PURPOSE:To remove labor and trouble for the formation of a date sheet at every day and to make the management of data or the like easy by automatically transferring a date to a film every photographing date. CONSTITUTION:A data transfer mechanism 21 is arranged between a guide roller and a capstan roller of a rotary camera and electric power is supplied from a backup power supply 25 to a clock circuit 24 to display an accurate data on a liquid crystal plate 22 independently of OFF of a power supply switch of the camera. When a data is to be changed at 0 a.m., a data detecting circuit 26 is driven and the 1st FF circuit 27 is set up. The 2nd FF circuit 39 is set up by the output of the circuit 27 and a detecting signal of a data detecting circuit 29. At the time of turning on a power supply switch, a reset pulse is generated from an initial reset circuit 28 and applied to an OR circuit 34a constituting a state holding circuit. A film carrying driving circuit 36 and a date transfer circuit 35 are controlled on the basis of the outputs of the circuits 27, 29 to automatically write a date in a film at every photographing date.
