Abstract
A multidirectional input member according to the present invention includes a base plate on which a looped sensor that includes a plurality of groups of non-contacting electrodes configured in a loop is formed and an operation plate locating opposite to the base plate. The operation plate has a first loop-shaped protrusion that is located at a plane opposite to the base plate, that is protruded toward the base plate side, that is opposite to the looped sensor, and that is configured with a resistant rubber member. The first protrusion has a configuration in which its sectional area of a plane parallel to the base plate is tapered in the direction from the operation plate side toward the base plate side.

A multidirectional input member comprising:
- a base plate;
- a looped sensor that includes a plurality of groups of non-contacting electrodes configured in a loop and that is formed on the base plate;
- and
- an operation plate located opposite to the base plate, wherein
- the operation plate has a first loop-shaped protrusion that is located at a plane opposite to the base plate, that is protruded toward the base plate side, that is opposite to the looped sensor, and that is configured with a resistant rubber member,
- the first protrusion has a configuration in which its sectional area of a plane parallel to the base plate is tapered in the direction from the operation plate side toward the base plate side,
- the base plate has at least one group of non-contacting electrodes at an inside region of the looped sensor, and
- the operation plate has a conducting second protrusion at a location that contacts the at least one group of electrodes in a plane opposite to the base plate.
An electrical device comprising:
- a multidirectional input member that has a base plate, a looped sensor in which a plurality of groups of non-contacting electrodes configured in a loop and that is formed on the base plate, and an operation plate located opposite to the base plate, wherein
- the operation plate has a first loop-shaped protrusion that is located at a plane opposite to the base plate, that is protruded toward the base plate side, that is opposite to the looped sensor, and that is configured with a resistant rubber member, and
- the first protrusion has a configuration in which its sectional area of a plane parallel to the base plate is tapered in the direction from the operation plate side toward the base plate side;
- and
- a control unit that is configured to specify a pressing location of the first protrusion based on electrical resistance of each of the groups of the electrodes that is changed by contact between the first protrusion and the plurality of groups of electrodes and a voltage value or current value that varies by the electrical resistance, wherein
- the base plate has at least one group of non-contacting electrodes at an inside region of the looped sensor,
- the operation plate has a conducting second protrusion at a location that contacts the at least one group of electrodes in a plane opposite to the base plate, and
- the control unit detects input of a switch by contacting between the second protrusion and the at least one group of electrodes.
