  • Publication number: 20160343361
    Abstract: An actuator includes a movable member that, when moving, abuts against a key (performance operator) to move the key. A first sensor detects motion of the key. A second sensor detects motion of the movable member. A processor determines, based on outputs of the sensors, whether or not the key and the movable member are currently in a mutually separated state. When the key and the movable member are in the mutually separated state, the processor controls the actuator in such a manner that the key and the movable member are in contact with each other. When the key and the movable member are not in the mutually separated state, the processor controls the actuator by use of feedback information based on the output of the first sensor, whereas, in the mutually separated state, the actuator is controlled by feedback information based on at least the second sensor output.

  • Patent number: 9494899
    Abstract: A heater used for a fixing device includes a substrate, first and second conductor patterns formed at either end of the substrate in the short direction of the substrate, a third conductor pattern formed between the first and second conductor patterns and separated from the two conductor patterns, a first heating member disposed between the first and third conductor patterns and electrically connected to the two conductor patterns, and a second heating member disposed between the second and third conductor patterns and electrically connected to the conductor patterns. The heater has both end regions in which the widths of the third conductor pattern in the short direction is smaller than that of a middle portion of the third conductor pattern. The widths of the first and second heating members in the end regions are smaller than the widths of the first and second heating members in the other region, respectively.

  • Patent number: 9384720
    Abstract: Dampers provided in corresponding relation to a plurality of keys are each controlled in response to both an operation of a pedal and an operation of the corresponding key. One half region or half point is determined based on a plurality of half pedal regions or half pedal points, in a stroke of the pedal, specific to the individual dampers. Performance data instructing a pedal operation is generated and recorded on the basis of a stroke position detected in response to a pedal operation and the determined one half region or half point. For each of the keys, a key-damper half region or key-damper half point in a stroke of the key is identified in advance. Performance data instructing key operations is generated and recorded on the basis of the key-damper half regions or key-damper half points specific to the keys and stroke positions detected in response to key operations.
