Abstract
The electronic device includes a device housing, an emitter, a receiver, and a reflection structure. The emitter is separated from the device housing and emits an optical signal. The receiver is disposed on the device housing for receiving the optical signal. The reflection structure is formed on the device housing and neighboring to the receiver. When the emitter is disposed in front of the device housing, the optical signal transmitted from the emitter directly reaches the reflection structure and is reflected by the reflection structure, and then the optical signal travels toward the receiver.
