Application ID: 05470316

Base Claim:
1. In a data identification and information system having a writer unit with first input and output means and second input and output means, said first input and output means enabling the printing of plain language alpha/numeric data on at least one recording medium within said writer unit in response to signals from said writer unit or external data signals, said second input and output means generating coded output signals in response to said writer unit or external data signals, first record forming means responsive to said coded output signals for duplicating in coded form said plain language alpha/numeric data printed by said writer unit, reader means selectively connected to said first input and output means or said second input and output means to actuate said writer unit to print plain language alpha/numeric data in accordance with coded recorded information stored on a recording medium read by said reader means, said reader means actuating said first record forming means for duplication of coded information on the recording medium within said reader means, second record forming means for recording coded data input signals, the improvement comprising: data storage means for temporarily storing said coded signals representative of specified identification data printed by said writer unit from said second input and output means during a storage operation mode and being unresponsive to said coded signals during a non-storage operation mode; said second record forming means recording said coded signals stored in said data storage means onto said at least one recording medium containing the plain language alpha/numeric data previously printed thereon by said writer unit; and control means for transferring said coded signals from said second input and output means to said storage means and for transferring said coded signals from said storage means to said second record forming means.

Claim 2:
2. Apparatus as in claim 1, wherein said data storage means comprises: a plurality of shift registers for receiving coded identification data from said second input and output means and adapted to recirculate stored identification data simultaneously with the transfer of said data to said second record forming means; a plurality of first converter means for filtering and changing the logic level of said coded identification data from said second input and output means to said shift registers; second converter means for changing the logic level of said data from said shift registers to said second record forming means; and a plurality of gate selector units each being connected between a respective one of said first converter means and a respective one of said shift registers; and wherein said control means controls said gate selector units to transfer data from said second input and output means and for recirculating said stored identification data between said shift registers.
