Abstract: A system for loading sheet materials on a rotary drum, having carrier for carrying sheet materials to the drum, a mechanism for catching the leading end of the sheet materials on the drum, and a presser member for pressing the sheet materials to said drum rotating, so as to wind said sheet materials around said drum, wherein said system involves a dampening arrangement for dampening the space between sheet materials and the drum surface, which is mirror finished, so as to contact said sheet materials with said peripheral surface of said drum.

Abstract: An apparatus for producing an electrographic print on a photosensitive receptor placed on a holder so as to produce an electrostatic latent image on the receptor by projecting light thereon, the apparatus including a developing unit located below the receptor holder, the developing unit including a developing section, the developing unit or the receptor holder being movable in relation to the other, the developing section supplying a developer to the sensitive receptor so as to make the electrostatic latent image visible, and a mechanism for collecting the used developer from the sensitive receptor, the collecting mechanism including a pneumatic knife for blowing the used developer on the sensitive receptor to a place of collection, and an arrangement for receiving the used developer brought by the pneumatic knife, the receiving arrangement being provided on that surface of the receptor holder which is outside the sensitive receptor, the receiving arrangement being provided in a direction perpendicularly to t

Abstract: An apparatus for locating a carrier, such as a lens carrier in a process camera unit, exactly at a desired position, the apparatus collecting data of the inertia acting upon the driving system including a motor and a shifting means, and obtaining a mean value from the collected measured values so as to correct the data of inertia in the driving system with the mean value. From the corrected data of inertia an information about the control of the driving system is derived, and applied to locate the carrier at a desired position.

Abstract: An apparatus for producing an electrophotographic print on a photosensitive receptor which is movable through a plurality of predetermined stations so as to produce an electrostatic latent image on the photosensitive receptor, the apparatus including a rotary drum having a peripheral surface which defines an image forming section and a non-image forming section, the photosensitive sheet being placeable on the image forming section of the drum surface, a developing unit having at least one developing section for supplying a developer to the photosensitive sheet on the drum, thereby making the electrostatic latent image visible, and a device for collecting the used developer from the photosensitive sheet, the collecting device being provided axially of the drum in the non-image forming section of the peripheral surface.

Abstract: A photographic fixing apparatus in which photosensitive material to be fixed is fed between upper and lower inclined guideplates, preferably in the form of a plurality of parallel rods, with the lower plate being transparent and with both plates being ventilated to permit the passage of air therethrough. A halogen fixing heater with a quartz filter colored to filter out wavelengths of light to which the photosensitive material is sensitive being provided below the lower guide plate and with a blower being provided to blow air from below the guide plates through the guide plates to maintain photosensitive material passing between the guide plates out of contact with the lower guide plate.
