摘要： A hammer device for an electronic keyboard instrument, enabling prevention of grease or the like from adhering to an actuator portion during mounting of the hammer, to thereby enable speedy hammer mounting work and improve the work efficiency. The hammer device includes a hammer support and hammers arranged side by side in a left-right direction and each pivotally supported by the hammer support to pivotally move in accordance with depression of an associated key. When mounting the hammer to the hammer support, before a shaft hole is engaged with a fulcrum shaft portion, left and right protrusions of the hammer are brought into abutment with respective left and right stopper walls provided close to the respective left and right ends of the fulcrum shaft portion, to thereby prevent the actuator portion from being brought into contact with the fulcrum shaft portion.

摘要： A key switch for an electronic piano, which makes it possible to increase an allowable range for shift of a movable contact without increasing the size of the key switch of the three-contact type. The key switch includes a substrate having first to third stationary contacts arranged thereon side by side in the lengthwise direction of a pivotal member as one of a key and a hammer. Each stationary contact has a common contact and a non-common contact. The common contact has an extended portion extending between two non-common contacts. The key switch has first to third movable contacts arranged side by side on an elastic switch body, for being sequentially brought into contact with the common contacts and non-common contacts of the stationary contacts as the switch body is pressed by the pivotal member, to thereby output signals indicative of key depression information.

摘要： 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.
