1. A communication system for a wireless bar code reader comprising:
- a wireless bar code reader transmitter for reading bar code information and transmitting a radio signal; and
a receiver for receiving the radio signal from said wireless bar code reader transmitter and transmitting reception data to a host computer;
said wireless bar code reader transmitter including;
an optical section for detecting a bar code and outputting a signal representing the detected bar code;
an interpretation section for interpreting the signal from said optical section and converting into data; and
a radio transmitting section for modulating the data into the radio signal and radiating in air, andsaid receiver including;
a radio receiving section for receiving and demodulating the radio signal radiated in air;
an analyzing section for analyzing and performing error detection and error correction as to the demodulated radio signal to thereby convert the demodulated radio signal into reception data and for transmitting the reception data to said host computer when the analyzing section determines that the demodulated radio signal is normal; and
a reception indication section for indicating to a user that the reception data is received.

Abstract
A communication system for a wireless bar code reader includes a wireless bar code reader transmitter for reading bar code information and transmitting a radio signal, and a receiver for receiving the radio signal from the wireless bar code reader transmitter and transmitting reception data to a host computer, wherein the receiver includes a reception indication section for indicating that the reception data is received. Accordingly, it is possible to notify an operator that the data has been transmitted normally and further to urge the operator to retransmit the data when the data has not been transmitted normally.
