ABSTRACT:
A corona generating device having a corona wire and a shield partially surrounding the wire has an improved built-in cleaning mechanism. The cleaning mechanism includes a cleaning member slidably mounted within the shield, which member is driven back and forth along the device by a belt connected thereto. The belt is driven by a pulley rotatably mounted on the device, the pulley having gear teeth formed therein which are adapted to mesh with a drive gear. By using conventional quick-disconnect electrical connectors to connect the corona wire to a source of voltage, and a suitable supporting member to both support the device and position the pulley so that it meshes with the drive gear, the device can be easily removed from an electrostatic reproduction machine for routine maintenance, and easily inserted back into the machine.
