Input device and electronic apparatus
View Patent ↗The present invention provides an input device capable of providing a satisfactory operational feeling while achieving a simple structure and a reduced thickness of the device, and an electronic apparatus provided with the input device. The input device includes a touchpad having a sensor plate, which functions as a sensor capable of detecting a touch operation on an operation surface, an actuator driven when a touch operation is detected by the sensor plate, and a vibration generation part on the rear surface of the touchpad, and which generates a vibration by being pressed by the driven actuator and applies the vibration to the touchpad.
1. An input device, comprising:
a touch operation unit which has a sensor that can detect a touch operation on an operation surface;
an actuator that is driven when the touch operation is detected by the sensor; and
a metal dome switch on a rear surface of the touch operation unit, and which generates a vibration by being pressed by the driven actuator, and applies the vibration to the touch operation unit, wherein
the actuator is a solenoid which moves a plunger to press the metal dome switch when the solenoid is energized, the plunger having an upward sloping surface at a distal end, and
the plunger is movable in a direction parallel to the rear surface of the touch operation unit, whereby the upward sloping surface can contact the dome switch and then a non-sloping surface of the plunger can contact the dome switch, whereby the plunger compresses the metal dome switch towards the rear surface of the touch operation unit.
2. The input device according to claim 1 ,
wherein the touch operation unit is a touchpad or a button switch.
3. An electronic apparatus comprising:
an input device having:
a touch operation unit which has a sensor that can detect a touch operation on an operation surface;
an actuator that is driven when the touch operation is detected by the sensor;
a metal dome switch on a rear surface of the touch operation unit, and which generates a vibration by being pressed by the driven actuator, and applies the vibration to the touch operation unit;
a keyboard device; and
a display device which performs display based on an input operation performed through the input device and the keyboard device, wherein
the actuator is a solenoid which moves a plunger to press the metal dome switch when the solenoid is energized, the plunger having an upward sloping surface at a distal end, and
the plunger is movable in a direction parallel to the rear surface of the touch operation unit so as to press the metal dome switch by the upward sloping surface from a side.
