Title:
CAPACITY-ORIENTED INDICATOR FOR POSITION
Document Type and Number:
Japanese Patent JPS5749810
Kind Code:
A
Abstract:
A capacitive indicator of position, comprises an oscillator (41) operating within the frequency and with the wave shape selected for the operation of the device, transmitter strips (11, 12) of a length of the desired distance of indication of the movement and formed, e.g., in the way of printed circuits as connected to the said oscillator (41) as well as corresponding receiver strips (21, 22, 31, 32) as connected to a differential amplifier, (42) e.g. to the amplifier of an integrated circuit. Hereinafter it is possible, by means of the indicator, (43) to indicate a connecting together of the transmitter strips and the receiver strips by means of mobile plates (14, 15) placed on the device whose position is supposed to be indicated. According to the invention, the transmitter strips (11) and the receiver strips (21) are formed in such a way in pairs tnat the mobile plates (14) when placed on one side of the indication point, (16) connect a certain one of the transmitter strips (11) with a certain one of the receiver strips (21) but, after the mobile plates (14) have moved to the other side of the indication point (16), this connection has become apposite.
