Abstract

A cassette has two reel cores between which a magnetic tape can be moved back and forth. The magnetic tape is attached to the second reel core via a tape end section with the aid of a sticker. In the same way, the magnetic tape is attached to the first reel core. At least one of the stickers 20 is provided with a regular pattern of highly reflective R and less reflective N zones. The pattern ends with an N zone on one side and with an R zone at the other side. <IMAGE>

Description

"Cassette voorzien van magneetband""Cassette with magnetic tape"

De uitvinding betreft een cassette zoals door Aanvrager eerder beschreven in NL 9100126, zijnde een cassette voorzien van een eerste en een tweede spoel-kem en een hoeveelheid tussen de spoelkemen transporteerbare en op de spoelkemen wikkelbare magneetband alsmede een met de eerste spoelkem verbonden eerste eindbandstuk en een met de tweede spoelkem verbonden tweede eindbandstuk, welke eindbandstukken ieder door middel van een plakker met de magneetband zijn verbonden, waarbij althans één der beide plakkers is voorzien van een optische door een apparaat geschikt voor het afspelen van de magneetband detecteerbare streepjescode omvattende een aantal dwars op de lengterichting van de magneetband verlopende streepjes.The invention relates to a cassette as described earlier by the Applicant in NL 9100126, being a cassette provided with a first and a second coil core and an amount of magnetic tape which can be transported between the coil cores and which can be wound on the coil core, as well as a first end tape piece connected to the first coil core and a second end tape piece connected to the second reel core, said end tape pieces each being connected to the magnetic tape by means of a sticker, at least one of the two stickers being provided with an optical bar code detectable by an apparatus suitable for playing the magnetic tape, comprising a number of transverse stripes running along the length of the magnetic tape.

Zoals in de eerdere aanvrage reeds beschreven, kan de streepjescode zodanig zijn ontworpen dat de detectormiddelen, die in een apparaat aanwezig zijn voor het detecteren van de code, een onderscheid kunnen maken tussen de twee mogelijke transportrichtingen van de magneetband.As already described in the previous application, the bar code can be designed such that the detector means, which are present in an apparatus for detecting the code, can distinguish between the two possible transport directions of the magnetic tape.

De huidige uitvinding betreft een verdere uitvoeringsvorm van de in de aanhef genoemde cassette waarbij de code een bijzonder eenvoudige en dus ook eenvoudig te detecteren vorm heeft en heeft tot kenmerk, dat de streepjescode bestaat uit een regelmatig patroon van afwisselend meer en minder reflecterende zones, waarbij het patroon aan de ene zijde begint met een meer en aan de andere zijde eindigt met een minder reflecterende zone.The present invention relates to a further embodiment of the cassette mentioned in the preamble, in which the code has a particularly simple and thus also easily detectable form, and is characterized in that the bar code consists of a regular pattern of alternately more and less reflective zones, wherein the pattern on one side starts with a lake and on the other side ends with a less reflective zone.

De uitvinding zal worden toegelicht aan de hand van de figuur.The invention will be elucidated with reference to the figure.

De magneetband 7 is verbonden met een niet magnetisch eindbandstuk 13A. De plakker 20 is voorzien van een regelmatig patroon van afwisselend goed reflecterende zones R en nauwelijks reflecterende zones N. Aan het rechter einde eindigt het patroon met een R-zone en aan het linker einde met een N-zone.The magnetic tape 7 is connected to a non-magnetic end tape piece 13A. The patch 20 is provided with a regular pattern of alternately well-reflecting zones R and hardly reflecting zones N. At the right end, the pattern ends with an R zone and at the left end with an N zone.

1. Cassette voorzien van een eerste en een tweede spoelkem en een hoeveelheid tussen de spoelkemen transporteerbare en op de spoelkemen wikkelbare magneetband alsmede een met de eerste spoelkem verbonden eerste eindbandstuk en een met de tweede spoelkem verbonden tweede eindbandstuk, welke eindbandstukken ieder door middel van een plakker met de magneetband zijn verbonden, waarbij althans één der beide plakkers is voorzien van een optische door een apparaat geschikt voor het afspelen van de magneetband detecteerbare streepjescode omvattende een aantal dwars op de lengterichting van de magneetband verlopende streepjes, met het kenmerk, dat de streepjescode bestaat uit een regelmatig patroon van afwisselend meer en minder reflecterende zones, waarbij het patroon aan de ene zijde begint met een meer en aan de andere zijde eindigt met een minder reflecterende zone.1. Cassette provided with a first and a second coil core and a quantity of magnetic tape which can be transported between the coil cores and which can be wound on the coil core, as well as a first end band piece connected to the first coil core and a second end tape piece connected to the second coil core, each end tape pieces by means of a adhesive tape are connected to the magnetic tape, at least one of the two stickers being provided with an optical barcode detectable by an apparatus suitable for playing the magnetic tape, comprising a number of stripes running transversely of the longitudinal direction of the magnetic tape, characterized in that the barcode consists of a regular pattern of alternately more and less reflective zones, the pattern beginning on one side with a more and ending on the other side with a less reflecting zone.
