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. The second attacking member is restrained at the third position when the first attacking member is at the first position and is released from restraint to be moved to the fourth position when the first attacking member is at the second position.

Abstract: A toy top includes a body and a bump for attack which is disposed on a circumference of the body. The bump moves up and down according to a force acting on the bump while the toy top spins.

Abstract: A toy top includes a shaft part having, as a shaft center, an axis that coincides with a center of rotation. A lower end portion of the shaft part includes a shaft tip part and an annular member. The shaft tip part includes a contact member. The annular member is movably disposed around the shaft tip part in an extending direction of the axis. In a normal state in which the axis is perpendicular to a contact surface, the contact member protrudes from the annular member downward, and only the contact member contacts the contact surface. When the axis of the shaft part inclines with respect to the contact surface, the contact member and the annular member contact the contact surface.

Abstract: [Problem to be Solved] The present invention has an objective to improve operability in information input in an information processing device that includes a head mounted display to enable head tracking display. [Solution] An information processing device includes a hand-held operation unit (10), a head mounted display (20), a first motion sensor (506 to 508) that can detect at least the orientation of the head of the operator, and an information processing unit (30) that executes a head tracking displaying process in which the first motion sensor is used, and a specific process corresponding to an indication of the operator identified by the motion of the operation unit, wherein the motion of the operation unit is detected using a second motion sensor (1603 to 1605) incorporated in the operation unit.
