Abstract
A continuous viscoelastic gasket 2 is compressively sandwiched between mating grooves and surfaces of a camera body 1 and a hinged rear cover 3 to tightly seal the film compartment against moisture and dust when the cover is closed. The interlocking pin 10 of the automatic film counter restoring mechanism is protectively disposed within the gasket perimeter and is engaged by a tab 9b extending inwardly from a reinforcing plate 9 mounted on the rear cover.
