A support plate MS2 to which MM2 is assembled, a main reel MR3 and a support plate MS3 to which a stepping motor MM3 is assembled are respectively mounted, and one end of each of the support plates MS1, MS2, and MS3 is one end of the reel case cover 102. It is fixed with screws.

  Further, these first to third main reel units have basically the same size and structure, and are representative of the first main reel unit having the main reel MR1, the stepping motor MM1, and the support plate MS1. If it explains, it will be comprised as follows.

  First, as shown in FIGS. 6A and 7, the stepping motor MM1 is fixed to the plate surface of the support plate MS1 formed of metal or hard plastic by screwing or the like. A cylindrical relay shaft 105 formed of hard plastic and having a flange portion 105a is fitted on the rotation shaft 104 of the stepping motor MM1 orthogonal to the support plate MS1, and a relay member formed of hard plastic and having a projection 106a. 106 is fitted in the relay shaft 105. Furthermore, the tip of the relay shaft 105 penetrates the relay member 106 and protrudes toward the main reel MR1.

  On the other hand, the main reel MR1 is formed entirely of hard plastic and extends radially from the base 107 as shown in FIG. 6 (b) and a cup-shaped base 107 assembled to the tip of the relay shaft 105. A plurality of existing 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.

The relay shaft 105, the relay member 106, and the base 107 are fixed, and the main reel MR1 rotates 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.

  Note that the second main reel unit having the main reel MR2 and the stepping motor MM2 assembled to the support plate MS2 shown in FIG. 4, and the third main reel unit having the main reel MR3 and the stepping motor MM3 assembled to the support plate MS3. 8 has the same basic structure as the first main reel unit described above, 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.

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 concentrated 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. 15 (a) associates 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. 15B is a schematic diagram showing the principle of the role lottery. In FIG. 15A, 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 stopped on the effective line L1 (see FIG. 1) of the first transparent window WD1 in a combination of “watermelon”-“peach”-“peach”, This is a function of paying out 13 game medals to a player (that is, 13 times the number of bets) and providing a privilege that allows the player to advance the game in an advantageous manner.

  In the replay, 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 peripheries of the main reels MR1, MR2, and MR3 shown in FIG. When the symbols drawn on the surface are all aligned on the effective line L1 of the first transparent window WD1 with the combination of "grape"-"grape"-"peach", the game medals are not paid, but the game It is a role that gives the player 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 aligned on the effective line L1 of the first transparent window WD1 with the combination of “watermelon”-“grape”-“lemon” and stopped, 13 (that is, bet It is a role of paying game medals of 13 times the number.

  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 are aligned and stopped on the active line L1 of the first 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 first transparent window WD1, regardless of the symbols of the remaining main reels MR2 and MR3. This is the role of paying three game medals (three 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. 15B, 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. 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, as shown in FIG. 14, performs a lottery drawing, 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 sub-control board. 300, the sub reel device 250 is driven, and the first effect display device 200 and the second effect display device 220 display effects on the respective display surfaces 1a, and the effect lamps 13a to 13e, 14b, 14c, By driving 15b and 15c and the speakers Q1 to Q4, an effect that appeals 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 this order, the sub-control board 300 is instructed to drive the sub-reel device 250 to cause the first effect display device 200 and the second effect display device 220 to display effects on the display surface 1a. The lighting and blinking operations of 13a to 13e, 14b, 14c, 15b, and 15c and the sound effects of the speakers Q1 to Q4 are also changed to produce an effect appealing to the visual and auditory sense corresponding to the player's stop operation.

  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 brake controlled in the order in which they were stopped in order to align the symbols on the effective line L1 of the display surface with a combination of "watermelon"-"peach"-"peach" and stop each of them. Stop within 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 the symbol t1) drawn at the bottom of the reel tape MTP1 shown in FIG. 8 is the first transparent window WD1. If the player stops the stop button BP1 when positioned on the effective line L1, the spinning device substrate 900 has the control frame number Nz set to 3 (Nz ≦ 3). The 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 symbol “watermelon” indicated by the symbol t2 in FIG. 8 is positioned on the effective line L1 of the first transparent window WD1, the player presses the stop button BP1. If the stop operation is performed, the spinning device substrate 900 stops the main reel MR1 at the time t2 when the stop operation is performed. In addition, when the symbol “watermelon” indicated by the symbol t2 is almost separated from the effective line L1 of the first transparent window WD1, the number of control frames Nz is set to 3 (Nz ≦ 3). Therefore, the main reel MR1 is rotated by a maximum of three frames, and the stepping motor MM1 and the main reel MR1 are stopped when the “watermelon” symbol indicated by the symbol t3 is positioned on the effective line L1. Then, the symbol of “watermelon” corresponding to the winning combination 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 confirms winning when the three symbols of the main reels MR1, MR2, MR3 are aligned on the effective line L1 in a combination corresponding to the lottery role shown in FIG. 15A. If it is determined, the power supply device board 500 is instructed to pay out a predetermined number of game medals.

  Further, the main control board 700 instructs the sub control board 300 to perform an effect for notifying the winning decision, and then completes the control for one game, and the player starts the next game. Wait until When the start lever BL or the like is turned on, the progress of the next game is controlled.

  As described above, according to the slot machine 10 of the present embodiment, the central portions 3b and 4b of the display units 3 and 4 on the front side of the main reel device 100 are controlled so that the liquid crystal 6 becomes transparent, and the front side of the sub reel device 250 Since the holes 3a and 4a are formed in the display portions 3 and 4, the player can visually recognize the main reel device 100 and the sub reel device 250 through the central portions 3b and 4b and the holes 3a and 4a. In addition, the first effect display device 200 and the second effect display device 220 arranged around these devices can be visually recognized.
