Abstract

A projector suspension device includes a base fixed to a wall, a support member extending from the base and supporting the projector, and an adjustment mechanism that adjusts rotation and a position of the projector. The adjustment mechanism includes a first slide substrate that slides with respect to the support member in a first direction perpendicular to the wall and adjusts the position of the projector in the first direction, a substrate fixed to the first slide substrate, a first rotating substrate that rotates with respect to the substrate, a second rotating substrate that rotates with respect to the first rotating substrate about an axis parallel to the wall and perpendicular to the substrate, and a turning member that adjusts a rotation of the second rotating substrate and has a rotating pivot perpendicular to the base. The second rotating substrate rotates about the axis by rotation of the turning member.
