  The drive pattern data of the electric motor 34 stored in the storage device ROM of the main control board 60 described above is stored as a plurality of types of pulse pattern data having different numbers of pulses transmitted within a predetermined time. When any selected pulse pattern is transmitted to the electric motor 34 formed of a stepping motor, the electric motor 34 is rotationally driven based on the received pulse pattern. The endless belt 33 is rotated in a predetermined rotation mode by the rotational drive of the pulley 30a by the electric motor 34. Here, examples of the rotation mode of the endless belt 33 include constant speed continuous rotation, intermittent rotation, reciprocal rotation, rotation at different speeds, and various rotation modes appropriately combining these. The rotation timing, rotation amount, rotation direction, and rotation speed are controlled by the main control board 60.

Next, rotation control of the endless belt 33 by the main control board 60 will be described according to the operation of the pachinko gaming machine.
When a game ball is launched from a launching device (not shown) to the game area 4 of the game board 1, the game ball passes through the normal symbol start gate 12, and the normal symbol start switch S2 is turned on to send a ball detection signal. The main control board 60 recognizes the signal. In response to this signal, the central control unit CPU for main control of the main control board 60 starts the symbol variation of the ordinary symbol display device 9, and the lottery from the required random number tables u and v stored in the storage device ROM. The winning random number value U, the normal winning symbol random number value V, and the like are selected, and each random number value is temporarily stored in the storage device RAM. Then, after the start of symbol variation in the normal symbol display device 9, the main control central control unit CPU determines the normal random number value U stored in the storage device RAM, and the normal random number value U is a predetermined random number value. In the case of, fluctuation of the normal symbol is stopped in a hit symbol mode based on the normal symbol random value V. When the normal hit random number value U is not a predetermined hit random number value, the fluctuation of the normal symbol is stopped in a lost symbol form.

  On the other hand, the endless belt 33 of the start winning device 28 rotates in a normal operation mode in which the endless belt 33 is always transferred at a constant speed in a normal state. As a result, as shown in FIG. 5 (a), the non-opening portion 32 is positioned above the start winning opening 29 and shields the starting winning opening 29 as shown in FIG. As shown in (c), a game in which the opening 31 is located above the start winning opening 29 and the non-opening 32 is located below the starting winning opening 29 and passes through the opening 31 located above the opening winning opening 29. A guide state in which the ball w is received by the non-opening portion 32 positioned below and the flow into the start winning opening 29 is facilitated alternately occurs. Here, in the first embodiment, since the opening 31 and the non-opening 32 are provided with substantially the same length in the circumferential direction, the upper half of the endless belt 33 is formed by the non-opening 32 in the shielding state. All the parts are covered, and the inflow of the game ball w to the start winning opening 29 becomes impossible. On the other hand, in the guide state, all of the upper half of the endless belt 33 is opened by the opening 31, and the game ball w flows into the start winning opening 29 from all open areas corresponding to the lateral width of the endless belt 33. Is possible. As described above, the state in which the game ball w can flow into the start winning opening 29 and the state incapable of flowing in are obtained by the displacement of the opening 31 and the non-opening 32 due to the rotation of the endless belt 33. The operation mode becomes novel, and it is possible to improve visual interest and playability.

  In addition, on the inner peripheral surface of the non-opening portion 32 of the endless belt 33, the guide inclined portion 44 that rolls the game ball w toward the start winning port 29 in a state where the non-opening portion 32 is positioned below the start winning port 29. Thus, in the guidance state, the game ball received by the non-opening portion 32 is rolled to the start winning opening 29 side by the guide inclined portion 44, so that the start winning is achieved more quickly and reliably. The mouth 29 can be awarded.

  Further, when one of the shielding state (see FIG. 5 (a)) and the guiding state (see FIG. 5 (c)) shifts to the other state, it is shown in FIG. 5 (b). As described above, the game ball shielding area 49 generated by the non-opening portion 32 above the start winning opening 29 and the game ball guide area 50 generated by the non-opening section 32 below the starting winning opening 29 rotate the endless belt 33. Increases or decreases relatively. As a result, when the game ball w that has tumbled down the game area 4 (see FIG. 1) and reached the upper end of the endless belt 33 falls on the game ball shielding area 49, it flows into the start winning opening 29. On the other hand, when the game ball w falls to the opening 31 located above the start winning opening 29, the game ball w passes through the opening 31 and is received by the game ball guide area 50. , It becomes possible to flow into the start winning opening 29. As described above, the game ball shielding area 49 and the game ball guide area 50 are gradually displaced while relatively increasing and decreasing with the rotation of the endless belt 33, so that the winning rate of the game balls w flowing into the start winning opening 29 is increased. Can be changed.

  When the endless belt 33 is rotated in the normal operation mode, when the normal symbol of the normal symbol display device 9 stops in the target symbol mode, the endless belt 33 is controlled by the main control. The substrate 60 is rotationally controlled in a special operation mode. In this special operation mode, the non-opening portion 32 is instantaneously rotated below the start winning opening 29, and the game ball w received by the non-opening portion 32 is guided in a guide state that facilitates inflow into the starting winning opening 29. Control is performed to temporarily stop for a time (for example, 3 seconds). Here, in the normal operation mode, the shield state and the guide state are alternately generated along with the constant transfer of the endless belt 33 at a constant speed, and the game ball w can flow into the start winning opening 29 only in the guide state. Therefore, compared to the low winning rate, in the special operation mode, the non-opening portion 32 instantly rotates below the starting winning port 29 and stops temporarily in its guiding state, so the winning rate is high. Become. Thereby, the winning rate to the start winning opening 29 can be made different between the normal operation mode and the special operation mode.

  Further, in this first embodiment, the endless belt 33 is replaced with the rotation control in the normal operation mode and the special operation mode as described above, and the normal state in which the endless belt 33 is stopped in the shielded state. Thus, when the normal symbol of the normal symbol display device 9 is stopped in a winning symbol pattern, the non-opening portion 32 is instantaneously rotated below the start winning opening 29 and received by the non-opening portion 32. The game ball may be controlled to turn to a guidance state that facilitates the flow of the game ball into the start winning opening 29. In this case, the return control from the guidance state to the normal state is performed after a lapse of a predetermined time (for example, 3 seconds) from the time when the guidance state is reached, or by a special symbol start switch by the inflow of game balls to the start winning opening 29 When S1 is turned ON, a game ball detection signal can be sent out from the special symbol start switch S1. In such a configuration, in the normal state, the endless belt 33 is stopped in the shielded state, so that the inflow of the game ball to the start winning opening 29 can be disabled and the predetermined operating condition is satisfied. As a trigger, that is, when a normal symbol hits and stops in a symbol form, the game ball winning control is performed by switching from the normal state to a guiding state in which the game ball can flow into the start winning opening 29. be able to.

  FIG. 7 shows a modified embodiment of the first embodiment. In this modified embodiment, the circumferential lengths of the opening 31 and the non-opening 32 formed in the endless belt 33 are different from each other. Yes, the opening 31 is generally sized to allow one game ball to pass. Other configurations are the same as those of the first embodiment, and the same parts are denoted by the same reference numerals and redundant description is omitted.

  In such a configuration, when the endless belt 33 is rotated in the above-described normal operation mode in which the endless belt 33 is always transported at a constant speed, the endless belt 33 is rotated as shown in FIGS. In addition, when the opening 31 is located at any position on the upper half side of the endless belt 33, the game ball w that has passed through the opening 31 is received by the non-opening 32 positioned below, and the starting prize opening 29. As a result, the inflow route of the game balls w can be changed, and the winning rate of the game balls w flowing into the start winning opening 29 can be reduced as compared with the first embodiment.

  8 and 9 show still another modified embodiment of the first embodiment. In this modified embodiment, the circumferential lengths of the opening 31 and the non-opening 32 formed in the endless belt 33 are mutually different. The non-opening portion 32 is generally sized so as not to pass one game ball. Other configurations are the same as those of the first embodiment, and the same parts are denoted by the same reference numerals and redundant description is omitted.

  In such a configuration, when the endless belt 33 is rotated in the normal operation mode as described above, which is always transferred at a constant speed, the endless belt 33 is rotated, as shown in FIG. The non-opening part 32 shields the start winning opening 29 at a position above 29, and the opening 31 is located above and below the starting winning opening 29 as shown in FIG. The state where w can pass in the vertical direction and the non-opening portion 32 receives the game ball w at a position below the start winning opening 29 and easily flows into the starting winning opening 29 as shown in FIG. Each of the guidance states can be generated. Thereby, the subsequent movement of the game ball w that has reached the upper end of the endless belt 33 is rich in change.

  10 and 11 show a second embodiment. In the second embodiment, the endless belt 33 is provided with a narrow opening 31a and a wide opening 31b having different circumferential lengths. Yes. Here, the narrow opening 31a is formed to have a length that allows one game ball w to pass therethrough, and the wide opening 31b is formed to be longer than the narrow opening 31a. . The narrow opening 31a and the wide opening 31b are adjacent to each other via a non-opening 32 'having a length that prevents passage of at least one game ball w. Further, as shown in FIGS. 10A and 10B, the narrow opening 31a and the wide opening 31b are positioned above the start winning opening 29, respectively, and the non-opening 32 is in the starting winning opening 29. The game ball w received by the non-opening portion 32 is provided so as to generate a guiding state that facilitates the inflow into the start winning opening 29.

  Further, as shown in FIG. 10 (a), the endless belt 33 normally has a narrow opening 31a positioned above the start winning opening 29, and the normal symbol of the above-described normal symbol display device 9 is hit. When stopped in the design mode, this is used as an opportunity to rotate the wide opening 31b so as to be positioned above the start winning opening 29 as shown in FIG. In this case, the return control from the state in which the wide opening 31b is located above the start winning opening 29 to the state in which the narrow opening 31a is located above the starting winning opening 29 is performed by the wide opening 31b being the start winning opening. The special symbol start switch S1 is turned ON when a predetermined time (for example, 3 seconds) elapses from the time when the state is located above 29, or when the game ball flows into the start winning opening 29, and the special symbol start switch S1 is turned ON. It can be triggered by a game ball detection signal being sent from the start switch S1.

  In this configuration, the winning rate in the state where the wide opening 31b is located above the start winning opening 29 is higher than the winning rate in the state where the narrow opening 31a is located above the starting winning opening 29. From the state where the narrow opening 31a having a low winning rate is positioned above the start winning opening 29, when a predetermined operating condition is satisfied, that is, when a normal symbol stops in a winning symbol mode, Since the rate wide opening 31b is converted to a state positioned above the start winning opening 29, the winning rate can be changed in the same manner as in the conventional tulip type start winning device. Further, since the narrow opening 31a and the wide opening 31b are provided adjacent to each other via a non-opening 32 'having a length that prevents passage of at least one game ball w, the low winning rate is narrow. When the width opening 31a and the wide opening 31b having a high winning rate are switched by the rotation of the endless belt 33, the non-opening 32 '(or the non-opening 32) between the both openings 31a and 31b is the start prize. A shielding state that shields the start winning opening 29 at a position above the opening 29 temporarily occurs, and in this shielding state, the winning rate is zero, so that the winning rate is changed in a different manner from the conventional tulip type starting winning device. Can be changed.

  FIGS. 12 and 13 show a third embodiment. In this third embodiment, the endless belt 33 includes one narrow opening 31a and two wide openings 31b having different circumferential lengths. 31b. Here, the narrow opening 31a is formed to have a length that allows one game ball w to pass therethrough, and the wide openings 31b and 31b are formed to be longer than the narrow opening 31a. ing. The narrow opening 31a and the wide openings 31b and 31b are adjacent to each other via non-openings 32 'and 32' having a length that prevents passage of at least one game ball w. Further, as shown in FIG. 12A, the narrow opening 31a is opposed to the non-opening 32 above the start winning opening 29 in a state where the non-opening 32 is positioned below the start winning opening 29. On the other hand, the two wide openings 31b, 31b are provided in the position where the other wide opening 31b is located in the state where the one wide opening 31b is positioned below the start winning opening 29 as shown in FIG. A portion 31b is provided above the start winning opening 29 at a position facing the one wide opening 31b.

  Further, as shown in FIG. 12 (a), the endless belt 33 allows the game ball that has passed through the narrow opening 31 a to pass through the non-opening portion 32 in a state where the non-opening portion 32 is positioned below the start winning opening 29. And the first widened state that makes it easy to flow into the start winning opening 29 and two wide openings 31b and 31b above and below the starting winning opening 29 as shown in FIG. The rotation is controlled so that a second rotation state in which the respective game balls are positioned and allow the game balls to pass in the vertical direction is generated.

  In such a configuration, when the endless belt 33 is controlled to rotate in a normal operation mode in which the endless belt 33 is always transferred at a constant speed in a normal state in the same manner as in the first embodiment, along with the rotation, FIG. As shown in (a), in a state where the non-opening portion 32 is positioned below the start winning opening 29, the game ball that has passed through the narrow opening 31a is received by the non-opening portion 32 and flows into the starting winning opening 29. As shown in FIG. 12 (b), the two wide openings 31b and 31b are positioned above and below the start winning opening 29, respectively, so that the game ball can be moved vertically. As shown in FIG. 12C, a second rotating state to be passed and a shielding state in which the non-opening portion 32 is positioned above the start winning opening 29 and shields the starting winning opening 29 are sequentially generated. It becomes. In the first turning state, the game ball that has passed through the narrow opening 31 a positioned above the start winning opening 29 is received by the non-opening 32 positioned below to flow into the starting winning opening 29. While an easy guiding state can be generated, in the second rotation state, the game ball that has reached the upper side of the endless belt 33 can be passed through as it is. As a result, it is possible to selectively cause a guided state and a non-guided state (passable state). In particular, in the second rotation state, the game ball moves through the endless belt.

  Further, when the normal symbol of the normal symbol display device 9 stops in the symbol pattern when the endless belt 33 is rotated in the normal operation mode as described above, the endless belt 33 is The control board 60 controls the rotation in a special operation mode. In this special operation mode, as shown in FIG. 12 (a), the non-opening portion 32 is instantaneously rotated below the start winning opening 29, and to the start winning opening 29 of the game ball w received by the non-opening portion 32. Control is performed to temporarily stop for a predetermined time (for example, 3 seconds) in a guidance state that facilitates the inflow of water. Here, in the normal operation mode, the guidance state, the passing state, and the shielding state are sequentially generated along with the constant transfer of the endless belt 33 at a constant speed, and the inflow of the game ball w to the start winning opening 29 only in the guidance state. Therefore, in the special operation mode, the non-opening portion 32 instantaneously rotates below the start winning opening 29 and temporarily stops in the guidance state. Becomes higher. Thereby, the winning rate to the start winning opening 29 can be made different between the normal operation mode and the special operation mode.

  Further, as described above, when the special symbols A, B, and C that are variably displayed on the display screen 7 of the symbol display device 6 (see FIG. 1) are fixedly displayed in a predetermined symbol pattern combination, a variable prize is awarded. A special game operation is performed as a big hit to open the big prize opening 22 of the device 20 (see FIG. 1) in a predetermined opening manner. When the big prize opening 22 of the variable prize winning device 20 is opened, the second rotation is performed. By turning the endless belt 33 so as to cause a state, the game ball passing through the two wide openings 31b, 31b of the endless belt 33 from the top to the bottom is opened. 22 will flow into. As a result, during the execution of the special game operation so far, the game ball that has flowed into the conventional tulip-type start winning device at the upper position can be made to flow into the variable winning device 20, so that the variable winning device 20 As a result, the special game operation can be advanced promptly.

  14 and 15 show a fourth embodiment. In the fourth embodiment, the endless belt 33 includes one wide opening 31b and two narrow openings 31a, each having a circumferential length different from each other. 31c. Here, the narrow opening portions 31a and 31c are formed to have a length that allows one game ball w to pass therethrough, and the wide opening portion 31b is longer than the narrow opening portions 31a and 31c. Is formed. The narrow opening 31a and the wide opening 31b are adjacent to each other via a non-opening 32a having a length that prevents passage of at least one game ball w, and the narrow opening 31a and the other As shown in FIG. 15B, the narrow-width opening 31c is adjacent via a non-opening 32b having a length that can shield the start winning opening 29. In addition, as shown in FIG. 15A, the one narrow opening 31 a has the non-opening 32 above the start winning opening 29 in a state where the non-opening 32 is positioned below the start winning opening 29. As shown in FIG. 15C, the other narrow opening 31c is provided at a position opposite to the start winning opening 29 with the wide opening 31b positioned below the starting winning opening 29. Above the wide opening 31b.

  Further, as shown in FIG. 15 (a), the endless belt 33 allows the game ball that has passed through the narrow opening 31a to pass through the non-opening 32 in a state where the non-opening 32 is positioned below the start winning opening 29. And a guide state that facilitates the inflow into the start winning opening 29, and the non-opening portion 32b is positioned above the start winning opening 29 to shield the starting winning opening 29 as shown in FIG. As shown in FIG. 15C, the narrow opening 31c is positioned above the start winning opening 29, and the wide opening 31b is positioned below the starting winning opening 29. Are pivoted so as to sequentially generate a passable state in which they pass through in the vertical direction.

  Further, a special symbol start switch S1 is disposed in the gap surrounded by the endless belt 33 so as to be positioned above the start winning opening 29. As shown in FIG. 14, the special symbol start switch S1 is projected horizontally in a state of being fixed to the front plate 36 of the support case 35, and has a ball detection hole 52 at the front thereof. The narrow openings 31a and 31c are opened at positions where they can communicate with each other. When the game ball passes through the ball detection hole 52, the special symbol start switch S1 is turned ON, and the special symbol is displayed on the display screen 7 of the symbol display device 6 (see FIG. 1) based on the game ball detection signal. A symbol generation process for variably displaying A, B, and C is executed. In addition, a winning detection switch S6 (see FIG. 6) for detecting a game ball flowing in from the start winning opening 29 is disposed inside the support case 35, and based on a gaming ball detection signal from the winning detection switch S6. Thus, a predetermined number (for example, five) of prize balls are paid out.

  The endless belt 33 of the start winning device 28 in this fourth embodiment is controlled to rotate based on the special symbol start memory number stored in a partial area of the storage device RAM of the main control board 60 (see FIG. 6). . That is, the guidance state shown in FIG. 15 (a) is always maintained until the number of special symbol starting memories is two, and when the number of special symbol starting memories becomes three, the rotation is started and a predetermined time (for example, 3 seconds) is reached. This is the passable state shown in FIG. After this passable state is maintained for a predetermined time (for example, 3 seconds), the predetermined time (for example, 3 seconds) is applied again to return to the guide state shown in FIG. Then, when a predetermined time (for example, 3 seconds) elapses after returning to the guidance state, the guidance state is maintained if the number of special symbol starting memories is two or less, and if it is three or more, the guidance state is again passed. Such rotation is started. As a result, when the number of special symbol starting memories becomes three or more, the shielding state shown in FIG. 15 (b) and the passable state shown in FIG. 15 (c) are caused in order. The game ball detection by the symbol start switch S1 and the winning detection switch S6 is disabled to suppress the generation of a new special symbol start memory and the payout of the prize ball, while in the passable state, the game ball by the special symbol start switch S1. Only detection is allowed, and only the generation of a new special symbol start memory is allowed, and the payout of prize balls is suppressed. Further, if the variation time of the special symbols A, B, and C displayed on the display screen 7 of the symbol display device 6 (see FIG. 1) is too long, the number of special symbol starting memories is likely to increase. Control is performed so that the normal losing symbol variation time, excluding long special fluctuations, is about 10 seconds, and the losing symbol variation time is about 5 seconds when the number of special symbol starting memories is four.

  Here, since the special symbols A, B, and C displayed on the display screen 7 of the symbol display device 6 do not fluctuate frequently, it is desirable to increase the number of triggers for the special symbol as much as possible. As in the first to third embodiments described above, the game ball that has flowed into the start winning opening 29 is detected by the special symbol start switch S1, and the game ball detection signal is used as a trigger for starting the special symbol. In this case, if the number of inflows of game balls to the start winning opening 29 is increased, the number of prize balls to be paid out is increased accordingly, and the profit rate of the game store is lowered. Further, if the special symbol start switch S1 is simply disposed on the pass-through gate so that the prize ball is not paid out, the player's game ball will not be fast. Therefore, in the above configuration, by controlling the rotation of the endless belt 33 based on the special symbol start memory number as described above, the number of game ball detection signals that trigger the start of the special symbol, A reasonable balance can be achieved with the number of payouts.

  Note that the rotation control of the endless belt 33 may be based on a predetermined operation time, in addition to being performed based on the special symbol start memory number as described above. That is, for example, after the guiding state shown in FIG. 15 (a) is maintained for a predetermined time (for example, 3 seconds), the endless belt 33 is rotated for a predetermined time (for example, 3 seconds), and FIG. A rotation mode is shown in which the passable state shown in FIG. 15 is maintained, and after this passable state is maintained for a predetermined time (for example, 3 seconds), the predetermined time (for example, 3 seconds) is applied again to return to the guide state shown in FIG. It can be repeated.
