PURPOSE:To use not only a negative film of any length but also a negative film having no perforation and a photosensitive material by shifting the negative film by utilizing a frictional force to the photosensitive material. CONSTITUTION:A titled device is provided with a supply magazine 1 of a printing roll-shaped photosensitive material, a winding magazine 2, an exposing and driving part 3, an inserting port 4 of a negative film, a discharge port 5, and a start switch 6 of a printing work. When the tip part of a negative film 20 is pushed into the device from the inserting port 4 with its film surface up, its tip is guided by a guide material 16, and placed between a photosensitive material 7 and a guide means 9. In this state, when the start switch 6 is turned on, a light source 15 is lighted, also a driving roller 11 rotates and the photosensitive material 7 is shifted, and the negative film 20 also contacts tightly to the photosensitive material 7 and advances by a frictional force of its film surface and an emulsion surface of the photosensitive material 7, and is discharged from the discharge port 5. When the photosensitive material 7 and the negative film 20 contact tightly and advance along a curved guide part 9a, a picture of the negative film 20 is made to contact tightly to the photosensitive material 7 and exposed by a light of the light source 15 irradiated from an exposing opening 9b.
