A technique capable of inhibiting a decrease in work efficiency at the time of replacing a roll sheet is to be provided. The present invention includes: a supply unit configured to support, in a rotatable manner, the roll sheet to which a shaft member is attached and supply a sheet unwound from the roll sheet; a base part arranged above the supply unit and configured to be capable of supporting the roll sheet; and a guide part configured to guide the roll sheet to which the shaft member is attached to the supply unit via the shaft member, wherein the shaft member is inserted into the guide part by moving the roll sheet to which the shaft member is attached from the base part.

A medium supporting device including a support part configured to support a roll body on which a sheet shaped medium is wound, a shaft serving as a rotary axis of the roll body and secured with the support part, and a driver configured to rotate the roll body supported by the support part. The shaft is secured to the support part by using a metal plate having a flat surface provided with an insertion hole, the insertion hole being a hole into which the shaft is inserted. An outer circumference part of the metal plate is restricted from moving in a rotation direction of the roll body relative to an inner circumference part of the support part.

A medium wind-up device is provided to suppress causing a wrinkle at a time of winding a medium, and also suppress a fluctuation of a winding position. The medium wind-up device includes: a tension roller that presses a medium, which is belt-shaped and transferred in a transfer direction that is predetermined, in order to provide the medium with a tension; a reversing roller that reverses the medium pressed by the tension roller, and the reversing roller being rotatable so as to follow a move of the medium; a loading mechanism that is capable of placing a load against a rotation of the reversing roller; and a wind-up portion that winds up the medium reversed by the reversing roller.

A textile feed for a stepped operation digital textile printer, comprises a textile feeding mechanism, and a tension storage mechanism. The textile feeding mechanism feeds the textile in a forward direction onto the printer, but is at the same time mechanically connected to a tension storage mechanism which is tensioned by the forward feeding. At the end of the feed step, the tension storage mechanism releases respectively stored tension to cause the feed mechanism to briefly reverse feed, thereby to pull the textile taut and take up any slack caused by the feeding step. The textile is thus kept taut, to allow effective digital printing by the printer.
