To provide a work machine wireless operator leaving-behind prevention device capable of easily and inexpensively preventing a wireless operator from being left behind without providing a dedicated housing part or the like.SOLUTION: This leaving-behind prevention device is provided with: a passive tag 50 that is attached to a wireless operator 10; a reading device 51 that has a transmission unit 511 for radiating an electric wave into a driving cab 4 and a reception unit 512 for receiving the electric wave; a leaving-behind warning device 52 that issues a warning in response to a warning output command received from the reading device 51; and a traveling detection device 53 that detects that one of a releasing operation of a parking brake and a disconnection operation of a PTO mechanism has been carried out. The reading device 51 starts electric wave radiation from the transmission unit 511 when it is determined that one of the releasing operation and the disconnection operation has been carried out on the basis of a detection signal from the traveling detection device 53, and outputs the warning output command to the leaving-behind warning device 52 when a response signal is not received from the passive tag 50 even after the passage of a preset time.SELECTED DRAWING: Figure 2

    【課題】専用の収容部などを設ける必要がなく、容易に、且つ安価に無線操作器の置き忘れを防止することが可能な作業機用無線操作器の置き忘れ防止装置を提供する。【解決手段】置き忘れ防止装置は、無線操作器10に取り付けられたパッシブタグ50と、運転室4内に電波を放射する発信部511と電波を受信する受信部512とを有する読み取り装置51と、読み取り装置51からの警報の出力指令を受けて警報を発する置き忘れ警報装置52と、パーキングブレーキの解除操作又はPTO機構の断操作のいずれか一方が行われたことを検出する走行検出装置53とを備え、読み取り装置51は、走行検出装置53からの検出信号に基づき解除操作又は断操作のいずれかが行われたと判定すると、発信部511からの電波の放射を開始し、予め設定した時間が経過してもパッシブタグ50からの応答信号が受信されない場合に、置き忘れ警報装置52に警報の出力指令を出力する。【選択図】図2
