Keyboard device for electronic keyboard instrument and mounting structure of let-off imparting member for electronic keyboard instrument

Abstract

A keyboard device for an electronic keyboard instrument, which enables facilitation of work for mounting and dismounting a key switch and install hammers and the key switch with high accuracy, and provision of a touch feeling similar to one provided by an acoustic grand piano while keeping the device compact in depth. The device comprises swingable keys, a hammer support formed by a synthetic resin molded article, hammers pivotally supported by the hammer support, and a key switch including switch bodies provided in association with the hammers and a switch board. The hammer support has a switch mounting part formed with an opening vertically extending therethrough. The key switch is removably mounted to the switch mounting part, with the switch bodies facing the hammers from above via the opening and the switch board placed on the upper surface of the switch mounting part.

Description

technical field [0001] The present invention relates to a keyboard device applied to an electronic keyboard musical instrument such as an electronic piano and a mounting structure of a release transmitting member for delivering a let-off feeling very similar to that provided by an acoustic piano. Background technique [0002] In general, as a keyboard device for an electronic piano, there has been known, for example, a keyboard device disclosed in Japanese Laid-Open Patent Publication (Kokai) No. 2010-262129 filed by the assignee of the present application. The keyboard device includes a plurality of swingable keys, a plurality of hammers arranged to be associated with respective keys and each configured to pivotally move in accordance with depression of the associated key, and a key for detecting key depression on the key. Information key switch. Each of the keys is swingably supported by a balance pin erected through a balance pin hole formed in a central portion of the k...

AI Technical Summary

Problems solved by technology

However, in the conventional keyboard device, as described above, since the release member is mounted to the action chassis through the clamps fixed to the action chassis with screws, the release member sometimes cannot be used with respect to the corresponding hammer directly mounted to the action chassis. accurately locate

In addition, when the posture or position of the distal end between the release members changes, there is a concern that the release feeling may not be uniformly and stably transmitted to all the keys during key depression

Therefore, the above-mentioned keyboard device also has room for improvement in terms of the installation structure of the release member.
