Sensor apparatus and electronic apparatus

摘要

A sensor apparatus includes: a display cover including an operation area that is pressed by an operator and a circumferential area located on the circumference of the operation area; a frame including an opening covered by the operation area and a fixing portion that fixes the circumferential area; a touch panel that is supported by the display cover to be positioned at the opening and detects a position at which the operator comes into contact with the operation area; and a pressure-sensitive sensor that is provided between the display cover and the frame, includes a first electrode and a second electrode opposed to the first electrode, and detects a pressing force with respect to the operation area based on a change of a capacitance between the first electrode and the second electrode that corresponds to a deflection amount of the display cover.

1. A sensor apparatus, comprising:
a display cover including an operation area that flexes in response to a pressing force of an operator on the operation area and a circumferential area located on the circumference of the operation area; a frame including an opening covered by the operation area and a fixing portion extending inwardly from an outer portion of the frame and arranged to fix the circumferential area of the display cover, wherein the outer portion of the frame does not support, above the outer portion, the circumferential area of the display cover, wherein a joint of the circumferential area and the fixing portion is configured to act as a fulcrum in response to the pressing force of the operator on the operation area, wherein the fixing portion of the frame is arranged to support above the fixing portion, a pressure-sensitive sensor and the circumferential area of the display cover; a touch panel, which is supported by the display cover, wherein the touch panel is configured to detect a position at which the operator comes into contact with the operation area; and the pressure-sensitive sensor, which is provided between the display cover and the fixing portion of the frame, wherein the pressure-sensitive sensor includes a first electrode, a second electrode opposed to the first electrode, wherein the second electrode is connected to the fixing portion of the frame via an adhesive, and a spacer provided between the display cover and the fixing portion of the frame to create a gap between the first electrode and the second electrode, and wherein the pressure-sensitive sensor is configured to detect a pressing force with respect to the operation area based, at least in part, on a change of a capacitance between the first electrode and the second electrode that corresponds to a deflection amount of the display cover.
