Abstract

A winding apparatus includes a winding core unit onto which a continuous medium is to be wound, the winding core unit having a notched portion having a shape in which a part of the winding core unit in a circumferential direction is cut out as viewed in an extending direction of the winding core unit, and a notch complementing unit to be detacheably inserted into the notched portion from one end portion side in the extending direction of the winding core unit, the notch complementing unit being configured to complement the notched portion.

First claim

What is claimed is:

1. A winding apparatus comprising:
a winding core unit onto which a continuous medium is to be wound, the winding core unit having a notched portion having a shape in which a part of the winding core unit in a circumferential direction is cut out as viewed in an extending direction of the winding core unit; and
a notch complementing unit to be detacheably inserted into the notched portion from one end portion side in the extending direction of the winding core unit, the notch complementing unit being configured to complement the notched portion.

2. The winding apparatus according to claim 1 , wherein when the notch complementing unit is inserted into the notched portion, the notch complementing unit is switched between a contact position in which the notch complementing unit comes into contact with the continuous medium wound around the winding core unit and a separated position in which the notch complementing unit is separated from the continuous medium radially inward toward the winding core unit.

3. The winding apparatus according to claim 2 , further comprising:
a flange forming unit configured to move in the extending direction of the winding core unit,
wherein the flange forming unit includes:
a flange unit configured to move in the extending direction of the winding core unit between a guide position for guiding the continuous medium by guiding the continuous medium to be wound around the winding core unit in a width direction of the continuous medium, and a non-guide position away from the position at which the continuous medium is wound around the winding core unit than the guide position; and
a switching regulating unit configured to move together with the flange unit, and when the flange unit is in the guide position, regulate the notch complementing unit so as not to be switched from the contact position to the separated position and when the flange unit is in the non-guide position, allow the notch complementing unit to be switched from the contact position to the separated position.

4. The winding apparatus according to claim 3 , wherein the winding core unit includes:
a medium insertion unit into which an end portion of the continuous medium is to be inserted;
a medium receiving unit disposed in the medium insertion unit; and
a medium holding unit disposed in the medium insertion unit, the medium holding unit being configured to be switched between a holding position for holding the continuous medium inserted into the medium insertion unit against the medium receiving unit and a non-holding position away from the medium receiving unit more than the holding position, and
the flange unit includes:
a holding operation unit detachably attached to the winding core unit, and when the flange unit is attached to the winding core unit, causes the medium holding unit to be located in the holding position, and when the flange unit is detached from the winding core unit, causes the medium holding unit to be located in the non-holding position.

5. A printing apparatus comprising:
a printing unit configured to perform printing onto a continuous medium;
a winding core unit onto which the continuous medium is to be wound, the winding core unit having a notched portion having a shape in which a part of the winding core unit in a circumferential direction is cut out as viewed in an extending direction of the winding core unit; and
a notch complementing unit to be detacheably inserted into the notched portion from one end portion side in the extending direction of the winding core unit, the notch complementing unit being configured to complement the notched portion.
