The present invention relates to an improved automation disk feeding device, comprising: a base, a pushing member, two disk feeding members, and a cover, wherein the base has a operation space, a supporting member and a disk exporting hole. In the present invention, a driving device is used to drive the pushing member to slide forward and backward on the operation space, such that a disk stored in a disk storing district of the cover is able to be exported via the disk exporting hole; Moreover, the disk feeding members are not formed integrally with the base but capable of being assembling to and disassembling from the base, so that, the applications of the improved automation disk feeding device can be increased by way of changing the disk feeding members with different shaped slide ways.
