Ultraviolet ray irradiation device and ultraviolet ray blocking unit

An ultraviolet ray blocking unit which is detachably mounted on a sterilization chamber housing of an ultraviolet ray irradiation device which sterilizes a surface of a glove which is mounted on a hand of an operator and is made of an ultraviolet ray non-transmitting material by irradiating ultraviolet rays to the glove, the ultraviolet ray blocking unit preventing irradiation of the ultraviolet rays to the outside of the ultraviolet ray irradiation device when the operator inserts the glove into the ultraviolet ray irradiation device, wherein

• the ultraviolet ray irradiation device comprises:
• a sterilization chamber housing formed of an ultraviolet ray blocking member configured to block the ultraviolet rays, the sterilization chamber housing having a sterilization chamber in the sterilization chamber housing, and having an insertion opening through which the hand on which the glove is mounted is insertable into the sterilization chamber;
• an ultraviolet ray irradiation unit disposed in the sterilization chamber housing and configured to irradiate the ultraviolet rays to the sterilization chamber,
• the ultraviolet ray blocking unit comprises:
• an ultraviolet ray blocking elastic body formed of a thin plate-like member having ultraviolet ray non-transmitting property and elasticity, disposed so as to traverse an insertion direction of the hand when the hand on which the glove G is mounted is inserted into the sterilization chamber through the insertion opening, and allowing the hand on which the glove G is mounted to penetrate the ultraviolet ray blocking elastic bodies;
• and
• a frame body disposed along a peripheral edge portion of the insertion opening, the frame body allowing the respective ultraviolet ray blocking elastic bodies to be mounted on the frame body by supporting peripheral edge portions of the respective ultraviolet ray blocking elastic bodies in a state where a plurality of the ultraviolet ray blocking elastic bodies are stacked, and
• the ultraviolet ray blocking elastic body is formed such that a plurality of cuts are formed in the ultraviolet ray blocking elastic body along a plurality of lines extending radially from a predetermined position on a plate surface of the ultraviolet ray blocking elastic body toward a peripheral edge portion of the ultraviolet ray blocking elastic body thus forming the plurality of elastic members between the cuts, wherein a distal end portion of each of the plurality of elastic members which is positioned on a side of the predetermined position forms a free end which is freely movable in a frontward and backward direction of the ultraviolet ray blocking elastic body, and
• the respective ultraviolet ray blocking elastic bodies mounted on the frame body are mounted on the frame body such that the plurality of cuts formed in at least one ultraviolet ray blocking elastic body among the respective ultraviolet ray blocking elastic bodies are displaced with respect to the plurality of cuts of other ultraviolet ray blocking elastic bodies along the plate surfaces.
