Abstract

A button deck includes a substrate and a two-part non-penetrating pushbutton assembly with an upper portion positioned on an upper surface of the substrate and a lower portion positioned on a lower surface of the substrate. The upper portion includes a button face positioned in a button frame that is coupled to the upper surface of the substrate. The button face is configured to be pressed to move within the button frame toward the upper surface of the substrate. The upper portion and the lower portion are configured to work together to provide a signal to an EGM that the button face has been pressed. The pushbutton assembly is non-penetrating because it does not provide any penetration points through the substrate of the button deck.

First claim

What is claimed is:

1. A button deck for an electronic gaming machine (EGM), comprising:
a substrate;
a non-penetrating pushbutton assembly, including:
an upper portion positioned on an upper surface of the substrate, the upper portion including:
a button frame coupled to the upper surface of the substrate;
a button face positioned in the button frame and configured to be pressed such that the button face moves within the button frame toward the upper surface of the substrate from an unpressed position to a pressed position;
a pivotable reflective surface positioned between the button face and the substrate, wherein the pivotable reflective surface is configured to pivot based on movement of the button face; and
a biasing mechanism configured to bias the button face away from the upper surface of the substrate; and
a lower portion positioned at a lower surface of the substrate, the lower portion including:
a light source configured to direct a light beam toward the pivotable reflective surface; and
a light sensor configured to detect the light beam reflected from the pivotable reflective surface;
wherein the non-penetrating pushbutton assembly is configured such that a position of the button face determines whether the light sensor detects the light beam reflected from the pivotable reflective surface; and
wherein the light sensor is configured to signal the EGM when the button face has been pressed.

2. The button deck of claim 1 , wherein the non-penetrating pushbutton assembly is configured such that:
when the button face is in the unpressed position, the light sensor detects the light beam reflected from the pivotable reflective surface; and
when the button face is pressed into the pressed position the pivotable reflective surface pivots such that the light sensor does not detect the light beam reflected from the pivotable reflective surface.

3. The button deck of claim 1 , wherein the non-penetrating pushbutton assembly is configured such that:
when the button face is in the unpressed position, the light sensor does not detect the light beam reflected from the pivotable reflective surface; and
when the button face is pressed into the pressed position the pivotable reflective surface pivots such that the light sensor detects the light beam reflected from the pivotable reflective surface.

4. The button deck of claim 1 , further comprising:
a light sensor array comprising the light sensor, wherein the light sensor array is configured to track movement of the light beam as the button face moves.

5. The button deck of claim 1 , wherein:
the pivotable reflective surface is mounted on an axle coupled to a pinion gear;
a rack is coupled to the button face such that as the button face is pressed the rack moves toward the upper surface of the substrate; and
the rack is configured to engage the pinion gear, such that as the rack moves the pinion gear rotates causing the pivotable reflective surface to pivot.

6. The button deck of claim 1 , wherein the non-penetrating pushbutton assembly is configured such that the light beam from the light source lights up the button face in one or more positions of the button face.

7. The button deck of claim 1 , wherein the substrate comprises a display.

8. The button deck of claim 1 , wherein the pivotable reflective surface is configured to pivot using one or more hinges, flexures, or gimbals.

9. The button deck of claim 1 , wherein the lower portion includes a divider or wall to prevent the light sensor from sensing light other than the light beam reflected from the pivotable reflective surface.

10. The button deck of claim 1 , wherein the lower portion includes a lower control board that is coupled to one or more cables.

11. The button deck of claim 10 , wherein the one or more cables comprise at least one of power cables or communication cables.

12. The button deck of claim 10 , wherein the lower portion communicates with the EGM through the one or more cables.

13. An electronic gaming machine (EGM), comprising:
a game controller; and
a button deck, communicably coupled to the game controller, comprising:
a substrate;
a non-penetrating pushbutton assembly, including:
an upper portion positioned on an upper surface of the substrate, the upper portion including:
a button frame coupled to the upper surface of the substrate;
a button face positioned in the button frame and configured to be pressed such that the button face moves within the button frame toward the upper surface of the substrate from an unpressed position to a pressed position;
a pivotable reflective surface positioned between the button face and the substrate, wherein the pivotable reflective surface is configured to pivot based on movement of the button face; and
a biasing mechanism configured to bias the button face away from the upper surface of the substrate; and
a lower portion positioned at a lower surface of the substrate, the lower portion including:
a light source configured to direct a light beam toward the pivotable reflective surface; and
a light sensor configured to detect the light beam reflected from the pivotable reflective surface;
wherein the non-penetrating pushbutton assembly is configured such that a position of the button face determines whether the light sensor detects the light beam reflected from the pivotable reflective surface; and
wherein the light sensor is configured to signal the game controller when the button face has been pressed.

14. The EGM of claim 13 , wherein the upper portion communicates wirelessly with the lower portion.

15. The EGM of claim 13 , wherein the upper portion communicates wirelessly with the lower portion by interacting with the light beam from the light source.

16. The EGM of claim 13 , wherein the light source is operable to be diverted to light up at least one of the button face or the button frame.

17. A button deck for an electronic gaming machine (EGM), comprising:
a substrate;
a non-penetrating pushbutton assembly, including:
a first portion positioned on a first surface of the substrate, the first portion including:
a button frame coupled to the first surface of the substrate;
a button face positioned in the button frame and configured to be pressed such that the button face moves within the button frame toward the first surface of the substrate from an unpressed position to a pressed position;
a pivotable reflective surface positioned between the button face and the substrate, wherein the pivotable reflective surface is configured to pivot based on movement of the button face; and
a biasing mechanism configured to bias the button face away from the first surface of the substrate; and
a second portion positioned at a second surface of the substrate, the second portion including:
a light source configured to direct a light beam toward the pivotable_reflective surface; and
a light sensor configured to detect the light beam reflected from the pivotable reflective surface;
wherein the non-penetrating pushbutton assembly is configured such that the position of the button face determines whether the light sensor detects the light beam reflected from the pivotable reflective surface; and
wherein the light sensor is configured to signal the EGM when the button face has been pressed.

18. The button deck of claim 17 , wherein:
the light sensor is part of a light sensor array; and
the light beam sweeps along the light sensor array as the button face moves within the button frame.

19. The button deck of claim 17 , w
