Abstract
An input device includes an operation portion, a holding portion, a detection portion and at least a switch. The holding portion holds the operation portion so that the operation portion is rotatable around a given axis. The detection portion detects a rotational position of the operation portion with respect to the holding portion. A condition of the switch changes according to an external force exerted to the operation portion.
Claims18
An input device comprising:
- an operation portion;
- a holding portion that holds the operation portion so that the operation portion is rotatable around a given axis;
- a detection portion that detects a rotational position of the operation portion with respect to the holding portion and comprising a bar shaped resistor that can be substantially traversed by a contact as rotation occurs;
- and
- at least a switch of which condition changes according to an external force exerted on the operation portion.
An input device comprising:
- an operation portion;
- a holding portion that holds the operation portion so that the operation portion is rotatable around a given axis;
- and
- a detection portion that detects a rotational position of the operation portion with respect to the holding portion and comprising a bar shaped resistor that can be substantially traversed by a contact as rotation occurs,
- wherein at least a part of the detection portion is provided on a facing surface of the operation portion and on a facing surface of the holding portion,
- the facing surfaces facing to each other.
An electronics device comprising:
- an operation portion;
- a holding portion that holds the operation portion so that the operation portion is rotatable around a given axis;
- and
- a detection portion that detects a rotational position of the operation portion with respect to the holding portion and comprising a bar shaped resistor that can be substantially traversed by a contact as rotation occurs,
- wherein at least a part of the detection portion is provided on a facing surface of the operation portion and on a facing surface of the holding portion,
- the facing surfaces facing to each other.
An input device, comprising:
- a first disk having formed thereon a bar shaped resistor;
- and
- a second disk facing the first disk and having formed thereon patterned conductors for contacting the bar shaped resistor that can be substantially traversed by a contact and producing an output resistance that varies as the first and second disks rotate with respect to each other.
