摘要： A keyboard apparatus has a plurality of elastically deformable elastic members disposed on a board in a predetermined positional relationship, a plurality of push members each disposed above each of said plurality of elastic members and adapted to push said elastic member to cause the same to elastically deform and produce an acoustic signal. At least three pickups are disposed on the board at different positions for sensing arrival of the acoustic signal. A detecting circuit determines for detecting the keyed position in response to the output from each of the pickups based upon the differences between arrival times of the acoustic signal at these pickups.

摘要： An automatic tooling machine includes a spindle carrier having a spindle for supporting a machining tool. The spindle carrier includes a tool drum mounting device for rotatably supporting a tool drum having plural machining tools thereon. A device is provided for transferring a selected machining tool between the tool drum supported on the tool drum mounting device and the spindle. A drum storage rack is fixedly positioned separate from the spindle carrier and extends in a longitudinal direction. The rack includes a plurality of drum support members for storing a plurality of tool drums. A carriage track is integral with the spindle carrier. A device is provided for selectively moving the spindle carrier to a position such that the carriage track is positioned adjacent and aligned with a selected of the drum support members. A carriage is provided for moving the tool drum of the selected drum support member along the carriage track between the tool drum mounting device and the selected drum support member. A servo-motor and worm gear arrangement is provided for rotating the tool drum on the tool drum mounting device.
