Claims

[Claims for Utility Model Registration] (1) In a sprocket conveying sheet having sprocket pin engagement holes arranged correspondingly on both left and right side edges along the longitudinal direction, sprockets on both side edges of the sheet 1. A sprocket conveying sheet, characterized in that pin engaging holes are formed along the longitudinal direction of the sheet to correspond to irregular hole shapes for every predetermined number of holes. (2) A seat having sprocket pin engagement holes arranged correspondingly on both the left and right side edges along the longitudinal direction, and located corresponding to the sprocket pin engagement holes on each side edge of the seat, and said sprocket The sprocket is equipped with a pair of sprockets each having a sprocket pin protruding from the outer periphery that engages with the pin engagement hole, and the sprocket rotates in the longitudinal direction as the sprocket rotates due to cooperation between the sprocket pin engagement hole and the sprocket pin. In a sheet conveyance sprocket device that conveys the sheet along the sheet, protrusion engagement holes are arranged side by side of the sprocket pin engagement hole on at least one side edge of the sheet, A sprocket device for conveying a sheet, characterized in that positioning protrusions are provided on the outer periphery of the sprocket corresponding to the sprocket pin engagement holes of the sheet, the positioning protrusions sequentially engaging with the respective protrusion engagement holes as the sheet is conveyed.
