<p>PROBLEM TO BE SOLVED: To provide a motion mechanism of a movable accessory device, capable of converting a motion of a drive transmission member in a rotation direction into a complicated motion of a movable member.SOLUTION: A motion mechanism of a movable accessory device includes: a plate-like member 130 (a drive transmission member) provided with a plate first shaft part 132 and a plate second shaft part 133 in positions eccentric from a rotation center thereof; a first movable member 140 provided with a first right opening part 161 with which the plate first shaft part 132 provided in the plate-like member 130 slidably engages; and a second movable member 150 provided with a second cutout part 183 with which the plate second shaft part 133 provided in the plate-like member 130 detachably engages. When the plate-like member 130 rotates from an origin position to a first spot (a B point), and when the plate-like member 130 rotates from the first spot to a second spot (a C point), the motion mechanism transmits drive force from a motor 120 through one of the plate first shaft part 132 and the plate second shaft part 133.</p> |
