PURPOSE:To simplify the handling of a recorded film by calculating the length of a film which can be fed into a storage room, and by calculating and displaying the number of photographed originals with average length which can be recorded on a film with the calculated length. CONSTITUTION:Pulses equivalent to the length of an exposed film F fed into a storage room 50 and pulses equivalent to the length of the film F discharged from the storage room 50 are counted by a CPU100 respectively and stored in an RAM102. Further, the CPU100 counts the difference E between the maximum length A of the film stored in the storage room 50 and the difference between calculated count values B and C, and it is stored in an RAM102. This difference value E corresponds to the length of the film stored in the storage room 50. The CPU, on the other hand, divides the difference value E by the average length of photographed original stored in the RAM102, and the division value F is displayed on a dispaly device 104, so that the relating originals are photographed on one film. |
