Claim:
1. A rotation range-limiting device, comprising: a rotation body to which an object to be rotated is mounted; a stationary body rotatably supporting the rotation body; a slide-guiding portion as an arc-shaped groove disposed on either one of the rotation body and the stationary body, and having end walls formed at both ends thereof; a locking portion disposed on another of the rotation body and the stationary body; a slider movable along the slide-guiding portion, wherein when the slider abuts against the locking portion and either one of the end walls of the slide-guiding portion, the slider is stopped from rotation, and wherein as the rotation body rotates, the slider rotates together with the slide-guiding portion or the locking portion and abuts against both of the locking portion and either one of the end walls of the slide-guiding portion to stop a rotation of the rotation body; a motor disposed in the stationary body; a gear coupled to the motor; and a panning gear intermeshing the gear and formed in a peripheral wall of the rotation body.
