ABSTRACT:
A printer having a function of reading a bar code attached on a printing paper. A carrier cover of a sensor carrier unit is disposed against the bar-coded surface of the printing paper as located in the printing position by a positioning means, and the printing paper is supported on its rear surface by a guide member, whereupon the sensor carrier unit is moved in the direction of reading the bar code. Therefore, the distance between the bar code and the sensor is normally kept constant so that the printing paper is effectively prevented from being displaced during reading.
