Abstract

The utility model relates to a copy pen which can copy normal paper with a proper function. The copying way is that in the writing process, the copy pen tightly pricks a plurality of pieces of paper to form small holes and leaks ink, so that the paper leaves behind the handwriting formed by the ink holes. The writing head is composed of a tubular fixed stylus and an active amphiox stylus. After batteries are switched on by a power switch, a slide block on a miniature motor axis pushes a talus in the tail end of the cartridge with the proportion of the spring to make the active stylus thrust a nib continuously and rapidly. The copy pen contains ink. The utility model has the advantages of convenient regulation of pages, and clear copy handwriting without erasable performance and counterfeit performance.

Description

Duplicating pen

This is novel to be the writing appliance that is used to make carbon copies.

Existing manifolding apparatus and manifolding method are to fold into carbon paper or use the special paper with coating between the page of desire manifolding, draw the pressure of writing with rigid nib at last page of paper and act on the coating on carbon paper or the page and stay person's handwriting on nextpage paper.

Still useless Duplicating pen and do not depend on carbon paper between page and the coating between page or leaf can be made carbon copies common several pages.

This novel purpose is to exempt stack carbon paper or adopt loaded down with trivial details and limitation that special paper makes carbon copies and the pollution of copying paper paint.Improve manifolding efficient and manifolding quality.Manifolding is convenient, writing is clear and long preservation but make, and is convenient to use in vast scope.

The method that reaches the purpose of putting forward is oozed with ink to the aperture of being worn when to be logarithm page or leaf writing paper by stroke undertaken puncturing aperture closely continuously, makes upper and lower paper stay the stroke of being made up of these apertures, and this method can reach the purpose of manifolding.

Duplicating pen possesses the desired repertoire of above-mentioned manifolding method.Duplicating pen also is equipped with spring, micromotor, power supply and power switch in a shell except that having a shell, the pen cap, pencil, storage inking chamber, pen core.This pencil is made up of with the fixing nib that is enclosed within its outer tubulose the movable nib of prong shape.Movable nib connects with pen core, can push periodic thrust of micromotor and spring counter and axially make back and forth movement along pen.Connect the power supply micromotor when power switch and start working, movable nib is just stretched out the withdrawal nib continuously apace.Fixing nib and movable nib are simultaneously along paper writing during manifolding, fixing nib stays the movable nib of the stroke of writing as pen and then pierces through simultaneously upper and lower page or leaf paper continuously fast on last page or leaf paper, make nextpage paper stay the stroke of being made up of the compact arranged many apertures that are impregnated with ink.Fixedly nib also plays support to Duplicating pen and to the effect of the written ink supply water of activity in when manifolding.

A micromotor and a shell concentric are installed rationally to utilize the space, so the horizontal revolving force of micromotor is become the thrust of axial cyclic.On its output shaft, establish eccentric slide block.Pen core with and between a shell concentric is placed in one, the end face of the terminal garden of pen core cylindricality slightly inclines into the inclined-plane and matches with slide block, when slide block rotation compressing inclined-plane protrudes the position, just on pen core, produce axial thrust, just produce stretching motion one time because the repulsion of spring whenever circles micromotor again.

Control activity nib is thrust the number of pages that the degree of depth in the paper can be controlled manifolding.

A shell of Duplicating pen is made of by thread connection body and shell head.The front portion of shell head links to each other with fixing nib, and it is built-in with the spring that makes the pen core withdrawal.Screw out or the first extreme length that just can make movable nib stretch out fixing nib of precession shell adjusted, thereby reach the purpose of selecting the number of pages of making carbon copies.Be the loose shift that prevents to connect, between shell head and body, be provided with the spring washer of location; Be with elastic rubber tube between the end of shell head and pen core, make and form the storage inking chamber of isolating with body in the shell head, make back and forth movement for adapting to pen core, elastic rubber tube axially is being wrinkle shape; When the promotion pen core is made back and forth movement, elastic rubber tube also is subjected to periodic contractility, for making the ink in the storage inking chamber under this pressure effect, obtain buffering, on the wall of shell head, open open to atmosphere pore outside several and with the capillary of pore UNICOM, ink is excessive and adsorbed by capillary by pore when storage inking chamber pressurized, and excessive ink refluxes by these pore pipes again when the storage inking chamber is subjected to negative pressure.But these hole pipes are the suction hole of double as storage ink also; Be provided with small cell in the body and make power supply, on body, also be provided with supply socket and use for external power supply for adapting to different needs.

The volume of Duplicating pen, writing speed and storage are more or less the same with the function and the common pen of ink, will install power supply additional only, and then the pen footpath is slightly thick than No. 5 batteries to intend using No. 5 batteries to make power supply.So carry with easy to use, and unlike carrying and use overrides and a lot of inconveniences arranged the paper.The supply voltage of Duplicating pen is 1.5 volts of levels, the power of the suitable trumpeter's torch small electric bulb of consumed power, and long-time use can patch external power.The number of pages of the paper that Duplicating pen is once made carbon copies can reach five pages, and writing is clear, and the word of nextpage is just unintelligible for a long time in number of pages if use the carbon paper manifolding; The number of pages of Duplicating pen manifolding can or screw out shell head and selection easily by precession within the specific limits; If excessively screw out shell head movable nib is not exposed when fixing nib fully, Duplicating pen can be write (need not connect and use power supply this moment) as conventional pen.

What Duplicating pen was used is perforation ink bleed method, so writing gos deep into can not erasing in the paper.Duplicating pen use ink write not can be as use carbon paper writing band oiliness thing, be warm or time length can melt unintelligible, so its writing helps long preservation.Using the font of Duplicating pen also to have can not imitation property, still its stroke of writing is not clear for this, and, the density degree of the aperture that forms stroke on the nextpage paper is also changed thereupon with the movable nib of fixed frequency perforation because the speed of everyone writing stroke changes with self custom.Can further identify each one font with the variation of stroke and this density.So the font of using Duplicating pen to write almost can not be copied.Very suitable finance and important document aspect are used.

The Duplicating pen of being advised has a shell and the pen cap.Shell is made of body 1 and shell head 2.The tubulose pen core 7 that has a style of one's own is housed in the middle of the shell, and the root of the movable nib 4 of the prong shape in the middle of its anterior tube wall grips, its afterbody connect one and accompany garden, the inclined-plane plate of certain angle with shaft section.The structure of cap sample is to consider on the plate of garden, inclined-plane to deposit some lubricating oil around the plate of garden, inclined-plane.The anti-spring 9 that pushes away pen core 7 is housed in the shell head 2.Storage ink capsule 8 tightly is enclosed within the end of shell head 2 and the afterbody of pen core 7 respectively, makes and has formed the storage inking chamber in the shell head 2.It axially is being wrinkle shape, is convenient to pen core 7 and makes back and forth movement vertically.The front end of shell head 2 is the fork shape, has formed inner and outer wall.Inwall connects fixing nib 3, has in wall that open to atmosphere pore 6 and 17 communicates with spiral capillary outside wall outside two.Its effect has 2 points; The one, when making back and forth movement, pen core 7 make the ink in the storage inking chamber obtain buffering.The 2nd, when pressing storage ink capsule because the interaction energy of pore 6 and 17 is drained the air in the storage inking chamber and inspiration ink.Outer wall plays protection covering effect to inwall.Body is equipped with micromotor 5, battery 15 and rotary power switch 16.The output shaft of micromotor has eccentric outstanding slide block 10, movable nib 4 protruding nibs during the protrusion position of garden, the inclined-plane plate of head slider 10 rotation compressing pen cores 7 partially under the drive of micromotor, when eccentric shoe 10 goes to the recessed position of plate, garden, inclined-plane, answer counter the pushing away of spring 9 to make movable nib 4 withdrawal nibs.It is 1.5 volts of levels that micromotor intends using axial force-bearing type, electric pressure.Between body 1 and shell head 2, have the serration of spring washer 11 and body 1 and first 2 interfaces of shell to match to close and tighten up and positioning action, when excessive back-out shell head 2 makes movable nib 4 can not stretch out nib fully then Duplicating pen can be used as the ordinary steel pen and use.5 of 14 pairs of micromotors of elastic tape tighten up and damping effect, and elastic tape 13 is except that playing this effect, and its ring-like circle 12 that is embedded with metal or plastic material is made garden, the inclined-plane plate of the pen core 7 of back and forth movement with support.The afterbody of body 1 is made of the shell tail 21 of metallic conduction material, and the two all connects with the cap 19 of connecting in it with screw thread.Connecting cap 19 is the metallic conduction material with the outer ring that body 1 and shell tail 21 connect, be welded with the negative line of the power line 18 of micromotor 15, the base plate that connects cap 19 is that insulation board and outer ring connect with rivet, and the electrode line of positive contact source of welding current line 18 is made in the centre of insulation board with rivet stationary spring 20.The outer ring that connects cap has jack 22 external power of can pegging graft, and must take out internal cell 15 during the grafting external power, and shell tail 21 will be outwarded winding till connect jack on the cap outer ring and all expose.The outer core of the plug that desire is pegged graft is a negative pole and connects the conducting of cap outer ring, inner core for positive pole and on the top conducting of the spring leaf 20 of lifting up.But whiz shell tail 21 fetching batteries.Rotary power switch 16 comprises the rotating shaft 23, insulation spacer 26, insulating barrier 24, flexible metal movable contact 25 of shell 27, the metal material of plastic material and by two fixed contacts of forming with the rivet of shell tail conducting 28.Shaft head is double as GND contact in the shell tail, afterbody and movable contact conducting.Just drive movable contact 25 during shell 27 rotations and rotate, when movable contact 25 touched fixed contact, then power switch was in conducting state.Then power switch is in off-state when shell drives movable contact whiz fixed contact.
