1. A paper roll holding structure, comprising: two side plates configured to guide a paper roll formed by winding a paper, each side plate having a guide surface opposing an opposite side surface of the paper roll; holding members configured to hold the paper roll, each holding member having a first end being capable of being inserted into an axial hole of the paper roll and a second end formed at the opposite side of the first end; support members arranged on the guide surfaces of the side plates to block the holding members from moving downwards from a substantially horizontal position when the first end of each holding member is inserted into the axial hole of the paper roll, the support members having pivot shafts configured to rotatably support the second ends of the holding members in such a manner as to allow the holding members to swing upwards, wherein the support member includes a paper roll guide portion having a slant surface configured to make contact with edges of the paper roll when the paper roll is pushed upwards and formed in a lower portion of the support member, wherein the slant surface is configured to gradually extend away from the side plate in a direction perpendicular to the side plate as the paper roll guide portion extends from a vertical lower end of the slant surface toward a vertical upper end of the slant surface, and wherein the holding members are configured to hold the paper roll by making contact along at least two lines when the holding member are inserted into the axial hole of the paper roll.
