  • Patent number: 11820617
    Abstract: A printer includes a reverse bending member that bends a paper toward an opposite side to a curl of the paper, and a bifurcated member to correct the curl of the paper with the reverse bending member. The reverse bending member is disposed between a paper drawing position and a paper feeding roller. The bifurcated member is swingably arranged about a shaft extending in a width direction of the paper. The bifurcated member includes an upstream arm and a downstream arm. The upstream arm has a tip positioned between the rolled paper and the reverse bending member, and moves toward or from the reverse bending member. The downstream arm has a tip positioned between the reverse bending member and the feeding roller to be in contact with the paper, and rotates in accordance with a tension level of the paper to press the upstream arm toward the reverse bending member.

  • Patent number: 11815840
    Abstract: A printer includes a case including an input port for rolled paper, a cover provided to be rotatable between a closed position of the input port and an open position of the input port, a holding portion that holds the rolled paper, a biasing member that biases the holding portion in a first direction, a stopper mechanism that stops rotation of the holding portion in the first direction, and a linkage mechanism that rotates the holding portion in conjunction with the rotation of the cover. When the cover is in the closed position, the holding portion rotates in the first direction in accordance with an outer diameter of the rolled paper by a biasing force of the biasing member. When the cover rotates from the closed position to the open position, the holding portion rotates together with the cover against the biasing force of the biasing member.
