Abstract: A cable stopper structure and an image forming apparatus includes a cable disposed throughout a first passage and a second passage, the second passage having a ceiling height higher than a ceiling height of the first passage, a first component disposed in the first passage and connected to one end portion of the cable, and a second component disposed near an exit of the first passage and connected to the other end portion of the cable, the second component being removable in a direction away from the first component. The cable includes a folded-back portion folded back in the second passage and a rigid portion disposed between the folded-back portion and the first component.

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.

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.

Abstract: An adjust pin (1) for connecting a plurality of blocks (2) to each other to make up a wrist watch band (3) is formed of a metal with a property having a superelastic region where a stress remains constant against variation in strain. The adjust pin (1) is provided with a bent part (5) for causing a bending stress in the superelastic region to act on the inner wall face of a connecting through-hole (2a) of a block (2) in a state wherein the block (2) is joined with an adjoining block (2). When the adjust pin (1) is inserted in the blocks (2), and the bent part (5) is positioned in the connecting through-hole (2a), the bent part (5) provides a force acting on the inner wall of the connecting through-hole (2a) by the agency of the bending stress in the superelastic region, thereby securely holding the adjust pin (1) by a spring force thereof.
