Claims (1)

[Scope of utility model registration request] An opening is provided in the front surface of the cassette case, flanges are provided in the upper and lower corners of the front surface of the cassette case, and substantially triangular bearing holes are provided in the left and right side walls of the cassette case. An opening/closing lid having an arm portion provided with a rotating shaft that is loosely inserted into a substantially triangular bearing hole is attached to the cassette case so that the opening can be opened and closed, and the rotating shaft is mounted on the substantially triangular bearing hole. The opening/closing lid is configured to move within the hole so that the opening/closing lid cannot rotate relative to the cassette casing while the opening/closing lid is engaged with the flange of the cassette cassette. In a cassette hold section into which a tape cassette is loaded, the opening/closing lid is configured to be rotatable with respect to the cassette housing in a state where the opening/closing lid and the flange of the cassette housing are not engaged with each other. The arm portion of the tape cassette loaded with the flange portion of the cassette cassette being engaged with the cassette cassette is connected to the edge of the cassette cassette near a straight line parallel to the vertical direction of the cassette cassette through the rotation axis axis. Correspondingly, a pressing member is provided, and the lid suppressing member biases the opening/closing lid with respect to the cassette case so that the opening/closing lid can rotate with respect to the cassette housing, and this biasing A lid opening/closing member is provided corresponding to the moved opening/closing lid, and the lid opening/closing member is configured to rotate the shifted opening/closing lid with respect to the cassette case.
