PROBLEM TO BE SOLVED: To provide a projector capable of easily adjusting the position of a picture. SOLUTION: A reflection mirror 4d has a rotary shaft 7, and the shaft 7 is inserted in the bearing part 8 of a housing 1. Therefore, the mirror 4d is rotatable with respect to the housing 1 and only the mirror 4d can adjust its installation angleαto the housing 1. When the angleαis changed, the reflection angleβof projected light 5 on the mirror 4d is also changed. Then, the shooting-up angle of the light 5 to the housing 1 is adjusted without changing the installation angle of the projector itself, as a result, the position of the projected picture is adjusted.
