A sheet deceleration apparatus includes a pair of rotatable rollers, being rotatable about first and second axes, the rollers positioned on opposite sides of the travel path. At least one of the rollers is moveable relative to the other to nip the sheet between the rollers to reduce the travel speed of the sheet. A vacuum conveyor is further provided along the travel path subsequent the pair of rollers to control delivery of the sheet to a stacking hopper. A third rotatable roller, or similar apparatus, may be included in some embodiments, for pushing the sheet of material away from the vacuum conveyor at the appropriate time.

A device for pulling in flat-stock pieces and precisely-aligned transporting of the flat-stock pieces at a work station of a machine for processing the flat-stock pieces has a gripper apparatus that grabs a forward edge of a piece of flat stock and accelerates the flat-stock piece, and a sheet pick-up roller that picks up the accelerated piece of flat stock from the gripper apparatus, whereby the sheet pick-up roller has a roller gripper effective at a circumference thereof for grabbing the accelerated piece of flat stock. The roller gripper can move between a closed position in which the piece of flat stock is held fast and an open position in which the piece of flat stock is released. Suction holes operable to be charged with intake air are disposed in a part of a circumference of the sheet pick-up roller following in a direction of rotation behind the roller gripper.

A non-gouging sheet stripper assembly is disclosed for stripping copy sheets from a surface of a moving fusing member. The non-gouging sheet stripper assembly includes (a) at least one baffle forming part of a sheet path; (b) a finger shaft having a first end attached to the at least one baffle and a second distal end for forming a sheet directing first angle with the surface of the moving fusing member; and (c) a finger tip located at the second distal end of the finger shaft and having a contour for forming a sheet stripping second angle, that is different from the sheet directing first angle with the surface of the moving fusing member.

A currency note storage device (10) for an ATM (50) comprises an endless rubber belt (12) carrying a multiplicity of outwardly-projecting flaps (22), the edges of the flaps attached to the belt being contiguous; the belt (12) runs around a pair of rollers (14,16) of such diameter that as the belt runs over them, the outer edges of the flaps are spread apart to form slots; the belt also runs around a pair of guides (18,20) of such diameter that as the belt runs over them the flaps are barely spaced apart. The number of slots is known, and therefore each slot is addressable; the processor (62) of the ATM (50) records the value of the currency note in a slot, and controls a stepper motor (66) to drive the belt (12) so that a required bank note (34) is positioned adjacent a pick device (38). The device (10) can also be used to deposit currency notes in an ATM.
摘要:
A fuser stripper apparatus for use in a machine which imparts an image to paper being fed therethrough. The apparatus has: a fuser roller rotatably fixed in the machine and having a surface treated with a coating for effecting the impartation of the image to the paper, the fuser roller has at least one slot formed in its surface; an idler roller rotatably fixed in the machine which has a surface in substantial contact with the surface of the fuser roller thereby creating a nip for passage of the paper therein when either of the fuser or idler rollers are rotated; a motor for rotating one of the fuser or nip rollers; and a wire member disposed in each of the at least one slot formed on the surface of the fuser roller, the wire member has first and second ends fixed to the machine such that the paper is prevented from wrapping around the fuser roller by the wire member. In preferred embodiments, the machine is a printer, photocopier, or facsimile machine and the fuser stripper apparatus is contained in a removable component of the machine.
摘要:
A development process and a fixing process are carried out on a front side of a recording paper. The paper recorded on the first side is transported toward a returning transportation device. The development process and the fixing process are then carried out on a back side of the paper. A nozzle for blowing out an air flow, an inverter roll for inverting the paper and the returning transportation device are arranged between the fixing station and a reversal station. The paper is deformed by the local cooling due to the air for peeling by the nozzle, the inverter roll and the returning transportation device. The portions (working regions) which receive the local cooling are arranged such that at most two of the working regions occur at any point of the recording medium paper. The inferiority of the local images in the defects in transfer and the local lowering degree in the density of the images are decreased.

A symmetrically flexible separator device is placed immediately after and removed, by a pair of pads, from the nip between the fuser roller and the pressure roller in order to intercept the leading edge of an image-bearing receiver and thus reduce the risk that the latter would remain stuck to the surface of either the fuser roller or the pressure roller.

This invention relates to a separating pawl installed in a copying machine wherein at least an edge of the separating pawl is composed of an amorphous carbon layer; the edge of the separating pawl being in contact with a surface of a photosensitive member on a surface of a fixing roller to separate a sheet like member.

The present invention relates to a paper releasing guide-claw for a copying machine and a method for producing the same including molding a material containing from about 50-90% by weight of a polyimide consisting essentially of recurring units of the formula: ##STR1## from about 5 to about 40% by weight of a fibrous reinforcing material, and from about 5 to about 30% by weight of a solid lubricant, wherein the sum of the content of the fibrous reinforcing material and the solid lubricant is from about 10 to about 50% by weight, heat treating the molded guide-claw at a temperature of from about 250.degree. C. to about 340.degree. C. for a time sufficient to increase the density of the polyimide component by 1.5%.
摘要:
An image forming apparatus wherein an image formed on an image bearing member is transferred onto a transfer material carried on the transfer material carrying member. The transfer material carrying member is capable of electrostatically attracting a plurality of transfer materials, so that good quality images can be provided at a high overall image formation speed with a simple structure, because the possible deterioration of the quality of the image attributable to the difference between the effect of presence of the transfer material on the transfer material carrying member and the absence thereof on the transfer material carrying member can be minimized.
