Claims

[Scope of utility model registration request]

A first pulse generating means for generating an encoded first pulse train, and a second pulse for generating an encoded second pulse train at a timing different from the pulse generation timing of the first pulse train. A key having a generating means and inserted into and removed from the key hole, and first and second pulse generating means provided corresponding to the first and second pulse generating means, respectively, and generating a pulse train when the key is inserted into and removed from the key hole. a second detector;
first and second reading circuits that read the pulse trains from the first and second detectors, respectively, and first and second setting encoded signals corresponding to the forty-first and second pulse trains, respectively; first and second reading circuits that respectively compare a selected setting coded signal among the stored setting coded signals and read signals of the first and second reading circuits, and output a match signal when the two match; A second memory comparison circuit, a neutral power circuit that outputs an output signal when both the first and second memory comparison circuits output matching signals, and which of the first and second detectors is selected first. detecting whether the key is inserted into or removed from the keyhole, and determining whether the key is inserted or removed from the keyhole, and when it is determined that the key is inserted or removed from the keyhole, causing the first memory comparison circuit to select a first setting encoded signal. At the same time, the second memory comparison circuit selects a second setting encoded signal, and when it is determined that the tail is the tail, the first and second memory circuits select a setting encoded signal opposite to the elegy. an electronic key device comprising a determination circuit that disables the output circuit when it is determined that the electronic key has been removed.
