Abstract
A recording apparatus for performing recording onto a recording medium includes a transporting device for transporting the receding medium, the transporting device including a combination of driving elements including a transporting motor and a transporting roller and set so that, upon completion of a turn of the transporting roller, the other driving elements are reset to an initial state, a detecting section, arranged on the transporting roller, showing a reference position of the transporting roller, a reference position detector detecting the detecting section and outputting a detection signal, a rotation angle measuring device, being detachably attached to the transporting roller, for measuring a rotation angle of the transporting roller, a storage unit for previously storing a number of driving pulses corrected so that the amount of transportation generated by the transporting roller is kept constant, on the basis of information from the rotation angle measuring device for a turn of the transporting roller, and a controller driving-controlling the transporting motor on the basis of the corrected number of driving pulses store in the storage unit.
