ABSTRACT:
A color balance measuring device for regulating color balance in a photographic printer in which color images recorded on a film are printed onto photographic paper to obtain photographic prints. In the color balance measuring device, a density measuring portion and a pusher member, which is movable in a direction of the density measuring portion, are provided opposing each other with a transport path of the photographic prints interposed therebetween. The density measuring portion and the pusher member are disposed at predetermined distances with respect to surfaces of the photographic prints. A white reference plate is provided at a density measuring portion side of the pusher member. The density measuring portion is pushed via the white reference plate by movement of the pusher member. Because the density measuring portion and the pusher member are provided so as to be separated from the transport path, the density measuring portion and the pusher member do not contact the photographic prints which are being transported, and do not damage the surfaces of the photographic prints.
