Input device

Abstract

An input device (ID) comprises: a housing (HS); a movable member (MB) which is at least partially stored in the housing (HS) and is supported in the housing (HS) so as to be able to reciprocate in the Z-axis direction; soft magnetic members (1M) fixed to the housing (HS); and a magnet (5) fixed to the movable member (MB) so as to face the soft magnetic members (1M) in the Y-axis direction. The soft magnetic members (1M) have strong attraction portions (11) which are portions having a relatively strong magnetic attraction force between the magnet (5) and the soft magnetic members (1M), and weak attraction portions (10) which are portions having a relatively weak magnetic attraction force between the magnet (5) and the soft magnetic members (1M). The strong attraction portions (11) are disposed such that one ends thereof are positioned at the inner side of one ends of the magnet (5) in the Z-axis direction. The weak attraction portions (10) include portions that extend outward from the one ends of the strong attraction portions (11) in the Z-axis direction.

Claims

1. A stationary member and A movable member is provided, at least a portion of which is housed inside the stationary member and which is supported by the stationary member so as to be able to reciprocate along a first direction. A soft magnetic member fixed to the aforementioned stationary member, An input device capable of applying an operating reaction force, comprising: a magnetic field generating member fixed to the movable member so as to face the soft magnetic member in a second direction perpendicular to the first direction; The soft magnetic member has a strong attractive portion, which is a portion where the magnetic attractive force between the magnetic field generating member and the soft magnetic member is relatively strong, and a weak attractive portion, which is a portion where the magnetic attractive force between the magnetic field generating member and the soft magnetic member is relatively weak. The strong suction portion is arranged such that, in the first direction, one end is located inward from one end of the magnetic field generating member. The weak suction portion includes a portion that extends outward from one end of the strong suction portion in the first direction. One end of the weak suction portion is located outside the one end of the magnetic field generating member, even when the movable member moves in one direction in the first direction. An input device characterized by the following features.

2. The strong suction portion is arranged such that, in the first direction, its other end is located inward from the other end of the magnetic field generating member. The weak suction portion includes a portion that extends outward from the other end of the strong suction portion in the first direction. The other end of the weak suction portion is located outside the other end of the magnetic field generating member, even when the movable member moves in the other direction in the first direction. The input device according to claim 1.

3. In the second direction, the distance between the strong attraction portion and the magnetic field generating member is smaller than the distance between the weak attraction portion and the magnetic field generating member. The input device according to claim 1.

4. The magnetic field generating member includes a first magnet and a second magnet arranged along the first direction, The strong suction portion includes a first strong suction portion corresponding to the first magnet and a second strong suction portion corresponding to the second magnet. The weak suction portion includes a portion extending between the first strong suction portion and the second strong suction portion. The input device according to claim 1.

5. In the second direction, the thickness dimension of the weak suction portion is smaller than the thickness dimension of the strong suction portion. The input device according to claim 1.

6. The weak suction portion is formed integrally with the strong suction portion. The input device according to claim 1.
