The device also contains a connection that generates pulses with a period T l corresponding to the movement of paper by a specified amount, for example, 0.6. If contact 24 is then closed in counter 15 and 11, then output pulses appear at the output of divider 2, the duration and duty ratio of which are set to N dividing from the setter divider-23.

If, for example, N 10, C 2, the duration of the pulses at the output of the body of bodies 23 is ten, the period of their rotation is twenty periods of the pulses of the sensor 10.

The signal from splitter 23 is amplified in amplitude by power amplifier 26 and through a divider on resistors 17 and 19, an emitter follower on transistor 21, resistor 20 arrives
