ABSTRACT:
A printing apparatus includes traveling means for traveling in the recording directions by holding it for recording on a recording medium, guiding means for guiding the traveling means, and reading means detachably held by the guiding means. This printing apparatus further includes electrical connectors provided for the reading means and printing apparatus, respectively, for electrically connecting them, which are arranged to be installed or removed simultaneously by the operation of mounting the reading means on or demounting it from the guiding means, and also, detecting means for detecting a state of the reading means being mounted on the printing apparatus, controlling means for holding the power-supply to the traveling means and recovery means for recovering the performance of the recording means in a state of being cut off in accordance with the detection of the detecting means when the reading means is mounted on the printing apparatus. With such structure, it is possible to mount a reading unit in the interior of the printing apparatus easily without removing recording means, and at the same time, to prevent the reading unit from being stained by recovery means for recovering the performance of recording means.
