Abstract:
1. An input device, comprising: a first light guide; a second light guide; a first light source disposed aside the fist light guide, the first light source facing a sidewall of the first light guide for emitting a first light of a first color into the first light guide; a second light source disposed aside the second light-guide, the second light source facing a sidewall of the second light guide for emitting a second light of a second color into the second light guide; a cap being vertically movable disposed on the first light and second light guide, the cap having a first portion and a second portion above the first light guide and the second light guide respectively; and a control module selectively controlling the first light source and the second light source corresponding to a first state and a second state, whereby once the first light source emits the first light, the second light source is turned off, and once the second light source emits the second light, the first light source is turned off; wherein, as the input device is in the first state, the control module controls the first light source to emit the first light in a first direction, and the first light is guided by the first light guide to the first portion in a second direction; and as the input device is in the second state, the control module controls the second light source to emit the second light in the first direction, and the second light is guided by the second light guide to the second portion in the second direction, and wherein the second direction is substantially perpendicular to the first direction.
