摘要:
A position indicator is provided which makes it possible for a position detection apparatus to detect a writing pressure or the like from which an influence of a peripheral environment such as a peripheral metal piece is removed while compatibility with a conventional position detection apparatus is taken into consideration. The position indicator includes a first resonance circuit configured including an inductance element and a capacitance element, a second resonance circuit configured including the first resonance circuit and a variation element for varying an electrical element value which varies a resonance frequency or a phase relating to an act of a user, and a switch circuit configured to perform changeover between the first resonance circuit and the second resonance circuit. The switch circuit is changed over such that, when a signal is not received from the outside and when a signal other than a predetermined signal is received from the outside, the second resonance circuit is selected, but when the predetermined signal is received from the outside, the first resonance circuit is selected, as the resonance circuit for electromagnetic coupling to a conductor of a sensor of the position detection apparatus.

The invention refers to an x-y coordinate reader designed to read the movement in two directions on a control surface, where the control surface has a closed belt which can rotate in a first direction and is arranged to be able to move in a second direction. The belt consists of a chain which does not have a tendency to strive for any particular preferred position. In one design that chain (1) consists of adjacent mounted link rods (2), where each link rod is pivotally connected to two adjacent link rods so that the link rods form a closed loop. Typically each link rod (2) is pivotally connected to two adjacent link rods with links (3). That chain can be wound around a carriage (6) which moves on a rail (7). The invention thereto refers to such an x-y coordinate reader which comprises an optical motion sensor (10) which detects the belt's (1) movement, where the optical motion sensor mainly is directed downwards.

Provided is an in-car operation display device which improves the operability of a display unit. The display unit is used for indications and operations for car-installed functions such as settings and instructions of the car-installed functions. An operating means (first switch plate SpL, second switch plate SpR) includes an operating-plate portion (6L, 6R) configured to be operated to move along a display screen 5a of a display unit 5. The operating-plate portion (6L, 6R) includes a protruding switch portion (touch-sensor protrusion 10-15).

A pointing device capable of generating a fixed control signal regardless of operated directions and preventing the generation of a control signal owing to malfunctions, and an electronic apparatus capable of moving a controlled object on a display screen in any direction at a velocity corresponding to an operated amount of an operating section. An original point is defined as a point where a slid distance of a slide key is 0. The maximum slid distance and the minimum slid distance are defined as max _max and min _max, respectively, when moving the slide key until it reaches the rim of an opening section. When the slide key is located within a circular area whose center is the original point and whose radius is n/N of max _max (n and N are arbitrary positive integers, and n
