Abstract

PURPOSE: To obtain an automatic machine for making stencil without producing any color shear, in which photo sensors provided with color filters having different photospectroscopic characteristics are located facing to the original copy and the color selection circuit is provided so that two colors, namely black and other color, can be read out separately.
CONSTITUTION: A reflection light L from the surface of an original copy is directed to photo sensors 3 and 4 provided with color filters 1 and 2 respectively having different photospectroscopic characteristics. Outputs O1 and O2 are converted into P1 and P2 through DC amplifiers 5 and 6. An output signal P1 corresponding to the black color on the original copy is applied on a secondary side Q1 of a transformer 10 via a switch 7 to output a stencil making signal via diodes 12, 13, transformer 11 and power amplifier 15, thus making the stencil for black color. When the sensors 3 and 4 are faced to colors other than black on the original copy, only P2 signal is applied on the secondary side Q1 of the transformer 10 via the switch 7 to output a stencil making signal via diodes 12, 13, transformer 11 and power amplifier 15, thus making the stencil for other colors.
