A configuration according to claim 3 is proposed. In this case, it is preferable that the opening and the non-opening formed in the endless belt have substantially the same length in the circumferential direction.

  The circumferential length of the opening and the non-opening formed in the endless belt is such that the winning opening is shielded by the non-opening at the position above the winning opening, and the opening is not opened at the position below the winning opening. The endless belt has a guide state in which the game ball is received by the portion and easy to flow into the winning port, and a state in which the opening is positioned above and below the winning port and the game ball can pass vertically. The structure (claim 4) set so that it may each arise with rotation is proposed. In this case, it is preferable that the opening and the non-opening formed in the endless belt have different lengths in the circumferential direction, and the length of the non-opening in the circumferential direction is such that at least one game ball cannot pass through. That which is small is suitable.

  Furthermore, as the opening of the endless belt, a narrow opening and a wide opening having different circumferential lengths are provided, and the narrow opening and the wide opening are located above the winning opening, respectively. Thus, the non-opening portion is located below the winning opening so that a guiding state for facilitating the flow of the gaming ball received by the non-opening portion into the winning opening is generated, and the gaming ball received by the non-opening portion is A configuration has been proposed in which the endless belt is controlled to rotate so that the narrow opening and the wide opening are alternately positioned above the winning opening each time it flows into the winning opening. The In this case, the narrow opening and the wide opening are preferably provided adjacent to each other via a non-opening having a length that prevents passage of at least one game ball.

  Further, the present invention provides a pachinko gaming machine in which a game area in which a game ball rolls and flows is defined on a game board surface, and the variable prize apparatus is arranged in the game area, the variable prize device is arranged on the game board surface side. A winning opening opened forward; a plurality of pulleys disposed on the left and right sides of the winning opening; an opening through which a game ball can pass and a non-opening through which the game ball cannot pass; An endless belt that is transported around the winning opening at the front position of the winning opening, a guide inclined member that is arranged immediately below the winning opening and rolls the game ball toward the winning opening, Drive means for rotating at least one of the pulleys to rotate the endless belt, and the endless belt has at least a non-opening portion located above the winning opening, and the non-opening portion. The shielding state that shields the top of the winning opening, and the opening is A pachinko game machine, characterized in that the passage of the game ball located above the prize port is provided so as to produce a non-blocking state capable (claim 6).

  The opening of the endless belt includes a narrow opening and a wide opening having different circumferential lengths, and each time the game ball flows into the winning opening, the narrow opening and the wide opening A configuration (Claim 7) is proposed in which the endless belt is rotationally controlled so as to be alternately positioned above the winning opening.

In such a configuration, when the opening 31 is located at any position on the upper half side of the endless belt 33 as shown in FIGS. The game ball w that has passed through the opening 31 is received by the non-opening 32 positioned below and flows into the winning opening 29. Thereby, the inflow route of the game ball w can be changed, and the winning rate of the game ball w flowing into the winning port 29 can be reduced as compared with that of the first embodiment.

  FIGS. 8 and 9 show a second embodiment, in which 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 non-opening 32 is of a size that generally prevents one game ball from passing therethrough. 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, as shown in FIG. 8 (a), the endless belt 33 is rotated, so that the non-opening portion 32 shields the winning opening 29 above the winning opening 29, as shown in FIG. As shown in (b), the opening 31 is located above and below the winning opening 29 so that the game ball w can pass in the vertical direction, and as shown in FIG. A guide state in which the non-opening portion 32 receives the game ball w at the lower position and facilitates inflow into the winning opening 29 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 third embodiment. In the third 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. .

It has come to be.

  In such a configuration, the winning rate in the state where the wide opening 31b is positioned above the winning port 29 is higher than the winning rate in the state where the narrow opening 31a is positioned above the winning port 29, Each time the game ball w flows into the winning opening 29, the narrow opening 31a having a low winning percentage and the wide opening 31b having a high winning percentage are alternately converted into a state of being positioned above the winning opening 29. Therefore, the winning rate can be changed in the same manner as the conventional tulip-shaped variable 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 wide opening 31a and the wide opening 31b having a high winning rate are alternately switched by the rotation of the endless belt 33, the non-opening 32 ′ (or the non-opening 32) between the openings 31a and 31b is formed. A shielding state that shields the winning opening 29 temporarily occurs at a position above the winning opening 29, and in this shielding state, the winning rate is zero, so that the winning rate is different from the conventional tulip type variable winning device. Can be changed.

  FIGS. 12 to 14 show a fourth embodiment.

The game ball w that has passed through the opening 31 is received by the guide inclined member 51 so that the game ball w can flow into the winning port 29, while the non-opening 31 is positioned above the winning port 29, In the shielding state where the non-opening portion 31 shields the top of the winning opening 29, the inflow of the game ball w to the winning opening 29 becomes impossible. In this way, the non-opening 31 is located above the winning opening 29 and the non-opening 31 shields the winning opening 29, and the opening 31 is located above the winning opening 29. The non-shielding state that allows the passing of the game ball w is obtained by the displacement of the opening 31 and the non-opening 31 due to the rotation of the endless belt 33, so that the operation mode becomes novel and the appearance is interesting. And playability can be improved. In addition, the endless belt 33 can be continuously rotated to sequentially generate a shielded state and a non-shielded state, or can be instantaneously switched between a shielded state and a non-shielded state at regular intervals. The operation mode is also novel.

  FIGS. 15 and 16 show a modified embodiment of the fourth embodiment. In this modified embodiment, the endless belt 33 has a narrow opening 31a and a wide opening 31b having different circumferential lengths. Is provided. 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. .

Further, the non-opening portion 32 ′ is a portion other than the non-opening portion 32 ′ and the narrow opening 31 a and the wide opening 31 b adjacent to each other through the non-opening 32 ′.

  Further, as shown in FIGS. 15A and 15B, the endless belt 33 has either the narrow opening 31a or the wide opening 31b always above the winning opening 29, and the narrow opening Each time the game ball w that has passed through the portion 31a or the wide opening 31b is received by the guide inclined member 51 and flows into the winning opening 29, the narrow opening 31a and the wide opening 31b alternately above the winning opening 29. The rotation is controlled so as to be located at Here, the above-described winning detection switch S5 is disposed in the winning opening 29, and the endless belt 33 is controlled to rotate based on the detection signal of the game ball w sent from the winning detection switch S5. It is like that.

  In this configuration, as in the third embodiment, the wide opening 31b is positioned above the winning opening 29 as compared to the winning rate in the state where the narrow opening 31a is positioned above the winning opening 29. Each time the game ball w flows into the winning opening 29, the narrow opening 31a having a low winning ratio and the wide opening 31b having a high winning ratio alternately alternate above the winning opening 29. Therefore, the winning rate can be changed in the same manner as the conventional tulip-shaped variable 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 wide opening 31a and the wide opening 31b having a high winning rate are alternately switched by the rotation of the endless belt 33, the non-opening 32 ′ (or the non-opening 32) between the openings 31a and 31b is formed. A shielding state that shields the winning opening 29 temporarily occurs at a position above the winning opening 29, and in this shielding state, the winning rate is zero, so that the winning rate is different from the conventional tulip type variable winning device. Can be changed.
