Sheet roll producing apparatus, sheet roll discharging apparatus, and core supplying apparatus

A sheet roll discharging apparatus for discharging a sheet roll formed by winding up a heat transfer recording sheet, obtained by forming a transfer ink layer on one surface of a base, around an outer periphery of a core, comprising:

• a cantilever shaft supporting a plurality of sheet rolls after wound and having a rotation drive portion;
• a tray provided below the cantilever shaft;
• and
• a stopper for pushing a rotation-drive-portion-side end of a sheet roll located on a rotation drive portion side among said plurality of sheet rolls.

A core supplying apparatus for supplying a core to a winding apparatus for forming a sheet roll by winding up a heat transfer recording sheet, obtained by forming a transfer ink layer on one surface of a base, around an outer periphery of a core, comprising:

• a cantilever shaft supporting a plurality of cores and having a rotation drive portion;
• a tray disposed below the cantilever shaft so as to be movable up and down and to move in a direction of an axis of the cantilever shaft as carrying a plurality of cores;
• and
• core stoppers provided at constant intervals corresponding to the cores on the tray and pushing the cores when the cores on the tray are made to be set on said cantilever shaft from the free end of the cantilever shaft.
