Abstract
A hand position identification device includes a rotation detection unit that detects a rotation state of a rotor by using an induced voltage generated in a motor for rotating a hand, a storage unit that stores a timing information piece relating to a timing at which the induced voltage exceeds a predetermined threshold, and a control unit that compares a first timing information piece stored in the storage unit and obtained in a case where the hand is located at a first position, with a second timing information piece obtained in a case where the hand is located at a second position, and that identifies the second position as an identified position in a case where a difference between the first timing information piece and the second timing information piece is equal to or more than a predetermined amount.
