PURPOSE:To insure a light source against getting wet by a rocking solution at the time of pulling out a treatment tank by separating the light source in an exposure means from a development tank and containing said source in a lamp house above the surface of the solution. CONSTITUTION:An inversion and exposure means 42 inverts and exposes the photosensitive material carried in the 1st developer tank. Light from the light source 424 in the lamp house 423 on the lower surface of a light shielding boxy 39 on the upper part is projected on the photosensitive material through the exposure window 421. The lamp house 423 is provided above the solution surfaces of the treatment tanks 41A-41E. When they are removed outside for checking, the lamp house still stays in the device and never soaked due to the rocking of the solution surface of the tank. Accordingly replacement work in the lamp house can be facilitated.
