Description

  The present invention relates to a microscope apparatus including a storage unit that stores a power supply module.

  Conventionally, in the fields of medicine and biology, a microscope for illuminating and observing a specimen is used for observing cells and the like. In the industrial field, microscopes are used for various purposes such as quality control of metal structures, research and development of new materials, inspection of electronic devices and magnetic heads, and the like. A general microscope has a power supply unit that supplies power to an illumination system or the like. Since most of the power supply sources for the microscope are household power supplies, power is usually supplied to the microscope after voltage conversion and AC to DC conversion by a transformer.

  There are two types of transformers: one that uses an internal circuit and one that is externally attached as an AC adapter. However, because it is easy to maintain and can reduce the effects of heat and electrical noise, many external methods are used. ing. On the other hand, when the transformer is externally attached, it is separate from the microscope main body, and thus there is a problem that the AC adapter becomes an obstacle during observation, and the transportability and storage property are inferior.

  As a technology to improve the portability and storage of external AC adapters, an AC adapter storage unit with a plug insertion port is provided in the microscope body, and the plug of the plug-integrated AC adapter is inserted into this plug insertion port. Discloses a microscope capable of fixing an AC adapter (see, for example, Patent Document 1).
