Abstract
Abstract A method and apparatus for maintaining correlation between the parts of a film processing order from its receipt in a lab to its assembly for return to the customer includes placing a machine-readable identifier on the film, envelope and prints. The identifiers are read at the point of final order assembly and if any identifiers are not readable an error counter is incremented. If the error counter reaches a predetermined maximum number, an alarm is given and the operation is halted for operator intervention. If the maximum error number is not reached, the identifiers read at the finishing station are compared for equality. If there is a mismatch between identifiers, an alarm is given and the operation halted for operator intervention. Each time an order is successfully processed with no misreads, the error counter is decremented by some predetermined number. In a predetermined embodiment, the error counter is reset after each operation intervention.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
The method of checking correlation between all parts of a photofinishing order during processing comprising the steps of: (a) providing each part of the order with a machine-readable common identifier, (b) reading the identifier from each part, (c) determining if each identifier is readable, (d) resetting an error flag for each unreadable identifier, (e) comparing the number of error flags set with a predetermined number and if the error flags exceed the predetermined number initiating a corrective action, and (f) if the error flags do not exceed the predetermined number comparing the identifiers with one another and if all identifiers match continuing the processing, if any one of the identifiers does not match initiating corrective action.
Claim 2
Independent Claim
116 words
The method of checking correlation between all parts of a photofinishing order during processing comprising the steps of: (a) providing each part of the order with a machine-readable common identifier, (b) reading the identifier from each part, (c) determining if each identifier is readable, (d) resetting an error flag for each unreadable identifier, (e) comparing the number of error flags set with a predetermined number and if the error flags exceed the predetermined number initiating a corrective action, and (f) if the error flags do not exceed the predetermined number comparing the identifiers with one another and if all identifiers match continuing the processing, if any one of the identifiers does not match initiating corrective action.
Claim 3
Dependent Claim
29 words
The method of claim 1 further including the step of decrementing the error counter by a predetermined number each time all the parts of the order contain reaable identifiers.
Claim 4
Dependent Claim
25 words
The method of claim 2 further including the step of displaying an error message each time one of the identifiers is determined to be unreadable.
Claim 5
Dependent Claim
25 words
The method of claim 3 further including the step of resetting the error counter to zero each time the maximum number of errors is reached.
Claim 6
Independent Claim
88 words
The method of analyzing errors in a process including the steps of: (a) detecting a first type of error, (b) incrementing an error counter for each detected first type error, (c) interrupting the process when the error counter reaches a first predetermined number, (d) decrementing the error counter by a second predetermined number for each successful completion of the process occurring between detected first type errors, and (e) detecting errors of a second type and interrupting the process upon occurrence of a single error of the second type.
Claim 7
Independent Claim
88 words
The method of analyzing errors in a process including the steps of: (a) detecting a first type of error, (b) incrementing an error counter for each detected first type error, (c) interrupting the process when the error counter reaches a first predetermined number, (d) decrementing the error counter by a second predetermined number for each successful completion of the process occurring between detected first type errors, and (e) detecting errors of a second type and interrupting the process upon occurrence of a single error of the second type.
Claim 8
Dependent Claim
25 words
The method of claim 5, wherein the error counter is reset to zero upon each successful completion of the process between detected first type errors.
Claim 9
Dependent Claim
128 words
A film processing apparatus including: means for providing a machine-readable identification on a film, envelope and photographic prints, means for reading said machine-readable identifiers from said film, envelope and prints; means for sensing a non-read of any one of said identifiers and producing an error signal representative of said non-read; error counter means for receiving said error signal and incrementing a number in said counter upon receipt of said error signal; first comparator means for comparing the contents of said error counter to a first predetermined number and producing an alarm signal if said contents equals or exceeds said first predetermined number; second comparator means for comparing the identifiers and producing an alarm signal if any one of the identifiers is not the same as the other identifiers.
Claim 10
Dependent Claim
128 words
A film processing apparatus including: means for providing a machine-readable identification on a film, envelope and photographic prints, means for reading said machine-readable identifiers from said film, envelope and prints; means for sensing a non-read of any one of said identifiers and producing an error signal representative of said non-read; error counter means for receiving said error signal and incrementing a number in said counter upon receipt of said error signal; first comparator means for comparing the contents of said error counter to a first predetermined number and producing an alarm signal if said contents equals or exceeds said first predetermined number; second comparator means for comparing the identifiers and producing an alarm signal if any one of the identifiers is not the same as the other identifiers.
Claim 11
Dependent Claim
36 words
The apparatus of claim 7, further including: decrementing means associated with said error counter and operable to decrement the number in said error counter by a second predetermined number each time said identifiers are all readable.
