して投影可能としたことを特徴とする投影機。 In a projector capable of projecting different types of materials using first to fourth optical systems, the projector includes an operating member, a first cam and a second cam rotated by the operating member, and a projection lens that rotates in conjunction with the first cam. a lens moving member that moves the lens forward and backward;
a first lever that switches between the first and second optical systems by changing the reflection angle of the movable mirror; and a first lever that switches between the first and second optical systems by changing the projection lens in conjunction with the second cam; The first to third optical systems and the fourth optical system are switched by inserting and removing a second movable mirror into and from the optical path in conjunction with a second switching lever and the second cam to change the projection optical path. A projector comprising: a third lever, the projector being capable of selecting any one of the first to fourth optical systems for projection by rotating the operating member.
