When the Image Shifting key (forward key = SW216) is pressed, CNI 02-37 becomes
22V and CN 102-36 becomes OV. Thus, the image shifting motor turns clockwise. (View
from A as show next page.)
On the other hand, when the Image Shifting key (backward key = SW220) is pressed,
CNI02-36 becomes 22V and CNI02-37 becomes OV. Thus, the image shifting motor
turns counterclockwise. (View from A as shown next page.)
