To provide a machine-glazed paper holding device capable of accurately positioning a machine-glazed paper holder and capable of coping with machine-glazed paper having the wider width.

In a machine-glazed paper holding device, a protrusion 11 of a machine-glazed paper holder 1 is selectively engaged to a plurality of holes of a stage, and the fixing position of the machine-glazed paper holder 1 can be changed. The protrusion 11 is constituted of a root protrusion part 11a and the tip protrusion part 11b, and the outer size in the machine-glazed paper width direction in the root protrusion part 11a is smaller than the outer size La1 in the machine-glazed paper width direction X on the root protrusion part 11a, and the hole of the stage is a root fitting hole having such a shape as to be fitted to the root protrusion part 11a or a tip fitting hole having such a shape as to be fitted to the tip protrusion part 11b. The protrusion 11 is engaged with the hole selected according to the sheet width of machine-glazed paper M, the roll sheet holder 1 is fixed, and therefore, the machine-glazed paper holder can be precisely positioned, and the machine-glazed paper holder can cope with the machine-glazed paper having the wider width.
