り省スペース化できない。The above conventional light irradiators are not necessarily satisfactory in terms of downsizing for the following reasons. For example, the light irradiator shown in FIGS. 3 (a) and 3 (b) does not save space because it requires extra space in the blind shutter or the door shutter, so that the light irradiator and the shutter are not covered. The distance to the illuminated object becomes longer. In addition, in the case of a blind shutter, some light is blocked or reflected even when the shutter is opened, resulting in light loss. Also,
In the light irradiator shown in FIG. 3D, an extra space is provided in the shutter part of the rotating mirror, so that the distance between the light irradiator and the object to be irradiated becomes long. Further, in the light irradiator shown in FIG. 3C, the distance between the light irradiator and the object to be irradiated is long, and the mirror 2'c
Needs space to rotate 180 degrees, but it can't save much space as well.

電力が一定の場合には、高さｈを高くすれば、第２焦点
ｆ２における照度を高めることができる。FIG. 2 is an illustration of how to provide a light shield. As in this embodiment, when the light from the rod-shaped lamp 1 is condensed by the elliptical cross-section condensing mirror, the light beam center of the lamp 1 is located at the position of the first focus f 1 of the elliptical cross-section condensing mirror. On the other hand, while the work transfer line is positioned at the position of the second focus f 2 . It is generally desirable that the illuminance at the second focal point f 2 is high to determine how much light the work conveyed on the conveyance line receives. Here, the illuminance at the second focal point f 2 depends on the area of the surface (referred to as an effective reflection surface) of the elliptic cross-section condenser mirror that can effectively reflect and condense light when the power of the lamp 1 is constant. To do. Therefore, referring to FIG. 2, when the irradiation distance (that is, the focal length) and the power of the lamp are constant, the illuminance at the second focus f 2 can be increased by increasing the height h.

る。On the other hand, in the case where the elliptical gutter-shaped converging mirror having the cross section is composed of two long plate-shaped mirrors 15 and 16 as in the present embodiment and is made to swing by the swing drive mechanism so as to be used also as the shutter, If the height h in FIG. 2 is increased, a space for swinging is required, and the size reduction of the light irradiator cannot be achieved. Therefore, the height h of the effective reflection surface is appropriately determined in consideration of the required illuminance and the required degree of miniaturization.

It is desirable that there is no shield in this effective ray area. Therefore, it is desirable that the light shields 15a and 16a necessary for preventing light leakage in the closed state shown in FIG. Specifically, it is desirable to dispose not as A shown in FIG. 2 but as B. However, in the present embodiment, the inclined surfaces 15b and 16b are located at the lowest points T and T'and the first point T and T ', respectively, in order to minimize the light shielding property at the time of closing shown in FIG. The two focal points f 2 are arranged on a straight line. Therefore, the "predetermined angle" referred to in the claims for utility model registration means the straight line Tf 1 and B shown in FIG.
And the inclined surface 15b (first

The a and 16a are integrally formed with the long plate mirror. It can be installed by screwing, etc.,
This is preferable because deformation due to thermal expansion does not occur, and screws do not loosen and fall into the object to be irradiated due to repeated opening / closing operations, which damages the object to be irradiated.
