  • Apparatus for measuring characteristics of chip electronic components
    Patent number: 4978913
    Abstract: Fixed terminals and movable terminals are arranged on both sides of a turn table, which is provided along its circumferential direction with a plurality of holding holes for receiving chip electronic components so that both end portions thereof project from the holding holes. The movable terminals are provided by parts of a printed circuit board or elastically flexible plate members such as plate springs, and they are elastically brought into contact with electrodes which are formed on first end surfaces of the chip electronic components. Due to such elastic contact of the movable terminals, electrodes formed on the other end surfaces of the chip electronic components are pressed into contact with the fixed terminals.
