2. Description of the Related Art There is known a component mounting apparatus (mounter) for mounting an electronic component such as a semiconductor element at a predetermined position on a printed circuit board or the like (hereinafter referred to as a "board"). The component mounting device moves the work head to a supply position of the electronic component supplied from the component supply device, and sucks the electronic component by the suction nozzle. The component mounting apparatus captures an image of the electronic component sucked by the suction nozzle from a predetermined direction, and obtains a shift amount from the reference position of the electronic component in the sucked state. The component mounting apparatus corrects the obtained shift amount, moves the work head to the mounting position on the substrate, releases the electronic component from the suction nozzle, and mounts the electronic component accurately on the substrate.

In recent years, there has been known a component mounting apparatus that includes a plurality of component supply cassettes and can mount a plurality of types of electronic components on a substrate. Such a component mounting apparatus generally includes a plurality of removable component supply cassettes in which electronic components are arranged at predetermined intervals on a tape, and the tape is wound up and stored on a predetermined reel. The component mounting device is provided with two component supply stages for mounting dozens of component supply cassettes, and by mounting component supply cassettes containing electronic components necessary for each component supply stage in any combination, In the same process, a plurality of types of electronic components can be mounted on a substrate.

Recently, there has been known a component mounting apparatus including a cassette batch mounting / detaching apparatus capable of batch mounting / detaching such a plurality of component supply cassettes. The cassette batch attachment / detachment device has a mounting stage for mounting a plurality of component supply cassettes, and when it is mounted on the mounting table of the component mounting device, supplies the electronic components from the mounted component supply cassette to the component mounting device. I do. For example, an operator mounts a component supply cassette containing necessary electronic components on a batch mounting / detaching device, and then mounts the cassette batch mounting / dismounting device on one of two mounting tables provided in the component mounting device. The operator can check the electronic components stored in each of the component supply cassettes mounted on the cassette batch attachment / detachment device, the supply positions of the electronic components supplied from each of the component supply cassettes, and the mounting positions of the electronic components on the board.
