Description
x-y-koordinatlisare Foreliggande uppfinning avser en x-y-koordinatlasare enligt ingressen till det oberoende kravet. The present invention relates to an x-y coordinate laser according to the preamble of the independent claim.
Sarskilt avser den en sadan en x-y-koordinatlasare avsedd att anvandas pa ett satt som motsvarar en datormus eller liknande. In particular, it refers to such an x-y coordinate laser intended to be used in a manner corresponding to a computer mouse or the like.
Uppfinningens bakgrund x-y-koordinatlasare som anvands pa ett satt som motsvarar en datormus, men omfattar ett rullande band är kanda genom exempelvis EP0130649. Bandet är utformat av ett tyg- eller gummiliknande material. Lamnas bandet i ett visst ldge under lang tid, tenderar bandet att strava att bibehalla den form det lamnats i, det viii saga det finns ett inneboende formminne i materialet. I ett extremt fall kan, om bandet forskjuts frail detta lage och darefter slapps, bandet spontant aterga den den ursprungliga positionen. Denna effekt kan minskas genom att anvanda ett tunnare band, men sadana tenderar att slitas snabbt och ha en fj ddrande verkan, vilket ger x-ykoordinatlasaren dalig precision och kort livstid. Background of the Invention The x-y coordinate laser used in a manner similar to a computer mouse but comprising a scroll belt is known by, for example, EP0130649. The band is formed of a fabric or rubber-like material. If the tape is left in a certain length for a long time, the tape tends to strive to maintain the shape in which it was left, which means that there is an inherent shape memory in the material. In an extreme case, if the belt is displaced from this position and then released, the belt can spontaneously regain its original position. This effect can be reduced by using a thinner band, but these tend to wear quickly and have a resilient effect, giving the x-y coordinate laser poor precision and short life.
Ett andamal med uppfinningen är darfor att tillhandahalla en x-y-koordinatldsare som inte har denna inneboende formminne, men har lang livstid och liten fjaderverkan. An object of the invention is therefore to provide an x-y coordinate sensor which does not have this inherent shape memory, but has a long life and small spring action.
Dessa och andra andamal uppnas genom en x-y-koordinatlasare enligt de kannetecknande delarna av det oberoende kravet. These and other purposes are achieved by an x-y coordinate laser according to the features of the independent claim.
Sammanfattning av uppfinningen Uppfinningen avser en x-y-koordinatldsare utformad att utlasa rorelsen i tva riktningar pa en styryta, dar styrytan omfattar ett slutet band som kan rotera i en forsta riktning och är anordnad att kunna riira sig i en andra riktning. Bandet utgors pa fordelaktigt sat av en kedjeliknande anordning vilken inte har tendens att strdva at flagon sarskild foredragen position. Summary of the invention The invention relates to an x-y coordinate sensor designed to read the motion in two directions on a guide surface, where the guide surface comprises a closed band which can rotate in a first direction and is arranged to be able to move in a second direction. The belt is advantageously formed by a chain-like device which does not tend to stray to the particular preferred position of the flag.
I en fordelaktig utfOringsform utgors den kedjeliknande anordningen 1 av intill varandra anordnade lankstavar 2, dar vane lankstav är vridbart ansluten till tva intilliggande lankstavar sa att lankstavarna bildar en sluten slinga. Typiskt är vane lankstav 2 vridbart ansluten till tva 1 intilliggande ldnkstavar med lankar 3. Den kedjeliknande anordningen kan vara lindad kring en sldde 6 som är anordnat pa en skena 7 sa att den kan rora sig langs den. In an advantageous embodiment, the chain-like device 1 consists of longitudinal longitudinal rods 2, where the usual longitudinal rod is rotatably connected to two adjacent longitudinal rods so that the longitudinal rods form a closed loop. Typically, the habit long rod 2 is rotatably connected to two adjacent link rods with lengths 3. The chain-like device may be wound around a screen 6 which is arranged on a rail 7 so that it can move along it.
Uppfinningen avser ddrtill en sadan x-y-koordinatldsare som omfattar en optisk rorelsesensor som detekterar bandets 1 rorelse, dar den optiska rorelsesensorn vid bruk pa fordelaktigt sat är huvudsakligen riktad nedat.

Kort beskrivning av figurerna Fig. 1 visar en kedja enligt uppfinningen separat Fig. 2 visar tva kedjeldnkstavar separat Fig. 3 visar kedjan pa en skena sett snett uppifran Fig. 4 visar i partiellt tvdrsnitt kedjan pa en skena sett snett nedifran Fig. 5 visar ett tvarsnitt genom kedjan monterad i ett holje Fig. 6 visar i partiellt tvarsnitt kedjan monterad i holjet sedd rakt uppifran Fig. 7 visar kedjan monterad i holjet sedd rakt uppifran Beskrivning av en foredragen utfciringsform Uppfinningen avser en x-y-koordinatldsare, alltsa en anordning som likt en datormus kan detekterar en anvandares hand- eller fingerrOrelser i ett plan och generera styrsignaler till en dator som omfattar information om atminstone denna rOrelse i ett plan, typiskt separerade som information om rorelse i x-y-koordinatlasarens x-riktning och rorelse i x-y-koordinatldsarens y- riktning. x-y-koordinatlasaren bygger pa anvandande av en kedjeliknande detalj som beskrivs i detalj nedan. Brief description of the figures Fig. 1 shows a chain according to the invention separately Fig. 2 shows two chain guide rods separately Fig. 3 shows the chain on a rail seen obliquely from above Fig. 4 shows in partial cross-section the chain on a rail seen obliquely from below Fig. 5 shows a cross section through the chain mounted in a housing Fig. 6 shows in partial cross section the chain mounted in the housing seen straight from above Fig. 7 shows the chain mounted in the housing seen straight from above Description of a preferred embodiment The invention relates to an xy coordinate conductor, i.e. a device like computer mouse can detect a user's hand or finger movements in a plane and generate control signals to a computer that include information about at least this movement in a plane, typically separated as information about movement in the xy coordinate laser x direction and movement in the xy coordinate reader y direction. The x-y coordinate laser is based on the use of a chain-like detail described in detail below.
Fig. 1 visar en kedja enligt uppfinningen separerad fran ovriga delar. Kedjan omfattar en serie ldnkstavar 2 parvis anslutna till de omedelbart intilliggande lankstavarna med ldnkar 3. Varje lankstav är forsedd med tre urtag pa sin ena sida och tre urtag pa sin andra sida. Urtagen pa ena 2 sida är forskjutna relativt urtagen pa den andra sidan ett stycke i respektive lankstavs langsriktning. Kedjan i sin helhet kommer pa sá sat att vara hoplankad med sex rader lankar, som loper parallellt i tre par rader. Fig. 1 shows a chain according to the invention separated from other parts. The chain comprises a series of connecting rods 2 in pairs connected to the immediately adjacent longitudinal rods with connecting rods 3. Each longitudinal rod is provided with three recesses on its one side and three recesses on its other side. The recesses on one side are offset relative to the recesses on the other side a bit in the longitudinal direction of each long bar. The chain as a whole will in this way be linked together by six rows of links, which run parallel in three pairs of rows.
Kedjan är i figuren formad som en sluten slinga med plana Over- och undersidor som toper parallellt med varandra. Kedjans Over- och undersidor Riper ihop med varandra vid tva krokta andpartier. Kedjan har fordelen att den är helt eftergivligt for bOjning lank mot lank och kan anta en form i ett tvarsnitt genom kedjan som är formad pa vilket onskat salt som heist och den tenderar inte att fastna i eller strava efter nagon sarskild form, sA. som ett motsvarande band av ett homogent material skulle Ora. Den form kedjan har i figuren antar den pa grund av att den är lindad kring en slade som beskrivs i stone detalj nedan. Utan sladen skulle kedjan av sin egen vikt naturligt falla ihop till en mer plan form. The chain is in the figure shaped like a closed loop with flat upper and lower sides that top parallel to each other. Upper and lower sides of the chain Scratches together at two crooked duck parts. The chain has the advantage that it is completely resilient for bending long to long and can take a shape in a cross section through the chain which is formed on any desired salt and it does not tend to get stuck in or strive for any particular shape, so. as a corresponding band of a homogeneous material would Ora. The shape of the chain in the figure assumes it because it is wrapped around a sledge which is described in stone detail below. Without the sled, the chain of its own weight would naturally collapse into a more planar shape.
Fig. 2 visar tva kedjelankar 2 separat fran resten av kedjan och illustrerar hur kedjan är sammanlankad. Sammanlankningen sker med lankar 3 som skjuts ned i de oppningar som bildas av matchande urtag pa tva intill varandra liggande lankstavar. Varje lank kan i sin langsriktning, alltsa samma riktning som lankstavama, i sift inre motta tva lankpinnar 4. Lankpinnarna leper genom respektive lank och sticker ut fran lanken At bada hall. De utstaende partiema av lankpinnarna skjuter in i mottagningsoppningar i lankstavarna och lankstavarna kan latt rotera kring de bada lankpinnarna. Lankpinnarna är vid bruk fasta i lage i lankarnas inre med ett snappe 5. Fig. 2 shows two chain anchors 2 separately from the rest of the chain and illustrates how the chain is linked together. The interconnection takes place with lengths 3 which are pushed down into the openings formed by matching recesses on two adjacent longitudinal bars. Each lank can in its longitudinal direction, i.e. the same direction as the lank rods, in sift inner receive two lank sticks 4. The lank sticks lep through each lank and protrude from the lank At bathing hall. The protruding portions of the longitudinal pins project into receiving openings in the longitudinal rods and the longitudinal rods can easily rotate about the two longitudinal rods. In use, the anchor pins are fixed in a layer in the interior of the anchors with a snap 5.
Fig. 3 visar kedjan 1 monterad pa en slade 6 som i sin tur glider pa en skena 7 sett snett uppifran. Kedjan kan latt fas att glida runt sladen genom att den skjuts uppifran i en riktning som är vinkelrat mot lankstavarnas langsriktning. Kedjan pa sin slade kan dartill Mit las att glida langs skenan genom att pa kedjans overyta applicera en kraft i riktning parallellt med lankstavarnas langsriktning. PA sa sat kan en anvandare rora kedjans overyta At vilket hall som heist i ett plan och utlasning av denna rorelse kan sedan anvandas for att genereras styrsignaler till en dator pa ett satt som motsvarar de fran en datormus eller liknande. Fig. 3 shows the chain 1 mounted on a slide 6 which in turn slides on a rail 7 seen obliquely from above. The chain can be easily slid around the sled by pushing it from above in a direction perpendicular to the longitudinal direction of the longitudinal rods. The chain on its sled can also be read to slide along the rail by applying a force to the upper surface of the chain in a direction parallel to the longitudinal direction of the long bars. In this way, a user can move the surface of the chain at which hall is lifted in a plane and readout of this movement can then be used to generate control signals to a computer in a manner corresponding to those from a computer mouse or the like.
Sladen dr den ande som vetter mot betraktaren forsedd med ett utsthende element 8 som samverkar med en andlagessensor och nar andlagessensom detekterar det utstaende elementet 8, genereras en signal som indikerar att sladen natt ena andlaget. PA motsatt sida av sladen finns anordnat en andra andlagessensor som pa motsvarande satt detekterar att sladen natt det andra 3 andlaget. The spirit where the spirit facing the viewer is provided with a protruding element 8 which cooperates with a spirit sensor and when the spirit sensor detects the protruding element 8, a signal is generated which indicates that the slave is at night one spirit. On the opposite side of the sled there is arranged a second breath sensor which in a corresponding manner detects that the sled night the other 3 breath.
Fig. 4 visar i partiellt tvarsnitt kedjan pa sldden som loper pa skenan sett snett nedifran. Ett parti motsvarande tre intill varande liggande lankstavar pa undersidan av kedjan har eliminerats ur figuren sá att skenans 7 undersida blottas. Pa skenans undersida är en kamera 10 anordnad som detekterar kedjans rarelse och genererar styrinformation till en dator eller liknande. Eftersom kamerans apertur är riktad nedat minimeras risken att kameran ackumuleras smuts och kameran kommer att fungera problemfritt under lang tid utan nagot behov av rengoring. Fig. 4 shows in partial cross-section the chain on the sling which runs on the rail seen obliquely from below. A portion corresponding to three adjacent longitudinal rods on the underside of the chain has been eliminated from the figure so that the underside of the rail 7 is exposed. On the underside of the rail, a camera 10 is arranged which detects the movement of the chain and generates control information for a computer or the like. Since the aperture of the camera is directed downwards, the risk of the camera accumulating dirt is minimized and the camera will function smoothly for a long time without any need for cleaning.
Fig. 5 visar ett tvarsnitt ldngs ett plan som är vinkelratt mot lankstavarnas ldngsriktning och illustrerar kedjan 1 monterad i ett holje 12. Figuren illustrerar hur skenan 7 är forsedd med ldngsgaende forsdnkta spar i vilka loprullar 11 är anordnade. Med hja.lp av loprullarna kan kedjan pa sldden 6 latt och med mycket lag friktion lopa langs skenan 7. Fig. 5 shows a cross section along a plane which is perpendicular to the longitudinal direction of the longitudinal rods and illustrates the chain 1 mounted in a housing 12. The figure illustrates how the rail 7 is provided with longitudinally recessed grooves in which running rollers 11 are arranged. With the help of the running rollers, the chain on the sling 6 can run along the rail 7 easily and with very low friction.
Fig. 6 visar i partiellt tvdrsnitt kedjan monterad i holjet sedd rakt uppifran. Tvdrsnittet är valt sã att kedjan och skenan i sin helhet blottas, medan skenan normalt inte blottas alls och bara ett parti av kedjan blottas mot anvandaren. Fran kedjans nedre sida stracker sig tva armar och pa dessa armars yttre andor är tva trycksensorer 12a-b anordnade som kan anvandas for att lata brukaren generera musklicksignaler. Fig. 6 shows in partial cross-section the chain mounted in the housing seen straight from above. The cross-section is chosen so that the chain and the rail in its entirety are exposed, while the rail is not normally exposed at all and only a part of the chain is exposed to the user. Extending from the lower side of the chain are two arms and on the outer ends of these arms two pressure sensors 12a-b are arranged which can be used to allow the user to generate mouse click signals.
Fig. 7 visar kedjan monterad i holjet sedd rakt uppifran, alltsa en vy over hur anvandaren normalt ser x-y-koordinatldsaren. Av kedjan 1 blottas bara ett parti och kedjan är sa anordnad att dess langsta mojliga rorelse pa skenan at bade Niger och vdnster aldrig blottar kedjans ytterkant, utan anvandaren ser bara en obruten kedjeyta. Genom att med ett finger rora kedjeytan kan brukaren pa sa sat styra exempelvis en mark& pa en dator. Fig. 7 shows the chain mounted in the housing seen straight from above, i.e. a view of how the user normally sees the x-y coordinate array. Of the chain 1, only one part is exposed and the chain is so arranged that its longest possible movement on the rail at both Niger and left never exposes the outer edge of the chain, but the user sees only an unbroken chain surface. By touching the chain surface with one finger, the user can thus control, for example, a ground & on a computer.
Uppfinningen beskriver bara en kedjetyp, men uppenbart kan kedjan utformas pa manga olika sat och med ett fritt valt antal lankstavar. Fordelningen av lankarria som sammanldnkar ldnkstavarna behover naturligtvis inte vara ldngs sex rader, utan kan se ut pa annat salt. 4 The invention describes only one type of chain, but obviously the chain can be designed in many different ways and with a freely chosen number of long bars. Of course, the distribution of lankarria that unite the rods does not have to be six rows long, but can look like other salt. 4
