To provide a notification device, a notification system, and an elevator system capable of suppressing a distance between passengers from becoming shorter.SOLUTION: The notification device comprises: a reception unit that receives, from a piezoelectric detector, a signal indicating pressure received from an object present on a floor surface of a car by the piezoelectric detector provided on the floor surface; a position detection unit that identifies positions of passengers present in the car on the basis of the signal from the piezoelectric detector received by the reception unit, and detects presence of passengers in either a plurality of first sections not adjacent to each other among a plurality of sections set by dividing a region of the floor surface or one or more second sections which are not the first sections among the plurality of sections; and a notification unit that determines presence of the second sections in which the passengers are present on the basis of results detected by the position detection unit, and generates, when it is determined that there is the first section in which no passenger is present, a first notification command for notifying the inside of the car of promotion of movement to the first section.SELECTED DRAWING: Figure 1

    【課題】乗客どうしの距離が近くなることを抑制できる報知装置、報知システムおよびエレベーターシステムを提供する。【解決手段】報知装置は、かごの床面に設けられた圧電検出装置が床面に存在する物体から受ける圧力を示す信号を圧電検出装置から受信する受信部と、受信部が受信した圧電検出装置からの信号に基づいてかごの内部に存在する乗客の位置を特定し、床面の領域を分割して設定された複数の区画のうち互いに隣り合わない複数の第1区画および複数の区画のうち第1区画でない1以上の第2区画のいずれかに乗客が位置することを検出する位置検出部と、位置検出部が検出した結果に基づいて、乗客が位置している第2区画が存在すると判定し、かつ乗客が位置していない第1区画が存在すると判定した場合に、第1区画に移動するよう促す旨をかごの内部に報知させる第1報知指令を作成する報知部と、を備えた。【選択図】図1
