PROBLEM TO BE SOLVED: To make a presentation device with a movable member disposed inside a casing with an openable/closable lid perform complicated motions while reducing the cost by operating the presentation device using a motor as one driving means. SOLUTION: The lid 212 of the presentation device 20 is opened with the operation of a first cam member 220 by driving the motor 201, and the arm-shaped movable member 250 is lifted up toward the lid 212 from inside a box 211 of the presentation device 20 with the operation of a second cam member 230 by continuously driving the motor 201. Then, the lifted arm-shaped movable member 250 is swivelled out of the box 211 by further driving the motor 201. When the arm-shaped movable member 250 is swivelled to the maximum swivelled position, the arm-shaped movable member 250 is returned to the original swivelled position with the contractive elasticity of a third spring 263 and lowered into the box 211. Then, the lid 212 is closed. COPYRIGHT: (C)2008,JPO&INPIT
