The first and second elastic members are arranged to enable the pressing force applied serially.

Operation apparatus

An operation apparatus includes: an operation plate having an operation surface performed by a pressing operation with an operation body; a vibrator including a movable yoke and a fixed yoke for generating a magnetic circuit for guiding a magnetic flux, and an exciting coil for generating the magnetic flux, and the vibrator vibrating the operation plate through a magnetic force generated by an electrical conduction on the exciting coil; a detector detecting a pressing amount by the pressing operation; a press determinator determining based on the pressing amount detected by the detector whether the pressing operation is performed; and a vibration controller for an electrical conduction on the exciting coil when the press determinator determines that the pressing operation is performed. The detector detects the pressing amount by detecting a change in an electrostatic capacitance generated between the movable yoke and the fixed yoke.

An input device includes: an input unit; a supporting unit supporting the input unit; a first actuator; a second actuator; and a magnetic path forming body forming a magnetic circuit that guides a magnetic flux generated by a first magnetic pole forming unit to pass through a second coil and that also guides a magnetic flux generated by a second magnetic pole forming unit to pass through a first coil. A magnetic resistance to be a resistance in the magnetic circuit is disposed at a middle location along a first connection part that connects an end of a first coil side part to an end of a second coil side part, and a second connection part that connects the other end of the first coil side part to the other end of the second coil side part.

An input device includes: an input portion; a supporting portion supporting the input portion; a first actuator having a first magnetic pole forming portion and a first coil; a second actuator having a second magnetic pole forming portion and a second coil; and a fixed yoke and a movable yoke forming a magnetic circuit for magnetic fluxes generated by the first and second magnetic pole forming portions. One of the fixed yoke and the movable yoke has a magnetic resistance as resistance in the magnetic circuit. A stabilizing force is generated in the movable yoke to stabilize the magnetic circuit against the magnetic resistance. The magnetic resistance is located such that an acting direction of the stabilizing force is opposite to a fall direction of the movable yoke due to own weight in accordance with an inclined installation.

Input device including a stabilizing force

A sliding portion of a slider slides on a sliding surface of a base. This slider is biased toward the base by a stabilizer formed by an elastic, small-diameter, rod-shaped member. Specifically, the stabilizer is formed by a center portion, a link portion, a spring portion, and an abutting portion. When the abutting portion abuts an abutting recess of a cover attached over the slider to be biased toward the base, the spring portion plastically deforms about an arc portion. Due to a resulting reaction force, a pressing portion formed by the center portion biases the sliding portion of the slider toward the base. Accordingly, play may be suppressed with a small number of components.

The manipulation device includes: a fixing portion having a fixing surface to be fixed on an object; a moving part that has a moving surface arranged to face the fixing surface and is configured such that the relative position of the moving surface with respect to the fixing surface is manually adjusted; a fixing portion side circuit component that is arranged at the fixing portion; a moving portion side circuit component that is arranged at the moving portion so as not to be in contact with the fixing portion side circuit component, and includes an electric circuit where the impedance as measured from the fixing portion side is a predetermined impedance; and an input portion that is arranged at the moving portion manually operable, and changes the impedance of the electric circuit measured from the fixing portion.

Manipulation device

A manipulation apparatus that generates a manipulation reaction force on a manipulation knob by energizing a coil disposed between a coil-side yoke and a magnet. A permanent magnet is disposed on a contact portion for a housing of a knob base on which the manipulation knob is mounted. An electromagnet is disposed on a support portion of the housing that supports the contact portion. The electromagnet is energized to generate a repulsive force between the support portion and the contact portion. This reduces a friction force exerted between the support portion and the contact portion.

An operation device includes: a magnet; a coil; an operation unit; a holding body; a mobile body; and a coil-side yoke. The holding body holds the coil. The mobile body holds the magnet so as to provide a predetermined clearance between the coil and the magnet. The mobile body is in contact with the holding body and movable relatively with respect to the holding body due to the operation force input into the operation unit. The coil-side yoke is disposed on the coil opposite to the magnet so as to lead the magnetic line generated by the magnet to the coil. The coil-side yoke is held by the mobile body so as to be movable with the magnet.
