The present invention provides a trackball and an in-vehicle device controller using the trackball. The trackball provides a stable operational feel and is easy to operate even in an environment in a vehicle where vibration and movement are present. The trackball includes a ball made of a non-magnetic material and having embedded therein bar members made of a magnetic material and arranged on three axes orthogonal to one another, a case enclosing the ball such that at least an upper portion of the ball is exposed, magnetic members fixed to the case on two axes penetrating through the center of the ball and orthogonal to each other so as to allow magnetic coupling to ends of the bar members, and another magnetic member fixed to the case on an axis penetrating through the center of the ball and orthogonal to the two axes so as to allow magnetic coupling to an end of one of the bar members.

A lens actuator has a carrier, a cover, a first spring, a second spring, a coil, and a magnet. The carrier with a cylindrical shape is provided with a hollow section formed along a first direction, and has a holding section formed on one side of the first direction. The hollow section has a shape configured to mount a lens barrel therein. The cover, which is disposed on the side having the holding section of the carrier, has a supporting section that meets with the holding section of the carrier. The first spring and the second spring make a resilient contact with each of both surfaces in the first direction of the carrier. The coil is circumferentially disposed on the carrier so as to face the magnet. Of the coil and the magnet, one is mounted on the carrier and the other is disposed on the outer or the inner periphery of the carrier.

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.

A method for controlling an input portion of electronic devices enables the input portion capable of both a coordinate input operation and a pressure input operation to be easy-to-use. The input portion, which includes an operation panel, a coordinate input section disposed thereunder, and a pressure input section disposed thereunder, is connected to a controller so as to form an input device. In the coordinate input operation, the user runs a finger across the operation panel, and in the pressure input operation, the user presses a predetermined position. In the method, the distinction between the two input operations is performed by detecting the shape of the contact part of the finger in contact with the surface of the input portion based on the signal obtained from the coordinate input section and by using the detected result and predetermined criteria. The controller outputs the signal corresponding to the determination.

An input device includes an input section formed of a display sheet and a coordinate input sheet, and a switch section allowing a push-input and placed on a substrate at a place corresponding to a display section of the display sheet. A foamed layer containing air and working as an insulating resin layer is placed between the input section and the substrate. The input section is supported via the foamed layer.

An optical trackball device of the present invention includes a ball as an operating member, using a material that partially transmits light, and this ball is rotatably supported by a support member. Light emitted from a light emitter disposed beneath the ball is reflected on this ball. A detector detects the reflected light to identify rotation of the ball. Since the light from the light emitter is partially transmitted through the ball, the ball can be illuminated without providing an additional component. Accordingly, a location of the ball is easily recognizable even in a dark place.

A lens actuator is provided for moving a movable part including a lens, with respect to a fixed part in the optical axis direction of the lens. The lens actuator includes (a) a magnet disposed on the surface of the movable part facing the fixed part and magnetized in the optical axis direction, (b) a coil disposed on the surface of the fixed part facing the magnet, and (c) a pair of magnetic materials disposed on both sides of the magnet in the optical axis direction, to direct magnetic flux from the magnet toward the coil.

A trackball device including (i) a sphere, (ii) a support for rotatably supporting the sphere, (iii) a rotation detector for detecting rotation of the sphere, and (iv) a controller. The controller generates a specific output signal responsive to a signal from the rotation detector. The trackball device further includes an informer for generating auxiliary information that gives feedback of the situation to an operator according to how the sphere rotates. This structure can provide a trackball device having excellent user-friendliness. Because this trackball device gives feedback of the position of a pointer on a display to the operator, the operator doesn't have to look at the display. Thus, this trackball device is especially preferred for incorporation into a vehicle.
