摘要： PURPOSE:To easily observe transferred characters or graphics without generating a difference in brightness by allowing current to flow with delay in the case of continuously lighting an incandescent lamp has been lighted up immediately before it again out of many incandescent lamps arranged on a display part as compared with the intermittent lighting of a light source. CONSTITUTION:Leading data 6 and regular data 7 are inputted to a trigger circuit 5 connected to a triac 4, and in the case of continuously lighting up a light source 3 has been lighted up immediately before it again, current is allowed to flow with delay as compared with the intermittent lighting of the light source 3. Consequently, the continuously lighting light source 3 and the intermittent lighting light source 3 can be observed so as to be simultaneously illuminated, so that characters or graphics can be observed without generating darkness in the whole picture and the transferring state of the characters or graphics can be observed with the same brightness.
