Claims

[Scope of utility model registration request]

In a variable slit device that forms a cross-sectional shape of a light beam into a predetermined shape by using a gap between a pair of slit plates that approach and separate from each other, a pair of rotatable rotating members are disposed between both ends of the pair of slit plates. A parallel link mechanism is constructed by connecting the ends of each of the slit plates to the corresponding rotating members by connecting members, and at least one of the rotating members or one of the slit plates is connected to the corresponding rotating member. A variable slit device characterized in that the width of the slit formed by the pair of slit plates is changed by operating it with an operating means.
