Abstract
A waste solution discharging apparatus for waterless lithographic printing plates which is used in a waterless lithographic printing plate developing apparatus, in which a waterless lithographic printing plate is developed while processing solution inside an accommodating tank is pumped out by a circulating pump, supplied to the waterless lithographic printing plate, and recovered in the accommodating tank, and a replenishing solution is replenished periodically. The waste solution discharging apparatus for waterless lithographic printing plates discharges the processing solution, which is within the accommodating tank and which contains scrapings generated after development, as waste solution. In the waste solution discharging apparatus for waterless lithographic printing plates, a processing solution inflow opening of a discharge pipe, which discharges the processing solution in the processing tank along with the scrapings, is formed of a material having low surface tension, and/or the waste solution discharging apparatus is provided with a guide member which guides the scrapings to the processing solution inflow opening. Accordingly, the processing solution which includes the scrapings smoothly flows into the discharge pipe.
