Abstract

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.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 72 words
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.
Claim 2
Dependent Claim 72 words
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.
Claim 3
Dependent Claim 13 words
The photographic printer of claim 1 wherein said rotatable means comprises punch means.
Claim 4
Dependent Claim 38 words
The photographic printer of claim 1 wherein said rotatable means comprises camming surface means, said marking means further comprising means selectively engaging said camming surface means for rotating said rotatable means from said first to said second position.
Claim 5
Dependent Claim 15 words
The photographic printer of claim 3 wherein said selectively engaging means comprises selectively reciprocal means.
Claim 6
Dependent Claim 54 words
The photographic printer of claim 4 wherein said reciprocal means continues its travel following rotation of said rotatable means to said second position, said punch means being within the path of said reciprocal means when said rotatable means is in said second position and being actuated by the continued travel of said reciprocal means.
Claim 7
Dependent Claim 16 words
The photographic printer of claim 5 wherein said rotatable means is biased in said first position.
Claim 8
Dependent Claim 17 words
The photographic printer of claim 6 further comprising means for directing waste away from said exposure area.
Claim 9
Dependent Claim 13 words
The photographic printer of claim 7 wherein said reciprocal means comprises pneumatic means.
Claim 10
Dependent Claim 13 words
The photographic printer of claim 7 wherein said reciprocal means comprises solenoid means.
