ABSTRACT:
This invention relates to a shock inhibiting means for use with an automatic shutter latch mechanism of the type which may be released in response to initial shutter blade movement resulting from energization of the shutter drive means and which may thereafter be moved into position to accommodate relatching of the shutter blades in response to film advancement. The shock inhibiting means operates to positively inhibit the accidental unlatching of the shutter blade mechanism resulting from shutter blade movement which might otherwise be occasioned through extraneous vibrations, sudden shock or jarring, and not through intentional actuation of the shutter drive means.
