Abstract: A doll toy head rotation device of which the head parts can be switched instantly and in which because the head parts are rotated inside the chest part and the back part with these parts fully open the head parts can be switched smoothly without catching on anything. A front plate 43 is open/closably mounted in a front opening 15 in a torso part 11, a rear plate 50 is open/closably mounted in a rear opening 17, and an upper plate 60 is rotatably mounted in an upper opening 16. An upper head part 70 is mounted on the upper surface of the upper plate 60 and a lower head part 72 is mounted on the lower surface. The front plate 43 and the rear plate 50 are linked together and open substantially simultaneously. A pinion 66 is provided on the upper plate 60. A rack 54 which meshes with the pinion 66 is provided on the rear plate 50. When the rear plate 50 opens, the pinion 66 rotates and inverts the upper plate 60.

Abstract: Doll with head turning mechanism including a pair of opposed doll heads mounted on an upper plate mounted rotatably in an upper or neck opening provided on the trunk portion of the doll. The trunk portion is provided with openable and closeable internal cavity providing apparatus. One doll head is normally exposed and the other doll head is normally received and concealed in the internal cavity. Upon the operator of the doll rotating the normally exposed head, the normally exposed head is rotated, received and concealed in the internal cavity and the normally concealed head is rotated into an exposed position. The upper plate and the cavity providing apparatus are provided with engageable members which engage upon the doll heads being reversed and prevent the upper plate from rotating and returning the doll heads to their original positions under the influence of a bias member which biases the upper plate to normally maintain the doll heads in their original positions.
