ABSTRACT:
A holder device for holding a recording paper roll includes a pair of holders. A first holder has a first fitting portion with an anti-slip device and a first engagement portion. The anti-slip device has two claw members for forward rotation symmetrically disposed each other with respect to a center of rotation of the recording paper roll, two claw members for backward rotation disposed likewise, and springs biasing each claw member to an engagement position. When the first holder rotates in a forward or backward direction, the claw members for forward rotation or for backward rotation move to the engagement positions, respectively, in order to prevent a slip of the recording paper roll. An edge of each claw member is tapered along an attachment direction of the recording paper for easy attachment.
