Specifically, the control unit 15 may perform control such that the change of the drive voltage when changing from one of the drive voltages E1 and E2 to the other becomes a pulse wave having a predetermined gradient. That is, in the peripheral region 112, the change in the drive voltage when the operation position moves from one of the knot portion 113 and the ridge/valley portion 114 to the other does not need to have a gradient, as shown in FIG. 10A. As shown in FIG. 12, it may have a predetermined gradient. As shown in FIG.
  • the frictional force in the peripheral region 112 is as shown in FIG. 10B without a gradient between the driving voltages E1 and E2. As with the changing control, it falls within a predetermined range.

Abstract

L'invention porte sur un dispositif d'entrée comprenant : une unité de commande (10) comportant une surface de commande (11a) qu'un opérateur utilise à l'aide d'un corps de commande (F) ; une unité de détection (12) qui détecte une position de commande pour le corps de commande sur la surface de commande ; une unité d'entraînement (13) qui fait vibrer la surface de commande ; et une unité de commande (15) qui, sur la base d'un signal de sortie de l'unité de détection, applique une tension d'entraînement prescrite à l'unité d'entraînement et entraîne celle-ci. Une onde stationnaire est générée sur la surface d'opération à l'état mis en vibration. La surface d'opération sur laquelle l'onde stationnaire est générée comporte : des jonctions (113) qui comprennent une section dans laquelle aucune fluctuation ne se produit dans une direction orthogonale, c'est-à-dire la direction normale par rapport à la surface d'opération lorsqu'elle est dans un état non vibrant ; et des sections de montagne et de vallée (114) qui présentent une plus grande fluctuation dans la direction orthogonale que les jonctions. L'unité de commande fait varier la tension d'entraînement en fonction de la position de fonctionnement sur la surface de travail par rapport aux données de coordonnées des sections de bosses et de creux et des jonctions.
