Abstract

A self-contained, portable data entry terminal positioned within a cordless, wand-type enclosure. Positioned within the enclosure is a bar code optical sensor/emitter, signal conditioning electronics, a microprocessor, a memory, and a rechargable battery. The bar code optical reader functions as both a sensor and an emitter to permit the readout of data stored in the memory.

Claims

1. A self-contained, portable data entry terminal comprising:

a bar code optical sensor;

signal conditioning means responsive to said optical sensor;

processor means responsive to said signal conditioning means for processing bar code input data sensed by said sensor;

memory means for storing said bar code input data;

a power source; and

a self-contained, cordless, wand-type enclosure for housing said sensor, said signal conditioning means, said processor means, said memory means and said power source.

2. A self-contained, portable data entry terminal according to claim 1, further comprising:

visual output means responsive to said processor means for visually signalling operation of said data entry terminal.

3. A self-contained, portable data entry terminal according to claim 1 or 2, wherein said sensor is a sensor/emitter and further comprising:

means for conducting said input data stored in said memory means to said optical sensor/emitter.

4. A self-contained, portable data entry terminal according to claim 3, wherein said conducting means includes said microprocessor for reading the input data stored in said memory means and conducting said data to said optical sensor/emitter.

5. A self-contained, portable data entry terminal according to claim 3, wherein said input data pulses said optical sensor/emitter to provide an optical output indicative of said stored input data.
