Hereinafter, embodiments of the present invention will be described.
1-3 is a figure which shows the rotation display apparatus of this invention, Comprising: 1 is the rotary body on which information, such as a symbol and a character, was displayed. The player visually recognizes the information displayed on the rotating body 1 from the direction of arrow S in FIG. 1 through a window (not shown). The rotating body 1 has a concave upper portion, and a mounting plate portion 11 is formed at the bottom of the concave portion.

  The mounting plate portion 11 is screwed to the fixing member 12. An insertion hole 13 is formed in the fixing member 12, and the D-cut portion 14 of the first rotation shaft 2 that is inclined obliquely is inserted into the insertion hole 13, so that the first rotation shaft 2 is fixed to the fixing member 12. The first rotating shaft 2 can rotate together with the fixed member 12. Therefore, the rotating body 1 is rotated by the rotation of the first rotating shaft 2.

  The first rotating shaft 2 is inserted into the through hole 31 of the first support member 3. Since the bearings 32 are disposed at both ends of the through hole 31, the first rotary shaft 2 is supported by the first support member 3 so as to be rotatable about the axis P of the first rotary shaft 2. A driven gear 21 is fastened and fixed to the other end of the first rotating shaft 2 by a nut 23.

  The first support member 3 is fixed to the tip of the second rotating shaft 5 that is D-cut by a screw 51. Since the second rotating shaft 5 is directly connected to the rotating shaft 71 of the first motor 7, the first support member 3 rotates around the axis R of the second rotating shaft 5 (FIG. 1). Thereby, the rotating body 1 is also revolved around the second rotating shaft 5.

  In the bearing member 6, the second rotating shaft 5 is inserted into the insertion hole 61, and bearings 62 are disposed at both ends of the insertion hole 61. Therefore, the bearing member 6 is centered on the second rotating shaft 5. Rotate. A main driving gear 63 is fixed to the front end side of the bearing member 6 and meshes with the driven gear 21. An intermediate gear 64 is fixed to the base end side of the bearing member 6, and meshes with a drive gear 82 fixed to the rotating shaft 81 of the second motor 8. The main driving gear 63 and the driven gear 21 are bevel gears. Moreover, the 2nd rotating shaft 5 and the 1st rotating shaft 2 cross | intersect diagonally on the same plane.

  The second rotating shaft 5 has a rotating plate 52 on the base end side, and the rotating plate 52 is provided with a slit 53 for position detection. The intermediate gear 64 of the bearing member 6 is also provided with a rotating plate 65 and has a position detecting slit 66 (FIG. 3). Photosensors 73 and 83 are disposed in the vicinity of the rotary plates 52 and 65, respectively, and detect the slits 53 and 66 by the passage of light. The photosensors 73 and 83 shown in FIG. 3 are shifted in position to show the slits 53 and 66, but the photosensors 73 and 83 are arranged so as to sandwich the rotating plates 52 and 65.

  A bush 15 is fixed to the upper end of the first rotating shaft 2, and a first coil spring 16 is mounted between the bush 15 and the fixing member 12 (FIG. 2). Since the first coil spring 16 is pulled and mounted between them, the first rotating shaft 2 is urged upward, that is, in a direction in which the driven gear 21 is pressed against the main driving gear 63. Thereby, backlash can be minimized and rotation spots can be eliminated. The fixing member 12 is provided with a stopper 17 which is an elastic piece, and this stopper 17 has a locking claw 18. Thereby, the latching claw 18 can latch the flange of the bush 15 to prevent the first rotating shaft 2 from sliding in the driven gear 21 direction. Further, in a normal state where the driven gear 21 is pressed against the main driving gear 63 by the first coil spring 16, a slight gap is provided between the locking claw 18 and the bush 15 of the bush 15. The upper limit of the gap (= backlash) between the main driving gear 73 and the driven gear 21 can be regulated by the claw 18.

  A second coil spring 22 is mounted between the end portion of the first support member 3 and the driven gear 21 to urge the driven gear 21 downward, that is, in a direction away from the main driving gear 63. As a result, a preload can be applied to the ball bearings 32 and 32 for alignment. That is, since the load from the first coil spring 16 is mainly applied to the ball bearing 32 on the fixed member 12 side and the load from the second coil spring is applied to the ball bearing 32 on the driven gear 21 side, the two ball bearings 32 and 32 are applied. Is preloaded and aligned.

  In order to position the rotation start position of the rotating body 1, the elastic piece 17 is bent so that the locking claw 18 is retracted to a position where it cannot be engaged with the flange portion of the bush 15, and then the first rotating shaft 2 is moved downward. To release the meshing of the driven gear 21 with the main driving gear 63 as shown in FIG. As a result, the first rotating shaft 2 can freely rotate, so that the rotating body 1 can be rotated to position required information in front. At this time, the first coil spring 16 is compressed and the second coil spring 22 is returned.

  In the rotary display device configured as described above, when the first motor 7 is rotated, the second rotary shaft 5 is rotated, whereby the first support member 3 is rotated around the axis R. Are revolved together. Further, the drive gear 82 is driven by the operation of the second motor 8, and the driven gear 21 is rotated via the intermediate gear 64 and the main driving gear 63. As a result, the rotating body 1 rotates around the axis P of the first rotating shaft 2. The rotation and revolution are controlled by the photo sensors 73 and 83 detecting the slits 53 and 66. In the present invention, since the first rotating shaft 2 and the second rotating shaft 5 are driven by separate motors, the revolution of the rotating body 1 around the second rotating shaft 5 and the first rotating shaft 2 Rotating rotation can be performed independently according to the contents of the game.

  In the rotary display device as described above, since it is difficult to arrange a light source inside the hemispherical rotary body 1, a light source 91 such as an LED is provided below the rotary body 1 as shown in FIG. The provided illumination board 9 is disposed. Since the distance between the display screen (S-side surface) of the rotating body 1 and the light source 91 is long, a high-intensity light source 91 is required to clearly display information such as symbols drawn on the display screen. When the high-intensity light source 91 is used, light with high looks (high luminous flux divergence) of the light source 91 is projected onto the rotating body 1 or the shadows of the driving mechanisms such as the first support member 3 and the main driving gear 63 appear. It is projected and looks bad. Therefore, as shown in FIGS. 6 and 7, it is desirable to interpose a light diffusion plate 10 between the back side of the display screen of the rotating body 1 and the first support member 3. The light diffusing plate 10 is fixed to the tip of a protruding rod 33 provided on the first support member 3 with a screw. Accordingly, it is possible to prevent the appearance of the display screen from being deteriorated by receiving the light of the light source 91 or the shadow of the first support member 3 or the like. In addition, as the light diffusing plate 10, a light diffusing plate made of resin or the like having a fine unevenness formed by blasting or Fresnel lens processing on the surface or a light diffusing plate coated with a light diffusing agent can be used. A light diffusing agent is also applied to the inside of the rotating body 1.
