PURPOSE:To realize a compact and light-weight structure and to improve the reliability for a time display, etc., by decreasing the number of parts which are mechanically actuated and having the electrical processing. CONSTITUTION:A slit photographing device A contains a slit plate 2 behind which a film 6 travls and a light shielding blade 7 which is driven in front of the plate 2 and photographs a decision line on the film 6. A light emitting material 16 for time characters provided within a time/data display B emits light instantaneously with the electric pulse supplied from a timepiece device C. While a light emitting material 17 for date characters emits light instantaneously with the electric pulse supplied from a date setting device D. Flash light materials 19 and 20 emits flash light with electric pulses of different frequencies which are supplied from the device C. Then the desired date and time as well as a photosensitive line for decision are displayed on the film 6. |
