Abstract: A resin curing device for curing photo-curing resin applied to a nail. The resin curing device includes a light source and a controller controlling light irradiation to photo-curing resin. The controller changes an irradiated light quantity in an irradiation period to adjust a gloss level when photo-curing resin is cured. Accordingly, the resin curing device can adjust the gloss level of photo-curing resin when it is cured.

Abstract: The present invention provides resin curing device for radiating light to cure light curable resins of different kinds. The device has flash lamp for emitting irradiation light in a wavelength range including at least a wavelength for curing the light curable resins of different kinds, and control section. Control section causes flash lamp to emit the light at a frequency of plural times per second, and controls a total irradiation energy of the light in the wavelength range to be not less than 0.1 J/cm2 but not more than a level that cause low-temperature burn on a finger and toe. The device cures various types of light curable resins with difference in wavelength of light for curing, but also offers safety with no worry about causing low-temperature burn on the human body.
