Abstract
A printer provided with a storing space for a paper roll having a core hole in the center includes a paper roll holder having a protrusion adapted to fit into the core hole of the paper roll. The paper roll holder is switchable between a protruded state that the protrusion protrudes into the storing space and a retracted state that the protrusion retracts from the storing space. The printer further includes a stopper adapted to engage with the paper roll holder while the paper roll holder is in the protruded state to prevent the protrusion from turning to a predetermined direction. The paper roll holder moves when pushed by the paper roll that is being set into the storing space. Movement of the paper roll holder releases the engagement with the stopper to allow the protrusion to turn to the predetermined direction.
