Abstract

Operations on documents 10, traveling in transport 11, are controlled by reference to a transport state counter register 12 which is incremented by transport emitter 13. A document 10, bearing information indicating operations to be performed upon it such as printing, microfilming, etc., and sorting into a destination bin 15, 16, etc, passes through reader 17 where the operations and destinations are determined. Each operation or destination bin is a known distance from the reader 17, as measured in terms of emitter counts of the transport 13. These known offset displacements are stored in read/write memory 18.

Operations on documents 10, traveling in transport 11, are controlled by reference to a transport state counter register 12 which is incremented by transport emitter 13. A document 10, bearing information indicating operations to be performed upon it such as printing, microfilming, etc., and sorting into a destination bin 15, 16, etc, passes through reader 17 where the operations and destinations are determined. Each operation or destination bin is a known distance from the reader 17, as measured in terms of emitter counts of the transport 13. These known offset displacements are stored in read/write memory
18. When the operations are determined in response to reading at reader 17, the displacement to the required operation retrieved from memory 18 is combined at adder 19 with the current contents of transport state counter 12 to produce a subsequent transport state at which the selected operation is to occur. This control count is entered into a register 20, 21, etc., associated with the individual document. The contents of all registers 20, 21 are periodically compared with the contents of state counter 12. When this comparison indicates that the transport has reached that state at which an operation on a particular document is to be performed, a suitable control signal is sent, for example, to operate microfilm unit 22, or to select a particular selector bin vein such as selector 23.
