Abstract

PURPOSE: To ensure the selection, by increasing the torque of motor, through the frequency division of the drive pulse when larger torque is required, by using the characteristics of pulse motor for page sheet selection set.
CONSTITUTION: The page selection switch 18 is depressed and the coded signal with the encoder 19 is fed to the comparator 21. The comparator 21 compares this signal with the signal at the position detector 14, controlling the motor drive circuit 16 and starting the motor 9, resulting in drawing out the page steet. If the movement of page sheet is slown down with friction, disagreement is caused when the number of pulses in driving the motor and the conversion value of the drive pulses for the distance between the position detection marks for every page(content of memory 26) are compared with the comparator 27. This time frequency division circuit 24 feeds the drive pulse being lower frequency to the motor drive circuit 16. Thus, when larger drive torque is required, the drive torque can be increased by frequency-dividing the pulses.
