Carriage drive unit for avoiding a loss time period in a printer

摘要

A carriage drive unit for a printer includes a typewheel and a printing hammer for striking a type element of the typewheel against a ribbon to reproduce the type element on a printing paper, both of which are provided on a carriage. The carriage is driven by a carriage drive motor in response to a drive control signal SG2 output by a CPU, before the printing hammer, which is driven by a hammer drive motor in response to a drive control signal SG5, reaches a printing position, for avoiding a loss time period due to a carriage response delay upon a start of the carriage drive motor.
