Document Type and Number:
Japanese Patent JP3061473
Kind Code:
B2
Abstract:
A data printing apparatus of this invention controls the emission timing or the emission interval of a light-emitting means on the basis of a signal according to traveling of a sheet film along a traveling path so as to print data free from blurring of characters or a variation in interval between characters on the sheet film having no perforations. After an exposure operation is ended, the apparatus feeds the sheet film from an exposure position along a spool wall. Light corresponding to digital numerals representing a date is emitted by light-emitting elements, and the date to be printed by the light-emitting elements is focused on the sheet film by an optical system. The date on the sheet film is printed during traveling of the sheet film along the spool wall. The apparatus also includes a photoreflector, arranged in a traveling chamber of the film, for detecting an emulsion portion on which an object image from a photographing lens is exposed, and the remaining frame portion on the basis of a difference in reflectance, and a timer for measuring a moving time from when the frame portion is detected by the photoreflector until the emulsion portion is detected thereby, and controls the emission timings of the light-emitting elements on the basis of the moving time.
