ABSTRACT:
An ejector mechanism for unloading the cassette from a cassette-type magnetic tape recorder is provided. The mechanism includes a slide actuator which is mounted in an opening in the housing of the unit for reciprocal rectilinear movement in the plane of the housing, with both the housing and the actuator preferably being composed of a suitable plastic material. The slide actuator includes an integral portion which depends through the opening from the under side of the actuator in position to engage and move a spring-loaded slider on the chassis of the unit from a first to a second position against the bias of its spring. As the slider is moved from its first to its second position, a spring-biased ejector lever under the cassette is released and moves angularly upwardly from a lower position to an upper position to eject the cassette. As the ejector lever moves angularly to its upper position, it latches the slider in its second position. When the cassette is again inserted into the unit, it presses the ejector lever back down to its lower position, which unlatches the slider and causes it to move back to its first position, at which position the slider holds the ejector lever down in its lower position, until the slide actuator is again operated.
