Abstract
A lead frame magazine fastening structure used with, for instance, a semiconductor bonding machine including raising-and-lowering shafts passing through a magazine setting plate of an elevator device and a positioning assembly comprising pins and a vacuum suction pad provided in the magazine setting plate. A lead frame magazine for accommodating lead frames in a stacked fashion is comprised of a bottom plate and vertical side bars along with a magazine supporting plate placed on the bottom plate and is placed on the magazine setting plate of the elevator device. When the elevator device is actuated, the raising-and-lowering shafts raise only the magazine supporting plate on which the lead frames are placed while the bottom plate of the magazine is held on the magazine setting plate of the elevator device by the positioning assembly.
