Abstract
Abstract A photographic print marker for placing index marks on a strip of photographic paper, for use by an automatic trimmer, includes a pair of essentially identical markers, one of which forms marks corresponding to the location of the individual prints while the other forms index marks corresponding to the beginning or the end of an order. The print marker is particularly useful in the making of borderless color prints in automatic photographic printing apparatus, and incorporates ball point pens which are mounted on a drive mechanism. The drive mechanism employs an electric solenoid which brings the ball point pen into contact with the paper, in a cycle of operation, to provide an index mark on the back surface of the paper. The pen cartridge is mounted in a holder which provides for axial movement of the pen once it has come into contact with the paper, so that a straight line is made by a rotary drive apparatus. The marker also includes provision for adjusting the position of the pen in relation to the width of the paper, for adjusting the length of the mark which is made, and for adjusting the pressure of the pen on the paper.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
A photographic print marker for placing index marks on continuous lengths of photographic paper for use by an automatic trimmer in trimming the individual prints therefrom, comprising in combination means forming a path over which said paper moves during printing, a ball point pen, means supporting said pen in adjacent relation to said paper including a rotatable support in which said pen is mounted in offset relation to the axis of rotation, means connected to rotate said pen support to bring said pen into contact with the back side of said paper adjacent the edge thereof and to cause said pen to move in a direction transverse to the length of said paper to provide a trim index mark on the paper in relation to an image thereon, which mark is impervious to the developing chemicals.
Claim 2
Dependent Claim
136 words
A photographic print marker for placing index marks on continuous lengths of photographic paper for use by an automatic trimmer in trimming the individual prints therefrom, comprising in combination means forming a path over which said paper moves during printing, a ball point pen, means supporting said pen in adjacent relation to said paper including a rotatable support in which said pen is mounted in offset relation to the axis of rotation, means connected to rotate said pen support to bring said pen into contact with the back side of said paper adjacent the edge thereof and to cause said pen to move in a direction transverse to the length of said paper to provide a trim index mark on the paper in relation to an image thereon, which mark is impervious to the developing chemicals.
Claim 3
Dependent Claim
35 words
The marker of claim 1 in which said mounting means provides for limited movement of said pen in a direction along the length of the pen when said pen comes into contact with the paper.
Claim 4
Dependent Claim
170 words
A photographic print marker for placing index marks on a continuous strip of photographic paper for use by an automatic trimmer to sever the strip into individual prints corresponding to the location of an image thereon, comprising in combination a ball point pen, mounting means for said pen including spring bias means urging said pen toward the back surface of said paper and resiliently providing for axial movement of said pen relative to said pen support, a rotating pen drive, said pen support being mounted in offset relation to the axis of said drive to be brought into contact with said strip and moved transversely of said paper with rotation of said drive, a rotary solenoid connected to rotate said pen drive upon energization in a cycle of operation to bring said pen into engagement with said strip followed by transverse movement of said pen against said strip to place an index mark thereon, said rotary solenoid being spring biased to return said pen to its rest position upon de-energization.
Claim 5
Dependent Claim
170 words
A photographic print marker for placing index marks on a continuous strip of photographic paper for use by an automatic trimmer to sever the strip into individual prints corresponding to the location of an image thereon, comprising in combination a ball point pen, mounting means for said pen including spring bias means urging said pen toward the back surface of said paper and resiliently providing for axial movement of said pen relative to said pen support, a rotating pen drive, said pen support being mounted in offset relation to the axis of said drive to be brought into contact with said strip and moved transversely of said paper with rotation of said drive, a rotary solenoid connected to rotate said pen drive upon energization in a cycle of operation to bring said pen into engagement with said strip followed by transverse movement of said pen against said strip to place an index mark thereon, said rotary solenoid being spring biased to return said pen to its rest position upon de-energization.
Claim 6
Dependent Claim
155 words
An automatic marker for marking borderless prints for use by a trimming apparatus comprising a ball point pen cartridge, a cartridge holder for supporting said pen cartridge with the ball thereof spaced from the back surface of the paper, means in said holder providing for axial movement of said cartridge therein, eccentric drive means for said holder including a a block adjustable positioned on said holder, a drive shaft, means mounting said block in offset relation to said shaft to be driven by rotation of said shaft to bring the tip of said cartridge into contact with said paper followed by movement across said paper to form a mark thereon, and a rotary solenoid connected to rotate said drive shaft in a cycle of operation to bring the tip of said cartridge into contact with the paper and to return said holder to its starting position to form a double-traced index mark on said paper.
Claim 7
Dependent Claim
155 words
An automatic marker for marking borderless prints for use by a trimming apparatus comprising a ball point pen cartridge, a cartridge holder for supporting said pen cartridge with the ball thereof spaced from the back surface of the paper, means in said holder providing for axial movement of said cartridge therein, eccentric drive means for said holder including a a block adjustable positioned on said holder, a drive shaft, means mounting said block in offset relation to said shaft to be driven by rotation of said shaft to bring the tip of said cartridge into contact with said paper followed by movement across said paper to form a mark thereon, and a rotary solenoid connected to rotate said drive shaft in a cycle of operation to bring the tip of said cartridge into contact with the paper and to return said holder to its starting position to form a double-traced index mark on said paper.
Claim 8
Dependent Claim
42 words
The marker of claim 4 further comprising cap means adjustably mounted on said pen holder, and a compression spring between said cap means and said cartridge urging said cartridge in A direction toward said paper while providing for said axial movement thereof.
Claim 9
Dependent Claim
25 words
The marker of claim 5 further comprising adjustable means engaging said cap means and providing for sliding movement thereof upon the operation of said solenoid.
