A game system and related method comprise releasing playing tokens of visually distinguishable sets associated with different players in turn into a game board forming a generally vertically extending playing zone, so that the playing tokens move downwardly through an array of bumpers in the playing zone, which are arranged to deflect the playing tokens to randomize movement thereof, and collect in a token collection zone below the array of bumpers, which comprises a plurality of side-by-side chutes configured to receive the playing tokens, until a prescribed plural number of the playing tokens of a common one of the sets are located in a line in the token collection zone to define an initial winning set.

A temperature stimulation unit according to one or more embodiments may include a cover, a case with an opening through which the cover is exposed, a temperature changer located on a back surface of the cover, and a coil spring that urges the cover and the temperature changer in a direction to cause the cover and the temperature changer to protrude outside the case through the opening.

A temperature stimulation unit according to one or more embodiments may include a cover, a case including a top portion with an opening, and a control board. The case may include a bottom portion and a side portion having a through-hole. The bottom portion and the side portion may define a clearance at least with the control board.

A presentation control device includes: a first display unit which is a transmissive display unit; a transparent backlight formed of transparent material, provided relative to the first display unit opposite the viewing surface of the first display unit, and configured to emit light toward the first display unit; a light source configured to output object light to the transparent backlight where light from an object provided opposite the light emission plane of the transparent backlight is output toward the transparent backlight and the first display unit; and a display device including a controller configured to control the first display unit, the transparent backlight, and the light source so that light emitted from the transparent backlight shows an image on the first display unit, and so that the object light can pass through the transparent backlight and the first display unit and be output.

A method for playing a value-variable game of chance includes providing a random number generator including one or more walls forming a grid, the grid including an entrance zone and a finishing zone, and the grid being configured to support a transit of a puck from the entrance zone to the finishing zone; providing the finishing zone as including two or more finishing positions, each of the finishing positions configured to receive the puck, and each of the finishing positions being assigned a different finishing position value; providing the grid as including one or more deflectors; introducing a puck into the grid at the entrance zone and subjecting the puck to a force to drive the puck to the finishing zone, and allowing the puck to be deflected off any of the deflectors that it impacts during the puck's transit.

A DC motor control device includes a communication circuit configured to receive a control command specifying a target rotation amount for a DC motor, a sensor interface configured to receive a detection signal from a rotational angle sensor that outputs the detection signal every time the DC motor rotates by a certain rotational angle, a step counter that outputs a count signal every time the detection signal has been received a certain number of times, a controller that, based on the number of times the count signal received, determines a step count representing the total amount of rotation, and generates a control signal that controls the DC motor in accordance with the step count and the target rotation amount, and a drive signal generation circuit that generates a drive signal that rotates the DC motor in accordance with the control signal.

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 display includes a light guide plate having an incident edge surface and an output surface; a plurality of light sources arranged opposed to the incident edge surface; and a plurality of prisms arranged in a main pattern on a surface, each prism having a reflective surface configured to reflect light from any of the plurality of light sources towards the output surface. A curvature of the reflective surface of a first prism arranged in a first sub-pattern of the main pattern, is different from a curvature of the reflective surface of a second prism arranged in a second sub-pattern of the main pattern.

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 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.
