Abstract
PURPOSE: To facilitate operation of a photocomposer and to enhance product quality, by installing pulse motors on members for leading light shielding curtains driven with a numerical control computer.
CONSTITUTION: Light shielding curtain 12 undergoes winding action of a coil spring built in core body 15 to be kept always in a stretched state, and it is held with curtain leveler 17 so as to enable foreward and backward motion on and in close contact with extremely thin transparent plate 2. member 8 for leading curtain 12 is provided with pulse motor 11 having on its shaft 10 spur gear 9 engaged with rack gear 7 and moving on it, and member 8 is fixed to the end of extremely thin reinforced plate 13 attached to the upper surface of the end of curtain 12 till the almost central part, and guide shaft 14 is laterally provided to allow motor 11 and gear 9 to move on gear 7 in parallel to shaft 14. Above mentioned curtain 12, body 15, member 8, gears 7, 9 motor 11, plate 13, shaft 14, etc. are provided in 4 sets. Thus, operation of a photocomposer can be facilitated, and product quality can be enhanced both to a large extent by driving each of these pulse motors with an numerical control computer.
