Description

10 15 20 25 30 513 839 2 kännetecknande del angivna särdragen. 10 15 20 25 30 513 839 2 characteristic part specified features.

I åskådliggörande syfte skall nu en föredragen utföringsform av uppfinningen närmare beskrivas i anslutning till bifogade Figur 1. Denna figur visar en filmkassett enligt uppfinningen i perspektivvy snett framifrån. i I figuren betecknas en stiliserat framställd filmkassett med 1. Denna kan vara av varje på marknaden vanligen förekommande fabrikat. Ur en slits 2 i kassetten sticker på känt sätt en flik 3 av själva filmrullen ut. På grundval av denna flik kan man omöjligt avgöra om filmen är exponerad eller oexponerad.For illustrative purposes, one should now be preferred embodiment of the invention is described in more detail in connection to the attached Figure 1. This figure shows a film cassette according to the invention in perspective view obliquely from the front. in The figure denotes a stylized representation film cassette with 1. This can be of any on the market common brands. From a slot 2 i the cassette sticks a tab 3 of itself in a known manner the film roll out. On the basis of this tab you can impossible to determine if the film is exposed or unexposed.

Det väsentliga särdraget hos föreliggande uppfinning är att filmkassetten redan vid dennas tillverkning försetts med en anordning 4, vilken i det visade utföringsexemplet är en vidhäftande remsa av lämpligt material, såsom papper, metallfolie eller olika syntetiska polymermaterial, såsom cellofan, teflon, polyeten, etc. Vanlig tejp och olika färgade tejpsorter går också utmärkt. Den vidhäftande remsan kan även förses med en perforerad rivlinje 5.The essential feature of the present invention is that the film cassette is already at its manufacturing is provided with a device 4, which in it shown embodiment is an adhesive strip of suitable material, such as paper, metal foil or various synthetic polymeric materials, such as cellophane, Teflon, polyethylene, etc. Plain tape and various colored tapes also work great. The adhesive strip can also be provided with a perforated tear line 5.

Man inser lätt att för att den oanvända filmen över huvud taget ska kunna användas, måste man avlägsna den vidhäftande remsan, eller om remsan innefattar en perforerad rivlinje, måste man först riva av remsan innan kameran kan laddas. Om en remsa med rivlinje används, kan den del som vidhäftar på själva filmfliken antingen få sitta kvar eller avlägsnas. För att underlätta avlägsnandet av den vidhäftande remsan från kassetten och/eller filmfliken, kan en mindre änddel av remsan utformas utan vidhäftande gummering, för att man på så sätt lättare ska få fatt i remsan och dra bort den. lO 515 839 3 Anordningen 4 behöver inte uppvisa formen av en remsa. Den kan vara tillverkad av ett stycke vidhåftande material med godtycklig geometrisk form, såsom rund, trapetsoid eller triangulär. Det väsentliga är att den vidhäftar både filmkassetten och filmfliken.One easily realizes that to the unused movie over to be used at all, it must be removed the adhesive strip, or if the strip comprises a perforated tear line, one must first tear off the strip before the camera can be charged. About a strip with tear line used, the part that adheres to the film tab itself either allowed to remain or removed. In order to facilitate the removal of the adhesive strip from the cassette and / or film tab, a smaller end portion of the strip is designed without adhesive rubber, to man in this way it will be easier to get hold of the strip and pull away the. lO 515 839 3 The device 4 need not have the shape of a strip. It can be made of one piece adhesive material of any geometric shape, such as round, trapezoidal or triangular. The essentials is that it attaches both the film cassette and the film tab.

Man kan även tänka sig en ändlös remsa, som går runt hela kassetten.One can also imagine an endless strip, which goes around the entire cassette.

Genom föreliggande uppfinning utesluts således risken med att man glömmer att markera huruvida en film är använd eller inte, vilket kan hända exempelvis vid uppfinningen enligt den svenska patentansökan 9101645-1.Thus, the present invention excludes the risk of forgetting to mark whether a movie is used or not, which can happen for example at the invention according to the Swedish patent application 9101645-1.
