Photocomposition machine |
摘要 |
A photocomposition machine wherein the lens system includes at least one focusing lens which is moved into point size position by a mechanical drive under a control means which returns the lens carriage to a known reference position prior to a composition routine, which reference position becomes a value in the memory of the control, whereby the mechanical precision and wear alteration of the drive become of no factor in accurate focusing of the lenses.
