Electric-component mounting apparatus

An apparatus for mounting at least one electric component supplied by an electric-component supplying device, on a circuit substrate supported by a circuit-substrate supporting device, the apparatus comprising:

• a nozzle moving device which moves a suction nozzle having an end surface that applies a suction to the electric component and thereby holds the component, in a direction intersecting an axis line of the suction nozzle;
• an elevating and lowering device which elevates and lowers the suction nozzle so that the suction nozzle performs at least one of receiving the electric component from the electric-component supplying device and mounting the component on the circuit substrate on the circuit-substrate supporting device;
• an elevator member which is connected to the suction nozzle;
• a downward-movement control device which changes, while the apparatus performs an electric-component mounting operation, at least one of a position of an end of a downward movement of the suction nozzle caused by the elevating and lowering device and a position where a deceleration of the downward movement of the nozzle is started;
• and
• the downward-movement control device comprising
• a lever which is pivotable about an axis line and has an arm;
• a first movable member which is supported by the arm of the lever such that the first movable member is movable relative to the arm in a lengthwise direction of the arm, the first movable member being connected to the elevator member;
• and
• a first-movable-member moving device which moves the first movable member in the lengthwise direction of the arm.
