IPC: G01B7/00
Filed: 1993-09-28
Abstract: PURPOSE:To realize accurate position detection by providing two sets of resistors that are respectively provided with a sliding constitution thereon at a specified interval that can be slid by a slider and by shifting respective port positions to detect a signal from the part in between. CONSTITUTION:Registors 2 and 2-1 are parallely arranged and the port positions 21-2n and 41-4n thereof for picking-up signals are made alternate to each other, thereby picking up the signals in such a manner by shifting the port positions. That is, two sliders 3 and 3-1 are moved integrally, however, the signal pick-up position selects the output signal on a resistor side which is one the central position of a port. For example, when the sliders 3 and 3-1 are placed near the output port F, the output of the port F is dull, so it may not be used. Instead, the position X is calculated by using the output ports B and C on the resistor 2. In other words, a linear part having least differences is outputted so as to calculate the position.
