PROBLEM TO BE SOLVED: To improve easiness in assembling of a common board unit which can control different types of units and, at the same time, to reduce the total cost of the board unit by making connection between the board units easier with high area efficiency and reducing the areas of exclusively used board potions of the units to the minimum. SOLUTION: A unit for active AF and another unit for passive AS are made controllable by means of a CPU 61 mounted on a control board 35 composed of a hard board. A flexible board 35 for relaying is constituted so that a signal line which controls the units for active and passive AFs may be drawn out. When the flexible board 36 is connected to the control board 35 by shifting the connecting position of the board 36 with the board 35 in a prescribed direction, the CPU 61 controls the unit for active AF or the unit for passive AF. |
