Tape cassette with erasure preventing plug having a head portion with a slanted bottom surface |
摘要 |
A tape cassette includes an erasure preventing plug comprising a circular head portion, a first leg portion, a second leg portion having a diameter less than the first leg portion, and a locking projection. A lower surface of the circular head portion where it joins the first leg portion is angled. The outer diameter of the first leg portion where it connects with the lower angled surface of the circular head portion is determined so as to be generally equal to an inner diameter of a coil spring used for biasing the erasure preventing plug when the erasure preventing plug and the coil spring are mounted in a cassette casing when the coil spring is compressed so as to be in contact with the angled lower surface of the circular head portion.
