Abstract
The lens moving mechanism of a printing/developing apparatus has a pulse motor for moving the holding member of the exchangeable lens in the directions X and Y to finely adjust the position of the lens. The lens moving mechanism is controlled by a computer. The movement and position of the lens are specified by inputting numeric values, thus adjusting the position freely. The specified position of the lens is stored as channel data corresponding to each print channel.
