Abstract
Abstract A one-touch device for removably attaching an audio adapter to optical equipment. A receptive mechanism is provided on one of the audio adapter or the optical equipment, and an insertion mechanism is provided on the other. A lock release mechanism and a movable plate associated with the insertion mechanism may be controlled by a common spring, thus reducing the number of necessary parts. Only a single touch is necessary to disengage the mechanisms from each other.
