A cursor mechanism with an encoder function having a key member, an encoder input transmission member, a plurality of cursor input pressing members and a universal joint. The key member has an encoder rod extending from a center of a bottom thereof and a plurality of cursor rods extending downward from the bottom of the key member surrounding the encoder rod annularly. The transmission member has one end engaged with an encoder and another end connected to a free end of the encoder rod through the universal joint. The key member may be turned to trigger the encoder through the encoder rod and the transmission shaft for generating a respective encoding input signal. On the other hand, the key member may be eccentrically pressed to trigger the micro switch for generating a respective cursor input signal.
