A plurality of arm portions 108, a first annular portion 109 connected to the tip of the arm portion 108, a second annular portion 110 having the same diameter as the first annular portion 109, A plurality of bridge portions 111 that bridge the first annular portion 109 and the second annular portion 110 are formed.

  That is, the plurality of arm portions 108 are all formed with an equal length from the center of the base portion 107, and the circular first annular portion 109 is continuously provided at the distal end portions of these arm portions 108. Thus, the first annular portion 109 is provided concentrically from the center of the base portion 107. The plurality of bridge portions 111 provided in the first annular portion 109 are oriented in a direction perpendicular to the extending direction of the arm portion 108, and all have the same length (the width WT of the reel tape MTP1). And a second annular part 110 having the same diameter as the first annular part 109 is formed at the tip of these bridge parts 111.

  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.

  Furthermore, a female screw portion 104a is formed at the shaft center of the rotating shaft 104, and through holes 105b and 107a aligned with the female screw portion 104a are also formed at the center portions of the relay shaft 105 and the base portion 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 a reel tape MTP2 shown in FIG. 8 is mounted on the main reel MR2, and a 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.

When a symbol to be stopped is specified on the effective line L1 and a control signal is supplied, the main reel MR3 is rotated by the number of control frames Nz within the stop time τ, and the specified symbol is on the effective line L1. When they are aligned, the main reel MR3 is stopped.

  When the sub control board 300 is connected to the effect lamps 13a to 13e, 14b, 14c, 15b, and 15c and the speakers Q1 to Q4, and the control signal that suggests the start of the effect is supplied from the main control board 700, the effect is displayed. The lamps 13a to 13e, 14b, 14c, 15b, and 15c and the speakers Q1 to Q4 are driven to produce an effect appealing to the player's vision and hearing. In addition, the main control board 700 commands a lottery role, and the sub-control board 300 provides effects corresponding to the commanded role lamps 13a-13e, 14b, 14c, 15b, 15c and speakers Q1-Q4. By doing this, an effective presentation that interests the player is performed.

  Further, when the control signal suggesting the start of the production is supplied from the main control board 700, the sub control board 300 instructs the drive circuit board 600 to start the stepping motors SM1, SM2, SM3 of the sub reel device 200. The effect display is performed by rotating the sub reels SR1, SR2, SR3. Further, when a lottery role is instructed from the main control board 700, the sub control board 300 instructs the drive circuit board 600 to start the stepping motors SM1, SM2, SM3, and an effect corresponding to the instructed role. Is performed by the sub reels SR1, SR2, SR3.

  Further, when a control signal indicating start of production is supplied from the main control board 700, the sub control board 300 generates a video signal for displaying a corresponding moving image in accordance with this control signal, and outputs it to the liquid crystal display panel LCD. To do. The liquid crystal display panel LCD effects and displays a moving image (transmission video) overlapped on the sub reels SR1, SR2, SR3 based on the supplied video signal.

  The central display board 400 is connected to the bet buttons BT1 and BT2, the start lever BL and the stop buttons BP1, BP2 and BP3, and controls the output signals output from these switches BT1, BT2, BL, BP1, BP2 and BP3. It functions as a relay board that transfers to the board 700. In addition, the central display board 400 transfers an output signal output from the game medal detection sensor provided in the selection mechanism G0 to the main control board 700 to inform the medal insertion part MD of the number of medals and To inform you of the clogging and clogging.

  The main control board 700 detects the number of bets per game when the bet buttons BT1 and BT2 are turned on, and detects that a game start instruction is issued when the start lever BL is turned on. When the stop buttons BP1, BP2, BP3 are stopped in an arbitrary order, it is detected that an instruction to stop the main reels MR1, MR2, MR3 is issued in that order.

  Here, when the main control board 700 detects that the above-mentioned start lever BL is turned on, a command for lottery apparatus board 900 to rotate the above-mentioned main reels MR1, MR2, MR3 is performed after performing the role lottery. At the same time, the sub-control board 300 is commanded to cause the effect lamps 13a to 13e, 14b, 14c, 15b, and 15c, the speakers Q1 to Q4, and the sub reel device 200 to perform effects.

  When the stop buttons BP1, BP2, and BP3 are stopped in any order, the main control board 700 stops the main reels MR1, MR2, and MR3 in the order of the stop operations, and lottery is performed as described above. A command is sent to the spinning device substrate 900 to align the symbols corresponding to the roles on the effective line L1. In addition, the main control board 700 instructs the sub control board 300, and each time the stop buttons BP1, BP2, BP3 are stopped, the effect lamps 13a to 13e, 14b, 14c, 15b, 15c and the speaker Q1 are displayed. The game progress status and the like are notified to the player by variously changing the production by ~ Q4 and the sub reel device 200.

  The power supply substrate 500 is formed with a power distribution circuit that distributes various power supply voltages generated by the power supply device PWU to the hopper device HP and other parts, and supplies system power necessary for the operation of the slot machine 10 from the power distribution circuit. To do.

  When the power supply device board 500 receives a command to pay out game medals from the main control board 700, it controls the hopper device HP to pay out game medals.

  The external concentration terminal board 800 sends a signal indicating the progress of the game in the slot machine 10 output from the main control board 700 to the hall computer described above.

  Next, the operation of the slot machine 10 will be described with reference to FIG. FIG. 13 (a) relates the types of combinations provided in the slot machine 10, the combinations of symbols corresponding to each combination, the number of game medals to be paid out when winning each combination, and the like. FIG. 13B is a schematic diagram showing the principle of the role lottery.

  In FIG. 13A, the slot machine 10 includes a special combination called a single bonus (SB), a re-playing combination called replay, two small combinations, that is, a small combination <1> and a small combination <2>. Is provided.

  In the single bonus (SB), the player operates the bet button BT1 (or BT2), the start lever BL, and the stop buttons BP1, BP2, and BP3 to play one game. As a result, the main reels MR1 and MR2 shown in FIG. When the symbols drawn on the outer peripheral surface of MR3 are aligned on the effective line L1 (see FIG. 1) of the transparent window WD1 with a combination of “watermelon”-“peach”-“peach”, It is a role of providing a privilege for paying out 13 game medals (that is, 13 times the number of bets) and further allowing the player to advance the game.

  In the replay, the player operates the bet button BT2 (or BT1), the start lever BL, and the stop buttons BP1, BP2, BP3 to play one game. As a result, the outer peripheries of the main reels MR1, MR2, MR3 shown in FIG. When the symbols drawn on the surface are all aligned on the effective line L1 of the transparent window WD1 with the combination of “grape”-“grape”-“peach”, the game medals are not paid, but for the player It is a role of giving a privilege to play the game again without presenting the number of bets.

  As for the small role <1>, the player operates the bet button BT1 (or BT2), the start lever BL, and the stop buttons BP1, BP2, BP3 to play one game. As a result, the main reels MR1, MR2 shown in FIG. , When the symbols drawn on the outer peripheral surface of MR3 are stopped on the effective line L1 of the transparent window WD1 with the combination of “watermelon”-“grape”-“lemon”, the number of bets (13 times) game medal payment.

  As for the small role <2>, the player operates the bet button BT1 (or BT2), the start lever BL, and the stop buttons BP1, BP2, and BP3 to play one game. As a result, the outer periphery of the main reel MR1 shown in FIG. When the symbols of “peach” drawn on the surface stop on the active line L1 of the transparent window WD1, three game medals are paid (that is, three times the bet number). 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 BT2 (or BT1) 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. 13B, the single bonus (SB), the replay, the small combination <1>, and the small combination <2> have a predetermined random number value within the maximum random number value ηmax from the minimum random number value 0. 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 the range of each assigned random number value. 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. 13B, 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. While rotating SR1, SR2, SR3 and driving the effect lamps 13a-13e, 14b, 14c, 15b, 15c and the speakers Q1-Q4, an effect appealing to sight and hearing is started.

  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, and SR3, and the lighting lamps 13a to 13e, 14b, 14c, 15b, and 15c are turned on and blinking, and the speaker. By changing the sound effects of Q1 to Q4, an effect appealing to the sight and hearing corresponding to the stop operation of the player is performed.

  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 design 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 liquid crystal display panel LCD and the sub reel device 200 to produce an effect for notifying the winning determination. An example of effect display by these display devices will be described with reference to FIG. 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, as shown in FIG. 14A, the sub control board 300 displays the same symbol on the sub reels SR1, SR2, SR3. Then, a transmission image of “fireworks” is displayed in multiple on the liquid crystal display panel LCD, and an effect display for notifying that the winning of the single bonus (SB) is confirmed is performed.

  The effect display device may perform effect display even while the main reels MR1, MR2, MR3 are rotating. For example, when the symbol “peach” is displayed on the main reel MR1 and the small role <2> is won, the sub control board 300 displays the symbol “peach” on the sub reel SR1, as shown in FIG. 14B. Let Then, a character decorated with “Go” composed of a transmission image by the liquid crystal display panel LCD is displayed on the display surfaces of the remaining rotating sub reels SR2 and SR3. In this way, it is possible to perform an effect display that prompts an operation to stop the remaining main reels MR2 and MR3 and raises a sense of expectation for winning.

  According to the slot machine 10 having such a configuration, the main reel device 100 that presents the result of the game is miniaturized and provided on the upper panel portion 13, whereby the middle panel portion 14 is used as an area for producing the game. And since the effect display device composed of the sub-reel device 200 and the liquid crystal display panel LCD is installed in the area related to the effect expanded in the middle panel portion 14, it is possible to effectively display the effect of the game. Can do.

  Further, various display forms can be produced by rotating the sub reels SR1, SR2, SR3 and changing their rotation speed, direction, and the like. Furthermore, by overlapping the transmitted image by the liquid crystal display panel LCD with the symbols of the sub reels SR1, SR2, SR3, it is possible to produce an effect that appeals to the player's vision, and such a visual effect display is provided. However, various information regarding the game can be surely notified to the player. Thereby, it is possible to provide a highly entertaining game that prioritizes visual effects.

  As shown in FIG. 15, the slot machine 10 of the present invention may have a structure in which the main reel device 100 is disposed below the effect display device including the liquid crystal display panel LCD and the sub reel device 200. FIG. 15 is a front view illustrating the external structure of the slot machine 10 in which such a front panel portion is arranged and configured.

  According to the slot machine 10 in which the front panel portion is arranged and configured as described above, the positions of the main reels MR1, MR2, and MR3 that present the game result are close to each other above the operation unit 16 that instructs to start and end the game. Therefore, in addition to the advantageous effects of the slot machine 10 in the above-described embodiment, the operability in the game can be improved.

  Further, as shown in FIG. 16, the slot machine 10 of the present invention is provided with a large liquid crystal display panel LCD in almost the entire area of the front panel portion, and through transparent areas WD3 and WD4 formed in the liquid crystal display panel LCD.
