Input device and information processing apparatus

摘要

An input device includes: a main body portion having one surface; a movable portion having a contact surface formed in the one surface of the main body portion, is operated through the contact surface and is movable relative to the main body portion; a supporting portion that is provided in the main body portion and movably supports the movable portion; an applying portion that applies a force to move the movable portion; a determining unit that detects whether there is a contact with the contact surface of the movable portion and determines a state-of-contact whether the contact surface is in contact state or in non-contact state; a controller that controls the applying portion to move the movable portion to a predetermined position when the determined state-of-contact changes from contact state to non-contact state; and an output unit that detects and outputs the amount of movement of the movable portion relative to the main body portion while the determined state-of-contact, and does not output the amount of movement when the controller moves the movable portion.

1. An input device comprising:
a main body portion that has one surface; a movable portion that has a contact surface formed in the one surface of the main body portion, is operated through the contact surface and is movable relative to the main body portion; a supporting portion that is provided in the main body portion and movably supports the movable portion; an applying portion that comprises a plurality of magnets and a plurality of coils and applies a force to move the movable portion; a determining unit that comprises a contact sensor that detects a contact with the contact surface of the movable portion, the determining unit determining a state-of-contact whether the contact surface is in a contact state or in a non-contact state based on an output of the contact sensor; a controller that controls an amount of current flowing through each coil of the applying portion and the flow direction of current to move the movable portion using a driving mechanism to a predetermined position when the state-of-contact determined by the determining unit changes from the contact state to the non-contact state; and an output unit that detects and outputs an amount of movement of the movable portion relative to the main body portion while the state-of-contact determined by the determining unit is in contact state, and does not output the amount of movement when the controller moves the movable portion, wherein the controller sets a magnitude of a magnetic force of each of the magnets and an amount of current flowing through each of the coils such that returning the movable portion is completed within 0.5 seconds after a finger of an operator is taken away from the contact sensor.
