Roll-like medium feeding apparatus and recording apparatus

A roll-like medium feeding apparatus in which a support shaft supporting a roll-like medium with a long medium wound in a roll shape is mounted in a freely attached and detached manner, and which unwinds and feeds the long medium from the roll-like medium by rotating the roll-like medium around the support shaft, comprising:

• a mounting portion to which a first shaft becoming the support shaft is mounted with the movement of a direction perpendicular to the first shaft in a freely attached and detached manner;
• a second gear wheel that can be meshed with a first gear wheel integrally provided so as to be disposed concentrically with the first shaft and can be rotated around a second shaft which is disposed so as to be parallel to the first shaft which is in the state of being mounted to the mounting portion;
• and
• a displacement mechanism which is operated so as to displace the second gear wheel between a meshed position to be meshed with the first gear wheel that is in the state in which the first shaft is mounted to the mounting portion and a separated position separated from the first gear wheel.
