Abstract An improved photographic printer of the type wherein photosensitive photographic material is automatically advanced through an exposure area and is marked intermediate adjacent exposures to facilitate the separation or cutting of the different exposures. The improvement consists of a marking system having elements movable in and out of the exposure area to mark the photographic material while it is in the exposure area but without obstructing the photographic material while it is being exposed. In a preferred embodiment, the marking system includes a punch carried by a rotatable eccentric member, the punch being carried in and out of the exposure area on rotation of the eccentric member. The eccentric member is biased to maintain the punch out of the exposure area and is provided with a camming surface engagable by a reciprocal member, cooperation between the reciprocal member and camming surface causing rotation of the eccentric member. The punch may be positioned, and the reciprocating member configured, such that the reciprocating member will activate the punch when the punch is in the exposure area.
In a photographic printer of the type wherein photosensitive photographic material is automatically advanced through an exposure area and having means for marking said photographic material intermediate adjacent exposure locations, the improvement wherein said marking means comprises means rotatable between a first position wherein said marking means is out of said exposure area and a second position wherein said marking means is in marking relation with photographic material within said exposure area.
