Abstract

PURPOSE:To manufacture an elastic piece for preventing the slackness of a tape of a single member with proper spring property and surface roughness inexpensively and so as to be of good quality by forming it by using a tainless steel thin plate. CONSTITUTION:The elastic piece 1 is formed of the stainless steel thin plate, 0.01-0.1mm thick and of surface roughness of <=2.0 S. One side end 1a of the elastic piece 1 in a tape traveling direction is a fixed end, and the other side end 1b is a spring acting end to press against a guide roller. A bending part 1c lying along the axial direction of the guide roll is formed at the side end 1b. At the side end 1a, a turnup 1d for preventing the falling out of the elastic piece 1 after being fixed in a cassette is formed. Besides, at the center of the elastic piece 1, a window hole 1e for ensuring the optical path of an optical sensor to detect a leader tape part at a tape end is formed.
