A sensor apparatus and an information processing apparatus having excellent operability are provided. A sensor apparatus includes a touch panel, a casing, and a pressure-sensitive sensor. The touch panel includes an input operation surface and detects a position at which an operator comes into contact with the input operation surface directly or indirectly. The casing accommodates the touch panel. The pressure-sensitive sensor includes a first electrode fixed to the touch panel, a second electrode fixed to the casing, and an elastic body arranged between the touch panel and the casing and elastically supporting the touch panel with respect to the casing. The pressure-sensitive sensor detects a pressing force input to the input operation surface, as a change of a capacitance between the first and second electrodes.

Sensor apparatus and information processing apparatus

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.

A portable type information processing terminal device is provided which includes a substrate carrying a substantially annular antenna coil thereon, a signal processing integrated circuit element arranged inside the antenna coil, a magnetic plate arranged under the substrate and a metal plate arranged under the magnetic plate, which are integrally formed and arranged on one or more than one metal parts including a battery pack. The metal plate is used to substantially regulate the resonance frequency of the antenna coil so that it is allowed to be arranged in a cabinet of the portable device.

Portable type information processing terminal device

A power unit is provided that is not affected by a voltage fluctuation of a reverse flow-preventive diode provided in an output line thereof and that can provide a stable output controlled with a high accuracy. A first rectified diode,rectified and a first smoothing capacitor,smoothes the voltage switched by a transformer,to generate a DC voltage (V,) at an A point. A reverse flow-preventive diode,and an output resistor,are provided between the A point and a positive output terminal,The comparison/detection circuit,compares the anode and cathode potentials of the reverse flow-preventive diode,with each other. The comparison/detection circuit,supplies a differential amplifier,the anode or cathode potential whichever is lower.
