The moving mechanism includes a pair of left and right moving levers that are rotated in synchronization with the drive source in a bilaterally symmetric direction, and a left and right intermediate lever that is pivotally supported by the decorative body and is rotated by each moving lever. And a connecting rod connecting the left and right intermediate levers, and one intermediate lever is a pivot point for the decorative body between the connecting point with the moving lever and the connecting point with the connecting rod. The other intermediate lever is characterized in that the connecting point with the moving lever and the connecting point with the connecting rod are at an acute angle with the pivot point to the decorative body as the center. It is.

The drive source is composed of two drive sources, and the drive sources can be rotated synchronously by the control means.

In the first aspect of the invention, since the connecting rod restricts the free rotation of the two left and right intermediate levers, the decorative body can be moved by an approximate linear motion without swinging. One of the intermediate levers has a shaft fulcrum to the decorative body between the connecting point of the moving lever and the connecting point of the connecting rod, and the other intermediate lever is connected to the moving lever. Since the connecting point and the connecting point of the connecting rod are at an acute angle with the pivot point to the decorative body as the center, the swing of the decorative body can be restrained.
In the invention according to claim 2, since the two driving sources are operated in synchronization to rotate the tip of the moving lever, the tip of the balancing lever is rotated to move the decorative body linearly. it can.

It is the front view (a), the top view (b), and the side view (c) which show the engagement state of a motor and a moving arm. It is a front view of the movable decoration device in which the decorative body is in the middle of descending. It is a front view of the movable decoration device in a state where the decoration body is lowered. It is a conceptual diagram explaining the preferable position of a fulcrum.

Hereinafter, embodiments of the present invention will be described.
1 and 2 are diagrams showing a movable decorative device disposed on the upper part of the center case 1 that covers the periphery of the variable symbol display device of the gaming machine. The movable decorative device includes a motor 2 (stepping motor) as a drive source, a moving lever 3, an intermediate lever 4, a connecting rod 6, and a decorative body 5. In the state of FIG. 1, the decorative body 5 is raised and stored in the upper part of the center case 1. The motor 2 is screwed to the left and right attachment bases 11 of the decorative body 5. The decorative body 5 includes an LED substrate 51 and a back plate 52.

  The moving mechanism of the movable decorative device will be described with reference to FIG. The moving mechanism includes two motors 2, a pair of moving levers 3 a and 3 b that are respectively rotated by the two motors 2, and a pair of intermediate levers 4 a and 4 b that are pivotally attached to the left and right of the decorative body 5. The moving levers 3a and 3b are arranged symmetrically.

  The moving levers 3 a and 3 b are formed in an L shape and are pivotally attached to a support shaft 31 provided in the center case 1. One L-shaped short arm 32 is rotated by the motor 2. By the rotation of the short arm 32, the long arm 33 extending in the direction orthogonal to the short arm 32 is also rotated together. The shape of the moving lever 3 is not limited to the L-shape, and any shape can be used as long as the tip of the long arm 33 can rotate around the support shaft 31. A spring 7 is attached to the long arm 33 as an elastic body that biases the long arm 33 upward.

  Next, the intermediate lever 4 will be described. In the left intermediate lever 4b in the drawing, a force point side arm 42 extends from the fulcrum 41 in one direction, and an action point side arm 43 extends from the force point side arm 42 in a different direction over 90 °. When the force point side arm 42 moves to the left, the action point side arm 43 moves to the right, and when the force point side arm 42 moves to the right, the action point side arm 43 moves to the left. Because. The distal end of the moving lever 3 b is pivotally attached to the distal end of the power point side arm 42.

  Further, the right intermediate lever 4b has a force point side arm 46 extending in one direction from the fulcrum 45, and an action point side arm 47 extending in a different direction within a range of less than 90 ° from the force point side arm 46. Yes. The tip of the right moving lever 3 a is pivotally attached to the tip of the force point side arm 46. This is because when the force point side arm 46 moves to the left, the action point side arm 47 also moves to the left so that the movements are in the same direction. The tip of the right moving lever 3 a is pivotally attached to the tip of the force point side arm 46. The tips of the two action point side arms 43 and 47 are connected by a connecting rod 6.

A preferred positional relationship of the fulcrum 41 of the intermediate lever 4 with respect to the long arm 33 of the moving lever 3 will be described with reference to FIG. In FIG. 6, the tip of the long arm 33 descends in a circular arc from the point S ₁ through the point R to the point S ₂ around the support shaft 31. The tip of the long arm 33 moves in the horizontal direction by the distance between RS _{3 in the} figure. The power point side arm 46 of the intermediate lever 4 also descends with the lowering of the long arm 33, but the power point side arm 46 pivotally attached to the tip of the long arm 33 has the fulcrum 41 to absorb the horizontal movement distance of the RS _3. It needs to rotate around the center. Therefore, when the fulcrum 41 is on the straight line TT ₁ orthogonal to the _3-wire RS through an intermediate point T of RS _3, the tip of the force point side arm 46 by the same distance it swung right and left, long The positional shift due to the arc motion of the arm 33 can be absorbed. Therefore, it is necessary to provide the fulcrum 41 so as to be positioned on TT ₁ .

  The engagement state between the motor 2 and the moving lever 3 will be described with reference to FIG. A crankpin 22 is attached to the shaft 21 of the motor 2 so as to be eccentric to the shaft 21. A recess 35 is provided at the end of the short arm 32 of the moving lever 3, and the tip of the crank pin 22 is loosely fitted in the recess 35, and the crank pin 22 rotates the short arm 32. be able to. A position detection sensor 23 for the crank pin 22 is disposed in the vicinity of the shaft 21 of the motor 2, and a protrusion 24 for position detection is provided on the crank pin 22. The initial position of the crankpin 22 is detected by the projection piece 24 blocking the light emitted from the sensor 23 or the like.

  In the above-described configuration, when a special game state such as a jackpot is reached, the right motor 2 is driven and the right short arm 32 is rotated counterclockwise in the state of FIG. . As a result, the right long arm 33 is also rotated counterclockwise, and its tip is lowered downward. On the other hand, the short arm 32 on the left side is rotated clockwise and the tip of the long arm 33 is lowered downward, so that the decorative body 5 passes through the intermediate position shown in FIG. Will be lowered to the position. At the same time, the right balance lever 4 is also moved downward while being rotated counterclockwise.

  At this time, since the long arms 33 and 33 are rotated while drawing an arc, when the left and right intermediate levers 4a and 4b are in a free state, the decorative body 5 is moved through the force point side arms 42 and 46. Since it only hangs at the tips of 3a and 3b, the decorative body 5 can swing left and right. However, in the present invention, one working point side arm 47 is provided close to the power point side arm 46, and the other working point side arm 43 is provided so as to protrude substantially opposite to the fulcrum 41. When the two motors 2 are driven synchronously and rotated reversely so that the two force point side arms 42 and 46 are bilaterally symmetric, the two action point side arms 43 and 47 can be rotated in the same direction. Therefore, if the tips of the action point side arms 43 and 47 are connected by the connecting rod 6, the swinging of the decorative body 5 is restrained by the connecting rod 6, so that the decorative body 5 can be moved up and down without swinging. . Therefore, the ornamental body 5 can be moved downward along the straight line P perpendicular to the straight line connecting the left and right pivots 41.

  After the descent is completed, the left and right motors 2 and 2 are rotated in the reverse direction, so that the right moving lever 3a and the intermediate lever 4a rotate clockwise, and the left moving lever 3b and the intermediate lever 4 counterclockwise. It is rotated clockwise. Therefore, the decorative body 5 is returned to the initial position in FIG. 5 via the intermediate position shown in FIG. The above operation is repeated and the decorative body 5 is reciprocated along the straight line P by the approximate linear motion.

Although the example in which the decorative body is moved up and down has been described above, in the present invention, the movable decorative device can be attached horizontally or diagonally downward, and the decorative body can be moved in the lateral direction of the left or right or the diagonally upward and downward direction.
In the embodiment of the present invention, the pair of moving levers 3 are also operated in synchronism by rotating the two motors 2 as drive sources in synchronism with a control means (not shown). These two levers 3 can be operated in synchronism by mechanically transmitting the drive to the respective levers 3 for movement.
