  • Publication number: 20160328426
    Abstract: An information logger records rotation information on a spinning top and outputs the recorded information. A detachment detector detects that the spinning top is attached to the launcher. A rotation-rate detecting unit detects a rotation rate of the spinning top while a rotational force is applied to the spinning top. Rotation information of the spinning top derived from a result detected by a rotation-rate detecting unit is stored in a storage unit. The rotation information stored in the storage unit is sent to an information processor by a communication unit as required.

  • Publication number: 20160325190
    Abstract: A spinning top toy including a body and a separate shaft portion. The body has a first hook and the shaft portion has a second hook. The body and the shaft portion are switchable between couplable and decouplable states depending on a relative rotational position. The first hook and the second hook are vertically aligned in the couplable state, and are vertically misaligned in the decouplable state. An urging unit brings an upper face of the first hook and a bottom face of the second hook into contact by an urging force of a spring in the couplable state. The body and the shaft portion enter the couplable state by turning and pushing. The body and the shaft portion engage each other by bringing the upper face of the first hook into contact with the bottom face of the second hook by the urging force of the spring.

  • Patent number: 9435820
    Abstract: A rotation-rate detector detects a rotation rate of a spinning top and is fixed to or detachably attached to a launcher. The launcher applies a rotational force to the spinning top to launch the spinning top. The rotation-rate detector includes a detachment detector that detects detachment and attachment of the spinning top. The rotation rate of the spinning top is detected after the detachment detector detects attachment of the spinning top.
