  • Patent number: 4606117
    Abstract: Apparatus for automatically mounting chip type circuit elements on printed circuit boards is constructed in a manner to mount a feed wheel for carrying out the delivery of a chip tape on a lower frame. A lever is mounted with respect to the feed wheel through a one way clutch, so as to allow the lever to be pressed by a cam provided on a reciprocating upper frame which supports a mounting head. The feed wheel is thus rotated in the actuating direction of the one-way clutch to intermittently feed the chip tape and permit another chip type circuit element to be disposed at a chip type circuit element removing position, each time when the mounting head is returned to its original position.
