PROBLEM TO BE SOLVED: To prevent vain operation of an implement connected to a working machine caused by inertia travel motion of the working machine after performing shut-off operation of the power for the travel motion for stopping the working machine.SOLUTION: The structure of a working machine for outputting a pulse signal equipped with a pulse signal output means 22B which outputs information of the working machine by converting the information into the pulse signal to an implement 14 connected to the working machine is provided. The structure for outputting the pulse signal is constructed by installing a calculation means 22A for calculating a travelling velocity based on the output of a rotary sensor 23 for detecting number of rotation of a travelling power, a proceeding direction-output means A for outputting the proceeding direction of the working machine and an intermittent traveling information-output means B for outputting the intermittent information of the travelling power, and the pulse signal output means 22B changes frequency of the pulse signal based on the output of the calculation means 22A and, in addition, changes a duty ratio so that a travelling state of the working machine can be discriminated by the pulse signal based on the output of the proceeding direction-output mens A and the output of the intermittent traveling information-output means B.COPYRIGHT: (C)2010,JPO&INPIT【課題】作業機を走行停止させるための走行用動力の遮断操作を行なった後の作業機の慣性走行によって、作業機に連結した作業装置が無駄に作動することを防止する。【解決手段】作業機に連結した作業装置14に作業機の情報をパルス信号に変換して出力するパルス信号出力手段22Bを備えた作業機のパルス信号出力構造において、走行用動力の回転数を検出する回転センサ23の出力に基づいて走行速度を演算する演算手段22Aと、作業機の進行方向を出力する進行方向出力手段Aと、走行用動力の断続情報を出力する走行用断続情報出力手段Bを備え、パルス信号出力手段22Bが、演算手段22Aの出力に基づいてパルス信号の周波数を変更し、かつ、進行方向出力手段Aの出力と走行用断続情報出力手段Bの出力に基づいて、パルス信号による作業機の走行状態の判別が可能となるようにパルス信号のデューティ比を変更するように構成してある。【選択図】図2
