Optical navigator and transmission interface with rapid read mechanism thereof

The invention discloses an optical navigator and a transmission interface with a rapid read mechanism of the optical navigator. The transmission interface is used for a main control terminal and a controlled terminal. The transmission interface comprises a triggering channel and a data transmission channel. The triggering channel is located in front of the data transmission channel and is capable of enabling the main control terminal to transmit a triggering signal to the controlled terminal. After the controlled terminal receives the triggering signal, the data transmission channel is capable of enabling the controlled terminal to transmit readable data to the main control terminal. The main control terminal and the controlled terminal are suitable for a preset data transfer protocol to directly transmit the readable data, and therefore address data which are relevant to the readable data do not need to be transmitted.
