Abstract
A roll paper supplying device and a recording apparatus include an unwinding shaft and a bearing that support a roll having a roll paper wound around a core in a manner that the roll paper can be fed out from the roll, a fixed braking section and a movable braking section that is configured to come into contact with an outer peripheral end face of the roll and brake a rotation of the roll in feeding out of the roll paper, and a radial direction movement section that is configured to move the fixed braking section and the movable braking section in a radial direction of the roll according to a diameter of the roll which decreases as the roll paper is fed out.

A roll paper supplying device comprising:
- a roll support member that supports a roll having a roll paper wound around a core in a manner that the roll paper can be fed out from the roll;
- a rotation braking section that is configured to come into rolling contact with an outer peripheral end portion of the roll and brake a rotation of the roll in feeding out of the roll paper;
- and
- a radial direction movement section that is configured to move the rotation braking section in a radial direction of the roll according to a diameter of the roll which decreases as the roll paper is fed out,
- wherein the rotation braking section comprises;
- a fixed braking section that is provided so as to come into rolling contact with one end in a width direction of the roll and fixed in an axis direction of the roll;
- a movable braking section that is provided so as to come into rolling contact with the other end in the width direction of the roll and movable in the axis direction of the roll;
- and
- a holding biasing section that biases the movable braking section to hold the roll between the fixed braking section and the movable braking section.
A recording apparatus comprising:
- a roll support member that supports a roll having a roll paper wound around a core in a manner that the roll paper can be fed out from the roll;
- a rotation braking section that is configured to come into rolling contact with an outer peripheral end face of the roll and brake a rotation of the roll in feeding out of the roll paper;
- a radial direction movement section that is configured to move the rotation braking section in a radial direction of the roll according to a diameter of the roll which decreases as the roll paper is fed out;
- a recording section that performs a recording operation on the roll paper fed out from the roll;
- and
- a winding unit that winds up the roll paper into a roll shape after the recording operation,
- wherein the rotation braking section comprises:
- a fixed braking section that is provided so as to come into rolling contact with one end face in a width direction of the roll and fixed in an axis direction of the roll;
- a movable braking section that is provided so as to come into rolling contact with the other end face in the width direction of the roll and movable in the axis direction of the roll;
- and
- a holding biasing section that biases the movable braking section to hold the roll between the fixed braking section and the movable braking section.
