Description
Die Erfindung geht aus von einer pneumatischen Vorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention is based on a pneumatic device according to the preamble of claim 1.
Eine Vorrichtung dieser Art, soweit sie zum Entfernen von Staub von einem bandförmigen Aufzeichnungsträger dient, ist aus der DE-OS 25 03 221 bekannt. Die Düsen der bekannten pneumatischen Vorrichtung, die eine Saugvorrichtung ist, sind in BewegMngsrichtung des bandförmigen Aufzeichnungsträgers vor und hinter dem Magnetkopf angeordnet. Während des Abspielvorgangs ist der bandförmige Aufzeichnungsträger in Berührung mit den Düsen, vor deren Öffnung er vorbeigezogen wird.A device of this type in so far as it is used for removing dust from a tape-shaped recording medium is known from DE-OS 25 03 221. The nozzles of the well-known pneumatic Devices, which are suction devices, are in the direction of movement of the tape-shaped recording medium arranged in front of and behind the magnetic head. During playback, the is ribbon-shaped Record carrier in contact with the nozzles, before the opening of which it is drawn past.
Die aus der DE-AS 20 61 392 bekannte pneumatische Vorrichtung ist ebenfalls als Saugvorrichtung bei einem Magnetbandgerät ausgebildet. Das Magnetband wird an einem Hohlzylinder quer zu dessen Längsachse und tangential zu dessen Umfang entlang gezogen. Der Hohlzylinder hat beiderseits der Berührungslinie mit dem Magnetband mehrere kreisrunde Öffnungen, die als Ansaugdüsen dienen.The pneumatic device known from DE-AS 20 61 392 is also used as a suction device in a Magnetic tape device trained. The magnetic tape is attached to a hollow cylinder transversely to its longitudinal axis and tangentially drawn along its circumference. The hollow cylinder has on both sides of the line of contact the magnetic tape several circular openings that serve as suction nozzles.
Bei beiden vorgenannten Geräten werden die Staubpartikel von der Oberfläche des Aufzeichnungsträgers durch Saugwirkung eines Unterdrucks an der Düsenöffnung entfernt Dies ist auch der Fall bei dem aus dem DE-GM 78 12 368 bekannten batteriebetriebenen Handgerät, das als Staubsauger ausgebildet ist, zum Entfernen von Staub von der Oberflächen eines scheibenförmigen Aufzeichnungsträgers \or oder während des Abspielvorgangs. Die Düsen sind von einer Bürste umgeben, mit der auf der Oberfläche des Aufzeichnungsträgers anhaftender Staub vor dem Absaugen gelöst wird. Dabei ist nachteilig, daß die Vorrichtung auch während des Abspielbetriebs stets von einer Bedienungsperson geführt und gehalten werden muß.In both of the aforementioned devices, the dust particles are removed from the surface of the recording medium removed by suction of a negative pressure at the nozzle opening. This is also the case with the from DE-GM 78 12 368 known battery-operated handheld device, which is designed as a vacuum cleaner, for Removal of dust from the surfaces of a disk-shaped recording medium before or during the playback process. The nozzles are surrounded by a brush that is used on the surface of the Recording medium adhering dust is released before vacuuming. It is disadvantageous that the The device is always guided and held by an operator, even during playback must become.
Der Erfindung liegt die Aufgabe zu Grunde, Fremdkörper (Staub) von der Oberfläche eines bandförmigen oder scheibenförmigen Aufzeichnungsträgers während des Abspielvorgangs automatisch zu entfernen. The invention is based on the object of removing foreign bodies (dust) from the surface of a tape-shaped or disk-shaped recording medium to be removed automatically during playback.
Diese Aufgabe wird mit der im Anspruch 1 angegebenen Erfindung gelöst.
Mit dem Wegblasen von Staubpartikeln von der Oberfläche des Aufzeichnungsträgers wird auch der
Abrieb des Aufzeichnungsträgers stark vermindert, so daß sich dessen Lebensdauer erheblich erhöhtThis object is achieved with the invention specified in claim 1.
With the blowing away of dust particles from the surface of the recording medium, the abrasion of the recording medium is also greatly reduced, so that its service life is considerably increased
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchsn gekennzeichnet.Advantageous further developments of the invention are characterized in the subclaims.
Mit der im Anspruch 2 angegebenen Weiterbildung der Erfindung wird erreicht, daß der Tonabnehmer (Saphir) bei Plattenspielern oder Magnetköpfe von Tonband- oder Videogeräten nicht verunreinigt werden, weil immer ein sauberer Aufzeichnungsträger abgetastet wird. Dies gewährt eine immer gleichbleibend gute Tonwiedergabe, sowie einen geringen Abrieb und eine lange Lebensdauer von Tonabnehmer und Abtastkopf.With the further development of the invention specified in claim 2 it is achieved that the pickup (Sapphire) are not contaminated with turntables or magnetic heads of tape or video devices, because a clean recording medium is always scanned. This guarantees a consistently good quality Sound reproduction, as well as low abrasion and a long service life of the pickup and scanning head.
Damit die weggeblasenen Staubpartikel nicht vonSo that the dust particles blown away from
dem Gebläse erneut auf die Oberfläche des Aufzeichnungsträgers aufgeblasen werden, wird gemäß Anspruch 6. die Luft für das Gebläse über einen Filter angesaugt.are blown again by the fan onto the surface of the recording medium, is according to claim 6. the air for the blower is sucked in through a filter.
Es ist natürlich ein großer Vorteil wenn, wie im Anspruch 7 angegeben, das Gebläse ein vom AntriebIt is of course a great advantage if, as indicated in claim 7, the fan is one of the drive
so des Aufzeichnungsträgers getrenntes Antriebsaggregat aufweist, weil in diesem Fall die Drehzahl des Plattentellers oder der Tonrolle nicht durch das Gebläse beeinträchtigt wird.so the recording medium has a separate drive unit, because in this case the speed of the The turntable or the sound roll is not affected by the blower.
Mit der im Anspruch 8 angegebenen Ausbildung des Gebläses als Zusatzgerät wird erreicht, daß die Vorrichtung auch nachträglich an Wiedergabegeräte leicht angebaut werden kann.With the design of the fan specified in claim 8 as an additional device it is achieved that the Device can also be easily retrofitted to playback devices.
