PURPOSE: To obtain a hard copy by using reflected or transmitted light by writing characters, etc., on a film with a pencil, etc., projecting light upon the film through a slit, and moving the film successively.
CONSTITUTION: Characters are written on the film 8 extended between shafts 7 by using a pencil, ball-point pen, etc. When a copy key 14 is pressed, a light source 10 turns on to project the light upon the film 8 through the slit 11, and its reflected light is detected by a detection part 122 to print the characters on a copy form 13 through a printing circuit 123. When the printing circuit 123 recognizes characters to the width of the slit 11, a control signal is supplied to a rotation control part 12 for the shafts 7, which are rotated to move the film 8 by the width of the slit 11. This operation is repeated until the film moves by the interval of the shafts 7. The light source 10 is turned on by detecting the completion and the copying operation is ended.
