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.
Claims5
A random automatic selector comprising a plurality of code bars which are aligned in parallel and selectively descend corresponding to a designated code number;
- a plurality of file cases each having projections at the bottom corresponding to its own predetermined code number and further having a vertical separation recess at the rear edge and a horizontal separation recess also at the bottom edge;
- an elongated spiral rotor for sequentially lifting and dropping the file cases to drop a designated file cases away from the other file cases;
- means for engaging the vertical recess for separating the designated file case at the rear edge;
- means for holding a front edge of the designated file case;
- and means for engaging the horizontal recess for horizontally pushing out only the designated file case.
