摘要： A vibration actuator includes: a fixing part including one of a coil and a magnet; a movable part including the other one of the coil and the magnet; and an elastic supporting part configured to support the movable part movably with respect to the fixing part. The movable part is configured to reciprocate with respect to the fixing part in a vibration direction through cooperation between the powered coil and the magnet. The magnet is disposed away from and radially inside the coil. The elastic supporting part has a plate-like shape in which one end of the elastic supporting part is fixed to the fixing part at the side of the movable part and the other end is fixed to the movable part, and cantilevers the movable part in such a manner that the movable part can reciprocate in the vibration direction.

摘要： An actuator includes: a movable body including a single-pole magnetized single pole magnet; and a plurality of electromagnets each having a magnetic core portion and a coil portion for exciting the core portion. The actuator has: a fixed body on which three or more magnetic poles of the electromagnets are disposed at positions orthogonal to the magnetization direction of the single-pole magnet; and an elastic body bridged between the movable body and the fixed body and elastically deforming when current is supplied to the coil portion, thereby supporting the movable body so as to be movable in the magnetization direction of the single-pole magnet and the two-degree-of-freedom direction. The elastic body is attached to the movable body so that the movable center of the movable body matches the substantial center of the generated magnetic torque of the movable body.

摘要： A display apparatus includes: a display device; a touch panel for sensing movement of an input object; a storage storing data representating images; and a controller. Images are displayed on the display device so as to be arranged in an arrangement order. The controller calculates a moving amount for moving the images, in response to movement of the input object. When the images are movable by the calculated moving amount in a moving direction commanded, the controller moves the images displayed on the display device, by the calculated moving amount in the moving direction. When the images are not movable in the moving direction by the calculated moving amount, the controller changes a display manner of the images and display the images in the changed display manner.
