Abstract: An input device includes: an inputter to which an operation is input by a user; a frame that holds the inputter and moves in a first direction in response to the operation input by the user; a substrate disposed on a side to which the frame moves in the first direction; a first elastic body disposed between the frame and the substrate; a load sensor that detects a load applied to the inputter, based on the movement of the frame in the first direction; a restrictor that restricts the movement of the frame in a second direction that is opposite to the first direction; and a second elastic body disposed between the restrictor and the movable portion. The second elastic body has a repulsion elasticity lower than a repulsion elasticity of the first elastic body.

Abstract: A display device includes: a front cover that is optically transmissive; a design sheet that is optically transmissive and is arranged on the front surface side or the back surface side of the front cover; a cushion layer that is optically transmissive and is arranged on the back surface side of the front cover; and a light source that is arranged on the back surface side of the cushion layer. The cushion layer includes a plurality of first recessed portions each of which is, in a cross-sectional view taken along a plane parallel to a stacking direction of the front cover and the design sheet, in a projecting shape in the stacking direction and is in a recessed shape on the back side of the projecting shape.

Abstract: A display device including (i) a light source and (ii) a light guide body which guides light emitted by the light source, and includes: a light guide leg that guides the light entering through a light entrance surface; and a light exit portion connected to the light guide leg and including a reflection design portion which reflects, in a first direction, a portion of the light guided by the light guide leg and another reflection design portion which reflects, in the first direction, another portion of the light. When viewed in the first direction, the reflection design portion is disposed in a first region on a second direction side with respect to a connecting portion of the light exit portion connected to the light guide leg, and the other reflection design portion is disposed in a second region on a third direction side with respect to the connecting portion.

Abstract: An input device includes: a panel on which a pressing operation is performed by an operating body; a substrate provided on a back surface side of the panel; a first electrode provided on the substrate; a holder that is provided on a back surface side of the substrate, includes a second electrode at a part facing the first electrode, and engages with the panel; a push-in detector that detects electrostatic capacity between the first electrode and the second electrode; and a vibration device held by the holder. The holder moves relative to the substrate when the pressing operation is performed on the panel, has rigidity and conductivity, and covers the second electrode from its back surface side.

Abstract: A display device includes: an outer cover with light transmission properties; a design sheet with light transmission properties provided on the outer cover; a cushion layer with light transmission properties provided on a back surface side of the outer cover; and a light source provided on a back surface side of the cushion layer. When viewed in a cross section, the cushion layer includes: a plurality of first concave portions that are in a convex shape in a first orientation and a concave shape on a side opposite to the convex shape; and a plurality of second concave portions that are connected to the first concave portions and are in a convex shape in a second orientation and a concave shape on a side opposite to the convex shape. The first concave portions and the second concave portions are alternately provided.
