Abstract
Abstract A film merging unit that automatically updates an old master film with data contained on an updating film by producing a new film with the old and the new data correctly merged thereon. A control device is present for reading a control strip containing coded marks and producing control signals to activate selected drive mechanism to sequence the relative positionings of the films with respect to the printing station.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A film merging unit for merging data on a master film and data on an updating film onto a raw film to produce a new updated film, comprising in combination, a printing station for transferring data from said master film onto said raw film and for transferring data from said updating film onto said raw film, a plurality of drive means, one for each of said films, control means for reading a control strip containing coded control marks to produce control signals, and means for applying said control signals to activate selected ones of said drive means to sequence the relative positionings of said films with respect to said printing station for controlling the order in which said data are transferred to said raw film.
Claim 2
Dependent Claim
125 words
A film merging unit for merging data on a master film and data on an updating film onto a raw film to produce a new updated film, comprising in combination, a printing station for transferring data from said master film onto said raw film and for transferring data from said updating film onto said raw film, a plurality of drive means, one for each of said films, control means for reading a control strip containing coded control marks to produce control signals, and means for applying said control signals to activate selected ones of said drive means to sequence the relative positionings of said films with respect to said printing station for controlling the order in which said data are transferred to said raw film.
Claim 3
Dependent Claim
41 words
The combination in accordance with claim 1 wherein said control means comprises a reading station for reading said coded control marks from said control strip, and a control electronic unit for decoding said coded control marks to provide said control signals.
Claim 4
Dependent Claim
17 words
The combination in accordance with claim 2 wherein said data is recorded on said films by frames.
Claim 5
Dependent Claim
41 words
The combination in accordance with claim 3 wherein said drive means includes an incremental drive attachment for driving said films in incremental steps substantially equal to a data frame length so that frames of data are transferred onto said raw film.
Claim 6
Dependent Claim
67 words
The combination in accordance with claim 2 wherein said control strip containing said coded control marks is incorporated onto one of said films, and data from said master film are transferred to said raw film on one pass of said films through said printing station and data from said updating film are transferred to said raw film on another pass of said films through said printing station.
Claim 7
Dependent Claim
44 words
The combination in accordance with claim 2 wherein said control strip is separated from said films to control the transfer of data from said master film and said updating film onto said raw film on one pass of said films through said printing station.
