Abstract

An input/output or reading/recording device includes an optical reader and a thermal recorder which are both fixedly mounted on a head unit integrally as spaced apart from each other, with the optical reader upstream of the recorder. A feed roller, which is driven to rotate, is pressed against the head unit and it is positioned to be pressed against the optical reader during a reading mode and against the recorder during a recording mode. Depending on the current mode of operation, an original document to be read or a recording medium to be recorded is passed between the head unit and the feed roller. Since the optical reader is located upstream of the recorder, when the device is operating in the recording mode, the optical reader can be activated at least partly to monitor the recording medium during the recording mode of operation.
