| 摘要 | PURPOSE: To prevent the malfunction based on an artificial operation of an operating part by heating a first shape memory alloy to take a prescribed shape at the time of operation control of the operating part, and moving an operation control member to an operation control position. CONSTITUTION: A device controller 5 executes the driving control of a heating means of heater parts 5a, 5b. At the time of operation control, that is, when it is not desired that a button 1 is pushed in, the device controller 5 heats instantaneously a shape memory alloy of 4a through a heater part 5a to the button 1, and when the shape memory alloy 4a of the outside is heated instantaneously, a plate 3 is allowed to slide to the lower part of the botton 1, and the plate 3 works as an operation control member for controlling an operation of the button 1. On the other hand, at the time of operation of the button 1, a shape memory alloy 4b expands by being heated by the heater 5b, and the plate 3 is allowed to slide to the outside of the button 1. In such a way, the malfunction of the operating part 1 can be prevented simply and surely. COPYRIGHT: (C)1992,JPO&Japio |
