<p>PROBLEM TO BE SOLVED: To provide an object movement memorizing device using electromotive force generating means and current direction memorizing means, which is configured to surely memorize that an object has been moved even if the moved object is restored to an original state.SOLUTION: An object movement memorizing device 100 comprises: electromotive force generating means 11 that has a detecting magnet 11a and a detecting coil 11b that can be relatively moved reciprocatingly in linking with a reciprocating movement of an object OB, generates currents in a first direction in response to a forward movement of the object OB and generates currents in a second direction D2 opposite to the first direction D1, in response to a backward movement of the object OB; current direction memorizing means 13 that is connected to the electromotive force generating means 11 and detects and memorizes directions of currents generated by the electromotive force generating means 11; and rectifying means 25 that is provided between the detecting coil 11b and the current direction memorizing means 13 and designed to flow currents only in the first direction D1 to the curent direction memorizing means 13.</p> |
