DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the embodiments shown in FIGS. In the figure, reference numeral 1 denotes a display device. The display device 1 includes a driving body 2, a gear body 3, a rotating support 4, a rotating shaft 5, and a polyhedron 6 as shown in FIG. The gear body 3 is fixedly fixed to a fixed plate 7 as shown in the figure. In the illustrated embodiment, the gear body 3 is mounted and fixed on the fixed plate 7, and through a through hole 70 of the fixed plate 7. The driving body 2 is disposed below. On the upper surface side of the gear body 3, a rotating support 4 having a base 40 in a disk shape is disposed, and a shaft 41 that hangs down from the center of the back surface of the base 40 and is located on the central axis of the rotating support 4, It protrudes to below the driving body 2 through the through hole 30 located on the central axis of the gear body 3 and the driving body 2. When the driving force of the driving body 2 is transmitted to the shaft 41, the rotation support 4
Are provided so as to rotate about a central axis that is coaxial with the central axis of the gear body 3.

A cam 42 is provided at the lower end of the shaft 41 of the rotary support 4. The limit switch 8 contacts the rotating cam 42, and the rotation of the cam 42 is detected by the limit switch 8. The output of the controller 9 is described later.
Thus, the rotation speed and the rotation angle of the rotation support 4 can be detected. As shown in the drawing, a support portion 43 for rotatably supporting the rotation support shaft 5 is provided on a side portion of the base portion 40 of the rotation support member 4.
Are supported so that the center axis of the rotation support shaft 5 is inclined from the side of the gear body 3 so as to cross the center axis.

The rotation support shaft 5 rotatably supported by the support portion 43 of the rotation support member 4 has a tooth portion 31 on the outer peripheral edge of the gear body 3.
The rotation support shaft 5 is provided so as to rotate when the rotation support member 4 rotates. In the illustrated embodiment, a gear 50 is arranged at one end of the rotating shaft 5, and the gear 50 is engaged with the tooth 31. In the embodiment, the gear 50 and the teeth 31 are directly engaged with each other. However, the rotating shaft 5 may be rotated in the reverse direction with another gear 51 interposed therebetween (FIG. 2). The rotation support shaft 5 that rotates around the shaft is provided with the rotation support shaft 5.
The polyhedron 6 is attached so that the intersection of the central axis of the gear body 3 and the central axis of the gear body 3 becomes the center. The polyhedron 6 is a cube, and the rotation support shaft 5 is inserted in a direction from one corner to a corner diagonally located therefrom, and between the corner and a diagonally located corner. Is provided on the center axis of the gear body 3 as described above. The inclination of the rotation support shaft 5 is set to approximately 35 ° (when the center axis of the gear body is set in the vertical direction). That is, although the polyhedron 6 is rotated by the rotation of the rotation support shaft 5,
In one stop state of the polyhedron 6, the upper surface and the lower surface are arranged orthogonal to the center axis of the gear body 3, and the side surface is parallel to the center axis. It is provided so that it may be arranged. Each surface of the polyhedron 6 is configured as a display surface, and is provided with a code, a pattern, and the like.

In the display device 1 having the above structure, when the rotation support 4 rotates about the central axis of the gear body 3 by the driving body 2, the rotation support shaft 5 is connected to the central axis of the rotation support shaft 5 and the gear body. The gear 3 moves around the central axis of the gear body 3 with a point of intersection with the central axis as a fixed point, and rotates with the gear body 3 by meshing therewith. The polyhedron 6 rotates around the central axis of the gear body 3 by the movement of the rotation support shaft 5 (movement around the center axis of the gear body 3), and the rotation of the rotation support shaft 5 by the rotation of the rotation support shaft 5. When the polyhedron 6 is viewed from a certain direction, the plane appearing in the observation direction changes due to the rotation of the polyhedron itself.

The number of teeth of the tooth portion 31 of the gear body 3 and the number of teeth of the gear 50 meshing with the tooth portion 31 pass through a position where each surface of the rotating polyhedron 6 is in a frontal state with respect to the observation direction without inclination. Is set in advance. For example, shaft 4
When the rotation support shaft 5 is rotated by 120 ° when 1 rotates by 90 °, each surface A,
B, C, D, E and F are calculated as follows every time the shaft 41 advances by 90 °.
A → E → F → B → C → D → E → A → B → F → D → C → A
→ (Hereinafter, this is repeated).
And, the surface of the polyhedron 6 is placed in a front state in the observation direction by the operation control of the driving body 2 for rotating the shaft 41, and the shaft 41 is provided so that the shaft 41 can be stopped.
Every time a stop signal is input from the outside, the control unit 9 that controls the operation of the driving body 2 adjusts the rotation state of the shaft body 41 calculated from the detection information from the limit switch 8 and the operation information set in advance. Based on this, each surface of the polyhedron is provided so as to stop in the observation direction in a specific pattern or a random pattern and to display characters, patterns, and the like described on the surface. Also, other detection means may be used in place of the limit switch, or the driving body itself detects information such as the number of rotations, the rotation angle, and the rotation speed and sends the information to the control unit, and according to the control information from the control unit, This driver may be operated.

In the above-described embodiment, the polyhedron 6 is a cube, but the present invention is not limited to this. The number of teeth of the gear body and the number of teeth of the gear on the rotating shaft are determined according to the shape of the polyhedron. By making a selection, the surface of the polyhedron can be displayed in a state in front of the viewing direction.

In this game machine 10, the front side is used as an observation surface, and the display device 1 is installed in the game machine 10 so that the polyhedron 6 can be seen from two windows 11 opened in the observation surface. By operating each one of the push button switches 12 arranged on the side, an operation start signal of the driver in the display device 1 and an operation stop signal thereof are sent to the control unit,
The number is displayed by operating the push button switch 12,
This is a learning game machine that adds the numbers.
