Abstract: A mechanism for automatically taking up film strip material on to a driven spool comprises a fixed guide to direct the film around the spool, and a pivotally-mounted guide for directing the film back on to itself so the leading end is entrained between the spool and a remote portion of the film. The mechanism is contained within a cassette having an inlet slot for directing the film through nip rollers to the fixed guide.

Abstract: Apparatus for recording characters displayed on the screen of a cathode ray tube on an elongate record member has a stepper motor for advancing the record member on completion of a line of the character, recording being carried out substantially continuously by positional adjustments of the characters on the screen. Performance of the apparatus in response to record member advance instructions is monitored by a first transducer, which may be a digitizer, connected either to the stepper motor output shaft or to a spool from which the record member is unwound and by a second transducer, which may be driven by the record member or which may also be connected to the spool. The transducer signals are used to influence the position of the displayed characters on the cathode ray tube screen.
