Abstract: The invention relates to a method and an apparatus for cleaning from the outer surface of an endless transport belt the ink, not ejected for printing purposes, of an inkjet printer, said method and apparatus serving for completely removing and collecting the ink adhering to the transport belt, while retaining a high transport belt speed. The method is characterized by the application of a converging compressed-air stream onto the outer surface of the ink-wetted transport belt by means of an air conduit, comprising a suction nozzle, of a pressure nozzle, and by extraction of the resulting ink-air mixture by means of the suction nozzle, the two steps being performed simultaneously.

Abstract: An ink jet printer for making photographic prints includes at least one paper supply for holding a supply of print paper and a sheet paper transport belt arranged to receive sheets of print paper from the at least one paper supply and transport the sheets through the printer. A back printer is located between the paper supply and the paper transport belt for applying back prints to the print paper. A full print width color ink jet print head is located over a first portion of the transport belt for printing an image on a paper sheet. A paper support located under the ink jet print head is provided with ink overspill collection grooves to collect overspilled ink from the ink jet print head.

Abstract: The invention relates to an endless transport belt for receiving ink, not ejected for printing purposes, of an inkjet printer; said transport belt receiving the ink sprayed thereon during printing of printing material in such a manner that smearing on the back side of the paper is prevented. For this purpose, the transport belt comprises a carrier layer and a support layer for supporting and printing printing materials of differing widths and lengths by means of an inkjet print head, the support layer according to the present invention having a knobbed grid structure with a hydrophobic and ink-rejecting coating.

Abstract: A viewfinder mask, viewfinder and photographic camera. The viewfinder mask connects to a camera lens for adjusting the image field of the viewfinder to the adjustable focal length of the camera lens. The viewfinder mask comprises an L-shaped frame part and a rectangular frame part covering the latter, these being linked by a film hinge. A guide lever engages on the one hand a corner of the rectangular frame part and on the other hand, in the area of the film hinge, the L-shaped frame part. The frame parts are mounted movably in relation to one another inside the case.

Abstract: The invention relates to a sealing arrangement for a shutter release and film transport control element of a photographic camera, having an outer watertight body which has an opening for receiving the shutter release and film transport control element using which a rotational film transport and a transversal shutter release movement can be transmitted to corresponding control elements of a camera arranged inside said body, where a single one-piece sealing element is provided for transmitting the shutter release and film transport movement, by which sealing element the opening can be sealed watertight.

Abstract: The invention relates to a film transport and release device for a photographic camera comprising a body part that pulls out and slides in parallel to the film transport direction in relation to the camera body, where in the pulled-out position of the body part the camera is ready to take a picture. Furthermore, a film transport wheel for a perforated film strip is provided. The body part has a toothed rack which is assigned a toothed wheel mounted permanently on a driving arbor arranged in axially movable and non-rotatable manner in the film transport wheel. Here the toothed wheel is movable by means of the release into its ready-to-mesh position in relation to the toothed rack and is kept in this position after operation of the release until the film strip has been transported one picture field further.

Abstract: The invention relates to a method and apparatus for measuring the rotary movement of a shaft, wherein according to said method a magnetic pattern radially applied to a magnetic disk is inductively scanned so that in a magnetic head voltage pulses are generated which are associated with the magnetic pattern and used for determining the rotary movement and the angular position of a rotating object. To realize a measuring arrangement featuring a selectable measuring resolution, by means of a read/write head at least one magnetic pattern is radially applied with a randomly selectable recording density to the magnetic disk connected to the shaft to be measured, said pattern being then inductively scanned at a constant rotational speed of the read/write head as the magnetic disk is at rest. From the induced voltage pulses the read/write head speed is computed by electronic means and stored.
