Abstract:
A recording medium conveyance apparatus includes a feeding unit for accommodating a roll pipe and feeding a recording medium, a conveyance unit for conveying the recording medium fed by the feeding unit, and a determination unit for determining an accommodation state of the recording medium accommodated in the feeding unit. The feeding unit includes a driving unit for rotating the roll pipe and a detection unit for detecting a rotational operation of the roll pipe. The conveyance unit, using at least two rollers, conveys or fixes the recording medium by nipping it with the rollers. The determination unit, based on the rotational operation of the roll pipe detected by the detection unit when the recording medium is fixed by the rollers, determines whether the recording medium is fixed to the roll pipe or not.
