The connection structure of flexible boards permits efficient positioning
and connecting of a plurality of flexible boards arranged one over the
other in a camera by providing a pair of pin elements in a protruding
condition in a base portion and forming on one of the pin elements a
groove to be engaged with flexible boards. A lens device includes a base
metal sheet of metal and pin elements of plastic provided in a protruding
condition in the base metal sheet. The pin element has a groove formed on
an outer periphery surface of the opposite side to the pin element. A main
flex or a shutter flex has holes formed therein, into which the pin
elements are to be inserted. A spacing between the holes is formed a
little smaller than a spacing between the pin elements.
