To achieve proper feed control by obtaining accurate rotation information by a rotary encoder without a risk of disconnection at a low cost.SOLUTION: An automatic feeder 1 includes: a coupling member 8 which couples a member 6c on an output side of an electromagnetic clutch 6 with an output reduction gear 7; a rotary encoder 20 which acquires rotation information on the coupling member 8; and a control section which calculates feed amount of a drilling working machine on the basis of an output signal of the rotary encoder 20 and controls a motor 2 for feed so as to have preset feed amount. The rotary encoder 20 has a section to be detected which is provided in the coupling member 8 and a sensor 20b which is disposed in a casing 9 and detects the section to be detected.SELECTED DRAWING: Figure 2 【課題】低コストでかつ断線のおそれなく、ロータリエンコーダで正確な回転情報が得られるようにし、適切な送り制御を実現する。【解決手段】自動送り装置１は、電磁クラッチ６の出力側の部材６ｃを出力減速機７に結合する結合部材８と、結合部材８の回転情報を取得するロータリロータリエンコーダ２０と、ロータリエンコーダ２０の出力信号に基づいて穿孔作業機の送り量を算出し、予め設定された送り量となるように送り用モータ２を制御する制御部を備えている。ロータリエンコーダ２０は、結合部材８に設けられた被検出部と、ケーシング９の内部に配設され、被検出部を検出するセンサ２０ｂとを有している。【選択図】図２
