Fixation roll of copying machine

Abstract

Abstract PURPOSE:To enhance heating efficiency and to reduce temp. rise of an induction coil, by constituting the main body of a cylindrical roll out of stainless steel small in effective resistance ratio. CONSTITUTION:The main body R of a cylindrical roll is made of stainless steel, and the induction coil L is arranged concentrically in the body R, and a bobbin B for winding the coil L is disposed. The effective resistance ratio of stainless is higher than that of Al, iron, and the like metal, therefore, when the body R is made of stainless steel, an amt. of current to be supplied to the coil L necessary to heat the body R to a prescribed temp. can be made smaller, therefore, heating efficiency can be enhanced and the temp. rise of the induction coil L can be reduced.
