  The present invention relates to a ball game machine that is installed and used in a game hall such as a pachinko parlor, and in particular, a ball ball equipped with a movable accessory device capable of suggesting or notifying a player of an electronic lottery result. It relates to gaming machines.

  In some ball game machines represented by pachinko machines, an effect display device and a start winning opening are provided in the game area of the game board, and the game balls launched toward the game area have won the start winning opening. There is a model in which an electronic lottery is performed as a trigger, and an effect display device displays a symbol change display and a stop display based on the lottery result. Electronic lottery results include winning (winning) and losing (non-winning). When the lottery result is winning, a combination of predetermined special symbols is displayed on the display screen of the production display device, and the gaming state is normal. Transition from mode to special game mode. In this special game mode, for example, the game ball enters the big prize opening exposed by opening the attacker, so that the player can acquire many prize balls.

  In such a ball game machine, the display screen of the effect display device is exposed in the opening of the decoration case disposed in the center of the game area, and the movable body imitating various characters is appropriately positioned on the decoration case. The movable accessory device is widely adopted, which is suggested or notified to the player by the movable mode of the movable body, and is arranged at the top of the decorative case as an example. A movable accessory device is known in which a movable body that is moved up and down is moved in and out of the effect display device (see, for example, Patent Document 1). Such a movable accessory device includes a pair of drive arms that rotate synchronously in opposite directions using a first motor as a drive source, a movable body that moves up and down between a raised position and a lowered position by rotation of these drive arms, And a stopper member for preventing the movable body in the raised position from dropping, and the stopper member reciprocates in the left-right direction using the second motor as a drive source.

  In the bullet ball game machine having the movable accessory device schematically configured as described above, when the movable body is stopped at the initial position above the effect display device, the stopper member moves to one end side in the left-right direction and is movable. By engaging with the upper part of the body, the movable body is stably held at the raised position and prevented from falling. In this state, the stopper member is moved to the other end side by driving the second motor to release the locking between the stopper member and the movable body, and the crossing angle of the two driving arms is changed by the driving of the first motor. If it rotates so that it may narrow, a movable body will fall from a raise position and will stop in the descent position ahead of an effect display device. Further, when the first motor is driven in the reverse direction when the movable body is in the lowered position, the crossing angle of both drive arms gradually increases, so that the movable body moves from the lowered position toward the upper side of the effect display device. Moving. When the second motor is driven to move the stopper member to the one end side when the movable body moves to the raised position, the stopper member is again locked to the upper portion of the movable body, so that the movable body falls. It is stably held at the initial position in the blocked state.

In addition, the movable body 37 is hidden behind the upper wall of the decorative case 22 and does not appear on the display screen 24 a of the effect display device 24. Here, first, the raising / lowering operation of the movable body 37 will be described with reference to FIGS. 4 to 7. As shown in FIGS. 4 and 5, in the initial position, the vicinity of the tip portions of the left and right arms 38 is respectively a stopper protrusion. In addition, the long holes 41 formed in the left and right rotating plates 36 are in positions opposite to the movable body 37 via the rotation center O (shaft 40) of the rotating plate 36. The drive pins 43 provided at the distal end portions of the arms 38 are positioned below the straight line L (see FIG. 5) connecting the connecting portion 38b (support shaft 44) and the rotation center O of the rotating plate 36. Engage with the inner end. Therefore, the weight of the movable body 37 connected to the connecting portion 38b of the both arms 38 is received by the stopper projection 39, and the weight is increased by mounting the rotary decorative body 50 including the convex lens 58 group, the motor 48 as a driving source thereof, and the like. In spite of the large movable body 37, the movable body 37 can be surely stopped at the initial position above the effect display device 24. When the movable body 37 is held at the initial position in this way, the boss 33a protruding from the base body 33 is located in a bowl-shaped escape portion 38a formed on the tip side of both arms 38, By this escape portion 38 a, contact between the boss 33 a that is a bearing portion of the rotating plate 36 and the tip portion of the arm 38 having the drive pin 43 is avoided.

  In this state, the left and right motors 35 are started to rotate the right rotating plate 36 in the counterclockwise direction in FIG. 4 and the left rotating plate 36 in the clockwise direction in FIG. The rotational motion is transmitted to the left and right arms 38 via the drive pins 43 engaged with the long holes 41, and these arms 38 move downward together with the movable body 37 so as to gradually narrow the crossing angle with each other. The movable body 37 held at the position is lowered from the intermediate state of FIGS. 4 to 6 to the operation position shown in FIG. At that time, the posture of the long hole 41 (the direction of the long axis) changes according to the rotation angle of the rotary plate 36, and while the left and right rotary plates 36 are rotated from the angle shown in FIGS. Is changed from a tilted posture to a vertical posture (see FIG. 6), and then tilted in the opposite direction to a tilted posture (see FIG. 7) through a horizontal posture. To the outer edge. When the motor 35 is stopped when the movable body 37 is lowered to the operating position shown in FIG. 7, the movable body 37 suspended from the left and right arms 38 is removed from the upper wall of the decorative case 22 as shown in FIG.

However, the movable body 37 returns to the initial position again and is hidden behind the upper wall of the decorative case 22 as shown in FIG. Specifically, when the right rotating plate 36 is rotationally driven in the clockwise direction in FIG. 7 and the left rotating plate 36 is rotationally driven in the counterclockwise direction in FIG. 7, first, the outer end portion is inclined downward. Since the posture of the long hole 41 gradually approaches the vertical state, both arms 38 move in the rotation direction of the rotating plate 36 while the drive pins 43 are engaged with the outer end portions of the long holes 41 during this time. Both arms 38 move in the upper space while avoiding contact with the stopper projections 39. Then, when the rotary plate 36 is rotationally driven to an angle at which the long hole 41 becomes a vertical posture, as shown in FIG. 6, the drive pin 43 that has been engaged with the outer end until then falls in the long hole 41. Both arms 38 abruptly approach the stopper projections 39 because they head toward the inner end. Further, when the rotating plate 36 is driven to rotate and the motor 35 is stopped when the inner end of the long hole 41 exceeds the straight line L (see FIG. 5), as shown in FIG. The vicinity is in contact with the upper surface of the stopper protrusion 39, and the movable body 37 is stably held at the initial position above the effect display device 24.

  Note that when the movable body 37 moves up and down in front of the display screen 24a, the left and right arms 38 move up and down together with the movable body 37 while changing the crossing angle with each other, but the two arms 38 connected to the movable body 37 are connected. Since the portions 38b are always meshed with each other via the gear 46 and the relay gear 47, the movable body 37 that is moving up and down does not tilt or fluctuate undesirably, and the movable body 37 is moved up and down in a stable posture without backlash. Can be made.

  Next, the light emission operation of the movable body 37 will be described with reference to FIGS. 8 to 10. When the movable body 37 of the movable accessory device 23 appears in front of the display screen 24a as shown in FIG. In addition, when the rotating decorative body 50 is rotationally driven in a state where the LEDs 55 on the first circuit board 49 are lit, light that is dimmed strongly or weakly can be emitted from the rotating decorative body 50 that is rotating. That is, when the motor 48 is started and the rotating decorative body 50 is rotationally driven in front of the first circuit board 49, the light of the LED 55 mounted on the first circuit board 49 rotates, and the convex decorative light transmission of the rotating decorative body 50 is achieved. The portion 50a (convex lens 58) and the flat light transmitting portion 50b are alternately transmitted and emitted forward. At this time, the light emitted from the LED 55 and directed to the flat light transmitting portion 50b is emitted as it is, but the light directed to the convex lens-shaped light transmitting portion 50a is converged light and emitted forward. Thus, an analog light emission form in which light intensity adjusted from the rotating decorative body 50 is emitted, and a novel and impactful lighting effect can be performed.

  In addition, when each LED 62 mounted on the second circuit board 52 is turned on, the light of these LEDs 62 is transmitted forward through the front plate 60 and the outer peripheral plate 61 of the design member 51, and thus the rotating decorative body 50. It is possible to illuminate the design member 51 disposed in the central portion of the. In particular, when the LED 55 on the first circuit board 49 and the LED 62 on the second circuit board 52 are turned on at the same time, the lighting device 50 emits light while rotating around the design member 51 to be illuminated. Production can be performed.

  As described above, in the ball game machine (pachinko machine) according to this embodiment, the movable accessory device 23 arranged on the back side of the upper wall of the decorative case 22 is fixed to the interior of the decorative case 22. 33, a pair of left and right rotating plates 36 having a long hole 41, a motor 35 that rotationally drives both rotating plates 36 in both forward and reverse directions, and a drive pin 43 provided on one end side are slidably engaged with the long hole 41. A pair of left and right arms 38 and a movable body 37 connected to the other end of both arms 38 are provided. When the left and right rotating plates 36 rotate in opposite directions with the motor 35 as a drive source, The rotational movement of the rotary plate 36 is transmitted to the left and right arms 38 via the drive pins 43 engaged with the long holes 41, and the crossing angle of both arms 38 changes according to the rotational angle of both rotary plates 36. Along with it, the movable body 37 is staged. It can be moved up and down in front of the apparatus 24. In addition, a pair of left and right stopper protrusions 39 are provided on the base body 33, and both the arms 38 are brought into contact with the corresponding stopper protrusions 39, whereby the movable body 37 is stopped at the initial position above the effect display device 24, and both rotations are performed. The drive pin 43 moves in the longitudinal direction in the long hole 41 as the plate 36 rotates, so that the contact between the arm 38 and the stopper projection 39 is avoided during the raising / lowering operation of the movable body 37. The movable body 37 that moves up and down can be reliably held at the initial position above the effect display device 24 by a simple stopper structure.

  The rotary plate 36 is rotatably supported by a boss 33a projecting from the base body 33, and a hook-shaped escape portion 38a is formed at one end of an arm 38 having a drive pin 43. When the movable body 37 is held at the initial position, the contact of the boss 33a, which is the bearing portion of the rotating plate 36, and one end of the arm 38 is avoided by the escape portion 38a. One end portion of the rotating plate 36 can be compactly arranged in the space on the back side of the rotating plate 36.

  Further, the stopper projection 39 is provided at a position facing the back surface of the rotating plate 36, and when the movable body 37 is stopped at the lowest position (operating position) in front of the effect display device 24, one end of the arm 38 is provided. Since the position of the movable body 37 is regulated so that the movable body 37 is not lowered any further by contacting the portion with the stopper projection 39, the movable body 37 is moved to the upper and lower two positions (initial position and operating position) using one stopper projection 39. ) Can be stopped reliably. However, the operating position of the movable body 37 can be defined by a stopper mechanism different from the stopper protrusion 39.

  Further, since the gears 46 are respectively attached to the connecting portions 38b on the other end sides of the left and right arms 38, and the gears 46 and the relay gear 47 are always meshed with each other, the arms 38 are movable while changing the crossing angle with each other. When moving up and down together with the movable body 37, the movable body 37 that is moving up and down is not undesirably tilted or fluttered, and the movable body 37 can be moved up and down in a stable posture without backlash. Since the gears 46 attached to the connecting portions 38b of the arms 38 only need to rotate synchronously in the opposite directions, the relay gear 47 may be omitted and the gears 46 may be directly meshed with each other, or 2 N powers. The intermediate gear 47 may be interposed between the two gears 46.
