1. A conveyance apparatus comprising:
a loading portion configured to load a roll sheet wound around a spool shaft; a feeding unit configured to feed the roll sheet loaded on the loading portion; a conveyance roller configured to convey a sheet fed from the feeding unit, wherein the conveyance roller being driven in a first direction conveys the sheet downstream; a control unit configured to perform a first driving operation to drive the feeding unit in a forward direction for feeding the sheet in a direction toward the conveyance roller when the conveyance roller is driven in the first direction, and to perform a second driving operation to drive the feeding unit in a backward direction opposite to the forward direction when the conveyance roller is stopped; a first detection unit configured to detect a rotation amount of the conveyance roller when the first driving operation and the second driving operation are performed; a second detection unit configured to detect a conveyance distance of the sheet drawn out from the roll sheet loaded on the loading portion when the first driving operation and the second driving operation are performed; and a determination unit configured to determine whether an end portion of the roll sheet is fixed to the spool shaft, based on detection result by the first detection unit and the second detection unit.
