3 and the main reels MR2 and MR3 are stopped. Let

  The main control board 700 stops when the three symbols of the main reels MR1, MR2 and MR3 are aligned on the effective line L1 in a combination corresponding to the lottery combination as shown in FIG. When it is determined that the winning is confirmed, the power supply device substrate 500 is instructed to pay out a predetermined number of game medals.

  In addition, the main control board 700 instructs the sub control board 300 to cause the effect display device to perform an effect for notifying the winning determination. FIG. 17 shows an example of display by the effect display device. For example, when the single bonus (SB) is won in the above-mentioned role lottery, and the stop buttons BP1, BP2, BP3 are operated, the symbols on the main reels MR1, MR2, MR3 are “watermelon”-“peach”-“peach”. When the combination stops, the sub control board 300 displays symbols similar to the symbols related to winning on the sub reels SR1, SR2, SR3 as shown in FIG. Then, an image of “fireworks” is displayed in the display area of the liquid crystal display panel LCD around the transparent window DW2, and an effect display for notifying that the winning of the single bonus (SB) is confirmed is performed.

  In addition, in the display area of the liquid crystal display panel LCD, numerical information such as the number of credits (for example, the number “35”), the number of acquired medals (for example, a picture of “13 medals”), and characters for giving a prize Information (for example, characters “WIN”) and the like are displayed. It should be noted that the above-described effect display is an example, and it goes without saying that the effect display may be performed while the main reels MR1, MR2, MR3 are rotating.
