ABSTRACT:
A lamp mounted on a first carriage emits light onto an original placed on an original table. A photoelectric converter converts light reflected by the original into an electrical signal by using mirrors, a zoom lens, and the like mounted on a second carriage. In accordance with the electrical signals supplied from the photoelectric converter via a control unit, a thermal head transfers inks from an ink ribbon onto paper wound around a platen drum to form an image corresponding to an original image on the paper. An operation panel has a magnification-set key for setting the magnification of an image to be formed by the thermal head. A stepping motor drives the first and second carriages. When the magnification set by the magnification-set key falls within a predetermined range, a motor drive in the control unit sets the speed of the stepping motor to a high speed and supplies a high current. When the magnification exceeds the predetermined range, the motor driver sets the speed of the stepping motor to a low speed and supplies a low current.
