ABSTRACT:
In the present invention, an unwinding shaft in a cassette is rotated to unwind a sheet member by an unwinding mechanism in connection with a movement of a head attaching member when the head attaching member is such a direction as to separate the head member from the sheet member in the cassette. Also, the sheet member is applied with a back tension in a direction opposite to the winding tension by a back tension applying mechanism when the winding shaft winds the sheet member by a winding device of a winding motor.
