Printer and its driving control method

Title of Invention: Printer and its Drive Control Method Patent Application Number Abstract: The present invention provides a movable type selection printer. Its main feature is that it is driven by a direct current motor to rotate a movable type rotating wheel on the outer surface for printing a plurality of movable types. The voltage conversion circuit converts the voltage supplied from the power source into a multilevel motor drive voltage value. The driving motor circuit drives the DC motor from the motor driving voltage value supplied through the voltage conversion circuit. The temperature detector detects the temperature of the location in the printer. The drive control circuit compares the detected temperature detected by the temperature detector with the set temperature, and controls the voltage conversion circuit to reduce the motor drive voltage value when the detected temperature exceeds the set temperature.
