Claims

[Claims for Utility Model Registration] A pair of supporting means, each supporting means having an end plate and one end protruding from one surface of the end plate by passing through the end plate in the thickness direction thereof, at least three support rods inserted through the central hole of the end plate, and a gear train including gears provided on the other surface side of the end plate, the other end of the support rod being fixed at a position offset from the center. , the diameter of a common circumscribed circle of the support rod is changed with the same virtual center as the gears rotate in conjunction with each other; a spring that biases the diameter of the circle in a direction that expands or contracts; a rotation shaft fixed to the other surface side of the end plate and having a rotation axis passing through the virtual center; and an end plate of the support rod of each support means. a bearing member that rotatably supports the rotating shaft of each support means with the one end protruding from the support means facing each other; What is claimed is: 1. A support device for roll paper, comprising a holding means for holding the paper in a position such that the paper roll is held at a position such that the paper roll is held at a position such that the paper roll is held at a position such that the paper roll is held at a position where the paper roll is held, and a holding means for releasing the holding state.
