Abstract
In a thermal color hard copy machine in which only one reversible motor is used for both driving a paper feed mechanism and a printing head driving mechanism for lifting and lowering a printing head thereof relative to a platen, the inertia of the printing head driving mechanism is precisely controlled by an inertia control device. In particular, this inertia control device controls the inertia of a one-way power transmission device generally provided in this type of printing head driving mechanism for precisely stopping the printing head at a predetermined position relative to the platen.
