  As shown in FIGS. 4 to 12, the movable accessory device 13 according to the embodiment of the present invention includes a base member 24 fixed to the upper inner wall of the decorative case 12, and a motor 25 attached to the base member 24. A driving body 26 that rotates using the motor 25 as a driving source, a photo interrupter 27 that detects the origin position of the driving body 26, a rotating arm 28 that is swingably supported by the base member 24, and a rotating arm 28 It is mainly configured by a metal plate bracket 29 that is rotatably connected to the distal end portion, and an accessory body 30 that is fixed to the bracket 29.

  The motor 25 is laminated and integrated with the reduction gear unit 31, and the output shaft 31 a of the reduction gear unit 31 protrudes in a direction orthogonal to the board surface of the game board 3. A drive body 26 is fixed to the output shaft 31a, and the drive body 26 rotates about the output shaft 31a as the rotation center axis O. The driving body 26 is formed with a protrusion 26a and a detection piece 26b, and the axial direction of the protrusion 26a and the rotation center axis O are set parallel to each other. Therefore, when the driving body 26 rotates using the motor 25 as a driving source, the protrusion 26a rotates on a virtual circle P (two-dot chain line in FIG. 12) centering on the rotation center axis O. The detection piece 26 b protrudes radially outward from the rotation center axis O, and the detection piece 26 b rotates in a plane parallel to the board surface of the game board 3. The photo interrupter 27 is an optical sensor having a concave groove 27a, and a light emitting element and a light receiving element (not shown) are arranged to face each other through the concave groove 27a. The photo interrupter 27 is attached to the base member 24 via the base 32, and the tip of the detection piece 26b rotates so as to cross the concave groove 27a.

  The rotating arm 28 is a synthetic resin molded product having a pair of arm portions 28 a and 28 b extending in a substantially orthogonal direction, and the central portion thereof is supported by a support shaft 33 implanted in the base member 24 so as to be swingable. ing. The axial direction of the support shaft 33 and the rotation center axis O of the drive body 26 are also set parallel to each other. As shown in FIG. 12, assuming that the vertical line passing through the support shaft 33 is L, the rotation center axis of the drive body 26 O is located on the vertical line L. A cylindrical boss 28c projects from the tip of one arm 28a of the rotating arm 28, and this boss 28c is inserted into a horizontally long connecting groove 29a provided on the back of the upper end of the bracket 29. (See FIG. 5). A pair of rib-like projections 28d and 28e are formed on the back surface of the other arm portion 28b of the rotating arm 28, and a guide groove 34 is defined between the rib-like projections 28d and 28e. The guide groove 34 extends linearly from the support shaft 33, which is the rotation center of the rotation arm 28, radially outward, and the detailed operation will be described later. Moves in and out of the guide groove 34. The guide groove 34 is open at both ends in the longitudinal direction, and the opening closer to the support shaft 33 is the entrance / exit 34a of the projection 26a.

  The bracket 29 is formed with a plurality of elongated holes 29b extending in the vertical direction. The elongated holes 29b are engaged with a guide washer 35 fixed to the base member 24 in a state of being prevented from coming off. Accordingly, when the rotating arm 28 swings and rotates about the support shaft 33, the bracket 29 and the accessory body 30 move integrally in the vertical direction while being suspended from the rotating arm 28, and the elongated holes 29b. The guide washer 35 constitutes guide means for guiding the accessory body 30 in the vertical direction between the uppermost position and the lowermost position.

  The accessory body 30 is a hollow structure having a horizontally long box shape as a whole, and is molded using a light-transmitting synthetic resin. The accessory body 30 is fixed to the lower end of the bracket 29, and the front face is decorated with a logo type or the like. Although not shown, a circuit board on which a large number of LEDs are mounted is housed in the accessory body 30, and the circuit board and the relay board 36 attached to the base member 24 are connected via an FPC. Has been. The motor 25 and the relay board 36 are connected to a control board (not shown) disposed on the back side of the game board 3 via a wire harness, and based on a control signal output from the control board. The direction and amount of rotation of the motor 25 are controlled, and the LED on the circuit board is turned on. The photo interrupter 27 is also connected to the control board via a wire harness, and the origin position of the driving body 26 is detected when the output signal of the photo interrupter 27 is taken into the control board.

  Next, operation | movement of the movable accessory apparatus 13 comprised in this way is demonstrated.

  In the movable accessory device 13 according to the present embodiment, the accessory main body 30 is normally lifted to the uppermost position shown in FIGS. 4 to 8. When this position is called a home position, as shown in FIG. The accessory body 30 is held above the display screen 14a of the variable display device 14 at the home position. In this case, as shown in FIG. 12A, the protrusion 26a of the driving body 26 is engaged with the guide groove 34 of the rotating arm 28 on the left side of the vertical line L, and the rotating arm 28 is the accessory body. It is stopped with 30 being lifted to the uppermost position. Further, the detection piece 26b of the driving body 26 is located in the concave groove 27a of the photo interrupter 27 on the vertical line L, and the optical path from the light emitting element to the light receiving element of the photo interrupter 27 is blocked by the detection piece 26b. Therefore, based on the output signal of the photo interrupter 27, it can be detected that the driving body 26 is at the origin position.

  When the motor 25 is rotated in one direction (clockwise direction in FIG. 12) when the accessory body 30 is in the home position as described above, the drive body 26 is rotated in the same direction using the motor 25 as a drive source. The protrusion 26 a rotates on the virtual circle P toward the entrance / exit 34 a of the guide groove 34. Then, when the projection 26a rotates to a position where it is disengaged from the entrance / exit 34a of the guide groove 34, as shown in FIG. 12 (b), the rotating arm 28 swings in the counterclockwise direction in FIG. To rotate, the bracket 29 connected to the tip of the pivot arm 28 moves downward while being guided by the engaging portion of the long hole 29b and the guide washer 35, and the upper end of the long hole 29b contacts the guide washer 35. At the time of contact, the bracket 29 stops. As a result, the accessory main body 30 suspended from the tip of the rotating arm 28 via the bracket 29 falls down vigorously, and the accessory main body 30 is held at the lowest position shown in FIG. That is, the accessory body 30 held above the display screen 14a at the home position vigorously drops by a predetermined amount in front of the display screen 14a, stops at the lowest position shown in FIG. 3, and is displayed at the position. It will be exposed in the upper area of the screen 14a. When the accessory body 30 is at an arbitrary position including the uppermost position and the lowermost position, for example, when the accessory body 30 is being dropped or stopped at the lowest position, the aforementioned LED is turned on or blinked. Accordingly, it is possible to perform a lighting effect in which the light of the LED is emitted from the front surface of the accessory body 30 that is dropped.

  Here, when the accessory body 30 is stopped at the lowest position, the turning arm 28 swinging and rotating counterclockwise is stopped at the standby position shown in FIG. The guide groove 34 moves to the right side of the vertical line L and positions the entrance / exit 34a on the virtual circle P. Accordingly, when the motor 25 is rotated in the clockwise direction while the accessory body 30 is stopped at the lowest position, the protrusion 26a of the driving body 26 rotates in the same direction on the virtual circle P, so that the guide groove extends from the doorway 34a. 34, the protrusion 26a and the guide groove 34 are engaged again. When the motor 25 is further rotated in the clockwise direction in this state, the protrusion 26a rotating on the virtual circle P moves in the guide groove 34, so that the rotating arm 28 is pivoted as shown in FIG. The bracket 29 and the accessory body 30 are raised from the lowest position along with the pivoting rotation in the clockwise direction of FIG. When the detection piece 26b enters the concave groove 27a of the photo interrupter 27, a signal for detecting the origin position of the driving body 26 is output from the photo interrupter 27, and when the rotation of the motor 25 is stopped based on this detection signal, The accessory body 30 is lifted to the uppermost position shown in FIGS. 4 to 8 and returned to the home position.

  When the accessory body 30 is raised from the lowermost position toward the uppermost position, that is, when the protrusion 26a and the guide groove 34 are in the engaged state shown in FIG. 12C, the motor 25 is moved in both forward and reverse directions. When the reciprocating rotation is performed by a minute angle, the accessory body 30 can be swung in small increments at an arbitrary position between the lowermost position and the uppermost position. Such a swinging action of the accessory body 30 and the above-described up-and-down movement described above are performed as a special symbol display when the game ball wins one of the first and second start winning ports 17 and 18. Depending on the result of the electronic lottery, it can be operated alone or in combination. For example, after superbly dropping the main body 30 onto the upper area of the display screen 14a, it is slowly raised to the home position (uppermost position), or is shaken in the middle of the ascent. It is designed to give variations to the movable aspect of the accessory body 30 such as returning from the home position to the home position, and the player plays a game while being throbbing that there is a high possibility of being a big hit depending on the movable aspect. I can enjoy it.

  As described above, in the movable accessory device 13 according to this embodiment, when the protrusion 26a of the driving body 26 that rotates using the motor 25 as the driving source is in the guide groove 34 of the rotating arm 28, the driving body 26 Since the rotation is transmitted to the rotating arm 28 through the engagement of the protrusion 26 a and the guide groove 34, the accessory body 30 is moved between the lowermost position and the uppermost position in conjunction with the swinging rotation of the rotating arm 28. Can be moved up and down. Further, when the driving body 26 is rotated in one direction until the protrusion 26a is disengaged from the guide groove 34, the rotating arm 28 swings and rotates in a direction away from the protrusion 26a due to the weight of the accessory body 30, so that it is lifted to the uppermost position. It is possible to vigorously drop the accessory body 30 that has been placed toward the lowest position. At this time, the rotating arm 28 stops at the standby position, and the entrance / exit 34a of the guide groove 34 is positioned on the rotation locus (virtual circle P) of the protrusion 26a, and the protrusion is caused by further rotation of the driving body 26 in the same direction. 26a can enter the guide groove 34 through the entrance / exit 34a, so that the accessory body 30 dropped to the lowest position in conjunction with the rotation of the rotary arm 28 can be raised to the uppermost position. That is, while the driving body 26 rotates 360 degrees (one rotation) from the origin position using the motor 25 as a driving source, the accessory main body 30 held at the home position above the display screen 14a is vigorously dropped to display the display screen. After the exposure in the upper region of 14a, the accessory body 30 can be raised to the home position again, and the accessory body 30 can be moved up and down with impact using one motor 25. .

  Further, the rotating arm 28 has a pair of arm portions 28a and 28b extending in a substantially orthogonal direction with the support shaft 33 as a center, and a bracket 29 integrated with the accessory body 30 is formed at the distal end portion of the one arm portion 28a. The guide groove 34 is formed in the other arm portion 28b, and the rotation center axis O of the driving body 26 is positioned on the vertical line L passing through the support shaft 33. Since it is set, the power transmission mechanism from the motor 26 to the accessory body 30 can be made into a compact structure as a whole. Further, the driving body 26 is provided with a detection piece 26b projecting radially outward, and the photo interrupter (light sensor) 27 capable of detecting the rotational position of the detection piece 26b is disposed on the base member 24. The detection structure for detecting the origin position can be simplified.
