Abstract:
1. An illumination-type push button device configured to be attached to a game machine, comprising: a board for light source; a diffusing lens having a dome shape with a convex front surface and a concave back surface, the back surface being opposed to the board for light source; a first light source portion and a second light source portion mounted on a side opposed to the diffusing lens of the board for light source; and a light guide member that is fitted in a through-hole formed in the diffusing lens so as to penetrate from a side of the back surface to a side of the front surface, is mounted on the board for light source so that one end side thereof covers the first light source portion, and is projected from the diffusing lens on another end side in a direction from the back surface to the front surface, wherein the diffusing lens is configured such that light of the second light source portion enters the diffusing lens from the back surface, and is diffused from the front surface of the diffusing lens, thereby being irradiated to an outside of the device, and the light guide member is configured such that light of the first light source portion enters the light guide member from an incident surface opposed to the first light source portion on the one end side of the light guide member to be guided inside the light guide member, and exits from an outgoing surface on the other end side of the light guide member, thereby being irradiated to the outside.
