Abstract
An optical identification device includes a top cover, a circuit board, an optical detection module, an optical deviation component and an anti-reflection component. The circuit board is disposed under the top cover. The optical detection module is disposed on the circuit board, and the optical detection module includes a light emitter and a light receiver. The optical deviation component is disposed on the light emitter of the optical detection module and adapted to change a transmission direction of an optical signal emitted by the light emitter, so that the optical signal is projected onto the top cover in an inclined manner. The anti-reflection component is disposed on a surface of the top cover facing the optical detection module and adapted to increase a penetration rate of the optical signal projected onto the top cover.
