Patent ID: 7966718

Claim:
A component mounting apparatus comprising: a substrate holding device which fixes and holds a circuit substrate; a component supplying device which supplies a plurality of circuit components; a head support portion; a mounting head which is detachably attached to the head support portion and which, in a state in which the mounting head is attached to the head support portion, is operated to take each of the circuit components supplied by the component supplying device, and mount said each circuit component on a surface of the circuit substrate fixed and held by the substrate holding device, wherein the mounting head has a rear portion that has an upper half and a lower half, wherein the lower half has a lower portion that is positioned to the lower half-side of a middle line that divides the upper half and the lower half, and wherein the mounting head has, in the lower portion thereof, at least one leg portion, and the head support portion has at least one leg support portion configured to support a lower end of said at least one leg portion of the mounting head from a lower side of said at least one leg portion; and a forcing means comprising an elastic member which is supported by the head support portion and which forces, owing to an elastic force thereof, the rear portion of the mounting head rearward toward a front portion of the head support portion, and additionally forces, owing to the elastic force thereof, said at least one leg portion of the mounting head downward toward said at least one leg support portion of the head support portion, so as to attach the mounting head to the head support portion.
