An input device which is capable of imparting a magnetic operational reaction force, includes a stationary member, a magnetic member fixed to the stationary member, a movable member at least partially housed in the stationary member to which the magnetic member is fixed, and a driving device including a magnet fixed to the movable member and coils fixed to the stationary member, configured to move the movable member in a first direction relative to the stationary member, wherein the magnet is magnetized along a second direction perpendicular to the first direction, wherein the coils have bundles of turns constituted by conductive wires, and the conductive wires in the bundles of turns extend along a third direction perpendicular to each of the first direction and the second direction, and the conducting wires are juxtaposed along the first direction.

Input device

An input device includes an operation shaft extending in a first direction, linearly movable in the first direction, and having a tip portion; a force sensation generator configured to apply a force to the operation shaft; a sensor configured to detect an amount of movement of the operation shaft; a range-of-motion adjuster configured to change a maximum push-in position of the operation shaft; and a range-of-motion adjustment motor configured to operate the range-of-motion adjuster. The range-of-motion adjuster has a contact portion with which the tip portion of the operation shaft comes into contact. The range-of-motion adjuster changes the maximum push-in position of the operation shaft by being operated to change a contact position of the tip portion with respect to the contact portion in the first direction.

An input device includes an manipulating part, a movable member fixed to the manipulating part and having a rotating shaft, a fixing member configured to rotatably support the rotating shaft so that the movable member is rotatable, a flex sensor disposed on the manipulating part and configured to detect flexing of the manipulating part, a switch disposed on the movable member or the fixing member, pressed by a rotating operation of the movable member, and configured to switch between an on state and an off state when a flexing amount of the manipulating part reaches a predetermined amount, and a signal processor configured to output a control signal, based on a first output signal of the flex sensor, and a second output signal of the switch.

A torque generation apparatus includes a magnetic disc rotatable about a rotation axis, a first yoke, a second yoke, a magnetic viscous fluid placed between the magnetic disc and the first yoke and the second yoke, a coil, and a third yoke. The coil overlaps with the magnetic disc as viewed along the rotation axis. The third yoke constitutes a magnetic path of a magnetic field generated by the coil together with the first yoke and the second yoke. The magnetic disc includes a torque increasing portion at at least one of a surface facing the first yoke and a surface facing the second yoke. The torque increasing portion is provided in an outer circumferential area of the magnetic disc in a radial direction and causes a shearing force to a cluster of the magnetic viscous fluid to become larger than that in the inner circumferential area.

An organic electroluminescence (EL) device whose organic EL layer is less likely exposed to moisture. The organic EL device includes an organic EL layer; and a hygroscopic layer disposed with respect to at least one main surface of the organic EL layer. The hygroscopic layer includes: a hygroscopic film containing a base material and a hygroscopic agent mixed in the base material; and a pair of covering films each covering a different one of surfaces of the hygroscopic film in a thickness direction of the hygroscopic film. A region of the hygroscopic film that is in contact with one covering film whose distance from the organic EL layer is smaller than a distance of the other covering film from the organic EL layer contains the hygroscopic agent at a content rate lower than an average content rate of the hygroscopic agent in the hygroscopic film.

Organic EL device

An organic EL device includes: an organic EL layer; and a hygroscopic layer that is disposed above and/or below the organic EL layer, and has a hygroscopic film, a first covering film, and a second covering film, the first covering film covering one of main surfaces of the hygroscopic film, the second covering film covering the other main surface of the hygroscopic film, wherein a relational expression A/B&#x2267;0.2 is satisfied, where A denotes hygroscopicity indicating mass of moisture, expressed in g/m, that is absorbable by the hygroscopic film per unit of area, and B denotes the number of defects per unit of area, expressed in pieces/mm, that is calculated based on the number of defects in each of the first covering film and the second covering film.
