Abstract: An apparatus for monitoring photographic processing liquid composed of a timer to determine the length of time which has passed after the renewal of the processing liquid, a counter to determine the amount of the photographic film which has been already processed and an alarm light which is responsive to either timer or counter when having reached the respective predetermined position for lighting to indicate that the photographic processing liquid must be renewed. Thanks to the monitoring in terms of the "effective length of time" of the processing liquid and of the total amount of the photographic film already processed, it is assured that the processing liquid is renewed before it has been exhausted and has lost the processing capability.

Abstract: A microfilm inserter having a table for retaining a microfilm jacket in a fixed position is provided with a pair of feed rolls at either end of the table, a detecting means for detecting the trailing end of a microfilm strip to be inserted into said jacket, and a cutter for cutting off the leader of said microfilm strip. A film strip having a leader is fed through the feed rolls at one end and into the insertion slot of the jacket. When the leader exits from the far end of the jacket, it passes between the other pair of rolls and the film strip continues to be transported even after the trailing end thereof has passed through the feed rolls at said one end. When it is detected that the trailing end of the film strip has arrived at a predetermined position, the film strip is stopped and the leader is cut off along the far end of the jacket.
