A stocker that stores a stylus in a replaceable manner with the spindle of the measuring machine, or a machining tool necessary for machining a work placed on a pallet thereof, and a stylus necessary for measurement. You may make it provide the stocker stored exchangeably with the main shaft of a measuring device and a measuring device.

If a pallet is provided for each pallet with a stocker for storing a measuring element required for measuring a work placed on the pallet, when one of the pallets is carried into the measuring station, the state is changed. The work on the pallet can all be measured while exchanging the probe. Therefore, compared to a device in which all the probes are intensively stored in one pallet, the probes can be exchanged more quickly.
In addition, measurement efficiency can be improved.

[0014] If a pallet is provided for each pallet with a stocker storing machining tools necessary for machining a work placed on the pallet and a stylus required for measurement, the pallet is loaded into the machining station. In this state, all the workpieces on the pallet can be machined while exchanging tools, and at the measuring station, all the workpieces on the pallet are measured while exchanging the probe while the pallet is being loaded. be able to. Needless to say, in these cases as well, it is possible to standardize the stocker that stores the processing tool and the stylus, and the processing machine and the measuring machine can be installed in a small space.
