Abstract
A photographic printer having a roof type mirror with a reflection surface of a roof type. The roof mirror is disposed at a 45 degree angle relative to the optical axis of the printing lens. Incident light is reflected twice by the roof mirror, and thereafter it reaches either a photosensitive material disposed at the focal plane of the printing lens, or a monitor screen. The roof mirror reverses the right and left sides of an image so that the right and left sides of an image projected upon the monitor screen or photosensitive material are the same as those of an original image of the photographic film. In a preferred embodiment, when the roof type mirror is inserted within the printing optical path, the light reflected by the roof type mirror reaches a first exposure station, and when the roof type mirror is retracted from the printing optical path, the light passed through the printing lens reaches a second exposure station.
