<p>PURPOSE: To provide a bar code communication interface system and a system for the same with which bar code information outputted from a bar code decoder is asynchronously and exactly transmitted to a host computer while using an asynchronous communication controller. CONSTITUTION: Bar code information data outputted from a decoder dedicated integrated circuit 21 are received by a microcontroller 11, proper bar code information data are outputted and the bar code information data are serially converted by an asynchronous communication controller 12 under the control of microcontroller 11 and transmitted later through an ILC232 inverting line driver 13a and an RS-232C serial communication interface 13b to a host computer.</p> |
