Cassette loading/unloading apparatus for cassette tape recorder

摘要

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 biases a slider which slides together with a cassette inside a cassette holder at cassette insertion. The ejecting spring is stretched between the cassette holder and an operating plate slidably attached to the cassette holder, functioning as a return spring for the operating plate. The ejecting spring is charged with a biasing force in concert with and only by the slide of the slider at the cassette insertion, and is disengaged from the slider to be locked to a charged state when the slider passes the neutral point of the toggle spring. The charged biasing force of the ejecting spring is caused to act as an ejecting force on the slider at cassette ejection.
