Photographic printing apparatus

摘要

A photographic printing apparatus for diffusing light emitted from a light source and irradiating a negative film with the light diffused has a body for accommodating a light source, a case which is attached to the accommodating body for swinging motion between an exposure-light guiding position and an out-of-optical-path position, and a diffuser box which is detachably attached to the case. With this arrangement, when a diffuser box is to be replaced in order to employ a negative film of different size, the diffuser box can be mounted without the need to detach the case.
