FILM INFORMATION WRITING DEVICE, FILM INFORMATION READING DEVCIE AND FILM INFORMATION HANDLING DEVICE

The present invention provides a device and method for enabling the writing of a print format and a trimming magnification onto a film surface using a simple construction. Film information comprising a print format set using a format setting switch 10 and a trimming magnification set using a trimming setting switch 11 is converted into three-bit data by a data conversion circuit 26 inside a controller 25. This information is input to an LED light emission controller 27. Photoemitter elements 17 and 18 are located in the feeding path for the top and bottom edge areas of the film F, and a LED light emission controller 27 causes the photoemitter elements 17 and 18 to emit light during a series of image recording operations, whereby the film information is written onto the top and bottom edge areas of the film F. By optically writing the print format information and the trimming information onto the film F, both items of information can be easily written onto the film surface without making the device complex.
