付作業性も向上する。According to the present invention, the negative film on which the image to be printed on the photographic paper is recorded is positioned, and when the light source is turned on, the transmitted light from the negative film is reflected by the reflecting surface of the concave mirror, and the image is a visual observation window portion. Be guided to. The concave mirror is magnified with respect to the real image due to the curvature of its reflecting surface and can be viewed, so the number of parts is small and the workability of assembly is low compared to a structure in which a flat reflecting mirror is used to form an image at a predetermined magnification using a convex lens. improves.
また、凹面鏡で反射されたネガフィルムの透過光像は、
大きな範囲に亘って観察でき、若干目視位置がずれても
透過光像の観察が容易となる。In addition, the transmitted light image of the negative film reflected by the concave mirror is
It is possible to observe over a large range, and it becomes easy to observe the transmitted light image even if the visual position is slightly shifted.

Therefore, the enlargement magnification can be changed depending on the selected concave mirror. Here, by selecting a concave mirror according to the mask size of the negative film and setting the size of the image viewed through the visual observation window to a certain size, no matter what size the real image (size of the negative film) is, However, the color correction and the density correction amount can be determined under the same condition.
