Kind Code:
B2
Abstract:
PURPOSE:To form a photocomposing machine at a low cost by reducing the capacity of its memory by such an arrangement wherein a memory for characters is composed of a memory which corresponds to the entire print area of a sensitized material and another memory for enlarged characters which corresponds to area of several characters. CONSTITUTION:Characters on a character board 1 read out through a main lens 2 are printed on a sensitized material 3, and at the same time, they are enlarged N times by a group of enlarging lenses 5 through a half mirror 4 and projected on a photographing means 6 and image information thus obtained is caused to be memorized in a buffer memory 7. Next, a writing selection circuit 9 causes the image information reduced to 1/N (consequently magnification is 1) by a magnification conversion circuit 8 to be memorized in a character memory 10 and the unchanged image information (consequently magnifacation is N) to be memorized in another character memory 11 and next, the contents of the memory 10 are displayed as they are (all area of sensitized material 3) on a display unit 14 through a reading selection circuit 12 and a refresh memory 13 and the contents of the memory 11 are partially (e.g. only 2 characters) displayed on the display unit 14, while they are being renewed in sequence.
