Key switching device and keyboard device

Abstract

The present invention provides a key device and a keyboard device. Key device ( 1 ) comprises: substrate ( 2 ); the first controlling lever portion (3) engaged on the substrate being able to slide freely; the second controlling lever portion (5), fixing portion (6) engaged and supported by said controlling lever potions (3), (5); chain shield (10); and switching component (9) provided between said substrate (2) and said fixing portion (6), wherein rotating shafts (3d), (3f) of said the first controlling lever portion are arranged perpendicularly with rotating shafts (5c), (5d) of said second controlling lever portion. This device of the invention is the key switching device and the keyboard device with the switching device, which can be minimized in shape and thinned in dimension, its contact portions being able to be contacted reliably to perform the key inputting even though only the surrounding portions on the key top portions are pressed with fingers.

Description

technical field [0001] The present invention relates to a key switch device with good performance, which is used in a keyboard device or an input switch device used in input and output devices such as word processors and personal computers, and a keyboard device provided with the key switch device. Background technique [0002] according to Figure 4 , Figure 5 A conventional X-type key switch device applied to a keyboard device will be described. The mounting member 31 made of a metal plate or the like has: a bottom wall 31a; cut off from the bottom wall 31a in a double-supported state, a plurality of relatively long support portions 31b formed in an orderly arrangement; and cut off from the bottom wall 31a in a cantilever state. , A plurality of semicircular-arc-shaped fixing portions 31c formed in a pair with the above-mentioned supporting portion 31b. Also, a flexible substrate (not shown) provided with a plurality of fixed contacts 32 is arranged on the upper surface...

Problems solved by technology

But when Figure 4 , Figure 5 In the key switch device of the structure shown, since the rotation shaft 34d as the rotation center of the lever members 34, 35 is located at the longitudinal center of the lever members 34, 35, the rotation axis 34d is the center of the lever members 34, 35. The upper end side of the key switch is connected to the key top 36, and the lower end side of the lever parts 34, 35 is connected to the mounting part 31 side. With the aim of miniaturization and thinning of the key switch device, when the lever parts 34, 35 are shortened However, the control rod members 34, 35 have a limit length that can rotate smoothly, and there is a disadvantage that they cannot be further miniaturized and thinned.
