PROBLEM TO BE SOLVED: To accurately identify a user position by using an electronic lock provided at an entrance of a room or a door including the electronic lock, as a reference.SOLUTION: An electronic lock according to a first embodiment is shown in Figs. 3A and 3B. The electronic lock 300 comprises: a case 301; a cylinder 302; a thumbturn 303 disposed on the case 301 at a position opposite to or a position substantially opposite to the cylinder 302; a first beacon 304 and second beacon 305 that are disposed inside the case 301; and an electromagnetic shielding member 306 disposed between the first beacon 304 and second beacon 305. From a radio wave from the first beacon 304, a first ID for identifying the first beacon 304 and radio wave intensity of the radio wave can be determined. The second beacon 305 is similar to the first beacon. The electronic lock is configured so that the first beacon 304's radio wave intensity is higher on the outdoor side, while the second beacon 305's radio wave intensity is higher on the indoor side.SELECTED DRAWING: Figure 3A 【課題】部屋の入口に設けられた電子錠又は電子錠を有する扉を基準としてユーザー位置の特定を高精度に可能にする。【解決手段】図３Ａ及び３Ｂに、本発明の第１の実施形態にかかる電子錠を示す。電子錠３００は、ケース３０１と、シリンダー３０２と、ケース３０１に対してシリンダー３０２と対向する位置又は実質的に対向する位置に配置されたサムターン３０３と、ケース３０１の内部に配置された第１の発信機３０４及び第２の発信機３０５と、第１の発信機３０４と第２の発信機３０５との間に配置された電磁波遮蔽部材３０６とを備える。第１の発信機３０４の電波からは、第１の発信機３０４を識別する第１のＩＤと、当該電波の電波強度を決定することができる。第２の発信機３０５も同様であり、室外側では第１の発信機３０４の電波強度がより強く、室内側では第２の発信機３０５の電波強度がより強くなるように構成されている。【選択図】図３Ａ
