Multiple flashlamp unit with indexing means

A flashlamp unit comprising a number of combustion flashlamps arranged in at least one row, mounted on an elongate base plate and extending in parallel with their longitudinal axes, which lamps can each be fired by a stroke against a lamp part, said flashlamp unit comprising a number of striker springs which are locked in an energized condition, which number corresponds to the number of flashlamps and which springs are designed to give a stroke against the lamp part of one of the flashlamps after unlocking, said unit furthermore comprising at least one elongate body which extends in the longitudinal direction of the base plate, is movable in said direction said body having a number of projections, each projection cooperating with one striker spring to unlock the cooperating striker spring, said body, being movable responsive to an associated member to be introduced into the unit from without, characterized in that the direction of the unlocking movement of the body extends mainly perpendicular to the plane of the base plate, a transport spring being present in the unit and exerting on the body a force acting in the longitudinal direction of the base plate so that after each unlocking movement the body moves in the longitudinal direction of the base plate over such a distance that another projection assumes an initial position suitable for unlocking, wherein the body has a recess which is placed so that as a result of the movement of the body said recess is disposed opposite to the member to be introduced into the unit from without when all the flashlamps of the row have been fired.
