An apparatus for forming a latent image of an identification data in an edge portion of a new photosensitive film is disclosed here. The apparatus comprises editing unit to edit the identification data and an exposure position data, a memory to store the edited data, a register for registering an identification data from the memory and exposing unit to form a latent image of the registered identification data on the photosensitive film based on the exposure position data and synchronized with the feeding of the photosensitive film.

Film data exposure device

An automatically controlled film packaging system which is capable of exposing necessary data as a latent image onto the edges of pre-used film according to the input signal of a unit length required for the merchandise cutting the film into the unit length and taking the film up on a selected patrone, comprising a center processing unit which controls the system automatically when the unit length required is shifted, without any manual re-setting but only by inputting a new unit length of the film required for the merchandise to be produced.

Film processing apparatus

The invention provides an apparatus for optically writing a data onto a non-exposed film being coated with photosensive material while moving the film to a predetermined direction. The data represents a film frame No., photosensitive emulsion lot No. and so on. The apparatus has two groups of LEDs being arranged with a pitch in parallel two lines being crossing at right angles to a film proceeding direction. The disposing position of LEDs on the one line differs by half of the pitch from that on another line. Therefore, the center of light spot on the one of spotted parallel line irradiated on the film does not face with that on another spotted line along the film proceeding direction. Further, the emission timings of the two groups of light emission sources are respectively controlled to have some time lag therebetween, thereby superposing partially the parallel two spotted lines.
