MAGNET TYPE INPUT DEVICE CAPABLE OF CHANGING OPERATIONAL FEELING OF KEY AND PORTABLE COMPUTER

摘要

PROBLEM TO BE SOLVED: To provide a magnet type input device capable of customizing a tactile.SOLUTION: Holding magnets 161a-161c attached to a horizontal slider 109a position the keys 105a-105c attached to a key magnet 171a at a ready position. Relative position of the holding magnets and key magnets at the ready position can be changed by changing the position of the horizontal slider. The attraction force is maximum in Fig. 10(A), and minimum in Fig. 10(C). Since the attraction force at the ready position determines the yield point of reaction when the depressed key is settled, the user can customize the tactile by changing the horizontal slider.
