Abstract

PURPOSE: To perform index signal processing with only the index signal having single frequency by obtaining a signal having large output in relation to the first index fluorescent stripe.
CONSTITUTION: The first index fluorescent stripe 5a is formed wider than the similar stripe 5b of others. Accordingly, the output of a photoelectric converter 6 generates large output at the part corresponding to the stripe 5a, and the output of a bypath filter 7 shows the similar tendency. In this case, the threshold value of a comparator 8 can be set fairly high, so wrong operation of the comparator 8 due to noise can be prevented. Even if the threshold value is set too high and the index signal due to the succeeding stripe 5b can be obtained, the first index signal is favourably obtained as the T input of D-FF9, but in this case, noise component should be of the degree negligible. Thus, index signal can be treated simply without being affected by noises.
