A vending machine having a number of separate compartments, each blocked by a rotatable member has a control mechanism, which includes a member insertable in an opening. The proper member will release the blocking members and further includes a portion, where pin stamps operable by the rotation of the blocking members will put a mark. The control portion is formed like a body having transverse bores, each housing an axially displaceable stud, which is operable by a specific pin stamp, and is retainable in either of two axial positions.
