ABSTRACT:
A printer film carrier turning apparatus for obtaining a photograph by irradiating light onto a film comprises a film carrier for supporting the film, a carrier supporting table for supporting the film carrier parallel with the film to make the film carrier turn through a 90.degree. range, and a light diffusion box for diffusing illuminance light to uniformly illuminate a film range which is to be printed. The film turning apparatus is constructed such that the film carrier turns in unison with the light diffusion box. Therefore, transferring rollers of the film carrier cannot interfere with the light diffusion box, which allows the light diffusion box to be placed very close to the film carrier and thereby increases the efficiency of the light source. Also, the film carrier can be turned in unison with the light diffusion box, thereby improving the operating mechanism.
