FILTER CARTRIDGE FOR WET ELECTRONIC PHOTOGRAPH PRINTER

摘要

PURPOSE: A filter cartridge for a wet electronic photograph printer is provided to continuously pressurize the activated carbon and prevent channeling by preventing the pressurizing member from being pushed backward by external force. CONSTITUTION: Activated carbon is filled into a cylindrical cartridge body(11). A plastic pressurizing member pressurizes the active carbon. A disc-type pressurizing member has a hole at the center where the end of a filter pipe(12) is seated. There are several air passing holes around this hole. There are the first and the second contact ribs around the outer circumference of the disc. The first contact rib is expanded backward and it makes the pressurizing member not be pushed backward by an external force.
