Description

Bildwerfermaschine Der Gegenstand der Erfindung betrifft eine Bildwerfermas.chine, die durch einfaches Anfügen eines kein Filmtransportmittel enthaltenden Lichttongerätes ,auch zum Vorführen von Tonfilmen geeignet ist. Dabei treten insofern Schwierigkeiten auf, als die zum Transport des Films durch das Tongerät allein in Frage kommende Na.chwickeltrommel mit ihrem schwungradlosen Antrieb nicht geeignet ist, den Tonträger mit genügender Gleichförmigkeit durch das Tongerät zu ziehen, so daß leicht Tonstörungen auftreten können.Image projector machine The object of the invention relates to a projector machine, by simply adding a light sound device that does not contain a film transport means , is also suitable for showing sound films. In this respect, difficulties arise than the one that can be used to transport the film through the sound device alone The winding drum with its flywheelless drive is not suitable for the sound carrier to pass through the sound device with sufficient uniformity, so that sound disturbances easily may occur.

Aus diesem Grunde wird vorgeschlagen, die Nachwickelrolle der Stummbildwerfermaschine mit einer Schwungmasse zu kuppeln und nachgiebig anzutreiben. Man kann so die Maschine ohne weiteres als Stummbildmaschine verwenden und braucht nachträglich keine Eingriffe in das Antriebswerk zu machen, wenn man die Maschine durch Anfügen eines Tongerätes auch zum Vorführen von Lichttonfilmen benutzen will.For this reason, it is proposed to use the rewinding roll of the silent projector machine to couple with a flywheel and to drive flexibly. You can use the machine like that can easily be used as a silent imaging machine and does not need any subsequent changes to make in the drive mechanism when you start the machine by attaching a sound device also want to use it for showing optical sound films.

Als bekannt wird vorausgesetzt, da.ß man Filmförderrollen bereits mit Schwungmassen verbunden und nachgiebig .angetrieben bat, um einen gleichförmigen Filmlauf an der Toinsteu@erstelle zu erreichen. Erfindungsgemäß wird ,also die Nachwickeltrommel eines Stummbildwerfers von vornherein mit dem für die Tonfilrnwiedergabe benötigten Schwingungsfilter versehen, um eine nachträgliche Umstellung der Maschine auf Tonfilmwied.ergabe zu vereinfachen.It is assumed to be known that one already has film feed rollers connected with flywheels and yielding .driven asked for a uniform To reach the film run at the Toinsteu @ create. According to the invention, so the rewinding drum a silent projector from the outset with that required for sound film playback Vibration filters are provided to enable the machine to be converted to sound film playback at a later date to simplify.
