Abstract

PURPOSE: To check the suitability of a type wheel attached to an output shaft of a motor for type selection, by a method wherein a time required for the rotation of the type wheel is measured, and the measurements are compared with a reference time corresponding to a specified type wheel.
CONSTITUTION: When a start command for printing operation reaches, a rotation amount n is set at a counter 16, and a speed decision circuit 11 turns a DC motor 13 via a motor drive circuit 12 at a speed corresponding to a type wheel data and the rotation amount n instructed through a set switch 20 by an operator. A rotation detecting signal (a) is generated at a position detector 14, a count pulse (b) reaches a pulse counter 16 from a pulse converter 15, and a measurement starting signal (c) and a measurement finish signal (d) are transmitted to a time measurement circuit 17 to store a measurement time Ta. The measurement time Ta is compared with a reference time Tb at a time comparison circuit 19, and when the result is Ta≠Tb, a printing operation is stopped.
