A dice shaker device and method for providing a randomized state of at least one die. The dice shaker device includes a dice plate, a dice plate actuator configured to apply a reciprocating force to the dice plate, a casing, a circumferential ridge surface extending around an outer perimeter of the dice plate, and a dice rolling space at least partly defined by the casing, the dice plate, and the circumferential ridge surface. The circumferential ridge surface can be arranged in parallel with an upper surface of the dice plate, and the circumferential ridge surface can have a width that is equal to or less than half a width of the at least one die that the dice shaker device is arranged to provide a randomized state of.

The present invention includes a configuration to move a transport body 500 in conjunction with movement of a moving body 200 due to repulsion applied between respective magnetic materials 213 and 523 when the moving body and the transport body are in a close location relation, and, when the moving body separates from a range of the close location relation due to halfway stop of the transport body, the transport body is moved in the opposite direction to stop at a predetermined end portion stop position, subsequently only the moving body is caused to travel in a direction further away from the transport body, and the moving body is returned into the range of the close location relation by causing the moving body to travel toward the transport body at a speed resistible against the repelling force.

A first light guide plate and a second light guide plate are arranged facing each other. A microprojection group comprising a plurality of microprojections is arranged in the visual recognition region of the surface facing the first light guide plate in the second light guide plate. The plurality of microprojections have a height and arrangement that ensure a distance where interference fringes are not visually recognized between the first light guide plate and the second light guide plate in contact with the second light guide plate. The microprojection group and the dimples configuring a design part formed on the second light guide plate are formed on an identical surface.

A gimmick device according to one or more embodiments may include a gimmick and a voice coil motors (VCM). The VCM includes a casing, a permanent magnet, a yoke and iron-core, a bobbin, and a coil part. The gimmick is mounted to the casing on a movable side. The coil part includes a drive and primary coil serving as a drive coil and a primary coil of a displacement sensor including a differential transformer, the drive and primary coil being interlinked with a magnetic flux by the permanent magnet, and two secondary coils of the displacement sensor. The yoke and iron-core may be disposed in a central space defined in the coil part, and serves as an iron core of the displacement sensor.

A display is disclosed that may include: a light guide plate having an incident surface; and light sources arranged opposed to the incident surface. The light guide plate may include a plurality of prisms arranged in a pattern on a surface on one side and may have a reflective surface configured to reflect light from any of the plurality of light sources incident into the light guide plate from the incident surface, to be emitted from an outgoing surface on another side of the light guide plate. A curvature of the surface on one side of the reflective surface and of a first prism arranged in a first sub-pattern included in the pattern among the plurality of prisms is different from a curvature of the surface on one side and of a second prism arranged in a second sub-pattern.

A display device according to one or more embodiments may include a lightguide plate comprising a transparent part, and an incident surface, the lightguide plate configured to display at least one pattern; and a light source facing the incident surface. The lightguide plate may include a plurality of prisms on a surface of the lightguide plate, the plurality of prisms being arranged along the at least one pattern to reflect light emitted from the light source and entering the lightguide plate through the incident surface out of the lightguide plate through an emission surface of the lightguide plate, and a transparent protective layer covering at least a part of the emission surface, the protective layer having a smaller refractive index than the lightguide plate.

The objective of the present invention is to provide a game machine employing computer simulation. This game machine is provided with a display device in a casing, and includes a game processing unit which executes a game process, and a consumption information processing unit which causes the display device to display consumption information relating to a game.
