A lamp of low ozone generation is used as the flash lamp, to minimize the amount of ozone reaching the machine exterior. A first cooling-air passage includes the space surrounding the flash lamp and its reflector and is provided downstream thereof with an activated-carbon filter, from which is discharged a quite hot first cooling-air stream of low volumetric flow rate. A second cooling-air stream emerging from the electronics compartment of the machine is much cooler and cleaner and of high volumetric flow rate. The first and second cooling-air streams are mixed together, to dilute and cool the first, prior to actual discharge to the machine exterior. The mixed air streams are discharged in downwards direction.

Electrostatic copying machine having flash-discharge-lamp fixing unit

The flash discharge lamp is energized by the discharge of a battery of flash condensors. When an attempt is made to gain access to the flash condensors, these are automatically and quickly discharged through current-limiting resistors, to preclude the danger of electrocution. The fixing station of the copying machine, including the flash discharge lamp, the battery of flash condensors, the transport rollers which transport copying medium through the fixing station and almost all of the electronic control circuitry of the fixing station, are provided on a single housing, removable from the copying machine as a pull-out unit.
