Abstract

An electronic cash register adapted to process business sales information and in addition inventory acquisition information is provided. The cash register includes a keyboard for producing business sales information signals and an additional keyboard for producing inventory acquisition information signals. The business sales keyboard and inventory acquisition keyboard are coupled through a switching circuit to cash register processing circuitry adapted to count, print, display and transmit the information applied to the processing circuit. The switching circuit is adapted to select one of the business sales information or inventory acquisition information to be processed by the processing circuitry.

Claims

1. An electronic cash register including processing circuitry for counting, printing and displaying information applied thereto, the improvement comprising business sales keyboard means for producing signals representative of business sales information, inventory keyboard means for selectively producing signals representative of inventory acquisition information, and switching means coupled to said business sales keyboard means and said inventory acquisition means for selectively applying signals produced by one of said keyboard means to said cash register processing circuit.

2. An electronic cash register as claimed in claim 1, wherein said business sales keyboard means and inventory acquisition keyboard means respectively include pre-pRocessing circuits adapted to pre-process the information produced thereby, said respective pre-processing circuits being coupled to said switching means.

3. An electronic cash register as claimed in claim 2, wherein said business sales keyboard means and inventory acquisition means having a common keyboard and two position switch, said two position switch coupling one of said inventory keyboard pre-processing circuits and inventory acquisition pre-processing circuits to said keyboard.

4. An electric cash register as claimed in claim 3, wherein said switching means respectively coupling said pre-processing circuits to said cash register processing circuit includes a two position switch coupled to said first mentioned two position switch to couple said respective pre-processing circuits to said processing circuitry coincident with the coupling of said single keyboard to said respective pre-processing circuits.
