Abstract

PURPOSE: To prevent noises due to charging on a magnetic tape surface by stably running the tape by providing the lubricious sheet of a tape cassette with an upright part pressing against the tape.
CONSTITUTION: Lubricious sheet 14 provided between lower case 1 and tape wind layer parts 2 and 3 in a tape cassette is provided with upright parts 15 and 16. Contact parts 17 and 18 of upright parts 15 and 16 are pushed against the magnetic surface side of tape 4 between guide pins 5 and 6 and guide rollers 7 and 8. Since tape 4 zigzags by contact parts 17 and 18 in this constitution, tape 4 running between guide rollers 7 and 8 is applied with tension to stabilize the run of the tape. With respect to charging on the magnetic tape surface, the charge is conducted to the earth from conductive positioning pins inserted into positioning holes 11 and 12 via contact parts 7 and 8, lubricious sheet 14 and projection pieces 19 and 20 by making lubricious sheet 14 conductive, so that spark noises due to the charging on the magnetic tape surface can be prevented.
