タ。[Claim for Utility Model Registration] Character wheels for multiple digits are rotatably supported on a rotary shaft whose both ends are fixed to a counter frame, and the lowest character wheel is operated in mechanically intermittent step motion using electric pulse signals. In a stepper motor-driven counter driven by a stepper motor to be converted, the stepper motor has N
A magnet rotor having a magnet whose south pole is continuously magnetized, a stator having a ring coil provided concentrically around the magnet rotor, and upper and lower yokes made of a magnetic material surrounding the ring coil. The upper and lower yokes are bent along the inner periphery of the annular coil so as to alternately mesh with each other in a comb shape, and have a number of pole teeth equal to the number of magnetic poles of the magnet rotor, and the adjacent pole teeth are magnetically separated by a gap, and each pole tooth is shaped to rotate the magnet rotor in one direction by alternately switching the poles generated in the pole teeth of the upper and lower yokes by energizing the annular coil. A stepper motor driven counter characterized by:
