To make a lens for receiving light less noticeable, on a security device.SOLUTION: A security device includes: a housing with a window part; a light receiving part which is disposed inside the housing and to which first light is input; a light projection part disposed inside the housing and outputting second light; and a light guide lens provided between the window part and the light receiving part and the light projection part. The light guide lens includes: a light entering/emitting surface which first light enters and from which second light is emitted, via the window part; a light emitting surface which is opposed to the light receiving part and from which first light is emitted; and a light entering surface which is opposed to the light projection part and which second light enters.SELECTED DRAWING: Figure 3 【課題】セキュリティ装置において、光を受光するためのレンズを目立たなくさせる。【解決手段】セキュリティ装置は、窓部を有する筐体と、筐体内に配置され、第１光が入力される受光部と、筐体内に配置され、第２光を出力する投光部と、窓部と、受光部および投光部との間に設けられた導光レンズと、を備える。導光レンズは、窓部を通じて、第１光を入光させ、第２光を出光させる入出光面と、受光部に対向し、第１光を出光させる出光面と、投光部に対向し、第２光を入光させる入光面と、を有する。【選択図】図３
