Claims

[Scope of utility model registration request]

In an image recording device that uses a feeding roller such as a platen roller to feed recording paper pulled out of a recording paper roll in one direction and records an image on the surface of the recording paper, both ends of a recording paper storage case in which the recording paper roll is stored. A mounting slot capable of supporting both ends of the center pipe penetrated by the bobbin of the recording paper roll is formed in the wall, and a cut surface is formed on the circumferential surface of both ends of the center pipe to prevent rotation of the center pipe relative to the recording paper storage case. An elastic friction resistance member that prevents movement and has a contact protrusion that is pressed against the inner circumferential surface of the bobbin is disposed inside the center pipe, and an opening through which the contact protrusion projects is formed as a part of the peripheral wall of the center pipe. A structure for imparting back tension to roll paper, characterized in that it is formed into a structure.
