Abstract: A lens actuator includes a carrier that is configured to retain a lens; a first AF coil that is disposed in the carrier while wound about an axis perpendicular to a lens retaining surface; first to fourth magnets that are disposed opposite the first AF coil in four directions parallel to the lens retaining surface; a first OIS coil that is disposed opposite the first magnet; and a second OIS coil that is disposed opposite the second magnet. A current is passed through the first AF coil to move the carrier in a vertical direction along an axis. The currents are passed through the first and second OIS coils to a movable unit in front-back and left-right directions. Therefore, weight reduction of the movable unit can be achieved to provide a lens actuator, in which electric power saving can be achieved.

Abstract: An input device includes an input detection portion which enables detection of position inputs according to change of capacitance; a position detection portion which reads detection signals from the input detection portion and detects positions thereof; a light emitting portion placed near the input detecting portion; driving portion which drives the light emitting portion; a monitoring portion which monitors a driving voltage applied from the driving portion to the light emitting portion; and a control portion which controls a generation of pulse signals at times when the position detection portion reads the position inputs from the input detection portion, the generation of the times being based on the driving voltage monitored by the monitoring portion.

Abstract: The main body of the actuator structure is generally formed into a “pitchfork”shape. The middle bar of the pitchfork forms a Y-bend at its forward end. The Y-bend is disposed so that each tip of the bend is adjacent to the outer bar on each side of the pitchfork. At least a coil is fixed on each bar of the main body. The forward ends of the Y-bend abut against a movable member. In the structure above, applying a current to a coil generates minute movements in each tip of the Y-bend, thereby moving the movable member.

Abstract: Provided is a remote controller in which a ring-shaped operating part is structured rotatable and capable of making rocking motion by pressing, a first remote-control signal responsive to rotation of the operating part allows sound volume adjustment, a second remote-control signal responsive to a switch signal supplied by pressing the operating part changes the function to channel selection, a third remote-control signal responsive to rotation of the operating part within a predetermined period of time allows channel selection. This structure can reduce the number of separate operating keys and allows a simple successive operation of the operating part to control a receiver.

Abstract: There is provided a user interface with which a greater number of processes are executable in response to user operations made to a directional input device. When the directional input device receives a first direction followed by a second direction within a predetermined time period, the amount of change from the first direction to the second direction is calculated. If the calculated change amount exceeds a predetermined range, a first processes associated with each of the first and second directions is performed. If the calculated change amount falls within the predetermined range, a second process associated with the change amount is performed.
