Abstract

A first timer unit generates a first time-measurement output by performing a first timer operation. A second timer unit generates a second time-measurement output by performing a second timer operation different from the first timer operation by the first timer unit. A printing unit prints at least one of the first and second time-measurement outputs generated by the first and second timer units on a film upon film exposure.
