An object of the present invention is to allow a medicine dispensing cassette to be easily disassembled. The medicine dispensing cassette according to the embodiments of the present invention may include a main member, a first sub-member, a second sub-member and a third sub-member. The main member further includes an engagement release member so that when said engagement release member is moved to a first position (F), the engagement between the main member and the first sub-member is released, making it possible to separate the first sub-member from the main member. In the same manner, when the engagement release member is moved to a second position (S), the engagement between the main member and the second sub-member is released, making it possible to separate the second sub-member from the main member. The third sub-member can be removed from the main member independently from an operation of the engagement release member.
