摘要:
A lower supporting pin module 22 is given a shape having a contact surface 26a. On the occasion of position recognition for determining a position of a pin on the lower supporting pin module 22, an image of the lower supporting pin module 22 is captured, and the image is subjected to recognition processing, to thus detect an outer shape of an upper shaft 24B. Even when an extraneous matter on a downside surface of a substrate adheres to the contact surface 26a, the position of the lower supporting pin module 22 can be stably recognized with superior recognition precision.

A component mounting apparatus and a component mounting method which improve accuracy and a rate of placement of components onto a circuit-formed member. A component sucked by a suction nozzle is recognized at a component recognizing position, a deviation of the component from a normal suction status is determined on the basis of component recognition information obtained from this recognition of the component, and a velocity of conveyance of the component for a period of time following the recognition of the component and preceding placement of the component is controlled on basis of a magnitude of the deviation. By this control, the accuracy and rate of placement of components onto the circuit-formed member can be improved.

A navigation device for a vehicle comprises a current position detection unit for detecting a current position of the vehicle and a control unit. The control unit executes, when the detected current position approaches a point of guidance along a route, route guidance indicating a path to be taken at the point of guidance in order to go through the point of guidance along the route. The control unit also estimates a degree of traveling stability of a vehicle in traveling on a road and controls a timing to execute the route guidance so that the timing becomes earlier when the estimated degree of the traveling stability is smaller.
