Claims (1)

[Scope of Claim for Utility Model Registration] An exhaust duct that is piped to have an air outlet and an air intake at a predetermined position inside a copying machine, and an air outlet and exhaust system in which these exhaust ducts are connected to perform exhaust air in a concentrated manner. A cleaning device for a copying machine, comprising: a cleaning duct that is piped from the air supply/exhaust device and has a connection port at the tip for sucking air for cleaning; and a cleaning duct that is housed in the copying machine and is used for cleaning. a duct with a removable suction nozzle that can be arbitrarily connected to a connection port of the duct to clean the inside and outside of the copying machine, and usually the exhaust flow path of the ventilation device is connected to the exhaust duct; A cleaning device for a copying machine, comprising a ventilation mode switching means for switching and connecting the exhaust flow path to the cleaning duct when the suction nozzle-equipped duct is connected to the connection port.
