Unwinding apparatus for unwinding tape-like sheet member.

摘要

In the present invention, an unwinding shaft (9) in a cassette (30) is rotated to unwind a sheet member (6) by an unwinding mechanism (40 and 50) in connection with a movement of a head attaching member (7) when the head attaching member (7) is such a direction as to separate the head member (4) from the sheet member (6) in the cassette (30). Also, the sheet member (6) is applied with a back tension in a direction opposite to the winding tension by a back tension applying mechanism (42 and 60) when the winding shaft (8) winds the sheet member (6) by a winding device of a winding motor (M). <IMAGE>
