Abstract

The present invention provides an electronic keyboard musical instrument having a drive unit for driving keys like an automatic player piano, and whose protruding portion at the lower part of the instrument body does not interfere with the player's feet. The electronic keyboard instrument is provided with a drive unit (2) in an opening (10a) of a bottom plate (10). The hammer structure (13) is driven by the drive unit (2). By arranging the plunger (24F) on the front side and the plunger (24R) on the rear side of the drive unit (2) near the rotation fulcrum (02) of the hammer structure (13), the weight of the plunger (24) can be reduced. high. The drive unit (2) and the drive unit substrate (3) are covered with a drive unit cover (4). An inclined surface (41) is provided on the front side of the drive unit cover (4).

Description

technical field [0001] The present invention relates to an electronic keyboard musical instrument in which keys of a keyboard are driven using automatic performance data, like an automatic player piano. Background technique [0002] In the past, in electric pianos, based on pre-stored performance information (piano action or MIDI data), actuators such as solenoids were used to drive the keys, and the linked hammers were driven to strike the strings to perform automatic performances. For example, the technology disclosed in Japanese Patent Application Laid-Open No. 9-237082 (Patent Document 1). [0003] On the other hand, it is widely known that in an electronic musical instrument having an electronic sound source, performance data (MIDI data) is input from the outside (sequencer), or performance data stored in an external medium is temporarily stored in an internal memory or read. Then, based on the performance data, the electronic sound source is played to perform automati...
