A sheet can be securely drawn out of a sheet roll irrespective of an outer diameter of the sheet roll, and then, can be conveyed. A driven roller moves according to the outer diameter of the sheet roll, so as to be brought into press-contact with an outer periphery of the sheet roll from below, with respect to the direction of gravity, irrespective of the outer diameter of the sheet roll. An arm member moves according to the outer diameter of the sheet roll, so as to guide a lower side of the sheet drawn through above the driven roller irrespective of the outer diameter of the sheet roll.

According to an example, a media loading device may comprise a motor and a leading-edge sensor. The motor may rotate a media roll having a leading-edge in a winding direction and unwinding direction, the motor being controlled by a processor. The leading-edge sensor may comprise a pivot arm and a detecting element. The pivot arm may contact the media roll and the detecting element may issue a leading-edge presence signal to the processor upon contact between the detecting element and the leading-edge occurs.
