Abstract
Abstract A compact folding camera including a plurality of housing sections coupled to each other for movement between folded and extended positions and a collapsible viewing device mounted on one of the housing sections for movement between inoperative and operative positions. An elongated link structure is pivotally coupled intermediate its ends to one of the housing sections and has its opposite ends pivotally and slidably coupled to the viewing device. One end of the link structure is mounted in position to be engaged and rotated by a second housing section, during movement of the housing sections into the folded position, to move the viewing device into its inoperative position. When the camera and the viewing device are in their folded positions, inadvertent movement of the viewing device into its extended operative position is precluded by the engagement between the end of the link structure and the second housing section. Movement of the housing sections of the camera toward the extended position is effective to move the second housing section in a direction away from the end of the link structure, thereby allowing rotation of the link structure to move the viewing device toward the extended operative position.
