PURPOSE:To switch modes with a feeling of a light feathre touch without an impulsive sound, by decelerating a small-sized motor to generate a high torque and utilizing normal and reverse rotations of the motor to operate a desired operating rod. CONSTITUTION:Operating levers 41-44 are fixed to operating rods 34-39 by hinges. Plural press pins 56a-56i, plural projecting parts 55a-55i, and plural position detecting pins 57a-57f are arranged on the circumferential face of a rotary cam 55 interlocking with a motor 47. Press pins 56a and 56f are provided in positions shifted from each other by a certain angle, and levers 41-3, 42- 3, 43-3, and 44-3 are fixed to the lower end part of operating levers axially. Levers are brought into contact with detaining members 41-1, 42-1, 43-1, and 44-1, and the lever 41 is provided with detaining pins 41-2, 42-2, 43-2, and 44-2. |
