PURPOSE:To improve the responding characteristic by alternately superposing Peltier elements and shape memory alloys to form a deforming element, absorbing heat and heating from both side of the alloys with the elements, thereby regulating the responding speed in a wide range. CONSTITUTION:Shape memory alloys 8a, 8b for storing two types of different shape and Peltier elements 18a, 18b are bonded in a laminar state to form a composite element 8. The shape memory alloys 8a is heated by the elements 18a, 18b, the alloy 8b is cooled to set the alloy 8a to the transition point or higher and the alloy 8b to the transition point or lower. An operating lever 11 in which the shape that the alloy 8a is stored is drawn rightward. Since the polarity of the current flowed to the elements 18a, 18b alters when the switch 15 is switched, the heating surface and the heat absorbing surface are inverted. The shape stored by the alloy 8b is presented, and the lever is pressed rightward. The current flowed to the element is controlled to select the responding speed in a wide range. |
