PROBLEM TO BE SOLVED: To provide an optical mechanism position adjustment device capable of performing position adjustment of the optical mechanism of an optical unit so that an image can be projected to an appropriate position of the projection surface, when assembled in the device body.SOLUTION: An optical mechanism position adjustment device includes an attachment adjustment unit 73 and a tilt adjustment unit 74 for receiving a position adjustment instruction based on the positional relationship of a projection image and the projection plane E11a of a front screen mechanism E1, and adjusting attachment screws B223, arranged at four places different from a double nuts B275 arranged, respectively, at three places on the base B22 of a projector mechanism B2, based on the position adjustment instruction, thus adjusting the position of the projector 5, and the rotation of the projection light for adjustment emitted experimentally from the projector 5 about the optical axis.SELECTED DRAWING: Figure 15 |
