Claims

[Claims for Utility Model Registration] (1) A projector that irradiates an object with light from a light source and projects an image of the object onto a screen through a lens, the projector having the light source and the lens; a main body having a projection aperture that guides light to the object to be projected; and a setting surface on which the object to be projected is set; A projector comprising: a projection table that covers the projection aperture and is movable in a plurality of directions. (2) Utility Model Registration The projector according to claim 1, wherein the projection table moves in a front-back direction from the reference position with respect to the screen. (3) Utility Model Registration The projector according to claim 1, wherein the projection table moves from the reference position to the left and right with respect to the screen. (4) Utility Model Registration The projector according to claim 1, wherein the projection table is movable in the front-rear direction and left-right direction from the reference position with respect to the screen. (5) Utility Model Registration The projector according to claim 1, wherein the amount of movement of the projection table from the reference position differs depending on the direction of movement. (6) Utility Model Registration The projector according to claim 1, wherein the projection table moves the same amount from the reference position in a plurality of directions. (7) Utility Model Registration The projector according to claim 1, wherein the end of the projection table does not move inward from the edge of the projection aperture. (8) Utility Model Registration The projector according to claim 1, wherein the projection table is provided with a cover that can be opened and closed to cover the setting surface. (9) Utility model registration The projector according to claim 8, wherein the projection table is equipped with a detector that detects opening and closing operations of the cover over the entire moving area. .
