  • SPECIFIC DESCRIPTION The machine illustrated is of the kind having a rotatable matrix disk Z'carryingaplurality of symbols l,.shown.as letters, imageof whichareprojected selectively onxphotosensitive material, e.g. film or paper, on av drum 49.
  • Symbol selection is effected in known manner by rotation of disk2 tobring theselected symbolinto the path ofv light from a lamp 4.
  • the light path extends fromlamp 4 to the photosensitive material by way of an optical system'comprising a condenser 5, an electromagnetic shutter (not shown), a prism 44, reversing prism 45, lens 46,. reversing prism 47 and prism 48.
  • drum-49 is rotated to prevent unexposed material. from imaging of; the further symbol; the amount, of rotation, i.e. the symbol spacing on the photosensitive material, is-controlled inamanner to be described, by index. marks 3associated with the individualsyrnbols ondisk 2.
  • Rotation of drum 49 is effected by' a. stepping motor 56 through a. splined shaft Imeshingwith a. gear 54fixed to drum49'.
  • the drum 491s journalled in a: carrier 50 for axial movementalong a slide 5 under the action of a lead. screw. 53', for the image-forming of successive lines of symbols.
  • Prisms44; 48, and-lens 46 are'carried by a'stationary support 39 which also carries a guide rail 38 along whichcan slide supports 25; 40'carrying prisms 47, 45 respectively.
  • the supports are interconnected by a linkage 4.1 such that on movement of support 25 the image projected into the photo-sensitive material will I selected symbol 1 into the light path, and is then locked inpositionwhilezthe symbol is imaged on the'photosensitive material. In this position of the disk 2, the index mark 3-associated with the selected symbol 1 isalso illuminated, by the same or an additional optical system.
  • the mark 3 is illuminated by lamp 4 via lenses 5, 6 but the mark 3 is imaged at a phototransducer 9 via a mirror 7 which can pivot to scan (sweep) the sharp image 3 of the mark 3 widthwise onto the phototransducer 9, thereby causing the latter to provide an output pulse.
  • Pivoting of mirror 7 is effected by a long lever arm 8 rigid with the mirror which arm bears on a knife-edge 16 by way of a pin 17.
  • This pin is carried by an arm 18 pivoted at its end support to a block 25 so that when the block 25 is moved to vary the symbol image size, the pin moves along lever 8 and knife-edge 16, thereby changing the effective length of lever 8 and the angle through which mirror 7 is pivoted for a given movement of knife-edge l6.
  • a rocker plate incorporating knife-edge 16 is rocked at a predetermined rate by a continuously rotating synchronous motor 10, driving plate 15 through an electromagnetic clutch 11, shaft 12, pinion l3, and a toothed sector 14 on plate 15.
  • Mirror 7 is thereby pivoted, at an angular rate dependent on the setting of knob 26, to cause transducer 9 to provide an output pulse.
  • the time elapsing before the provision of the output pulse is a measure of the symbol spacing as represented by the mark 3.
  • Operation of knob 26 to vary the symbol image size automatically varies this time and hence the symbol image spacing, owing to the coupling of pin 17 to support 25.
  • This elapsed time is measured by means of a transparent disk 22 carrying uniformly spaced markings 23 and mounted on shaft 12. Initially a stop arm 19 on shaft 12 lies against an adjustable stop pin 20, owing to the weight of the rocker plate, when clutch 11 is engaged to rock the plate and thereby scan image 3' onto transducer 9, disk 22 rotates with shaft 12 and the markings 23 are scanned by a photosensitive transducer 24 to generate an electrical pulse train; this pulse train is terminated when transducer 9 receives image 3' and emits an output pulse. The number of pulses in the train therefore represents the elapsed time and hence the symbol image spacing.
  • the pulses in the train are recorded in digital form in a register 31 and stored in a second register 32.
  • the disk 2 is unlocked and can then be rotated for selection of a further symbol.
  • the value stored in register 32 and representing the symbol image spacing is read out and applied through circuitry of a conventional nature to control the step motor 56, in such a way that the motor 56 rotates drum 49 through an angle corresponding to the appropriate spacing.
  • the stop pin 20 is carried by a worm wheel 21 which can be rotated, through worm 30 by means of a knob 29 with uniform graduations thereon.
  • a knob 29 By rotation of knob 29, the initial position of arm 19 and hence of mirror 7 can be adjusted to increase or decrease the spacing of each symbol image by a predetermined constant amount.
  • the mark 3 may represent the desired spacing in analogue fasion by its position on disk 2, or by its width or any other convenient attribute. It may be sensed or scanned optically, mechanically, electrically or in any other convenient way. In the case of the machine illustrated, the spacing is represented by the separation of the mark from an actual or imaginary zero position associated with the symbol and in the same position with respect to each symbol; the zero position may for example correspond to an edge of the symbol, or to a reference mark controlling the locking of the disk in position.
  • a machine as claimed inclaim 1 including image adjusting means for adjusting the size of the symbol image on the photosensitive material, said adjusting means being coupled to the intermediate member for automatically adjusting the image spacing in accordance with adjustment of the image size.
  • a photocomposition machine comprising:
  • optical means defining a symbol-selection station for transmitting an image of a selected symbol to an image-forming station; means for displacing said matrix relative to said selection station for positioning a selected symbol at said selection station; transport means for displacing a photosensitive material at said image-forming station;
  • scanning means for scanning the mark associated with the selected symbol at said selection station and producing a signal representing the scan of the mark
  • said scanning means including means for angularly sweeping a light beam across said mark
  • stepless transmission means between said means for sweeping said beam across said mark and said signalgencrating means and adjustable to vary the output of said signal-generating means in a predetermined relationship to the angle swept by said beam across said mark.
  • said means for sweeping said beam across said mark includes a swingable reflector, an arm rigid with said reflector, an intermediate member engageable with said arm for transmitting movement thereto to swing said reflector and means for adjusting the effective length of said arm.
