Claims

[Scope of utility model registration request]

a cassette housing in which a stored tape is passed along a front opening; a front lid rotatably attached to the cassette housing to cover the front side of the passed tape; and a front lid rotatably attached to the cassette housing to cover the front side of the passed tape; A rear lid rotatably attached to the front lid to cover the rear side, a guided pin provided on the rear lid, and a guide groove provided on the cassette housing to guide the guided pin. and the rear cover is rotated relative to the front cover so as to be spaced apart from the front cover by guiding the guided pin in the guide groove when the front cover is rotated in the opening direction. In a tape cassette configured such that the lid is then rotated in the opening direction together with the front lid, when the tip end surface of the guided pin slides against the bottom surface of the groove extending in the vertical direction of the guide groove. A tape cassette characterized in that an arc-shaped surface portion is provided on one of the tip surfaces and the groove bottom surface in order to reduce the sliding friction between the tip surfaces and the groove bottom surface.
