The invention provides a projection device which includes a rotating module and an imaging module. The rotating module is assembled on a mounting surface and includes a rotating part and an assembling part which are integrally formed. The rotating part is parallel to the mounting surface, and the assembling part is perpendicular to the mounting surface. The imaging module is assembled on the assembling part of the rotating module. When the rotating module rotates by taking an axis perpendicular to the mounting surface as an axial center, the rotating module drives the imaging module to rotate so as to change a projection direction of the imaging module. The projection device of the invention adjusts the projection direction without using a tool.

A projection system includes a screen, an image projection device configured to project an image on the screen, and a carrying platform on which the image projection device is mounted, and which is configured to move, wherein the carrying platform includes a projection direction variable part which is configured to change a projection direction of the image, and a support mechanism configured to support the screen so as to adjust a position of the screen in a direction crossing an installation surface on which the carrying platform is installed.

A projection system includes a projector configured to project image light and furniture on which the projector is mounted. The furniture includes a furniture main body, a setting section provided in the furniture main body and houses the projector, and an opening and closing member provided in an opening through which the image light passes, the opening and closing member switching a closed state in which the opening is closed and an open state in which the opening is opened. By aligning the opening and closing member with a position corresponding to a projection surface in the open state, a position of the projector is determined in a predetermined projection position with respect to the projection surface. The projector projects the image light onto the projection surface from the predetermined projection position to thereby form a rectangular projection image on the projection surface.

A projector stand includes an elevator member fitted to a strut such that the elevator member can be raised and lowered, a guide plate fixed to the upper end of the elevator member, a slide member horizontally movable along the guide plate, and a three-axis adjustment mechanism provided or the slide member.

A mobile projection device for projection mapping, the device comprising a road vehicle having a structure mounted on wheels, and at least one light projector unit mounted on the structure and configured to be controlled so as to provide projection mapping in the environment outside the mobile projection device.
