Abstract: A sample cartridge has a sample stand and an inclining mechanism. A sample cartridge holding apparatus has a housing part which is inclined. When the sample cartridge is inserted into the housing part, a contact portion contacts a lever of the inclining mechanism, and the sample stand is inclined by a predetermined angle. With this process, an appropriate inclination angle is realized for the sample stand.

Abstract: An observation coordinate in the device coordinate system of an observation device is converted into an observation coordinate in a virtual coordinate system, using a conversion formula. Subsequently, the observation coordinate in the virtual coordinate system is converted into an observation coordinate in the device coordinate system of another observation device, using a reverse conversion formula. The virtual coordinate system is a logical coordinate system that does not depend on any device coordinate system.
