  • Chip alignment/feed apparatus
    Patent number: 5806715
    Abstract: A bulk cassette has a container chamber at its rear end, and an outlet port at its front end. A plurality of chips within the container chamber are discharged from the outlet port one by one in an aligned fashion. A chip case is detachably connected to the rear end of the bulk cassette and includes an internal container space within which a plurality of chips can be contained. The chip case has a supply opening at its front end so as to feed the chips from the container space to the container chamber of the bulk cassette. The chip case also has a receiving opening at its rear end so as to feed additional chips into the container space. A closure member is mounted to the rear end of the chip case to open and close the receiving opening. A pipe is inserted into the receiving opening for replenishment of chips.
