Abstract

PURPOSE: To obtan the print of even and high quality among chracters by measuring the accuracy of type position on a print wheel actually installed by a wheel senser, and using these measurement results as address in selecting the type.
CONSTITUTION: The print wheel is installed on an electric motor 2 for type selection and the wheel sensor side 5 is connected by an operating correction change-over switch 16. Then the print wheel is caused to turn once by driving the electric motor 2 and an actual type position is detected by means of sensor 5. Output of the sensor 5 and a regular equally divided clock signal generated by a motor sensor 4 simultaneously are compared and collated. If the actual type address is different from anticipated value address, the actual type position address is caused to be memorized in an address register 10.During ordinary printing operation, the switch 16 is left connected to the sensor 4 side. When the type different from anticipated value address is selected, the rotation and stop of the print wheel is controlled by actual value address memorized in the register 10.
