Abstract
A detection means is provided for generating an analog signal in response to a rotation angle of a servomotor which drives a carriage in a printer. A servomotor drive circuit is responsive to a print command from an input means and the analog signal from the detection means, whereby the carriage is driven to travel forward upon receipt of the print command and to stop upon receipt of a print termination signal. The carriage is then held stationary at a predetermined position suitable for the next character to be printed as determined by the rotation angle of the servomotor which is fed back to the servomotor drive circuit.
