Information logger

摘要

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.

主权项

1. An information logger that records rotation information of a spinning top, comprising:
an attachment on the logger that detachably attaches a separate launcher that includes a rotational mechanism and that applies a rotational force to the spinning top; a rotation-rate detector that detects a rotation rate of the spinning top during application of the rotational force by the launcher to the spinning top; a storage unit that stores the rotation information of the spinning top acquired based on a result detected by the rotation-rate detector; and an output unit that outputs the rotation information stored in the storage unit.
