Abstract

A key structure which has a key formed by a wood part so as to present a woody appearance and which makes it possible to prevent support members thereof that support the wood part from being damaged during machining of the wood part for width adjustment. The key structure functions as a key pivotally moved by key depression when it is mounted in a keyboard apparatus. A wood part includes a narrow part having opposite lateral sides. An elongated upper plate body has opposite lateral sides, and fixedly supports the wood part. Recessed parts are formed in the respective lateral sides of the upper plate body at least in a substantial entirety of a region of the upper plate body in a longitudinal direction of the key structure where the wood part does not exist. The recessed parts are recessed laterally inward of the respective lateral sides of the narrow part of the wood part.

Description

technical field [0001] The present invention relates to a key structure applied to a key having a wood part; and a keyboard device including the key structure. Background technique [0002] In general, a key structure is known, which pivotally moves as a key by pressing the key, and which uses wood or the like, as disclosed in Japanese Utility Model Publication No. 2514485 and Publication (Kokai) No. 2903959 Japanese published patent. In this wooden key structure, wooden material is used at least for the so-called "visible part", which is visible from the outside during playing and non-playing, the key structure has a wooden appearance and thus a high quality Exterior. [0003] In the wooden key structure, the wooden part is supported and fixed, for example, bonded with an adhesive to the lower surface of the upper plate having the pressing surface, or to the upper surface of the key base as the lower plate. The supports such as the upper plate and the key base have an el...
