An image-forming apparatus has a limitation pad 31c and a retard roller 34, which separately feed recording paper P on an elevation tray 31 in an MPT cover 30 by bringing the recording paper P against an outer peripheral surface 33a of the feeding roller 33. In this image-forming apparatus (paper feeder), when the feeding roller is stopped by passing recording paper to be separately fed to a pair of relay transport rollers, the elevation tray is lowered before stoppage of the feeding roller, the...

A paper cutter utilizing a lamp to illuminate a cutline scored into a transparent plastic surface located below directly below the paper to be cut. The silhouette of the cutline acts as the guideline for placement of the cutting blade of the paper cutter to thereby create the exact line of cut. A dual blade rotary cutter is also provided in a paper cutter with a toggle arrangement located on the carriage assembly which allows the user of the cutter to selectively engage one or the other of the b...

A paper magazine includes a shaft portion for rotatably supporting a paper roll inside a box-like frame, a paper transporting system configured for pinching a paper drawn out of the paper roll supported on the shaft portion by transport rollers and delivering this paper through an opening formed in the frame, and a transmission mechanism for effecting the delivery and rewinding of the paper through the opening by transmitting a forward drive force and a reverse drive force to the transport rolle...

Security paper adapted to resist fraudulent alteration of toner-printed information thereon and to make such alteration or attempts at alteration evident has a maximum Scott-Bond strength of 150 J m.sup.-2; a Bendtsen roughness of not more than about 150 ml min.sup.-1; and is size press or otherwise treated with a thermally-softenable polymer composition, for example acrylic polymer or copolymer, a polyvinyl acetate polymer, a vinyl acetate/ethylene copolymer, or a vinyl acetate/vinyl chloride/e...

A paper trap includes a trap chamber. An outlet of the trap chamber is preferably connected to an inlet of the exhaust bypass damper. An inlet of the trap chamber is coupled to dust capture hoods and an outlet of the bypass chamber is coupled to a dust collector. A perforated plate is disposed in the trap chamber to prevent scraps of paper from passing through the paper trap. The paper trap includes a normal operating position and a cleaning position. In a normal operating position, air from the...

The present invention relates to an improved paper clip which is suitable for holding documents of different thicknesses. The improved paper clip includes three elements, which are a first clipping piece, a second clipping piece and a support beam. The first clipping piece is formed with a sunken slot therethrough and is connected to a bottom side of the support beam. The second clipping piece has a bending curve part and is connected to a top side of the support beam. The bending curve part is ...

A paper cassette removably connectible to a body of an image forming apparatus. The paper cassette prevents a paper from being bent or crumpled. The paper cassette has a case wherein a paper is loaded, a finger rotatably installed at a side of the case to press a front corner of the paper, a spring installed at a lower side of the finger to flexibly support the finger to press the front corner of the paper, and a pressing plate installed at a lower side of the case to press the front corner of t...

In a paper discriminator having the line sensor and the point sensor, data to be obtained by the point sensor correspond to a common coordinate plane to data to be obtained by the line sensor. Thus, in partial data of the papers to be obtained by the point sensor also, a position for the entire surface of the papers of the part can be specified, and it is possible to compare data by the point sensor with reference data prepared in advance. Thus, discrimination precision of the papers is enhanced...

A conventional paper product used for printing or for fabrication into envelopes, file folders, forms and the like, is prepared by having antimicrobial agents added into the sizing during the manufacturing process. The antimicrobial agent provides protection to the paper from fungi, mildew and bacteria that could otherwise destroy the paper or be harmful to the user thereof.

The invention relates to coated printing paper which contains mechanical pulp and whose opacity is at least 89%, brightness at least 65% and surface roughness not more than 4.5 .mu.m. The printing paper contains mechanical pulp at least 90 weight-% of the total fiber content of the paper.
