A laser computer output microfilm camera for utilization of direct read after write film comprises a film gate, device for transporting a film in the film gate in stepped manner in one direction, device for moving the film gate normal to the one direction and parallel to a film plane also in a stepped manner, film supply device for supplying a film into the film gate, device for receiving a ready to use microfiche produced from the film, device for deviating a laser beam in the region of an image field of a microfiche image from the beginning of lines to the end of lines and back, and to a next line and back, objective device for projecting the laser beam onto the film gate or onto a film contained in the latter, the film supply device being formed as at least partially open stable container in which the film as a microfiche sheet film is stored in a stack, withdrawing device for withdrawing the film from the stable container and then transporting to the device for transporting the film, the stable container being immovable, and control device arranged to control the movement of the film gate, the transportation of sheet film in the film gate, the return of the film gate after production of the a microfiche to a loading position associated with the stable container, the control device being formed as a single control device.

An original holding plate element for a reproduction device has a flexible body part with a lower surface facing toward an original, and a white paper layer which has an inner surface facing toward and connected with the lower surface of the body part, and an outer surface facing away of the same and lined with a pellucid synthetic plastic foil.

Plate element for holding an original, in a reproduction device

A cascade-type developing unit for an electrostatic copying apparatus is disclosed. A mixture of toner and carrier particles circulates in the unit and its particles become electrostatically charged due to electrification. An arrangement is provided for limiting the charge of the particles to user-selectable values.

Electrostatic copying apparatus

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.
