Abstract
Abstract A photographic copier in which originals copied at a copying station are first examined to determine the type of corrections to be applied to the illuminating source used in copying the original. The corrections are applied by operating personnel at an examining station in front of the copying station. A transport unit with buffer moves the originals from the examining station to the copying station. An information memory stores the corrections to be applied to the originals, until the respective original arrives at the copying station and is in position to be copied.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
150 words
A copying arrangement, comprising iN combination a copying station including copying means for copying originals; an examining station for placing a batch of n originals to be copied simultaneously on view for visual inspection by an operator; exposure-correction setting means at said examining station for setting exposure-correction values for originals viewed at said examining station; storage means for storing originals to be copied; first transport means for transporting batches of n originals periodically and with a first frequency through said examining station for batchwise inspection and thereafter into said storage means; second transport means for transporting originals numbering less than n periodically and with a second higher frequency from said storage means into said copying station; and control means cooperating with said setting means for applying said exposure-correction values to said copying means in coordination with the arrival at said copying station of the respective originals associated with such values.
Claim 2
Dependent Claim
150 words
A copying arrangement, comprising iN combination a copying station including copying means for copying originals; an examining station for placing a batch of n originals to be copied simultaneously on view for visual inspection by an operator; exposure-correction setting means at said examining station for setting exposure-correction values for originals viewed at said examining station; storage means for storing originals to be copied; first transport means for transporting batches of n originals periodically and with a first frequency through said examining station for batchwise inspection and thereafter into said storage means; second transport means for transporting originals numbering less than n periodically and with a second higher frequency from said storage means into said copying station; and control means cooperating with said setting means for applying said exposure-correction values to said copying means in coordination with the arrival at said copying station of the respective originals associated with such values.
Claim 3
Dependent Claim
76 words
The copying arrangement as defined in claim 1 including sensing means at the entrance of said examining station for sensing the passage of said originals into said examining station; counter means connected to said sensing means and counting the number of originals sensed by said sensing means; and stopping means connecting said counter means to said first transport means for stopping the latter when a predetermined number of originals have been sensed by said sensing means.
Claim 4
Dependent Claim
37 words
An arrangement as defined in claim 1, wherein said exposure-correction setting means comprises n distinct setting means located at said examining station and spatially disposed in correspondence to the disposition of originals displayed at said examining station.
Claim 5
Dependent Claim
52 words
An arrangement as defined in claim 2, including second counting means for counting the number of originals passing into said copying station; and means connecting said second counting means to said first transport means for re-initiating operation of the latter when a predetermined number of originals have passed into said copying station.
Claim 6
Dependent Claim
120 words
An arrangement as defined in claim 3, wherein said control means comprises a first memory connected to said n distinct setting means, operative during the stay of one batch of originals at said examining station, for registering the respective exposure-correction values in individually resettable manner, whereby to permit rectifying of wrongly set values during the stay of the respective batch at said examining station, and also a second memory, operative at the end of the stay of a batch at said examining station, for registering the exposure-correction values registered in said first memory and for subsequently transmitting such values to said copying means in coordination with the arrival at said copying means of the respective originals associated with such values.
Claim 7
Dependent Claim
34 words
The copying arrangement as defined in claim 5 wherein said values are transferred in parallel from said first memory to said second memory, said transfer taking place so that all values are transferred simultaneously.
Claim 8
Dependent Claim
23 words
The copying arrangement as defined in claim 5, said second memory having a memory capacity corresponding to the capacity of said storage means.
Claim 9
Dependent Claim
40 words
An arrangement as defined in claim 5, wherein said control means comprises electronic logic circuitry, said second memory being a shift register, and means for triggering said shift register once each time an original is copied by said copying means.
Claim 10
Dependent Claim
47 words
An arrangement as defined in claim 8, wherein said shift register comprises a plurality of memory units arranged in succession, and wherein said control means further comprises means for causing the first of said shift register memory units to register a value distinguishable from said exposure-correction values.
Claim 11
Dependent Claim
110 words
An arrangement as defined in claim 9, the originals to be copied being arranged in strips connected by splices to form longer strips, and said first memory having n memory cells; and further including synchronizing means comprising splice detector means at said copying station for detecting the arrival of a splice, splice registering means, operative when a splice is located at said examining station, for causing a respective one of said memory cells of said first memory to register a ''''splice'''' value representative of the existence of a splice, and ''''splice'''' value detector means responsive to registration of a ''''splice'''' value by the last memory cell of said shift register.
Claim 12
Dependent Claim
79 words
An arrangement as defined in claim 10, said synchronizing means further comprising compensation means for terminating triggering of said shift register when the last memory cell of said shift register registers a ''''splice'''' value without said splice detector means detecting the arrival of a splice, and for effecting additional triggering of said shift register when said splice detector means detects arrival of a splice without registration of a ''''splice'''' value by the last memory cell of said shift register.
Claim 13
Dependent Claim
47 words
An arrangement as defined in claim 11, wherein said compensation means is further operative for overriding any exposure-correction values applied to said copying means when said last cell of said shift register registers a ''''splice'''' value without said splice detector means detecting the arrival of a splice.
Claim 14
Dependent Claim
47 words
An arrangement as defined in claim 10, wherein said splice registering means includes auxiliary counting means operative for counting the number of originals entering said examining station from the time of entry of a splice until the stopping of said first transport means by said stopping means.
