ELECTROSTATIC COPYING MACHINE HAVING FLASH-DISCHARGE- LAMP-FIXING UNIT

摘要

ELECTROSTATIC COPYING MACHINE HAVING FLASH-DISCHARGE-LAMP FIXING UNIT 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 coolingair stream of low volumetric flow rate. A second coolingair 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.
