Title:
SMOOTH SHEET OF CASSETTE CASE
Document Type and Number:
Japanese Patent JPH0547148
Kind Code:
A
Abstract:
PURPOSE:To provide the smooth sheet which is transparent in the entire part of a conductive layer and smooth sheet, allows the observation of the state of a magnetic tape from the outer side of the cassette case and is shielded of static electricity since the conductive fillers incorporated into the conductive layer of the smooth sheet are a TCNQ complex, and which has versatility since there is no need for changing the form of the smooth sheet even if the design of the cassette changes. CONSTITUTION:The smooth sheet 11 of the cassette case 2 in which the transparent smooth sheet 11 formed to prevent the electrification by friction is housed is constituted by forming the transparent conductive layer 13 for which the 7, 7, 8, 8-tetracyanoquinoclimethane complex (TCNQ complex) is used as the conductive fillers 15, and a silicone layer 14 on the winding part side surface of a biaxially stretched polyester film.
