## Abstract

An illumination-type push button device, including a light source portion and an optical member in which one or more lens portions each made of an outgoing surface on a front side and an incident surface on a back side are formed, the optical member configured to receive, from the incident surfaces, light emitted from the light source portion, and to emit the incident light to an outside of the device from the outgoing surfaces, wherein in the outgoing surface of one of the lens portions of the optical member, a single convex portion is formed, the single convex portion being convex in a light exit direction, and in the incident surface of one of the lens portions of the optical member, a plurality of convex portions are formed, the plurality of convex portions being convex reverse to the light incident direction, and smaller than the convex portion of the outgoing surface.

## Claims

### Claim 1

An illumination-type push button device configured to be attached to a game machine, comprising:
a light source portion; and
an optical member in which one or more lens portions each made of an outgoing surface on a front side and an incident surface on a back side are formed, the optical member configured to receive, from the incident surfaces, light emitted from the light source portion, and to emit the incident light to an outside of the device from the outgoing surfaces,
wherein in the outgoing surface of one of the lens portions of the optical member, a single convex portion is formed, the single convex portion being convex in a light exit direction, and
in the incident surface of one of the lens portions of the optical member, a plurality of convex portions are formed, the plurality of convex portions being convex reverse to a light incident direction, and smaller than the convex portion of the outgoing surface.

### Claim 2 (depends on 1)

The illumination-type push button device according to claim 1, wherein both the convex portion of the outgoing surface and the convex portions of the incident surface are spherical.

### Claim 3 (depends on 1)

The illumination-type push button device according to claim 1, comprising a light guide member configured to receive and guide the light emitted from the light source portion,
wherein the light guide member is formed with an upright portion extending to the incident surface of the lens portion,
the upright portion comprises an end surface that is opposed to the incident surface of the lens portion and emits the light to the incident surface, and
the end surface of the upright portion is narrower than the incident surface opposed to the end surface.

### Claim 4 (depends on 2)

The illumination-type push button device according to claim 2, comprising a light guide member configured to receive and guide the light emitted from the light source portion,
wherein the light guide member is formed with an upright portion extending to the incident surface of the lens portion,
the upright portion comprises an end surface that is opposed to the incident surface of the lens portion and emits the light to the incident surface, and
the end surface of the upright portion is narrower than the incident surface opposed to the end surface.
