Abstract
A heavy-weight object such as a motor is installed separately from a movable portion to reduce the weight of the movable portion. The invention includes a support unit, a movable unit to which equipment is attached, and a drive unit interposed between the support unit and the movable unit. The movable unit has a first rotating member rotatably attached to the support unit about a first rotation axis line and a second rotating member rotatably attached to the first rotating member about a second rotation axis line orthogonal to the first rotation axis line. The support unit is provided with paired first brackets positioned so as to sandwich the first rotating member, and these first brackets are each provided with a first shaft configuring the first rotation axis line. The second rotating member is provided with paired second brackets positioned so as to sandwich the first rotating member from a direction orthogonal to the paired first brackets, and the second brackets are each provided with a second shaft configuring the second rotation axis line and causing the first rotating member to rotatably support the second rotating member. The drive unit includes paired motors attached to the support unit and having a rotation axis line parallel to each of the first shafts, an endless belt wound between a pulley and each of the motors, and paired gears respectively attached to the first shaft and the second shaft adjacent to each other as a set and converting rotation about the first rotation axis line into rotation about the second rotation axis line. One of the gears is fastened to the pulley and is rotatably attached to the first rotating member, the other gear is fastened to the second bracket of the second rotating member, and to the first shaft to which the gear is not attached, the pulley provided to this first shaft and the first rotating member are fastened.
