Abstract: A component mounting apparatus includes two board transfer devices, a component supply unit, a component placing device, a setting unit, and a controller. Until production of the urgent boards is instructed, the two board transfer devices and the component placing device mount components on the regular boards in accordance with a first mounting program stored by the controller. When production of the urgent boards is instructed, a regular board is unloaded from the other board transfer device, which has been set by the setting unit to transfer urgent boards, the transfer way width of the other board transfer device is adjusted to the width of the urgent boards, and the other board transfer device and the component placing device are controlled so that component mountings on the urgent boards are performed on the other board transfer device in accordance with a second mounting program stored by the controller.

Abstract: Disclosed is an electronic component mounting apparatus, which is provided with a board transfer device for transferring circuit boards and a pair of component supply devices arranged with the board transfer device therebetween for supplying electronic components on the boards. Of the component supply devices, one of them is designated as main component supply device for primarily supplying the electronic components on the boards, and the other is designated as secondary component supply device for supplying the electronic components as long as the component supply from the main component supplying device is discontinued. The electronic component mounting apparatus performs a switching control so that the electronic components are supplied from the main component supply device during the ordinary mounting operation, but from the secondary component supply device when th component supply from the main component supplying device is discontinued.
