Bellows type folding camera
摘要:
The bellows type folding camera includes two pairs of collapsable struts symmetrically hinged inside the bellows between the camera housing and the displaceable objective support; the upper and lower struts are interconnected by transverse straps and only one of the struts is operated by an actuation handle whereby the movement of this one strut is transmitted to the remaining struts by a coupler and crank linkage and by the transverse straps.
