Description
141796 i141796 i
Opfindelsen angår et afspilningsapparat, således som nærmere angivet i krav l's indledning.The invention relates to a playback apparatus, as further specified in the preamble of claim 1.
En videopladespiller af den i amerikansk patentskrift nr. 3.842.194 beskrevne art anvender almindelig-5 vis plader, der har en sportæthed af størrelsesordenen 150-300 sporvindinger pr. mm. En typisk videoplade af denne art har en sporafstand af størrelsesordenen 3,5 μ.A video recorder of the kind described in U.S. Pat. mm. A typical video disc of this kind has a track distance of the order of 3.5 μ.
Man kan ikke regne med at kunne anvende de forholdsvis smalle pladespors sarte vægge til at trække en stiftarm-10 enhed tværs over hele pladens indspillede overflade. I videopladespillere af den i ovennævnte patentskrift beskrevne art er det også for nøjagtig reproduktion af de forud indspillede signaler ønskeligt, at stiftelektroden opretholder en i hovedsagen konstant stilling i pla-15 desporet under afspilning. Apparatet omfatter derfor organer til sideværts bevægelse af den vogn, der bærer stiftarmenheden, i det rette tidsforhold til stiftens sideværts bevægelse som følge af spiralsporet for således til stadighed at holde stiftarmens længdeakse i hoved-20 sagen tangentielt til spiralsporet i punktet for indgreb mellem stiften og sporet under afspilning. Det amerikanske patentskrift nr. 3.870.835 viser en sådan drivmekanisme for sideværts bevægelse.One cannot expect to be able to use the delicate walls of the relatively narrow plate grooves to pull a pin-arm assembly across the entire recorded surface of the plate. In video recorders of the kind described in the above patent, it is also desirable for accurate reproduction of the pre-recorded signals that the pin electrode maintains a substantially constant position in the record track during playback. The apparatus therefore comprises means for lateral movement of the carriage carrying the stapler unit, in the proper time relationship to the lateral movement of the staple as a result of the spiral groove, so as to continuously hold the longitudinal axis of the staple arm substantially tangent to the spiral groove at the point of engagement between the staple and the track during playback. U.S. Patent No. 3,870,835 discloses such a drive mechanism for lateral movement.
Stiften behøver en vis sporingskraft for at sik-25 re korrekt sporing og lejring af stiften i pladesporet under afspilning.The pin needs some tracking power to ensure proper tracking and storage of the pin in the disc track during playback.
Stiftarmenheden har med henblik på tilvejebringelse af den ønskede sporingskraft en fjeder, der er forbundet mellem stiftarmen og vognen. Det har vist sig, at 30 en sådan fjeder bringer stiften til hurtigt at vende tilbage til pladesporet, når stiften kastes i vejret af en fejl i pladesporet.In order to provide the desired tracking force, the pin arm unit has a spring which is connected between the pin arm and the carriage. It has been found that such a spring causes the pin to quickly return to the plate groove when the pin is thrown by a failure of the plate groove.
På den anden side har anvendelsen af en fjeder, der strækker sig mellem stiftarmen og vognen, vist sig 35 utilfredsstillende, fordi den har tilbøjelighed til at bøje stiftarmen og frembringe uønskede svingninger i denne og skabe fejlsporing af stiften. Problemet er særlig 2On the other hand, the use of a spring extending between the pin arm and the carriage has been found unsatisfactory because it tends to bend the pin arm and produce undesirable oscillations therein and cause the pin to be mis-traced. The problem is particular 2
UT79SUT79S
akut, hvor stiftarmen er ekstremt sart og letvægtet, og hvor sporingshastigheden er forholdsvis høj.acute where the pin arm is extremely delicate and lightweight and where the tracking speed is relatively high.
Apparatet ifølge opfindelsen afhjælper dette problem ved hjælp af den i krav l's kendetegnende del an-5 givne udformning. Ved den således angivne direkte forbindelse mellem fjederen og stiften undgås belastningen på stiftarmen og dermed de nævnte risici for bøjning, uønskede svingninger og fejlsporing.The apparatus according to the invention alleviates this problem by means of the embodiment specified in claim 1. The direct connection between the spring and the pin thus indicated avoids the load on the pin arm and thus the mentioned risks of bending, unwanted oscillations and fault detection.
I princippet kan en hvilken som helst fjeder 10 anvendes, men det er særlig fordelagtigt som angivet i krav 2 at anvende en bladfjeder, idet denne er mindre tilbøjelig til at udføre indre svingninger end f.eks. en skrueviklet fjeder, og vil også kunne udformes med mindre masse end en sådan.In principle, any spring 10 can be used, but it is particularly advantageous, as stated in claim 2, to use a leaf spring, since it is less likely to perform internal vibrations than e.g. a helical spring, and may also be designed with less mass than such.
15 Ved den i krav 3 angivne udformning opnås at be lastningen på det eftergivende element bliver så lille som muligt. Herved undgås eventuelle ændringer i stiftarmens hvilestilling som følge af plastiske ændringer i det eftergivende element.In the embodiment of claim 3, the load on the resilient element is obtained as small as possible. This avoids any changes in the rest position of the pin arm due to plastic changes in the resilient element.
20 I de tilfælde, hvor apparatet er af den i krav 4's indledning angivne art, opnås ved den i dette kravs kendetegnende del angivne udformning, at selve fjederen udnyttes som elektrisk forbindelsesledning. Herved undgås behovet for en særlig ledning til dette formål.In the case where the apparatus is of the kind specified in the preamble of claim 4, the design as defined in the characterizing part of this claim provides that the spring itself is utilized as an electrical connection line. This avoids the need for a special cord for this purpose.
25 Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, på hvilken fig. 1 viser en videopladespiller ifølge opfindelsen med en fjederbelastet stiftarm, fig. 2 i perspektiv en patron, hvori den fjeder-30 belastede stiftarm i fig. 1 er anbragt, fig. 3 i perspektiv en stiftarmenhed, som den i fig. 1 og 2 viste fjederbelastede stift er fastgjort til, fig. 4 stiftarmenheden set fra siden således, at den fjederbelastede stiftarm ses, 35 fig* 5 stiftarmenheden i fig. 3 og 4 set forfra, og 3 141796 fig. 6 en del af en anden udførelsesform for den fjederbelastede stiftarm set fra siden.The invention will now be explained in more detail with reference to the drawing, in which 1 shows a video recorder according to the invention with a spring loaded pin arm; FIG. 2 is a perspective view of a cartridge in which the spring loaded pin of FIG. 1 is arranged; FIG. 3 is a perspective view of a pin arm assembly such as that of FIG. 1 and 2, spring-loaded pins are attached to FIG. 4 is a side view of the pin arm assembly so that the spring loaded pin arm is seen; FIG. 5 is the pin arm assembly of FIG. 3 and 4 are front view, and Figs. 6 is a side view of another embodiment of the spring loaded pin arm.
I fig. 1 betegner 10 en videopladespiller af den almindelige i amerikansk patentskrift nr. 3.842.194 viste 5 type. En videoplade 11 er drejeligt båret til afspilning på en pladetallerken 12, der er fastgjort til en motorplade 13 på pladespilleren. En vogn eller slæde 14 er monteret til sideværts bevægelse i forhold til motorpladen 13 i overensstemmelse med den sideværts bevægelse af 10 en stift 15, der glider i en spiralrille på pladen 13's overflade under afspilning.In FIG. 1 represents 10 a video record player of the general type shown in U.S. Patent No. 3,842,194. A video plate 11 is pivotally supported for playback on a plate plate 12 attached to a motor plate 13 on the turntable. A carriage or carriage 14 is mounted for lateral movement relative to the motor plate 13 in accordance with the lateral movement of 10 a pin 15 sliding in a spiral groove on the surface of the plate 13 during playback.
En stiftarmenhed 16 er indeholdt i en patron 17.A pin arm 16 is contained in a cartridge 17.
Patronen 17 optages i et rum 18, der er tilvejebragt i vognen 14. Fig. 2 viser patronen 17 i perspektiv.The cartridge 17 is accommodated in a space 18 provided in the carriage 14. FIG. 2 shows the cartridge 17 in perspective.
15 Som det ses i fig. 3 består stiftarmenheden 16 af en stiftarm 19, der er udformet med et aluminiumrør med f.eks. en ydre diameter på 0,6 mm og en tykkelse på 0,05 mm, og med en formstofstiftholder 20 fastlimet på den ene ende af stiftarmen og et eftergivende element 21 20 udformet ved den anden ende af stiftarmem. Det eftergivende element 21 udviser stor eftergivelighed for lavfrekvensbevægelse af stiftarmen 19, f.eks. på grund af pladeskævhed, ekscentricitet osv.. Stiftholderen 20 har 25 mindre eftergivelighed end det eftergivelige element 21, men har forholdsvis stor eftergivelighed for højfrekvensbevægelse af stiftarmen 19, f.eks. på grund af en kornet eller nopret overfladestruktur på pladen 11.15 As seen in FIG. 3, the pin arm 16 consists of a pin arm 19 formed with an aluminum tube with e.g. an outer diameter of 0.6 mm and a thickness of 0.05 mm, and with a resin pin 20 adhered to one end of the pin arm and a resilient member 21 20 formed at the other end of the pin arm. The resilient member 21 exhibits high resilience for low frequency movement of the pin arm 19, e.g. due to plate bias, eccentricity, etc. The pin holder 20 has less resilience than the resilient member 21, but has relatively high resilience for high frequency movement of the pin arm 19, e.g. due to a grainy or brittle surface structure of the plate 11.
Det eftergivende element 21 er i i hovedsagen 30 uspændt tilstand når det ligger på linie med stiftarmen 19. En forbindelsesplade 22 er fastlimet til det eftergivende element 21 således, at der etableres en vinkel på 94° imellem dem. Formstofstiftholderen 20 har en slids 23, i hvilken stiften 15 er limet på plads. Et lille 35 fremspring 24 er udformet øverst på formstofstiftholderen 20 til indgreb med en tilstødende væg i patronen for at frigøre stiften 15 fra en lukket eller blokeret rille.The resilient member 21 is generally unstressed when aligned with the pin arm 19. A connecting plate 22 is bonded to the resilient member 21 so that an angle of 94 ° is established between them. The plastic pin holder 20 has a slot 23 in which the pin 15 is glued in place. A small 35 projection 24 is formed at the top of the plastic pin holder 20 for engagement with an adjacent wall of the cartridge to release the pin 15 from a closed or blocked groove.
141796 4141796 4
Et sådant arrangement til frigørelse fra en lukket rille er vist i amerikansk patent nr. 4.049.280.Such an arrangement for release from a closed groove is shown in U.S. Patent No. 4,049,280.
Stiftarmenheden 16 er båret i patronen 17 ved hjælp af en elastisk membran 25 som vist i fig. 1 og 2.The stapler unit 16 is supported in the cartridge 17 by means of an elastic membrane 25 as shown in FIG. 1 and 2.
5 En U-formet fjeder 26 låser udløseligt stiftarmen 19 i en tilbagetrukket stilling i patronen 17 under dennes opbevaring og håndtering, dvs. medens patronen er uden for rummet 18. Den tilbagetrukne stilling giver en placering af stiften 15 trukket inden for patronen 17's grænse-10 flader borte fra en åbning i den nederste væg, som stiften kan rage ud igennem, f.eks. ved afspilning.5 A U-shaped spring 26 releasably locks the pin arm 19 in a retracted position in the cartridge 17 during its storage and handling, i.e. while the cartridge is outside the space 18. The retracted position provides a location of the pin 15 drawn within the boundary 10 faces of the cartridge 17 away from an opening in the lower wall through which the pin can protrude, e.g. when playing.
Et bæreelement 27 på et armstrækkerapparat 28 er i indgreb med forbindelsespladen 22, når patronen 17 er indeholdt i rummet 18. Arms trækkeren 28 er forskydeligt 15 monteret i rummet 18 til bevægelse mellem en tilbagetrukket stilling, når et låg 29 på vognen 14 er åbent, og en fremskudt stilling, når vognlåget er lukket, som reaktion på vognlågets bevægelse. Bæreelementet 27 trænger ind i patronen 17's indre gennem en åbning 30 i patronen for 20 at komme i indgreb med forbindelsespladen 22, når armstrækkeren 28 føres fremad. Et sådant arastrækkerapparat er vist i amerikansk patentskrift nr. 3.711.641.A support member 27 on an arm tensioning device 28 engages the connecting plate 22 when the cartridge 17 is contained in the space 18. The arm puller 28 is slidably mounted in the space 18 for movement between a retracted position when a lid 29 on the carriage 14 is open. and an advanced position when the carriage lid is closed, in response to the carriage lid movement. The support member 27 penetrates the interior of the cartridge 17 through an opening 30 of the cartridge 20 to engage the connecting plate 22 as the arm trigger 28 is advanced. Such an Arabian puller apparatus is disclosed in U.S. Patent No. 3,711,641.
En fjederafspændingsarm 31, der er fastgjort til vognlåget 29, træder ind i det indre af patronen 17 gen-25 nem en åbning 32 i denne for at afspænde låsefjederen 26 ved åbning af vognlåget, når der er indeholdt en patron i rummet 18.A spring-tensioning arm 31 attached to the carriage lid 29 enters the interior of the cartridge 17 through an opening 32 thereof to release the locking spring 26 upon opening the carriage lid when a cartridge is contained in the compartment 18.
Patronen 17 indeholder yderligere en bladfjeder 33 i fora af et bånd til at presse stiften 15 ind i plade-30 rillen til etablering af et stiftsporingstryk under afspilning som vist i fig. 1. Den ene ende af bladfjederen 33 er fastgjort til stiften 15 som vist i fig. 1, 3 og 4. Den anden ende af bladfjederen 33 er fastgjort til en flade 34 på en del af en kugle 35 som vist i fig.The cartridge 17 further includes a leaf spring 33 in the forums of a belt for pressing the pin 15 into the plate groove to establish a pin tracking pressure during playback as shown in FIG. 1. One end of the leaf spring 33 is attached to the pin 15 as shown in FIG. 1, 3 and 4. The other end of the leaf spring 33 is attached to a surface 34 of a portion of a ball 35 as shown in FIG.
35 1, 4 og 5. Kuglen 35 er friktionsbelastet i en fatning 36, der er tilvejebragt i patronen 17, således at den flade del rager ud fra soklen. Patronen 17 har en til- 5 U1796 gangsåbning 37 i forbindelse med fatningen 36 til indføring af et værktøj i et sekskantet hul 38 i kuglen 35 med henblik på indstilling af stiften. En sådan indstilling kan f.eks. tjene til at centrere stiftarmen 19 i pa-5 tronen 17 eller til at ændre stift/plade-sporingstryk-ket. Efter en sådan indstilling på fabrikken kan kuglen 35 limes fast.35 1, 4 and 5. The ball 35 is frictionally loaded in a socket 36 provided in the cartridge 17 so that the flat portion protrudes from the base. The cartridge 17 has an inlet opening 37 in connection with the socket 36 for inserting a tool into a hexagonal hole 38 in the ball 35 for adjusting the pin. Such a setting can e.g. serve to center the pin arm 19 in the cartridge 17 or to change the pin / plate tracking pressure. After such a setting at the factory, the ball 35 can be glued.
Stiftindstillingsapparatet er af den i amerikansk patent nr. 4.030.123 beskrevne art.The pin setting apparatus is of the kind described in US Patent No. 4,030,123.
10 Den anden ende af bladfjederen 33 er placeret så ledes, at stiftarmen 19 normalt ligger på linie med det eftergivende element 21. Som tidligere angivet er det eftergivende element 21 i i hovedsagen uspændt tilstand, når det ligger på linie med stiftarmen 19. Det er fordel-15 agtigt, at det eftergivende element 21 tilrettes med stiftarmen 19, fordi dette forhindrer dannelse af formspænding i det eftergivende element, der ellers kunne gribe forstyrrende ind i stiften 15's evne til at følge pladerillen.The other end of the leaf spring 33 is positioned so that the pin arm 19 is generally aligned with the resilient member 21. As previously stated, the resilient member 21 is substantially unstressed when aligned with the pin arm 19. It is advantageous 15 that the resilient element 21 is aligned with the pin arm 19 because this prevents the formation of mold stress in the resilient element which might otherwise interfere with the ability of the pin 15 to follow the plate groove.
20 Fig. 6 viser set fra siden en del af en anden ud førelsesform for det fjederbelastede stiftapparat, i hvilket bladfjederen 33 er bøjet i en retning modsat den i forbindelse med udførelsesformen i fig. 1-5 viste.FIG. 6 is a side view of a part of another embodiment of the spring loaded pin apparatus, in which the leaf spring 33 is bent in a direction opposite to that of the embodiment of FIG. 1-5.
Hvor stiften 15 indeholder en elektrode til detek-25 tering af signalvariationer i spiralrillen i pladen 11 under afspilning, kan bladfjederen være fremstillet af ledende materiale til tilvejebringelse af en elektrisk forbindelse mellem stiftelektroden og videopladespilleren 10's signalbehandlingskredsløb 40, fig. 1. I dette 30 tilfælde er den ene ende af bladfjederen 33 fastgjort til stiften 15 på en måde, der etablerer elektrisk forbindelse mellem bladfjederen og stiftelektroden. Signalbehandlingskredsløbet 40 har en indgangsterminal 41, der berører den anden ende af bladfjederen 33, når pa-35 tronen 17 er indeholdt i rummet 18, for at etablere den ovenfor nævnte elektriske forbindelse. Patronen kan være af den i amerikansk patent nr. 4.049.280 beskrevne art.Where the pin 15 contains an electrode for detecting signal variations in the coil groove of the plate 11 during playback, the leaf spring may be made of conductive material to provide an electrical connection between the pin electrode and the video recording player 10's signal processing circuit 40. 1. In this case 30, one end of the leaf spring 33 is attached to the pin 15 in a manner that establishes electrical connection between the leaf spring and the pin electrode. The signal processing circuit 40 has an input terminal 41 which touches the other end of the leaf spring 33 when the cartridge 17 is contained in the space 18 to establish the aforementioned electrical connection. The cartridge may be of the kind described in U.S. Patent No. 4,049,280.
