PROBLEM TO BE SOLVED: To provide an inexpensive roll sheet mounting device which is commonly used for a plurality of core tubes in different outer diameters. SOLUTION: The roll sheet mounting device includes a cylindrical body 1a formed with plastic having circular openings 4a and 4b at both ends thereof; and a plurality of press pieces 5 respectively extending along a central axis 8 from the vicinity of the openings 4a to the vicinity of the openings 4b on the inner periphery of a side surface 2 of the cylindrical body 1a. The press pieces 5 are disposed to gradually approach the central axis 8 from a base 5b to a front end 5a, and are substantially equally spaced with respect to the peripheral direction of the side surface 2. Side openings 3 are formed correspondingly to the respective press pieces 5 on the side surface 2 of the cylindrical body 1a. COPYRIGHT: (C)2011,JPO&INPIT |
