Definitions

  • the sliding member may have a first stopper that restricts movement of the sliding member in the second direction at a position different from the protrusion in the second direction in which the key extends.
  • the hammer assembly 200 includes a metal weight portion 230 on the back side of the rotation shaft 520.
  • the weight portion 230 In a normal state (when the key is not pressed), the weight portion 230 is placed on the lower stopper 410, and the front end portion 210 of the hammer assembly 200 pushes the key 100 back.
  • the weight portion 230 moves upward and collides with the upper stopper 430.
  • the hammer assembly 200 applies weight to the key depression by the weight portion 230.
  • the lower stopper 410 and the upper stopper 430 are formed of a buffer material or the like (nonwoven fabric, elastic body, etc.).
  • the second key guide 153 extends below the key 100 at the front end of the key 100.
  • the second key guide 153 has a plate-like portion.
  • the upper end of the second key guide 153 enters the recess 150 and is connected to both side walls of the recess 150 in the scale direction. With this structure, the mechanical strength of the second key guide 153 with respect to the scale direction is improved.
  • the second key guide 153 sandwiched between the second frame guides 513, the second key guide 153 and the second frame guide 513 slide.
  • a hammer support 120 is connected below the second key guide 153.
  • the region where the projection 620 of the sliding member 600 is provided does not have flexibility in the first directions D1 and D4, the sliding member 600 will rattle against the first frame guide 511. .
  • the key 100 is wobbled.
  • the region where the protrusion 620 of the flexible sliding member 600 is provided is bent in the first directions D1 and D4, the first frame guide 511 and the protrusion 620 The gap between them disappears. As a result, rattling of the sliding member 600 with respect to the first frame guide 511 can be suppressed.
  • a keyboard device 1A including a first guide 51A having a configuration different from that of the first guide 51 in the first embodiment will be described.
  • FIG. 19 is a cross-sectional view of the first guide in one embodiment of the present invention.
  • the first guide 51D shown in FIG. 19 is similar to the first guide 51B shown in FIG. 17, but the first guide 51D is provided with a recess 5119D on the upper surface of the column 544D. It differs from the first guide 51B in that a part of the inner wall is the first frame guide 511D.
  • the first key guide 151D is inserted into the recess 5119D.
  • the sliding member 600D is disposed along the wall surface of the recess 5119D. In other words, the sliding member 600D is disposed on the first frame guide 511D.

Abstract

L'invention concerne un dispositif de clavier comprenant : un cadre ; des touches qui pivotent chacune autour d'un pivot de touche par rapport au cadre ; un premier guide qui comprend un premier élément relié au cadre ou aux touches, un élément coulissant fixé au premier élément et un second élément qui coulisse avec l'élément coulissant lorsque les touches pivotent par rapport au cadre ; un second guide qui comprend un guide de touche connecté aux touches et un guide de cadre relié au cadre de façon à coulisser avec le guide de touche et qui est disposé en dessous du premier guide ; un troisième guide qui régule, au niveau d'une position derrière les premier et second guides, le mouvement des touches dans la direction d'échelle, l'élément coulissant étant plus souple que le premier élément ou le second élément, et les trois positions du pivot de touche, du premier guide et du second guide, ou les trois positions des premier, deuxième et troisième guides étant disposées de façon à ne pas être alignées dans la même ligne droite lorsqu'elles sont vues depuis une direction dans laquelle les touches sont adjacentes l'une à l'autre.
