性並びに透視性の双方を備えたすべりシートに関
するものである。[Detailed Description of the Invention] The present invention relates to a sliding sheet having both antistatic properties and transparency for use in video cassettes and the like.
ビデオカセツトにおいては、カセツトケース内
面と磁気テープ及びテープリールとの間にすべり
シートを介在させ、すべりシートの低摩擦により
テープの走行摩擦抵抗を軽減することが必要であ
る。 In a video cassette, it is necessary to interpose a sliding sheet between the inner surface of the cassette case and the magnetic tape and tape reel to reduce the running frictional resistance of the tape due to the low friction of the sliding sheet.
かゝるすべりシートにおいては、摩擦静電気の
発生があり、帯電量いかんによつては磁気テープ
に悪影響を与えるおそれがあるので、すべりシー

止性が充分とは云い難い。 Conventionally, transparent sheets made of transparent plastic mixed with transparent conductive powder, such as tin oxide powder, have been known as transparent sliding sheets, but there is a restriction on the conductive powder that can be used due to its transparency. Due to restrictions on conductivity and restrictions on the amount of conductive powder blended to maintain transparency, the surface resistance is high at 1 x 10 8 Ω or more, and it is difficult to say that the conductivity prevention properties are sufficient. .
本考案はかゝる点に鑑み、表面抵抗が著しく低

That is, the sliding sheet according to the present invention is characterized by being formed by laminating and integrating a transparent sheet and a low-friction conductive sheet provided with a large number of small holes to provide transparency.
