For example, the side plate 81 is rotatably supported by the rotation shaft 74 outside the side wall 68 of the guide rod 63.

  The side plate 81 is provided with a bearing hole 83 into which the rotation shaft 74 on the guide rod 63 side is fitted, and a guide hole 84 into which the rotation restriction pin 75 is fitted. The guide hole 84 has a substantially horizontal position (indicated by a two-dot chain line in FIG. 5; hereinafter referred to as an attaching / detaching position) and a downwardly substantially vertical position (indicated by a solid line in FIG. 5; hereinafter referred to as a guide position). Is formed in a 1/4 arc-shaped elongated hole corresponding to the locus of the rotation restricting pin 75 when being rotated between. Thereby, the rotation range of the guide passage 64 is restricted within a range of about 90 degrees between the attachment / detachment position and the guide position.

  Further, in the guide hole 84, in the vicinity of both end portions thereof, protrusions 85a (attachment / detachment position holding means) and 85b (guide position holding means) so that the hole width is slightly narrower than the diameter of the rotation restricting pin 75. Is provided. At the time of rotation of the guide passage 64, the rotation restricting pin 75 reaches both ends of the guide hole 84 while spreading the protrusions 85a and 85b outward, and positions of both ends of the guide hole 84 by the protrusions 85a and 85b. Retained. That is, the protrusions 85a and 85b hold the guide passage 64 at the attachment / detachment position and the guide position by holding the rotation restricting pins 75 at both ends of the guide hole 84, respectively.

  The guide passage 64 is substantially perpendicular to the guide rod 63 at the guide position, and its front side (front edge 81a of the side plate 81) is substantially in contact with the back side of the game board 13, and is substantially parallel to the guide rod 63 at the attachment / detachment position. Thus, the lower side (the front edge portion 81a of the side plate 81) is substantially coincident with the lower surface side of the bottom wall 71 of the guide rod 63 or is positioned slightly above.

  The back plate 82 is integrally provided, for example, so as to connect the rear edge 81b of the side plate 81 to the left and right, and covers the rear side of the guide passage 64 at the guide position. The back plate 82 is provided in a range of a predetermined width from the downstream end side to the upstream side of the guide passage 64 so as not to interfere with the rear end side of the guide rod 63 when the guide passage 64 is in the attachment / detachment position. .

  The guide passage 64 needs to be formed in such a length that a gap of at least one game ball is provided between the downstream end side of the back plate 82 and the guide rod 57 of the big winning means 25 at the attaching / detaching position.

Since the guide passage 64 is substantially straight in the front and rear direction with the guide rod 63 at the attachment / detachment position, the guide passage 64 can be easily inserted without interfering with the edge of the attachment hole 13a. Further, at this time, since the protrusion 85a in the guide hole 84 restricts the movement of the rotation restricting pin 75 and the guide passage 64 is held at the attachment / detachment position, the guide passage 64 does not wobble and the operation is performed more easily. be able to.

  When the solenoid 65, the guide rod 63, etc. are stored in the mounting hole 13a while the guide passage 64 is inserted into the mounting hole 13a, the back side of the main body 61 is brought into contact with the front surface of the game board 13 (FIG. 7B). Subsequently, the guide passage 64 is rotated approximately 90 degrees from the attachment / detachment position to the guide position (FIGS. 7C and 7D). As a result, the front edge 81a of the side plate 81 of the guide passage 64 comes into contact with the back side of the game board 13. Finally, the main body 61 may be fixed to the game board 13 using fixing means such as screws. The guide passage 64 is held at the guide position by the protrusion 85 b in the guide hole 84 restricting the movement of the rotation restricting pin 75.

  When the stop symbol after the fluctuation of the normal symbol display means 30 becomes a predetermined hitting state and the opening / closing claw 31 of the special symbol starting means 24 is opened, and the game ball wins in the winning hole 67, the game ball is detected. After being detected by the switch 69, it is guided to the back side of the game board 13 by the guide rod 63 through the opening 68. Then, it flows downward from the opening 73 on the rear end side of the guide rod 63 and is guided downward along the back side of the game board 13 by the guide passage 64. At this time, the guide passage 64 is held at the guide position by the protrusion 85b in the guide hole 84 restricting the movement of the rotation restricting pin 75. For example, it is assumed that the game ball collides with the back plate 82 or the like. Can reliably guide the game ball without swinging.

  The game ball guided downward along the back side of the game board 13 by the guide passage 64 falls onto the guide rod 57 of the big winning means 25 and is guided backward, and then from the rear side of the big winning means 25. It falls to the lower sphere collecting cover 35 side.

  As described above, in the present embodiment, the guide passage 64 is rotatably provided on the back side of the special symbol starting means 24, so that the special symbol starting means 24 is mounted on the game board 13 together with the guide passage 64 on the back side. On the other hand, it can be easily and reliably attached and detached.

  The special symbol starting means 24 is detachable from the front side with respect to the game board 13, and the guide passage 64 is rotatable between the guide position and the attachment / detachment position. The guide passage 64 can be rotated to the attachment / detachment position for easy attachment / detachment work. When the guide passage 64 is mounted on the game board 13, the guide passage 64 can be rotated to the guide position to ensure that the game ball is in a predetermined direction. (Downward) can be guided.

  A protrusion 85b is provided in the guide hole 84, and the movement of the rotation restricting pin 75 is restricted by the protrusion 85b so that the guide passage 64 is held at the guide position. Even if it collides, the game ball can be reliably guided without swinging.

  Since the protrusion 85a is provided in the guide hole 84 and the movement of the rotation restricting pin 75 is restricted by the protrusion 85a, the guide passage 64 is held at the attachment / detachment position. The guide passage 64 does not fluctuate when attaching to or detaching from the game board 13, and the work can be performed more easily.

  FIGS. 10 and 11 illustrate a second embodiment of the present invention. A guide lever 64 is attached to and removed from the first embodiment by a fixing lever 91 (attachment / detachment position holding means, guide position holding means). Further, an example is shown in which it can be reliably held.

  As shown in FIGS. 10 and 11, a fixing lever 91 is mounted on the back side of the rear wall 72 of the guide rod 63 so as to be rotatable about a front-rear rotation shaft 92 provided on the lower side of the rear wall 72. Has been. The fixed lever 91 is integrally provided with a support portion 93 that is rotatably supported by the rotation shaft 92 and a lever portion 94 that protrudes along the rear wall 72 from the support portion 93. When facing upward, the end surface 94a substantially abuts the front surface 82a of the back plate 82 of the guide passage 64 in the attaching / detaching position, and when facing down, the front surface 94b of the back plate 82 of the guide passage 64 having the guiding position is located. The length is formed so as to substantially contact the back surface 82b.

  Further, the fixed lever portion 91 has a thickness in the front-rear direction that does not interfere with the back plate 82 when the guide passage 64 is rotated between the guide position and the attachment / detachment position with the lever portion 94 substantially horizontal, for example. Is formed.

  With the configuration as described above, when the lever portion 94 of the fixed lever 91 is directed upward when the guide passage 64 is in the attachment / detachment position, the end surface 94a of the lever portion 94 faces the front surface 82a of the back plate 82 of the guide passage 64 downward. If the guide passage 64 is fixed at the attachment / detachment position and the lever portion 94 of the fixing lever 91 is turned downward when the guide passage 64 is at the guide position, the front surface 94b of the lever portion 94 becomes the back surface 82b of the back plate 82. Is supported from the rear side, and the guide passage 64 is fixed to the guide position. Further, when the guide passage 64 is rotated, the lever portion 94 of the fixed lever 91 may be substantially horizontal.

  Thus, in the present embodiment, the guide lever 64 can be reliably fixed to the attachment / detachment position and the guide position by the fixing lever 91. In addition, since the guide passage 64 can be fixed in a state where the back side of the game board 13 is pressed, for example, when the special symbol starting means 24 is fixed to the game board 13 by a press-fit pin or the like, the fixed state is further stabilized. Can do.

  FIG. 12 illustrates the third embodiment of the present invention, and without using a separate member such as the fixing lever 91, the rotation shaft 74, the rotation regulating pin 75, the bearing hole 83, shown in the first embodiment, An example in which the guide position holding means 95 is configured by slightly changing the arrangement and shape of the guide holes 84 and the guide passage 64 can be easily and reliably fixed at the guide position by the guide position holding means 95 is shown.

  As shown in FIG. 12, in this embodiment, the rotation restriction pin 75 and the rotation shaft 74 are arranged vertically on the side wall 70 of the guide rod 63. The bearing hole 83 provided in the side plate 81 of the guide passage 64 is formed in a long hole shape along the longitudinal direction of the guide passage 64. Similarly, the guide hole 84 provided in the side plate 81 restricts the rotation of the rotation shaft 74 when the guide passage 64 is rotated between the attachment / detachment position and the guide position at the downstream end 83a of the bearing hole 83. Relative movement of the rotation shaft 74 to the upstream end portion 83b of the bearing hole 83 in a state where the 1/4 arc-shaped elongated hole portions 84a-84b corresponding to the locus of the pin 75 and the guide passage 64 are rotated to the guide position. It is comprised by the longitudinal direction long hole part 84b-84c corresponding to the locus | trajectory of the rotation control pin 75 when it is made to do.

  Further, in the guide hole 84, the rotation restriction pin 75 is held by the attaching / detaching position side end portion 84a of the guiding hole 84 in the vicinity of the attaching / detaching position side end portion 84a, thereby holding the guide passage 64 at the attaching / detaching position. A projecting portion 85a is provided.

  When attaching the special symbol starting means 24 to the game board 13, as shown in FIG. 12, the guide path 64 is first rotated with respect to the mounting hole 13 a of the game board 13 with the guide path 64 rotated to the attachment / detachment position. The solenoid 65, the guide rod 63, and the like are housed in the mounting hole 13a while being inserted from the front side, and the back surface side of the main body 61 is brought into contact with the front surface of the game board 13 (FIG. 12A). Since the guide passage 64 is substantially straight in the front and rear direction with the guide rod 63 at the attachment / detachment position, the guide passage 64 can be easily inserted without interfering with the edge of the attachment hole 13a. At this time, since the protrusion 85a in the guide hole 84 restricts the movement of the rotation restricting pin 75 and the guide passage 64 is held at the attachment / detachment position, the guide passage 64 does not wobble and the operation can be performed more easily. Can do.

  Subsequently, the guide passage 64 is rotated approximately 90 degrees from the attachment / detachment position to the guide position (FIG. 12B), and the front edge 81a of the side plate 81 of the guide passage 64 is in contact with the back side of the game board 13. The guide passage 64 is slid downward along the back side of the game board 13 (FIGS. 12C and 12D). Thereby, the movement of the rotation restricting pin 75 in the front-rear direction is restricted, and the guide passage 64 is fixed at the guide position, so that the guide passage 64 can be prevented from swinging when the game ball is guided. In addition, since the guide passage 64 can be fixed in a state where the back side of the game board 13 is pressed, for example, when the special symbol starting means 24 is fixed to the game board 13 by a press-fit pin or the like, the fixed state is further stabilized. Can do.

  Further, the guide position holding means 95 of the present embodiment does not use a separate member such as the fixed lever 91, and the rotation shaft 74, the rotation restriction pin 75, the bearing hole 83, the guide shown in the first embodiment. Since the arrangement and shape of the holes 84 are slightly changed, the cost can be reduced.
