An apparatus is provided for mounting a pellicle to a photomask. A chamber has at least one port for filling the chamber with extreme clean dry air (XCDA) or an inert gas. A pellicle mounter is provided within the chamber. The mask is irradiated with a vacuum ultra violet (VUV) light in an atmosphere of the XCDA or inert gas, and the pellicle is mounted to the mask while the mask is in the atmosphere of the XCDA or inert gas and exposed to the VUV light. An assembly includes the mask attached to a pellicle frame by a pressure sensitive adhesive; and a pellicle joined to the pellicle frame, forming a sealed enclosure, the sealed enclosure being filled with extreme clean dry air (XCDA) or inert gas.

A chamber assembly (26) for providing a sealed chamber (40) adjacent to a workpiece (28) to counteract the influence of gravity on the workpiece (28) includes a chamber housing (244), and a seal assembly (33) that expands and/or contracts to better seal against the workpiece (28). Further, the chamber assembly (26) can include one or more transducer assemblies (34) that expand or contract to quickly respond to leaks or injections of fluid in chamber assembly (26) to maintain a constant and stable chamber pressure in the chamber assembly (26). Moreover, the chamber assembly (26) can utilize a pressure source (35) that directs a lager amount of fluid (374) through a fluid passageway (368) to accurately maintain the pressure within the chamber assembly (26).

An image stabilizer includes a guide device which guides an image-stabilizing optical element in a guide direction orthogonal to an optical axis and an image shake counteracting driving device which moves the image-stabilizing optical element so as to counteract image shake, including a first moving element moved by a drive source; a second moving element movable relative to the first moving element, and applies a moving force to a holder holding the image-stabilizing optical element when the second moving element is moved by the first moving element; and a moving-element control mechanism which resiliently connects the first and second moving elements to each other to allow the first and second moving elements to selectively move integrally and relative to each other in accordance with a magnitude of a resistance to a movement between the drive source and the holder.

Vacuum easel for releasably holding material. The vacuum easel includes a panel having a first sheet and a second sheet with a plurality of walls disposed between the first and second sheets. The walls define a series of progressively larger air pathways between the first and second sheets. A plurality of openings are formed in the first sheet to allow communication of air between the exterior of the first sheet and the respective air pathways. At least a subset of the openings are associated with each of the air pathways. A zone selector is operable to selectively communicate a source of vacuum with at least one of the air pathways to draw air from the exterior of the vacuum easel through the openings associated with the selected air pathway.

An exposed and developed photographic film is moved through a copying machine between a fixedly mounted lower guide member and an upper guide member which is movable up and down away from and toward the lower guide member. The confronting surfaces of the guide members have raised portions which surround registering windows of the guide members and engage a film all the way around a film frame which is aligned with the windows when the film is brought to a halt. Once the imaging of the frame which is aligned with the windows is completed, several springs lift the upper guide member, and ports in the raised portions of the confronting surfaces discharge jets of compressed air which cause the film to levitate between the two guide members during advancement of the next film frame to a position of alignment with the windows. This reduces the likelihood of scratching of and/or other damage to the film during transport. The ports can receive compressed air without interruption or only while the upper guide member is lifted above and away from the lower guide member.

A document handler 20 for presenting documents to the platen 23 of a copier 10 for copying with a vacuum belt platen transport system 32 having document transporting belts 35 movable under a substantially planar vacuum plenum backing and imaging background surface 33a overlying the platen, and a vacuum system 33 for applying a partial vacuum to a document sheet being transported by the movable belts over the platen; with a clamping and unclamping system for moving the vacuum plenum backing and imaging background surface 33a against the platen 23 to flatten the belts 35 and a document thereon against the platen for copying. During unclamping the surface 33a slightly fits away from the platen, while supplying the partial vacuum to lift a document away from the platen retained on the belts, by first lifting a first side of the surface 33a up away from the platen substantially before the opposite side, and then subsequently lifting the opposite side, to generate a controlled air flow for assisting in retaining the documents to the belts, and moving the belts when the surface is lifted away from the platen. During clamping the first side of the surface 33a moves towards the platen beginning slightly before the opposite side to generate a controlled air flow expulsion of air.

In an automatic document handling system for a copier, with a system for feeding and registering document sheets, including a platen transport system, wherein the platen transport system includes a document belt system and a vacuum system for retaining documents against the document belt, there is provided common document input and path systems for feeding either conventional document sheets or computer form or other web (CF) documents, the document belt system relatively low friction belt material, the vacuum system automatically maintaining a first vacuum level high enough to retain the conventional document sheets against the document belt system with sufficient force to resist slippage and function as their primary platen transport system, and a vacuum reduction system for automatically reducing the vacuum to a substantially lower level for CF documents which provides for slippage of CF documents relative to the document belt system, and a separate deskewing and driving system for the CF documents in cooperation with the platen transport system, for deskewing the CF web upstream of the platen and pulling through the platen transport system from downstream thereof, to provide a dual mode system in which the platen transport system provides for low frictional relative movement and an imaging background surface for CF documents, but is not their primary transport. There is a system for automatically sensing the acquisition of CF documents and in response automatically reducing the vacuum level and disengaging additional roller drive systems in the path which normally engage conventionally document sheets.

A stencil exposure apparatus that includes a frame with central translucent stencil mounting surface. A plurality of generally flat, resilient, compressible seal elements extend between opposite sides of the translucent surface and are movably mounted on the frame to accommodate the stencil exposure apparatus to a variety of stencil dimensions. A stencil chase mounting bar is movably mounted on the forward face of the frame, is connected to a support bar on the rear face of the frame, and which includes a mechanism for maintaining the orientation of the bar relative to the frame while the mounting bar is being moved. Mounting blocks are slidably mounted on the mounting bar and include a clamping mechanism for rapid lateral adjustment of the blocks.

The present invention relates to an original holding plate hinging mechanism for a copying machine, a printing machine or the like. When a thick solid original, such as a book, needs to be covered with an original holding plate, the pivotal point of the original holding plate is raised so that the original holding plate is placed practically horizontally on the thick solid original when closed. The original holding plate hinging mechanism comprises a supporting member attached rotatably to a member of the copying machine, an original holding plate joined at the rear end thereof to the free end of the supporting member so as to turn relatively to the supporting member, and a resilient means interlocked with both a member of the copying machine and the supporting member to control the torque for turning the supporting member.According to the present invention, the mechanism further includes a control means interlocked with both the supporting member and the original holding plate to control the turning motion of the original holding plate relative to the supporting member.
