Abstract
An automatic film processor for passing an exposed film successively through a series of treating liquid vessels respectively containing developing liquid, fixing liquid and rinsing water is provided. The film processor comprises pump means for forming a constant regular flow to raise a portion of the liquid surface of at least one treating liquid vessel, and flow guide means for guiding the constant regular flow onto the liquid surface, whereby the underside of the exposed film contacts the surface of the raised portion of the liquid. In a modified embodiment, a vibrator for generating an ultrasonic wave is associated with at least one treating liquid vessel for applying ultrasonic vibration to the film so as to accelerate the treating speed.
