ABSTRACT:
A random automatic selector comprises a spiral rotor for sequentially lifting up and dropping the front edges of file cases so as to weaken the friction between adjacent file cases. A designated file case is dropped to a lower level because projections of the file case are not supported by any code bars since the corresponding code bars are lowered. A separation angle bar is inserted in a vertical separation recess of the designated file case and under the bottoms of the other file cases, the front edges of all of the file cases are lifted up to the normal level at a front edge supporter and the designated file case is pushed out.
