Abstract

PURPOSE:To calculate and display the number of originals which can be photographed on an unexposed film detecting the amount of the unexposed film and by dividing it by the feed extent of the film per original that corresponds to the size of the original. CONSTITUTION:Pulses that a pulse generator generates by coupling with the film feed of an exposure part are counted to store RAM102 with the count value that corresponds to the amount of an exposed film. On the other hand, the feed extent of the film per original size is stored in ROM103. The difference between the set amount of the film stored in ROM103 and that stored in RAM102 is calculated by the substraction part of CPU100 and the value is stored in RAM102. This stored substraction value is divided by the memory value of ROM103 stored with the feed extent of the film per original that corresponds to the size of the original selected with selection switch 7, and the division value is displayed on display device 104.
