To prevent the superposition of print patterns by side printing of a Brownie film and a data imprinting device of a camera.

The print patterns 15a, 15b, 15c and 15d by the side printing are preexposed along the upper end edges when a film strip is laterally drawn out of a spool when viewed from a rear surface side not coated with emulsions. The print patterns 35 exposed by every photographing are imprinted by the data imprinting device of the camera are imprinted along the lower end edge and the superposing thereof on the preexposed print patterns does not occur and therefor these print patterns are easily identifiable.
