Abstract: A toy top includes a shaft portion, an additional part and an engaging part. The shaft portion includes a spinning shaft. The additional part is attached to the shaft portion movably in an axis direction of the spinning shaft. The engaging part engages the additional part with the shaft portion at different positions in the axis direction of the spinning shaft. An attachment position of the additional part is changeable by changing engagement of the additional part by the engaging part. A grounding state or a height of the shaft portion is changeable according to change of the attachment position of the additional part.

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.

Abstract: A toy top includes a shaft portion, a body and an attacking member. The body is rotatable relative to the shaft portion in response to an impact applied to the body. The attacking member is movably connected to the body to move in a predetermined direction relative to the body between first and second positions. In the second position, the attacking member protrudes from the body a variable protruding distance which varies according to the rotating position of the body relative to the shaft portion.

Abstract: A toy top includes a shaft portion, a body, and a first attacking member and a second attacking member that are disposed at different circumferential direction positions of the body. The first attacking member is movable between an inner first position and an outer second position in a radial direction. The second attacking member is movable between an inner third position and an outer fourth position in the radial direction. The first attacking member is biased toward the first position and is movable to the second position by centrifugal force.

Abstract: A toy top includes a body, a shaft portion, a movable component and a biasing member. The movable component includes at least a portion of the body and is movable upward and downward along the rotational axis of the toy top. The biasing member urges the movable component upward or downward. The movable component has a circumferential face that flares away from the biasing direction of the biasing member as the circumferential face recedes from the rotational axis. When the circumferential face collides with an opponent toy top, the movable component moves against a biasing force of the biasing member in a direction opposite to the biasing direction, and then the movable component is urged by resilience of the biasing member, so that the opponent toy top is moved in the biasing direction.

The second extensions stepwise vary their positions relative to the first extensions when the first body part rotates relative to the shaft portion. The second extensions move into the spaces between the first extensions when the first body part rotates relative to the second body part.

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.
