PURPOSE: To provide a function which can adjust an action speed and the timing discrepancy of an action between a component feed operation and a component pushing-up pin in a device which drives a parts cassette for an electronic- component mounting machine.

CONSTITUTION: First members (a lever 11, a roller 13, a link 14, a crank 15) are moved around a fulcrum 12 when a stepping motor 16 is driven. They push a feed lever 13, feed a component tape and interface with second members (a pusher 17, links 18 and 19, a spring 20). Thereby, the pusher 17 pushes a rod 104 which moves a component pushing-up pin (not shown in the figure). Their action speed and their timing can be adjusted by controlling the stepping motor 16.
