Abstract
PURPOSE: To arrange so that white piercing of a line or a column may easily be carried out without touching a manuscript by providing an indication device which indicates a white piercing start position and a white piercing ending position on the end of a drum for winding a manuscript.
CONSTITUTION: When a white piercing start indication mark 36 comes in, an output from light receiving elements 39, 40 are both at a high level and an output from AND gate 42 is also at a high level. At the same time, a flip-flop 45 indicates a high level output Q. Next, when a white piercing ending indication mark 37 comes in, an output from the light receiving element 39 is at a low level and an output from a light receiving element 40 is at a high level. At the same time, an output from AND gate 43 is at a high level. Therefore, the flip-flop 45 has its output Q reset at a low level. A white piercing control signal W is applied to a control input for an electronic switch and it is so arranged that when the output Q is a high level, the electronic switch is in "OFF" position. Accordingly, a white piercing is carried out between the white piercing start indication mark 36 and the white piercing end indication mark 37.
