Claims

[Scope of utility model registration request]

A rotating device having a carrier that moves along a platen, a motor mounted on the carrier, and a number of locking portions and a number of through holes arranged in an annular shape around a center of rotation and connected to the motor. a daisy wheel having a body, a plurality of locking parts engaged with the locking parts, a detection hole facing any of the through holes and through which light from a photoelectric detector passes; a back surface of the daisy wheel; a wheel case that covers a part of the outer periphery; a holder that removably holds the wheel case and is rotatably attached to the carrier with an axis parallel to the platen; and a type portion of the daisy wheel. A daisy wheel printer comprising: a printing hammer facing the back surface of the daisy wheel; and an elastic piece integrally formed with the wheel case and elastically contacting the back surface of the daisy wheel.
