摘要： An automatic focus adjustment system comprises a focusing device which varies an image forming position; and a control circuit which is capable of setting first and second focusing modes. In the first focusing mode, the control cirucit causes the focusing device to move to an in-focus point within its morning area. In the second focusing mode, the control circuit causes the focusing device to move to an in-focus point on the nearest focusing distance side. The control circuit is arranged to divide a moving range of the focusing device into a first area and a second area which is set on the nearest focusing distance side of the first area to make the focusing device movable within the first area in the first focusing mode, and to make it movable within both the first and second areas in the second focusing mode.
