Claims

[Claims for Utility Model Registration] A cylindrical member 15 made of an elastic material, and a support member 1 that supports both ends of the cylindrical member 15.
6, a plurality of wings 17 having tip portions 17a in sliding contact with each other at predetermined pitches along the entire circumference of the inner surface of the cylindrical member 15; penetrating the support member 16 with the end portion exposed; a rotating shaft 18 that passes through the center of the cylindrical member 15 and loosely inserts into the elongated hole 22 of the intermediate portion 17b of the wing 17; The rear end portion 17c of the wing 17 is fixed to the rotating shaft 18 in a direction perpendicular to the rotary shaft 18.
A platen roller comprising: a rotating plate 20 which is slidably engaged with a spiral groove 19; and a stopping means 21 which stops the rotation of the rotating shaft 18 at an arbitrary position.
