ABSTRACT:
A camera with a data imprinting device includes a generally triangular space adjacent a film spool. A roller, used to conform the film to the film spool is urged into the triangular space when the film diameter on the roller approaches a maximum diameter. A portion of an optical system for the data imprinting device is also located in the triangular space. The periods of film drive pulses are averaged to establish periods of data imprinting pulses. A plurality of the data imprinting pulses are generated for each film drive pulse. In a full size mode of operation, a first set of the data imprinting pulses are used to record imprinting data. In a panorama mode of operation, a second set of the data imprinting pulses are used to record the imprinting data. The second set of data imprinting pulses contains more data imprinting pulses than the first set of data imprinting pulses, whereby the data imprinted in panorama mode occupies a shorter length of the film than does the data imprinted in full size mode.
