Abstract
A printer automatically discriminates whether a charged microfilm is a negative film or a positive film and reproduces a positive image on a recording sheet from an image recorded on the microfilm. The discrimination between a negative film and a positive film is automatically attained by the detection of the luminous energy of a light traveling through the microfilm and the N-P mode or the P-P mode, whichever conforms to the outcome of the detection, is set. The kind of film found by the discrimination is displayed on a display part. Then the key operation is made after the copying performed under the automatically set mode is completed, the existent mode is switched to the opposite mode. By the key input, the operator is allowed to set either of the modes mentioned above. Even when the judgment on the kind of film yields an erroneous result, the number of incorrect copies can be minimized by a simple procedure.
