    摘要: A printer with a plurality of ink ribbon cassettes is capable of printing characters or designs with a selected one of these ink ribbon cassettes. The printer includes a vertically movable cassette table on which the plurality of ink ribbon cassettes are mounted in a stacked relationship, a stepping motor, and a rotary cam mechanism for moving the cassette table up and down when the stepping motor drives to rotate the rotary cam mechanism. There is further provided a memory for pre-storing the rotational speed data for each rotational angle of the rotary cam mechanism according to a variation pattern of load applied to the stepping motor together with the rotation of the rotary cam mechanism. The rotational speed of the stepping motor is controlled accoding to the rotational speed data corresponding toe ach rotational angle of the rotary cam mechanism read out of the memory.
