Claim 8

A photographic printer wherein a photosensitive material is disposed parallel to a photographic film and an original image recorded in the photographic film is printed on the photosensitive material via a printing lens, said photographic printer comprising: a transparent monitor screen disposed substantially at a right angle relative to said photographic film; roof type reflection means for reversing the right and left sides of an image, said roof type reflection means being set at a first position during monitoring and at a second position during printing, wherein at said first position said roof type reflection means is disposed between said printing lens and said photosensitive material and slanted substantially at a 45 degree angle relative to the optical axis of said printing lens so as to reflect a light passed through said photographic film toward said monitor screen, and wherein at said second position said roof type reflection means is retracted from the optical axis of said printing lens so as not to obstruct a light passed through said photographic film from being directed to said photosensitive material: and driving means for driving and positioning said roof type reflection means at either said first or said second position.

Claim 9

A photographic printer according to claim 4, wherein said roof type reflection means comprises two flat mirrors disposed substantially at right angles to each other.

Claim 10

A photographic printer according to claim 4, wherein said roof type reflection means comprises a prism which is a triangle pole having a right angled isosceles triangle section and having its opposing end surfaces cut off.

Claim 11
