Abstract
Provided is a heat-resistant imaging camera configured to move in a high temperature furnace and configured to capture high-definition images of the outer side or the inner side of a painted object passing in a high temperature drying furnace. Heat insulators (to) are attached to all inner surfaces of an outer case () of a heat-resistant imaging camera () except a double glass window (), and cold storage material packs (to) are disposed inward of the heat insulators (to) in layers so as to cover around a camera (). Intrusive heat is absorbed by melting latent heat when the cold storage material packs (to) are melted and changed in phase from a solid to a liquid at a specific temperature or higher, thereby ensuring heat resistance that maintains the camera () at a safely operatable temperature.
