Electronic calculator with optical input means
First Claim
1. A keyless portable electronic calculating apparatus for entering data and at least one command encoded on a record medium and for performing calculations upon the entered data and displaying calculation results, the apparatus comprising:
- manually manipulatable keyless input means for entering the data and command in response to manipulation of the input means over the data and command on the record medium, said input means being the sole means for entering data and commands;
processor means coupled to the input means for executing each entered command and performing a calculation operation upon the entered data in response to entry of said command by the input means, the entered command specifying the operation to be performed; and
display means coupled to the processor means for displaying results of the operation by the processor means in response to entry of said command by the input means.

Abstract
A keyless electronic calculator includes an optical bar-code reader for entering bar-coded program information, in the form of data and individual commands or complete programs, into the calculator. The calculator also includes a read-write memory unit (RWM) for storing the entered information, a central processing unit (CPU) having a read-only-memory unit (ROM) with pre-stored routines for processing data by executing the entered commands or program under control of the ROM routines, and a display unit for displaying entered data and execution results. An alternative embodiment of the calculator includes both an optical input means and a keyboard.
