2. Description of the Related Art Exhibits housed in display cases are often of high cultural value, such as antiquities, and the temperature and humidity inside the display cases must be kept high in order to preserve them in good condition. Systems for monitoring have been developed. As this type of conventional device, various sensors are arranged in the display case, and the output signals of these sensors are connected by wire to an information processing device provided outside the display case to enable recording and monitoring. Also, there is known a small measuring instrument having a recording function having a function of recording on a recording sheet, which can be arranged in an exhibition case.

[0003]

However, in the former case described above, for example, the wiring must be routed from the display case to the outside. Therefore, in an exhibition case fixed to a building, it can be effective because the wiring can also be fixed, but in order to use it in an exhibition case configured to be movable on the floor so that the layout can be changed, the wiring can be routed. It is not practical in the field of display cases where the appearance is important and the processing is a problem.

On the other hand, in the latter case described above, since an independent monitor system can be constructed for each exhibition case, it can be used for a movable exhibition case. However, since the system itself is housed inside the display case, real-time data monitoring cannot be performed, which may delay the treatment in the event of an abnormality. In addition, since it is necessary to replace the recording paper that also checks the data, the exhibition case is opened and closed each time. This is not preferable for the preservation of the exhibit.

[0005]

In view of such a problem, the present invention is configured to wirelessly transmit the status information in the display case to an external information processing means, which is independent. The main object of the present invention is to provide an information collection device for an exhibition case that can be applied to a movable exhibition case without damaging the appearance due to wiring or the like and that can monitor the internal condition in real time.
