プカセツト。 A detection hole for detecting cassette information is provided on the bottom of the cassette housing, and a plug that is movable up and down and rotatable around the vertical axis is located at a position offset to one side of the detection hole. established in
A spring is provided to press and bias the plug to the lower position, and the plug is provided with a protrusion protruding from its outer peripheral surface to one side, and when the plug is in the lower position, the protrusion is directed toward the detection hole. The detection hole is configured to protrude and close the detection hole with the protrusion,
By moving the plug upward against the spring and rotating it by a predetermined angle around the vertical axis, the protrusion is biased to a position away from the detection hole, thereby opening the detection hole. The tape cassette is characterized in that the plug is positioned at an upper position by pressing and locking the protrusion against the positioning portion by the spring.
