The invention relates to an automatic ejecting device for capsules in a coffee machine comprising a housing, a first frame, a second frame and a driving system; two jaws movably jointing with two sides of said second frame respectively, the front portion of each jaw bending and extending to the front surface of said second frame to form a limiting part, these two limiting parts being set apart so as to limit the capsule, and the front portion of each jaw being able to splay and close relating to said second frame; while a first shaft being mounted on the front of each jaw vertically, and a second shaft being mounted on the rear of each jaw vertically, two pairs of guiding grooves being mounted on the housing, the ends of said first and second shafts on the jaws being slide-able in the guiding grooves respectively, each pair of guiding grooves comprising upper guiding groove and lower guiding groove, for guiding the first shaft, therefore, the front portion of each jaw to complete at least one splaying and one closing during said second frame is moving backward. Under the driving system which makes the second word to move and the effect of the collaboration of the first shaft and the guiding grooves, the limiting parts on the front of the jaws can splay on proper time, then the capsule will drop down from the limiting parts.
