In the effect device for a ball game machine configured as described above, when the driving body rotates in one direction using the motor as a driving source, a driving protrusion protruding from the front surface of the driving body is provided on the back surface of the swing arm. Since the cam-like projections rotate and slide from the upstream side to the downstream side to press the swing arm, the rotation of the drive body is caused by the sliding of the drive projection and the cam-like projection. Converted into motion, the swing arm can be swung back and forth along a plane perpendicular to the board surface of the game board. At this time, since the upstream side of the cam-like protrusion has a gentler slope than the downstream side, the torque required when the drive protrusion starts to press the cam-like protrusion is small, and a small motor can be used. The swing arm can swing smoothly by rotating in either the forward or reverse direction. A pressing portion protruding forward is provided at the end opposite to the fulcrum of the swing arm, and this pressing portion elastically deforms the elastic deforming portion of the movable accessory along with the swinging motion of the swing arm. The effect of playing the game can be enhanced by swinging the elastically deforming portion of the movable accessory in the front-rear direction.

In the above configuration, the number of drive lugs is not particularly limited, if there are provided at predetermined intervals a plurality of drive protrusions along the direction of rotation of the drive member, a plurality of driving projections during one rotation of the drive member Since the cam-like protrusions are sequentially pressed, the swing arm can be swung in small increments by a single rotation of the drive body .

The effect device for a ball game machine according to the present invention is configured such that when a driving body having a driving protrusion rotates in one direction using a motor as a driving source, a driving protrusion protruding from the front surface of the driving body is provided on the back surface of the swing arm. In order to rotate and slide the outer surface of the cam-like projections to press the swing arm, the swing arm can be swung back and forth along a plane perpendicular to the board surface of the game board, since the upstream side of the cam-like projection is in gentle inclined surface as compared to the downstream side, the drive projection Ru can be reduced torque required when starting to push the cam-shaped protrusion. Therefore, the swing arm can smoothly swing by rotating a small motor in either the forward or reverse direction, and the elastically deforming portion of the movable accessory disposed in front of the swing arm can be moved in the front-rear direction. The effect of playing the game can be enhanced by swinging it in small increments.

As shown in FIG. 5, the first and second motors 23, 26 and the first and second gear trains 22, 25 described above are disposed on the back side of the decorative case 15, and the flat shape of the drive shaft 24. The first gear of the third gear train 27 is engaged with the gear 24b. The final gear 27a of the third gear train 27 is fixed to the back surface of the driving body 28 that is a constituent member of the swing unit 18, and the rotation of the second motor 26 is changed from the second gear train 25 to the third gear train 25. It is transmitted to the drive body 28 via the gear train 27. As is apparent from FIG. 8, the driving body 28 is rotatable about a direction orthogonal to the board surface of the game board 3 as a central axis, and the swing arm 19 is located between the movable accessory 10 and the driving body 28. It is arranged in an almost vertical posture.

  As shown in FIGS. 11 and 12, the swing unit 18 includes a support 29 attached to the decorative case 15 by means such as screwing, and a swing supported on the support 29 so as to be rotatable. The moving arm 19, the driving body 28 disposed on the back side of the swinging arm 19, and a coil spring 30 that elastically biases the swinging arm 19 toward the driving body 28. One end of the swing arm 19 is provided with a shaft hole 19a. By inserting the connecting pin 31 into the shaft hole 19a and the support 29, the swing arm 19 uses the connecting pin 31 as the swing center axis. The game board 3 can swing in the front-rear direction. Further, the swing arm 19 is formed with a spring hook portion 19b in the vicinity of the shaft hole 19a, and both ends of the coil spring 30 as a spring member are hooked to the support 29 and the spring hook portion 19b. Further, a pair of columnar pressing portions 19c are erected at the end of the swing arm 19 opposite to the shaft hole 19a, and the tips of these pressing portions 19c are formed in a hemispherical surface. As shown in FIG. 8, the swing arm 19 is disposed between the accessory body 16 and the decorative case 15, and both pressing portions 19 c are inserted into the accessory body 16, Opposite.

  As shown in FIGS. 13 and 14, a cam-like protrusion 32 is provided on the back surface of the swing arm 19, and the drive body 28 has a plurality of drive protrusions that slide on the outer surface of the cam-like protrusion 32. 28a is provided. The drive protrusions 28a are arranged at equal intervals along the rotation direction of the drive body 28. In the case of this embodiment, the four drive protrusions 28a are spaced by 90 degrees along the rotation direction of the drive body 28. Is arranged. Therefore, when the drive body 28 rotates in one direction (the arrow direction in FIG. 11) using the second motor 26 as a drive source, the four drive protrusions 28a are formed on the outer surface of the cam-like protrusion 32 during one rotation of the drive body 28. Are sequentially slid from the upstream side toward the downstream side, and accordingly, the swing arm 19 swings in the longitudinal direction of the game board 3 in small increments. That is, in the process in which one drive projection 28 a slides on the outer surface of the cam-like projection 32 from the upstream side toward the center portion, the swing arm 19 presses forward against the elastic biasing force of the coil spring 30. In the process in which the drive protrusion 28a passes through the central portion of the cam-like protrusion 32 and moves toward the downstream side, the swing arm 19 receives the elastic biasing force of the coil spring 30 and swings back. By repeating the operation by the plurality of drive protrusions 28a, the swing arm 19 swings in the forward and backward directions.

  Thus, the drive protrusion 28a slides on the outer surface of the cam-like protrusion 32 from the upstream side toward the downstream side, so that the rotational movement of the drive body 28 is caused by the sliding portion of the drive protrusion 28a and the cam-like protrusion 32. However, as shown in FIG. 15, the outer surface of the cam-like protrusion 32 is set so that the upstream side 32a has a gentler slope than the downstream side 32b. Has been. As a result, the torque required when the drive protrusion 28a starts to press the cam-like protrusion 32 can be reduced, and the swing arm 19 can be smoothly swung even if an inexpensive and small second motor 26 is used as a drive source. Can move. Further, since the cam-like protrusion 32 is pressed against the drive protrusion 28a by the elastic biasing force of the coil spring 30, a reliable swing operation can be realized even if the swing arm 19 is reduced in weight, and the player can play the game board. Even if a large impact force is generated by hitting 3 or the like, it is possible to prevent the swing arm 19 from swinging carelessly due to the impact force.

  In the effect device for a ball game machine according to the present embodiment, when a game ball wins the start winning slot 11, a lottery is drawn by a random number generator stored in a control unit (not shown). Based on the result, the first and second motors 23 and 26 are started to operate the movable accessory 10, thereby enhancing the effect of playing the game by associating the display content of the liquid crystal panel 9 with the movement of the movable accessory 10. It is supposed to be. In this case, when the first motor 23 is first started and rotated in one direction, the rotation is transmitted from the first gear train 22 to the oscillating body 20 via the sector gear 20c. It rotates in front of the accessory body 16 with the shaft 20b as the center of oscillation. As a result, the entire composite movable portion 17 including the swinging body 20 and the rotating body 21 swings and rotates from the standby position shown in FIG. 3 to the arrow P and moves to the operating position shown in FIG. The 16 arm portions 16 b are also rotationally displaced in conjunction with the movement of the rocking body 20.

  If the first motor 23 is stopped when the composite movable portion 17 moves to the operating position of FIG. In this state, when the second motor 26 is started and rotated in one direction, the rotation is transmitted from the second gear train 25 to the rotating body 21 via the drive shaft 24, so that the rotating body 21 is a liquid crystal panel. It rotates continuously in front of 9. Further, since the rotation of the second motor 26 is transmitted from the second gear train 25 to the drive body 28 of the swing unit 18 via the third gear train 27, the drive body 28 transmits the second motor 26. As a drive source, the drive projection 28a of the drive body 28 starts to rotate continuously in the direction of the arrow in FIG. To do. At that time, in the process in which the driving projection 28a slides on the outer surface of the cam-like projection 32 from the upstream side toward the center portion, the swing arm 19 is pressed forward against the elastic biasing force of the coil spring 30. In the process in which the drive protrusion 28a passes through the central portion of the cam-like protrusion 32 and moves toward the downstream side, the swinging arm 19 receives the elastic biasing force of the coil spring 30 and returns to swing backward. With the continuous rotation, the swing arm 19 swings in the longitudinal direction of the game board 3 in small increments, and the elastic deformation portion 16a of the accessory body 16 is moved by the pressing portion 19c provided upright on the swing arm 19. Elastically deformed. In this way, when the composite movable portion 17 is in the operating position of FIG. 6, the elastic deforming portion 16 a of the accessory body 16 is elastically deformed in small increments while continuously rotating the rotating body 21. It is possible to express how a person holding a fired fire while rotating the barrel.

  Further, when the rotation of the second motor 26 is stopped and then the first motor 23 is rotated in the opposite direction, the composite movable portion 17 swings and rotates from the operating position of FIG. Return to the standby position. Also in this case, since the rotation of the second motor 26 is transmitted from the first gear train 22 to the oscillating body 20 via the sector gear 20c, the oscillating body 20 has the hollow shaft 20b as the oscillating center and the accessory body 16 Rotate in front of.

  In the effect device for the ball game machine according to the present embodiment configured as described above, the cam-like protrusion for converting the rotation operation of the driving body 28 into the swing operation of the swing arm 19 on the back surface of the swing arm 19. When the driving body 28 rotates in one direction using the second motor 26 as a driving source, the driving protrusion 28a provided on the driving body 28 slides on the outer surface of the cam-like protrusion 32 and swings. Since the moving arm 19 is pressed, the swinging arm 19 can be swung in the front-rear direction of the game board 3, and the upstream side 32a and the downstream side 32b of the outer surface of the cam-like protrusion 32 are provided. Therefore, the torque required when the drive protrusion 28a starts to press the cam-like protrusion 32 can be reduced. Therefore, the swing arm 19 can be smoothly swung using the inexpensive and small second motor 26 as a drive source, and is interposed between the second motor 26 and the drive body 28. It is possible to prevent the gears of the second and third gear trains 25 and 27 from being locally worn.

  Further, the drive body 28 is provided with a plurality of drive projections 28a with a predetermined interval in the rotation direction, and the cam-like projections 32 of the swing arm 19 are pressed against these drive projections 28a. The swing arm 19 can be swung a plurality of times in one rotation, and the swing arm 19 can be swung in the front-rear direction of the game board 3 in small increments. Further, the pressing portion 19c is erected on the swing arm 19, and the tip of the pressing portion 19c formed in a spherical shape is opposed to the back surface of the elastic deforming portion 16a of the accessory body 16, thereby swinging the elastic deforming portion 16a. Since elastic deformation is performed in accordance with the swinging motion of the moving arm 19, damage to the elastic deformation portion 16a can be suppressed.

  In the above embodiment, the case where the drive body 28 is provided with the four drive protrusions 28a every 90 degrees has been described. However, for example, the three drive protrusions 28a are disposed every 120 degrees, and the drive protrusions 28a are arranged. The number can be increased or decreased as needed.
