To provide an elevator intercom, an elevator, and an elevator system that are able to prevent an erroneous operation performed by a user.SOLUTION: An intercom 26 includes a photoelectric sensor 32, an illuminance sensor 31, and a control unit. The photoelectric sensor 32 includes a light projecting unit 32a that projects light L1, and a light receiving unit 32b that receives the light L1 from the light projecting unit 32a, and the photoelectric sensor is turned on when the light L1 from the light projecting unit 32a is blocked. The illuminance sensor 31 is turned on when a detected amount of light decreases to a threshold value. When both the photoelectric sensor 32 and the illuminance sensor 31 are turned on, the control unit determines that the operation has been performed.SELECTED DRAWING: Figure 3

    【課題】利用者による誤操作を抑制できるエレベーターのインターホン及びエレベーター、エレベーターシステムを提供する。【解決手段】インターホン26は、光電センサ32と、照度センサ31と、制御部と、を備えている。光電センサ32は、光L1を投光する投光部32a及び投光部32aからの光L1を受光する受光部32bからなり、投光部32aからの光L1が遮蔽された際にONとなる。照度センサ31は、検知される光量が閾値まで低下するとONとなる。制御部は、光電センサ32と照度センサ31の両方がONとなった場合に、操作が行われたと判断する。【選択図】図3
