Abstract

PURPOSE: To make a detection operable in high precision, with an error operation eliminated due to a noise, by such means that, with a character position detection mark of constant area provided for every character pattern, and its scanning and integration processed, a passing to process be made through the sample hold circuit.
CONSTITUTION: When selectively reading a character pattern by a light or electron beam, a square character detection mark 31 is set correspondingly to each character pattern 2 on a character plate 1. And this mark 31 is made scanning by a beam to obtain a video signal, further with an integration made by an integrator 4. Subsequently with a processing made through a first sample hold circuit 5 and second sample hold circuit 6, a comparison is operated by a comparator 8 between levels of the present scanning and the preceding scanning. Accordingly, a determination of the slide level is not required, further with a less effect of noise by integration processing the video signal, thus a detection of the character position can be performed in high precision.
