PROBLEM TO BE SOLVED: To provide electric equipment with a dust detecting function in which the number of components are reduced, whose manufacturing cost is reduced, and which can warn a user of the deposition of dusts and is excellent in safety. SOLUTION: This video integrated type television device is provided with a light guiding part 80 for guiding infrared rays from an infrared ray LED 50a being a light emitting part configuring a reel sensor 50 for detecting the rotation of a reel to a photo-transistor 55b being a first light receiving part configuring a dust detection sensor 55, and configured to issue predetermined warning when the infrared rays to be guided to the photo-transistor 55b by the optical guiding part 80 are interrupted by deposited dusts.
