Abstract
A cassette loading/unloading apparatus for a slot-in type cassette tape recorder is provided with a toggle spring and an ejecting spring. The toggle spring is so disposed that a drawing-in stroke is larger than a pushing-in stroke at cassette insertion. The ejecting spring is disposed independently of the sliding stroke of a slider which slides together with a cassette inside a cassette holder at the cassette insertion. A biasing force is charged in the ejecting spring in concert with the ejecting stroke of an ejecting plate at cassette ejection, thereby applying an ejecting force to the slider.
