Claims

[Scope of utility model registration request]

A case that is a combination of an upper case and a lower case and has an opening for tape loading on the front.
A slider is provided on the bottom side of the lower case to open and close the opening by sliding in the front and back direction, and the slider is provided on the bottom plate of the lower case in correspondence with open and closed positions. In a magnetic tape cassette integrally provided with an elastic protrusion for a slider lock that fits into a lock hole, the slider is arranged such that the elastic protrusion is located at a position on the back side where it abuts at least the front end side protrusion of the elastic protrusion. A magnetic tape cassette characterized in that it has a slope that pushes up the protrusion.
