Abstract

The invention relates to a keyboard wind instrument, a single valve type is adopted, a keyboard and a portamento structure are arranged on the frame with a plurality of flute chambers. A plurality of leaf valves which are arranged corresponding to a plurality of keys which forms the keyboard can close the air outlet parts of the corresponding flute chambers at the non-performing time, and the airoutlet parts are opened when performing. The portamento structure can temporarily reduce the pitch of the sound that is made to get the portamento effect and the portamento structure is arranged corresponding to the leaf valves which are positioned abreast, comprising: a valve pressure body, which can rotate flexibly and comprises a rotating shaft and a connection bar; an operation part, which can enable the valve pressure body to rotate towards the direction of the leaf valve; a force application part, which can enable the valve pressure body to regress to the initial position; a limiter, which can limit the rotation angle of the valve pressure body.

Description

technical field

[0001] The present invention relates to a keyboard wind instrument having a bend mechanism for continuously changing the pitch of a sound. Background technique

[0002] Keyboard wind instruments are basically determined by the natural frequency of each reed (reed), so the tone of the sound cannot be continuously changed, and it is an instrument that cannot obtain performance effects such as portamento. Recently, there has been proposed a keyboard wind instrument in which the tone of a sound can be continuously changed by adding a portamento mechanism. One example thereof is disclosed in Japanese Patent Application Laid-Open No. 9-16163 (see paragraphs

[0008] to

[0018] and FIG. 2 ). In addition, with regard to such a keyboard wind instrument having a portamento mechanism, by searching various databases, etc., other than the above-mentioned publications, no prior art documents closely related to the invention of the present application can be found, so the abo...
