Abstract: A liquid developing equipment for electrophotographic copying machines to carry a photosensitive sheet to the flow of developing solution between tilted and opposing electrode plates, comprising a developing solution storage tank at the upstream of the flow channel and a developing solution discharge outlet positioned facing to the latent image surface of the photosensitive sheet.

Abstract: Disclosed is a copying machine for use in photomechanical process, which has a substantially box-shaped structure in appearance and employs a slit exposure system. A sensitive material is transferred along the ceiling surface, side wall and bottom surface of the box-shaped body of the machine in this order so that it can be exposed, developed and dried successively while it is being transferred. A slit exposure scanner makes reciprocatory movements horizontally in a space between an exposure zone positioned below the ceiling surface where the sensitive material is exposed while it is transferred horizontally along the ceiling surface and an original picture stand arranged immediately below the exposure zone so as to oppose thereto. On the bottom surface of the body, there are arranged a development tank, drying means, and a take-out tray for taking out the sensitive material after developed and dried.
